Nov. 30, 2022 —Researchers have discovered a way to chemically recycle PVC into usable material, finding a way to use the phthalates in the plasticizers -- one of PVC's most noxious components -- as the ...
May 12, 2021 —The acidity of the atmosphere is increasingly determined by carbon dioxide and organic acids such as formic acid. The second of these impact the growth of clouds and pH of rainwater. But the chemical ...
2021年7月1日-Zeolites are extremely porous materials: Ten grams can have an internal surface area the size of a soccer field. Their cavities make them useful in catalyzing chemical reactions and thus saving ...
Sep. 8, 2021 —Protons in aqueous solution can usually migrate very quickly -- much faster compared to other ions. However, this only applies when they are in a space greater than two nanometers, as a new study ...
May 25, 2022 —A team of microbiologists has succeeded in using bacteria for the controlled storage and release of hydrogen. This is an important step in the search for carbon-neutral energy sources in the interest ...
Sep. 9, 2021 —Research has the potential to speed up development of high-capacity storage batteries while spending less time in a ...
Jan. 22, 2021 —Degradable, bio-based polymers offer options for chemical recycling, and they can be a tool to store and release useful molecules. Scientists have developed a class of sugar-based polymers that are ...
May 11, 2022 —The go-to materials for building home furniture, décor and floors are composite wood products that come in large sheets. But the glues and resins holding together particleboard, fiberboard and ...
June 22, 2021 —The way in which a compound inspired by nature produces hydrogen has now been described in detail. These findings are the foundation for the energy-efficient production of hydrogen as a sustainable ...
Oct. 19, 2022 —Hydrogen gas could someday replace fossil fuels as a 'clean' energy source, producing only water and energy. However, handling large quantities of gaseous hydrogen is cumbersome, and ...
