Abstract: A method of strengthening through real-time coupling of electrical pulses and laser shock waves is provided. The initial time and duration of the electrical pulses are controlled to be matched with the initial time and duration of the laser shock waves, so that the electrical pulses and the laser shock waves are coupled in real time for material strengthening, the plasticity and the strength of the material are greatly improved, and a large area of the workpiece is uniformly strengthened. By simultaneously introducing the electrical pulses into the pulse current-assisted LSP, a great strengthening effect is achieved through the combination of the electrical pulses and the pulse current-assisted LSP in a short time, thereby reducing the internal defects of the material to a certain extent and further increasing the fatigue life of the material.

The present invention accurately determines and identifies a shallow soil landslide in a quantitative manner, improving the early identification efficiency of a landslide and helping to improve the disaster prevention effect.

Abstract: This is an early warning method for a shallow soil landslide based on a digital topographic map, belonging to the field of landslide prevention and control engineering. It has following steps: a. connecting a straight line along an upward bulged intermediate point of a contour line of the topographic map as an intermediate line; b. determining an intermediate point; c. constituting a three-point group of a plane curvature; d. taking an arithmetic average of slopes as a slope ? of a landslide mass. The shallow soil landslide can be early warned without a lot of historical observation data of landslide occurrence, and the dangerous landslide mass can be determined in advance, which greatly improves the applicability of disaster prevention and the early warning efficiency.

Abstract: The present invention is directed to a multiplexed system for electrospraying cooling fluid to produce electrically charged droplets essentially uniform in size for cooling applications. The system comprise a preferably microfabricated fluid distributor consisting of multiple nozzles/atomizers from which the droplets are dispersed, an extractor electrode consisting in an electrically conductive plate with multiple holes coaxial with the nozzles and a third electrode consisting of either the surface to be cooled or another conductive material in contact with said surface. The system provides highly efficient cooling by avoiding the droplet rebound, when the charged droplets are pinned on the surface to be cooled by the electric image force. Testing of a prototype system demonstrated a heat flux removal of 96 W/cm2 with a remarkable cooling efficiency reaching 97%.

Abstract: A particle generation apparatus and a particle generation method each employ: (1) a nozzle from which exits a liquid micro-jet stream; and (2) a ground electrode separated from the nozzle, where both the nozzle and the ground plane are DC voltage biased when operating the nozzle. Each of the particle generating apparatus and the particle generating method also employ a pair of AC electrodes interposed between the nozzle and the ground electrode and perpendicular to the liquid micro-jet stream. When a liquid supply is supplied to the nozzle, a DC voltage bias is supplied to the nozzle and the ground electrode, and an AC voltage bias and AC frequency bias is applied to the pair of AC electrodes a liquid particle spray is generated by the apparatus and the method. With additional parametric adjustment, the liquid particle spray may be monodisperse and bifurcated.

Abstract: A multiplexed emitter source distributor electrode, a related multiplexed electrospray nozzle, a related multiplexed electrospray apparatus and a related coating method that uses the multiplexed electrospray apparatus are all predicated upon at least one of: (1) a linear emitter source density greater than about 15 emitter sources per centimeter; and (2) an area emitter source density greater than about 225 emitter sources per square centimeter. The distributor electrode comprises other than a silicon material (i.e., a metal, metal alloy, ceramic or polymer material). The distributor electrode may be fabricated using a computerized numerical control method that provides the coating method with enhanced uniformity. The nozzle and the apparatus may also use a stepped slotted extractor electrode.
