Laser-generated surface structures create extremely water-repellent metals
Scientists at the University of Rochester have used lasers to transform metals into extremely water repellent, or super-hydrophobic, materials without the need for temporary coatings.
Chemical dial controls attraction between water-repelling molecules
Fear of water may seem like an irrational hindrance to humans, but on a molecular level, it lends order to the world.
Engineers create 'superomniphobic' texture capable of repelling all liquids
(Phys.org) —A pair of researchers from the UCLA Henry Samueli School of Engineering and Applied Science has created the first surface texture that can repel all liquids, no matter what material the surface ...
Inspired by nature, scientists design protein-esque molecules to lock up carbon dioxide
For eons, marine organisms have taken in carbon dioxide dissolved in water and turned it into protective calcium carbonate layers, or seashells with the assistance of proteins. Inspired by these creatures ...
Surfactants do not harm the environment
When you take a shower and rinse the soap and shampoo off your body, the foam conveniently disappears between your toes and down the drain. Have you ever thought about what happens to the surfactants afterwards? ...
Quenching the world's water and energy crises, one tiny droplet at a time
In the Namib Desert of Africa, the fog-filled morning wind carries the drinking water for a beetle called the Stenocara.
New super waterproof surfaces cause water to bounce like a ball
(Phys.org) —In a basement lab on BYU's campus, mechanical engineering professor Julie Crockett analyzes water as it bounces like a ball and rolls down a ramp.
The complex physical mechanisms in real biomolecule motors
Computer simulations of relatively simple models provide clues to the complex physical mechanisms at work in real biomolecule motors.
Physicists break theoretical time barrier on bouncing droplets (w/ Video)
Those who study hydrophobic materials—water-shedding surfaces such as those found in nature and created in the laboratory—are familiar with a theoretical limit on the time it takes for a water droplet ...
A better trigger for targeted drug delivery
Biomolecular 'nanocarriers' formed by the careful assembly of protein subunits are common in nature and perform a range of essential roles in biological processes, powered by the biological energy carrier ...
Artificial muscle contracts and expands with changes in humidity
(Phys.org) —A small plastic strip can do "weight training" to effortlessly lifts many times its own weight, driven by cyclic changes in the humidity of the surrounding air. This strong "artificial arm" is based on the interaction ...
Researchers develop a way to cause static self-assembly using magnets and ferrofluids
Explained: Hydrophobic and hydrophilic
Sometimes water spreads evenly when it hits a surface; sometimes it beads into tiny droplets. While people have noticed these differences since ancient times, a better understanding of these properties, and ...
Unique shell design gives guillemot eggs an edge for living on the edge
Unique nano-structures on guillemot eggshells eggs enable them to survive precarious habitats, on exposed cliffs with no nest. A new study, to be presented at the Society for Experimental Biology meeting ...
