The dielectric polymer-based films with excellent energy storage properties have been considered as potential candidates for flexible capacitors. In this study, the hierarchical gradient structures of 0.5Ba(Zr0.2Ti0.8)O3–0.5(Ba0.7Ca0.3)TiO3 nanofibers (BZCT NFs) are designed in polyvinylidene fluoride (PVDF) composite films. different compositions BZCT NFs structure were prepared by layer-by-layer electrospinning, hot-pressing, and quenching processes. microstructures electrical studied,...
Three membrane distillation (MD) configurations, vacuum (VMD), sweeping gas (SGMD) and direct contact (DCMD), have been experimentally studied in a shell-and-tube capillary module using sodium chloride aqueous solutions as feed. The flux, fresh water conductivity desalination rate were compared. Preliminary experiments by VMD carried out seawater with the same salinity influences of operating parameters: flow rate, feed temperature, concentration, permeate vacuum, investigated. saline...
The urban heat island (UHI) is a typical environmental problem that affects people’s health and restricts development. Understanding the cooling effect of ecological landscapes residents’ perceptions can help guide planning mitigate risk. This study analyzed spatiotemporal evolution UHI in central area Xi’an City 1999, 2006, 2014, 2019, compared green space water among 13 parks 2019. Furthermore, we investigated constraining landscape patterns on perceptions. Our results show moderate...
In this work, a novel air-bubbling vacuum membrane distillation (AVMD) process was constructed on the basis of traditional (VMD) process. Compressed air pressed into lumen side hollow fiber membranes together with hot feed solution just at inlet module. So gas/liquid two-phase flow formed in lumen. Hydrophobic polyvinylidene fluoride (PVDF) microporous were employed work. The effects operating conditions, such as rate, temperature and concentration performance AVMD studied. surface...
An integrated membrane process was constructed, which composed of immersing ultrafiltration(UF) cell as pretreatment step and vacuum distillation (VMD) for both pure water reclamation from reverse osmosis (RO) drained wastewater discharge reduction. The effect feed temperature, velocity, pressure at the pump side on performance in VMD studied. concentration pretreated untreated RO compared. surface morphology hydrophobic polyvinylidene fluoride hollow fiber observed by scanning electronic...
A hollow fiber nanofiltration (NF) membrane fabricated on poly(vinyl chloride) (PVC) substrate was studied for the removal of chemicals concern (CoCs). The functional layer NF via interfacial polymerization piperazine (PIP) and trimesoyl chloride (TMC) lumen side PVC ultrafiltration membrane. gas sweeping method employed during fabrication assessed based separation performance It found that could increase membrane, which is also affected by concentration PIP TMC solutions. membranes prepared...
The polyvinylidene fluoride hollow fiber hydrophobic membrane was applied in vacuum distillation (VMD) process for the treatment of reverse osmosis-concentrated wastewater from a steel plant. effects pretreatment methods on CODcr removal, performance and fouling VMD were studied. morphology composition layer studied by scanning electron microscope energy dispersive spectroscopy, respectively. reason flux declination discussed. results showed that removal reached 40%, increased after...
Tribrachia star-shaped random copolymers with tunable thermosensitive phase transition temperature were designed and synthesized via a simple one-pot ammonolysis reaction approach trimesic acid as cores. The self-assembly micellization behavior of the in aqueous solution was examined by surface tension, UV-vis transmittance, transmission electron microscope, dynamic light scattering measurements, etc. results indicated that resultant formed micelle aggregates through hydrophobic interactions...
Hot days are one of the typical threats to human health and sustainable cities. The exploration residents' perceptions thermal environment its mitigation measures will support risk prevention. A survey with a combination closed-ended open-ended questions was conducted in July 2021 among 13 urban parks Xi'an City, China. With help ANOVA ordinal logistic regression, this study investigated influencing factors both on perception hot their effect ecological landscape reducing risk. relationship...
Electrospun nanofiber membranes show significant advantages and potential in membrane distillation (MD) technology due to their high water flux low mass transfer resistance. However, further development is limited by the unsatisfactory pore size distribution insufficient hydrophobicity that makes them prone wetting. Hence, we prepared TNPs/PDMS colloidal particles combining titanium dioxide nanoparticles (TNPs) polydimethylsiloxane (PDMS) a simple method with electrospun as support layer,...
