UV fluorescence examination. Credit: The authors Analyses of the materials in the scrolls helps put the object into a historical context and guides conservators in future restoration efforts. A picture may be worth a thousand words, but capturing multiple images of an artifact across the electromagnetic spectrum can tell a […]

A research team led by Northwestern engineers and Argonne National Laboratory researchers have uncovered new findings into the role of ionic interaction within graphene and water. The insights could inform the design of new energy-efficient electrodes for batteries or provide the backbone ionic materials for neuromorphic computing applications. Known for possessing extraordinary […]

: 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.
