- 18/03/2021 Nano-gate: Researchers create voltage-controlled nanopores that can trap particles as they try to pass through Scientists from the Institute of Scientific and Industrial Research at Osaka University fabricated nanopores in silicon dioxide, that were only 300 nm, in diameter surrounded by electrodes. These nanopores could prevent particles from entering just by applying a voltage, which may permit the development of sensors that can detect very small concentrations of target molecules, as well as next-generation DNA sequencing technology.

- 11/03/2021 Subtle quantum phenomenon found to alter chemical reactivity for the first time A new frontier has been discovered in how quantum phenomena control chemical reactivity. By colliding beams of two different reactants, a Chinese team spanning three universities has shown that the outcome can only be explained by interactions between electron spin and orbital angular momentum. This is the first time that electronic angular momentum has been found to affect such reactions, explains Xueming Yang from South University of Science and Technology in Shenzhen. The finding is ‘very special’, adds his colleague Zhigang Sun from the Dalian Institute of Chemical Physics.
- 09/03/2021 Taking 2-D materials for a spin Scientists from the University of Tsukuba and a scientist from the Institute of High Pressure Physics detected and mapped the electronic spins moving in a working transistor made of molybdenum disulfide. This research may lead to much faster computers that take advantage of the natural magnetism of electrons, as opposed to just their charge.
- 04/03/2021 A New Class of Superconductors: Commonly Mistaken Name Leads to Discovery A new theory that could explain how unconventional superconductivity arises in a diverse set of compounds might never have happened if physicists Qimiao Si and Emilian Nica had chosen a different name for their 2017 model of orbital-selective superconductivity.
- 02/03/2021 Quantum quirk yields giant magnetic effect, where none should exist In a twist befitting the strange nature of quantum mechanics, physicists have discovered the Hall effect -- a characteristic change in the way electricity is conducted in the presence of a magnetic field -- in a nonmagnetic quantum material to which no magnetic field was applied.
