Sep 14, 2022 (Nanowerk News) Various chemical reactions occur one after another in cells, and life is maintained as each step of the reaction is regulated without error. Recently, a Korean research team has developed a dual-catalyst system that can precisely control catalytic reactions like cells. A POSTECH research team...
Fuel from a greenhouse gas made with single gold atoms
Sep 14, 2022 (Nanowerk News) The photocatalytic conversion of CO2 occurs through a series of processes in which electrons are transferred. This can result in various products, including carbon monoxide (CO), methanol (CH3OH), methane (CH4), and other hydrocarbons. Eight electrons must be transferred on the way from CO2 to CH4—...
new evidence of baby planet in the making
Sep 14, 2022 (Nanowerk News) Astronomers agree that planets are born in protoplanetary disks — rings of dust and gas that surround young, newborn stars. While hundreds of these disks have been spotted throughout the universe, observations of actual planetary birth and formation have proved difficult within these environments. Now,...
Making and breaking of chemical bonds in single nanoconfined molecules
Sep 14, 2022 (Nanowerk News) Researchers around the world are working to develop efficient materials to convert CO2 into usable chemical substances – work that is particularly pressing in view of global warming. A team from the University of Göttingen, Germany, and the Ulsan National Institute for Science, South Korea,...
Reusing 1 kg of clothing saves 25 kg of CO2
Sep 14, 2022 (Nanowerk News) The UPC’s INTEXTER has conducted a pioneering analysis to calculate the share of fibres used in the clothes that are dumped in textile collection bins. The study uses an innovative methodology and is therefore more accurate than other approaches so far. It is part of...
Interplay of electronics and photonics as a new basis for quantum computers
Sep 14, 2022 (Nanowerk News) For building quantum computers, making use of both electronics and photonics – technology that works with light – on one and the same chip, is promising. Thanks to silicon technology that we know well from today’s electronic devices, quantum devices could be better protected from...
Nanorattles shake up new possibilities for disease detection
Sep 13, 2022 (Nanowerk News) Researchers at Duke University have developed a unique type of nanoparticle called a “nanorattle” that greatly enhances light emitted from within its outer shell. Loaded with light scattering dyes called Raman reporters commonly used to detect biomarkers of disease in organic samples, the approach can...
New method for comparing neural networks exposes how artificial intelligence works
Sep 13, 2022 (Nanowerk News) A team at Los Alamos National Laboratory has developed a novel approach for comparing neural networks that looks within the “black box” of artificial intelligence to help researchers understand neural network behavior. Neural networks recognize patterns in datasets; they are used everywhere in society, in...
