TL;DR: The irradiation of gold nanorod colloids with a femtosecond laser can be tuned to induce controlled nan orod reshaping, yielding colloid clusters with exceptionally narrow localized surface plasmon resonance bands.

TL;DR: Surfactant-assisted seeded growth of metal nanoparticles (NPs) can be engineered to produce anisotropic gold nanocrystals with high chiroptical activity through the templating effect of chiral micelles formed in the presence of dissymmetric cosurfactants.

TL;DR: It is demonstrated that the reproducibility and reliability of colloidal gold nanorod (AuNR) synthesis can be greatly improved by disconnecting the symmetry-breaking event from the seeded growth process, providing a robust route for the preparation of high quality AuNR colloids with tunable morphology, size, and optical response in a reproducible and scalable manner.

TL;DR: This study shows that the two distinct surfaces bounding the film behave at small wavelengths as atomically rough and independent ice-water and water-vapor interfaces, but for long wavelengths, the two surfaces couple, large scale parallel fluctuations are inhibited, and the ice-v Vapor interface becomes smooth.

TL;DR: Large-scale computer simulations are used to characterize the ice surface and identify a sequence of previously unidentified phase transitions on the main facets of ice crystallites, finding that as temperature is increased, the crystal surface transforms from a disordered phase with proliferation of steps to a smooth phase with small step density.
