"IBN researchers have successfully achieved simultaneous control of the phase purity and nanostructure of Li2MnSiO4 for the first time," said Professor Jackie Y. Ying, IBN Executive Director. "This novel synthetic approach would allow us to move closer to attaining the ultrahigh theoretical capacity of silicate-based cathodes for battery applications."

This cryo-electron tomography image reveals the internal structure of an ultra-small bacteria cell like never before. The cell has a very dense interior compartment and a complex cell wall. The darker spots at each end of the cell are most likely ribosomes. The image was obtained from a 3-D reconstruction. The scale bar is 100 nanometers.

The newfound young star clusters lie thousands of light-years below the plane of our Milky Way galaxy, a flat spiral disk seen in this artist's conception. If alien lifeforms were to develop on planets orbiting these stars, they would have views of a portion, or all, of the galactic disk.

A Defense Advanced Research Projects Agency image represents DARPA’s High-Assurance Cyber Military Systems program, which seeks to create technology for constructing systems that are functionally correct and satisfy safety and security properties.

Chemists from Boston College and UMass Amherst applied two nano-scale coatings to a unique form of carbon, known as 3DOm. The resulting boost in 3DOm's stability produced performance gains that could lead to the material's use in lithium-air batteries.

Initially the substrate is prepared by depositing Au nanoparticles on it and covering it with a hole-patterned oxide. The first nanowires grow from these holes and after the oxide is removed, the other type of nanowires are grown via the deposited nanoparticles. The resulting dual-type array is presented on the electron micrograph on the right.

The scanning electron microscopies (SEM) show how regularly the funnels etched in a silicon substrate are arranged (left: the line segment = 5 microns; right: 1 micron). The funnels measure about 800 nanometers in diameter above and run down to about a hundred nanometers at the tip.

This illustration depicts a short row of vortices held in place between the edges of a nanowire developed by Johns Hopkins scientists.

Both projects ideally fit into the internationalization concept of KIT. Among others, this concept focuses on the establishment of international innovation networks, the internationalization of higher education, and the setup of joint infrastructures abroad. Cooperation with institutions in Asia and in particular in China is of major interest to KIT due to the rapid development of science and research in that country and its high economic power. So far, KIT has pursued some 100 cooperative ventures with more than 40 institutions in China.
