The effect of impurities in black liquor-derived carbonaceous compound on direct carbon fuel cell performance

This project aims to investigate the effect of silica on the carbonecous compound derived from black liquor in two aspects: the characteristic of the biochar produced and the electrical performance in direct carbon fuel cell (DCFC)

Partial purification of Bacillus subtilis Xylanase using Aqueous Two-Phase System

The present project will focus on the partial purification of Bacillus subtilis xylanase from the fermentation broth using polymer-salt aqueous two-phase system (ATPS) integrated with electrophoresis. Several ATPS parameters are investigated to determine the optimum parameters which lead to the highest xylanase yield and purity.

Optimisation of α-pinene from Eucalyptus deglupta through hybrid drying of ultrasound assisted osmotic dehydration (UOAD) and hot-air drying

The present project will be focusing on optimizing the parameters of UOAD pre-treatment conditions to achieve a highest yield of α-pinene, total phenolic content (TPC), antioxidant and anti-inflammatory activity through response surface methodology (RSM).

Investigation of optimum condition to cultivate dry bacteria for wastewater treatment purpose

This project is aim to reduce the maintenance cost of biological wastewater treatment by reducing the interval of dry bacteria addition into the treatment system. The optimum condition to cultivate dry bacteria is first investigated. The condition will be tested for the stability of treatment system using raw food wastewate.

Waste water treatment using Moringa oleifera: Drying, extraction and response surface methodology optimisation studies

This project will be focused on the impact of hot air drying temperatures and solid to solvent ratios to the preparation of the Moringa oleifera seeds as the natural coagulant to treat dye wastewater.

Synthesise a sustainable bioenergy supply chain

The objective of this research work is to develop a novel mathematical approach to synthesize an optimum and sustainable bioelectricity supply chain for palm oil plant. This novel approach helps in decision making in selecting the processes, technologies and its equipment for an optimum palm oil- based bioelectricity supply chain.

Evaluation of boron removal by coagulation process

This research aims to investigate boron removal efficiency using natural and chemical coagulants. The economic performance index will be studied for various coagulants to identify the most sustainable coagulants for boron removal.
