- Laser-optic measuring techniques to optimize diesel cat
The scandal surrounding VW has thrust nitric oxide (NOx) emissions from diesel vehicles into the limelight. Owing to the different engine technologies, these have always been higher than in gasolin... - A more realistic risk assessment of nanomaterials in the environment
A wide range of industrially synthesized nanomaterials are present in products we use daily and, in the meantime, are part of our everyday life. Due to their exceptional properties (e. g., increase... - First measurements of halogenated coolants and foaming agents in the atmosphere
4th generation halogenated coolants and foaming agents have only been in use for a few years. They have replaced persistent greenhouse gases such as R134a, which were used in (car) air conditioning...
- Nanosafety research - there's room for improvement
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 o... - Graphene ribbons from differently doped sub-segments developed
Graphene is a semiconductor when prepared as an ultra-narrow ribbon - although the material is actually a conductive material. Researchers from Empa and the Max Planck Institute for Polymer Researc... - Producing hydrogen with sunlight
All over the world researchers are investigating solar cells which imitate plant photosynthesis, using sunlight and water to create synthetic fuels such as hydrogen. Empa researchers have developed... - The thinnest feasible membrane filters made of graphene
A new nano-membrane made out of the "wonder material" graphene is extremely light and breath-able. Not only can this open the door to a new generation of functional waterproof clothing, but also to... - Nanocellulose sponges to combat oil pollution
A new, absorbable material from Empa wood research could be of assistance in future oil spill accidents: a chemically modified nanocellulose sponge. The light material absorbs the oil spill, remain... - Antimony nanocrystals may be used as alternative anode materials in future high-energy-density batteries
The hunt is on - for new materials to be used in the next generation of batteries that may one day replace current lithium ion batteries. Today, the latter are commonplace and provide a reliable po... - No nano-dust danger from facade paint
After 42 months the EU research project "NanoHouse" has ended, and the verdict is a cautious "all clear" - nanoparticles in the paint used on building façades do not represent a particular health r...
- Unique surface analysis instrument
The 3D NanoChemiscope is a miracle of state-of-the-art analysis technology. As a further development of well-known microscopic and mass spectroscopic methods, it maps the physical and chemical surf... - Non-toxic flame retardants - Development of safe alternatives
Flame retardants are often extremely harmful to health. Despite this, they are found in many types of synthetic materials which would otherwise ignite quickly. Empa researchers have now succeeded i...
- Nanoparticle Test Handbook sets the standards
A new handbook has been published under Empa leadership which aims to unify European standards in nanoparticle research. It contains detailed regulations for the manufacture and analysis of specifi...
