OPVs…

V. ALTOUNIAN/SCIENCE Topics: Alternate Energy, Applied Physics, Chemistry, Materials Science, Solar Power As ultrathin organic solar cells hit new efficiency records, researchers see green energy potential in surprising places. In November 2021, while the municipal utility in Marburg, Germany, was performing scheduled maintenance on a hot water storage facility, engineers glued 18 solar panels toContinue reading “OPVs…”

The Nobel Prize in Chemistry 2022…

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…”

Helium and Ukraine…

Topics: Chemistry, Instrumentation, Nuclear Magnetic Resonance, Physics, Research Scientists who need the gas face tough choices in the face of reduced supply and spiking prices. Helium supplies, already dicey, got worse this past week when production shut down in Arzew, Algeria. The curtailment joins ongoing disruptions in supplies from Russia and the US Federal Helium Reserve as wellContinue reading “Helium and Ukraine…”

Cobalt and Caveats

Topics: Battery, Chemistry, Climate Change, Environment, Politics KASULO, Democratic Republic of Congo — A man in a pinstripe suit with a red pocket square walked around the edge of a giant pit one April afternoon where hundreds of workers often toil in flip-flops, burrowing deep into the ground with shovels and pickaxes. His polished leatherContinue reading “Cobalt and Caveats”

Lithium and Caveats…

Topics: Alternate Energy, Battery, Biofuels, Chemistry, Climate Change, Environment California and the Biden administration are pushing incentives to make the United States a global leader in a market that’s beginning to boom: the production of lithium, the lightweight metal needed for the batteries of electric vehicles, and for the storage of renewable energy from powerContinue reading “Lithium and Caveats…”

Kilonovas and Gold…

Topics: Astronomy, Astrophysics, Chemistry, Materials Science, Neutron Stars The amounts of heavy elements such as gold created when black holes merge with neutron stars have been calculated and compared with the amounts expected when pairs of neutron stars merge. The calculations were done by Hsin-Yu Chen and Salvatore Vitale at the Massachusetts Institute of Technology and Francois Foucart at the UniversityContinue reading “Kilonovas and Gold…”

Quantum Exorcism…

Topics: Chemistry, History, Materials Science, Quantum Mechanics, Thermodynamics Thermodynamics is a strange theory. Although it is fundamental to our understanding of the world, it differs dramatically from other physical theories. For that reason, it has been termed the “village witch” of physics.1 Some of the many oddities of thermodynamics are the bizarre philosophical implications of classicalContinue reading “Quantum Exorcism…”
