Mar. 27, 2023 A research group has discovered that near-infrared absorbing dyes, which had previously been considered to have closed-shell electronic structures, have an intermediate electronic structure, between ...
Jan. 25, 2023 Researchers have demonstrated for the first time a mechanically flexible silver mesh that is visibly transparent, allows high-quality infrared wireless optical communication and efficiently shields ...
July 13, 2023 A team of researchers has developed new LEDs which emit light simultaneously in two different wavelength ranges, for a simpler and more comprehensive way to monitor the freshness of fruit and ...
Mar. 30, 2023 An international team of researchers has found that a thin coating of MXene -- a type of two-dimensional nanomaterial -- could enhance a material's ability to trap or shed heat. The discovery, ...
June 15, 2023 A study demonstrates that graphene-based materials can be used to efficiently convert high-frequency signals into visible light, and that this mechanism is ultrafast and tunable. These outcomes open ...
Mar. 23, 2021 Scientists have discovered a potentially promising infrared LED and infrared detector component. This compound -- composed of calcium, silicon and oxygen -- is cheap to produce and non-toxic. Many of ...
Aug. 9, 2021 In photosynthesis and organic photovoltaics, pigment molecules convert light into electrical charge. Chemists have now produced an unusual organic pigment, which is 'switched on' by an ...
Nov. 9, 2021 An international research team has invented a 'smart' window material that controls heat transmission without blocking views, which could help cut the energy required to cool and heat ...
Aug. 25, 2022 A research team has developed a new reflective coating that can be used in counter-surveillance military applications to provide camouflage under the scrutiny of thermal imaging cameras. Their tests ...
June 28, 2023 With a flick of a switch, current technologies allow you to quickly change materials from being dark to light, or cold to hot, just by blocking or transmitting specific wavelengths. But now, inspired ...
