Mimicking biological enzymes may be key to hydrogen fuel production      (via sciencedaily.com) 

An ancient biological enzyme known as nickel-iron hydrogenase may play a key role in producing hydrogen for a renewables-based energy economy, researchers said. Careful study of the enzyme has led chemists to design a synthetic molecule that mimics the hydrogen gas-producing chemical reaction performed by the enzyme.

Most of world's salt marshes likely to be underwater by 2100, study concludes      (via sciencedaily.com) 

Salt marshes are some of the most biologically productive ecosystems on Earth. They play an outsized role in nitrogen cycling, act as carbon sinks, protect coastal development from storm surge, and provide critical habitats and nurseries for many fish, shellfish, and coastal birds. According to new research, more than 90 percent of the world's salt marshes are likely to be underwater by the end of the century. These findings come from a 50-year study of ecosystem changes in Great Sippewissett Marsh in Falmouth, Mass.

The Greenland Ice Sheet is close to a melting point of no return      (via sciencedaily.com) 

A new study using simulations identified two tipping points for the Greenland Ice Sheet: releasing 1000 gigatons of carbon into the atmosphere will cause the southern portion of the ice sheet to melt; about 2500 gigatons of carbon means permanent loss of nearly the entire ice sheet. Having emitted about 500 gigatons of carbon, we're about halfway to the first tipping point.

Closed loop for circular economy: New polymer recycling strategy ensures both high stability and complete recyclability      (via sciencedaily.com) 

Large amounts of plastic waste are incinerated or deposited in landfills. This degrades the environment and depletes valuable resources. In this light, recycling plastics such as polymers is promising. However, recycling diminishes their quality. Recently, researchers have proposed a 'closed-loop' recycling process based on polymer microparticles. It produces fully recyclable polymer films with high mechanical stability and fracture energy, which they retain upon recycling.

The devil is in the details: Re-imagining fertilizer precursor synthesis      (via sciencedaily.com) 

Researchers have improved the Faradaic efficiency of the nitrogen reduction reaction into ammonia by straightforward optimization of chemical process parameters. They found that trace water was the probable source of the high selectivity by facilitating incorporation of lithium oxide into the solid electrolyte interphase. These findings will also aid optimization of other analogous reactions, and thus help the chemicals industry optimize the sustainability of one of the most carbon-intensive reactions globally.
