nanowires

A memristive element made from nanowires that functions in much the same way as a biological nerve cell has been produced by scientists from Forschungszentrum Jülich along with colleagues from Aachen and Turin. The component is able to save and process information, as well as receive numerous signals in parallel. The resistive switching cell made… Read more

Very small fibers made by a bacteria have the unique property of transporting charges at speeds of 1 billion electrons per second. The fibers are hair-like protein filaments called pili. Says Gemma Reguera, lead author and Michigan State University microbiologist: “This microbial nanowire is made of but a single peptide subunit. Being made of protein… Read more

Our need to store data is growing at an astonishing rate. An estimated 2.7 zettabytes (2.721) of data are currently held worldwide, equivalent to several trillion bytes for every one of the 7 billion people on Earth. Accessing this data quickly and reliably is essential for us to do useful things with it – the… Read more

Invention of the first integrated circularly polarized light detector on a silicon chip opens the door for development of small, portable sensors that could expand the use of polarized light for drug screening, surveillance, optical communications and quantum computing, among other potential applications. The new detector was developed by a team of Vanderbilt University engineers… Read more
