Scientists in Australia used tin mono-sulfide nanosheets to create the thinnest X-ray detector ever made. The detector is less than 10 nanometers thick. Previously, the thinnest X-ray detectors created were between 20–50 nanometers.
Aerospace engineers at the University of Illinois Urbana-Champaign used machine learning to predict stress in copper at the atomic scale. Eventually, the algorithm was able to predict very accurately the grain boundary stresses from both simulation and experimental image data with atomic-level resolution.
Rice University researchers suggest growing borophene on hexagonal boron nitride rather than the more traditional metallic surfaces typically used in molecular beam epitaxy. The weaker van der Waals forces between the growing borophene and relatively chemically inert hBN would make it easier to remove the material from the substrate.
An international research team led by Kiel University succeeded in repeatedly heating and cooling aerograph and the air contained inside to very high temperatures in an extremely short period of time. This process opens the door to extremely powerful pumps, compressed air applications, or sterilizing air filters in miniature.
Researchers in Australia and China found a cheaper, easier way to organize large groups of carbon nanotubes without lithography. They used a dewetting process to organize nickel catalyst particles in a particular way.
U.S. manufacturer UbiQD developed a solar window with laminated glass and luminescent solar concentrators, based on copper indium sulfide and zinc sulfide quantum dots. It is now testing pilot installations at a Holiday Inn Express hotel in Los Alamos, New Mexico.
A research team co-led by scholars from City University of Hong Kong and Germany discovered the quantum confinement effect in a photocatalyst of a 3D-ordered macroporous structure. The quantum confinement effect was found to enable hydrogen production under visible light.
Scientists at Oak Ridge National Laboratory developed a scalable, low-cost method to improve the joining of materials in solid-state batteries. The electrochemical pulse the ORNL researchers used eliminates the voids that form when joining layers of lithium metal anode material with a solid electrolyte material.
By using a combination of physics-based modeling and advanced simulations, Texas A&M University researchers found the key underlying factors that cause radiation damage to nuclear reactors.
A new Cornell University-led study identifies several keys to sustainably managing the influx of electric vehicle batteries, with an emphasis on battery chemistry, second-life applications, and recycling.
Researchers built a hydrogel battery that could offer a biocompatible power source for medical implants. The battery’s electrodes are made from a polyacrylamide-carbon nanotube gel infused with lithium manganese oxide (cathode) and lithium titanium phosphate (anode). The electrolyte is a polyacrylamide-lithium chloride hydrogel.
Chemists at Johannes Gutenberg University Mainz developed a method that could drastically reduce CO2 emissions from cement production in the long run. In this process, the raw lime is no longer converted into burnt lime in coal-fired kilns but is simply milled with solid sodium silicate.
Korean researchers successfully extracted high-quality magnesium sulphate, devoid of the commonly found calcium impurities, through a novel ethanol-based method from readily available seawater desalination brine.
A new paper by Staffordshire University and Rozalia Project shows that a significant amount of microplastics and microfibers from scientists’ clothing and gear mixes with environmental pollution in the water samples.
High-performance ceramics provide key components—but only if they are defect-free. To detect rejects at an early stage, researchers at Fraunhofer IKTS developed an in-line inspection method based on laser speckle photometry.
Oak Ridge National Laboratory researchers designed a polymer to bind and strengthen silica sand for binder jet additive manufacturing. The printable polymer enables sand structures with intricate geometries and exceptional strength—and is also water soluble.
An international research team led by Nanyang Technological University, Singapore invented a “smart” window material that controls heat transmission without blocking views. The new material has a specifically designed nanostructure and comprises advanced materials like titanium dioxide, tungsten trioxide, neodymium-Niobium, and tin oxide.
Researchers from the University of Surrey’s Advanced Technology Institute and the University of São Paulo developed a new analysis technique that enables researchers to investigate the complex interconnected behavior of supercapacitor electrodes made from layers of different materials.
Researchers at the Australian National University in Canberra studied keshi pearls collected from Akoya pearl oysters and found that fluctuations in the thicknesses of the pearls’ layers of nacre is dependent on the thickness of previous layers.
Researchers stabilized a perovskite’s luminescent crystal form, which usually decomposes rapidly at temperatures below 320°C, by freezing it in a metal–organic framework glass.
Researchers at the Korea Institute of Civil Engineering and Building Technology developed a world-first forensic tool for evaluating fire-damaged concrete structures. It produces valuable outputs by only taking samples of 1~2 grams at every 10-mm depth of fire-damaged concrete.
