Abstract Superconducting cavity electro-optics presents a promising route to coherently convert microwave and optical photons distribute quantum entanglement between superconducting circuits over long-distance. Strong Pockels nonlinearity high-performance are the prerequisites for high conversion efficiency. Thin-film lithium niobate (TFLN) offers these desired characteristics. Despite signific...

A fully controllable nano-electro-mechanical device that can pump fluids at nanoscale is proposed. Using molecular dynamics simulations, we show that an applied electric field to an ion@C60 inside a water-filled carbon nanotube can pump water with excellent efficiency. The key physical mechanism governing the fluid pumping is the conversion of electrical energy into hydrodynamic flow with effic...

A high-pressure electro-osmotic (EO) micro-pump fabricated by a sol–gel process is shown to be potentially effective as a fluid-driving unit on chip-scale analytical systems. A silica monolithic matrix with a morphology of micron-scaled through pores was synthesized within the 100 m inner diameter (i.d.) fused-silica capillary of the micro-pump. The monolith bonds directly with the capillary wa...

The electro-osmotic flow driven by a screen pump, composed of a line array of evenly spaced identical rectangular solid blocks, is investigated under the Debye-Hückel approximation. The geometry of the screen pump is determined by the spacing and aspect ratio of the solid blocks. A constant surface zeta potential is assumed on the block surface. The method of eigenfunction series expansion is a...

Pumps are often used in both industrial applications and mobile hydraulic machinery. In variable displacement pumps, the flow rate is dictated by the system requirements. The electro-hydraulic pump is a new integrated product, which comprise the combination of a pump and motor as a unit replacing the traditional connection with a shaft coupling. The pump is actuated without a rotating shaft uti...

this paper presents a fuzzy search controller approach along with the look-up tables, to optimize the efficiency of a pump-induction motor drive. the induction motor and the converter are modeled based on thermal loss; and for modeling the pump and the hydraulic system, which are non-linear and relatively complicated, the neural network is used. in the designed system, in order to optimize the ...

Abstract Electro-optically Q-switched side-pumped diode-pumped KTP/YAG:Nd 3+ nanosecond laser system with an intracavity collinear optical parametric oscillation was proposed as a pump source for Cr 2+ :ZnSe laser. Energy parameters of were investigated respect to the wavelength Under optimal conditions, pumping pulses energy 10.5 mJ and duration 7.2 ns at 1950 nm allowed obtain 3.2 2494 slope ...

pressurized irrigation is a recent development that consumes more energy for the pressure produced. in thisstudy, energy consumption, waste and efficiency were investigated at a diesel and electrical sprinklerirrigation pumping plant in some fields in hamadan province during 2007-8. nebraska performance criteria(npc) were used to compare sprinkler irrigation pumping plant performance. the resul...

liquid membrane processes have attracted many interests in recent years for removal of heavy metals such as cadmium from industrial wastewaters. in this study, a modified hybrid liquid membrane system is introduced. the setup is worked by applying the water-insoluble dioctyl phthalate as the organic solvent. n-octanol and tetra butyl ammonium bromide are added to the organic phase to increase t...

A high-pressure electro-osmotic micro-pump fabricated by a sol-gel process is reported as a fluid-driving unit in a flow-injection analysis (FIA) system. The micro FIA system consists of a monolithic micro-pump on a glass slide (2.5 x 7.5 cm), a micro-injector, and a micro-sensor (2.5 x 1.5 cm). The monolithic silica matrix has a continuous skeleton morphology with micrometer-sized through-pore...
