Scrofulous Signaling…

Topics: Applied Physics, Electrical Engineering, Materials Science, Optics ABSTRACT We present results of near-field radio-frequency (RF) imaging at micrometer resolution using an ensemble of nitrogen-vacancy (NV) centers in diamond. The spatial resolution of RF imaging is set by the resolution of an optical microscope, which is markedly higher than the existing RF imaging methods. HighContinue reading “Scrofulous Signaling…”

Smart Foam…

Topics: Biology, Biotechnology, Materials Science, Polymer Science, Robotics SINGAPORE, July 6 (Reuters) – Singapore researchers have developed a smart foam material that allows robots to sense nearby objects, and repairs itself when damaged, just like human skin. Artificially innervated foam, or AiFoam, is a highly elastic polymer created by mixing fluoropolymer with a compound thatContinue reading “Smart Foam…”

Kagome Metal…

Topics: Condensed Matter Physics, Materials Science, Superconductors Researchers at the Chinese Academy of Sciences have found evidence for an unusual superconducting state in CsV3Sb5, a so-called Kagome metal that exhibits exotic electronic properties. The finding could shed new light on how superconductivity emerges in materials where phenomena such as frustrated magnetism and intertwined orders playContinue reading “Kagome Metal…”

Recycled Plastics, Sustainable Fabrics…

Topics: Ecology, Environment, Green Tech, Materials Science Polyethylene is one of the most common plastics in the world, but it is seldom found in clothing because it cannot absorb or carry away water. (Imagine wearing a plastic bag – you would feel very uncomfortable very quickly.) Now, however, researchers in the US have developed aContinue reading “Recycled Plastics, Sustainable Fabrics…”

Colloidal Quantum Dots…

Topics: Energy, Materials Science, Nanotechnology, Quantum Mechanics, Solar Power ABSTRACTSolution-processed colloidal quantum dot (CQD) solar cells are lightweight, flexible, inexpensive, and can be spray-coated on various substrates. However, their power conversion efficiency is still insufficient for commercial applications. To further boost CQD solar cell efficiency, researchers need to better understand and control how charge carriersContinue reading “Colloidal Quantum Dots…”

Snapping Polymer Discs…

Topics: Chemistry, Polymer Science, Materials Science, Research A polymer-based gel made by researchers in the US and inspired by the Venus flytrap plant can snap, jump and “reset” itself autonomously. The new self-propelled material might have applications in micron-sized robots and other devices that operate without batteries or motors. “Many plants and animals, especially smallContinue reading “Snapping Polymer Discs…”

Einsteinium Chemistry…

Topics: Chemistry, Einstein, Materials Science, Research To date, researchers have created more than two dozen synthetic chemical elements that don’t exist naturally on Earth. Neptunium (atomic number Z = 93) and plutonium (Z = 94), the first two artificial elements after naturally occurring uranium, are produced in nuclear reactors by the thousands of kilograms. But the accessibility ofContinue reading “Einsteinium Chemistry…”

Nanoscale Knudsen Flow…

Topics: Fluid Mechanics, Materials Science, Nanofluidics, Nanotechnology Gases flow through a porous membrane at ultrahigh speeds even when the pores’ diameter approaches the atomic scale. This finding by researchers at the University of Manchester in the UK and the University of Pennsylvania in the US shows that the century-old Knudsen description of gas flow remainsContinue reading “Nanoscale Knudsen Flow…”

3D Hydrogel Polymers…

Topics: Chemistry, Materials Science, Polymer Science AbstractHydrogel-polymer hybrids have been widely used for various applications such as biomedical devices and flexible electronics. However, the current technologies constrain the geometries of hydrogel-polymer hybrid to laminates consisting of hydrogel with silicone rubbers. This greatly limits functionality and performance of hydrogel-polymer–based devices and machines. Here, we report aContinue reading “3D Hydrogel Polymers…”

2020 Nano Highlights….

Topics: Biology, Materials Science, Nanotechnology, Research Snake vision inspires pyroelectric material design Bioinspiration and biomimicry involve studying how living organisms do something and using that insight to develop new technologies. Pit vipers have two special organs on their heads called loreal pits that allow them to “see” the infrared radiation given off by their warm-bloodedContinue reading “2020 Nano Highlights….”
