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.

New reagents selected for nickel extraction

More nickel can be produced more efficiently from Australia's low-grade laterite ores if the metal is directly extracted after leaching with nitric acid, research suggests.

Chemical cloud over Spanish town after factory accident

A chemical accident at a factory in Spain on Thursday injured three people and cloaked large swathes of the region in an orange chemical cloud, forcing over 60,000 people to stay indoors before it disappeared.

Synthesizing textiles from sugar

In the future, the clothes you wear could be made from sugar. Researchers at the Institute of Bioengineering and Nanotechnology (IBN) have discovered a new chemical process that can convert adipic acid directly from sugar.
