Commercial Opportunities: The use of these carbon coated metal oxide nanoparticles enables the realization of environmentally friendly, cost-effective, and lightweight electrochemical energy storage devices for future large scale applications.
Transition metal oxides provide higher specific capacities compared to graphite, which is the actual state-of–the-art in Li-ion batteries. Nevertheless, the main drawback of these conversion materials so far has been a reduced cycling stability and limited obtainable specific capacities at elevated applied current densities.
However, these drawbacks could be overcome by utilizing the new carbon coated metal oxide nanoparticles. As a matter of fact, by using these materials it is possible to realize batteries offering a superior electrochemical performance at high current densities and advanced cycle life. Moreover, such enhanced electrodes are easily recyclable and 100% environmentally friendly.

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
