Evidence stacks up for poisonous books containing toxic dyes      (via sciencedaily.com)     Original source 

Some of the attractive hues of brightly colored, cloth-bound books from the Victorian era come from dyes that could pose a health risk to readers, collectors or librarians. The latest research on these 'poison books' used three techniques -- including one that hasn't previously been applied to books -- to assess dangerous dyes in a university collection and found some volumes had levels that might be unsafe.

Exploring the structures of xenon-containing crystallites      (via sciencedaily.com)     Original source 

Noble gases have a reputation for being unreactive, inert elements, but more than 60 years ago Neil Bartlett demonstrated the first way to bond xenon. He created XePtF6, an orange-yellow solid. Because it's difficult to grow sufficiently large crystals that contain noble gases, some of their structures -- and therefore functions -- remain elusive. Now, researchers have successfully examined tiny crystallites of noble gas compounds. They report structures of multiple xenon compounds.

Scientists achieve more than 98% efficiency removing nanoplastics from water      (via sciencedaily.com)     Original source 

Linked to cardiovascular and respiratory diseases in people, nanoplastics continue to build up, largely unnoticed, in the world's bodies of water. The challenge remains to develop a cost-effective solution to get rid of nanoplastics while leaving clean water behind. That's where Mizzou comes in. Recently, researchers created a new liquid-based solution that eliminates more than 98% of these microscopic plastic particles from water.

Halogen bonding for selective electrochemical separation, path to sustainable chemical processing demonstrated      (via sciencedaily.com)     Original source 

A team has reported the first demonstration of selective electrochemical separation driven by halogen bonding. This was achieved by engineering a polymer that modulates the charge density on a halogen atom when electricity is applied. The polymer then attracts only certain targets -- such as halides, oxyanions, and even organic molecules -- from organic solutions, a feature that has important implications for pharmaceuticals and chemical synthesis processes.
