The faradaic efficiency of CO2 electroreduction is significantly affected by the thickness of Pd nanoshells on Au cores. The ratio of hydrogen evolution to CO2 reduction was determined by differential electrochemical mass spectrometry. Decreasing the Pd shell thickness from 10 to 1 nm leads to a twofold increase in faradaic efficiency.

metal nanoshells consists of a dielectric core surrounded by a thin noble metal shell, possess unique optical properties that render nanoshells attractive for use in different technologies. this paper reports a facile method for growth of small gold nanoparticles on the functionalized surface of larger silica nanoparticles. mono-dispersed silica particles and gold nanoparticles were prepared by...

Branched Au Nanoshells Out-of-equilibrium self-assembly of metal nanoparticles achieving 3D structures with controlled morphology is still rare. In article number 2206712, Claudia Pigliacelli, Pierangelo Metrangolo, and co-workers adopt a peptide-gold superstructure as template to control the out-of-equilibrium nanoparticles, obtaining transient branched Au-nanoshell stabilized by surfactant. T...

• Two low-cost hollow silica nanoparticle synthesis routes. Scalable, general production of soft ceramics by high-shear mechanical mixing. An effective – fiberglass crosslinked network for thermal insulation. Ultralow conductivity 0.023 W -1 m K with robust flexibility. Hollow-structured materials show promise in insulation because the shells encapsulating gaseous voids can interrupt heat trans...

We report a general method for the synthesis of hollow structures of a variety of functional inorganics by partial sintering of mesoporous nanocrystal aggregates. The formation of a thin shell initiates the transport of mass from the interior leading to growth of the shell. The principles are general and the hollow structures thus produced are attractive for many applications including catalysi...

We demonstrate a strategy for label-free protein detection through monitoring the Surface Enhanced Raman Spectrum of an aptamer probe attached to a gold nanoshell. Low limit of detection and minimal non-specific binding show potential for in vitro and in vivo assays.
