Giving bug-like bots a boost

Dec 17, 2021 (Nanowerk News) When it comes to robots, bigger isn’t always better. Someday, a swarm of insect-sized robots might pollinate a field of crops or search for survivors amid the rubble of a collapsed building. MIT researchers have demonstrated diminutive drones that can zip around with bug-like agility...

Scientists successfully manipulate a single skyrmion at room temperature

Dec 17, 2021 (Nanowerk News) Scientists from the RIKEN Center for Emergent Matter Science and collaborators have shown that they can manipulate single skyrmions—tiny magnetic vortices that could be used as computing bits in future ultra-dense information storage devices—using pulses of electric current, at room temperature. Skyrmions—tiny particles that can...

New smart-roof coating enables year-round energy savings

Dec 16, 2021 (Nanowerk News) Scientists have developed an all-season smart-roof coating that keeps homes warm during the winter and cool during the summer – without consuming natural gas or electricity. Research findings reported in the journal Science ("Temperature-adaptive radiative coating for all-season household thermal regulation") point to a groundbreaking...

Negative capacitance in topological transistors could reduce computing’s unsustainable energy load

Dec 16, 2021 (Nanowerk News) Australian researchers have discovered that negative capacitance could lower the energy used in electronics and computing, which represents 8% of global electricity demand. The researchers at four universities within the ARC Centre of Excellence in Future Low-Energy Electronics Technologies (FLEET) applied negative capacitance to make...

Scientists predict the rotation periods of stars

Dec 16, 2021 (Nanowerk News) The Leibniz Institute for Astrophysics Potsdam (AIP) announces the completion of a major three-publication survey of one of the richest accessible open star clusters. The final study features a method of deriving the rotation periods of stars from just one observation of the stellar activity...
