On the Path Toward Bionic Enzymes

Berkeley Lab chemists have successfully married chemistry and biology to create reactions never before possible. They did this by replacing the iron normally found in the muscle protein myoglobin with iridium, a noble metal not known to be used by living systems. More>

Chemical ‘Sponges’ Soak Up Toxic Cancer-fighting Drugs After Targeting Tumors

Researchers are creating materials for a cancer treatment system that can limit the side effects of chemotherapy drugs by quickly removing them from the body after use. The device can be inserted via a tiny tube into a vein, then soaks up most of these drugs like a sponge. More>

Scientists Find Surprising Link Between Rain and Airborne Particles

Rain’s reputation for cleansing the air may come with a caveat after new study findings show that they play a role in generating airborne organic particles. The findings could influence how scientists model our planet’s climate and future. The research was conducted in part by Mary Gilles of the Chemical Sciences Division. More>

Scientists Part the Clouds on How Droplets Form

A new study reveals that much more is going on at the microscopic level of cloud formation than previously thought. Scientists have determined that organic molecules effectively depressed the surface tension of the water, allowing for more efficient formation of bigger cloud droplets. This research could influence climate models. More>

Soaking Up Carbon Dioxide and Turning it into Valuable Products

Chris Chang (Chemical Sciences) and Omar Yaghi (Materials Sciences) led a study in which covalent organic frameworks were embedded with cobalt porphyrins to produce a molecular system that that not only absorbs carbon dioxide, but also selectively reduces it to carbon monoxide, a primary building block for a wide range of chemical products.

Another Milestone in Hybrid Artificial Photosynthesis

A team led by Peidong Yang, Michelle Chang and Chris Chang has combined semiconducting nanowires with select microbes to create an artificial photosynthesis system that produces renewable molecular hydrogen and uses it to synthesize carbon dioxide into methane, the primary constituent of natural gas.
