Electrospun membranes are gaining interest for use in membrane distillation (MD) due to their high porosity and interconnected pore structure; however, they are still susceptible to wetting during MD operation because of their relatively low liquid entry pressure (LEP). In this study, post-treatment had been applied to improve the LEP, as well as its permeation and salt rejection efficiency. Th...

Neurofilaments (NFs) are a major constituent of nerve cell axons that assemble from three subunit proteins of low (NF-L), medium (NF-M), and high (NF-H) molecular weight into a 10 nm diameter rod with radiating sidearms to form a bottle-brush-like structure. Here, we reassemble NFs in vitro from varying weight ratios of the subunit proteins, purified from bovine spinal cord, to form homopolymer...

In the present paper we present an experimental investigation of the onset and detachment of leading edge cavitation. Tests are conducted in the LMH high speed cavitation tunnel on a 2-D Naca0009 hydrofoil having 100 mm chord length. Both Particle Image Velocimetry and flow visualisation are conducted for different test conditions. At low incidence angles, in the case of non cavitating flow, th...

Batch RO is designed to achieve high energy efficiency and recovery in desalination. However, so far relatively few experiments on batch have been reported. Here we present an extensive experimental study of a single-acting, free-piston system using 8-inch spiral wound membrane. The was tested the laboratory with brackish feed water containing up 5 g/L NaCl. objective quantify performance terms...

Nanofiltration (NF) with high water flux and precise separation performance Li+/Mg2+ selectivity is ideal for lithium brine recovery. However, conventional polyamide-based commercial NF membranes are ineffective in recovery processes due to their undesired selectivity. In addition, they constrained by the permeance trade-off, which means that a highly permeable membrane often has lower this stu...

This work presents poly(terephthalic-co-glycerol-g-fumaric acid) (TGF) as a novel water-soluble polymeric nano-additive for the modification of polyethersulfone ultrafiltration membrane. The TGF was harnessed pore former, aiming to improve membrane surface porosity and hydrophilicity. Modified membranes were characterized observe influence varying content on their hydrophilicity, porosity, morp...

There is a large amount of oil-contaminated wastewater caused by oil/gas production and marine oil spills. It still major challenge for the development oil/water separating membranes that have excellent separation efficiency, can withstand saline environments, long-term durability. We present new membrane made ultralong titanate nanofibers (TNF) (with diameter 200 nm length 60 µm) carbon (CNF) ...

Carbon nanotubes (CNTs) with hollow nanochannels have attracted much attention in preparing high-performance water treatment membranes. In this paper, the grafting polymer chains, including alkynyl terminated poly(methyl methacrylate) methacrylate (PMMA) single chain and PMMA-b-poly (ethylene glycol) [P(PEGMA)] diblock molecular were synthesized by reversible addition-fragmentation transfer (RA...

The anaerobic osmotic membrane bioreactor (AnOMBR) system was evaluated for the treatment of high-strength synthetic textile wastewater. chemical oxygen demand (COD) concentration above 3,000 mg/L and color 1,300 Pt-Co in study divided into six cycles roughly nine days each. Mono ammonium phosphate with 1 M used as draw solution. Average COD removal efficiencies from were 57% ± 5% 43.7% 6%, res...

BACKGROUND Necrotic enteritis (NE) is an economically important disease of poultry caused by certain Clostridium perfringens type A strains. The NetB toxin plays a critical role in the pathogenesis of NE. We previously demonstrated that netB is located within a 42 kb plasmid-encoded pathogenicity locus (NELoc-1), which also encodes 36 additional genes. Although NetB clearly plays a role in path...
