Human eye inspires clog-free ink jet printer invention
Clogged printer nozzles waste time and money while reducing print quality. University of Missouri engineers recently invented a clog-preventing nozzle cover by mimicking the human eye.
Images capture split personality of dense suspensions
Stir lots of small particles into water, and the resulting thick mixture appears highly viscous. When this dense suspension slips through a nozzle and forms a droplet, however, its behavior momentarily reveals ...
Researchers create world's smallest reaction chamber
The world's smallest reaction chamber, with a mixing volume measured in femtolitres (million billionths of a litre), can be used to study the kind of speedy, nanoscale biochemical reactions that take place ...

Researchers develop prototype automated pavement crack detection and sealing system
Sealing cracks in roadways ensures a road's structural integrity and extends the time between major repaving projects, but conventional manual crack sealing operations expose workers to dangerous traffic and ...
Superhydrophobic surface helps researchers develop optical displays from water and air (w/ Video)
(Phys.org) -- For many years, scientists have been pursuing ways to mimic the perplexing capability of the lotus leaf to repel water. Lotus leaves hate water so much that droplets effortlessly roll off the ...
