A new study explores the counter-intuitive behavior of a microgel composed of soft polymer blobs Being a physicist offers many perks. For one, it allows an understanding of the substances ubiquitous in everyday industrial products such as emulsions, gels, granular pastes or foams. These are known for their intermediate behaviour between fluid and solid. Paint, for example, can be picked up on a paintbrush without flowing and spread under the stress of the brush stroke like a fluid....

It's easy to get in a jam. But it's much harder to explain exactly how or when it started. Scientists still aren't sure what causes clogs in flowing macroscopic particles, like corn, coffee beans and coal chunks. But new experiments by Duke physicist Robert Behringer and his colleagues suggest that when particles undergo a force called shear strain, they jam sooner than expected. The results appear in the Dec. 15 issue of Nature. Shear strain is sort of like cupping sand between your...

Hit it hard and it will fracture like a solid"¦ but tilt it slowly and it will flow like a fluid. This is the intriguing property of a type of "Ëœcomplex fluid' which has revealed "Ëœnew physics' in research by scientists at The University of Nottingham. The new findings will be highly useful to the manufacturing industry because the processing and dispensing of everyday products like toothpaste, cosmetics, pharmaceuticals and foodstuffs depends on an understanding...
