The material, gallium arsenide, is used to observe states in which electrons no longer obey the laws of single-particle physics, but instead are governed by…
However, researchers at the California Institute of Technology (Caltech) have now created the first tunable acoustic diode-a device that allows acoustic…
These circular chambers were designed to amplify and direct sound waves so that, when standing in the right spot, a whisper could be heard from across the…
“We can make a material now that’s truly multifunctional by simply circulating fluids that do different things within the same material system,” said Scott…
Extremely hard, diamond-like carbon coatings are used to protect hard disks in computers and ensure that sliding bearings remain smooth. In the future they…
“We’ve discovered a way to change the three-dimensional structure of a well-established semiconductor material to enable new optical properties while…
“The ongoing assumption was that if you have a mixture of different sized particles in a liquid, the faster-settling particles will end up on the bottom,” said…
However, to date there is no standard method for measuring the absolute output power of terahertz lasers, one source of this type of radiation. Now,…
Researchers at Rensselaer Polytechnic Institute have developed a new method to harvest energy from flowing water. This discovery aims to hasten the creation of…
The technique, which uses a heated atomic force microscope (AFM) tip to produce patterns, could facilitate high-density, low-cost production of complex…
Rice University scientists have achieved a pivotal breakthrough in the development of a cable that will make an efficient electric grid of the future possible.Armchair quantum wire (AQW) will be a weave of metallic nanotubes that can carry electricity with negligible loss over long distances. It will be an ideal replacement for the nation's copper-based grid, which leaks electricity at an estimated 5 percent per 100 miles of transmission, said Rice chemist Andrew R. Barron, author of a paper about the latest step forward published online by the American Chemical Society journal Nano Letters. …
Sepiolite is a lightweight porous mineral used in cat litter and other applications. The extraordinary properties of this clay make it a highly sought after…
A University of Connecticut scientist has perfected a method for creating quick-changing, variable colors in films and displays, such as sunglasses, that could…
The latest product from the Vespel® SCP family is intended to help customers looking for extended part life in many sealing and bearing applications,…
That's because the collaborators have demonstrated that the more widely and uniformly dispersed nanoscale plates of clay are in a polymer, the more fire…
Their new paper** demonstrates how both wrinkles in the graphene sheet and/or chance contaminants from processing—possibly hiding in those folds—disrupt and…
