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 ...
Bionanotechnology has new face, world-class future
Imagine the marriage of hard metals or semiconductors to soft organic or biological products. Picture the strange, wonderful offspring -- hybrid materials never conceived by Mother Nature.
Spiderman robot spins draglines to cross open space (w/ video)
Friction almost vanishes in microscale graphite
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 ...
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.
Metal surface can repel electric charges
It's raining pentagons
This week's Nature Materials (09 March 2009) reveals how an international team of scientists led by researchers at the London Centre for Nanotechnology (LCN) at UCL have discovered a novel one dimensional ice ch ...
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 ...
Engineers gain insight into turbulence formation and evolution in fluids
in the patterns that natural gas makes as it swirls through a transcontinental pipeline or in the drag that occurs as a plane soars through the sky. Reducing such turbulence on say, an airplane wing, would ...
Boiling breakthrough: Nano-coating doubles rate of heat transfer
By adding an incredibly thin coating of alumina to a metal surface, researchers at the Georgia Institute of Technology have doubled the rate that heat travels from a solid surface such as a pot on a stove into ...
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.
NASA's Dawn collects a bounty of beauty from Vesta
(PhysOrg.com) -- A new video from NASA's Dawn spacecraft takes us on a flyover journey above the surface of the giant asteroid Vesta.
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 ...
