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 ...

In search of Weyl semimetals

Imagine how much you could accomplish if the circuits in your laptop and cell phone worked 10 times faster, and your battery lasted 10 times longer, than they do now.

How molecules interact with a laser field

When molecules interact with the oscillating field of a laser, an instantaneous, time-dependent dipole is induced. This very general effect underlies diverse physical phenomena such as optical tweezers, for which Arthur Ashkin ...

Saving energy by taking a close look inside transistors

Researchers at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) have developed a simple yet accurate method for finding defects in the latest generation of silicon carbide transistors. This will speed up the process ...

A step closer to a data superhighway for future internet

An international team of researchers led by ANU is helping to build a safe data superhighway for the highly anticipated quantum internet, which promises a new era of artificial intelligence and ultra-secure communication.

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.

Optoacoustic microscopy at multiple discrete frequencies

Optoacoustic imaging powered by short bursts of continuous wave (CW) lasers can stimulate the emission of ultrasound waves inside an animal or in human subjects. The method can noninvasively capture blood flow and produce ...

Artificial intelligence detects the presence of viruses

Many biosensing applications rely on characterization of specific analytes such as proteins, viruses and bacteria, among many other targets, which can be accomplished by using micro- or nano-scale particles. In such biosensors, ...
