Thermodynamics

The alumina refining industry is one of a number of global industries that produce process waters containing mercury. The research program detailed in this dissertation focuses on processes for removing mercury from Bayer digestion condensate streams. Bayer refinery digestion condensate is chemically unique because it exhibits high pH and is chemically reducing, thermodynamically favouring the presence of elemental mercury.

Studies on nanoparticle-protein interaction have also not been studied. This would give information on ratio influence on the structural alteration of EGCg in EGCg-AuNPs and its functionality in vivo. Herein, the optimisation of EGCg-AuNPs will be determined with a large pool of stoichiometric synthesises of gold and EGCg. These optimised EGCg-AuNPs would then be studied with bovine serum albumin (BSA) for protein interactions, binding and thermodynamics.

We have investigated the thermodynamic properties of the cubic zirconia ZrO2 using the statistical moment method in the statistical physics. The free energy, thermal lattice expansion coefficient, specific heats at the constant volume and those at the constant pressure, CV and CP , are derived in closed analytic forms in terms of the power moments of the atomic displacements.

This work is devoted to the experimental study of a glass/polyester composite laminate under impact shock. Based on a thermodynamic approach, the objective is the evaluation of specific interlaminar delamination energy in a multi-layer composite material under impact loading causing damage to it by cracking.

A clear difference in the enthalpy changes derived from spectroscopic and calorimetric measurements has recently been shown. The exact interpretation of this deviation varied from study to study, but it was generally attributed to the non-two-state transition and heat capacity change. Although the temperature-dependent thermodynamics of the duplex formation was often implied, systemic and extensive studies have been lacking in universally assigning the appropriate thermodynamic parameter sets.

Microcalorimetry and UV-vis spectroscopy were used to conduct thermodynamic and kinetic investigations of the scission of calf thymus DNA catalyzed by bleomycin A5 (BLM-A5) in the presence of ferrous ion and oxygen. The molar reaction enthalpy for the cleavage, the Michaelis– Menten constant for calf thymus DNA and the turnover number of BLM-A5 were calculated by a novel thermokinetic method for an enzyme-catalyzed reaction to be )577 ± 19 kJÆmol)1, 20.4 ± 3.8 lM and 2.28 ± 0.49 · 10)2 s)1, respectively, at 37.0 °C.

A comparative study of thermodynamic and kinetic aspects of Cu(II) and Ni(II) binding at the N-terminal binding site of human and bovine serum albumins (HSA and BSA, respectively) and short peptide analogues was performed using potentiometry and spectroscopic techniques. It was found that while qualitative aspects of interaction (spectra and structures of complexes, order of reactions) could be reproduced, the quantitative parameters (stability and rate constants) could not.

The kinetics and thermodynamics of the urea-induced unfolding of ¯avodoxin and apo¯avodoxin fromDesulfo-vibrio vulgariswere investigated by measuring changes in ¯avin and protein ¯uorescence. The reaction of urea with ¯avodoxin is up to 5000 times slower than the reaction with the apoprotein (0.67 s )1 in 3 Murea in 25 mMsodium phosphate at 25°C), and it results in the dissociation of FMN.

Ikkai&Ooi [Ikkai,T.&Ooi,T. (1966)Biochemistry5, 1551± 1560] made a thorough study of the e€ect of pressure on G- and F-actins. However, all of the measurements in their study were made after the release of pressure. In the present experiment in situ observations were attempted by using eATP to obtain further detailed kinetic and thermodynamic information about the behaviour of actin under pressure.

The proposed biological function ofb-lactoglobulins as transporting proteins assumes a binding ability for ligands andhighstabilityunder theacidic conditionsof the stomach. This work shows that the conformational stability of non-ruminant porcine b-lactoglobulin (BLG) is not consistent with this hypothesis. Thermal denaturation of porcine BLG was studied by high-sensitivity differential scanning calori-metry within the pH range 2.0–10.0.
