Screening of foodborne pathogens is an effective way to prevent microbial food poisoning. A microfluidic biosensor was developed for rapid and sensitive detection Salmonella Typhimurium using quantum dots (QDs) as fluorescent probes sensor readout manganese dioxide nanoflowers (MnO2 NFs) QDs nanocarriers signal amplification. Prior testing, amino-modified MnO2 (MnO2-NH2 were conjugated with carboxyl-modified through EDC/NHSS method form MnO2-QD NFs, NFs functionalized polyclonal antibodies...
Summary Multilateral-horizontal-well drilling is an efficient approach for stimulating shallow, low-permeability, marginal, and coalbed-methane (CBM) reservoirs. Radial-jet-drilling (RJD) technology, which uses a high-pressure water jet, aims to drill tens of laterals from vertical wellbore. Hydraulics design essential successful field-drilling operations. However, detailed hydraulics calculations methods have not yet been published. In this study, the pressure loss, ejector force, extending...
The hydrodynamic performance of a Savonius type turbine (S-type turbine) in wave field is studied. method combining numerical simulation with physical experiment adopted.Based on linear theory and turbulence model, Star CCM+numerical software used for digital modeling, overlapping grid technology modeling. Dynamic Fluid Body Interaction (DFBI) model called to control the movement S-type turbine, second-order time discretization adopted establish two-dimensional conduct simulation. At same...
Abstract Rechargeable magnesium batteries (RMBs) are a promising energy‐storage technology with low cost and high reliability, while the lack of high‐performance cathodes is impeding development. Herein, series amorphous cobalt polyselenides (CoSe x , x>2) synthesized assistance organic amino‐terminal hyperbranched polymer (AHP) additive investigated as for RMBs. The coordination cations amino groups AHP leads to formation CoSe rather than crystalline 2 . structure favorable...
Understanding the acoustic characteristics of hydrates in various sediments is crucial for hydrate resource detection and safe efficient exploitation, as occurrence patterns vary greatly different sediments. In this work, with bentonite contents, water saturations, types were prepared to investigate P-wave velocity (reflecting magnitude saturation sediment) amplitude degree hydrate-sediment cementation) during formation depressurization. During formation, have similar trends. As clay content...
Summary A coupled computational-fluid-dynamics/discrete-element-method (CFD/DEM) theory is developed to simulate the transportation of cuttings in an inclined-slimhole annulus. In this theory, liquid phase governed by Eulerian continuum equation and Navier-Stokes momentum-conservation equation. The collisions between particle wall, drillstring, among particles are treated as spring-damping system, particle-contact model then established. particle-governing based on Newton's second law...
Modeling of hydrate growth at the interface between gas and aqueous phases is critical for evaluating rate film initial thickness in oil natural industries. However, most existing heat transfer models presumption hypothesis possess logical or physical deficiencies, which may lead to wide deviations when predicting results. In this work, a new model lateral along planar gas–liquid boundary developed, considers convection transfer. This not only correlates subcooling, generally regarded as...
A new type of spherical node was used to design a laboratory-scale prototype six-leg lattice steel tubes and concrete for application as wind turbine tower. Repeated load tests were performed on the tower several weeks evaluate its load-carrying capacity, deformation, energy consumption, stress distribution based damage patterns, hysteresis curves, skeleton strength, stiffness degradation curves. The findings indicated that underwent thread high-strength bolts inclined web weld between...
In the process of developing offshore hydrate reserves, stability subsea formations emerges as a crucial determinant, exerting significant influence on feasibility prolonged extraction. Addressing challenge seafloor subsidence induced by pressure reduction during extraction, numerical simulation method was employed that integrates multiphase seepage, heat transfer, and mechanical considerations. It delves into dynamic evolution parameters in shallow seabed formations, considering...
