New antidote could save lives from deadly hydrogen sulfide gas Hydrogen sulfide, a colorless gas that smells like rotten eggs, is produced naturally from decaying matter. This gas is lethal to breathe in, and hydrogen sulfide present in high concentrations can cause death very rapidly.

Reshaping tradition: Experts share why commonly used measuring method for fluorescence is not always appropriate Fluorescence is a well-known phenomenon with many practical applications that has been studied for decades. Despite this, a commonly used mathematical formalism to describe how it evolves over time does not make physical sense under certain conditions, as researchers from the Institute of Physical Chemistry, Polish Academy of Sciences have recently discovered.

Predicting atomic structures proves useful in energy and sustainability Researchers at Lawrence Livermore National Laboratory (LLNL) have developed a new approach that combines generative artificial intelligence (AI) and first-principles simulations to predict three-dimensional atomic structures of highly complex materials.

Ultrafast electron imaging captures never-before-seen nuclear motions in hydrocarbon molecules excited by light The interactions between light and nitroaromatic hydrocarbon molecules have important implications for chemical processes in our atmosphere that can lead to smog and pollution. However, changes in molecular geometry due to interactions with light can be very difficult to measure because they occur at sub-Angstrom length scales and femtosecond time scales.
