UC Berkeley researchers have designed an extreme-weather proven, hand-held device that can extract and convert water molecules from the air into drinkable water using only ambient sunlight as its energy source, a...

Startup to Sale: How alumnus Tom McDonald co-founded and built Mosaic Materials

May 13, 2022

Tom McDonald, chemistry Ph.D. alum 2015

Baker Hughes has acquired the startup Mosaic Materials and plans to deploy its carbon dioxide capture technology across the industrial value chain.

Tom McDonald (Ph.D. '15, Chem) was going to be a professor. That was the plan. He even had a postdoc lined up at Imperial College London and...

Ron Cohen talks about the Beacon project

August 26, 2020

In a new video from Ron Cohen, UC Berkeley Professor of Chemistry and Earth and Planetary Sciences, the remarkable change in our atmosphere with the onset of the COVID-19 pandemic is explored. Cohen postulates what the world would be like with fewer CO2 emissions.

The sky is orange because longer wavelength light (reds and oranges) are able to push through smoke particulates, whereas shorter...

Richmond Brings Air Pollution Control To The People

October 23, 2019

Ron Cohen

We hear a lot about bad air quality in California. And, it’s hard to know what to do about it. But thanks to a 2017 law, two Bay Area communities known for their air pollution are helping set their own air quality policies. But what does putting air pollution in the hands of the people really look like? In this Cross Currents report from KALW, reporter Brett Simpson attends an important community air quality meeting in Richmond as a committee of residents decide how much monitoring they should do before putting stricter standards in place. Richmond, California has some of the worst air pollution in the country. The committee was divided between more monitoring and wanting to enact stricter standards now.

Scientists use DNA origami to alter gene expression in plants

DNA origami could change the way we alter plants

new research reported from the lab of Markita Landry, a professor of chemical and biomolecular engineering at UC Berkeley, a team of scientists has taken an original approach of using DNA origami nanotechnology to slip through plant cell walls and graft small interfering RNA (siRNA) directly onto plant cells. Their research shows it is possible to directly silence genes in plants without damaging plant tissues, and without making any alterations to the plant’s genome.

MOF water harvesting technology one of ten innovations that could change the world

April 4, 2019

Testing the water harvester

The International Union of Pure and Applied Chemistry (IUPAC) has released the results of its first search for the Top Ten Emerging Technologies in Chemistry. Initiated as a special activity in honor of IUPAC’s 100th anniversary this year, the results have been published in the 2019 April-June 2019 issue of Chemistry International. Research from the lab of Omar Yaghi on water harvesting from desert air technology has been featured as one of the top 10.

Scientists discover hydration is key to improving catalyst performance for industrial use

April 4, 2019

NanoEP experiment

Scientists have used neutron scattering to identify the secret to a metal-organic framework's (MOF) ability to efficiently convert chemicals, through a process called catalysis, into new substances. By probing a material known as MOF-808-SO4, the team discovered molecular behavior that causes the catalyst to become less acidic, which could slow down the catalytic process vital in making products such as plastics, fragrances, cosmetics, flame retardants and solvents.
