Flux and antifouling properties of mixed matrix membranes (MMMs) are yet to attain satisfactory status. The objective of this study is to find a method for mitigating the biofouling of poly(ether sulfone) (PES) ultrafiltration membranes via blending of thermoexfoliated vermiculite (VMT). Flow cytometry analysis shows that the behaviors of Bacillus subtilis 168 as a Gram-positive bacterium and E...

In this study, polyvinylidene fluoride (PVDF) ultrafiltration membranes were prepared via immersion precipitation method using a mixture of two solvents triethyl phosphate (TEP) and dimethylacetamide (DMAc), which had different affinities with the nonsolvent (water). Properties of the prepared membranes were characterized using scanning electron microscope (SEM) and contact angle and membrane p...

Abstract Rapid urbanization and industrialization have created tremendous stress on fresh water sources. Moreover, discharge of industrial wastewater has left public health environment under high potential risks. In this paper, chitosan-functionalized graphene oxide (GO-CH) was synthesized incorporated into polysulfone (Psf) ultrafiltration membranes. The concentration the nanocomposite ratio G...

In this study, RuO2-embedded PES membrane was prepared and it used for protein separation. The antifouling properties of the fabricated composite membranes were also investigated using bovine serum albumin (BSA) as solution. mean roughness increased proportionally by introducing RuO2 particles. porosity higher than that pristine membrane. On other hand, has smaller average pore size after addit...

Because of the complexity, non-linearity, and under-actuated features double pendulum overhead cranes, a control method based on linear active disturbance rejection (LADRC) differential flatness theory is proposed to realize accurate trolley positioning effective swing eliminating. Specifically, in order simplify system model, we introduce construct output. Based this method, uncertainty extern...

the aim of this study was to evaluate the effect of bovine serum albomin (bsa) in stallion semen extender in cool condition. after collection, semen samples were pooled and divided into four equal parts. each part was diluted with one of the following extenders: 1) extender without bsa (bsa-0), 2) extender containing 5 mg/ml bsa (bsa-5), 3) extender containing 10 mg/ml bsa (bsa-10), and 4) exte...

Poly(ethylene glycol) (PEG) possessing a sulfobetaine (SB) moiety at one end and a pentaethylenehexamine (N6) at the other end (SB-PEG-N6) was newly synthesized as a blocking agent for immunosensing surfaces. The N6 moiety strongly coordinates on gold surfaces, facilitating the tethering of the PEG chain to the sensor chip surface, and leaves the SB moiety free. Non-specific adsorption of bovin...

Incorporation of zinc oxide (ZnO) nanoparticles has played an important role on the improvement unique membrane characterization and performance, most notably hydrophilic modification for higher pure water permeability. Additionally, permeability can be improved via introduction braid support by reducing thickness separation layer. Moreover, braided hollow fiber (BHFM) is able to perform under ...
