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...
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...
New graphene oxide-based catalyst boosts zinc-air battery performance
Researchers at CICATA-Legaria, the National Laboratory for Energy Conversion and Storage at Mexico's Instituto Politécnico Nacional (IPN) in Mexico City, have developed a composite of pyridine-coordinated transition-metal nitroprussides and reduced graphene oxide...
Biodegradable graphene-oxide platform senses neurotransmitters, modulates brain astrocyte signaling
Researchers at Italy's National Research Council (CNR) - specifically its Institute for Organic Synthesis and Photoreactivity (Cnr-Isof) and Institute of Nanostructured Materials (Cnr-Ismn) - working with Ca' Foscari University of Venice, the University of Ferrara,...
Premier Graphene, HGI deliver second batch of tactical belts under Mexico’s SEDENA contract
Premier Graphene (OTC: BIEI) and joint venture partner HGI Industrial Technologies have delivered a second batch of tactical belts to the Dirección General de Fábrica de Vestuario y Equipo (FAVE), a division of Mexico's Secretaría de la Defensa Nacional (SEDENA),...
Scientists switch on a strange new form of magnetism in an ultrathin material
Scientists have found a surprising way to potentially switch on an unusual form of magnetism in ruthenium dioxide, a material that normally appears nonmagnetic. When the material was made into an ultrathin film only a few atomic layers thick and placed under...
Newspaper cellulose enables tap-water processing of e-waste graphite into graphene
Researchers at Dublin City University (DCU), led by materials scientist Conor Boland, have shown that graphene can be produced from electronic-waste graphite using little more than a kitchen blender, waste newspaper and ordinary tap water, extending the group's...
Argo Graphene amends $1 million financing, advances STREAM graphene commercialization
Argo Graphene Solutions Corp. (CSE: ARGO), developer of the STREAM™ graphene production platform, has amended the terms of the non-brokered private placement it announced earlier this month. Under the revised terms, Argo now proposes to issue up to 1,250,000 units...
Atomic catalyst unlocks the hidden value of plant waste
Scientists have created a highly efficient catalyst that breaks down stubborn lignin from plant waste into useful chemicals under relatively mild conditions. By revealing exactly how the catalyst works at the atomic level, the discovery could help turn forestry and...
