Abstract:
The purpose of this study was to obtain greater accuracy in the measurement of the heat of reaction by combining data from various thermal analysis techniques. Conventional equations that calculate heat of reaction are limited because they do not take in to account mass change. Therefore, an enhanced equation was developed to integrate mass (weight) change to provide greater accuracy. The path chosen to implement this new equation employed simultaneous Thermogravimetric / Differential Thermal Analysis (TG/DTA) that could provide both ΔT and weight data simultaneously.

Abstract:
Sustainable waste treatment and lignin development strategies targeted for biorefineries will benefit industry, consumers, and the environment. This dissertation demonstrates the feasibility of a novel biochemical pathway capable of converting sugars and lignin sourced from biorefinery waste streams into microbial oils suitable for biodiesel, cosmetic, and biopharmaceutical applications. This biochemical pathway also presents interesting avenues for the commercial production of higher-value intermediate metabolites such as catechol, protocatechuate, pyruvate, and succinate. Alternatively, t

Abstract:
In questo progetto è stata studiata la sintesi di copolimeri a blocchi poli(N-vinil caprolattame)-b-poli(vinil acetato) (PNVCL-b-PVAc) mediante Atom Transfer Radical Polymerization (ATRP). In visione di una futura produzione di questi materiali a livello industriale, è stato ritenuto interessante studiare questo processo utilizzando un solvente con alto valore di flash point, in particolare il polipropilen glicole Mn=1000g/mol (PPG-1000) (flash point 229°C). Inoltre, si è scelto di lavorare a temperature comprese tra 50 e 80°C, in modo da poter asportare il calore di reazione utilizzando sempl

Abstract:
Fundamental studies on thermodynamic properties of vanadium-containing oxides systems are essential to understand practical vanadium metallurgical process. The CALPHAD technique is here applied to the thermodynamic modelling of the V-O, Ca-V-O and Ti-V-O systems. The compound energy formalism is used for all the solution phases. All optimization processes and calculations are performed using the Thermo-Calc software package. The present work attempts to develop a self-consistent thermodynamic database of all phases in the studied systems. The obtained datasets can be used to calculate thermody

Abstract:
Diamonds are commonly present in an ore called kimberlite. Kimberlites vary extensively in mineralogy and therefore can complicate the processing and the extraction of diamonds. Weathering of kimberlite was investigated in this study and refers to the rapid physical breakdown of the kimberlite material. Kimberlite weathering by organic molecule adsorption was investigated utilising organic solutions; ethanol, formamide, n-hexane, oxalic acid, urea, pentanoic acid and acetic acid, was investigated. The extent of weathering was measured by XRD, TGA and FTIR analysis as well as by evaluating chan
