Nano Laser…

Topics: Applied Physics, Bose-Einstein Condensate, Lasers, Nanotechnology, Optics Physicists have taken a step towards realizing the smallest-ever solid-state laser by generating an exotic quantum state known as a Bose-Einstein condensate (BEC) in quasiparticles consisting of both matter and light. Although the effect has so far only been observed at ultracold temperatures in atomically thin crystalsContinue reading “Nano Laser…”

Graphene Beam Splitter…

Topics: Graphene, Interferometry, Nanotechnology, Quantum Computer A graphene-based “beam splitter” for electronic currents has been built by researchers in France, South Korea, and Japan. Created by Preden Roulleau at the University of Paris and colleagues, the tunable device’s operation is directly comparable that of an optical interferometer. The technology could soon enable allow electron interferometry to beContinue reading “Graphene Beam Splitter…”

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…”

Kondo Mimic…

Topics: Magnetism, Materials Science, Nanotechnology A new type of quasiparticle – dubbed the “spinaron” by the scientists who discovered it – could be responsible for a magnetic phenomenon that is usually attributed to the Kondo effect. The research, which was carried out by Samir Lounis and colleagues at Germany’s Forschungszentrum Jülich, casts doubt on current theories of theContinue reading “Kondo Mimic…”

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…”

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….”

Quasiparticles, and Graphene…

Topics: Fermions, Graphene, Nanotechnology, Quantum Mechanics Researchers at the University of Manchester in the UK have identified a new family of quasiparticles in superlattices made from graphene sandwiched between two slabs of boron nitride. The work is important for fundamental studies of condensed-matter physics and could also lead to the development of improved transistors capableContinue reading “Quasiparticles, and Graphene…”

Integrated Nanodiamonds…

Topics: Nanotechnology, Quantum Computer, Quantum Mechanics, Semiconductor Technology (Nanowerk News) Physicists at Münster University have succeeded in fully integrating nanodiamonds into nanophotonic circuits and at the same time addressing several of these nanodiamonds optically. The study creates the basis for future applications in the field of quantum sensing schemes or quantum information processors. The resultsContinue reading “Integrated Nanodiamonds…”

Diamond Nanoneedles…

Topics: Materials Science, Modern Physics, Nanotechnology, Semiconductor Technology If you ever manage to deform a diamond, you’re likely to break it. That’s because the hardest natural material on Earth is also inelastic and brittle. Two years ago, Ming Dao (MIT), Subra Suresh (Nanyang Technological University in Singapore), and their collaborators demonstrated that when bulk diamonds are etched into fine,Continue reading “Diamond Nanoneedles…”

The Power of ASM…

Topics: Alternate Energy, Applied Physics, Atomic-Scale Microscopy, Nanotechnology When Ondrej Krivanek first considered building a device to boost the resolution of electron microscopes, he asked about funding from the U.S. Department of Energy. “The response was not positive,” he says, laughing. He heard through the grapevine that the administrator who held the purse strings declaredContinue reading “The Power of ASM…”
