A simple fractional-order capacitor has been developed by a team from KAUST. Made from a single component, this device expands the range of frequencies that can be achieved by these devices, making them better at energy storage. Traditional analogue components are resistors, capacitors, and inductors.
A porous material with tailor-made pockets stitched into its structure is a promising material for sensing noxious gases. A thin film of the material, coated onto an electrode, formed an electronic sensor that could detect traces of sulfur dioxide gas. The sensor is a significant step toward real-world devices that can sniff out dangerous gases in real air.
