Uncovering the secrets behind the silent flight of owls
From Chiba University 25/01/24 Owls are fascinating creatures that can fly silently through some of the quietest places. Their wings make no noise while flying, enabling them to accurately locate their prey using their exceptional hearing ability while remaining undetected. This unique ability depends on many factors and has long been a hot research subject. […]
Perfecting 3D-printed blood vessels with pores
From Pohang University of Science & Technology (POSTECH) 24/01/24 Due to the substantial clinical demand for artificial small-diameter vessels (SDVs), numerous commercial products have emerged. However, the majority of existing artificial SDVs lack an endothelial layer, leading to thrombosis. Fabricating artificial SDVs with a consistently uniform endothelial layer and adequate mechanical properties has proven exceptionally […]
Pushing the boundaries of ultrasound imaging: breaking new ground with ultrafast technology
From Pohang University of Science & Technology (POSTECH) 23/01/24 Recently, high-speed video content capturing fleeting moments, such as bullets passing through glass, has captured people’s interest. What if we implement ultrasound used in medical examinations into high-speed video? A research team at POSTECH (Pohang University of Science and Technology) has solved the mystery of kidney […]
Korean Artificial Sun, KSTAR, installation of a tungsten divertor for long pulse operations
From National Research Council of Science & Technology 03/01/24 The Korean artificial sun, KSTAR, has completed divertor upgrades, allowing it to operate for extended periods sustaining high-temperature plasma over the 100 million degrees. The Korea Institute of Fusion Energy announced the successful installation of the newly developed tungsten divertor for KSTAR. KSTAR, now equipped with […]
KERI’s metamaterial, stretchable and efficient wearable thermoelectric energy harvester!
From National Research Council of Science & Technology 29/11/23 A team of Dr. Hyekyoung Choi and Min Ju Yun from Korea Electrotechnology Research Institute (KERI) has developed advanced thermoelectric generator technology. This technology uses ‘mechanical metamaterials’, which are artificially designed materials not found in nature. Usually, materials shrink vertically when stretched horizontally, like a rubber […]
Harvesting solar heat and raindrop energy using non-planar dielectrics
From Science China Press 22/11/23 This study is led by Prof. Jiaqing He (Southern University of Science and Technology) and Prof. Ghim Wei Ho (National University of Singapore). Weather-dependent environmental energy harvesting of solar heat, wind energy, and rain energy towards carbon sustainability and net zero is critical in the post-pandemic world, where economic activities […]
Enlightening insects: Morpho butterfly nanostructure inspires technology for bright, balanced lighting
From Osaka University 01/11/23 As you watch Morpho butterflies wobble in flight, shimmering in vivid blue color, you’re witnessing an uncommon form of structural color that researchers are only beginning to use in lighting technologies such as optical diffusers. Furthermore, imparting a self-cleaning capability to such diffusers would minimize soiling and staining and maximize practical […]
New technology for customized air purification of toxic gases
From National Research Council of Science & Technology 03/11/23 Volatile organic compounds (VOCs) in daily products such as paints, adhesives, furniture, cosmetics, and deodorants make our lives easier. However, constant exposure can cause serious health problems such as respiratory illness, headaches, dermatitis, and cancer. Natural ventilation is the most effective way to reduce VOCs in […]
