Quantum effect triggers unusual material expansion

You know how you leave space in a water bottle before you pop it in the freezer—to accommodate the fact that water expands as it freezes? Most metal parts in airplanes face the more common opposite problem. At high altitudes ...

Pressure transforms a semiconductor into a new state of matter

(Phys.org) —By applying pressure to a semiconductor, researchers have been able to transform a semiconductor into a "topological insulator" (TI), an intriguing state of matter in which a material's interior is insulating ...

Field-effect transistors get a boost from ferroelectric films

(Phys.org) —As microelectronics get smaller and smaller, one of the biggest challenges to packing a smartphone or tablet with maximum processing power and memory is the amount of heat generated by the tiny "switches" at ...

Probing hydrogen under extreme conditions

(Phys.org) -- How hydrogen--the most abundant element in the cosmos--responds to extremes of pressure and temperature is one of the major challenges in modern physical science. Moreover, knowledge gleaned from experiments ...

Squashing Silane into Metal

(PhysOrg.com) -- Squeeze it hard enough and hydrogen, the most abundant and lightest element in our Universe, strangely takes on a metallic nature. During this state, as it loses hold of its electrons, hydrogen is believed ...

Scientists streamline process for controlling spin dynamics

Marking a major achievement in the field of spintronics, researchers at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory and Yale University have demonstrated the ability to control spin dynamics in magnetic ...

Quantum X-ray microscope in development

Scientists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory have begun building a quantum-enhanced X-ray microscope at the National Synchrotron Light Source II (NSLS-II). This groundbreaking microscope, ...

Cell membrane proteins imaged in 3-D

A team of scientists including researchers at the National Synchrotron Light Source II (NSLS-II)—a U.S. Department of Energy (DOE) Office of Science User Facility at DOE's Brookhaven National Laboratory—have demonstrated ...
