Optimum hydrothermal synthesis conditions of carbon fixing mineral-dawsonite

This paper summarizes specific features of supercritical hydrothermal synthesis of metal oxide particles. Supercritical water allows control of the crystal phase, morphology, and particle size since the solvent's properties, such as density of water, can be varied with temperature and pressure, both of which can affect the supersaturation and nucleation. In this review, we describe the advantages of fine particle formation using supercritical water and describe which future tasks need to be solved.

Fast least-squares reverse time migration based on cycle-consistent generative adversarial network

Reverse-time migration of multiples can generate imaging results with wider illumination, higher folds, and broader wavenumber spectra than the conventional migration of primaries. However, the results of the migration of multiples retain heavy crosstalks generated by interactions between unrelated multiples, thereby seriously degrading imaging qualities. To eliminate such crosstalks, we propose a least-squares optimized algorithm of multiples. In this method, different-order water-column multiples and water-bottom-related multiples are extracted using multiple decomposition strategies befo

Reaction kinetics of sodium nitrite and ammonium chloride system considering conversion rate

Aiming at the problem that the existing NaNO 2 /NH 4 Cl reaction kinetic equation that does not consider the conversion rate of reactants is difficult to effectively predict the heat/nitrogen generation situation, the experimental test analysis method is used to explore the H + concentration limit and reaction conversion rate of nitrogen generation reaction. The gray relational analysis method was used to study the influence degree of each factor; the Newton-Raphson iterative method was used to calculate the reaction kinetic parameters of the reaction conversion rate, and the prediction met

Mechanism on interaction between charged particles and wax crystals of waxy oils under high-voltage electric field

High-voltage electric field-driven jet deposition technology is a novel high resolution micro scale 3D printing method. In this paper, a novel micro 3D printing method is proposed to fabricate wax micro-structures. The mechanism of the Taylor cone generation and droplet eject deposition was analyzed, and a high-voltage electric field-driven jet printing experimental system was developed based on the principle of forming. The effects of process parameters, such as pulse voltages, gas pressures, pulse width, pulse frequency, and movement velocity, on wax printing were investigated. The experi

Optimal design of submersible permanent magnet synchronous motor with double-assisted permanent magnet Halbach array based on SVM

The harmonics and fundamental amplitude of air gap flux density will directly affect the performance of the oil-submerged permanent magnet synchronous motor. To analyze and optimize the air gap magnetic density of this motor, a surface oil-submerged permanent magnet synch ronous motor with double auxiliary permanent magnet Halbach array structures was designed and optimized. The permanent magnets of the motor was magnetized by the Halbach method. The magnetizing direction of the main magnet is the radial magnetizing, and the magnetizing directions of the double auxiliary magnets are the par
