TL;DR: It is found that optically pumped, two-dimensional arrays of plasmonic Au or Ag nanoparticles surrounded by an organic gain medium show directional beam emission, and behave as arrays of nanoscale light sources in the near-field.

TL;DR: Direct visualization of interactions between drug-loaded nanoparticles and the cancer cell nucleus and the nuclear phenotype via nuclear envelope invaginations could provide new insight for nuclear-targeted cancer therapy.

TL;DR: A new design for a room-temperature nanolaser based on three-dimensional (3D) Au bowtie NPs supported by an organic gain material is presented and ultrafast resonant energy transfer between photoexcited dye molecules and gap plasmons is confirmed on the picosecond time scale.

TL;DR: In this article, the first results from studies of liquid water microjets by soft X-ray absorption spectroscopy are presented, showing that a fine-structure pattern very similar to that found for gaseous water monomers is observed when the surface-selective total ion yield (TIY) is measured, but a broadened and blue-shifted spectrum emerges when detecting the bulk-sensitive total electron yield (TEY).

TL;DR: In this article, extended x-ray absorption fine structure spectroscopy of liquid microjets has been employed to observe the intermolecular O-O distance undergo a 5.9% expansion at the liquid water interface, in contrast to liquid methanol for which there is a 4.6% surface contraction.
