Switching off superconductivity solves a decade-old mystery in magic-angle graphene
Researchers at the University of Manchester's National Graphene Institute, led by lead author Julien Barrier and corresponding authors Professor Sir Andre Geim and Professor Alexey Berdyugin of the National University of Singapore, together with contributing...
Quantum oscillations defy expectations in this exotic material
Scientists have uncovered an unusual form of electron behavior in zirconium pentatelluride, a quantum material that can act as both an insulator and a conductor. Under temperatures near absolute zero and magnetic fields reaching 60 tesla, electrons produced quantum...
Wafer-scale porous graphene network shows room-temperature ferromagnetism
Researchers at Shenzhen University, the Japan Atomic Energy Agency, the National Institutes for Quantum Science and Technology (QST), the University of Tokyo, the University of Science and Technology of China, Xi'an Jiaotong University, Shenzhen Technology University...
Switchable graphene nanoribbon flips its twist direction using a chiral solvent
Researchers at Nagoya University have synthesized a helical graphene nanoribbon (GNR) whose handedness can be switched on demand. The team built what they call a poly[4]helicene nanoribbon, a ladder-type polymer made entirely of [4]helicene subunits, and showed that...
Scientists just overturned a century-old physics assumption
Scientists at Carnegie Mellon University have discovered an unexpected form of the Hall effect, overturning the long-held assumption that this electrical response only appears when a magnetic field points perpendicular to a material. Beyond expanding a century-old...
Sparc Technologies completes first commercial delivery of ecosparc® graphene additive to Tier 1 coatings customer
Sparc Technologies has completed the first commercial delivery of its ecosparc® graphene additive to a Tier 1 coatings customer, fulfilling a 160kg order from the company's production facility in Adelaide, South Australia, for use in a high-performance protective...
Faint far-infrared light drives insulator-to-metal transition in magic-angle graphene
Researchers at the National University of Singapore, the Center for Neurophysics and Neuromorphic Technologies (Moscow), Queen's University (Kingston), HSE University (Moscow), the National Institute for Materials Science (Tsukuba) and the University of Manchester,...
Gate-tunable spin bands in graphene point toward low-voltage spin transistors
Researchers at the National University of Singapore (NUS), led by Assistant Professor Ahmet Avsar of the university's Centre for Advanced 2D Materials, have combined a record-fidelity graphene spin-transport platform with magnetic-proximity band engineering to move...
Some signs of quantum gravity may be an illusion
Quantum mechanics and Einstein’s theory of gravity explain almost everything we see in nature, yet physicists still do not know how to unite them. A new theoretical framework suggests that some experiments that appear to show gravity behaving quantum mechanically may...
Graphene improves ZnO:Sm nanocomposite dielectric conductivity by up to seven orders of magnitude
Researchers at Romania's National Institute for Research and Development in Microtechnologies (IMT-Bucharest), working with the "Petru Poni" Institute of Macromolecular Chemistry in Iasi, the Horia Hulubei National R&D Institute for Physics and Nuclear...
