Nanotechnology for clean drinking water
One way of removing harmful nitrate from drinking water is to catalyse its conversion to nitrogen. This process suffers from the drawback that it often produces ammonia. By using palladium nanoparticles as a catalyst, and by carefully controlling their size, this drawback can be partially eliminated.

Read moreLiquids and glasses relax, too. But not like you thought.
A new insight into the fundamental mechanics of the movement of molecules offers a surprising view of what happens when you pour a liquid out of a cup. More important, it provides a theoretical foundation for a molecular-level process that must be controlled to ensure the stability of important protein-based drugs at room temperature.

Read moreNew technique enables nanoscale-resolution microscopy of large biological specimens
Instead of making their microscopes more powerful, researchers have discovered a method that enlarges tissue samples by embedding them in a polymer that swells when water is added. This allows specimens to be physically magnified, and then imaged at a much higher resolution.

If in the future electrodes are inserted into the human brain - either for research purposes or to treat diseases - it may be appropriate to give them a 'coat' of nanowires that could make them less irritating for the brain tissue. However, the nanowires must not exceed a certain length, according to new research.
