    摘要: Reagent complexes have two or more elements, formally in oxidation state zero, complexed with a hydride molecule. Complexation with the hydride molecule may be evidenced by shifts to lower binding energies, of one or more electrons in each of the two or more elements, as observed by x-ray photoelectron spectroscopy. The reagents can be useful for the synthesis of multi-element nanoparticles. Preparation of the reagents can be achieved by ball-milling a mixture that includes powders of two or more elements and a hydride molecule.

    摘要: The present invention provides a heat treatment method, particularly a heat treatment method in which a protective layer is directly applied onto a precursor to ensure that the precursor on each portion of the substrate is treated based on substantially the same conditions so that the quality of the prepared product layer is improved. The method of the present invention comprises: (1) providing a substrate; (2) applying a precursor onto the surface of the substrate; (3) covering the precursor-applied substrate with a protective layer to bring the substrate and the protective layer into direct contact; (4) placing the substrate obtained from step (3) into a heat chamber for heat treatment; and (5) removing the protective layer. A product prepared by said heat treatment method is also provided.

    摘要: Disclosed herein is a method of purifying and doping a population of semiconductor nanocrystals. The method includes mixing the population of semiconductor nanocrystals having a first material system and a first ligand with a set of particles in the presence of a first solvent, the set of particles having a second material system which is different from the first material system and a second ligand which is different from the first ligand, to form a mixture. The method also includes facilitating a ligand exchange and an ionic exchange in the mixture, altering the first material system of the population of semiconductor nanocrystals to a third material system, different from the first material system and the second material system. The method includes sonicating the mixture and isolating the population of semiconductor nanocrystals having the third material system and the second ligand from the mixture.

    摘要: The present invention provides a method of exfoliating a layered material (e.g., transition metal dichalcogenide) to produce nano-scaled platelets having a thickness smaller than 100 nm, typically smaller than 10 nm. The method comprises (a) dispersing particles of a non-graphite laminar compound in a liquid medium containing therein a surfactant or dispersing agent to obtain a stable suspension or slurry; and (b) exposing the suspension or slurry to ultrasonic waves at an energy level for a sufficient length of time to produce separated nano-scaled platelets. The nano-scaled platelets are candidate reinforcement fillers for polymer nanocomposites.
