The objective of this research was to evaluate a select number of promising surface treatments for making ceramic membranes hydrophobic and suitable for application in direct contact membrane distillation (DCMD). Alumina anodiscTM membranes were made hydrophobic through surface treatments that utilized perfluorodecyltriethoxysilane, trimethylchlorosilane, or trichloromethylsilane. The effective...

14 The objective of this study was to develop a new measurement technique for the determination of pore size distributions (PSDs) of polymeric and ceramic membranes, including NF, UF, and MF membranes. The proposed method uses the fractional rejection (FR) concept of a solute in membrane pores. Experimental measurements were conducted using a high performance liquid chromatography (HPLC) equipp...

Salinity gradient energy (SGE) refers to the energy created from the difference in salt concentration between two streams. There are three types of SGE namely, pressure retarded osmosis (PRO), reverse electrodialysis (RED), and capacitive mixing (CapMix). All these technologies require membrane for the system to be operational. In this short review, the membranes modifications for each principl...

Membrane technology provides advantages for separating and purifying food materials, including juice clarification. Ultrafiltration processes fruit juices aim to remove haze components maintain the stabilization of juices. However, membrane process during clarification suffers from fouling, which deteriorates performance products. Biofouling usually is found in applications processing. In this ...

In this work, the performance of organic pollutant removal, membrane fouling and sludge morphology in a submerged membrane bioreactor (MBR) treating sunflower oil refinery wastewater (SORW) containing high oleic content was studied during 52 days’ operation at short values of 18 h and 10 days for hydraulic retention time and sludge retention time, respectively. The removal efficiencies of chemi...

The potential of integration of functions in microfluidic chips is demonstrated by implementing on-chip preconcentration of proteins prior to on-chip protein sizing by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE). Two polymeric elements-a thin (approximately 50 microm) size exclusion membrane for preconcentration and a longer (approximately cm) porous monolith for protei...

This article presents different types of commercially available roof waterproofing membrane systems used on roofs with large surface area. It deals the causes deterioration such membranes due to environmental factors and describes tests detect leaks determination severity polymeric taking into account properties declared by their manufactures. The last part is a case study comparing brand new a...

Amphotericin B (AmB) preloaded polymeric cores cloaked with vaginal epithelial cells membrane (VM-ANP) are capable of localizing to the sites Candida albicans infection. Upon such strong adhesion, retention, and penetration, VM-ANP shows a controlled release AmB; thus, enhancing fungal killing reach its full potential. This is reported by Mengchun Chen, Ledan Wang, Yijie co-workers in article n...

The rapid and active transport of polymeric IgA from the blood to the bile (1, 2) is selective (3, 4), which suggests the existence of a specific receptor for this molecule. The liver cells responsible for the transfer have been identified as the hepatocytes by autoradiography and electron microscopy of the livers o f rats killed 5, 30, and 60 min after the injection of radiolabeled IgA (5). 5 ...
