Dec 16, 2021 (Nanowerk News) Scientists have developed an all-season smart-roof coating that keeps homes warm during the winter and cool during the summer – without consuming natural gas or electricity. Research findings reported in the journal Science ("Temperature-adaptive radiative coating for all-season household thermal regulation") point to a groundbreaking...
Breakthrough in using CRISPR-Cas9 to target fat cells
Dec 16, 2021 (Nanowerk News) Fat—it is vital for life but too much can lead to a host of health problems. Studying how fat, or adipose, tissue functions in the body is critical for understanding obesity and other issues, yet structural differences in fat cells and their distribution throughout the...
Negative capacitance in topological transistors could reduce computing’s unsustainable energy load
Dec 16, 2021 (Nanowerk News) Australian researchers have discovered that negative capacitance could lower the energy used in electronics and computing, which represents 8% of global electricity demand. The researchers at four universities within the ARC Centre of Excellence in Future Low-Energy Electronics Technologies (FLEET) applied negative capacitance to make...
Scientists predict the rotation periods of stars
Dec 16, 2021 (Nanowerk News) The Leibniz Institute for Astrophysics Potsdam (AIP) announces the completion of a major three-publication survey of one of the richest accessible open star clusters. The final study features a method of deriving the rotation periods of stars from just one observation of the stellar activity...
Researchers developed simple method to upcycle okara using 3D printing
Dec 16, 2021 (Nanowerk News) Researchers from the Singapore University of Technology and Design (SUTD) developed a method to perform direct ink writing (DIW) 3D printing of okara—a soybean byproduct generated from the production of soy milk and bean curd—without using food thickeners (ACS Food Science and Technology, "3D Printing...
Whispering electrons in graphene
Dec 16, 2021 (Nanowerk News) Whispering gallery modes (WGMs) are quite common in acoustics and optics. They denote the guided waves circulating along a concave surface, the seminal example being the whispering galleries of St. Paul’s cathedral: someone whispering on one side of the gallery can be heard all along...
Demonstrating Feshbach resonances between a single ion and ultracold atoms
Dec 16, 2021 (Nanowerk News) A team led by Prof. Dr. Tobias Schätz, Professor of Atomic and Quantum Physics at the Institute of Physics at the University of Freiburg, Dr. Pascal Weckesser, Fabian Thielemann and colleagues, demonstrate magnetic Feshbach resonances between a single barium ion and lithium atoms at near...
Magnetic tunnel junction technology for the Angstrom semiconductor era
Dec 15, 2021 (Nanowerk News) A research group at Tohoku University has shown that fast switching down to 3.5 ns in sub-five-nm ultra-small magnetic tunnel junctions (MTJs) can be achieved by engineering relaxation time, which governs fast magnetization dynamics (IEEE International Electron Devices Meeting, "Fast Switching Down to 3.5 ns...
Understanding phase change materials for thermal energy storage
Dec 15, 2021 (Nanowerk News) As the world searches for practical ways to decarbonize our activities and mitigate associated climate change, approaches to alternative energy are hampered by the intermittent nature of energy sources, such as solar and wind. One possible solution to help boost reliability and adoption of such...
