Halogen-substituted para-benzoquinones (p-BQs) are emerging disinfection byproducts known to induce oxidative damage both in vitro and vivo. However, as ubiquitous oxidation byproducts, the vivo toxicity transport mechanism of non-halogenated p-BQs with similar structure α, β-unsaturated ketones halogenated have not been thoroughly investigated. In this study, effect substituents on transportation 2-chloro-1,4-benzoquinone (CBQ) 2-methyl-1,4-benzoquinone (MBQ) was systematically The results...
Artificial photosynthesis for producing high-value hydrogen peroxide (H2O2) using carbon nitride-based systems holds immense potential. However, understanding the charge transfer dynamics in homojunction photocatalysts remains a significant challenge owing to limitations of current characterization techniques. Here, polymeric C3N5/C3N4 (CNHJ) is employed as model system probe interfacial electron transfer. Bimetallic cocatalysts serve sensitive probes, enabling situ tracking S-scheme between...
Machining accuracy of a machine tool is influenced by geometric errors produced each part and component. Different have varying influence on the machining tool. The aim this study to optimize get desired performance for numerical control Applying multi-body system theory, volumetric error model was constructed track compensate effects during operation machine, relate functional specifications permissible joints links machine. Error sensitivity analysis used identify different (especially...
With the development of industrial manufacturing, flexible manufacturing system provides an effective way to improve machining quality and efficiency, as well reduce cost. Fflexible reliability has been one focus recent studies. But a systematic, executable evaluation method not yet proposed in existing researches. This work firstly presented three-layer index for evaluation, which is composed whole layer indexes, subsystem indexes equipment determined by composition running features...
The energy consumption loss is high particularly in manufacturing processes involving heating furnaces. Moreover, the mandatory constraints continuous stage bring difficult challenges to production scheduling. To improve efficiency and reduce a hybrid flow shop with discrete processing stages, this study developed an adaptive selection multi-objective optimization algorithm preference (ASMOAP). of are transformed into one objectives, which defined as maximum excess value adjustment time...
This paper aims to solve the problem of high energy consumption in forging production through energy-saving scheduling. By analyzing flow shop characteristics a workshop, an energy-efficient hybrid scheduling with tempering (EEHFSP-FT) is proposed. An model established simultaneously minimize both completion time and consumption. In model, constraints such as heating furnace capacity, required temperature, quenching temperature are taken into consideration. strategy heat treatment residual...
Ball screw mechanisms (BSMs) are used as accuracy transmission components in a wide range of industries and characterized by their high accuracy. More specifically, the positioning BSM has significant effect on machine tool. Based macro-micro multiscale method, an exponential prediction model for was developed considering time-varying working conditions (load rotational speed) feed modes. Since degradation is mainly caused wear, microscopic approach proposed to describe retention wear...
Abstract Hydrophilic polymer coatings can improve the surface characteristics of artificial implants. However, because they are used in vivo, inevitably come into contact with biomolecules that affect their interfacial tribological properties. In this paper, friction behaviors poly(vinylphosphonic acid) (PVPA)-modified Ti6Al4V and polytetrafluorethylene balls were analyzed using albumin, globulin, aggrecan, hyaluronic acid as lubricants. The interaction properties dynamic adsorption PVPA...
This study aims to analyze the impact of uniform and eccentric load conditions on performance internal feedback hydrostatic thrust journal bearing. Two distinct models are established: a three-degrees-of-freedom model five-degrees-of-freedom model. The support stiffness, overturning flow rate for both bearings calculated. Additionally, numerical analysis is conducted examine influence oil film thickness, inlet pressure, restrictor size operational characteristics bearings, revealing...
The stability of the tribological properties polymer coatings is vital to ensure their long term use. superlubricity poly(vinylphosphonic acid) (PVPA)-modified Ti6Al4V/polytetrafluoroethylene (PTFE) interface can be obtained when lubricated by phosphate-buffered saline (PBS, pH = 7.2), but not deionized water and ethanol. Therefore, mechanisms for PVPA affected lubricant were investigated in detail. compatibility with are critical factors realizing ideal coatings. Robust stable under a wide...
