The invention concerns the exploitation of the process of initiating and/or accelerating and/or controlling crystallization or precipitation in supercooled melts or supersaturated solutions of solids. A problem frequently encountered with this process is that the duration of the process of solidification or crystallization cannot be precisely controlled or the process does not continue long enough to allow adequate solidification or crystallization. According to the present invention, the supercooled melt or supersaturated solution is exposed to ultrasound before being delivered to the conveyor belt in a belt system or while being discharged onto a conveyor belt, or before being delivered to a receptacle drum or while it is fed into a receptacle drum.

Принадлежит:

The movement of particles in a liquid flowing in a duct (2) is controlled by an ultrasonic standing wave having nodal fronts at a small angle to one pair of side walls of the duct. As the liquid flows along the duct, particles responsive to the acoustic energy are held on the oblique nodal fronts and are carried along these by the flow so that they also move towards one side wall (2a). Particles in the vicinity of that one side wall are swept from the nodal fronts by the liquid drag forces. At the duct exit the particles will therefore tend to be concentrated in that portion of the liquid flow that passes nearer said one wall (2a).

Номер: US20170022635A1
Принадлежит: UT Battelle LLC

A method for synthesizing silica nanofibers using sound waves is provided. The method includes providing a solution of polyvinyl pyrrolidone, adding sodium citrate and ammonium hydroxide to form a first mixture, adding a silica-based compound to the solution to form a second mixture, and sonicating the second mixture to synthesize a plurality of silica nanofibers having an average cross-sectional diameter of less than 70 nm and having a length on the order of at least several hundred microns. The method can be performed without heating or electrospinning, and instead includes less energy intensive strategies that can be scaled up to an industrial scale. The resulting nanofibers can achieve a decreased mean diameter over conventional fibers. The decreased diameter generally increases the tensile strength of the silica nanofibers, as defects and contaminations decrease with the decreasing diameter.

Принадлежит: UOP LLC

Methods and reactors are provided for producing acetylene. The method includes combusting a fuel with oxygen in a combustor to produce a carrier gas, and accelerating the carrier gas to a supersonic speed in a converging/diverging nozzle prior to the carrier gas entering a reaction zone. A nozzle exit temperature of the carrier gas is controlled from about 1,200° C. to about 2,500° C. Methane is added to the carrier gas in the reaction zone, and kinetic energy in the carrier gas is converted to thermal energy in the reaction zone to increase the temperature of the carrier gas such that the methane reacts by pyrolysis to form the acetylene. 1.
