Jan. 24, 2023 — It was believed that Hall thrusters, an efficient kind of electric propulsion widely used in orbit, need to be large to produce a lot of thrust. Now, a new study suggests that smaller Hall thrusters ...
Apr. 1, 2021 — Substituting the inefficient glazing areas of buildings with energy-efficient smart glazing windows has great potential to decrease energy consumption for lighting and temperature ...
Feb. 10, 2021 — Exposure to some odorless, colorless and tasteless gases, such as nerve agents, can be toxic or even lethal. And having the ability to detect other types of vapors could save people from eating ...
Aug. 16, 2021 — Zinc traditionally has a valence of two, meaning two electrons take part in the element's chemical reaction. A new article shows that the chemistry of zinc can be fundamentally changed, making ...
Mar. 1, 2023 — Quantum effects can play an important role in chemical reactions. Physicists have now observed a quantum mechanical tunneling reaction in experiments. The observation can also be described exactly in ...
Mar. 30, 2021 — Physicists have developed an extremely thin, large-area semiconductor surface source of terahertz, composed of just a few atomic layers and compatible with existing electronic ...
July 6, 2021 — Chemical engineers have developed a machine-learning model that can predict a compound's oxidation state, a property that is so essential that many chemists argue it must be included in the ...
Sep. 15, 2022 — Researchers have gained new insights into the chemical properties of the superheavy element flerovium -- element 114 -- at the accelerator facilities of the GSI Helmholtzzentrum für ...
Dec. 7, 2023 — How heavy can an element be? An international team of researchers has found that ancient stars were capable of producing elements with atomic masses greater than 260, heavier than any element on the ...
Sep. 27, 2022 — New research advances our understanding of how the wood in our homes and offices can release formaldehyde, a potent carcinogen, at levels that can exceed certain health limits. The findings promise ...
