Graphene Nanomesh. Credit: Hiroshi Mizuta, JAIST Researchers at Japan advanced institute of science and technology (JAIST) have successfully fabrication the suspended graphene nanomesh in a large area by the helium ion beam microscopy. 6nm diameter nanopores were pattern on the 1.2 um long and 500 nm wide suspended graphene uniformly. By systematically […]

Researchers at Princeton have discovered superconducting currents traveling along the outer edges of a superconductor with topological properties, suggesting a route to topological superconductivity that could be useful in future quantum computers. The superconductivity is represented by the black center of the diagram indicating no resistance to the current flow. […]

A schematic and electron microscope cross-section show the structure of an integrated, solar-powered catalyst to split water into hydrogen fuel and oxygen. The module developed at Rice University can be immersed into water directly to produce fuel when exposed to sunlight. Credit: Illustration by Jia Liang/Rice University ‘Artificial leaf’ concept […]

An artistic impression of the metasurface laser to produce super-chiral twisted light with OAM up to 100. Credit: Wits University Laser opens up a new world of applications using optical control of physical objects. Researchers have demonstrated the world’s first metasurface laser that produces “super-chiral light”: light with ultra-high angular […]

A hydrogel can cool off electronics and generate electricity from their waste heat. Scale bar, 2 cm. Credit: Adapted from Nano Letters 2020, DOI: 10.1021/acs.nanolett.0c00800 Using electronic devices for too long can cause them to overheat, which might slow them down, damage their components or even make them explode or […]

On this illustrated silicon chip (grey), electrical data (white) travels through the Mach-Zehnder interferometer (MZI) based electro-optical modulators, encoding electrical data into the optical domain by means of tunable plasmonic ITO-based phase shifters (golden patches atop both MZI sections) capable of operating at multiple wavelengths of light in the telecommunication-relevant […]

Highly porous programmable sponge for clean energy storage. Credit: Northwestern University Tremendous amounts of hydrogen and methane can be stored in nanoscopic pores. A research team led by Northwestern University has designed and synthesized new materials with ultrahigh porosity and surface area for the storage of hydrogen and methane for fuel cell-powered […]

Made from curved gold-cysteine nanosheets that all twist in the same direction, the spiky nanoparticle achieved the highest complexity measured. It absorbs UV light and emits twisted light in the visible part of the spectrum. Credit: Wenfeng Jiang, Kotov Lab, University of Michigan Synthetic microparticles more intricate than some of […]

With wall thicknesses of about 160 nanometers, a closed-cell, plate-based nanolattice structure designed by researchers at UCI and other institutions is the first experimental verification that such arrangements reach the theorized limits of strength and stiffness in porous materials.
