Solar to Chemical Energy Conversion with Photocatalytic Heterostructures made of Earth Abundant Materials

Cu2ZnSnS4 (CZTS) is one of the most promising materials for solar energy harvesting. Made of highly abundant, widely distributed and relatively biocompatible elements, and with a direct band gap of 1.5 eV, CZTS is an affordable, greener and more sustainable alternative to other semiconductors such as GaAs, CdTe, CuInS2 (CIS), or CuInxGa1-xSe2 (CIGS).

Gschneidner participates in MRS videoconference

Karl Gschneidner Jr., Ames Laboratory's own "Mr. Rare Earths," did an interactive teleconference with materials science and engineering students at the MRS Fall conference on Dec. 2, 2013. Gschneidner participated in the “Exploration of the Impact of Materials on Society” event, which included a short talk on rare earths and their importance to society, an educational activity, and a question and answer session.

Teleconferencing goes 3-D

Nik Karpinsky and Song Zhang have developed 3-D teleconferencing technology that's live, real-time and streaming at 30 frames per second. They say it took a lot of late nights to solve the technical problems associated with image capture, transmission and display. They also say the technology could be ready for smart phones in a few years. Image

Restoration Sites

During the 1940s, Iowa State University and the Ames Laboratory conducted scientific research in support of the nation’s historic Manhattan Project, contributing to the effort to purify uranium for the first self-sustaining chain reaction at the University of Chicago. This effort, as well as scientific research at the Ames Laboratory in the 1950s, resulted in several sites around Ames becoming contaminated by radioactive and hazardous wastes.
