Atmospheric aerosols, consisting of suspended small solid and liquid particles, influence both climate and air quality. Sub-micrometre-sized particles efficiently scatter visible radiation and can act ...

An in-service lubricant encounters heat, air, corrosive agents, pressure, and other factors that cause chemical changes in the oil. Changes in oil chemistry can also impact the lubricant’s ability to ...

For more than two centuries, fossil fuels have dominated global energy and chemical production, accounting for over 80% of ...

Researchers can make the oxidation reactions used in the synthesis of organic molecules cleaner by hitching photovoltaics to electrochemistry. The idea is simple and yet it has huge implications. To ...

Microbiologists discover bacteria that eliminate toxic sulfide and use iron minerals to grow. An international group of ...

A reaction that puzzled scientists for 50 years has now been explained by researchers at Ume University. Rapid structural snapshots captured how graphite transforms into graphite oxide during ...

As the most reactive member of nature’s standard stable of amino acids, cysteine is commonly tapped as a nucleophile in enzyme active sites. But cysteine’s reactivity also makes it uniquely ...

A longstanding mystery of the periodic table involves a group of unique elements called lanthanides. Also known as rare earth elements, or REEs, these silvery-white metals are challenging to isolate, ...

A new gold-perovskite catalyst achieves record-high acetaldehyde yields from bioethanol at lower temperatures. Acetaldehyde plays an important role as a chemical building block and is commonly ...

Air, pressure, heat, corrosive agents, and other factors encountered by a lubricant during use can cause chemical changes in the oil. Changes in the oil chemistry can have a negative impact on the ...
