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.

Collaborative initiative highlights successes and challenges in global bioethics training

A new Penn Nursing initiative explores the impact of federally funded international bioethics training programs. The collaborative initiative, published in the Journal of Empirical Research on Human Research Ethics, highlights both the significant achievements and ongoing challenges in building bioethics research capacity in low- and middle-income countries.
