Observational Constraints Reveal Biases in OVOC-Driven Radical Chemistry. Schematic illustration of how limited OVOC constraints bias simulations of radical (ROₓ) chemistry and ozone formation. When ...

The indoor environment contains multiple sources of chemical compounds. These include continuous emissions from housing materials such as furniture, floors and furnishings, but also periodic intense ...

The content details various categories of AOPs—including ozone-based, radiation-driven, catalytic, and physical methods—highlighting their mechanisms, chemicals involved, ...

Fragrances and lotions don't just change the way people smell, they actively alter the indoor air chemistry around the wearer, disrupting a critical natural process the body uses to protect itself ...

Donghyun Rim, associate professor of architectural engineering, gestures toward a test chamber to evaluate performance of low-cost air quality sensors. Rim studies the impact of human presence on ...

Methane is a powerful greenhouse gas that is second only to carbon dioxide in driving up global temperatures. But it doesn't linger in the atmosphere for long thanks to molecules called hydroxyl ...

Electronic cigarettes — or vapes — can release puffs of vapor in aromatic clouds. The health risks of breathing in this secondhand or passive vapor aren’t fully understood. So, researchers reporting ...

The ozone layer is a stratospheric region characterized by elevated concentrations of ozone (O₃), typically peaking between 15 and 35 km altitude, where photochemical equilibrium between ozone ...
