Path to net-zero carbon capture and storage may lead to ocean      (via sciencedaily.com) 

Engineering researchers have developed a novel way to capture carbon dioxide from the air and store it in the 'infinite sink' of the ocean. The approach uses an innovative copper-containing polymeric filter and essentially converts CO2 into sodium bicarbonate (aka baking soda) that can be released harmlessly into the ocean. This new hybrid material, or filter, is called DeCarbonHIX (i.e., decarbonization through hybrid ion exchange material). The research has demonstrated a 300 percent increase in the amount of carbon captured compared with existing direct air capture methods.

Chemists design new molecule, with oxygen as the star of the show      (via sciencedaily.com) 

Chemists have achieved a new feat in the realm of chemical design and synthesis: They've helped create the first example of a synthetic molecule, with an asymmetric oxygen atom as its centerpiece, that remains stable and nonreactive -- despite this type of molecule's tendency in nature to be touchy and short-lived. What makes this feat unique is that the new molecule is chiral, which means it has a non-superimposable mirror image.
