Princeton builds research ties with historically black universities

As an early career scientist, Max Fontus wondered how successful researchers repeatedly make discoveries worth publishing. Collaborating with a Princeton engineering professor this summer, he realized that working with scientists from other fields of research results in a cross-pollination of ideas that lays the foundation for great progress in science.

Mapping the structure of protonated water clusters

Water molecules are continuously forming short-lived networks called clusters. These can in turn bind positively charged protons, and such clusters can provide active functional groups in proteins. Using infrared spectroscopy, it is possible to determine the bond strengths, geometrical structures and chemical properties of protonated water clusters. In order to measure the spectrum of molecular vibrations in clusters it is, however, necessary to use other molecules as messengers.

Colossal magnetoelectricity points the way to ultra-dense data storage

A team of scientists at Rutgers University has found a material in which an electric field can control the overall magnetic properties of the material. If the magnetoelectric effect discovered by the Rutgers group can be extended to higher temperatures, it could be useful for manipulating small-scale magnetic bits in ultra high-density data storage.

Breakthrough discovery enables nanoscale manipulation of the piezoelectric effect

The generation of an electric field by the compression and expansion of solid materials is known as the piezoelectric effect, and it has a wide range of applications ranging from everyday items such as watches, motion sensors and precise positioning systems. Researchers have now discovered how to control this effect in nanoscale semiconductors called quantum dots, enabling the development of incredibly tiny new products.

Laserlicht aus polymeren Mikrokelchen

In einem interdisziplinaeren Projekt ist es Wissenschaftlern des KIT gelungen, eine neue Erscheinungsform von optischen Resonatoren zu schaffen: Mikrokelche. Diese Polymerstrukturen sind durch ihre Form und ihre glatte Oberflaeche besonders effiziente Quellen fuer Laserlicht. Zudem haben sie das Potenzial kleinste Bio-Molekuele, Viren oder Gefahrstoffe nachzuweisen.
