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 ...

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 ...

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 ...

Researchers using a high-speed camera have captured the moments a fluid reacts like a solid, through a new method of fluid observation under pressurized conditions. They examined fluids that have a ...

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 ...

(Nanowerk News) In things thick and thin: Cornell physicists explain how fluids -- such as paint or paste -- behave by observing how micron-sized suspended particles dance in real time. Using ...

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 ...

Fluid materials are classified broadly as simple and structured fluids. Simple fluids are materials consisting of a homogenous phase such as a pure substance or a solution. Materials consisting of ...

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

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, ...
