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.

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.

Some spiders can transfer mercury contamination to land animals      (via sciencedaily.com) 

Sitting calmly in their webs, many spiders wait for prey to come to them. Arachnids along lakes and rivers eat aquatic insects, such as dragonflies. But, when these insects live in mercury-contaminated waterways, they can pass the metal along to the spiders that feed on them. Now, researchers have demonstrated how some shoreline spiders can move mercury contamination from riverbeds up the food chain to land animals.
