Turning fish waste into quality carbon-based nanomaterial

Thanks to their low toxicity, chemical stability, and remarkable electrical and optical properties, carbon-based nanomaterials are finding more and more applications across electronics, energy conversion and storage, catalysis, ...

Century-old electrochemistry law gets update

The Gouy-Chapman theory describes what happens near an electrode when it is in contact with a salt solution, but this description does not match reality. Researcher Kasinath Ojha, assistant professor Katharina Doblhoff-Dier ...

Surface chemistry reveals corrosive secrets

One can easily see with the naked eye that leaving an old nail out in the rain causes rust. What does require the keen eyes and sensitive nose of microscopy and spectroscopy is observing how iron corrodes and forms new minerals, ...

Researchers first to link silicon atoms on surfaces

Materials such as gallium arsenide are extremely important for the production of electronic devices. As supplies of it are limited, or they can present health and environmental hazards, specialists are looking for alternative ...

Cathodic corrosion—devastating but predictable

An indian stepwell on a nanoscale. That is what postdoc Nakkiran Arulmozhi calls the pattern he saw when he corroded a special kind of platinum crystal. The unique images show the destructiveness of the process, but also ...

The fundamental chemistry behind electrocatalytic water splitting

Transitioning to a sustainable energy economy requires electrocatalytic methods to convert electrical energy to chemical energy and feedstocks. A team of researchers from TU Berlin, ETH Zurich, the National Research Council—Institute ...
