An international team of physicists including Jennifer Cano, PhD, of Stony Brook University, has created a new material layered by two structures, forming a superlattice, that at a high temperature is a super-efficient insulator conducting current without dissipation and lost energy. The finding, detailed in a paper published in Nature Physics, could be the basis of research leading to new, better energy efficient electrical conductors.

The material is created and developed in a laboratory chamber. Over time atoms attach to it and the material appears to grow — similar to the way rock candy is formed...

New design overcomes long-standing LED efficiency problem – and can transform into a laser to boot. A new design for light-emitting diodes (LEDs) developed by a team including scientists at the National Institute of Standards and Technology (NIST) may hold the key to overcoming a long-standing limitation in the light sources’ efficiency...

Simple innovation expected to open multiple new avenues for quantum science. If we can harness it, quantum technology promises fantastic new possibilities. But first, scientists need to coax quantum systems to stay yoked for longer than a few millionths of a second.

A team of scientists at the University of Chicago’s Pritzker School of Molecular Engineering announced the discovery of a simple modification that allows quantum systems to stay operational – or “coherent” – 10,000 times longer than before...

North Carolina State University researchers have demonstrated a new technique for creating ultrasound images. The new approach is substantially simpler than existing techniques and could significantly drive down technology costs.

“Conventional ultrasound devices have a receiver that detects ultrasonic waves and converts them into an electrical signal, which is then sent to a computer that processes the signal and converts it into an image,” says Xiaoning Jiang, co-corresponding author of a paper on the work and a Duncan Distinguished Professor of Mechanical...
