Fuentes/UB An international team led by researchers of the University of Barcelona builds the smallest and cheapest high-resolution microscope to date. To build it, researchers developed new nanoLEDs that act as a lightning source and determine the resolution of the microscope without lenses. The team created a new

To see how molecules bond, break, or change their structure,

Wearable pressure sensors are designed to respond to very small changes in bodily

Nanoengineers at the University of California San Diego have developed a “wearable microgrid” that harvests and stores energy from the human body to power small electronics. It consists of three main parts: sweat-powered biofuel cells, motion-powered devices called triboelectric generators, and energy-storing supercapacitors. All parts are flexible, washable and can be screen printed onto clothing.

In a new paper published in Light: Science & Applications, the group led by Professor Andrea Fratalocchi from Primalight Laboratory of the Computer, Electrical and Mathematical Sciences and Engineering (CEMSE) Division, King Abdullah University of Science and Technology (KAUST), Saudi Arabia, introduced a new patented, scalable flat-optics technology manufactured with inexpensive semiconductors. The KAUST-designed technology

In recent years there has been an increased focus on the circular economy and a heightened demand for products made of recyclable materials, however many materials can only be recycled so many times before they begin to wear out. This is the case with carbon fibre reinforced polymer (CFRP) composites, non-biodegradable materials which, until now,
