X-rays help scientists uncover new forms of material using designer DNA
Mar 31, 2022 (Nanowerk News) The new method of synthesizing crystals leads researchers to a brand new phase of metal, which may be useful for new technologies. Results were confirmed using the Advanced Photon Source. A research team led by Northwestern University and the University of Michigan has developed a...
The Human Genome Project pieced together only 92% of the DNA
Mar 31, 2022 (Nanowerk News) When the Human Genome Project announced that they had completed the first human genome in 2003, it was a momentous accomplishment - for the first time, the DNA blueprint of human life was unlocked. But it came with a catch - they weren’t actually able...
Graphene gets enhanced by flashing
Mar 31, 2022 (Nanowerk News) Flashing graphene into existence from waste was merely a good start. Now Rice University researchers are customizing it. The Rice lab of chemist James Tour has modified its flash Joule heating process to produce doped graphene that tailors the atom-thick material’s structures and electronic states...
Persistent swinging of electrons between atomic sites in crystals
Mar 31, 2022 (Nanowerk News) Phonons are quantum excitations which correspond to vibrations of the regular atomic array of a crystal. This crystal lattice consists of a large number of unit cells with an identical atomic arrangement. In the elementary adiabatic picture, the motions of electrons in the crystal follow...
Physiological signals could be the key to ’emotionally intelligent’ AI
Mar 31, 2022 (Nanowerk News) Speech and language recognition technology is a rapidly developing field, which has led to the emergence of novel speech dialog systems, such as Amazon Alexa and Siri. A significant milestone in the development of dialog artificial intelligence (AI) systems is the addition of emotional intelligence....
New method measures nanoscale material response at high magnification
Mar 31, 2022 (Nanowerk News) The safety glass used in the windshields of limousines and military vehicles needs to be hard, strong and shatter-proof, but also thin—both for visibility and to reduce its weight, a particularly important feature for aerospace vehicles. The use of a promising new transparent ceramic spinel...
New study solves mystery of how soft liquid droplets erode hard surfaces
Mar 31, 2022 (Nanowerk News) A first-of-its-kind study led by University of Minnesota Twin Cities researchers reveals why liquid droplets have the ability to erode hard surfaces. The discovery could help engineers design better, more erosion-resistant materials. Using a newly developed technique, the researchers were able to measure hidden quantities...
Conductive supercrystals for next-generation electronic technology
Mar 30, 2022 (Nanowerk News) A new study of an international team of chemists introduces a breakthrough in making nanocrystals function together electronically. Published in the journal Science ("Self-assembly of nanocrystals into strongly electronically coupled all-inorganic supercrystals"), the research may open the doors to future devices, such as next-generation displays...
Researchers find topological phenomena at high, technologically relevant frequencies
Mar 30, 2022 (Nanowerk News) New research published in Nature Electronics ("Gigahertz topological valley Hall effect in nanoelectromechanical phononic crystals") describes topological control capabilities in an integrated acoustic-electronic system at technologically relevant frequencies. This work paves the way for additional research on topological properties in devices that use high-frequency sound...
