New insights on 'captured' electrons could improve flash memory

An entirely new model of the way electrons are briefly trapped and released in tiny electronic devices suggests that a long-accepted, industry-wide view is just plain wrong about the way these captured electrons affect the behavior of hardware components such as flash memory cells.

Common 'oxygen sponge' catalyst soaks up hydrogen too, neutron spectroscopy reveals

A workhorse catalyst of vehicle exhaust systems — an “oxygen sponge” that can soak up oxygen from air and store it for later use in oxidation reactions — may also be a “hydrogen sponge,” scientists have discovered.

NASA Pays Tribute to Early Space Pioneer Richard Gordon

The following is a statement from acting NASA Administrator Robert Lightfoot on the passing of former NASA astronaut Richard Gordon:

Color me purple, or red, or green, or ...

Scientists have, for the first time, developed nanoscale devices that divide incident white light into its component colors based on the direction of illumination, or directs these colors to a predetermined set of output angles.

Two-dimensional materials unlock the path to ultra-low-power transistors

An international team of scientists has discovered a new route to ultra-low-power transistors using a graphene-based composite material.

Need entangled atoms? Get 'Em FAST! with NIST's new patent-pending method

Physicists have come up with a way to link a group of atoms' quantum mechanical properties among themselves far more quickly than is currently possible, potentially providing a tool for highly precise sensing and quantum computer applications.

Fireworks from atoms at ultra-low temperatures

Scientists aren't normally treated to fireworks when they discover something about the universe. But a team of researchers found a show waiting for them at the atomic level -- along with a new form of quantum behavior.

Improving sensor accuracy to prevent electrical grid overload

Electrical physicists from Czech Technical University have provided additional evidence that new current sensors introduce errors when assessing current through iron conductors. It's crucial to correct this flaw in the new sensors so that operators of the electrical grid can correctly respond to threats to the system. The researchers show how a difference in a conductor's magnetic permeability, the degree of material's magnetization response in a magnetic field, affects the precision of new sensors. They also provide recommendations for improving sensor accuracy.

Measuring atoms for better navigation and mineral detection

Better navigation systems and tracking of minerals and water may be the result of a new discovery by physicists studying atom measurement devices.

New quantum materials offer novel route to 3-D electronic devices

Researchers have shown how the principles of general relativity open the door to novel electronic applications such as a three-dimensional electron lens and electronic invisibility devices.
