These bacteria could help to tackle the growing problem of plastic pollution and produce valuable chemicals and products...
Transparent wood-based coating doesn’t fog up
Sep 26, 2023 (Nanowerk News) Researchers have developed a way to turn a waste material from wood into a bio-based transparent film that can be used for anti-fogging or anti-reflective coatings on glasses or vehicle windows. In addition to offering an alternative to the toxic synthetic materials currently used, this...
Stacking order and strain boosts second-harmonic generation with 2D Janus hetero-bilayers
Sep 26, 2023 (Nanowerk News) A group of researchers from Tohoku University, Massachusetts Institute of Technology (MIT), Rice University, Hanoi University of Science and Technology, Zhejiang University, and Oak Ridge National Laboratory have proposed a new mechanism to enhance short-wavelength light (100-300 nm) by second harmonic generation (SHG) in a...
Transistor-inspired ultra-sensitive materials heat up advanced data security
Sep 26, 2023 (Nanowerk Spotlight) As data storage needs explode in the digital age, scientists are searching for new ways to securely encrypt information. Thermochromic fluorescent materials (TFMs) have gained significant attention in information storage and anti-counterfeiting. These materials change color and glow when heated, revealing hidden data. This unique...
Nanopore sequencing and DNA barcoding method gives hope of personalized medicine
Sep 25, 2023 (Nanowerk News) Currently, many diseases are diagnosed from blood tests that look for one biomarker (such as a protein or other small molecule) or, at most, a couple of biomarkers of the same type. The new method, developed by scientists at Imperial College London in a research...
Researchers challenge long-standing theory guiding nanoparticle treatment of tumors
Sep 26, 2023 (Nanowerk News) Researchers at the University of Toronto have developed a new theory to explain how nanoparticles enter and exit the tumours they are meant to treat, potentially rewriting an understanding of cancer nanomedicine that has guided research for nearly four decades. The Enhanced Permeability and Retention...
New spin-squeezing techniques let atoms work together for better quantum measurements
Sep 25, 2023 (Nanowerk News) Opening new possibilities for quantum sensors, atomic clocks and tests of fundamental physics, JILA researchers have developed new ways of “entangling” or interlinking the properties of large numbers of particles. In the process they have devised ways to measure large groups of atoms more accurately...
