 E-Mail An innovative analysis of two-dimensional (2D) materials from engineers at the University of Surrey could boost the development of next-generation solar cells and LEDs. Three-dimensional perovskites have proved themselves remarkably successful materials for LED devices and solar panels in the past decade. One key issue with these materials, however, is their stability, with device performance decreasing quicker than other state-of-the-art materials. The engineering community believes t...

 E-Mail IMAGE: In this schematic, the teal balls represent boron and the red balls are hydrogen. view more  Credit: Northwestern University Northwestern University researchers have, for the first time, created borophane -- atomically thin boron that is stable at standard temperatures and air pressures. Researchers have long been excited by the promise of borophene -- a single-atom-thick sheet of boron -- because of its strength, flexibility and electronics properties. Stronger, lighte...

 E-Mail IMAGE: The algorithm will be implemented on brain-inspired computing systems, like the spike-based SpiNNaker (pictured here). SpiNNaker is part of the Human Brain Projects EBRAINS research infrastructure. view more  Credit: © Forschungszentrum Jülich Most new achievements in artificial intelligence (AI) require very large neural networks. They consist of hundreds of millions of neurons arranged in several hundred layers, i.e. they have very "deep" network structures. These l...

 E-Mail IMAGE: A new $7.5 million Department of Defense grant is seeking to build a super camera that combines multiple metasurfaces that together can extract almost every bit of information that light... view more  Credit: Mark Brongersma, Stanford DURHAM, N.C. - Engineers at Duke University are leading a nationwide effort to develop a camera that takes pictures worth not just a thousand words, but an entire encyclopedia. Funded by a five-year, $7.5 million grant through the Departm...

 E-Mail IMAGE: The cellulose yarn, which the researchers present in the article, is practical to work with and could be used to make clothing with smart functions. Using a standard household sewing... view more  Credit: Anna-Lena Lundqvist/Chalmers University of Technology Electronic textiles offer revolutionary new opportunities in various fields, in particular healthcare. But to be sustainable, they need to be made of renewable materials. A research team led by Chalmers University o...

 E-Mail IMAGE: Schematic diagram of the process of material phase transition, ex-solution particle formation, and the change in catalytic activity depending on the reduction environment. view more  Credit: POSTECH Fuel cells, which are attracting attention as an eco-friendly energy source, obtain electricity and heat simultaneously through the reverse reaction of water electrolysis. Therefore, the catalyst that enhances the reaction efficiency is directly connected to the performance ...

Credit: Jilin University Scientists have developed a see-through glass display with a high white light contrast ratio that smoothly transitions between a broad spectrum of colors when electrically charged. The technology, from researchers at Jilin University in Changchun, China, overcomes limitations of existing electrochromic devices by harnessing interactions between metal ions and ligands, opening the door for numerous future applications. The work appears March 10 in the journal Chem. "We ...

An international research team led by NUST MISIS has developed a new iron-cobalt-nickel nanocomposite with tunable magnetic properties. The nanocomposite could be used to protect money and securities from counterfeiting. The study was published in Nanomaterials.
