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.

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.

Precisely arranging nanoparticles      (via sciencedaily.com) 

In the incredibly small world of molecules, the elementary building blocks -- the atoms -- join together in a very regular pattern. In contrast, in the macroscopic world with its larger particles, there is much greater disorder when particles connect. A research team has now succeeded in achieving the same precise arrangement of atoms shown in molecules, but using nanometer-sized particles, known as 'plasmonic molecules' -- combinations of nanoscale metallic structures that have unique properties.

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.

Novel ligands for transition-metal catalysis of photoreactions      (via sciencedaily.com) 

Transition metals exchange electrons with supporting ligands to form complexes that facilitate reaction catalysis in several industries, like pharmaceutical production. Both the metal center and the ligand moiety have pivotal roles in enabling catalysis. While numerous transition metal-catalyzed photoreactions have been developed, only a few new ligands have been reported. Researchers from Chiba University have now developed novel ligands to create transition metal complexes, defining new reaction capabilities.

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.
