This is a schematic of the functionalization of the nanoparticles along with photographic images of the water droplets on spray-coated microscope slides. An environmentally friendly superhydrophobic coating to superhydrophilic coating for antifogging and antifouling according to scientists at Swansea...
UT Austin researchers used a magnet and nanoparticles to separate oil from water in seconds.

When oil mixes with or enters into water, conventional methods of cleaning the water and removing the oil can be challenging,...
Polymeric pigments were produced by guided oxidation of peptide assemblies.

Scientists have long known that melanin -- the pigments that give color to skin, hair and eyes -- has numerous useful qualities, including providing protection from cancer-causing...
This is a figure illustrating that polymer crystallization speed can be used to control the spatial distribution of nanoparticles. Impurities (here, the nanoparticles) will become engulfed by the crystal if it grows too rapidly. However, when the rate slows,...
As a mouse moves, or translates, forward optical flow radiates around him from a single point in front. When the mouse rotates, optical flow is horizontal all the way around, appearing forward in one eye but backward in the...
Photosystems (PS) I and II are large protein complexes that contain light-absorbing pigment molecules needed for photosynthesis. PS II captures energy from sunlight to extract electrons from water molecules, splitting water into oxygen and hydrogen ions (H+) and producing...

In a recent paper published in PLOS One, Saint Louis University professor of physics Jean Potvin, Ph.D., and biologist Alexander Werth, Ph.D. at Hampden-Sydney College, detail for the first time how baleen whales use...
Innsbruck physicists have observed an intriguing oscillatory back-and-forth motion of a quantum particle in a one-dimensional atomic gas.

A ripe apple falling from a tree has inspired Sir Isaac Newton to formulate a theory that describes the motion...
In the new quantum test of the Einstein equivalence principle, free fall of atoms in quantum superpositions on different mass-energies, |a> and |b>, was compared to the free fall of atoms with a well-defined, classical mass-energy |a>. In all...
The flow of polaritons encounters an obstacle in the supersonic (top) and superfluid (bottom) regime.

Scientists have known for centuries that light is composed of waves. The fact that light can also behave as a liquid, rippling and...
Earlier calculations failed to find a 'fixed point' in three dimensions, or a spot where all the lines overlap (left). By taking these calculations one step further, Yaida was able to find the fixed point (right), showing that a...
