Resolving tension on the surface of polymer mixes

Better than playing with Legos, throwing polymer chains of different lengths into a mix can yield surprising results. In a new study published in EPJ E, physicists focus on how a mixture of chemically identical chains into ...

Electrically heated textiles now possible

Commuters, skiers, crossing guards and others who endure frozen fingers in cold weather may look forward to future relief as manufacturers are poised to take advantage of a new technique for creating electrically heated cloth ...

Precisely defined polymer chains now a reality

Manufactured polymers are ubiquitous in the market. These large molecules are used for synthetic clothing, rubbers and glues, and anything made of plastic. However, the material properties exhibited by man-made polymers rely ...

Naked molecules dancing in liquid become visible

Capturing the movement of molecules is not an easy task. Scientists at the Center for Soft and Living Matter, within the Institute for Basic Science (IBS) were able to observe the movement of molecules stored inside a graphene ...

Fluorescent polymer detects traces of explosive devices

Bomb plots could be thwarted with the help of a portable system for detecting traces of high explosives using fluorescent polymer nanoparticles, developed by A*STAR. Coated on to paper, these polymers display an explosive-detection ...

Novel antimicrobial polymer receives EPA approval

Nouvex, an antimicrobial additive technology clinically proven to be effective against bacteria as well as select viruses and fungi received approval from the U.S. Environmental Protection Agency, Office of Pesticide Programs, ...

Research shows how DNA molecules cross nanopores

Research presented in a new paper co-authored by Northwestern University associate professor of mechanical engineering Sandip Ghosal sheds new light on how polymers cross tiny pores ten thousand times smaller than a human ...

Systematically studying slippery surfaces

Betaines are materials with both a positively charged functional group and a negatively charged functional group linked by an alkyl chain spacer. This combination of functional groups causes betaines to strongly attract water, ...
