battery storage

The urgent threat of climate change, driven by the burning of carbon fuels, requires bold and drastic action on a global scale. Communities in high-risk areas that are increasingly subject to natural disasters, such as recent wildfires in California and flooding in Texas, must adapt and relocate. Food supply chains are struggling as increased drought or volatile weather...

women trailblazers

Guided by CRISPR pioneer Jennifer Doudna, a formidable entrepreneur in her own right, C&EN profiled 15 women working in the Chemical industry in academics and startups in C&EN's 2020 Trailblazers. Four of them are affiliated with UC Berkeley's College of Chemistry. They have collectively launched more than 30 start-ups aimed at developing treatments for rare diseases, building better batteries, and more. They’re chemical scientists at the top of their game. They’re role models building and mentoring teams. And yes, they’re badasses. They live by the motto “Nobody ever got anywhere by listening to no.”

SkyDeck features College startups

UC Berkeley is not just one of the best research universities in the world, but also a unique place for entrepreneurs, students and alumni to grow and build their own innovative startups. Many of the ideas are based on issues young entrepreneurs first encountered in Berkeley classes or labs. Two College of Chemistry startups presented among 23 young companies last week at Berkeley SkyDeck’s annual Demo Day, where entrepreneurs pitched new devices, apps or inventions that, they hope, will provide big, bold fixes to the world’s problems, from climate change to disease.
