New approach to measuring stickiness could aid micro-device design

Brown University engineers have devised a new method of measuring the stickiness of micro-scale surfaces. The technique, described in Proceedings of the Royal Society A, could be useful in designing and building micro-electro-mechanical ...

Quantum tunnelling in water opens the way to improved biosensing

Researchers at the University of Sydney have applied quantum techniques to understanding the electrolysis of water, which is the application of an electric current to H2O to produce the constituent elements hydrogen and oxygen.

A beautiful wing design solution inspired by owl feathers

Many species of owl are able to hunt without being heard by their prey by suppressing the noise of their wings at sound frequencies above 1.6 kilohertz (kHz)—including the range at which human hearing is most sensitive.

Mathematicians ask: What's in a ripple?

When a fluid or a gas experiences a sudden disturbance, such as a change in pressure or elevation, it often gives rise to a phenomenon known as an undular bore, which consists of a series of rapid oscillations that propagate ...

Experimental method measures robustness of quantum coherence

Researchers at the UAB have come up with a method to measure the strength of the superposition coherence in any given quantum state. The method, published in the journal Proceedings of the Royal Society A, is based on the ...

Model suggests fear of crime is contagious

(Phys.org)—A pair of researchers at University College London has found evidence suggesting that fear of crime is contagious. In their paper published in Proceedings of the Royal Society A, Rafael Prieto Curiel and Steven ...

'Field patterns' as a new mathematical object

University of Utah mathematicians propose a theoretical framework to understand how waves and other disturbances move through materials in conditions that vary in both space and time. The theory, called "field patterns," ...
