An innovative micro-pump makes it possible for tiny quantities of liquid – such as medicines – to be dosed accurately and flexibly. Active composites and an electronic control mechanism ensure that the low-maintenance pump works accurately – both forwards and backwards.

The Particle Whisperers

As many parents know, it's often easier to keep your kids under control by exerting less authority rather than more. A child who fidgets uncontrollably in a confining booster seat, for example, may be perfectly content on a plain old chair. A team of physicists at the Universitat de Barcelona has found that the same is true in controlling the movement of particles suspended in liquids.

Standard microscopy and visible light imaging techniques cannot peer into the dark and murky centers of dense-liquid jets, which has hindered scientists in their quest for a full understanding of liquid breakup in devices such as automobile fuel injectors.

How some solids mimic liquids on nanoscale

A University of Waterloo physics and astronomy research team, in a paper to be published Friday in Science Magazine, shows how some solids behave like liquids on the nanoscale.

Toward improved non-stick surfaces at flip of a switch

Researchers in New Jersey report development of a new type of non-stick material whose ability to shed liquids like water from a duck’s back can be turned on or off simply by flipping an electrical switch.

Portable test promises to help detect flammable liquids in arson

Researchers in Ohio are reporting development of an inexpensive portable test for accurately identifying flammable liquids used in arson — the leading cause of fires and the second leading cause of fire deaths in the United States. Their study is scheduled for the current issue of ACS’ Analytical Chemistry, a semi-monthly journal.

Drawing Nanoscale Features Fast, Easy Way

Scientists at the Georgia Institute of Technology have developed a new technique for nanolithography that is extremely fast and capable of being used in a range of environments including air (outside a vacuum) and liquids. Researchers have demonstrated the technique, known as thermochemical nanolithography, as a proof of concept.

Emory physicist opens new window on glass puzzle

When most people look at a window, they see solid panes of glass, but for decades, physicists have pondered the mysteries of window glass: Is glass a solid, or merely an extremely slow moving liquid" An Emory University research team led by physicist Eric Weeks has yielded another clue in the glass puzzle, demonstrating that, unlike liquids, glasses aren't comfortable in confined spaces.
