Ultrafiltration without pressure - the power of gravity
Ultrafiltration is one of the techniques currently used for disinfecting water - viruses and bacteria are reliably retained by a membrane with extremely small pores. For more than ten years, Eawag has successfully been carrying out research to determine how this method can function using the effect of gravity on water instead of high pressure, cleaning and chemicals.

Worms in high-tech housing replace laboratory mice
In an effort to improve drug, cosmetic and other chemical product tests, Nagi Bioscience has created a device that automatically grows, feeds, houses and analyzes laboratory worms. This invention will save researchers both time and money and sharply reduce the number of tests that require laboratory rondents.

One step further towards cheap aluminium
The energy transition depends on technologies that allow the inexpensive temporary storage of electricity from renewable sources. A promising new candidate is aluminium batteries, which are made from cheap and abundant raw materials. Scientists from Maksym Kovalenko's research group, which is based at both ETH Zurich and in Empa's Laboratory for Thin Films and Photovoltaics , are researching and developing batteries made from abundant raw materials.

Traces in scrap
Last year Empa's inorganic analytics lab was granted the status of "Reference Laboratory" within the scope of the ProSUM project, funded by the EU. Fine-grained samples of shredder waste from scrapped cars, e-waste or mine dumps from all over Europe end up here. Empa chemists find out what is in them, what is worth extracting and what could be dangerous for staff at recycling plants.

Studying dwarf galaxies to get the big picture
EPFL scientists have completed the fastidious task of analyzing 27 dwarf galaxies in detail, identifying the conditions under which they were formed and how they've since evolved. These small-scale galaxies are perfect for studying the mechanisms of new star formation and the very first steps in the creation of the universe.

Individual impurity atoms detectable in graphene
A team including physicists from the University of Basel has succeeded in using atomic force microscopy to clearly obtain images of individual impurity atoms in graphene ribbons. Thanks to the forces measured in the graphene's two-dimensional carbon lattice, they were able to identify boron and nitrogen for the first time, as the researchers report Advances.

New Method Speeds Up Development of Medication
One of the key steps in developing new drugs is determining the atomic structure of its biologically active substances. This generally involves performing X-ray analyses of single crystal structures to determine the ingredient's detailed three-dimensional set-up. However, growing suitable single crystals is often a complex and time-consuming process.

Cleaner diesel emissions
More effective control of diesel nitrogen oxides through dosed addition of ammonia In diesel engines, the burning of the fuel releases nitrogen oxides (NOx), which are harmful to human health. The automobile industry therefore developed a technique that reduces these emissions: Gaseous ammonia is added to the exhaust and, prompted by a catalyst, reacts with the nitrogen oxides to produce harmless nitrogen and water.

Strom on demand
If photovoltaic or wind power plants produce more electricity than the network can absorb, valuable energy is lost. At the ESI Platform, PSI researchers are investigating how fuel cells can contribute to making this energy usable in a targeted way through storage. The power network cannot store energy.

Imaging at Paul Scherrer Intitute helps to increase production at ABB site in Aaargau
The ABB facility in Wettingen, Aargau, got practical recommendations on increasing output in the manufacture of ceramic components. The ceramics in question are voltage-dependent resistors used in overvoltage protectors - a kind of lightning protection system - for example, in electrical transmission lines.

The first precise measurement of a single molecule’s effective charge
For the first time, scientists have precisely measured the effective electrical charge of a single molecule in solution. This fundamental insight of an SNSF Professor could also pave the way for future medical diagnostics. Electrical charge is one of the key properties that allows molecules to interact.
