The authors carry out ligand exchange reaction replacing bulky insulating org. ligands with inorg. chalcogenidometallate clusters in nanocrystal assemblies floating at the gas-liq. interface. The mobility of the nanocrystals allows lattice contraction with ...
Described is an electrochromic nanocomposite film comprising a solid matrix of an oxide based material, the solid matrix comprising a plurality of transparent conducting oxide (TCO) nanostructures dispersed in the solid matrix and a lithium salt dispersed ...
Chem. degrdn. at electrode/electrolyte interfaces in high-energy storage devices, such as Li-ion batteries, imposes durability challenges that affect their life and cost. In oxide electrodes, degrdn. is linked to the presence of redox active transition met ...
Org. ligands (or surfactants) are key in detg. colloidal nanocrystal structure and, therefore, function. In addn. to their more traditional role as surface passivating agents impacting nanocrystal size and shape, surfactants can also behave as active reage ...
The authors report here the 1st solid-state, NIR-selective electrochromic devices. Crit. to device performance is the arrangement of nanocrystal-derived electrodes into heteromaterial frameworks, where hierarchically porous ITO nanocrystal active layers ar ...
Integrating nanocrystals (NCs) into magnetic tunnel structures is of considerable interest due to expectation of novel properties from their spin selective transport and single electron features. Superstructures by colloidal NCs having translational and or ...
A review. Colloidal nanocrystal frameworks (CNFs) are a modular class of mesostructured porous materials, which are assembled from pre-formed nanocrystal building units using suitably designed block copolymer architecture-directing agents. The functional a ...
Herein, we report a colloidal wet-chem. approach enabling control on dopant concn. and location in a nanocrystal host lattice. Growth-doping and nucleation-doping, driven by primary and tertiary amines, resp., were identified as predominant doping mechanis ...
A review. The authors describe how recent insights into colloidal nanocrystal (NC) surface chem. have fueled dramatic progress in functional mesostructures. The simplest mesoscale assemblies considered are networks of NCs constructed by in situ replacement ...
This article describes the carbon-free titania composite battery electrodes constructed from anisotropic, rod-shaped nanocrystals has very high and stable capacities, as well as outstanding rate capability, when compared to carbon-contg. counterparts. Mono ...
