Water glides freely across 'nanodrapes' made from the world's thinnest material

(Phys.org) —Engineering researchers at Rensselaer Polytechnic Institute have developed a new drape made from graphene—the thinnest material known to science—which can enhance the water-resistant...

New surface treatment stops scale buildup

Scale, as these deposits are known, causes inefficiencies, downtime, and maintenance issues. In the oil and gas industry, scale has sometimes led to the complete shutdown, at least temporarily, of...

Scientists challenge classical phenomenon that water always completely wets...

Viewed macroscopically at room temperature, when water contacts other water, it will spread out and finally both mix together. In 2009, Chinese researchers first reported observing the formation of a...

Engineers use liquid drops to make solids stiffer

(Phys.org)—Engineers at Yale University have discovered that the stiffness of liquid drops embedded in solids has something in common with Goldilocks: While large drops of liquids are softer than the...

An expression for droplet deformation simplifies calculations for a wide...

A simple formula that describes the initial deformation of a droplet as it hits a solid surface is likely to help to model droplet behavior in a variety of different contexts, shows new research by...

Biodegradable absorbent from water lily to attend oil spills

The water lily transformed from a plague to the main ingredient of a biodegradable absorbent that resolves spills or leaks of hydrocarbons, oils and other industrial substances, both in solid surfaces...

Discovery about how surface gradients influence droplet behavior may enable...

Studies of the impact a droplet makes on solid surfaces hark back more than a century. And until now, it was generally believed that a droplet's impact on a solid surface could always be separated into...

New deposition technique enhances optoelectronic properties of lasers

A simple new electron-beam multilayer deposition technique for creating intracavity contacts—an important component of gallium nitride-based (III-nitride) vertical-cavity surface-emitting lasers...

Investigating how droplets move around on a surface shows us why it is...

Not everyone ponders sets of partial differential equations when watching droplets slide down a window on a rainy day, but, thanks to new research from A*STAR, those who are so inclined now have what...

Flow phenomena on solid surfaces

Physicists from Saarland University and the ESPCI in Paris have shown how liquids on solid surfaces can be made to slide over the surface a bit like a bobsleigh on ice. The key is to apply a coating at...

Fluid dynamics model accurately predicts how bubbles impact on solid surfaces

Bubbles are an essential part of many industrial applications including foam formation, water purification, and oil and gas extraction. To understand the effects of bubbles in these systems, A*STAR...

Hop, skip and a jump: Researchers reveal molecular search patterns

Like an albatross scanning for pods of squid in a vast ocean, molecules on solid surfaces move in an intermittent search pattern that provides maximum efficiency, according to new research from the...

What is the surface of Neptune like?

As a gas giant (or ice giant), Neptune has no solid surface. In fact, the blue-green disc we have all seen in photographs over the years is actually a bit of an illusion. What we see is actually the...

Physicists generate ocean vortices in a glass of water

Scientists from a number of Russian universities, including MIPT, have studied previously neglected phenomena and determined the cause of liquid vortex flow formed by surface waves. The results of the...

New method of studying environmental toxins

In 1986, Gordon Brown used SLAC's Stanford Synchrotron Radiation Lightsource (SSRL) to visualize something no one had ever seen before: the exact way that atoms bond to a solid surface. The work...
