Aug 15, 2023 (Nanowerk News) Two molecular languages at the origin of life have been successfully recreated and mathematically validated, thanks to pioneering work by Canadian scientists at Université de Montréal. Published this week in the Journal of American Chemical Society ("Programming chemical communication: allostery vs multivalent mechanism"), the breakthrough...
Carbon-based quantum technology
Aug 15, 2023 (Nanowerk News) Graphene nanoribbons have outstanding properties that can be precisely controlled. Researchers from Empa and ETH Zurich, in collaboration with partners from Peking University, the University of Warwick and the Max Planck Institute for Polymer Research, have succeeded in attaching electrodes to individual atomically precise nanoribbons,...
Programmable DNA hydrogels for advanced cell culture and personalized medicine
Aug 15, 2023 (Nanowerk News) In vitro culture of biological cells plays an important role in advancing biological research. However, currently available cell culture materials have significant drawbacks. Many of them are derived from animal sources, leading to poor reproducibility, and making it difficult to fine-tune their mechanical properties. Therefore,...
from tunable conductance to reconfigurable photoresponse
Aug 15, 2023 (Nanowerk News) In traditional vision systems, the optical information is captured by a frame-based digital camera, and then the digital signal is processed afterwards using machine-learning algorithms. In this scenario, a large amount of data (mostly redundant) has to be transferred from a standalone sensing elements to...
Using magnetic effects in electrons for a hundredfold reduction in the power consumption of future chips
Aug 15, 2023 (Nanowerk News) Electronic devices are shrinking all the time. At the same time, the computer chips inside them are getting more and more powerful, but they are also using more energy, and running hotter. This makes it essential to find new ways to reduce the power consumption...
Astronomers confirm Maisie’s galaxy is among earliest ever observed
Aug 15, 2023 (Nanowerk News) Thanks to the James Webb Space Telescope, astronomers racing to find some of the earliest galaxies ever glimpsed have now confirmed that a galaxy first detected last summer is in fact among the earliest ever found. The findings are in the journal Nature ("Confirmation and...
Nanomaterial offers new way to control fire
Aug 14, 2023 (Nanowerk News) High-temperature flames are used to create a wide variety of materials – but once you start a fire, it can be difficult to control how the flame interacts with the material you are trying to process. Researchers have now developed a technique that utilizes a...
Gold buckyballs, oft-used nanoparticle ‘seeds’ are one and the same
Aug 14, 2023 (Nanowerk News) Rice University chemists have discovered that tiny gold “seed” particles, a key ingredient in one of the most common nanoparticle recipes, are one and the same as gold buckyballs, 32-atom spherical molecules that are cousins of the carbon buckyballs discovered at Rice in 1985. Carbon...
Flexible perovskite solar cells achieve record indoor efficiency on PET films
Aug 14, 2023 (Nanowerk News) Perovskite photovoltaic devices have garnered much attention from both the academic and industrial R&D world because they combine high power conversion efficiencies and low-cost manufacturing processes since they can be deposited in ink form or through simple evaporation. Concurrently, the rapid expansion of the Internet...
Scientists discover novel way of reading data in antiferromagnets, unlocking their use as computer memory
Aug 14, 2023 (Nanowerk News) Scientists led by Nanyang Technological University, Singapore (NTU Singapore) investigators have made a significant advance in developing alternative materials for the high-speed memory chips that let computers access information quickly and that bypass the limitations of existing materials. They have discovered a way that allows...
