Charged surfaces in contact with liquids—such as biological cell walls or battery electrodes—attract oppositely charged ions from the liquid. This creates two distinct charged regions: the surface ...

Researchers have developed a new way to control and manipulate optical signals by embedding a liquid crystal layer into waveguides created with direct laser writing. The new devices enable ...

Fig. 1 (a) Typical intensity distribution obtained by rotating the second liquid crystal layer (LC2) in the in-situ state. (b) Intensity distribution obtained by rotating LC2 in the ex-situ state. (c) ...

The ice in a domestic freezer is remarkably different from the single crystals that form in snow clouds, or even those formed on a frozen pond. As temperatures drop, ice crystals can grow in a variety ...

“Follow the water” has long been the mantra of scientists searching for life beyond Earth. After all, the only known cradle of life in the cosmos is the watery planet we call home. But now there’s ...
