- Warped nanographene at odds with aromaticity 23/03/2021 Scientists discover a π-electron circuit with an odd number of electrons in a polycyclic system
- Nano-gate: Researchers create voltage-controlled nanopores that can trap particles as they try to pass through 18/03/2021 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.
- Stable 2D boron material created for the first time 16/03/2021 Atomically thin boron stabilised by hydrogenating the material to create borophane
- Subtle quantum phenomenon found to alter chemical reactivity for the first time 11/03/2021 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.
- Taking 2-D materials for a spin 09/03/2021 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.
- A New Class of Superconductors: Commonly Mistaken Name Leads to Discovery 04/03/2021 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.
- Quantum quirk yields giant magnetic effect, where none should exist 02/03/2021 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.
- Nanoscópio da UFMG possibilita compreender estrutura que torna grafeno supercondutor 25/02/2021 Artigo que ganhou capa na Nature atesta capacidade do instrumento, que rendeu nove patentes e já pode ter sua tecnologia transferida para a indústria
- Beyond qubits: Next big step to scale up quantum computing 23/02/2021 Researchers have invented a device that operates at 40 times colder than deep space to directly control thousands of qubits, the building blocks of quantum computers.
- Scientists manipulate magnets at the atomic scale 19/02/2021 Fast and energy-efficient future data processing technologies are on the horizon after an international team of scientists successfully manipulated magnets at the atomic level.
- Vibrating 2D materials 18/02/2021 Two-dimensional materials hold out hope for many technical applications. An international research team now has determined for the first time how strongly 2D materials vibrate when electronically excited with light.
