Abstract BACKGROUND: Thermal stability signatures of complex molecular interactions in biological fluids can be measured using differential scanning calorimetry (DSC). Evaluating the thermal stability of plasma proteomes offers a method of producing a disease-specific “signature” (thermogram) in neoplastic and autoimmune diseases. OBJECTIVE: The authors describe the use of DSC with human brain tumor tissue to create unique thermograms for correlation with histological tumor classification. METHODS: Primary brain tumors were classified according to the World Health Organization classification. Tumor samples were digested and assayed by a DSC calorimeter. Experimental thermograms were background subtracted and normalized to the total area of transitions to exclude concentration effects. The resulting thermograms were analyzed by applying 2-state, scaled, Gaussian distributions. RESULTS: Differences in glioma-specific signatures are described by using calculated parameters at transitions that are characterized, in the equilibrium approximation, by a melting temperature (Tm), an apparent enthalpy change (ΔH), and a scaling factor related to the relative abundance of the materials denatured in the transition (Aw). Thermogram signatures of glioblastoma multiforme and low-grade astrocytomas were differentiated by calculated values of Aw3 and Tm4, those of glioblastoma multiforme and oligodendrogliomas were differentiated by Aw2, ΔH2, ΔH4, and Tm4, and those of low-grade astrocytomas and oligodendroglioma were differentiated by Aw4. CONCLUSION: Our preliminary results suggest that solid brain tumors exhibit specific thermogram profiles that are distinguishable among glioma grades. We anticipate that our results will form the conceptual base of a novel diagnostic assay based on tissue thermograms as a complement to currently used histological analysis.

Abstract:
The thermophysical properties of vegetable oils were studied by differential scanning calorimetry method was used to study the fatty acid composition of vegetable oils liquid at room temperature, such as amaranth (Amaránthus), corn (Zea mays), flax (Línum usitatíssimum), sunflower (Helianthus), rape (Brusss napor), milk thistle (Sílybum mariánum), saffron milk cap (Camelina sativa) and pumpkin (Cucurbita pepo). The temperatures of the endothermic peak maxima and their area on the DSC thermograms of these oils were established as characteristic thermal effects. The interconnection between thermal effects and fatty acid composition are revealed. On the melting curves of liquid vegetable oils, up to 5 endothermic peaks of different intensities were selected in the ranges -80÷-55 °C, -40÷-15 °C, -25÷-8 °C, -19÷+6 °C and -10÷+4 °C. The coordinates of the maxima of these peaks (Ti) and their area (Si) significantly correlate with the content (Wi,%) in the oils, primarily oleic, linoleic and linolenic acids, the total proportion of which in oils is from 75 to 92%. Using the DSC thermograms of rapeseed oil as an example, it is shown that the program separation of DSC peaks allows a multiple increase in the number of analytical signals, an increase in the reliability of identification of the fat phase, and identification of the main fractions of triglycerides. DSC as a method for identifying vegetable oils using modern thermal analysis instruments is simple to sample, has good reproducibility and can be an independent method for identifying and controlling the quality of vegetable oils.

Abstract:
In order to eliminate the temperature lag effect and obtain the accurate temperature results from hyper differential scanning calorimetry (Hyper-DSC) operated at high heating rate, an adjustable method, namely “Extrapolation Method”, had been introduced by us in former papers. And in this paper, we wanted to support the accuracy of this method by other instruments. Specifically, the extrapolated glass transition temperatures (Tg, 61.5 °C) of PLA film, which was obtained by Hyper-DSC, was close to the value detected directly by normal DSC (62.0 °C). And the extrapolated Tg of waxy starch film (59.7 °C for 8.7% moisture content, and 57.2 °C for 11.2% moisture content) was close to the values detected by modulated temperature DSC (MT-DSC) (63.6 °C and 56.8 °C correspondingly). Consequently, these experimental results support that the “Extrapolation Method” is a feasible way to eliminate temperature lag effect for Hyper-DSC.

Abstract:
Phase transition issues in the field of foods and drugs have significantly influenced these industries and consequently attracted the attention of scientists and engineers. The study of thermodynamic parameters such as the glass transition temperature (Tg), melting temperature (Tm), crystallization temperature (Tc), enthalpy (H), and heat capacity (Cp) may provide important information that can be used in the development of new products and improvement of those already in the market. The techniques most commonly employed for characterizing phase transitions are thermogravimetric analysis (TGA), dynamic mechanical analysis (DMA), thermomechanical analysis (TMA), and differential scanning calorimetry (DSC). Among these techniques, DSC is preferred because it allows the detection of transitions in a wide range of temperatures (−90 to 550 °C) and ease in the quantitative and qualitative analysis of the transitions. However, the standard DSC still presents some limitations that may reduce the accuracy and precision of measurements. The modulated differential scanning calorimetry (MDSC) has overcome some of these issues by employing sinusoidally modulated heating rates, which are used to determine the heat capacity. Another variant of the MDSC is the supercooling MDSC (SMDSC). SMDSC allows the detection of more complex thermal events such as solid–solid (Ts-s) transitions, liquid–liquid (Tl-l) transitions, and vitrification and devitrification temperatures (Tv and Tdv, respectively), which are typically found at the supercooling temperatures (Tco). The main advantage of MDSC relies on the accurate detection of complex transitions and the possibility of distinguishing reversible events (dependent on the heat capacity) from non-reversible events (dependent on kinetics).

Abstract:
Nowadays there is a wide market for cocoa butter equivalents, substitutes and improvers for the confectionery and dairy industries. An urgent task is the development of operational instrumental methods for cocoa butter and its substitutes quality control. Thermophysical parameters are among the most important characteristics of the fat phase for the food technology. Differential scanning calorimetry (DSC) is becoming one of the most promising methods for analytical control of fat and oil products. Thermophysical data (temperatures of the maximums of endothermic peaks and their areas) for cocoa butter and chocolate glaze typical samples applied at dairy processing enterprises of the Central black soil region for the production of chocolate glazed curd bars were obtained in the work performed with its help. DSC data were compared with chromatographic data on triglyceride composition of the fat phase of cocoa butter, cocoa butter equivalents, lauric and non-lauric substitutes, and POP and SOS cocoa butter improvers. It was shown that the DSC method can control the quality of cocoa butter and chocolate glaze, identify chocolate products of different origin and triglyceride composition. Melting thermograms obtained by DSC are highly sensitive to the fat phase triglyceride composition. DSC allows reliable identification of samples of cocoa butter and glaze by melting curves in the temperature range from -100 to +50 ° C. It was found that the main melting peak of cocoa butter and its substitutes, due to the presence of a certain set of triglycerides, is observed in the temperature range from -5 to +30 °C. When examining glazes, the melting peak changes: it bifurcates, expands or narrows. Additional application of computer separation of the unseparated peaks superposition on the DSC melting curves increases the information content of the method and improves the reliability of the fat phase identification. The DSC method is characterized by sample preparation simplicity, has good reproducibility and other metrological characteristics and can be an independent method for fat and oil products identifying and quality control..

Abstract:
A modified method of interpreting a heat flux differential scanning calorimetry records in pore structure determination is presented. The method consists of determining the true phase transition energy distribution due to the melting of water during a differential scanning calorimetry (DSC) heating run. A set of original apparatus functions was developed to approximate the recorded calorimetric signals to the actual processes of the water phase transition at a given temperature. The validity of the proposed calorimetric curves-based algorithm was demonstrated through tests on a cement mortar sample. The correct analysis required taking into account both the thermal inertia of the calorimeter and the thermal effects that are associated with water transitions over the fairly narrow temperature ranges close to 0 °C. When evaluating energy distribution without taking the shifts of the proposed modified algorithm into account, the volume of the pores with radii bigger than 20 nm was greatly overestimated, while that of the smaller pores (rp < 20 nm) was underestimated, in some cases by approximately 70%.

Abstract:
The problem of inaccurate measurement techniques for quantifying isothermal solidification kinetics during transient liquid phase (TLP) bonding in binary and ternary systems; and resulting uncertainty in the accuracy of analytical and numerical models has been addressed by the development of a new technique using differential scanning calorimetry (DSC). This has enabled characterization of the process kinetics in binary and ternary solid/liquid diffusion couples resulting in advancement of the fundamental theoretical understanding of the mechanics of isothermal solidification. The progress of isothermal solidification was determined by measuring the fraction of liquid remaining after an isothermal hold period of varying length. A 'TLP half sample', or a solid/liquid diffusion couple was setup in the sample crucible of a DSC enabling measurement of the heat flow relative to a reference crucible containing a mass of base metal. A comparison of the endotherm from melting of an interlayer with the exotherm from solidification of the residual liquid gives the fraction of liquid remaining. The Ag-Cu and Ag-Au-Cu systems were employed in this study. Metallurgical techniques were used to compliment the DSC results. The effects of sample geometry on the DSC trace have been characterized. The initial interlayer composition, the heating rate, the reference crucible contents, and the base metal coating must be considered in development of the experimental parameters. Furthermore, the effects of heat conduction into the base metal, baseline shift across the initial melting endotherm, and the exclusion of primary solidification upon cooling combine to systematically reduce the measured fraction of liquid remaining. These effects have been quantified using a modified temperature program, and corrected using a universal factor. A comparison of the experimental results with the predictions of various analytical solutions for isothermal solidification reveals that the moving interface solution can accurately predict the interface kinetics given accurate diffusion data. The DSC method has been used to quantify the process kinetics of isothermal solidification in a ternary alloy system, with results compared to a finite difference model for interface motion. The DSC results show a linear relationship between the interface position and the square root of the isothermal hold time. While the numerical simulations do not agree well with the experimental interface kinetics due to a lack of accurate thermodynamic data, the model does help develop an understanding of the isothermal solidification mechanics. Compositional shift at the solid/liquid interface has been measured experimentally and compared with predictions. The results show that the direction of tie-line shift can be predicted using numerical techniques. Furthermore, tie-line shift has been observed in the DSC results. This study has shown that DSC is an accurate and valuable tool in the development of parameters for processes employing isothermal solidification, such as TLP bonding.

Abstract:
Cardiac contraction at the level of the sarcomere is regulated by the thin filament (TF) composed of actin, alpha tropomyosin (TPM), and the troponin (Tn) complex (cTnT: cTnC: cTnI). The "gate-keeper" protein, α-TPM, is a highly conserved α-helical, coiled-coil dimer that spans actin and regulates myosin-actin interactions. The N-terminus of one α-TPM dimer inter-digitates with the C-terminus of the adjacent dimer in a head-to-tail fashion forming the flexible and cooperative TPM-overlap that is necessary for myofilament activation. Two dilated cardiomyopathy (DCM) causing mutations in TPM (D84N and D230N) and one hypertrophic cardiomyopathy (HCM) causing mutation (E62Q), all identified in large, unrelated, multigenerational families, were utilized to study how primary alterations in protein structure cause functional deficits. We hypothesize that structural changes from a single point mutation propagate along the -helical coiled-coil of TPM, thus affecting its regulatory function. Structural effects of the mutations studied via differential scanning calorimetry (DSC) on TPM alone revealed significant changes in the thermal unfolding temperatures of both the C- and N-termini for all mutants compared to WT, indicating that mutational effects propagate to both ends of TPM, thus affecting the overlap region. Although, of note, the proximal termini to the mutation has shown more significant structural changes compared to WT. DSC analysis on fully reconstituted TF’s (Tn:TPM:Actin) revealed effects on the TPM-Actin cooperativity of activation, affecting interaction strength (thermal stability), and the rigidity of TPM moving along actin (FWHM). To characterize the resultant functional effect of these discrete changes in thermal stability and TPM rigidity, ATPase assays were used to measure actomyosin activation in the presence and absence of Ca2+. Together, these data will provide a molecular level understanding of the structural and functional deficits caused by these mutations to help elucidate the mechanisms leading to disease.

Abstract:
Bakgrunden till detta examensarbete var att Qumex Materialteknik vid ett flertal tillfällen konstaterat att material av typen SS 0725 har uppvisat bristfälliga härdresultat. Materialet, som är relativt nytt på marknaden, är ett gjutjärn av typen segjärn och utmärker sig gentemot andra segjärn på grund av sitt höga innehåll av kisel. Då segjärn enligt den nu gällande EN-standarden klassificeras efter sina mekaniska egenskaper uppstår ett problem gällande SS 0725. Materialet uppfyller de krav som är ställda för EN-GJS-500-7 och hamnar därmed under samma materialbeteckning som ett segjärn med betydligt lägre kiselhalt. Att två material med olika kemisk sammansättning hamnar under samma beteckning kan innebära problem. Syftet med denna rapport är att fastslå vilken påverkan den höga kiselhalten har på materialet vid värmebehandling av typen släckhärdning med efterföljande anlöpning. I försöken ingick fyra material. Det som skiljde materialen åt var halterna av koppar och kisel. De härdades vid tre olika temperaturer och under tre olika tider för att sedan släckas i olja. Målet med släckhärdningen var att materialen skulle få en helt martensitisk struktur vilket då klassades som ett bra härdresultat. Resultatet utvärderades sedan genom optisk mikroskopi och hårdhetsmätningar. En undersökning av materialens fasomvandlingstemperaturer genomfördes med hjälp av Differential Scanning Calorimetry. Resultatet visar att kiselhalten har stor påverkan på den temperatur som krävs för att erhålla ett bra härdresultat. För material med låg kiselhalt uppnåddes fullständig martensitbildning efter släckhärdning från 840°C. För material med hög kiselhalt uppnåddes liknande strukturella och hårdhetsmässiga resultat först vid en så hög temperatur som 900°C och behandlingstider längre än 1 h. Den relativa skillnad som uppmättes i fasomvandlingstemperatur med hjälp av Differential Scanning Calorimetry mellan högkiselmaterial och lågkiselmaterial var 45°C. Detta resultat kombinerat med analyserna av härdprocesserna visar att det krävs kraftigt ökad temperatur vid värmebehandling av högkiselmaterialet SS 0725.
The background to this thesis was that Qumex Materialteknik at several occasions had received material of type SS 0725 that had shown deficient heat treatment results. The material, which is relatively new, is a cast iron of type ductile iron and differ against other ductile irons because of its high silicon content. According to EN standard ductile irons are classified by their mechanical properties. A problem then occurs with the new material SS 0725 because of this. The material fulfils the requirements for EN-GJS-500-7 and is therefore in the same classification as a ductile iron with much lower silicon content. Two materials having major differences in chemical composition ending up in the same classification can be problematic. The purpose of this report is to determine impact of high silicon content in ductile iron when heat treated and quench hardened. The experiment included four materials, and the major difference between the materials were their content of copper and silicon. The heat treatment process was performed at three different temperatures and three different treatment times. Afterwards the samples were quenched in oil. The ambition of the quench hardening was to obtain a material structure of 100% martensite. By optical microscopy and hardness measurements the results then were evaluated. An investigation of the phase transformation temperature in the materials was made by using Differential Scanning Calorimetry. The results show that the amount of silicon content has great influence on the temperature for receiving good hardening results. To achieve 100% martensite after quench hardening in materials with low silicon content the temperature needs to be over 840°C. For material with high level of silicon content the temperature for achieving 100% martensite needs to be 900°C and the treatment time should be over 1 h. The relative difference in phase transformation temperature was measured using Differential Scanning Calorimetry. The results of the measurements between the materials with high silicon content and materials with low silicon content was 45°C. This result combined with the analysis of the heat treatment process shows that a major increase of the temperature is needed to heat treat SS 0725.

Abstract:
In recent years, the application of thermal analysis to study the combustion and pyrolysis behavior of fossil fuels has gained a wide acceptance because of its significance for industry and economy. In this thesis, the thermal and kinetic analysis of different origin crude oil samples are performed by two well-known thermal analysis techniques: Differential Scanning Calorimetry (DSC) and Thermogravimetry (TG/DTG). The investigation of combustion and pyrolysis behaviors, kinetic analysis of oil samples and the determination of heating rate effect are the main objectives of this study. Six different crude oils from the Southeastern region of Turkey are analyzed throughout the study. All experiments are performed at different heating rates (5, 10 and 15º
C/min) and air is used for combustion and nitrogen for pyrolysis experiments. In combustion experiments, TGA and DSC techniques indicate that the combustion process of crude oils studied is composed of two main reaction regions. These are low-temperature (LTO) and high-temperature oxidation (HTO) regions. In LTO, huge mass loss occurs (from 69 to 87 %) due to high amount of free moisture and volatile hydrocarbons contained in oil samples. Combustion reactions continue up to 900 K. On DSC curves, two exothermic regions of oxidation regimes are detected. Comparing TG/DTG and DSC curves, it can be understood that the mass loss under combustion is accompanied by exothermic peaks because of the oxidative degradation of crude oil components. As in combustion, two distinct reaction regions are revealed under pyrolysis for all samples. The first region indicates distillation and the second one is due to thermal cracking reactions occur at high temperatures and completed up to 840 K. As expected, lighter crude oils have relatively higher amounts of mass loss in distillation region as compared to heavier ones. Besides, residue amount and burn-out temperatures are higher for heavier oils with higher asphaltene content in cracking region. DSC curves for both reactions show endothermic effects. In combustion and pyrolysis experiments, it is noticed that higher heating rates are resulted in higher reaction regions. Distinguishing peaks of samples shift to higher temperatures with an increase in heating rate. Heat of reaction amount under DSC curves is related to asphaltene content and &
#730
API gravity of crude oils. It is deduced that, when &

API gravity of crude oils decreases, the heat value of this reaction increases. The kinetic parameters are evaluated by different kinetic models and mean activation energies (Em) of samples are obtained. At the end, a correlation is established between Em and &

API gravity of oil samples. It is concluded that heavier oils have higher activation energy and Arrhenius constant values for each reaction region. Besides, it is proved that the activation energy is mostly insensitive to the heating rate.

Abstract:
Mit der Entwicklung und Einführung ökologischer Bauweise im Neubau sowie neuen Baustoffsystemen in Sandwichbauweise wird es zunehmend erforderlich, neue effektive Befestigungsvarianten zu entwickeln, die eine dauerhafte Fixierung auch unter sicherheitstechnischen Bestimmungen sowie aus Garantie- bzw. haftungsrechtlichen Gründen ermöglichen. Die aus der Praxis bisher bekannten chemischen Befestigungssysteme (Zweikomponentenverbundmörtel, Verbundankerpatronen) weisen hinsichtlich der Applikation unter bautechnischen Bedingungen noch einige Nachteile auf. Dazu gehören vor allem längere Aushärtungszeiten zur Realisierung der abschließenden Verbundfestigkeit, Inhomogenitäten im Verbund, der Einsatz toxischer Verbindungen und eine Limitierung der Applikationsmöglichkeiten in horizontalen und Überkopf-Einsatzbereichen sowie Hohlkammersystemen. Alle zuvor genannten Punkte haben bis jetzt die Nutzung solcher Verbundwerkstoffe als universale Anwendungsmöglichkeit verhindert. Ein neues chemisches Befestigungssystem, welches aus Novolak gehärteten mit Hexamethylentetramin (Hexa) und anorganischen Füllstoff besteht, wurde für Applikationen in Beton entwickelt. Das Bindemittel härtet bei der Temperaturzuführung aus. Die unkatalysierte Befestigungsmasse zeigt bei einer Temperatur zwischen 150-300 °C eine hohe Reaktivität. Die Vorteile dieses Systems sind die unbegrenzte Lagerfähigkeit der vorgemischten härtbaren Masse sowie die Gewährleistung einer homogenen Netzwerkstruktur im gesamten Verbund und sie ist frei von giftigen und flüchtigen Substanzen. Auf den Einsatz toxischer Substanzen wurde verzichtet. In dieser Arbeit wurde die Gesamtkinetik der Reaktion während des Aushärtungsprozesses dieser Polymerkomposite untersucht. Die DSC- (nicht-isothermen, isothermen) und MDSC-Untersuchungen haben sich als ein sicheres Verfahren zur Qualitätskontrolle des Aushärtezustands der Befestigungssysteme herausgestellt. Parallel zur nicht-isothermischen und isothermischen DSC wurden Leitfähigkeitsmessungen durchgeführt, um den Endpunkt der Aushärtungsreaktion zu bestimmen
The development and introduction of ecological construction methods and the use of sandwich materials make it necessary to develop new fixing systems and technologies. Dealing with the application in concrete and other substrates commercial chemical fixing systems show some disadvantages up to date. Especially the rather long curing time in order to realize the final bond strength, inhomogenities in the composite, the partial use of toxic substances and application limits of such systems in horizontal direction as well as hollow section materials has so far prevented the use of such composites for all-purpose applications. A new chemical fixing system, which consists of hexamethylene tetramine (hexa) cured novolac and inorganic filler, was developed for application in concrete. It is applied by a thermo-curing procedure. The uncatalyzed curable mixture has a high reactivity at temperature between 150-300 °C. Compared with commercial chemical fixing systems, the premixed curable mass has many benefits. First it has a unique storage stability and second, it is free of toxic and volatile substances. Another important aspect is, it is self-foaming. In this study was investigated the overall kinetics of the reaction during the curing process of these polymer composites. An appropriate method for this experiment proved to be the DSC in isothermal and non-isothermal mode and MDSC. This turned out to be a safe quality control technique for these systems. Parallel to the non-isothermal and isothermal DSC conductivity measurements have been performed to determine the end point of the curing reaction

Abstract:
In this thesis, four different crude oil samples and their saturate, aromatic and resin fractions were analyzed by two different thermoanalytical methods, thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC). The experiments were performed at three different heating rates (5, 10 and 15 °
C/min) under air atmosphere. Same gas flow rate and same pressure were applied to all samples. The aim is to determine the kinetic analysis and combustion behavior of crude oils and their fractions and also determining the effect of heating rate on all samples. For all samples two main reaction regions were observed in thermogravimetry (TG), differential thermogravimetry (DTG) and DSC curves due to the oxidative degradation of crude oil components. It was deduced that the free moisture, volatile hydrocarbons were evaporated from the crude oils, light hydrocarbons were burned and fuel was formed in the first reaction region. The second reaction region was the main combustion region where the fuel was burned. From the TGA curves, it was detected that the heavier fraction, resins, lost considerable amounts of their initial mass, approximately 35%, while saturates lost only approximately 3% of their initial mass in the second reaction region. DSC curves of the samples were also examined and observed that as the sample got heavier, the heat of the reaction increased. Saturates, lightest part of the crude oil fractions, gave minimum heat of reaction. As the heating rate increased, shift of peak temperatures to high values and higher reaction regions were observed. The kinetic analysis of crude oils and their fractions were also performed using different kinetic methods. Activation energies (E), mean activation energies (Emean) and Arrhenius constants were found for crude oils and fractions. It was deduced that the resins gave the highest activation energy and Arrhenius constant for both reaction regions. Moreover, it was encountered that heating rate has no effect on activation energies.

Dissertação para obtenção do Grau de Mestre em Engenharia Química e Bioquímica
In the present work a stochastic model to be used for analyzing and predicting experimental data from simultaneous thermogravimetric (TG) and differential scanning calorimetry (DSC) experiments on the thermal and catalytic degradation of high-density polyethylene (HDPE) was developed. Unlike the deterministic models, already developed, with this one it’s possible to compute the mass and energy curves measured by simultaneous TG/DSC assays, as well as to predict the product distribution resulting from primary cracking of the polymer, without using any experimental information. For the stochastic model to predict the mass change as well as the energy involved in the whole process of HDPE pyrolysis, a reliable model for the cracking reaction and a set of vaporization laws suitable to compute the vaporization rates are needed. In order to understand the vaporization process, this was investigated separately from cracking. For that, a set of results from TG/DSC experiments using species that vaporize well before they crack was used to obtain a global correlation between the kinetic parameters for vaporization and the number of C-C bonds in the hydrocarbon chain. The best fitting curves were chosen based on the model ability to superimpose the experimental rates and produce consistent results for heavier hydrocarbons. The model correlations were implemented in the program’s code and allowed the prediction of the vaporization rates. For the determination of the global kinetic parameters of the degradation reaction to use in the stochastic model, a study on how these parameters influence the TG/DSC curves progress was performed varying those parameters in several simulations, comparing them with experimental data from thermal and catalytic (ZSM-5 zeolite) degradation of HDPE and choosing the best fitting. For additional improvements in the DSC stochastic model simulated curves, the thermodynamic parameters were also fitted. Additional molecular simulation studies based on quantum models were performed for a deeper understanding on the reaction mechanism and progress. The prediction of the products distribution was not the main object of the investigation in this work although preliminary results have been obtained which reveal some discrepancies in relation to the experimental data. Therefore, in future investigations, an improvement of this aspect is necessary to have a stochastic model which predicts the whole information needed to characterize HDPE degradation reaction.

Abstract:
Glasses of the systems Ge-Se-X (X = Ga, Sn, Bi, Sb), Ge-S-Y (Y = Ag, Ga, Sn, Bi) and Se-S have been examined using X-ray photoelectron spectroscopy (XPS), X-ray diffraction (XRD), density and differential scanning calorimetry (DSC). Two of the compositions, GeSe2 and (GeSe2)92Ga8, have also been examined by extended X-ray absorption fine structure (EXAFS) and X-ray absorption near edge structure (XANES). The emphasis of the XPS measurements was on the changes in the binding energies with composition of the core peaks of the glasses, and on the plasmon energy losses from the L3M4,5M4,5 Auger lines of Se and Ge. It was found that there were small shifts in the binding energies of the core peaks on substitution but the plasmon energy changed markedly with composition. For the XRD measurements, the focus was on two features : (a) to ensure that the samples prepared were truely amorphous and (b) to confirm the presence of the first sharp diffraction peak (FSDP) on the interference functions. The density measurements showed that the addition of the third element (X or Y) to the binary resulted in an increase in the relative density except for one system, Ge-Se-Sn, which showed the opposite behaviour. The DSC measurements showed that the addition of the third element to the binary resulted in a decrease in the glass transition temperatures. The EXAFS and XANES measurements of GeSe2 and (GeSe2)92Ga8 glasses showed that there was very little change in the local order around the Ge atom in GeSe2 glass with increase in temperature and that the local order around the Ge atom changes on alloying GeSe2 with Ga. Correlations between parameters and measured properties of the ternary alloys have been investigated. It has been found that the parameter , the average coordination number, correlates well with certain structural properties but badly with others. Suggestions are made for an alternative to .

Abstract:
Calorimeters are critical tools for structural based drug design and drug stability assessment. Current pharmaceutical industry is seeking for high throughput calorimeters to reduce the research time and expenditure. MEMS-based calorimeter is a potential solution for it, since they are miniaturized to detect the enthalpy change during macro molecular interaction with smaller amount of samples, shorter time and could easily enable parallel measurement. Consequently, we present a Differential Scanning Calorimeter (DSC) that requires 2μL sample volume. It has high thermal insulation (1210μW/K), small time constant (6.95s) and high sensitivity (7.5V/W). The low noise equivalent temperature difference (NETD) could lead to 130nW of power resolution. These characterization results indicate the device could be potentially applied for macromolecular interaction application and increase the throughput with high performance.

Abstract:
Differential Scanning Calorimetry (DSC) measurements are routinely used to determine enthalpies of phase change, phase transition temperatures, glass transition temperatures, and heat capacities. In order to obtain data on the amount of phases during phase change, time-temperature lags, which are inherent to the measurement process, must be estimated through a computational analysis. An analytical model is proposed for the systematic error of the instrument. Numerical simulation results are compared against experimental data obtained at different heating and cooling rates.

Abstract:
Radiation damage in structural materials for nuclear applications is not well-understood, especially when linking the atomic scale damage mechanisms to the macroscopic effects. On a microscopic level, particle radiation creates defects that can accumulate in the material. Defects can also interact with existing features in the material. Since both defects and features have different energies associated with them, investigation of the resulting energy spectrum in a macroscopic sample may offer insight into the connection between microscopic damage and macroscopic properties. In alloys, changes in the size and number of precipitates will be reflected in the amount of energy required to dissolve the precipitates during thermal analysis. This can then be studied using differential scanning calorimetry (DSC). This work explores the sensitivity of the DSC measurement to detect irradiation-induced instability in metastable and secondary phase precipitates in the high-strength aluminum alloy 7075-T6 for extremely low doses of helium-ion and neutron irradiation. The precipitates in aluminum 7075-T6 are expected to grow or shrink, changing the energy spectrum measured by DSC. The magnitude of the change can then be compared to a model of irradiation-induced phase instability. This will demonstrate the ability of this thermal analysis technique to help bridge the gap between microscopic radiation effects and macroscopic properties.

The implementation of the Generation IV nuclear reactors and a spallation target of the accelerated driven system (ADS) concerning to the use of liquid lead-bismuth eutectic (LBE) alloy. The liquid LBE alloy should be fully characterized and especially its physical properties should be completely known to make sure the nuclear safety. Differential scanning calorimetry (DSC) experiments were employed on LBE alloy at a temperature range of room temperature (RT) to 500°C to detect the structure phase transition and obtain the thermal effect of LBE alloy. The results of DSC curves showed that there existed two remarkable thermal signal events at the melting points zones of Pb and Bi during the melting process tested with a scan rate of 2°C/min. Even though the scan rate was increased to 5°C/min, the DSC signal still exhibited the changes of curve slop at the element melting point zone. Just this interesting DSC thermal signal change phenomenon around 300°C contributed to the relationship with the explanation on the severe embrittlement of T91 steel induced by liquid LBE alloy. The results suggest that there existed effective critical size and form of chemical clusters in liquid LBE alloy worked actively on the embrittlement of T91 Steel.

This paper presented a MEMS based differential scanning calorimeter (DSC) for biomolecular characterization. In this MEMS based DSC, PDMS (Polydimethylsiloxane) and Flexdyne thin film were used to construct the microfluidic chamber. Polyimide were used to fabricate the flexible substrate and temperature sensitive vanadium oxide was used as the thermistor material. A heating stage was used to heat the sample and reference up at a certain rate. The resolution study and step response characterization indicated the high sensitivity (6.1V/W) of the device. The test with Bovine Serum Albumin (BSA) samples showed clear phase transitions and the data was confirmed to be reasonable by comparing it with the results of commercial DSC’s test. This device used 0.63uL sample amount and could complete the scanning process in 3 minutes, significantly increasing the throughput of the biomolecular thermodynamics study like protein denaturation process compared to the traditional DSC (1 to 2 hours).

Full text
Abstract:
In cryopreservation protocols maximum survivability is achieved when cooling occurs slowly enough to avoid Intracellular ice formation (IIF) yet fast enough to avoid solute effects injury (1). IIF plays a significant role in cell damage during cryopreservation. IIF has been extensively studied using cryomicroscopy. This technique is a useful tool to understand the dynamic processes during cooling, i.e. volume change of cells and IIF occurrence associated with temperature. However it has some limitations in being applied to biological systems. The central assumption in cryomicroscopy is that the projected two-dimensional area of the cell can be extrapolated to a spherical three-dimensional volume. While reasonable for spherical cell systems, this assumption is inappropriate for obtaining quantitative volumetric information in nonspherical cell systems. Differential scanning calorimetry (DSC), however, can be applied to nonspherical cell systems. Thus, DSC exotherms during freezing needed to be compared with cryomicroscopy observations in simple spherical cell systems. Several studies related to IIF using DSC havebeen reported (2)–(5). Most of them, however, discussed only IIF peaks and/or Extracellular ice formation (EIF). In order to predict the optimum cooling rate from DSC results, it is important to quantify not only IIF and EIF but also water transport (WT) during cooling at various cooling rates.

Abstract:
By definition, a differential scanning calorimetry (DSC) requires a sample structure and a refrence structure to obtain the latent heat of a speicman. We propose a novel approach, named Phase Transition Calorimetry (PTC), to obtain the specimen’s latent heat by using only the signal from the sample bridge. The new setup and procedure are primarily based on electrical resistance heating and thermometry and the parametric estimation method by solving the heat conduction equation with and without the phase transformation. The new setup has two major advantages over widely used DSC setups: there are no errors associated with heat loss to the surroundings, and the uncertainty resulting from the difference between the sample and the reference is eliminated by removing the reference structure. Experimental validation of the new setup and procedure is demonstrated by measuring the latent heat of thin layers of tin. This was found to be 4.1×108 Jm−3, which is different within 5% from the literature values of bulk specimens.
