In 2018, a discovery in materials science sent shock waves throughout the community. A team showed that stacking two layers of graphene—a honeycomb-like layer of carbon extracted from graphite—at a precise “magic angle” turned it into a superconductor, says Ritesh Agarwal of the University of Pennsylvania.

Newly developed material can suppress thermal runaway in batteries
A team of engineers and materials scientists at LG Chem, Korea’s largest chemical company, has developed a material that they claim could greatly reduce the risk of thermal runaway and resulting fires in batteries. In their paper published in the journal Nature Communications, the group describes how they developed the material and how well it has worked during testing.
Over the past several years, consumers have witnessed or have heard about batteries in smartphones or cars catching on fire. These fires, it has been found, result from thermal runaway, which is where the anode and cathode inside a battery come too close together, or worse, actually touch.
The result is a short, which generates heat, and results soon thereafter in a fire. In this new effort, the team at LG has developed a thin material that, when placed between the cathode and collector, prevents thermal runaway.

Glow in the dark gemstones show the jewellery industry that laboratory-grown crystals can shine bright
For the last three years,…
A UWE Bristol researcher hopes to revolutionise the jewellery industry and its supply chains with the creation of unique gemstone and jewellery designs with ground-breaking properties — including the world’s first single stone glow-in-the-dark manmade crystal.
For the last three years, award-winning jewellery designer Sofie Boons, who’s a Crafts Council Research Fellow at the university’s Centre for Print Research (CFPR), has been undertaking tests on the viability, limitations and use of innovative and experimentally grown crystals in the production of contemporary jewellery.
Working in collaboration with Swiss company BREVALOR Sarl and using their new material ‘BRG’, Sofie has successfully facetted a single stone out of the material – offering jewellery designers a crystal which is not only brilliant when seen in daylight, but illuminates when seen in the dark.
Orbitronics: New Material Property Could Advance Energy-Efficient Tech
Yet despite the attraction of OAM monopoles for orbitronics, until this latest study, they have remained a theoretical dream.
Hedgehogs hide between theory and experiment.
To observe them experimentally, hope has lain with a technique known as Circular Dichroism in Angle-Resolved Photoemission Spectroscopy, or CD-ARPES, using circularly polarised X-rays from a synchrotron light source. Yet a gap between theory and experiment has in the past hindered researchers from interpreting the data. “Researchers may have had the data, but the evidence for OAM monopoles was buried in it,” says Schüler.
Why we are finally within reach of a room-temperature superconductor
A practical superconductor would transform the efficiency of electronics. After decades of hunting, several key breakthroughs are inching us very close to this coveted prize.
Simultaneous detection of uranium isotopes and fluorine advances nuclear nonproliferation monitoring
Combining two techniques, analytical chemists at the Department of Energy’s Oak Ridge National Laboratory have become the first to detect fluorine and different isotopes of uranium in a single particle at the same time. Because fluorine is essential for converting uranium into a form suitable for enrichment, spotting both elements together may help inspectors of the International Atomic Energy Agency, or IAEA, determine the intended use of a nuclear material.
Researchers develop new p-type semiconductor materials for next-gen displays
A group of Korean researchers have recently succeeded in developing new p-type semiconductor materials and thin-film transistors that will lead the innovation of the semiconductor industry. These new discoveries are expected to be widely utilized to improve the overall performance of next-gen displays and ultra-low power semiconductor devices.

Danish physicists make monumental quantum mechanics discovery
The research was conducted at the Danish National Research Foundation’s “Center of Excellence for Hybrid Quantum Networks (Hy-Q)” and is a collaboration between Ruhr University Bochum in Germany and the University of Copenhagen’s Niels Bohr Institute.
