An optical coating like no other

For more than a century, optical coatings have been used to better reflect certain wavelengths of light from lenses and other devices or, conversely, to better transmit certain wavelengths through them. For example, the coatings ...

Imaging a molecular switch

Scanning probe microscopes like the scanning tunneling microscope and the atomic force microscope give researchers valuable information about individual molecules. One of the most interesting areas of research is molecular ...

How metal atoms can arrange themselves on an insulator

In order to produce tiny electronic memories or sensors in the future, it is essential to be able to arrange individual metal atoms on an insulating layer. Scientists at Bielefeld University's Faculty of Chemistry have now ...

Nanocrystals that eradicate bacterial biofilms

The COVID-19 pandemic is raising fears of new pathogens such as viruses or drug-resistant bacteria. On this note, a Korean research team has recently drawn attention for developing the technology for removing antibiotic-resistant ...

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 ...
