ORNL researchers have discovered a new type of quantum critical point, a new way in which materials change from one state of matter to another. Featured here are researchers Lekh Poudel (left), Andrew Christianson and Andrew May. Credit: ORNL/Genevieve...
Adding nanoscale particles of aluminum oxide increases the depth of the melting zone (MZ) in nickel and decreases the size of the heat-affected zone (HAZ). The bottom right image shows how even at higher temperatures the heat affected zone...

Researchers have found a way to trigger the innate, but previously hidden, ability of graphene to act as a superconductor - meaning that it can be made to carry an electrical current with zero resistance.
The...
An artist's rendition of Geobacter expressing electrically conductive nanowires. Microbiologists at UMass Amherst have discovered a new type of natural wire produced by bacteria that could greatly accelerate the development of sustainable "green" conducting materials for the electronics industry....
Dancing Weyl cones: When excited by tailored laser pulses (white spiral), the cones in a Dirac fermion material dance on a path (8-shape) that can be controlled by the laser light. This turns a Dirac material into a Weyl...
Argonne researchers are the first to capture the formation of nanomaterial defects in near-real time. Their work will help other researchers model the behavior of materials, a step that is key to engineering stronger, more reliable materials. (Image by...

Until recently, "flexible ferroelectrics" could have been thought of as the same type of oxymoronic...
Predictions of various deformation fields in the Vitreloy 1 simulation created at Rice University at various stages of deformation and with an ambient temperature of 698 degrees Fahrenheit. Each plot shows the equivalent stress overlaid with the strain field....

Just when lighting aficionados were in a dark place, LEDs came to the rescue. Over the past decade, LED technologies—short for light-emitting diode—have...

Gold is prized for its preciousness and as a conductor in electronics, but it is also important in scientific experimentation.
Ernest Rutherford utilised it when mapping the atom, in an experiment, which needed...
