The abilities of various sorbent materials for heavy metal removal have been reported in the literature. We have developed a novel approach to obtain high metal-sorption capacity utilizing a membrane containing 2-methacrylamidophenylalanine. Metal-complexing ligand 2-methacrylamidophenylalanine (MAPA) was synthesized through the use methacrylo chloride

Abstract Magnetic nanoparticles (Fe3O4) coated with polyethylene glycol (PEG), (Fe3O4/PEG), were synthesized by chemical co-precipitation of Fe2+/Fe3+ salts by aqueous ammonia in PEG solution. Radiation polymerization of 2-hydroxyethyl methacrylate (HEMA) monomer solution onto Fe3O4/PEG was performed at different doses to synthesize (Fe3O4/PEG)-pHEMA,

A small diameter cardiovascular prosthesis was developed that utilized compound coatings of a stable, three-dimensional, fluid-imbibing gel network having controlled and identified microstructure. Two types of polyethylene terephthalate (Dacron('(REGTM))) tubular substrates (USCI('(REGTM)) DeBakey('(REGTM)) Vasculour('(REGTM))-D and USCI('(REGTM ...

In the experiments on rabbits histological specimens with embolus radiopaque by iodides, bromides of silver and by (3-amino-2,4,6-triiodobenzyl) oil acid have been investigated 7 days after implantation. Optimum emboli were used in clinical practice during preoperative procedure for endovascular occlusion of liver and kidney arteries.

The nanofiber membranes based on native starch are prone to swelling or dissolution after contact with water, and the fragile starch membranes, due to the aging of molecular chains, are unsuitable for medical dressings. Herein, the hydrophobic polyhydroxyethyl methacrylate (PHEMA) branches in different ratios were grafted onto high amylose corn starch (

Two types of polyethylene terephthalate (Dacron) substrates (USCI DeBakey Vasculour-D and USCI Sauvage filamentous) have been selectively coated with Poly-hydroxyethyl methacrylate (P-HEMA) in a two-stage process. Using scanning electon microscopy (SEM) techniques, the microstructural details of the fabrications were identified. The first stage of this

The study analyses the possibility of using polyhydroxyethyl methacrylate as a material for the slow release of antibiotic in periodontal pockets. The antibiotics examined were tetracycline and metronidazole. The aim of the study was to evaluate the biocompatibility of the material with periodontal tissue and the efficacy of the 2 prepared systems. Two
