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.

Read moreTissue engineers use new system to measure biomaterials, structures
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.

Read moreCaught red-handed - Detection of latent fingerprints through release of fluorescein from a nanofiber mat
When a forensic agent dusts a surface with powder or exposes it to the vapors of an iodine chamber, mystery fans know what is going on: This is how latent fingerprints are made visible so that they can be compared to those of a suspect. Scientists have now developed a new process for especially rapid and simple detection of fingerprints. All it takes is a special nanofiber mat that is pressed onto the suspect surface and briefly treated with hot air - the fingerprints appear as red ridge patterns.
