Résumé :

This paper explores the development laws of the fluidity, compressive strength, and autogenous shrinkage of ultrahigh performance cement (UHPC) mixed with limestone powder (LP) and highly active ground slag powder (SP). A microscopic analysis was conducted on the hydration products and pore structures. Through quantitative research on the packing density and fractal dimension of particles in different systems, the relationship between particle characteristics and UHPC properties was established. As a result, the packing densities of the UHPC mixed solely with LP (binary system) and UHPC mixed with LP and silica fume (ternary system) are higher than those of UHPC mixed with the same amount of SP and the benchmark UHPC system; fractal dimension of particle size distribution is closely related to packing density. The LP-cement-silica fume ternary system was lowly hydrated, but it has a good grain composition and high density of slurry, which improved the compressive strength of UHPC. The compressive strength of UHPC mixed with 50% LP witnessed a more obvious decline than that of the ternary system and the one with the same amount of SP. The reason lies in the decrease in slurry due to a lack of sufficient active constituents, and the hydration products were far from enough to fill the pores in the system. LP can also inhibit autogenous shrinkage to the greatest degree for the LP-mixed binary system performed best in such inhibition.

Résumé :

Powder packing in metal powders is an important aspect of additive manufacturing (otherwise known as 3-D printing), as it directly impacts the physical and mechanical properties of materials. Improving the packing density of powder directly impacts the microstructure of the finished 3D-printed part and ultimately enhances the surface finish. To obtain the most efficient packing of a given powder, different powder blends of that material must be mixed to minimize the number of voids, irrespective of the irregularities in the particle morphology and flowability, thereby increasing the density of the powder. To achieve this, a methodology for mixing powder must be developed, for each powder type, to obtain the maximum packing density. This paper presents a model that adequately predicts the volumetric fraction of the powder grades necessary for obtaining the maximum packing density for a given powder sample. The model factors in the disparity between theoretical assumptions and the experimental outcome by introducing a volume reduction factor. We outline the model development steps in this paper, testing it with a real-world powder system.

Résumé :

The phase equilibria in the ternary systems {Ce, Gd}–{Ti, Zr}–Sb were investigated by means of X-ray powder diffraction and energy-dispersive X-ray spectroscopy. The isothermal sections of the phase diagrams at 600°C were constructed. The formation of three ternary compounds (Ce2Ti7Sb12, Ce3TiSb5, and Gd2Ti11Sb14) was confirmed in the {Ce, Gd}–Ti–Sb systems and no more ternaries were found. The investigation of the {Ce, Gd}–Zr–Sb systems revealed several new ternary compounds and confirmed the known ones. The crystal structure of the new compound Ce0.08(3)Zr1.92(3)Sb was determined from X-ray powder diffraction data. The other new compounds in the Ce–Zr–Sb system were found to have compositions close to ~CeZrSb4and ~Ce2Zr3Sb5. In the Gd–Zr–Sb system the existence of a large homogeneity range was established for the GdZrSb compound along the isoconcentrate 33.3 at.% Sb: Gd1-xZr1+xSb (x= 00.905(18) at 600°C), and a new compound, ~Gd3Zr3Sb14, was discovered. The crystal structures at the boundary compositions of the Gd1-xZr1+xSb phase were refined from X-ray powder diffraction data.

Résumé :

Curcumin is the major phenolic diarylheptane derivative in Curcuma longa and has been reported to possess pharmacological activities. Unfortunately this compound suffers from poor bioavailability and rapid neutral-alkaline degradation. Co-crystal of curcumin is one option under exploration, motivated by the fact that a number of active pharmaceutical ingredient (API) co-crystals with improved dissolution have recently been synthesized. Hence, co-crystallization technique highlights an alternative means to improve the performance of curcumin. Within our work evidences for a co-crystal was ascertained from DSC, Kofler hot stage screening and PXRD, and all confirmed a new crystal phase could have been formed between curcumin and a co-crystallizing agent, nicotinamide. We report that re-crystallization step essentially aids the purification of commercial curcumin, a herbal based actives. Otherwise the prevalence of a new crystal phase in solvent-mediated co-crystallization will be significantly reduced. Besides, phase diagram is an effective tool for the study of solubility behaviours in co-crystal system. In order to acquire related techniques, fenbufen, a poorly water soluble drug, was selected. The result showed the huge difference in solubility between fenbufen and nicotinamide lead to difficulty in the construction of phase diagram.

Résumé :

The production of stable solid crystalline material is an important issue in the pharmaceutical industry and the challenge to control the desired active pharmaceutical ingredient (API) with the specific chemical and physical properties has led to more development in the drug industry. Increasing the solubility and the dissolution of the drug will increase its bioavailability; therefore the solubility can be improved with the change in the preparation method. The formation of co-crystals has emerged as a new alternate to the salts, hydrates and solvate methods since the molecules that cannot be formed by the usual methods might crystallise in the form of co-crystals. Co-crystals are multicomponent crystals which can be known as supramolecules and are constructed by the non covalent bonds between the desired former and co-former. Therefore the synthon approach was utilised to design co-crystals with the specific properties, this involves the understanding of the intermolecular interactions between these synthons. These interaction forces can be directed to control the crystal packing in the design of the new crystalline solid with the desired chemical and physical properties. The most familiar synthon was the amide group with its complementary carboxylic group, in this work isonicotinamide and benzoic acid were chosen to design co-crystal and much literature exist that introduce the determination of co-crystal growth from these two compounds. The growth of co-crystals was carried out in water, ethanol and ethanol / water mixed solvent (30 - 90 % ethanol) by utilising the Cryo-Compact circulator. Co-crystals (1:1) and (2:1) were grown in ethanol and water respectively and a mixture of both phases were grown in the mixed solvent. All the phases were examined by powder X-ray diffraction (PXRD), Raman, Infrared and 1H-NMR spectroscopy. The solubility of isonicotinamide, benzoic acid, co-crystals (1:1) and (2:1) in water, ethanol and ethanol/water mixed solvent (30 - 90 % ethanol) were determined at 25 °C, 35 °C and 40 °C by utilising the React-Array Microvate. It was important to understand some of the thermodynamic factors which control the formation of these polymorphs such as the change in the enthalpy and the change in the entropy. Also it was important to study the pH behaviour during dissolution of the former, co-former and co-crystals in water, ethanol and ethanol/water mixed solvent (30 - 90 % ethanol) in-order to examine the affect of the solvent composition on the solubility and to identify if some ions were formed during the dissociation and how this could affects the formation of co-crystals. A discussion has been introduced in this research of how similar solubility of the compounds maps the formation of the typical ternary phase diagram of the mixture of 1:1 while compounds with different solubility maps the formation of skewed phase diagram as shown in section 1.6.2.3. In this project an isotherm ternary phase diagram at 20 °C and 40 °C was constructed to map the behaviour of benzoic acid and isonicotinamide and to show all possible phases formed and the regions where all phases are represented in the ternary phase diagram were determined by the slurry method. The ternary phase diagram was used to design a drawn out and cooling crystallisation at 100 cm3 solution of 50 % ethanol / water mixed solvent and a study of the impact of seeds of co-crystals 1:1 on the cooling crystallisation method.

Résumé :

La construction en terre est considérée comme une construction verte en utilisant des matériaux disponibles localement avec un faible impact environnemental et une performance thermique supérieure. Malgré les avantages de ce matériau de construction, le processus de coulage est très consommateur de temps et d'énergie à cause de l’application de la compaction dynamique. Cette étude a pour but d'évaluer la faisabilité de formuler un béton de terre autoplaçant (BTAP) tout en étudiant ses performances rhéo-thermomécaniques et en identifiant les différents défis. Le premier défi est la présence de particules fines dans la terre, en particulier les particules argileuses, qui peuvent entraver la fluidité du BTAP. L’augmentation du temps de prise est le deuxième défi en raison de la faible teneur en ciment. Le dernier défi vient de la diversité des terres avec des comportements différents, ce qui rend difficile la proposition d'une ligne directrice complète pour la conception des BTAP.Des solutions potentielles ont été introduites pour réaliser le BTAP afin de remédier à l'inefficacité des matériaux en terre. Il s’agit essentiellement de comprendre l'efficacité de différents adjuvants chimiques en présence des systèmes de poudre ternaire (c'est-à-dire l'argile, le limon et le ciment). Une nouvelle approche de mortier du béton équivalent (MBE) a été introduite à la Phase 3. En conséquence, le MBE et les formulations de béton ont été étudiés pour vérifier la faisabilité du BTAP. Les caractéristiques hygrothermiques et microstructurales des BTAP optimisés ont été étudiées. Ce nouveau matériau offre une microstructure conduisant à une performance hygrothermique différente de celle des matériaux en terre conventionnels
The earth construction is identified as a green construction by using locally available materials with low environmental impacts and superior thermal performance. Besides all the advantages of this construction material, the casting process can be very time and energy consuming due to the nature of dynamic compaction. This study aimed to evaluate the feasibility of achieving self-consolidating earth concrete (SCEC) with introduction of its potential challenges and investigating its rheo-thermomechanical performance. As the first challenge, the presence of fine particles in earth, especially clay, can hinder the flowability of SCEC. Promoting the setting time is the second challenge due to the low cement content. The last challenge comes from the diversity of earth with different behaviors which makes it difficult to propose a comprehensive guideline to design SCEC.Potential solutions were introduced to achieve SCEC and address the inefficiency of earth materials. The main objective was to understand the efficiency of different chemical admixtures in presence of various ternary powder systems (i.e., clay, silt, and cement). A new concrete-equivalent mortar (CEM) approach was introduced in the Phase 3. Accordingly, the CEM and concrete mixtures were investigated to verify the feasibility of SCEC. The hygrothermal and microstructural characteristics of the selected SCEC mixtures were investigated. This novel material offers a new microstructural system, hence leading to a different hygrothermal performance compared to conventional earthen materials

Résumé :

Research on salts species formed by evaporation of aqueous solution of Na2 in the early 1930s. The thermodynamic, crystallographic and many other physical and chemical properties of most of the species formed from this solution has been known for decades. However, there was no complete information or reliable data to confirm the existence of a unique double salt that is rich in sodium carbonate, up until five years ago when a research identified the double salt (~2Na ₂ CO ₃ • Na ₂ SO ₄) from the ternary system Na₂CO ₃Na₂SO ₄ H₂O. Crystallization of this double salt so called sodium sulfate dicarbonate (~2Na ₂ CO ₃ • Na ₂ SO ₄) is known to be a primary contributor to fouling heat transfer equipment in spent-liquor concentrators used in the pulp and paper industry. Therefore, understanding the conditions leading to formation of this double salt is crucial to the elimination or reduction of an industrial scaling problem. In this work, double salts were generated in a batch crystallizer at close to industrial process conditions. X-ray diffraction, calorimetry, and microscopic observation were used to investigate the stability of the salts to in-process aging, isolation and storage, and exposure to high temperature. The results show that care must be taken during sampling on evaporative crystallization. Two apparent crystal habits were detected in the formation of sodium sulfate dicarbonate; the favored habit may be determined by calcium ion impurities in the system. The results also verify that sodium sulfate dicarbonate exists as a unique phase in this system and that remains stable at process conditions of 115-200℃

Résumé :

7YSZ (yttria stabilized zirconia) was co-doped with metal oxides of different valence, ionic radius and mass in order to investigate microstructural and property changes as a result of co-doping. Mechanical alloying process was used to produce the powder blends which were subsequently sintered at 1500°C for 120 hours. The results from SEM, XRD and DSC showed that the microstructures of the co-doped ternary oxides were affected by the amount of oxygen vacancies in the system, the co-dopant cation radius and mass. Increasing the number of oxygen vacancies by the addition of trivalent co-dopant (Yb2O3 and Sc2O3) as well as the use of larger cations promoted the stabilization of cubic phase. The tetravalent co-dopant (CeO2), on the other hand, had the effect of stabilizing tetragonal phase which may transform into monoclinic phase during cooling, depending on the concentration of tetravalent co-dopant and the mass. Smaller cation mass had the effect of reducing the transformation temperature from tetragonal to monoclinic phase. Pentavalent co-dopants (Nb2O5 and Ta2O5) were found to stabilize the tetragonal phase at high temperature; however, the stability of the tetragonal phase upon cooling was determined by the mass and ionic radius of the co-dopants. Cation clustering was observed during cooling in trivalent oxide co-doped 7YSZ while clustering of trivalent and pentavalent cations in pentavalent co-doped 7YSZ was not detected. Additionally, from the thermal conductivity measurement results, it was found that trivalent oxides exhibited the most significant effect on reducing the thermal conductivity of ternary oxides; this trend was followed by pentavalent co-doping oxides whereas the tetravalent CeO2 co-doped 7YSZ showed marginal effect. A semi-empirical thermal conductivity model was established based on defect cluster model and the predicted room temperature thermal conductivity values were found to be consistent with that measured experimentally. Furthermore, the incorporation of co-dopant oxide in 7YSZ was observed to substantially modify the elastic modulus of the ternary oxides. More specifically, the addition of co-dopant with larger cation radius was found to reduce the elastic modulus of 7YSZ due to the increase in lattice parameter(s).

Résumé :

The heat flux on the receiver tube is non-uniform because of uneven solar flux and receiver structure, which causes overheating and thermal stress failure of receiver and affected safe operations of the Concentrated Solar Power (CSP) system. In order to reduce the temperature difference in receiver tube wall and improve the efficiency of CSP system, the ternary eutectic salt LiF-NaF-KF (46.5-11.5-42 wt.%, hereafter FLiNaK), which has a better high thermal stability than that of nitrate salts at operating temperature of 900 °C, is selected as HTF, and heat transfer performance of FLiNaK in a corrugated receive tube with non-uniform heat flux is simulated by CFD software in the present work. The numerical results reveal that the non-uniform heat flux has a great influence on the temperature distributions of the receive tube and FLiNaK salt. Compared with the result of bare tube, the corrugated tube can not only significantly reduce the temperature difference in tube wall and salt by improving the uniformity of temperature distribution but also enhance the heat transfer of the salt, where the heat transfer coefficient increases with the Reynolds number and heat flux. Moreover, the enhanced effect of the corrugated tube depends on both the pitch and the height of ridges. It is found that the heat transfer coefficient of the salt gets a maximum when the ratio of the height of ridge to the pitch is 0.2. The research presented here may provide guidelines for design optimization of receiver tube in CSP system.

Résumé :

In order to meet the demands of future high-temperature solar thermal power generation, 37 kinds of mixed carbonate molten salts were prepared by mixing potassium carbonate, lithium carbonate, sodium carbonate in accordance with different proportions in this paper. Melting point of molten salt, as the most important basic character, is the primary parameter to select molten salt. Melting point and decomposition temperature are measured by Simultaneous Thermal Analyzer. The results show that melting points of major ternary carbonates are close at around 400°C and decomposition temperatures of most ternary carbonate are between 800 and 850°C. In accordance with energy variation, when the system is cooled from the molten state, precipitates of crystalline phases is orderly. Crystallization temperatures of some samples are much higher than their melting points. Therefore, through comparative experimental study of heating and cooling, 10 kinds of mixed carbonates with low melting point and crystallization temperature were selected primarily. Then, latent heat, density and thermal stability of these mixed salts were studied.
