1. This article details the design of a microdirect methanol fuel cell, which includes silicon substrate-based electrode flow field plates that were microfabricated using micro-electro-mechanical system (MEMS) technology.
2. This article examines the antimicrobial properties of shellac coatings infused with citrus fruit waste and used cooking oil (UCO).
3. This article investigates the relationship between the Air Pollution Index (API) and meteorological factors, such as wind speed and direction, during haze episodes in East Malaysia.
4. This article investigates the presence of heavy metals in cosmetic products in the Malaysian market, raising concerns about the potential health risks posed by these contaminants.
5. This article investigates the antibacterial properties of quaternized chitosan/PVA films enhanced by the addition of tetraethyl orthosilicate (TEOS).
6. This article describes a study that optimized the process of producing carbon nanotubes (CNTs) from sewage sludge by determining that a catalyst loading of 0.5 and a temperature of 800 ˚C resulted in the maximum yield of CNTs.
7. This article investigates the potential of orange peels as a biosorbent for removing crude oil from contaminated water through batch adsorption tests and optimization using response surface methodology (RSM) and SigmaXL software.
8. This article examines the potential risks associated with accidental chemical releases from two bioethanol production plants in Selangor, Malaysia, using quantitative accident analysis and software simulations to determine the impact on human fatalities.
9. This article describes a method for extracting cellulose nanofibers from Semantan bamboo using a chemical treatment involving nitric acid and hydrogen peroxide, and it identifies the optimal conditions for achieving the highest yield of nanofibers.
10. This article reviews how using finite element analysis (FEA) as a tool can improve the performance of proton exchange membrane fuel cells (PEMFCs)
