: MIT researchers have found that an alloy material called InGaAs could be suitable for high-performance computer transistors. If operated at high-frequencies, InGaAs transistors could one day rival silicon. This image shows a solid state memory wafer traditionally made of silicon.

Ultra-thin gold lamellae drastically amplify the incoming terahertz pulses (red) in the underlying graphene layer, enabling efficient frequency multiplication. Credit: HZDR/Werkstatt X On the electromagnetic spectrum, terahertz light is located between infrared radiation and microwaves. It holds enormous potential for tomorrow’s technologies: Among other things, it might succeed 5G by […]

ANIMATION Shifting Gears Toward Chemical Machines The gear is one of the oldest mechanical tools in human history1 and led to machines ranging from early irrigation systems and clocks, to modern engines and robotics. For the first time, researchers at the University of Pittsburgh Swanson School of Engineering have utilized a […]

An electrical current excites the superposition of two magnons with linear polarization (indicated by the red and blue arrows). Subsequently, energy is transported through the antiferromagnetic insulator. This can be detected as electrical voltage.

An HZB team has published a report in the journal Science on the development of its current world record […]

A solution to the growing clean drinking water availability problem is direct solar steam generation technology, which can remove harmful soluble pollutants from water. Credit: Lei Miao from SIT Scientists review some of the research behind a technology that could cauterize a growing global drinking water crisis. A nascent but […]

Scientists at The University of Tokyo use computer simulations to model the effects of elemental composition on the glass-forming ability of metallic mixtures, which may lead to tough, electroconductive glasses.

ANIMATION In a new realm of materials, PhD student Thanh Nguyen uses neutrons to hunt for exotic properties that could power real-world applications. Thanh Nguyen is in the habit of breaking down barriers. Take languages, for instance: Nguyen, a third-year doctoral candidate in nuclear science and engineering (NSE), wanted “to […]

Pictural representation of the molecule-based magnet and its magnetic properties. Credit: Rodolphe Clérac Magnets are to be found everywhere in our daily lives, whether in satellites, telephones or on fridge doors. However, they are made up of heavy inorganic materials whose component elements are, in some cases, of limited availability. […]

Based on different commercially available raw materials (e.g., TiO2-mica, Fe2O3-mica), a variety of all-natural bioinspired structural materials with different colors can be fabricated.
