Achieving dynamic imaging of interfacial electrochemistry

A research team led by Prof. Liu Xianwei from the Department of Environmental Science and Engineering of University of Science and Technology of China (USTC) of the Chinese Academy of Science (CAS) has made progress in the ...

Fondant: Where baking and thermodynamics mix

With their unique appearance, texture, and mouthfeel, fondants have intrigued bakers and physicists for years. They present an appetizing enigma in the world of confectionery, an intriguing combination of sugar, water, and ...

Examining a nanocrystal that shines on and off indefinitely

In 2021, lanthanide-doped nanoparticles made waves—or rather, an avalanche—when Changwan Lee, then a Ph.D. student in Jim Schuck's lab at Columbia Engineering, set off an extreme light-producing chain reaction from ultrasmall ...

New nanoparticle source generates high-frequency light

High-frequency light is useful. The higher the frequency of light, the shorter its wavelength—and the shorter the wavelength, the smaller the objects and details the light can be used to see.
