How it works: illustration of the quantum twisting microscope in action. Electrons tunnel from the probe (inverted pyramid at the top) to the sample (bottom) in several places at once (green vertical lines) in a quantum-coherent manner.

Like Mushrooms for Plastics…
Credit: VTT Technical Research Centre of Finland Topics: Biology, Biotechnology, Chemistry, Materials Science, Mechanical Engineering A research group from VTT Technical Research Center of Finland has unlocked the secret behind the extraordinary mechanical properties and ultra-light weight of certain fungi. The complex architectural design of mushrooms could be mimicked and used to create new materialsContinue reading “Like Mushrooms for Plastics…”
Graphullerene…
Credit: Nicoletta Barolini Topics: Chemistry, Graphene, Materials Science, Modern Physics, Nanotechnology Graphullerene, an atom-thin material made of linked fullerene subunits, gives scientists a new form of modular carbon to play with. Carbon, in its myriad forms, has long captivated the scientific community. Besides being the primary component of all organic life on earth, material formsContinue reading “Graphullerene…”
Chip Act and Wave Surfing…
Massive subsidies to regain the edge of the US semiconductor industry will not likely succeed unless progress is made in winning the global race of idea flow and monetization. Topics: Applied Physics, Chemistry, Computer Science, Electrical Engineering, Semiconductor Technology Intelligent use of subsidies for winning the global idea race is a must for gaining andContinue reading “Chip Act and Wave Surfing…”
CEM for SEI…
Panel A shows how the native SEI on Li metal is passivating to nitrogen gas, which means that no reactivity with Li metal is possible. Panel B shows that a proton donor like Ethanol will disrupt the SEI passivation and enable Li metal to react with nitrogen species. Panel C describes 3 potential mechanisms throughContinue reading “CEM for SEI…”

Topics: Chemistry, Nobel Laureate, Nobel Prize The Nobel Prize in Chemistry 2022 was awarded jointly to Carolyn R. Bertozzi, Morten Meldal, and K. Barry Sharpless “for the development of click chemistry and bioorthogonal chemistry” The 2022 Nobel Prize in Chemistry is about making the difficult simple. Barry Sharpless and Morten Meldal have laid the foundations forContinue reading “The Nobel Prize in Chemistry 2022…”
5 Elements…
Topics: Chemistry, Nobel Laureate, Nobel Prize Currently, there are 118 elements on the periodic table. If a new element is discovered, naming it involves several factors. Elements can be named after how they were obtained, their attributes, the compound they were isolated from, and places they were discovered. However, they can also be named after the peopleContinue reading “5 Elements…”
WASP-39b and CO2…
Topics: Astrophysics, Chemistry, ESA, Exoplanets, James Webb Space Telescope, NASA The James Webb Space Telescope — already famous for its mesmerizing images of the cosmos — has done it again. The telescope has captured the first unambiguous evidence of carbon dioxide in the atmosphere of a planet outside the Solar System. The finding not only provides tantalizingContinue reading “WASP-39b and CO2…”
Perovskite and Maxima…
Topics: Alternate Energy, Applied Physics, Battery, Chemistry, Civilization, Climate Change A longstanding explanation for why perovskite materials make such good solar cells has been cast into doubt thanks to new measurements. Previously, physicists ascribed the favorable optoelectronic properties of lead halide perovskites to the behavior of quasiparticles called polarons within the material’s crystal lattice. Now,Continue reading “Perovskite and Maxima…”
