Experiment improves predictions of uranium dispersion

The predictive models that describe the fate and transport of radioactive materials in the atmosphere following a nuclear incident (explosion or reactor accident) assume that uranium-bearing particulates would attain chemical ...

Carbon nanostructures grow under extreme particle bombardment

(Phys.org) —Nanostructures, such as graphene and carbon nanotubes, can develop under far extremer plasma conditions than was previously thought. Plasmas (hot, charged gases) are already widely used to produce interesting ...

Slow road to stability for emulsions

By studying the behavior of tiny particles at an interface between oil and water, researchers at Harvard have discovered that stabilized emulsions may take longer to reach equilibrium than previously thought.

The atmosphere of an exoplanet reveals secrets about its surface

As astronomers have begun to gather data on the atmospheres of planets, we're learning about their compositions and evolution. Thick atmospheres are the easiest to study, but these same thick atmospheres can hide the surface ...

The bubbly chemistry behind carbonated beverages

Many people love the refreshing effervescence of a soda, champagne, beer or sparkling water. When you take a sip, the gas bubbles in the beverage burst, and the released gas tickles your nose. But have you ever wondered how ...
