Nanoparticle-based aerogels combine the properties of traditional aerogels with those of nanoparticles, and hold promise for various applications following a function-led design.

Core/shell heterostructures provide controlled optical properties, tuneable electronic structure, and chemical stability due to an appropriate interface design.

Effective and gentle purification methods are essential for describing colloidal nanocrystal surface chemistry, which is key to optimizing nanocrystal technologies.

We develop a hybrid ligand exchange process to enhance both mobility and lifetime of carriers in nanocrystal thin films.

Cation-rich (100) and (111) facets of colloidal quantum dots could be greatly stabilized by dimerization or amine–anion co-passivation.

Rh(0)/Rh(III) core–shell nanoparticles, generated by surface oxidation with N-bromosuccinimide, exhibited high activity and excellent recyclability for cyclic carbonate synthesis.

Phase-stable perovskite CsPbI₃ nanocrystals have been prepared by replacing conventionally used oleic acid with a phosphinic acid in their synthesis.

The reaction of primary amines with carboxylate-capped InP clusters is found to remove indium carboxylate subunits from the cluster surface, resulting in a structural rearrangement to alleviate core strain and passivate phosphorus atoms.

The Au₃₈(SC₂H₄Ph)₂₄ nanocluster catalyzes the A³ coupling reaction with a turnover frequency significantly higher than those of conventional nanogold catalysts.

We employed quantitative NMR spectroscopy and spectrophotometric absorbance titration to study a quantum dot X-type ligand exchange reaction.

Herein, we designed vertically aligned TiO₂ nanotube arrays, in which a very thin disordered overlayer approximately a few nm thick was formed via a room-temperature solution process.

Ba_xSr_1−xTiO₃ perovskite nanocrystals, prepared by the vapor diffusion sol–gel method and characterized by state of the art surface techniques, display significantly different O–H stretching frequencies and adsorption properties towards CO₂ as a function of the alkaline earth composition (Ba vs. Sr).

We offer new insights into the roles played by surface capping in controlling the pattern of growth involving Pd cubic seeds and a HAuCl₄ precursor.

This paper reports the use of formic acid as a reducing agent for the shape-controlled synthesis of Pd nanocrystals with no chemisorption of CO on the surface, as confirmed by attenuated total reflection Fourier transform infrared (ATR-FT-IR) spectroscopy.

In this work, we present a new way to understand and influence the properties of quantum dots utilizing surface chemistry.
