From a distance Saturn seems to exude an aura of serenity and peace.
Stain-free, self-cleaning clothing on the horizon
(Phys.org) —Since 2011, the Harvard research team that created Slippery Liquid-Infused Porous Surfaces has demonstrated a spate of sleek applications for the super-slick coating known as SLIPS, which repels ...
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 properties ...
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 operating ...
Sweet success: Study finds way to catalyze more sugars from biomass
(Phys.org) —Catalysis may initiate almost all modern industrial manufacturing processes, but catalytic activity on solid surfaces is poorly understood. This is especially true for the cellulase enzymes ...
Watching fluid flow at nanometer scales: Researchers find that tiny nanowires can lift liquids as effectively as tubes
Imagine if you could drink a glass of water just by inserting a solid wire into it and sucking on it as though it were a soda straw. It turns out that if you were tiny enough, that method would work just fine—and wouldn't ...
The quantum secret to alcohol reactions in space
Chemists have discovered that an 'impossible' reaction at cold temperatures actually occurs with vigour, which could change our understanding of how alcohols are formed and destroyed in space.
Solved: The mystery of the nanoscale crop circles
(PhysOrg.com) -- Almost three years ago a team of scientists at the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) was performing an experiment in which layers of gold mere ...
An expression for droplet deformation simplifies calculations for a wide range of applications
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 A*STAR.
The Sun's almost perfectly round shape baffles scientists
(Phys.org) -- The sun is nearly the roundest object ever measured. If scaled to the size of a beach ball, it would be so round that the difference between the widest and narrow diameters would be much less ...
Rethinking surface tension
(Phys.org) —If you've ever watched a drop of water form into a bead or a water strider scoot across a pond, you are familiar with a property of liquids called surface tension.
