Provided is a method for manufacturing a spherical particle material in which the particle size distribution is easily controlled. This method has: a granulation step of granulating a raw particle material formed of an inorganic material having a D50 of not larger than 5 μm to form a granulated body; and a spherizing step of heating and melting the granulated body to form the spherical particle material having a D50 larger than a D50 of the raw particle material. A melting method is used as a basic method for manufacturing the spherical particle material having a necessary particle size distribution. The granulated body is used to manufacture the spherical particle material having the necessary particle size distribution by the melting method.

Disclosed herein are aluminum oxide aerogels and methods of making and use thereof. The methods of making the aluminum oxide aerogel include contacting a solid comprising aluminum with a Ga-based liquid alloy to dissolve at least a portion of the aluminum from the solid, thereby forming an aluminum-alloy mixture; and contacting the aluminum-alloy mixture with a fluid comprising water, thereby forming the aluminum oxide aerogel. In some examples, the methods can further comprise capturing and converting carbon dioxide to a syngas comprising carbon monoxide and hydrogen.

The present development is a reactor system for the production of nanostructures. The reactor system comprises a conical reactor body designed to maintain an upwardly directed vertical plasma flame and hydrocarbon flame. The reactor system further includes a metal powder feed that feeds into the plasma flame, a cyclone and a dust removal unit. The system is designed to produce up to 100 grams of metal oxide nanomaterials per minute.

A particulate material is mainly composed of alumina, has a volume average particle diameter of from 70 to 200 μm, has a degree of sphericity of from 0.89 or more to less than 0.99, has a degree of alfa-aluminization of from 40 to 85%, and produces a result of 0.017 g or less in an abrasion test for equipment.

The present application provides a method of fabricating a thin film transistor. The method includes selecting a nano-structure material having a monotonic relationship between a threshold voltage and a channel length when the nano-structure material is formed as a channel part in a thin film transistor; forming an active layer using the nano-structure material; determining a nominal channel length of a channel part of the thin film transistor based on the monotonic relationship and a reference threshold voltage so that the thin film transistor is formed to have a nominal threshold voltage; and forming a source electrode and a drain electrode thereby forming the channel part in the active layer having the nominal channel length.
