We are really delighted to welcome Assistant Professor of Chemistry Ashok Ajoy to the College of Chemistry. Ashok most recently held a postdoctoral appointment in the lab of Alex...

The sheer number of C–H bonds in the precursor to the antibiotic erythromycin shows just how tricky a task it is to target a single one. The oxidation of a single C–H bond (red) makes erythromycin six times more biologically active than its precursor 6-deoxy erythromycin A – this chemical feat...

Scanning tunneling microscope image of wide-band metallic graphene nanoribbon (GNR). Each cluster of protrusions corresponds to a singly-occupied electron orbital. The formation of a pentagonal ring near each cluster leads to a more than tenfold increase in the conductivity of metallic GNRs. The GNR backbone has a width of 1.6...

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.
