A research team of fusion scientists has succeeded in developing “the nano-scale sculpture technique” to fabricate an ultra-thin film by sharpening a tungsten sample with a focused ion beam. This enables the nano-scale observation of a cross-section very near the top surface of the tungsten sample using the transmission electron microscope. The sculpture technique developed

UK researchers have developed world-leading Compound Semiconductor (CS) technology that can drive future high-speed data communications. A team from Cardiff University’s Institute for Compound Semiconductors (ICS) worked with collaborators to innovate an ultrafast and highly sensitive ‘avalanche photodiode’ (APD) that creates less electronic ‘noise’ than its silicon rivals. APDs are highly sensitive semiconductor devices that

Tsukuba, Japan – A team at the University of Tsukuba introduced a new procedure of harvesting energy and organic molecules from algae using nanoporous graphene and porous graphene foams. By developing a reusable system that can evaporate water at high rate without the need for centrifugation or squeezing. This research has a great potential for

Scientists from Peter the Great St.Petersburg Polytechnic University (SPbPU) with their colleagues developed multifunctional metal alloys that emit and absorb heat at the same time and change their size and volume under the influence of a magnetic field. This effect is caused by changes in the structure of the substance. The alloys may be used

Theranostics is an emerging field of medicine whose name is a combination of “therapeutics” and “diagnostics”. The idea behind theranostics is to combine drugs and/or techniques to simultaneously – or sequentially – diagnose and treat medical conditions, and also monitor the response of the patient. This saves time and money, but can also bypass some

A window film with a specially designed molecule could be capable of taking the edge off the worst midday heat and instead distributing it evenly from morning to evening. The molecule has the unique ability to capture energy from the sun’s rays and release it later as heat. This is shown by researchers at Chalmers

IMAGE: The tubes consist of several walls that are perfectly uniform and just a few atoms thick. They display optical properties that make them perfect for use as fluorophores or photocatalysts. view more  Credit: EPFL If scientists could find a way to control the process for making semiconductor components on a nanometric scale, they could give
