New storage and information technology requires new higher performance materials. One of these materials is yttrium iron garnet, which has special magnetic properties. Thanks to a new process, it can now be transferred to any material. Developed by physicists at Martin Luther University Halle-Wittenberg (MLU), the method could advance the production of smaller, faster and more energy-efficient components for data storage and information processing. The physicists have published their results in the journal Applied Physics Letters.

Cornell University scientists have identified a new contender when it comes to quantum materials for computing and low-temperature electronics.

Using nitride-based materials, the researchers created a material structure that simultaneously exhibits superconductivity — in which electrical resistance vanishes completely — and the quantum Hall effect, which produces resistance with extreme precision when a magnetic field is applied.

“This is a beautiful marriage of the two things we know, at the microscale, that give electrons the most startling quantum proper...

As electronic devices saturate all corners of public and personal life, engineers are scrambling to find lightweight, mechanically stable, flexible, and easily manufactured materials that can shield humans from excessive electromagnetic radiation as well as prevent electronic devices from interfering with each other.

In a breakthrough report published in Advanced Materials—the top journal in the field— engineers at the University of California, Riverside describe a flexible film using a quasi-one-dimensional nanomaterial filler that combines excellent electromagnetic shielding with ease of manufacture.

“These novel films are promising for high-frequency communication technologies, which...

Over the past few years, computer scientists have created numerous computational techniques ...
