A strategy to control phase selectivity in templated zeolite synthesis
Zeolites, groups of minerals comprising of hydrated aluminosilicates, are known to be highly promising materials for a number of applications. For instance, they can be used as catalysts, cation exchangers and molecular sieves.
Tiny lasers acting together as one: Topological vertical cavity laser arrays
Israeli and German researchers have developed a way to force an array of vertical cavity lasers to act together as a single laser—a highly effective laser network the size of a grain of sand. The findings are presented ...

Study unveils the minimum temperature for droplets levitating from smooth surfaces
The Leidenfrost effect is a well-known physical phenomenon first discovered in 1756. It occurs when a liquid is in the proximity of a surface that is significantly warmer than its boiling point. This produces an insulating ...
Come on in, the water is superionic
The interiors of Uranus and Neptune each contain about 50 000 times the amount of water in Earth's oceans, and a form of water known as superionic water is believed to be stable at depths greater than about one-third of the ...

Grabbing magic tin by the tail
Atomic nuclei have only two ingredients, protons and neutrons, but the relative number of these ingredients makes a radical difference in their properties. Certain configurations of protons and neutrons, with "magic numbers" ...

Can we see quantum correlations at the macroscopic scale?
One of the most fundamental features of quantum physics is Bell nonlocality: the fact that the predictions of quantum mechanics cannot be explained by any local (classical) theory. This has remarkable conceptual consequences ...

First glimpse of hydrodynamic electron flow in 3D materials
Electrons flow through most materials more like a gas than a fluid, meaning they don't interact much with one another. It was long hypothesized that electrons could flow like a fluid, but only recent advances in materials ...
