In this work, polyvinylchloride (PVC) membrane prepared via casting solution technique and phase inversion method. N, N dimethylacetamide (DMAC) was used as primary solvent and Tetrahydrofuran (THF) was used as a co-solvent. The effects of parameters such as membrane thickness, evaporation time of casting film before immersion precipitation and addition of polyethylenglchol (PEG) on PVC membran...
Plasticized polyvinylchloride film has been used in this burns unit for a long time for dressings before the ward round, before surgery, and when the burned patient is transferred from the casualty department to the burns unit. Plasticized polyvinylchloride film is easy to use, safe, and causes no pain. Most importantly, in the present financial climate, it is cheap.
In this research, polyvinylchloride based composite heterogeneous cation exchange membranes were prepared by the solution casting technique. Chitosan-co-iron nickel oxide nanoparticles were utilized as membrane surface modifier to improve the membranes electrochemical properties. The effect of additive nanoparticle concentration in the modifier solution on the properties of composite membranes ...
This work presents a flexible miniaturized ion-selective sensor consisting of a solidcontact reference electrode (RE) and ion-selective electrodes (ISE) fabricated on the same foil. The flexible ion sensor was based on AgCl electrodes screen printed on polyethylene terephthalate foil. The RE was formed by casting a mixture of plasticized polyvinylchloride (PVC) and KCl on the AgCl electrode. Th...
Scanning electron microscopy was used to assess the morphological features of coagulase-negative staphylococci adherent to polyvinylchloride intravascular catheter specimens. Clinical specimens were obtained by using patient catheters from which coagulase-negative staphylococci (greater than or equal to 15 colonies per catheter) grew on semiquantitative blood agar roll cultures. In vitro specim...
