In this research, Molecular Dynamics (MD) simulations were conducted to explore the temperature effect on the microstructure and phase transition of the Ag0.25Au0.75 alloy. The findings reveal that as the temperature rises, the material's phase transition switches from crystalline to liquid and vice versa.

Resting egg production of rotifers provides critical advantages in larviculture of most fish species due to the reduction in the costs of labour and algae production. The study was conducted to investigate the effects of temperature on population growth and resting egg production of a freshwater rotifer, Brachionus calyciflorus, collected in Northern Vietnam.

Land use and land cover (LULC) change is a key factor influencing land surface temperature (LST) dynamics. This change reflects partly global warming and climate change at local and regional scales. This study aimed to evaluate the effect of LULC on LST change in Lac Duong mountainous district, Lam Dong province in the past 10 years (2013 - 2023), and predict the LST change in 2030.

In this thesis, a numerical model with detailed reaction mechanism which is tailored for studying the behaviour of combustion of natural gas has been introduced and validated with available experimental data. The numerical model attempts to comprehensively simulate the physical conditions (temperature and pressure), equivalent ratio, and fuel dilution and strain rate effect in the laminar flames.

The proposed research aims to investigate the influences of temperature on the water retention behaviour of deformable unsaturated soil. Volume change caused by temperature variation will be taken into consideration. This research will produce a better understanding and interpretation of thermal effects on SWCCs by providing experimental results for deformable unsaturated soils.

Municipal wastewater treatment plants generally utilise biological activated sludge processes to remove organic compounds and nitrogen. The biological nitrogen removal (BNR) occurs in two steps, nitrification (ammonium removal) and denitrification (nitrates removal). This study focused on a medium-sized wastewater treatment plant (WTP) which experienced poor nitrification for years, mainly when the weather temperature drops.

This thesis has two key results, a study on the effect of carbon in electron-beam deposited platinum nano-wires and a novel temperature sensing glass substrate for marker-free thermometry. The thesis focus on the effect of carbon contamination in plasmonic nano-wires composed mainly of platinum produced from FEBID. Because carbon acts as an insulator in the platinum/carbon composite, we model the effect of carbon impurities by reducing the charge carrier concentration inthe platinumwire.

The main aim of this investigation was to develop a low-cost solution to remove trace metals from the aqueous phase using biochar. This study investigated (i) the effect of giant reed-based biochar produced at varying temperatures in the treatment of aqueous solutions polluted with lead; and (ii) how the production of biochar at different temperatures affected its adsorption capacity for lead from the aqueous phase.

Thermostable and highly water-soluble polymers are essential for polymer flooding — one of the most effective methods used in the enhanced oil recovery (EOR) in hightemperature (HT) offshore reservoirs. In this research, the copolymerization reaction of acrylamide (AM) and N-vinylpyrrolidone (NVP) monomers were performed via a freeradical mechanism induced by gamma-rays (γ-rays) irradiation.
