Thermoelectric devices are promising for capturing and converting waste heat it into useful electricity. Conventional devices mainly rely on longitudinal thermopower generation. However, these devices consist of stacked layers of semiconductors, whose contact interfaces increase electrical resistance, reducing efficiency. In a new study, researchers discovered a new candidate material, MoSi₂, for transverse thermoelectric devices that are significantly more efficient.

Graphene is a promising material for gas separation. However, identifying the optimal pore sizes for efficiently filtering different gases remains a challenge. Researchers at Chiba University have found that strategically adding oxygen to graphene improves its ability to separate carbon dioxide from methane while still allowing gases to flow through quickly, a critical requirement for industrial use. This approach could enable real-world applications of graphene membranes as a more energy-efficient technology for gas purification.

A novel water-based gel, also known as a hydrogel, not only fights bacteria but also calms inflammation, thereby actively supporting wound healing.

The material functions like a net, catching bacteria and then killing them when triggered by a light pulse.

The gel has proven highly effective against the antibiotic-resistant MRSA bacteria in animal models while also accelerating wound healing.

Nanyang Technological University, Singapore (NTU Singapore) has unveiled Singapore’s first locally designed and built full-sized aircraft, an advanced electric vertical take-off and landing (eVTOL) technology demonstrator. This eight-metre wingspan homegrown aircraft prototype, developed over more than three years by researchers and engineers from NTU Singapore, marks a significant milestone in Singapore’s aerospace research capabilities.

Eight lift rotors powered by NTU-designed electric motors are mounted on the wings to enable vertical take-off and landing from any confined space. Once airborne, the proprotor at the back quietly propels the aircraft forward, allowing it to fly like a normal airplane. It was unveiled today at the Singapore Airshow 2026 by NTU Vice President (Industry) Professor Lam Khin Yong, together with other industry partners.
