Jan 19, 2022 (Nanowerk News) Metal-organic frameworks (MOFs) bring tremendous opportunities for separation of liquid chemicals using membranes. However, due to the lack of highly compact and robust micro-architecture to cope with complicated and tough separation situations, MOF membranes available for liquid chemical upgrading through pervaporation are rare. Recently, a...
Blue LEDs light the way toward sustainable development
Jan 18, 2022 (Nanowerk News) Light-emitting diodes (LEDs) are commonly used in the electronic displays in our TVs, smartphones, and other devices; now, researchers at the Institute of Chemical Reaction Design and Discovery (ICReDD) at Hokkaido University have utilized blue LEDs to develop a more sustainable way to make key...
Researchers uncover model for extremely luminous and fast rising supernova
Jan 18, 2022 (Nanowerk News) Appearing ten to a hundred times brighter at its peak, and with a much faster rise toward the peak, stellar explosions AT 2018cow (nicknamed the COW) and SN 2018gep (nicknamed the GEP) represent a new type of supernova called Fast Blue Optical Transient (FBOT), reports...
Mini electricity generator from quantum dots
Jan 18, 2022 (Nanowerk News) Machines and electronic devices often generate waste heat that is difficult to utilize. If electricity could be generated from this waste heat, it would offer a means for a clean and sustainable power production: Such a technology would be ideally suited for low-power electronics applications...
Controlling how ‘odd couple’ surfaces and liquids interact
Jan 18, 2022 (Nanowerk News) The wettability of a surface — whether drops of water or another liquid bead up or spread out when they come into contact with it — is a crucial factor in a wide variety of commercial and industrial applications, such as how efficiently boilers and...
SETI Institute teams up to help students design science program for sky-monitoring telescope based on the moon
Jan 18, 2022 (Nanowerk News) The SETI Institute teamed up with Louisiana State University (LSU) and Mississippi State University (MSU) to help students design the science program for AstronetX PBC's first lunar-based camera (L-CAM 1). The scientific program planning is funded by a Gordon and Betty Moore Foundation grant to...
James Webb Space Telescope mirrors aligned by 6-axis nanopositioning system
Jan 18, 2022 (Nanowerk News) Orbiting approximately one million miles from Earth, the James Webb Space Telescope (JWST) is the largest telescope ever launched into space – in its unfolded operational configuration it is nearly the size of a tennis court. Webb’s lightweight deployable primary mirror is segmented into 18...
Boxing up molecular machines
Jan 18, 2022 (Nanowerk News) Machines that are confined inside a cage or casing exhibit interesting properties by converting input energy into programmed functions. One such system is the mechanical gyroscope or gyrotop, a fascinating toy that amuses everyone with its incessant rotation. Gyroscopes also have practical applications in the...
Tiny nanogenerators generators could accelerate wound healing
Jan 18, 2022 (Nanowerk News) Tiny dressings that generate electricity in response to movement could accelerate wound healing and tissue regeneration. Scientists in Taiwan reviewed the latest advances and potential applications of wound healing technology in the journal Science and Technology of Advanced Materials ("Self-assisted wound healing using piezoelectric and...
New technique to convert greenhouse gasses into clean energy using photonics
Jan 18, 2022 (Nanowerk News) A European consortium is developing a new process that uses sunlight and LEDs to turn carbon dioxide and green hydrogen into clean energy products like methane gas and methanol liquid fuel. Called 'SPOTLIGHT', the consortium is creating a chemical process as well as a photonics...
