A microfluidic chip that integrates all the fluidic components of a gradient liquid chromatography (LC) system is described. These chips were batch-fabricated on silicon wafer using photolithographic processes and with Parylene as main structural material. The fabricated includes three electrolysis-based electrochemical pumps, one for loading sample other two delivering solvent gradient; platinum electrodes current to pumps establishing electrospray potential; low-volume static mixer; column...
An electrostatically actuated micro peristaltic pump is reported. The entirely surface micromachined using a multilayer parylene technology. Taking advantage of the technology, design enables pumped fluid to be isolated from electric field. Electrostatic actuation membrane both DC and AC voltages was demonstrated applied pumping based on 3-phase sequence. A maximum flow rate 1.7 nL min−1 an estimated pressure 1.6 kPa were achieved at 20 Hz phase frequency. dynamic analysis also performed...
Thermoelectric (TE) hydrogels, mimicking human skin, possessing temperature and strain sensing capabilities, are well-suited for human-machine interaction interfaces wearable devices. In this study, a TE hydrogel with high toughness responsiveness was created using the Hofmeister effect current effect, achieved through cross-linking of PVA/PAA/carboxymethyl cellulose triple networks. The facilitated by Na
Within the context of microfluidic systems, it has been difficult to devise pumping systems that can deliver adequate flow rates at high pressure for applications such as HPLC. An on-chip electrochemical system based on electrolysis offers certain advantages over designs utilize electroosmotic driven fabricated and tested. The pump was both silicon glass substrates using photolithography. electrodes were formed from either platinum or gold, SU8, an epoxy-based photoresist, used form...
Abstract The flashover and dampness on the surface of epoxy resin (ER) composites are two critical factors leading to failure high voltage direct current (HVDC) insulating devices. Designing constructing a structure with hydrophobic performance is an effective way solve these problems. In this paper, we prepared fluorinated silica nanoparticles (F‐SiO 2 ) using combination dielectric barrier discharge (DBD) plasma 1H,1H,2H,2H‐Perfluorodecyltrimethoxysilane (FAS‐17). resulting...
This paper presents lumped-parameter simulation of dynamic characteristics peristaltic micropumps. The pump consists three pumping cells connected in series, each which is equipped with a compliant diaphragm that electrostatically actuated sequence to mobilize the fluid. Diaphragm motion cell first represented by an effective spring subjected hydrodynamic and electrostatic forces. These representations are then used construct system-level model for entire pump, accounts both cell- pump-level...
Bismuth ferrite nano‐ and microcrystals were prepared by a facile molten salt technique in two kinds of molten‐salt‐based systems ( NaCl – KCl Na 2 SO 4 ). In the system, systematic study indicating effects process parameters (e.g., calcination temperature, holding time as well ratios) on bismuth formation mechanism structural characteristics is reported. The results show that almost pure phase BiFeO 3 powders with minimum impurity Bi Fe O 9 synthesized at temperatures 700°C–800°C, whereas...
With the increasing demands for higher treatment efficiency, better effluent quality, and energy conservation in Urban Wastewater Treatment Plants (WWTPs), research has already been conducted to construct an optimized control system Anaerobic-Anoxic-Oxic (AAO) process using a data-driven approach. However, existing optimization systems AAO mainly focus on improving water quality reducing consumption, therefore they lack consideration stability of bioreactors. Meanwhile, safety is still...
Coal mine gas control has always been the focus of coal mining enterprises. Curing seam prevention and disaster technology is a new type local management to achieve rapid excavation. The key lies in changing generation conditions hydrate so that it can solidify reduce pressure seam. This paper measured contact angle four kinds thermodynamic accelerators on body, HCFC-141b was screened as by combining their own physical chemical properties. SDS-R141b compounding system used investigate its...
This paper combines simulation and experiment to construct a transient field model for gas-solid composite insulation. Nonlinear gas conductivity, which is constructed by ion transport, with material intrinsic surface conduction explore the electrical properties of epoxy resin (EP) under step gradient conductivity (SGSC). SGSC controls maximum charge density at triple junction, reduces total charge, alleviates strength, homogenizes electric distribution, suppresses power losses caused...
