New method for determining the exchange energy of 2D materials
Jul 09, 2024 (Nanowerk News) Ferromagnetism is an important physical phenomenon that plays a key role in many technologies. It is well-known that metals such as iron, cobalt and nickel are magnetic at room temperature because their electron spins are aligned in parallel — and it is only at very...
Novel strategy to develop high-performance hybrid bio-nanostructures
Jul 08, 2024 (Nanowerk News) The research team of Dr. Jae Ho Kim and Dr. Myungkwan Song from the Energy and Environmental Materials Research Division at the Korea Institute of Materials Science (KIMS) in collaboration with Professor Jin-Woo Oh from Pusan National University and Professor Jin Woo Choi from Kongju...
Micromachines steered by microorganisms
Jul 08, 2024 (Nanowerk News) Researchers have created tiny, vehiclelike structures which can be maneuvered by microscopic algae. The algae are caught in baskets attached to the micromachines, which have been carefully designed to allow them enough room to continue swimming. Two types of vehicles were created: the “rotator,” which...
Principles of origami used to position sensors inside 3D-bioprinted tissues
Jul 08, 2024 (Nanowerk News) Researchers at Tel Aviv University relied on principles of origami, the Japanese art of paperfolding, to develop an original and innovative solution for a problem that has been troubling researchers worldwide: positioning sensors inside 3D-bioprinted tissue models. Instead of bioprinting tissue over the sensors (found...
