Tiny lasers from a gallery of whispers  

Whispering gallery mode resonators rely on a phenomenon similar to an effect observed in circular galleries, and the same phenomenon applies to light. When light is stored in ring-shaped or spherical active resonators, the waves superimpose in such a way that it can result in laser light. Investigators now report a new type of dye-doped WGM micro-laser that produces light with tunable wavelengths.

Coatings needed for concentrating solar power  

Next-generation concentrating solar power (CSP) plants require high-temperature fluids, like molten salts, in the range of 550-750 degrees Celsius to store heat and generate electricity. At those high temperatures, however, the molten salts eat away at common alloys used in the heat exchangers, piping, and storage vessels of CSP systems. New research is aimed at mitigating corrosion levels in CSP plants with nickel-based coatings.

Just squeeze in -- when spaces are tight, nature loosens its laws  

It turns out that when they're in a hurry and space is limited, ions, like people, will find a way to cram in -- even if that means defying nature's norms. Researchers have now shown that the charged particles will actually forgo their 'opposites attract' behavior, called Coulombic ordering, when confined in the tiny pores of a nanomaterial.

An original method of cooling ions could have new and interesting uses  

When investigating atoms, scientists face a challenge: At room temperature, individual atoms in a gas have kinetic energy, and fly around at large velocities. Temperature is, in essence, the relative movement between atoms; thus the goal of getting the atoms to have small relative velocities involves freezing them to extremely cold temperatures. A group has now developed new universal method for cooling ions.
