A step closer to commercialization for a new green solvent
The Circa Group (Melbourne, Australia; www.circagroup.com.au) and the Green Chemistry Center of Excellence at the University of York (U.K.; www.york.ac.uk) have signed an agreement to develop and commercialize a novel “green” solvent called Cyrene. Cyrene is a polar aprotic solvent…
Bioengineers make an ‘ideal’ hydrogel for antimicrobial applications
Although several antimicrobial hydrogels have been developed in recent years, they all have one or more drawbacks, such as possible toxicity, insufficient stability and biodegradability, and high costs. These and other drawbacks have been overcome with a synthetic hydrogel being…
