New, rapid mechanism for atmospheric particle formation

Carnegie Mellon University researchers working with an international team of scientists have discovered a previously unknown mechanism that allows atmospheric particles to very rapidly form under certain conditions. The research, ...

Growing nitrogen footprint threatens our air, water and climate

A new study from Columbia University finds that nitrogen emissions from agricultural production in the tropics is likely to increase and, in some cases, overtake temperate climates, exposing more people to polluted air and ...

Discovery of an unusual protein

Nitrogen is an essential component of life. For example, it is required for the production of proteins. Boran Kartal, head of the Microbial Physiology group at the Max Planck Institute for Marine Microbiology in Bremen, studies ...

Can citric acid be a green alternative to protecting steel?

Nitric acid is currently the most widely used passivating solution to protect stainless steel from corrosion in industrial applications. But nitric acid is dangerous in multiple environmental, safety, and processes, due to ...

Exploring greener approaches to nitrogen fixation

About half of the nitrogen in our bodies today comes from bacteria via the enzyme nitrogenase, which converts, or "fixes," unreactive nitrogen gas in the atmosphere into a form that plants can use for growth. The other half ...

Finding trace material in waste materials

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 ...

Snatching at the cradle of life

Silence of the WA outback key in detecting low-frequency radio waves and, maybe, the precursors of life itself.
