Bioinspired supramolecular fibers drawn from a multiphase self-assembled hydrogel. Proceedings of the National Academy of Sciences, 2017; 201705380 DOI: 10.1073/pnas.1705380114

A team of architects and chemists from the University of Cambridge has designed super-stretchy and strong fibres which are almost entirely composed of water, and could be used to make textiles, sensors and other materials. The fibres, which resemble miniature bungee cords as they can absorb large amounts of energy, are sustainable, non-toxic and can be made at room temperature...

Moving things with a wave of the hand: thanks to Empa technology this dream could soon become real. A sensor made of electroconductive piezo-resistive fibers integrated in a wristband measures wrist movements and converts them into electrical signals, which can be read by a terminal device and interpreted. This can be used to steer drones or other electronic devices without a remote control. A wave to the left: the drone moves to the left. A wave to the right: the drone turns right. Clench your hand into a fist and it lands gently on the table.

Although motion sensors are nothing new, until now movements were primarily recorded using...

Outline of the microsatellite SOCRATES and the NICT optical ground station located in Koganei city. a. Picture of the lasercom terminal SOTA. b. Polarization states that encode the bits of the transmitted information. c. Optical ground station. d. Configuration diagram of the quantum receiver.

Big step toward building a truly-secure global communication network. The National Institute of Information and Communications Technology (NICT, President: Hideyuki Tokuda, Ph.D.) developed the world’s smallest and lightest quantum-communication transmitter (SOTA) onboard the microsatellite SOCRATES...

Drexel University researchers have developed two new electrode designs, using MXene material, that will allow batteries to charge much faster. The key is a microporous design that allows ions to quickly make their way to redox active sites. Credit: Drexel University

Researchers use mxene to push charging rate limits in energy storage. Can you imagine fully charging your cell phone in just a few seconds? Researchers in Drexel University’s College of Engineering can, and they took a big step toward making it a reality with their recent work unveiling of a new battery electrode design...
