Oxygen migration at the heterostructure interface

NUS physicists have developed a methodology to control the electromigration of oxygen atoms in the buried interfaces of complex oxide materials for constructing high mobility oxide heterostructures.

More stable light comes from intentionally 'squashed' quantum dots

Intentionally 'squashing' colloidal quantum dots during chemical synthesis creates dots capable of stable, 'blink-free' light emission that is fully comparable with the light produced by dots made with more complex processes.

Spintronics 'miracle material' put to the test

When German mineralogist Gustav Rose stood on the slopes of Russia's Ural Mountains in 1839 and picked up a piece of a previously undiscovered mineral, he had never heard of transistors or diodes or had any concept of how conventional electronics would become an integral part of our daily lives. He couldn't have anticipated that the rock he held in his hand, which he named "perovskite," could be a key to revolutionizing electronics as we know them.

New dynamic probes for ions interacting with biomolecules

Pairs of negatively charged phosphate groups and positive magnesium ions represent a key structural feature of DNA and RNA embedded in water. Vibrations of phosphate groups have now been established as selective probes of such contact pairs and allow for a mapping of interactions and structure on the ultrafast time scales of molecular dynamics.

How to build a 3-D-printed particle trap with free CERN schematics

CERN is synonymous with accelerators, designed to boost particles to close to the speed of light. But what if you want to slow down a particle and hold it in place while you study it? Particle traps are devices that use electromagnetic fields to suspend particles – macroscopic or elementary – in stasis long enough to do so. At CERN, experiments such as GBAR use ion traps to capture antihydrogen ions for research.

Common frame for analyzing complex systems in physics and economics

Scientists often need to make sense of complex systems without knowing the important parameters or even without access to all the information. A collaboration of network theorists has reported a common frame for addressing these problems using only one tool.

Overtones can provide faster data communication

For the first time, researchers have succeeded in producing what are known as spin wave overtones. The technology paves the way for increasing the data transmission rate of wireless communication.

What Are FRBs? The Discovery of Mysterious Signals From the Cosmos

Scientists are finally poised to figure out the mystery of fast radio bursts, powerful energy blasts from deep space.

New technique offers rapid assessment of radiation exposure

Researchers from North Carolina State University have developed a new technique that allows them to assess radiation exposure in about an hour using an insulator material found in most modern electronics. The technique can be used to triage medical cases in the event of a radiological disaster.

Identifying lower-energy neutrinos with a liquid-argon particle detector

An experiment at the Department of Energy's Fermilab has made a significant advance in the detection of neutrinos that hide themselves at lower energies.
