Highly resorptive metal-organic frameworks

Gases and pollutants can be filtered from air and liquids by means of porous, crystalline materials, such as metal–organic frameworks (MOFs). To further partition these pores and enhance their sorption capacity, a team ...

Photonic gels are colorful sensors

(Phys.org)—Materials scientists at Rice University and the Massachusetts Institute of Technology (MIT) have created very thin color-changing films that may serve as part of inexpensive sensors for food spoilage or security, ...

Rare-earth half-sandwiches prove rewarding

The chemical frameworks of ’natural products’—molecules generated by biological organisms—have inspired many of today’s most potent pharmaceuticals. But the complexity of these compounds makes time-consuming ...

Heavy Pyridine Crystallizes Differently

(PhysOrg.com) -- The nuclei of ordinary hydrogen atoms contain only a single proton. If a neutron is added, the hydrogen becomes deuterium. In principle, molecules that contain deuterium in place of hydrogen atoms are chemically ...
