The EPA is being urged to regulate a group of chemicals that are contaminating the public water supply in dozens of states. The group of chemicals known as PFAS were used in everything from nonstick cookware to firefighting foam. (Aug. 13)
|Chemicals that keep drinking water flowing may also cause fouling|

Many city drinking water systems add softening agents to keep plumbing free of pipe-clogging mineral buildup. According to new research, these additives may amplify the risk of pathogen release into drinking water by weakening the grip that bacteria -- like those responsible for Legionnaires' disease -- have on pipe interiors.
|Artificial enzymes perform reactions on living cells|

Nature has evolved thousands of enzymes to facilitate the many chemical reactions that take place inside organisms to sustain life. Now, researchers have designed artificial enzymes that sit on the surfaces of living cells and drive reactions that could someday target drug therapies to specific organs.
|Liquid microscopy technique reveals new problem with lithium-oxygen batteries|

Using an advanced, new microscopy technique that can visualize chemical reactions occurring in liquid environments, researchers have discovered a new reason lithium-oxygen batteries -- which promise up to five times more energy than the lithium-ion batteries that power electric vehicles and cell phones -- tend to slow down and die after just a few charge/discharge cycles.
|Rethinking ketchup packets: New approach to slippery packaging aims to cut food waste|

New research aims to cut down on waste -- and consumer frustration -- with a novel approach to creating super slippery industrial packaging. The study establishes a method for wicking chemically compatible vegetable oils into the surfaces of common extruded plastics, like those used for ketchup packets and other condiments.

The biggest variety of radish on the planet may harbor chemicals that can reduce the risk of cardiovascular disease. A new study investigates.
|Hybrid catalyst with high enantiomer selectivity|

Researchers have developed a technology to create a hybrid catalyst from simple-structured, commercially available rhodium and organic catalysts, which reduces chemical waste and produces molecules with high selectivity of an enantiomer, a pair of molecular structures that are non-superimposable mirror images of each other. This technology is expected to assist in rapid and low-cost drug synthesis.
|Designer polymers on demand|

When jewelers create a necklace, they control the order and number of each bead or jewel they use to form a desired pattern. It's been challenging for scientists to do the same thing when designing polymers -- until now. Researchers report a new method using light and chemical reactions to control how subunits come together to form polymers with precise properties.
|A periodic table of molecular knots|

Using computational predictive models, the scientists identified a shortlist, a kind of 'periodic table', of the most designable knot types, i.e. those knots that could easily self-assemble under appropriate physical and chemical conditions. This study, and the increasingly predictive capability of molecular modelling techniques, can create novel possible perspectives for future advanced applications, like the construction of sophisticated molecular machines for loading and delivering a nanocargo.
