Carbonized Sawdust/Barium Titanate as Photothermal Conversion Material for Solar Vapor Generation
Led by Assoc. Prof. Ir. Ts. Dr. Melvin Gan Jet Hong.
Harvesting solar energy for water vapor generation using photothermal conversion materials has received attention by researchers. Diverse materials have been developed to advance photothermal conversion efficiency, such as plasmonic nanoparticles, semiconductors, various carbon materials, and ceramics.
Microporous Membrane in Coalescing Oil from Water
Led by Dr. Chiam Chel Ken.
In this article, we take a closer look at a research on coalescence of oil droplets using microporous membranes. In the case of oil-water emulsion, the separation by using the polymeric microporous membrane behaves differently and molecular sieving mechanism may not be applicable. Oil droplets in water are instable and tend to coalesce to form larger droplets. Contrarily, smaller oil droplets are more stable and the leaning to merge with each other is low.
IoT-Based Portable Biosensor for The Rapid Detection of E. Coli O157:H7
Led by Dr. M.N. Afnan Uda.
Researchers from the Faculty of Engineering at Universiti Malaysia Sabah (UMS) have developed an IoT-based portable biosensor for the rapid detection of E. Coli O157:H7. Ensuring the safety of food is a top global public health priority. Food contamination by pathogens or pollutants poses a significant threat to human health, especially for individuals at higher risk of infection, such as newborns, young children, pregnant women, and the elderly.
Fabrication Process and Characterization of Metal Oxide Semiconductor-Based Sensing Devices
Led by Ts. Dr. Norfarariyanti binti Parimon.
Ts. Dr. Norfarariyanti binti Parimon is a Senior Lecturer in the Electronic Engineering (Computer) Program at the Faculty of Engineering, Universiti Malaysia Sabah (UMS), where she has been serving with UMS since 2010. She completed her Ph.D from Universiti Teknologi MARA in 2021 in Electrical Engineering with a specialization in Material Sciences and Nano-Engineering.
Self-Powered LED System Using Carbon-Based Nanofluid Photothermoelectric Storage
Led by Ts. Dr. Megat Muhammad Ikhsan Bin Megat Hasnan.
In 2022, through HiPER, as advisor to the 3rd year Electric and Electronic Integrated Design Project, Dr Megat had brought his team’s prototype entitled "Self-Powered LED System Using Carbon-Based Nanofluid Photothermoelectric Storage" that presented at International Conference on Advances in Manufacturing and Materials Engineering: ICAMME 2022, 9—10 August, Kuala Lumpur, Malaysia and National Innovation and Invention Competition (NIICe) 2022, 22 August, UTHM, Malaysia and awarded with silver medal.
Nutrient Recovery Through Adsorption Process
Led by Assoc. Prof. Ir. Dr. Abu Zahrim Yaser.
The excessive presence of nutrients, primarily nitrogen and phosphorus, has unleashed a menacing ecological domino effect, igniting algal blooms in many water bodies. These algal blooms, though visually striking, bring darkness to the aquatic world, blocking sunlight and depleting oxygen levels. The far-reaching consequences of this phenomenon have given birth to dead zones - regions marked by alarmingly low oxygen levels, causing the death of marine life and severely impacting fishing industries. A study by Walker in 2019 identified more than 700 coastal areas grappling with these issues. Moreover, some algal blooms produce toxins, posing significant health risks to humans who come into contact with these contaminated waters.
Welcoming a New Young Researcher to The Faculty of Engineering
The Faculty of Engineering is delighted to welcome Dr. Ng Chi Huey to the Oil and Gas Program as a Senior Lecturer at Universiti Malaysia Sabah. After receiving her Ph.D. from Universiti Putra Malaysia and Kyushu Institute of Technology, Dr. Ng worked as a postdoctoral researcher in Japan, where her experience with well-resourced laboratories and cutting-edge technologies helped her develop linkages, scientific discussions, and long-term collaborations with researchers in Japan.
