Dermal silicone generators harvest the energy of muscle movements to produce static electricity.
Researchers have found a way to use lasers to cut nanostructure patterns into metal that make the material so water-repellent that H2O just bounces right off of it -- all without the use of chemical coatings.
The science could lead to rust- and ice-free metals and water-repellant electronics.
The technique resembles that used to create children's pop-up books, except instead of using paper, the researchers used materials such as silicon.
A new material called Prism can be programmed to display different colors and patterns in a way that consumes very little power.
A tiny device that detects nanoscale vibrations that occur inside microscopic beings.
Proposed anti-fraud technique would use lasers, nanoparticle strips and misbehaving photons.
This paper can be written on and erased more than 20 times with no loss in contrast and resolution.
