Exposure of therapeutic and diagnostic medical devices to biological fluids is often accompanied by interfacial adsorption of proteins, cells, and microorganisms. Biofouling of surfaces can lead to compromised device performance or increased cost and in some cases may be life-threatening to the patient. Although numerous antifouling polymer coatings have enjoyed short-term success in preventing...

The type and loading level of oxygen-containing functional groups on graphene oxide (GO) nanosheets significantly affect the size alignment nanochannels formed between GO separation performance laminar membranes. Here, we demonstrate how double-oxidation leads to higher surface charge nanosheets, formation highly stable water-based solution, more-ordered deposition GOs polyethersulfone membrane...

Nanofibrous ultrafilter of nylon6.12/chitosan@Poly ether sulfone (N6.12/CS@PES) membrane were fabricated by chitosan casted PES and coated with nylon6.12 thin layer using electrospinning technique for dye rejection. The membranes characterized scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD). capacity the to reject both cationic anioni...

?2 microglobulin (?2m) fibril has been recognized as the major factor of dialysis-related amyloidosis. elevated serum levels are thought to be the basis for tissue deposition. in order to evaluate the effect of cellulosis membrane (fb 110) and treatment duration on s?2m levels, we determined serum levels in 23 hemodialyzed patients with end-stage renal failure. s?2m levels were markedly elevate...

Polyvinylidene fluoride (PVDF)/g-C3N4/Chitosan thin film membranes were prepared by immersing of PVDF/g-C3N4 membrane in solution containing various concentrations chitosan for removal Direct Blue 14 dye (an anionic dye) from aqueous solutions. The resulting characterized XRD, FESEM, TEM and AFM. Also, pure water flux, salt rejection, content antifouling properties investigated. demonstrate tha...

Abstract These days, sensors are widely used in a variety of underwater sites like marine monitoring, fish-farming and water quality monitoring. However, to achieve reliable sensor data from long-term monitoring aqueous solution, several challenges still need be solved. Biofilm formation both on housings membranes is among one the most serious challenges, which strongly influences responds vali...

The scarcity of freshwater is one the major challenges to civilized community around World. So, various engineered processes have been developed for remediation this problem such as osmotic pressure-driven (OPDPs). OPDPs includes forward osmosis and pressure retarded osmosis, which gained enormous attention becoming a flexible membrane-based technology desalination wastewater treatment. most si...

Many desalination plants still struggle to control biological fouling in seawater reverse osmosis (SWRO) systems as there are no standard methods monitor this type of fouling. Strategies biofouling SWRO have been proposed such antifouling coating and lowering potential feedwater through pretreatment processes. Measuring the has gained increased interest due its direct link biofouling. Moreover,...
