Tiny carbon nanotube pores make big impact

Researchers have created a new kind of ion channel consisting of short carbon nanotubes, which can be inserted into synthetic bilayers and live cell membranes to form tiny pores that transport water, protons, small ions and DNA.

Nanosafety research: Are scientists on the right track?

Empa toxicologist Harald Krug has lambasted his colleagues in the journal Angewandte Chemie. He evaluated several thousand studies on the risks associated with nanoparticles and discovered no end of shortcomings: poorly prepared experiments and results that don't carry any clout. Instead of merely leveling criticism, however, Empa is also developing new standards for such experiments within an international network.

Imaging of electrons moving around at 80,000m per second in semiconductor

Researchers succeeded in direct observation and video imaging of electron flow at 80,000m per second in a semiconductor. They did so by combining a new laser pulse light source and a photoemission electron microscope (PEEM) to develop an ultra high-speed microscope that enabled visualization of electrons on a 20 nanometer and 200 femtosecond scale.

Self-assembly of layered membranes

Recently, scientists used self-assembly under controlled conditions to create a membrane consisting of layers with distinctly different structures. Now, the team utilized small-angle x-ray scattering (SAXS) to better determine these structures and study how they form. This new information paves the way for design and synthesis of hierarchical structures with biomedical applications.

A new cheap and efficient method to improve SERS

Researchers have developed a new method to overcome the problems of Surface Enhanced Raman Spectroscopy (SERS), an ultra-sensitive analytical technique able to detect chemicals in very low concentration, even up to single molecules, and also to retrieve structural information.
