Harvard University researchers developed a new method for designing large-scale metasurfaces that uses machine intelligence to generate designs automatically.
Institute for Basic Science researchers developed a bottom-up approach to construct topologically 2D carbon material atom by atom, which they dubbed “holey graphyne.”
Researchers in Japan synthesized a belt-shaped molecular nanocarbon with a twisted Möbius band topology, i.e., a Möbius carbon nanobelt. Such a twisted Möbius carbon nanobelt should manifest quite different properties and molecular motions compared to those with a normal belt topology.
Researchers from SLAC National Accelerator Laboratory, the University of British Columbia, Yale University, and others discovered that yttrium barium copper oxide’s superconductivity is intertwined in unexpected ways with another phenomenon known as charge density waves, or ripples in the density of electrons in the material.
Drexel University researchers published a design optimization system for incorporating blood vessel-like cooling networks into the packaging of carbon-fiber-based structural batteries used in electric vehicles.
Researchers developed a graphene-wrapped molecular-sieving membrane with a separation factor of 245 and a permeation coefficient of 5.8 x 106 barrers, which is more than 100 times better than that of conventional polymer separation membranes.
When an object such as a bacterium sticks to the surface of a graphene “drum” (sheets), it generates oscillations that can be detected using laser light. Researchers say the technique could be used to detect antibiotic resistance.
Researchers at Eindhoven University of Technology developed a water-responsive cholesteric liquid crystal ink and the accompanying direct ink writing procedure. They envision that this work will form the basis for 3D-printed optical sensing devices, but will also serve as a basis for the development of other responsive 3D printing inks.
Researchers from The Pennsylvania State University and Michigan Technological University demonstrated a novel mechanism that enhanced the magnitude of the piezoelectric coefficient several times higher than is normally expected for a ceramic.
A group of scientists in South Korea combined the manufacturing ease of silicon with the high-frequency performance of compound semiconductors. They stacked circuits made with these two types of materials together into a layered device with record-high radio frequency performance.
By etching nanostructures onto the surface of a thin sheet of diamond, Harvard University researchers built a highly reflective mirror that withstood, without damage, experiments with a 10-kilowatt Navy laser.
Researchers led by University of Pittsburgh used computational simulations to understand how tungsten oxide interacts with hydrogen at the molecular level and the findings were verified through lab experimentation.
Researchers harnessed the power of multiple supercomputers to map the electronic structure of more than 96,000 natural and synthetic crystalline materials. They applied sophisticated filters to determine whether and what kind of topological traits exist in each structure.
