Technology developments for 'nanogap electrodes' to purify various ultra-fine floating particles in the air and water. Scalable massive methodology control makes application in the environmental and medical sciences possible.
Cell phone batteries often heat up and, at times, can burst into flames. In most cases, the culprit behind such incidents can be traced back to lithium batteries. Despite providing long-lasting electric currents that can keep devices powered up, lithium batteries can internally short circuit, heating up the device.
Researchers have invented a technology that can prevent lithium batteries from heating and failing.
Engineers discover the possibility of using pencils to draw bioelectronics on human skin.
A novel mechanism for electron optics in two-dimensional solid-state systems opens up a route to engineering quantum-optical phenomena in a variety of materials.
A customizable smart window harnesses and manipulates solar power to save energy and cut costs.
MOFs and COFs are porous materials with a broad range of applications, such as gas storage, CO2 capture or drug delivery. Researchers have demonstrated that spray-drying is a suitable method for producing this kind of materials.
Using techniques similar to those they employed to develop laser-induced graphene, scientists turned adhesive tape into a silicon oxide film that replaces troublesome anodes in lithium metal batteries.
Small amounts of plutonium (Pu) were released from the damaged Fukushima Daiichi Nuclear Power Plant (FDNPP) reactors into the environment during the site's 2011 nuclear disaster. However, the physical, chemical, and isotopic form of the released Pu has remained unknown. Now, recent work has shown that Pu was included inside cesium-rich microparticles (CsMPs) that were emitted from the site.
For the very first time, scientists have successfully imitated the functioning of brain neurons using semiconductor materials.
This phenomenon has a number of applications in magnetic sensors and magnetic reading heads, which, however, have not been reported in van der Waals heterostructures before.
Scientists have confirmed a long-standing theoretical prediction for high-temperature superconductors. Different states of matter make superconductivity possible. One of those theorized states of matter is called a pair density wave. The scientists confirmed pair density waves using advanced microscopic imaging techniques.
Vibrations of atoms in a crystal of the semiconductor gallium arsenide are impulsively shifted to a higher frequency by an optically excited electric current. The related change in the spatial distribution of charge between gallium and arsenic atoms acts back on their motions via electric interactions.
Researchers have discovered the highly selective separation of CO2 over nitrogen in composite membranes with ultrathin layers with selectivity governed by the molecularly thin interface formed between polymers.
Researchers have developed a novel noninvasive approach called nano-radiomics that analyzes imaging data to assess changes in the tumor microenvironment that are not detected with conventional imaging methods.
Researchers use sunlight and a laser-etched metal surface to evaporate and purify water for safe drinking at greater than 100 percent efficiency. The method could help relieve water shortages in drought-stricken areas and be helpful in water desalinization projects.
Researchers have improved on the technique of local processing of composites based on nanoporous glass with addition of silver and copper; now, it is possible to predict with high accuracy the optical properties of a plasmonic component.
