Optical indicators based on cholesteric liquid crystal polymers

Optical indicators based colored polymers are autonomous responsive labels that provide an optical signal to represent a specific exposure over time. Polymers that possess a high degree of order can establish structural color, ...

Nanoparticle 'backpacks' restore damaged stem cells

Within a newborn's umbilical cord lie potentially life-saving stem cells that can be used to fight diseases like lymphoma and leukemia. That is why many new parents elect to store ("bank") their infant's stem cell-rich umbilical ...

Improved method to make branched polymers

Branched polymers, polymers that look like tiny tree branches, have significant potential for water filtration, the biomedical field, nanoelectronics, and other applications. Researchers have now come up with a better way ...

Upcycling polyester could reduce plastic waste

Less than 10% of the 380 million metrics tons of annually produced plastics are currently recycled in the U.S., creating a global environmental threat caused by plastic production and the absorption of millions of tons of ...

New method to solve the plastics sustainability problem

Plastics sustainability has come a long way in recent years thanks in large part to scientific advances. But even as plastics become more and more environmentally friendly, the world continues to be polluted as many industries ...
