Imaging the smallest atoms provides insights into an enzyme's unusual biochemistry      (via sciencedaily.com) 

A team has used neutron crystallography to image all of the atoms in a radical intermediate of a copper amine oxidase enzyme. They disclosed previously unknown details, such as precise conformational changes, that help to explain the enzyme's biochemistry. This work might help researchers engineer enzymes that facilitate unusual chemistry or are highly efficient at room temperature that are useful in chemical industry.

Fast-track strain engineering for speedy biomanufacturing      (via sciencedaily.com) 

Using engineered microbes as microscopic factories has given the world steady sources of life-saving drugs, revolutionized the food industry, and allowed us to make sustainable versions of valuable chemicals previously made from petroleum. But behind each biomanufactured product on the market today is the investment of years of work and many millions of dollars in research and development funding. Scientists want to help the burgeoning industry reach new heights by accelerating and streamlining the process of engineering microbes to produce important compounds with commercial-ready efficiency.

New recipes for origin of life may point way to distant, inhabited planets      (via sciencedaily.com)     Original source 

Life on a faraway planet -- if it's out there -- might not look anything like life on Earth. But there are only so many chemical ingredients in the universe's pantry, and only so many ways to mix them. Scientists have now exploited those limitations to write a cookbook of hundreds of chemical recipes with the potential to give rise to life. Their ingredient list could focus the search for life elsewhere in the universe by pointing out the most likely conditions -- planetary versions of mixing techniques, oven temperatures and baking times -- for the recipes to come together.

Researchers offer insights into solid-electrolyte interphases in next-gen aqueous potassium-ion batteries      (via sciencedaily.com) 

Aqueous potassium-ion batteries are a promising alternative to lithium-ion batteries owing to their safety and low cost. However, not much is known about the properties of the solid-electrolyte interphases (SEI) that form between the electrode and the aqueous electrolyte. To address this knowledge gap, researchers from Japan have now conducted a study using advanced scanning electrochemical microscopy and operando electrochemical mass spectrometry. Their findings provide a deeper understanding of SEI in next-generation batteries.

Scientists invent a bright way to upcycle plastics into liquids that can store hydrogen energy      (via sciencedaily.com) 

Scientists have created a process that can upcycle most plastics into chemicals useful for energy storage, using light-emitting diodes (LEDs) and a commercially available catalyst, all at room temperature. The new process is very energy-efficient and can be easily powered by renewable energy in the future, unlike other heat-driven recycling processes like pyrolysis. Currently, only nine per cent of plastics globally are recycled and the rest are typically discarded in landfills or incinerated.

Extending the playing field for organosulfurs: a new way to synthesize sulfinate esters      (via sciencedaily.com) 

Sulfinate esters, a type of organosulfur compounds, are typically synthesized using thiols. However, these substances are difficult to work with due to their unpleasant smell and oxidizability in air. Now, a research team has found a way to produce sulfinate esters through the direct oxidation of thioesters, which are easily accessible and stable. Their findings will help expand the field of organosulfur chemistry and hopefully lead to new applications in pharmaceuticals.

Efficient and mild: Recycling of used lithium-ion batteries      (via sciencedaily.com) 

Lithium-ion batteries (LIBs) provide our portable devices like tablets and mobiles -- and increasingly also vehicles -- with power. As the share of volatile renewable energy needing electricity storage increases, more and more LIBs are needed, lithium prices rise, resources dwindle, and the amount of depleted batteries that contain toxic substances increases. Researchers introduce a novel approach for the recovery of lithium from used LIBs.
