摘要:
The present invention refers to a method of manufacturing layered metal oxide particles, the method comprising: placing a metal electrode in an electrolyte; and applying an electrical voltage to the electrode, wherein the metal electrode forms the anode, to form a metal oxide layer on the electrode surface, wherein the electrical voltage applied is higher than the breakdown voltage of the metal oxide, thereby breaking down the metal oxide layer formed on the electrode surface into metal oxide particles that react with the electrolyte to form the layered metal oxide particles. The present invention also refers to a layered metal oxide particle obtained from the method, and a method of manufacturing a crystalline metal oxide nanosheet or a crystalline metal oxide nanoribbon.

摘要:
Porous ceramic catalyst supports or filters to be provided with catalyst coatings via oxide washcoating processes are pre-coated with polymer barrier layers to prevent washcoat nanoparticle intrusion into the microcracked and/or microporous surfaces of the ceramics, the barrier coatings being formed of hydrocarbon polymers that are soluble or dispersible in polar media, capable of forming neutral or hydrophilic surfaces on porous ceramic supports, and completely vaporizable at moderate washcoat stabilization or catalyst activation temperatures.

A method for drilling a well along a planned trajectory includes: receiving downhole data from a steerable drilling tool; processing the downhole data and creating a downlink path, the downlink path being recognizable by the steerable drilling tool; and controlling the trajectory of the steerable drilling tool based on the downlink path.

摘要:
Porous ceramic articles may be produced by using a gas as a pore former, where the gas is injected into a ceramic precursor batch material and mixed. Pressure is then applied to mixture such that the gas liquefies. The pressure is maintained during formation of a green body, maintaining the gas in a liquefied state. After formation of the green body, the pressure is removed whereby the gas returns to a gaseous state, creating pores in the green body. The green body may then be fired to produce a porous ceramic article.
