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.
Scorpions inspire scientists in making tougher surfaces for machinery
Taking inspiration from the yellow fattail scorpion, which uses a bionic shield to protect itself against scratches from desert sandstorms, scientists have developed a new way to protect the moving parts of ...
Korean researchers use graphene to create transparent loudspeakers
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 ...
The world's first Expansion/Deflection nozzle hybrid tested
(PhysOrg.com) -- Engineers at the University of Bristol and Airborne Engineering last month conducted a number of performance tests of their experimental hybrid rocket engine, called Firecrest.
Silent nozzle extinguisher does not harm hard disks
Siemens has developed a very quiet nozzle for gas extinguishing systems. The system is especially suitable for use in computer centers that store sensitive data. Thats because loud noise can cause hard ...

Revolutionary ultrasonic nozzle that will change the way water cleans
A team of scientists from the University of Southampton have developed a revolutionary ultrasonic attachment for taps, which massively enhances the ability of water to clean.
J-2X nozzle extension goes the distance
(Phys.org) -- NASA engineers conducted a 550-second test of the new J-2X rocket engine at Stennis Space Center in Mississippi on July 13. The J-2X engine will power the upper-stage of a planned two-stage Space ...
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 ...
