A new model may shed new understanding on the phenomenon known as discontinuous shear thickening (DST), in which the resistance to stirring takes a sudden jump. Easily observed in a 'kitchen ...

Researchers are using ultrasonic waves to manipulate the viscosity of shear-thickening materials, turning solids to slush -- and back again. Researchers are using ultrasonic waves to manipulate the ...

Norman Wagner, the University of Delaware Unidel Robert L. Pigford Chair in Chemical Engineering at the University of Delaware, has received the 2018 Sustained Research Prize from the Neutron ...

August 13, 2006 Since warfare began, developing armor has been a balance between the need for protection and the need for comfort, flexibility and light weight. A new nanotechnology known as Shear ...

The next generation of protective equipment is looking a lot less bulky and a lot more fluid. Shear thickening fluids (STFs) are novel field-responsive materials that can be engineered to be useful ...

It expands, it contracts, it gets stronger, it lets up — it reacts to changing conditions in formidable and comfortable ways. And the adventures of shear-thickening fluid, invented by University of ...

A Polish firm is the latest to concoct unassuming-looking fluids that harden on impact, making for lighter, more flexible protection on the battlefield and beyond. Leslie Katz led a team that explored ...

If you’ve ever whacked the bottom of a ketchup bottle to get that tasty tomato goop flowing, you’ve put some serious physics to work. Ketchup is a non-Newtonian fluid. So are toothpaste, yogurt, ...

What do paint, dishwasher detergent, ketchup and blood have in common? All are composed of particles suspended in a carrier liquid and flow when stirred or forced, but remain thick or even gel-like at ...

If I were asked to define what a fluid is, I would most likely use the definition I learned in grade school: a state of matter that flows and takes the form of the container it is in. Similarly, a ...
