Nov 19, 2021 (Nanowerk News) The properties of a complex and exotic state of a quantum material can be predicted using a machine learning method created by a RIKEN researcher and a collaborator (Physical Review X, "Dirac-type nodal spin liquid revealed by refined quantum many-body solver using neural-network wave function,...
Acquiring spectra from single excited molecules
Nov 19, 2021 (Nanowerk News) RIKEN physicists have taken a spectrum from a single molecule using a new nanospectroscopy technique they developed (Science, "Single-molecule laser nanospectroscopy with micro–electron volt energy resolution"). This ability to probe individual molecules will be invaluable for tailoring the properties of organic materials for use in...

Home > Press > Visualizing temperature transport: An unexpected technique for nanoscale characterization CREDIT Tokyo Tech Abstract:As devices continue to shrink, new challenges in their measurement and design present themselves. For devices based on molecular junctions, in which single molecules are bound to metals or semiconductors, we have a variety...
Advances in simple crystals for thermoelectric technology
Nov 19, 2021 (Nanowerk News) Space probes, gas pipelines, and other applications require an ongoing source of thermoelectric power without direct human maintenance, but current technologies for the corresponding energy conversion are inefficient. Now, researchers from Japan and Denmark have provided a greater understanding of the basis of ultralow thermal...
Using metal-organic frameworks to develop promising vaccine method against recurrent UTI
Nov 19, 2021 (Nanowerk News) Researchers at The University of Texas at Dallas are investigating the use of whole-cell vaccines to fight urinary tract infection (UTI), part of an effort to tackle the increasingly serious issue of antibiotic-resistant bacteria. Dr. Nicole De Nisco, assistant professor of biological sciences, and Dr....
By keeping ferroelectric ‘bubbles’ intact, researchers pave way for new devices
Nov 19, 2021 (Nanowerk News) When a magician suddenly pulls a tablecloth off a table laden with plates and glasses, there is a moment of suspense as the audience wonders if the stage will soon be littered with broken glass. Until now, an analogous dilemma had faced scientists working with...
Can defects turn inert materials into useful, active ones?
Nov 19, 2021 (Nanowerk News) Demonstrating that a material thought to be always chemically inert, hexagonal boron nitride (hBN), can be turned chemically active holds potential for a new class of catalysts with a wide range of applications, according to an international team of researchers. hBN is a layered material...
Single-atom dimer electrocatalyst for green hydrogen production
Nov 19, 2021 (Nanowerk News) The limited reservoir of fossils fuels and the ever-increasing threats of climate change have encouraged researchers to develop alternative technologies to produce eco-friendly fuels. Green hydrogen generated from the electrolysis of water using renewable electricity is considered a next-generation renewable energy source for the future....
Novel artificial genomic DNA can replicate and evolve outside the cell
Nov 19, 2021 (Nanowerk News) Professor Norikazu Ichihashi and his colleagues at the University of Tokyo have successfully induced gene expression from a DNA, characteristic of all life, and evolution through continuous replication extracellularly using cell-free materials alone, such as nucleic acids and proteins for the first time (ACS Synthetic...
