TL;DR: Shell-isolated nanoparticle-enhanced Raman spectroscopy is reported, in which the Raman signal amplification is provided by gold nanoparticles with an ultrathin silica or alumina shell, which significantly expands the flexibility of SERS for useful applications in the materials and life sciences, as well as for the inspection of food safety, drugs, explosives and environment pollutants.

TL;DR: Density functional theory calculations reveal that the most significant spectral change seen for a gold-4,4′-bipyridine-gold junction results from the deformation of the pyridine ring in contact with the drain electrode at high voltage, and these calculations suggest that a stronger bonding interaction between the molecule and the drain may account for the nonlinear dependence of conductance on bias voltage.

TL;DR: Shell-isolated nanoparticle-enhanced Raman spectroscopy was used to investigate ORR processes on the surface of novel bimetallic Pt3Co nanocatlyst satellite structures and shows SHINERS is a promising technique for the real-time observation of catalytic processes.

TL;DR: In situ Raman spectroscopy has been employed to investigate ORR processes at high-index Pt(hkl) surfaces containing the [011 ̅] crystal zone and it was deduced that the difference in adsorption of OOH athigh-index surfaces has a significant effect on the ORR activity.

TL;DR: The results suggest that coupling is surprisingly on the same order of magnitude or even larger in conductance measurements whereas electron transfer occurs on larger distances than in transient electrochemistry.
