A team of researchers from the Nanyang Technological University (NTU) in Singapore has developed a thermal invisibility cloak that would improve heat distribution in electronic devices by redirecting incoming heat. The cloaks are capable of guiding heat around a hidden object, thus resulting in complete thermal invisibility. “Based on carefully engineered metamaterials – … [Read more...]
LED Displays Added to Clothing; New Opportunities for Wearables
A team of researchers from Holst Centre at Ghent University have produced the world’s first stretchable thin-film transistor driven by LED display which is laminated into textiles. This new discovery paves the way for LED displays in wearable clothing. “Wearable devices such as healthcare monitors and activity trackers are now a part of everyday life for many people. Today's … [Read more...]
New Magnetocaloric Material Could Lead to Greener Refrigerators
The recent discovery of a new magnetocaloric material with intriguing characteristics could lead to a greener method of cooling, potentially providing a more environmentally-friendly alternative to standard refrigeration. A joint team of researchers from Canada and Bulgaria have developed a new method of green cooling by identifying a multiferroic compound, HoMn2O5, that could … [Read more...]
Rugged Circuit Functions at Temperatures Greater than 350 Degrees Celsius
Researchers at the University of Arkansas have developed integrated circuits capable of surviving at temperatures greater than 350 degrees Celsius, or approximately 660 degrees Fahrenheit. Created using silicon carbide, a semiconducting material that is more rugged than conventional materials used in electronics, the new circuits are expected to improve the operation of analog … [Read more...]
Controlling Thermal Conductivity to Improve Energy Storage
Researchers at the University of Illinois at Urbana-Champaign have experimentally shown for the first time that the thermal conductivity of lithium cobalt oxide (LixCoO2), a material used in the cathodes of lithium-ion batteries, can be reversibly electrochemically modulated over a significant range. Many technologies require control over the flow of heat through materials in … [Read more...]
