Double-layered catalyst generates more hydrogen

Hydrogen-generating catalysts can create synergistic effects when different materials are layered with their unique properties. Recently, a Korean research team has developed a technology to enhance the hydrogen generation ...

Researchers develop 'corrosion-free' copper thin films

Copper (Cu) is of fundamental importance to our daily lives due to its excellent electrical conductivity, as well as other valuable physical properties, such as the ability to draw copper into thin wires. Cu is the metal ...

Scientists uncover simple strategies for keeping foams on walls

Researchers from Tokyo Metropolitan University have uncovered a unique mechanism by which foams on walls drain and slip over time. They showed how a foam can lose liquid via "pinch-off," like droplets from a faucet, finding ...

Cellular tornadoes sculpt organs

How are the different shapes of our organs and tissues generated? To answer this question, a team from the University of Geneva (UNIGE), Switzerland, forced muscle cells to spontaneously reproduce simple shapes in vitro. ...

The tiny structures that mimic a cell's natural environment

When biologists study cells under a microscope, they look at them on flat surfaces that are nothing like the environment inside the human body. Now, researchers at NTNU have found a way to mimic some aspects of a cell's native ...

Color-sorting metalenses boost imaging sensitivity

Researchers have shown that newly designed pixel-scale metasurface lenses—flat surfaces that use nanostructures to manipulate light—can be used to make imaging sensors that are roughly three times more sensitive than ...

Why food sticks to nonstick frying pans

Despite the use of nonstick frying pans, foods will sometimes get stuck to a heated surface, even if oil is used. The results can be very messy and unappetizing.
