By Collins Odhiambo | DatalytIQs Academy 1. The Chemistry of Daylight Every sunrise triggers a silent but powerful atmospheric reaction.In urban environments, ozone (O₃) and nitrogen dioxide (NO₂) engage in a photochemical tug-of-war — one produced as the other fades. This ratio, O₃/NO₂, is a key indicator of photochemical smog activity, helping us understand when and how the air transitions from traffic-driven pollution to sunlight-driven chemistry.

Photochemist AP De Silva on engineering molecular sensors to help revolutionise healthcare

In early October, the Centre for Origin and Prevalence of Life at ETH Zurich welcomed the new NOMIS–ETH fellows, Dr. Thomas Drant and Dr. Antonin Affholder, who presented their ongoing research projec...

Skeletal editing pushed beyond aromatic structures, sparking new opportunities in drug discovery

Photochemistry provides a pathway to swap the oxygen atom in oxetane rings with nitrogen, carbon or sulfur at a single stroke. The resulting structures, such
