Prevention of unforeseen and sudden accidents within our immediate environment as a result of gaseous pollutants and /or gas cylinder leakage make it necessary for researchers and industrialist across the world to provide effective means for present and future prevention through fabrication of gas sensors. Semiconductor metal oxide gas sensors have been proven to be the most efficient gas sensors exploited so for due to a number of reasons such as simplicity in their fabrication and cost effective.
Theoretical study always help to understand the more sciences. This modelling and simulation study is to explore the behavior of pristine and different doped metal oxide clusters in the presence of gas molecules. The results may help to understand the mechanism of sensitivity and reactivity improvements in the gas sensors which will be useful for the experimental works. Energy calculations, geometry optimizations, density of states (DOS), and natural bond orbital analyses are some of selected simulation works.
Waste generated as by product from many factories. Zinc, copper, nickel, lead and toxic dye contaminated wastewater has been a major concern due to its extremely hazardous impact on the environment and human health. Adsorption method have been proven to be most effective and low-cost technique for treating the contaminated wastewater. Modified and development of activated carbon with waste biomass as its precursor are considered as an excellent adsorbent for removal of the contaminants due to its cost effective and high adsorption capacity.
The aim of this applied-research project is to develop and demonstrate coatings for application in maritime-building infrastructure. There are three types of coatings to be developed and demonstrated: antifungal, anticorrosion and concrete-protection. There are three main activities for this project. The initial research and development activity will take place at the Centre for Advanced Material and Energy Sciences (CAMES), under the host organisation, Universiti Brunei Darussalam (UBD). The latter demonstration activity will be conducted in collaboration with the Centre of Science and Technology, Research and Development (CSTRAD) on maritime-building assets belonging to the Ministry of Defence Brunei Darussalam. The final activity involves filing the patent applications related to these coating products. Laboratory skills and knowledge related to undergraduate Chemistry and/or Physics are required.

The aim of this project is to synthesize functionalized zeolites catalyst for methane activation reaction. The activation of methane enables the direct conversion of methane (a major component of natural gas) into higher monetary value chemicals such as alcohols, syngas, alkenes, alkynes and aromatics, a reaction regarded as the “holy grail” in the chemical industry. Zeolite comprises of a crystalline framework of aluminosilicates and because of its high porosity and reactive acidic sites, zeolites has shown to have exceptional performance as catalyst in various reactions in the chemical industry. The active sites can be chemically modified to enhance its catalytic performance, thus to functionalise the catalyst. The world market demand for zeolites catalyst is USD20 billion in and it is projected to grow to USD24 billion by 2018.
Heterogeneous catalysis technology is the key for green energy. It is involved in making petrochemical processes more efficient and also the development of renewable energy such as water splitting and solar photovoltaic cells. Metal oxides are usually used as materials for heterogeneous catalysis. Since most of the catalytic reactions occurs on the surface, surface chemistry and optimisation is utmost important. One method to optimise the surfaces of the metal oxide catalyst is by specifying its exposed facets, and this can be achieved by tuning the morphology of the metal oxides. However, this method of optimisation is not feasible for the chemical industry due to the complication and high cost of synthesising these morphology-controlled oxide catalysts. This project aims to develop facile and cost effective synthesis methods, so the catalysed chemical processes can be more efficient and economical.
Hybrid plasmonic nanostructures (HPNs) are a combination of structured metal and dielectric materials in the nanoscale. HPNs possess special optical and electrical effects which are applicable to the diverse applications on water purification and other nanophotonic devices, such as nanoantennas and bio-sensors. The water purification technology will compliment existing water treatment technologies where the HPNs based water purification technology is targeted for the treatment of industrial waste water containing organic compounds, metals, and micro-organisms. In this project, the investigated HPNs will be performed by using the simulation and experiment methods simultaneously.
