The device, developed by HWY Technologies, is based on a design concept known as microwave-assisted magnetic recording, or MAMR. This tech...

Credit: TU Wien For decades, there has been a trend in microelectronics towards ever smaller and more compact transistors. 2D materials such as graphene are seen as a beacon of hope here: they are the thinnest material layers that can possibly exist, consisting of only one or a few atomic layers. Nevertheless, they can conduct electrical currents - conventional silicon technology, on the other hand, no longer works properly if the layers become too thin. However, such materials are not used in a vacuum; they have to be combined with suitable insulators - in order to seal them off from unwante...

Credit: University of Warwick Flash sintering is a ceramic processing technique which uses electric current to intensively heat the ceramic sample internally rather than using only external furnace heating. The process can lower ceramic processing temperatures and durations significantly, enabling ceramics to be co-processed with metals or other materials, and reducing energy use. However, the process can result in low quality ceramics due to weaknesses caused by inhomogeneities in the microstructure. The origins of these inhomogeneities caused by thermal gradients in the material during flas...
