Purpose: To prepare polystyrene nanofiber ion exchangers (PSNIE) with surface cation exchange functionality using a new method based on electrospinning and also to optimize crosslinking and sulfonation reactions to obtain PSNIE with maximum ion exchange capacity (IEC). Method: The nanofibers were prepared from 15% w/v polystyrene solution in dimethylacetamide (DMAc) containing 0.025 %w/v tetrab...

The olefin separation from their mixture with paraffins by facilitated transport membranes is a very important process for the further macromolecular compounds production. Membranes loaded silver ions, which are responsible transport, instable time due to reduction, while those containing protons catalyze polymerization of olefins. In this work, based on polyethylene grafted sulfonated polystyr...

The ability of cancer cells to invade neighboring tissues is crucial for cell dissemination and tumor metastasis. It is generally assumed that cell adhesion to extracellular matrix proteins is an important stage of cancer progression. Hence, adhesion of cancer cells under in vitro conditions to proteins adsorbed on a substratum surface has been studied to provide a better understanding of cell-...

Nowadays, aquatic pollution is one of the most important global challenges, due to discharges a wide variety various hazardous materials from different activities which have significant environmental, economic and healthy impacts. Industries related organic dyes onsume large amounts water contribute significantly growing problem pollution. The current study describes conversion plant wastes int...

The high-molecular-weight sulfated or sulfonated polysaccharides or polymers cellulose sulfate, dextran sulfate, and polystyrene sulfonate were tested for microbicidal activity against bovine papillomavirus type 1 (BPV-1) and human papillomavirus type 11 (HPV-11) and type 40 (HPV-40). In vitro assays included the BPV-1-induced focus-forming assay and transient infection of human A431 cells with...

The author has focused on the corrosive effect of 0.14% carbon steel in occurrence several amounts soluble Sulfonated Polystyrene (SPS) and was found to be best efficient soft iron exterior at 100ppm concentration 0.5M hydrochloric acid assortment 298K heat during 3h time this paper. examination performed by studying weight loss mild varying different parameters like mixture concentration, time...
