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...
Safe chemotherapy nanocarrier methods for treating bacterial infections
Sep 25, 2023 (Nanowerk News) Many drugs and drug candidates have proven highly effective in killing bacteria or tumour cells. The problem is that they also harm the patient, and they are therefore used very sparingly or not at all. When used to treat for instance cancer, they are delivered...
New insights into the atmosphere and star of an exoplanet
Sep 25, 2023 (Nanowerk News) Astronomers have made important progress in understanding the intriguing TRAPPIST-1 exoplanetary system, which was first discovered in 2016 amid speculation it could someday provide a place for humans to live. Not only does the new research shed light on the nature of TRAPPIST-1 b, the...
Topological insulator catalysts for high-yield room-temperature synthesis of organoureas
Sep 25, 2023 (Nanowerk News) Synthetic fertilizers, one the most important developments in modern agriculture, have enabled many countries to secure a stable food supply. Among them, organic ureas (or organoureas) have become prominent sources of nitrogen for crops. Since these compounds do not dissolve immediately in water, but instead...
Copper-based 2D catalysts efficiently turn carbon dioxide into methane
Sep 25, 2023 (Nanowerk News) Technologies for removing carbon from the atmosphere keep improving, but solutions for what to do with the carbon once it’s captured are harder to come by. The lab of Rice University materials scientist Pulickel Ajayan and collaborators developed a way to wrest the carbon from...
Hidden supermassive black holes reveal their secrets through radio signals
Sep 25, 2023 (Nanowerk News) Astronomers have found a striking link between the amount of dust surrounding a supermassive black hole and the strength of the radio emission produced in extremely bright galaxies. The findings are published in the Monthly Notices of the Royal Astronomical Society ("A striking relationship between...
