Gold-based passive heating for eyewear

Researchers at ETH Zurich have developed an ultrathin, gold-based transparent coating that is able to convert sunlight into heat. It can be applied to glass and other surfaces to prevent them from fogging. Applications for ...

A new template for nonspherical viral nanocages

In nature, viruses use nanocages to protect their genome. Some of these viruses can be disassembled into protein units to remove their genome. These protein units can then be reassembled into nanocages by other templates, ...
