Study discovers amazing electrical properties in polymers

(PhysOrg.com) -- Crystals and ceramics pale when compared to a material researchers at Oak Ridge National Laboratory discovered that has 10 times their piezoelectric effect, making it suitable for perhaps hundreds of everyday ...

Hunting for gaps

(PhysOrg.com) -- Researchers have developed a new model for the behavior of pedestrians and crowds. It can help to understand and prevent tragic crowd disasters, to develop better architectural designs and new navigation ...

Impact sensor provides athletic support

As athletes strive for perfection, sports scientists need to exploit every technological advance to help them achieve that goal. Researchers in New Zealand have now developed a new type of wearable impact sensor based that ...

Repulsive interactions

(PhysOrg.com) -- The recent state of the roads is a clear illustration of what happens when water freezes into crystals of ice. But despite its frequent occurrence, the crystallisation of water is remarkably difficult to ...

Metamaterials could reduce friction in nanomachines

(PhysOrg.com) -- Nanoscale machines expected to have wide application in industry, energy, medicine and other fields may someday operate far more efficiently thanks to important theoretical discoveries concerning the manipulation ...

Human crowds are best modeled by a 'visual neighborhood'

Human crowd dynamics are best predicted by a visual neighborhood model, based on the visual fields of each person in the crowd. Birds flock, fish school, and human crowds, too, move in a collective motion pattern. Understanding ...
