The global threat of salt contamination to water supplies

Research from Weitzman’s Allison Lassiter and an international team of researchers highlights how a combination of climate change impacts and localized human activities are intensifying the increase in salt in vital freshwater sources.

Beneath the surface: Diving into water’s hidden carbon-cleaning capabilities
3D rendering of water molecules on a copper surface.

Water molecules become increasingly disordered at the surface of a catalyst. Researchers found that this disordered interfacial water, shown transitioning from structured (left) to disorganized (right), plays a key role in speeding up the conversion of carbon monoxide into ethylene, a valuable fuel and chemical building block.

Beneath the surface: Diving into water’s hidden carbon-cleaning capabilities

Penn materials scientist Shoji Hall and colleagues have found that manipulating the surface of water can allow scientists to sustainably convert greenhouse gases like carbon dioxide and carbon monoxide to higher energy fuel sources like ethylene.

Strongest nor’easters getting stronger

Research from Professor Michael Mann and Ph.D. students Annabelle Horton and Mackenzie Weaver shows that as the worst of these East Coast winter storms intensify, so does their destructive potential—a facet that current coastal risk assessments often ignore.
