- 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 ...

- 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 ...
