Magnetic particle imaging is a new, up-and-coming, safe and highly sensitive tracer imaging technique that works by detecting superparamagnetic iron oxide nanoparticles with high image contrast (that is, no background tissue signal). The technique, which does not use any ionizing radiation, can be used to image anywhere inside the body, which means that it could […]

Graphene (a sheet of carbon just one atom thick) could be used to coat smart contact lenses and help protect eyes from electromagnetic radiation and dehydration, according to new work by researchers at Seoul National University, Graphene Square Inc and Interojo Inc. The contact lenses could be used in various healthcare and wearable technologies in […]

Copper-based interconnects are widely employed in integrated circuits in a variety of semiconductor technologies and applications but they are fast reaching their limits. This is because their resistivity increases and current-carrying capacity decreases as they are made smaller. A team of researchers at the University of California at Santa Barbara has now shown that intercalation-doped […]

The pesky poly(methyl methacrylate) (PMMA) residues left from transferring graphene grown by chemical vapour deposition (CVD) have remained a challenge for maximising this potentially scalable approach to high-quality graphene production. Now researchers at West Virginia University have demonstrated a simple electrolytic cleaning method for removing PMMA residues that greatly reduces impairments to the electronic properties […]

Thanks to density functional theory-based calculations, researchers at the Chungnam National University in Korea and the Brookhaven National Laboratory in the US have been able to test

Magnetic skyrmions (quasiparticle magnetic spin configurations with a whirling vortex-like structure) could be used in future spintronics applications, such as racetrack memories and logic devices. Now, a team of researchers from Germany, the US and Japan have observed the “skyrmion Hall effect” in a magnetic material at room temperature for the first time. The skyrmions […]

Researchers at the University of Michigan in the US have designed novel vaccine nanodiscs that could be used to treat cancer. The lipoprotein-mimicking nanostructures coupled with antigen peptides and adjuvants efficiently deliver vaccine components to lymphoid tissues and so are significantly better than conventional vaccines in this context. They could herald a new era of […]

Physicists at the Niels Bohr Institute at the University of Copenhagen in Denmark and Microsoft’s Station Q Copenhagen laboratory have produced and detected Majorana “zero modes” with unprecedented clarity in a quantum-dot hybrid-nanowire system. These modes, which are formed by delocalized states of electrons with topological properties might be used as qubits in fault-tolerant quantum […]

  There are some strange uses for a spent tea bag after it’s made your cuppa, but work recently published in Scientific Reports really takes the biscuit. A group of researchers in Korea have managed to demonstrate an enhanced carbon anode structure from waste tea leaves that could be a path to cheap, high-capacity lithium […]
