In a discovery that could eventually have implications for both health and industrial safety, researchers at Princeton University have found that common T-junction intersections in pipes can trap bubbles and other particles even if the materials appear to be flowing freely.
In his annual holiday lecture, Professor Howard Stone and his assistants used high-speed cameras, high-tech amplifiers and a host of audience participants to unveil the surprising way the world really works when things move faster than the eye can see.
Researchers at Princeton and in Beijing have used engineering calculations to determine how ancient workers moved an enormous block of stone to the Forbidden City where it became the palace's iconic Large Stone Carving.
How do bacteria communicate with each other? What do biofilms have in common with skyscrapers? This video features innovative research at the intersection of molecular biology and engineering.
Students conferred their semi-annual Excellence in Teaching Awards to professors and teaching assistants at a ceremony Feb. 21. The awards included a Lifetime Achievement Award to Professor Pablo Debenedetti.
The annual holiday science lecture led by Professor Howard Stone dazzled children who learned about amazing properties of light, and were often called upon to act out important concepts in physics.
In research initiated by an undergraduate, Princeton engineers discovered that elephants' hair is not merely a decorative feature for pulchritudinous pachyderms; it also plays an important role in how the giant beasts regulate their body temperatures.
Under a microscope, a tiny droplet slides between two fine hairs like a roller coaster on a set of rails until — poof — it suddenly spreads along them, a droplet no more. That instant of change, like the popping of a soap bubble, comes so suddenly that it seems almost magical. But describing it, and mapping out how droplets stretch into tiny columns, is key to understanding how liquids affect fibrous materials, from air filters to human hair. That knowledge could allow scientists
A study led by researchers at Princeton University has yielded insights into how liquid spreads along flexible fibers, which could allow for increased efficiency in various industrial applications.
Fundamentals of fluids Researchers in the lab of Howard Stone, the Donald R. Dixon ’69 and Elizabeth W. Dixon Professor of Mechanical and Aerospace Engineering, are applying a deep understanding of fluid flows to reveal the mechanics behind critical biological functions. In one project, Stone’s group found the unexpected formation of bacterial ribbons in the middle of flowing fluids, which has implications for understanding serious infections and has led to a collaboration with Bon
Howard A. Stone studies problems of engineering, physics and chemistry in the field of fluid mechanics. “Fluid mechanics is cool because it occurs everywhere around you,” Stone says.
How many different ways do creatures communicate with one another? Howard A. Stone, professor of mechanical and aerospace engineering, and Bonnie Bassler, professor of molecular biology, enlist the help of elementary-school students to explain the science of communication.
The 6th Annual Innovation Forum awarded $40,000 to help tech innovations get closer to the marketplace.
