Engineers find antioxidants improve nanoscale visualization of polymers — ScienceDaily

Reactive molecules, such as free radicals, can be produced in the body after exposure to certain environments or substances and go on to cause cell damage. Antioxidants can minimize this damage by interacting with the radicals before they affect cells. Led by Enrique Gomez, professor of chemical engineering and materials science and engineering, Penn State […]

Controlling the nanoscale structure of membranes is key for clean water, researchers find

UNIVERSITY PARK, Pa. — A desalination membrane acts as a filter for salty water: push the water through the membrane, get clean water suitable for agriculture, energy production and even drinking. The process seems simple enough, but it contains complex intricacies that have baffled scientists for decades — until now. Researchers from Penn State, The […]

Germanium telluride’s hidden properties at the nanoscale revealed — ScienceDaily

Germanium telluride (GeTe) is known as a ferrolectric Rashba semiconductor with a number of interesting properties. The crystals consist of nanodomains, whose ferrolectric polarization can be switched by external electric fields. Because of the so-called Rashba effect, this ferroelectricity can also be used to switch electron spins within each domain. Germanium telluride is therefore an […]
