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.

Unraveling the Mysteries of Carbonic Acid

Chemical scientist Rich Saykally led a study that revealed how gaseous carbon dioxide molecules dissolve in water to initiate the chemistry that yields carbonic acid and bicarbonate. Though carbonic acid exists for only a tiny fraction of a second, it imparts a lasting impact on Earth’s atmosphere and geology, as well as on the human body. More>

Leaving on a Biofueled Jet Plane

Berkeley Lab’s Alex Bell, Corinne Scown and Dean Toste have developed a catalytic process for converting sugarcane biomass into a new class of aviation fuel and lubricant base oils that could help biorefineries achieve net life-cycle greenhouse gas savings of up to 80-percent. The work was conducted at the Energy Biosciences Institute. More>
