Three-dimensional (3D) writing is a promising approach to realize stretchable electronics, but is so far limited to microscale features. We developed accurate 3D writing for highly stretchable organic nanowire arrays using a nanoscale polymer meniscus. Spe ...
Native coordinating ligands acquired during the chem. synthesis of colloidal nanocrystals are optimized primarily for their ability to exert control over nanocrystal size, compn., morphol., and dispersibility, and not necessarily for their final applicatio ...
The properties of metal oxide nanocrystals in energy-related devices are strongly dependent on the presence and chem. nature of ligands at their surface, and the architectures they assume in electroactive layers. A comprehensive strategy to control these a ...
The properties of tasked nanocrystals in energy-related devices are strongly dependent on the presence and chem. nature of ligands at their surface, and the architectures they assume in electroactive layers. Here we will describe an exceptionally versatile ...
Zinc oxides (ZnO) nanowires were successfully deposited on plastic low-power micro-hotplates using the thermal oxidation technique. Metallic zinc layer was deposited on the sensing transducer by RF magnetron sputtering and then oxidized in a controlled atm ...
The properties of metal oxide nanocrystals in energy-related devices are strongly dependent on the presence and chem. nature of ligands at their surface, and the architectures they assume in electroactive layers. The article presents a comprehensive strate ...
The "extra" electrons in colloidal n-type ZnO nanocrystals formed by aliovalent doping and photochem. redn. are compared. Whereas the two are similar spectroscopically, they show very different electron-transfer reactivities, attributable to their differen ...
TiO2, ZnO nanoparticulate(-np), and ZnO-nanorod(-nr) electrodes have been modified with FeS2 (pyrite) nanoparticles. Quantum size effect is manifested by a blue shift in both absorption and photocurrent action spectra. PIA (photoinduced absorption spectros ...
Ole-ain't: Trialkyl oxonium salts are universal reagents for native-ligand stripping of carboxylate- (e.g., oleate-), phosphonate-, and amine-passivated nanocrystal thin films and dispersions to give bare or BF 4 -/DMF-passivated surfaces. Meerwein-activat ...
Mild and general alumina promoted hydrolysis conditions for converting α-iminonitriles into carboxamides have been developed. In combination with the oxidative three-component Strecker reaction, the one-pot direct amidation of aldehydes and alcohols is rep ...
