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 a decidedly ...

Microfountain pen draws minute patterns for live cells, circuits

Advances in intuitive microwriting devices that can print microstructures could pattern electric circuits and more. The setup, featuring a robot arm to hold the micropen, deposits ink onto the surface, much like writing by ...

Simplifying supersonic nozzle pressure monitoring

A bit of serendipity while carrying out a routine calibration led a researcher at Lawrence Berkeley National Laboratory's (Berkeley Lab) BELLA Center to discover a new method to measure the pressure of supersonic nozzles. ...

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 inside individual ...

Researcher use robot arm to print 3D sand structures

(Phys.org) -- Researchers from the Institute for Advanced Architecture of Catalonia have built a programmable robot arm with a nozzle for a hand that allows for building structures out of sand mixed with water and binding ...

Nozzle

A nozzle is a device designed to control the direction or characteristics of a fluid flow (especially to increase velocity) as it exits (or enters) an enclosed chamber or pipe via an orifice.

A nozzle is often a pipe or tube of varying cross sectional area, and it can be used to direct or modify the flow of a fluid (liquid or gas). Nozzles are frequently used to control the rate of flow, speed, direction, mass, shape, and/or the pressure of the stream that emerges from them.
