Abstract In the present work, we developed a hybrid membrane via phase inversion process composed from polysulfone (PSF), cellulose nanocrystals (CNCs), and polyaniline (PANI) polymers for oil/water separation. Multiple techniques were used to characterize membranes. Results demonstrated that under gravity-driven process, blended PSF with CNC PANI had greatly higher water flux of 31.10, 29.01 2...

Matsu To reduce membrane fouling of reverse osmosis (RO) membrane, we adopted layer-by-layer (LbL) assembly. LbL assembly has received attention as a means of preparing ultrathin layers of composite membrane...

Separation of cyanide, as a model contaminant, from aqueous solution was investigated using molecular dynamics simulations. In this research, cyanide separation was investigated using armchair silicon carbide (SiC) nanotubes of four different diameters at different applied pressures. The systems included (5,5), (6,6), (7,7) and (8,8) SiC nanotubes placed between two graphene sheets, and an exte...

   In this study, linearized transport pore model (LTPM) is applied for modeling nanofiltration (NF) membrane separation process. This modeling approach is based on the modified extended Nernst-Planck equation enhanced by Debye-Huckel theory to take into account the variations of activity coefficient especially at high salt concentrations. Rejection of single-salt (NaCl) electrolyte is inve...

background: the innate immunity plays an important role in the host response to transplantation by toll-like receptors and results in development of acute allograft rejection. the aim of this study was to evaluate the association of tlr2 and cd14 (co-receptor) gene polymorphisms with acute rejection in kidney transplant recipients.   methods : the study was conducted in a population of 239 subj...

BACKGROUND Microsurgical lung transplantation in rats has allowed us to obtain new knowledge about lung transplantation. However, some aspects in human transplantation technique still have not been included in this model, which could interfere with the clinical interpretation and extrapolation of results. METHODS Twenty left lung transplantations were performed with a cuff technique and techn...

In this paper, vertically aligned carbon nanotube (VACNT) membranes of different densities are developed and their performances are investigated. VACNT arrays of densities 5 × 10(9), 10(10), 5 × 10(10) and 10(11) tubes cm(-2), are initially grown on 1 cm × 1 cm silicon substrates using chemical vapour deposition. A VACNT membrane is realised by attaching a 300 μm-thick 1 cm × 1 cm VACNT array o...

Mycophenolic acid (MPA) is prescribed to prevent allograft rejection in organ transplanted patients. However, its use is sporadically linked to leak flux diarrhea and other gastrointestinal (GI) disturbances in around 75% of patients through yet unknown mechanisms. Recently, we identified Midkine as a modulator of tight junctions (TJs) permeability in MPA treated Caco-2 monolayer. In the presen...

Advancing the design of thin-film composite membrane surfaces is one of the most promising pathways to deal with treating varying water qualities and increase their long-term stability and permeability. Although plasma technologies have been explored for surface modification of bulk micro and ultrafiltration membrane materials, the modification of thin film composite membranes is yet to be syst...

Composite membranes with nano-sized inorganic materials have high selectivity, hydrophilicity, and improved fouling resistance. Blending Carbon Nanotubes (CNTs) in the polymer solution improves membrane properties like water permeability, The effect of amount, together CNT amount on properties, was investigated this work. There more than 10% increase hydrophilicity 1% addition, but it not alter...
