Non-Stick Surfaces That Turn On And Off

Researchers in New Jersey report development of a new type of non-stick material whose ability to shed liquids like water from a duck’s back can be turned on or off simply by flipping an electrical switch. The material, called “nanonails,” offers a wide-ra ...

The Mystery Of Glassy Water

Water has some amazing properties. It is the only natural substance found in all three states — solid, liquid and gas — within the range of natural Earth temperatures. Its solid form is less dense than its liquid form, which is why ice floats. It can absor ...

Nanoparticle Coating Means "Self-Cleaning" Wool And Silk Fabric

Wool skirts and silk ties may avoid those pricey trips to the dry-cleaner in the future and clean themselves, researchers in Australia and China suggest. They are reporting development of a nanoparticle coating that could lead to “self-cleaning” wool and s ...

Prototype For Nano-Newton Force Measuring Device

When chemists want to measure the bonding forces in molecules or other most minuscule forces very accurately, they have to calibrate their measuring instruments (for example the cantilevers, i.e. the measuring tips, of scanning force microscopes). And if i ...

Full Metal Alchemist: Researchers Magnetize Gold And Silver Atoms

An international team has achieved, by means of a controlled chemical process, that atoms of gold, silver and copper- intrinsically non-magnetic (not attracted to a magnet)- become magnetic. According to the research, the magnetism appears reduce the dimen ...
