Read more'Electronic skin' from nanoparticles could improve early breast cancer detection
For detecting cancer, manual breast exams seem low-tech compared to other methods such as MRI. But scientists are now developing an 'electronic skin' that 'feels' and images small lumps that fingers can miss. Knowing the size and shape of a lump could allow for earlier identification of breast cancer, which could save lives.

With fears growing over chemical and biological weapons falling into the wrong hands, scientists are developing microrockets to fight back against these dangerous agents, should the need arise. In a new paper, they describe new spherical micromotors that rapidly neutralize chemical and biological agents and use water as fuel.

A multidisciplinary engineering team developed a new nanoparticle-based material for concentrating solar power plants designed to absorb and convert to heat more than 90 percent of the sunlight it captures. The new material can also withstand temperatures greater than 700 degrees Celsius and survive many years outdoors in spite of exposure to air and humidity.

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.

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.

Read moreCan the wave function of an electron be divided and trapped?
Electrons are elementary particles - indivisible, unbreakable. But new research suggests the electron's quantum state - the electron wave function - can be separated into many parts. That has some strange implications for the theory of quantum mechanics.

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.

Scientists have made the first observation of the electronic structure in silver-rhodium (Ag-Rh) alloy nanoparticles to investigate why the alloy possesses a hydrogen absorbing/storage property like palladium does, given that bulk Ag and Rh do not form an alloy, and that neither element alone is a hydrogen absorbing/storage metal.
