Abstract:
Abstract. Dicarboxylic acids likely participate in the formation of pre-nucleation clusters to facilitate new particle formation in the atmosphere, but the detailed mechanism leading to the formation of multicomponent critical nuclei involving organic acids, sulfuric acid (SA), base species, and water remains unclear. In this study, theoretical calculations are performed to elucidate the interactions between succinic acid (SUA) and clusters consisting of SA-ammonia (AM)∕dimethylamine (DMA) in the presence of hydration of up to six water molecules. Formation of the hydrated SUA⚫SA⚫ base clusters is energetically favorable, triggering proton transfer from SA to the base molecule to form new covalent bonds or strengthening the preexisting covalent bonds. The presence of SUA promotes hydration of the SA⚫AM and SA⚫AM⚫DMA clusters but dehydration of the SA⚫DMA clusters. At equilibrium, SUA competes with the second SA molecule for addition to the SA⚫ base clusters at atmospherically relevant concentrations. The clusters containing both the base and organic acid are capable of further binding with acid molecules to promote subsequent growth. Our results indicate that the multicomponent nucleation involving organic acids, sulfuric acid, and base species promotes new particle formation in the atmosphere, particularly under polluted conditions with a high concentration of diverse organic acids.

Abstract:
This review discusses the changes in acid–base balance that are produced during hypometabolism and the negative feedback role they play in maintaining the hypometabolic state. In prolonged hypometabolism, air-breathing animals consume internal stores of fat, protein, and carbohydrate, while glycogen is the primary fuel supporting anaerobic hypometabolism. Because the excretory processes are greatly reduced, the accumulation of waste products must be dealt with internally. Mitigating strategies to minimise acid–base disturbance are seen in higher buffer capacities, an acid shift in the pH optima of key enzymes, and the use of metabolic pathways that result in a reduction of net H+ production. In some hibernating animals, gut bacteria may play an important role in preventing [Formula: see text] accumulation. However, the compensatory mechanisms are only partially successful, and substantial alterations in acid–base status and related strong ion changes are common. Changes in intracellular pH have wide metabolic effects but the acid–base and ionic status of the cell is dependent on its energy expenditure. The most vulnerable tissue to reduced metabolism is the brain. The turtle brain can greatly lessen its energy requirements by reducing activity; this is achieved by (i) depression of synaptic transmission, (ii) membrane hyperpolarisation through opening of Cl− channels resulting from release of γ-aminobutyric acid, and (iii) slowing transmembrane ion flux by the selective closure of ion channels. CO2 retention is common in hypometabolic animals. Increased levels of CO2 and H+ and decreased [Formula: see text] can directly cause metabolic depression via a variety of mechanisms, as well as a reduction in neural tissue activity. It is concluded that the hypometabolic state represents a very general condition of temporarily reduced energy expenditure which embraces aestivation, hibernation, torpor, and sleep, and that the common phenomena of CO2 accumulation and consequent changes in acid–base balance play a role in the coordinated reductions in energy expenditure and energy cost.

Abstract:
Acid/Base characterizations of metal oxide surfaces are often used to explain their catalytic behavior. However, the vast majority of these studies have been performed on powders or supported oxides, and there is very little information available in the literature on the interaction of acid/base probe molecules with well-defined oxide surfaces of known coordination geometry and oxidation state. The well-defined, single crystal surfaces of Cu2O (111), SnO2 (110), and Cr2O3 (1012) were investigated for their acid/base properties by the interactions between the probe molecules and the well-defined surface features. The adsorption of NH3 at cation sites was used to characterize the Lewis acidity of SnO2 (110) and Cu2O (111) surfaces. The adsorption of CO2, a standard acidic probe molecule, was used to characterize the Lewis basicity of the oxygen anions on SnO2 (110), Cu2O (111) , and Cr2O3 (1012) surfaces. BF3, while not a standard probe molecule, has been tested as a probe of the Lewis basicity of the oxygen anions on SnO2 (110) and Cr2O3 (1012). By studying probe molecules on well-defined metal oxide surfaces with known coordination geometry and oxidation state, an overall evaluation of NH3, CO2, and BF3 as probe molecules can be made using the surfaces studied. NH3 probed differences in Lewis acidity of Sn cations on SnO2 (110), which had differences in coordination environments and oxidation states. But, NH3 adsorption failed to provide any direct information on differences in Lewis acidity of Cu cations in different local coordination geometries on Cu2O (111). CO2 is a poor probe of the Lewis basicity of oxygen anions on the metal oxide surfaces studied here. CO2 does not strongly adsorb to either SnO2 (110) or Cu2O (111). On Cr2O3 (1012), CO2 does interact with oxygen sites but in two different coordinations, which vary with surface condition, making a comparison of basicity difficult. In the cases studied here, CO2 either does not adsorb, or it does not provide a clear set of results that can be related simply to Lewis basicity. BF3 seems to be a much better probe of the Lewis basicity than CO2 for the well-defined metal oxide surfaces studied here. On SnO2 (110) and Cr2O3 (1012), the boron atom of BF3 directly interacts with oxygen sites by accepting their electrons. BF3 thermal desorption seems to provide a direct measure of the Lewis basicity of different surface oxygen species as long as they are thermally-stable in vacuum.

Abstract:
The phase behavior of CO2 + polymer systems is of interest in polymer synthesis, flue and natural gas processing, polymer foam and nanoparticle processing, and drug delivery. Theoretical and experimental evidence suggests that CO2 is able to interact with electron donating functional groups in polymers to form weak Lewis acid – base or EDA (Electron Donor Acceptor) complexes. These complexes can have a significant effect on the phase behavior of associated CO2 + polymer systems. In spite of this, however, the phase equilibria of only a few associated CO2 + polymer systems have been measured. Some success in modeling the phase behavior of polymer solutions has been achieved by various versions of the Statistical Association Fluid Theory (SAFT), as well as by several Lattice Models. However, many of these models incorporate two to four adjustable parameters that often depend on temperature (T), pressure (P), and/or molecular weight (MW). As a result, a large amount of experimental data is required to apply these models. The goal of the present work was therefore to develop a new thermodynamic model for associating systems that would include no more than two temperature-independent adjustable parameters. The new model presented in this work is based on the Guggenheim-Huggins-Miller lattice and includes complex formation in the development of the partition function. The EOS obtained from the resulting partition function includes two mixture parameters – the enthalpy of association or complex formation and a reference value of the equilibrium constant for complex formation . Most importantly, can be obtained from in situ Attenuated Total Reflection Fourier Transform Infrared (ATR – FTIR) measurements. This work therefore demonstrates the use of ATR – FTIR spectra to obtain molecular level information regarding the interaction of CO2 and electron donating functional groups in polymers. Unlike other studies, this work uses the bending vibration of CO2 to estimate the enthalpies of association ( ) of CO2 + polymer systems. Values of were directly incorporated in the new model and were found to lie between -7 and -12 kJ/mol for the systems investigated in this work. They increased (i.e. became more negative) in the order: CO2 + PS-co-PMMA < CO2 + PMMA

Full text
Abstract:
This thesis deals with secondary interactions in asymmetric catalysis and their impact on the outcome of catalytic reactions. The first part revolves around the metal-catalyzed asymmetric allylic alkylation reaction and how interactions within the catalyst affect the stereochemistry. An OH–Pd hydrogen bond in Pd(0)–π-olefin complexes of hydroxy-containing oxazoline ligands was identified by density functional theory computations and helped to rationalize the contrasting results obtained employing hydroxy- and methoxy-containing ligands in the catalytic reaction. This type of hydrogen bond was further studied in phenanthroline metal complexes. As expected for a hydrogen bond, the strength of the bond was found to increase with increased electron density at the metal and with increased acidity of the hydroxy protons. The second part deals with the use of hydroxy- and methoxy-containing phosphinooxazoline ligands in the rhodium- and iridium-catalyzed asymmetric hydrosilylation reaction. The enantioselectivities obtained were profoundly enhanced upon the addition of silver salts. This phenomenon was explained by an oxygen–metal coordination in the catalytic complexes, which was confirmed by NMR studies of an iridium complex. Interestingly, the rhodium and iridium catalysts nearly serve as pseudo-enantiomers giving products with different absolute configurations. The final part deals with ditopic pyridinobisoxazoline ligands and the application of their metal complexes in asymmetric cyanation reactions. Upon complexation, these ligands provide catalysts with both Lewis acidic and Lewis basic sites, capable of activating both the substrate and the cyanation reagent. Lanthanide and aluminum complexes of these ligands were found to catalyze the addition of the fairly unreactive cyanation reagents ethyl cyanoformate and acetyl cyanide to benzaldehyde, whereas complexes of ligands lacking the Lewis basic coordination sites failed to do so.

Abstract:
The fundamental study of Lewis acid/base interactions presented in this dissertation demonstrates the role of these interactions in adhesive phenomena. The model systems investigated were representative of real substrates and soft, viscoelastic adhesives where, in one case, favorable acid/base interactions were possible which were not possible in the other. Inverse gas chromatography (IGC) and Infrared spectroscopy (IR) techniques were used to analyze the model adhesive in terms of its acid/base nature. The results of both experiments indicated, through negative enthalpies of acid/base interaction with acidic solvents, that the model adhesive poly(2-ethyl hexyl methacrylate) (PEHMA) exhibits the properties of a Lewis base. The near quantitative agreement of the results from both experiments validate these methods of determining acid/base interactions in polymeric systems. Fitting the enthalpies for acid/base interaction to Drago’s and Gutmann’s models brought out the importance of the electrostatic component of the interactions investigated. Furthermore, they illustrated the need to expand the existing datasets beyond organo-meta1lic compounds, and include more common organic solvents. Results from X-ray photoelectron spectroscopy (XPS) and scanning transmission electron microscopy (STEM) analysis of the model substrate, grade 2 titanium, pretreated via chromic acid (CAA) or sodium hydroxide anodization (PSHA), confirmed that oxides of very similar topology can be produced. Indicator dye studies revealed the CAA-Ti had a surface pH of below 3.0 and the PSHA-Ti had a surface pH of above 8.0. Bonds constructed from these analyzed materials were tested in peel and both systems exhibited good adhesion. However, the bonds in which favorable interactions were possible demonstrated superior interfacial performance. This improvement was seen in the bond’s ability to resist adhesive (interfacial) failure at debond rates at which other bonds failed. When the test geometry was changed such that the stress intensity at the interface was increased, the bonds in which acid/base interactions were favorable supported a higher peel load.

Abstract:
When two or more drugs are administered simultaneously, the pharmacological response may be greater or less than the sum of the effects of the individual drugs. One drug may antagonize or potentiate the effects of the other and there may be also qualitative differences in response. Although some drug interactions increase the toxicity or result in loss of therapeutic effect, others are beneficial. Indeed, modern anaesthetic techniques depend on beneficial drug interactions. A sound combination of drugs helps clinicians to increase both the efficacy and safety of drug treatment. Drugs may interact on a pharmaceutical, pharmacodynamic, or pharmacokinetic basis. Many pharmacodynamic interactions are predictable and can be avoided by the use of common sense. However, it is much more difficult to predict the likelihood of pharmacokinetic and pharmaceutical interactions despite good prior knowledge of pharmacokinetics and chemical properties of individual drugs. Pharmaceutical drug interactions usually occur before the drug is given to the patient and they are caused by chemical (such as acid–base, salt formation, oxidation–reduction, hydrolysis, or epimerization) or physical (such as adsorption/absorption or emulsion breaking) reactions. When drugs have a pharmacokinetic interaction, one drug alters the absorption, distribution, or the elimination of the other drug. Many pharmacokinetic drug interactions are due to inhibition or induction of cytochrome P450 enzymes. Pharmacodynamic drug interactions are caused by drugs having an effect on the same receptors or the same physiological system. This chapter gives anaesthetists an overview of clinically relevant perioperative drug interactions.

Abstract:
Surface free energy of composite and coatings are critically important for the performance of the materials since the change in surface free energies can drastically affect the physical, chemical and physicochemical properties, and hence the service life of them. The characterization of the surface free energy is the key issue to understand the mechanisms of the surface degradation. Acid-base interaction is one way of determining the surface free energy change on these surfaces. In the present study, we exposed composite and coating surfaces to UV light, and then measured the contact angle values using various liquids (e.g., DI water, diiodomethane and glycerol). Using the van Oss approach, we calculated the surface energy changes of the surfaces exposed to the UV light. We found that the surface energy, acidity and basicity of the composite and coating materials were drastically changed as a function of UV exposure time. This study can be useful for the moisture uptake of composites, composite degradation, aging and service life of these products.

Full text
Abstract:
The reliability and performance of a gas turbine compressor is strongly dependent upon the environment in which it operates, the materials which are used, and the filtration system. Erosion and to a certain extent fouling can be controlled by the filtration system, but corrosion is largely controlled through site and material selection. The factors which determine the corrosivity of a site are humidity, the concentration of acid-forming gases, and the composition of particulates. The interrelationships of these factors are discussed with an aim of reducing their impact on compressor operation. A necessary condition for corrosion is the presence of moisture. The acidity of the moisture results from its interaction with the gases and particulates of the environment. The details of these interactions which are important to turbine operators are discussed. A considerable amount of corrosion testing of base materials and coatings has been performed and this is reviewed. A table is presented for selection of compressor materials based on the nature of the site environment and the type of compressor filtration.

Abstract:
"Water treatment technologies involving pre-treated industrial effluents without transporting them to the tailing dump are of interest primarily from an environmental point of view, as they reduce the environmental burden. The paper studies the possibility of purification of process waters from apatite concentrate production from suspended particles and water-soluble impurities using polyacrylamide flocculants. By studying the processes of adsorption of H+ and OH- ions from aqueous solutions, the acid-base properties of the surface of the solid phase of the most polluted technological product - the drain of the apatite concentrate thickener - the mineral composition of which is 90% apatite have been studied. The influence of the reagents present in the processing technology on the quantitative ratio of acid-base centres on the apatite surface has been evaluated. It has been shown that the interaction of these reagents with the mineral creates prerequisites for a greater efficiency of the anionic flocculant. The electro-surface properties of apatite treated with various reagents were studied using the laser Doppler electrophoresis method. The mechanism of fixation of ions present in the dispersion medium on the surface of apatite was studied by infrared spectroscopy. In order to determine the conditions under which various flocculants are in the most ionized state, studies were conducted on the change in the viscosity of the polyelectrolyte solution at different pH values. The position of the isoionic point for samples of cationic and anionic flocculants in the presence of reagents used in the apatite flotation and dehydration of apatite concentrate was studied. A research has been carried out on ""model"" and real suspensions in circulating water for a number of cationic, anionic and nonionic flocculants. The kinetic and concentration dependences of the flocculating capacity of the studied reagents were determined, which confirmed the high efficiency of the anionic type reagents"

Abstract:
In the final step of protein C pathway, activated protein C (APC) is neutralized with a plasma inhibitor, termed protein C inhibitor (PCI). PCI was first described by Marlar and Griffin (1980) and then isolated from human plasma as a homogeneous form and characterized by the authors (1983). PCI is a single chain glycoprotein with M 57,000 and a plasma concentration of 5 ug/ml. Analysis of a cDNA nucleotide sequence has clarified that a precursor of human PCI consists of a mature protein of 387 amino acid residues (M 43,759) and a signal peptide of 19 amino acid residues. Only one cysteine residue is present in the entire protein as in α1antitrypsin (α1AT) and α1antichymotrypsin (α1ACT). Three Asn-X-Ser/Thr sequences and two Ser/Thr-X-X-Pro sequences are present as potential attachment sites of carbohydrate chains. Based on the amino acid sequence of the carboxyl-terminal peptide released from the inhibitor by APC digestion, the reactive site peptide bond of PCI was found to be Arg(354)-Ser(355). It is similar to the reactive sites of the other serine protease inhibitors which are located to their carboxyl-terminal Arg(393)-Ser (394), Met(358)-Ser(359) and Leu(358)-Ser(359) in antithrombin III, α1AT and α1ACT, respectively. The alignment of the amino acid sequence of PCI with heparin cofactor II, α1plasmin inhibitor, ovalbumin, angiotensinogen and the above noted plasma inhibitors showed that PCI is a member of serine protease inhibitor superfamily. PCI inhibits APC noncompetitively in a 1:1 stoichiometry and forms a covalent acyl-bond with a Ser residue in the active center of APC. The half life of APC in plasma approximately 30 min, which is rather slow compared with the other protease inhibitors. However, optimal concentrations of heparin, dextran sulfate and its derivatives potentiate the rate of inhibition 30-60 fold. PCI has Ki of 10-8m for APC, and can inhibit thrombin, Factor Xa, urokinase and tissue plasminogen activator as well in the presence of heparin or dextran sulfate, though the Ki for these enzymes is slightly higher. During the complex formation with APC, PCI is cleaved by the complexed APC to form a modified form with M 54,000. PCI is synthesized in several hepatoma cell lines and decreased in plasma of patients with liver cirrhosis. It is also decreased in patients with DIC or those during cardiopulmonary bypass in parallel with the decrease in protein C, suggesting that PCI participates in regulation of the protein C pathway in intravascular coagulation. Recently, we have obtained the recombinant PCI from COS-1 cells which were transfected with expression vector pSV2 containing the cDNA of PCI. The recombinant PCI had the same Mr and specific activity as the protein purified from plasma. It also had an affinity for heparin and dextran sulfate. Moreover, we have predicted a three dimentional structure of the proteolytically modified PCI with computer graphics based on its amino acid sequence homology with the modified α1AT whose structure had been elucidated with X-ray crystallography. All potential carbohydrate attachment sites were estimated to exist on the surface of the protein. Succesively we have constructed the interaction model between the intact PCI predicted from the modified form and the active center of APC which was simulated from that of trypsin. From the model, it was observed that the amino-group of Arg (354, PI site) of PCI could strongly interact with the carboxy1-group of Asp (88, SI site) of the heavy chain of APC at the base of the active center pocket of the enzyme.

Abstract:
Abstract Surfactant selection is important for oil recovery in a hydraulically fractured reservoir. Two primary mechanisms, ion-pair coupling (cleaning) between surfactant and hydrocarbon and surfactant adsorption onto the rock surface (coating), were previously suggested to explain how surfactants can alter rock wettability, thus improving oil production. Because of the electrostatic interaction, acidic compounds in the oil tend to be adsorbed onto rock surface that is positively charged; whereas basic compounds are preferentially attracted to rock surface that is negatively charged. It has been discussed in previous literature that for wettability alteration for conventional formation rocks, the cleaning mechanism could be more efficient by inducing ion pairs between surfactants and oil compounds that have opposite charges, rather than the coating mechanism that mainly relies on how well surfactant covers the rock surface. In this research, 90 shale oils from various liquids shale plays, such as the Eagle Ford and the Wolfcamp, were tested for total acid number (TAN) and total base number (TBN). Cationic and anionic surfactants with low interfacial surface tension, along with Berea sandstone and Indiana limestone, were used to investigate the extent that TAN and TBN can be used as criteria to select surfactants. Oil recovery, imbibition, interfacial surface tension, and emulsion tendency were conducted to examine whether the cleaning mechanism holds true for shale oil saturated formation rocks. The results demonstrated that for carbonates with shale oil having a higher TAN, a cationic surfactant provided the potential to sweep more oil than an anionic surfactant. On the other hand, for sandstone with shale oil having a higher TBN, an anionic surfactant performed better than a cationic surfactant. Those observations appear to be consistent with the proposed cleaning mechanism and resonate with production data for thousands of wells from some major liquids-rich shale plays.
