Photochemical deracemization of chiral compounds achieved

Enantiomeric molecules resemble each other like right and left hands. Both variants normally arise in chemical reactions. But frequently, only one of the two forms is effective in biology and medicine. Completely converting ...

Researchers visualize novel catalyst at work

A novel catalysis scheme enables chemical reactions that were previously virtually impossible. A method developed at the University of Bonn is also environmentally friendly and does not require rare and precious metals.

Team identifies water-bearing minerals on asteroid Bennu

A Southwest Research Institute-led team discovered evidence of abundant water-bearing minerals on the surface of the near-Earth asteroid (101955) Bennu. Using early spectral data from NASA's OSIRIS-REx spacecraft orbiting ...

Groundwater Cleanup at Superfund Site

(PhysOrg.com) -- A chain of chemical reactions between organic waste and naturally occurring chromium appears to explain the long-standing elevated levels of the chemical chromium-6, a human carcinogen, in groundwater at ...

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 ...

The serendipitous discovery of a new green chemistry method

Dr. Petri Turhanen was working on a synthesis of a modified version of the biological molecule adenosine triphosphate (ATP), when he discovered that the cation exchange resin he was using was unintentionally producing another ...
