Researchers at Lawrence Berkeley National Laboratory and University of California, Berkeley created an ultrathin magnet that operates at room temperature. They synthesized the new 2D magnet—called a cobalt-doped van der Waals zinc-oxide magnet—from a solution of graphene oxide, zinc, and cobalt.
Massachusetts Institute of Technology physicists observed signs of a rare type of superconductivity in magic-angle twisted trilayer graphene. They report that the material exhibits superconductivity at magnetic fields of up to 10 Tesla, which is three times higher than what the material is predicted to endure if it were a conventional superconductor.
Researchers increased the photovoltaic effect of ferroelectric crystals by a factor of 1,000 by arranging layers of barium titanate, strontium titanate and calcium titanate periodically in a lattice.
Incheon National University researchers developed a machine learning-based approach that can more accurately estimate the output of photovoltaic systems than similar algorithms, easing their integration into existing power grids.
University of Texas at Dallas researchers demonstrated that a technique called photonic curing can be used to manufacture thin films used in flexible electronics 1 million times faster than traditional methods.
Researchers at Sandia National Laboratories designed a new class of molten sodium batteries for grid-scale energy storage. Commercially available molten sodium batteries typically operate at 520-660°F. Sandia’s new battery operates at a much cooler 230°F.
Researchers from the National Korea Maritime and Ocean University found that embedding manganese selenide anodes in a 3D carbon nanosheet matrix is an innovative, simple, and low-cost means of reducing drastic volume expansion while improving the energy density of these batteries.
Massachusetts Institute of Technology researchers assessed the long-term economic and environmental impacts of carbon capture and storage (CCS) deployment. They determined that absent industrial CCS deployment, the global costs of implementing the 2°C policy are higher by 12% in 2075 and 71% in 2100, relative to policy costs with CCS.
Researchers in China developed a way to create intricate 3D structures out of glass by mimicking the ancient art of origami. The technique involves curing a silica nanoparticle-filled liquid precursor into a polymer composite sheet, which is cut into the desired shape.
An all-Italian working group led by Snam, RINA and Bormioli will test the use of hydrogen blended with natural gas in glass melting furnaces to lower their carbon dioxide emissions.
Researchers developed a machine learning-based model to predict the characteristics of bonded systems. Using the density of states of the individual component reactants, they achieved accurate predictions of the binding energy, bond length, number of covalent electrons, and Fermi energy.
Researchers from the Institute of Materials Science of Barcelona proposed a new theory to explain the transparency of metal oxides. They believe coupling of electronics with the crystal lattice causes an increase in the effective mass of the electrons, which means the material cannot follow the oscillations of the electric light field and lets light pass through.
