Chemists at UCL have discovered a new property of flames, which allows them to control reactions at a solid surface in a flame and opens up a whole new field of chemical innovation.
View ArticleHigh glucose levels could impair ferroelectricity in body's connective tissues
High sugar levels in the body come at a cost to health. New research suggests that more sugar in the body could damage the elastic proteins that help us breathe and pump blood. The findings could have...
View ArticleMagnetic mirrors enable new technologies by reflecting light in uncanny ways
As in Alice's journey through the looking-glass to Wonderland, mirrors in the real world can sometimes behave in surprising and unexpected ways, including a new class of mirror that works like no other.
View Article'Reverse engineering' materials for more efficient heating and cooling
If you've ever gone for a spin in a luxury car and felt your back being warmed or cooled by a seat-based climate control system, then you've likely experienced the benefits of a class of materials...
View ArticleNew research lights the way to super-fast computers
New research published today in the journal Nature Communications, has demonstrated how glass can be manipulated to create a material that will allow computers to transfer information using light. This...
View ArticleEngineers develop graphene-based biosensor that works in three ways at once
(Phys.org)—One of nanotechnology's greatest promises is interacting with the biological world the way our own cells do, but current biosensors must be tailor-made to detect the presence of one type of...
View ArticleSilver nanowires demonstrate unexpected self-healing mechanism
With its high electrical conductivity and optical transparency, indium tin oxide is one of the most widely used materials for touchscreens, plasma displays, and flexible electronics. But its rapidly...
View ArticleSemiconductor works better when hitched to graphene
Graphene – a one-atom-thick sheet of carbon with highly desirable electrical properties, flexibility and strength – shows great promise for future electronics, advanced solar cells, protective coatings...
View ArticleFirst scientific publication from data collected at NSLS-II
Just weeks after the National Synchrotron Light Source II (NSLS-II), a U.S. Department of Energy Office of Science User Facility at Brookhaven National Laboratory, achieved first light, a team of...
View ArticleSqueezable nano electromechanical switches with quantum tunneling function
A longstanding problem in designing nanoscale electromechanical switches is the tendency for metal-to-metal contacts to stick together, locking the switch in an "on" position. MIT electrical...
View ArticleNovel plastic could spur new green energy applications, 'artificial muscles'
A plastic used in filters and tubing has an unusual trait: It can produce electricity when pulled or pressed. This ability has been used in small ways, but now researchers are coaxing fibers of the...
View ArticleEngineers create structures tougher than bulletproof vests
Researchers at UT Dallas have created new structures that exploit the electromechanical properties of specific nanofibers to stretch to up to seven times their length, while remaining tougher than Kevlar.
View ArticleSingle-walled carbon nanotube composites show great promise for use in...
As we approach the miniaturization limits of conventional electronics, alternatives to silicon-based transistors—the building blocks of the multitude of electronic devices we've come to rely on—are...
View ArticleNew studies explain insulator-to-metal transition of vanadium dioxide
When heated to just above room temperature, the electrical conductivity of vanadium dioxide (VO2) abruptly increases by a factor of 10,000. Experiments coupled with high-performance computation reveal...
View ArticleNanotubes with two walls have singular qualities
Rice University researchers have determined that two walls are better than one when turning carbon nanotubes into materials like strong, conductive fibers or transistors.
View ArticleMethod for creating high-quality two-dimensional materials could enable...
Two-dimensional materials have a whole host of exotic properties because they are just one atom thick. A*STAR researchers have now developed a method for creating large areas of atom-thin material for...
View ArticleHeat makes electrons spin in magnetic superconductors
Physicists have shown how heat can be exploited for controlling magnetic properties of matter. The finding helps in the development of more efficient mass memories. The result was published yesterday...
