Microscopically tiny ferromagnetic platelets exhibit a phenomenon which could be exploited in the future for particularly stable magnetic data storage: so-called magnetic vortex cores. Five years ago, researchers at the Max Planck Institute for Intelligent Systems found a way to reverse the magnetic field needles despite their stability using only a tiny amount of energy so that their tips pointed in the opposite direction. Such a switching process is necessary to enable the vortex cores to be used in data processing. The Stuttgart scientists have now discovered a new mechanism which makes this switching process at least 20 times faster and confines it to a far smaller region than before.

Elektronenmikroskope nutzen einen fokussierten Elektronenstrahl, um winzige Objekte sichtbar zu machen. Wird das Instrument mit einem Gasinjektionssystem kombiniert, lassen sich Materialproben manipulieren und nanometerfeine Oberflaechenstrukturen darauf "schreiben". Empa-Forschende haben mit Wissenschaftlern der EPFL diese Methode nun genutzt, um Laser zu verbessern.

Solar cells made from organic materials are inexpensive, lightweight and flexible, but their performance lags behind cells that contain silicon or other inorganic materials. Cornell chemist William Dichtel and colleagues have found a way to synthesize ordered organic films that could be a major step toward solving this problem.

As cells assemble into a doughnut shape and ascend a hydrogel cone, they do work and thereby reveal the total power involved in forming a three-dimensional structure. That measure not only could help tissue engineers understand their living building materials better, but could also add insight to the understanding of natural tissue formation.

A new discovery promises to help physicians identify patients most likely to benefit from breast cancer drug therapies. If the compound, called "Nanobody", proves effective in clinical trials, it would represent a significant advance for breast cancer drug therapy because some drugs are effective only in some people.

In a development that holds intriguing possibilities for the future of industrial catalysis, as well as for such promising clean green energy technologies as artificial photosynthesis, researchers with the Lawrence Berkeley National Laboratory (Berkeley Lab) have created bilayered nanocrystals of ametal-metal oxide that are the first to feature multiple catalytic sites on nanocrystal interfaces. These multiple catalytic sites allow for multiple, sequential catalytic reactions to be carried out selectively and in tandem.
