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 new ways of controlling ...

Water droplets prefer the soft touch

(Phys.org) —Researchers have found a way to drive water droplets along a flat surface without applying heat, chemicals, electricity, or other forces: All that's required is varying the stiffness of the surface in the desired ...

Light-carved 'nano-volcanoes' hold promise for drug delivery

(Phys.org) —Researchers from North Carolina State University have developed a method for creating "nano-volcanoes" by shining various colors of light through a nanoscale "crystal ball" made of a synthetic polymer. These ...

Inventor creates Card Beams with 3D printer

What are card beams, you may ask? They are the building toy that allows you to build gravity-defying houses of cards with the help of friction, gravity, and two types of beams - the cap and the connector.

Nothing fishy about swimming with same-sized mates

Have you ever wondered why, and how, shoals of fish are comprised of fish of the same size? According to new research by Ashley Ward, from the University of Sydney in Australia, and Suzanne Currie, from Mount Allison University ...

Transforming noise into mechanical energy at nano level

A team of researchers at the Freie Universität Berlin, co-ordinated by José Ignacio Pascual, have developed a method that enables efficiently using the random movement of a molecule in order to make a macroscopic-scale ...

Lava dots: Scientists make hollow, soft-shelled quantum dots

(Phys.org)—Serendipity proved to be a key ingredient for the latest nanoparticles discovered at Rice University. The new "lava dot" particles were discovered accidentally when researchers stumbled upon a way of using molten ...
