Sooner or later all petroleum-based material used in food packaging will have to be substituted with a bio-based material. A blend of starch and other polymers forms a similarly effective protective barrier according to a study done at Karlstad University.
In 1965, a distinguished Princeton University physicist theorized that ferroelectric metals could conduct electricity in spite of not existing in nature.
A research team have confirmed the presence of chirality in nanometer-thick samples of multilayer materials with a chaotic structure.
A recent study has shown that metal atoms can directly take part in the activation of reactants, promoting catalysis of an atomically dispersed metal catalyst.
Scientists have developed a new method to regrow and remineralize dental enamel.
Physicists studying higher-order topological insulators now think the material could be used to develop semi-conductor technology or quantum computing.
Russian scientists from the Moscow Institute of Physics and Technology (MIPT), the Technological Institute for Superhard and Novel Carbon Materials (TISNCM), and the National University of Science and Technology MISIS have upgraded the design of a nuclear battery that produces power from the beta decay of nickel-63, a radioactive isotope.
Scientist David Rosenberg inspects images of a white powder using a robust scanning electron microscope. At close range, the powder resembles coarse gravel, a pile of similar but uneven chunks. Then he studies a second image—the same material created by colleague Hongyou Fan instead of buying from a catalog—and he observes flawlessly smooth, uniform spheres.
With regards to hydrogen fuel cells, cofacial cobalt porphyrins are considered better than platinum. Only a chemist is probably aware of such a compound. But these molecules—which are suitable for enabling a chemical reaction that’s necessary to create power from hydrogen and oxygen—could be the next huge advance in alternative energy.
Researchers have have found that bismuth has a strange characteristic that can be exploited to save the environment.
