The first eco-friendly fluorescent artificial seed for monitoring soil temperature by using drones
Nov 21, 2023 (Nanowerk News) A new kind of artificial seed to sense environmental parameters without impacting on the health of environment is the invention coming from the IIT-Istituto Italiano di Tecnologia (Italian Institute of Technology) in Genova, Italy. The soft robot, named Acer i-Seed, is inspired by natural Acer...
New strategy could revolutionize the design and development of proton conductors
Nov 21, 2023 (Nanowerk News) Donor doping into a mother material with disordered intrinsic oxygen vacancies, instead of the widely used strategy of acceptor doping into a material without oxygen vacancies, can greatly enhance the conductivity and stability of perovskite-type proton conductors at intermediate and low temperatures of 250–400 °C,...
Infection-resistant, 3D-printed metals developed for implants
Nov 20, 2023 (Nanowerk News) A novel surgical implant developed by Washington State University researchers was able to kill 87% of the bacteria that cause staph infections in laboratory tests, while remaining strong and compatible with surrounding tissue like current implants. The work, reported in the International Journal of Extreme...
State-of-the-art nanomaterial enables ecofriendly removal of fine dust precursors
Nov 20, 2023 (Nanowerk News) Over the past decade, fine dust conditions in Korea have worsened, as perceived by the general public, with an increase in the number of days per year featuring high-concentration fine dust. Additionally, the previous maximum fine-dust concentration level has been surpassed. In response, the Korean...
Discovery of structural regularity hidden in silica glass
Nov 21, 2023 (Nanowerk News) Glass - whether used to insulate our homes or as the screens in our computers and smartphones - is a fundamental material. Yet, despite its long usage throughout human history, the disordered structure of its atomic configuration still baffles scientists, making understanding and controlling its...
Nano-sized probes reveal how cellular structure responds to pressure
Nov 20, 2023 (Nanowerk News) By giving living cells a ‘nano-poke’ and monitoring the resulting changes in the intra-cellular environment, researchers have gotten their first glimpse of how whole cells respond to external mechanical pressure. A team lead by scientists from the National Institute for Materials Science in Tsukuba, Japan,...
Physicists answer question of Supergalactic Plane’s absent spiral galaxies
Nov 20, 2023 (Nanowerk News) Astrophysicists say they have found an answer to why spiral galaxies like our own Milky Way are largely missing from a part of our Local Universe called the Supergalactic Plane. The Supergalactic Plane is an enormous, flattened structure extending nearly a billion light years across...
AI system self-organizes to develop features of brains of complex organisms
Nov 20, 2023 (Nanowerk News) Cambridge scientists have shown that placing physical constraints on an artificially-intelligent system – in much the same way that the human brain has to develop and operate within physical and biological constraints – allows it to develop features of the brains of complex organisms in...
Webb reveals new features in heart of Milky Way
Nov 20, 2023 (Nanowerk News) The latest image from NASA’s James Webb Space Telescope shows a portion of the dense center of our galaxy in unprecedented detail, including never-before-seen features astronomers have yet to explain. The star-forming region, named Sagittarius C (Sgr C), is about 300 light-years from the Milky...
