A PVC membrane Cr(III) ion selective electrode has been constructed using 2H-1,4-benzothioazine-2,3(4H)dione dioxime (BTD) as membrane carrier. The influence of membrane composition on the electroderesponse was studied. The electrode exhibits a Nernstian response over a Cr(III) concentration range of 1.0 x10 6 to 1.0>< 10-1 M (r = 0.99) with a slope of 19.5 ± 0.5 mV per decade of concentration,...

A bio-based plasticizer, epoxidized acetylation cardanol, was synthesized from cardanol, which experienced acetylation reaction and epoxidation reaction. Chemical structure of epoxidized acetylation cardanol was characterized by FT-IR and 1H NMR. Plasticized PVC films (PVC-P) were prepared by casting method with 40%wt of epoxidized acetylation cardanol as a plasticizer. Thermal s...

In this investigation, the effects of formulation and processing factors on the adhesion between polyurethane (PU) and plasticized poly(vinyl chloride) (pPVC) layers was studied using the Taguchi method for experimental design. Among the many factors, nine parameters were screened and tested at two or three levels, taking advantage of the Taguchi L27 orthogonal array. The factors studied were P...

This work describes the construction and the evaluation of the general performance of new ampicillinate-selective electrodes based on manganese (III) tetraphenylporphyrin [Mn(III) TPP-Cl] as ionophore, incorporated in both PVC and sol-gel membranes and directly applied onto a conductive graphite/epoxy resin support. The units were constructed without inner reference solution adopting convention...

Surface modification of biomaterials is a promising approach to control biofunctionality while retaining the bulk biomaterial properties. Perlecan major proteoglycan in vascular basement membrane that supports low levels platelet adhesion but not activation. Thus, perlecan bioactive for blood-contacting applications. This study furthers mechanistic understanding interactions with by establishin...

BACKGROUND The production of vinyl chloride (VC) and polyvinyl chloride (PVC) involves the use of various chemicals, some known to be toxic and potentially or definitely carcinogenic. The related potential risk often has not been properly investigated. Updated cancer mortality among different subgroups of workers employed in a VC-PVC production plant located in Porto Marghera (Italy) was re-ana...

The mechanical stability is an important phenomenon which governs many applications based properties of membranes. The inorganic materials of membrane may have been synthesized by qualitative the novel sol-gel or co-precipitation methods of material synthesis. The mMembranes of cobalt (CP) and nickel (NP) composites have been was designed by mixing of the polyvinyl chloride (PVC) with cobalt ph...

At low temperature, the short-chain fluorescent-labeled phospholipids, 1-myristoyl-2-[6-(7-nitrobenz-2-oxa-1,3-diazol-4-yl) aminocaproyl]-phosphatidylcholine (M-C6-NBD-PC) and its phosphatidylethanolamine analog, M-C6-NBD-PE, are internalized by flip across the plasma membrane of S. cerevisiae and show similar enrichment in intracellular membranes including the mitochondria and nuclear envelope...

Membrane trafficking intermediates involved in the transport of proteins between the TGN and the lysosome-like vacuole in the yeast Saccharomyces cerevisiae can be accumulated in various vps mutants. Loss of function of Vps45p, an Sec1p-like protein required for the fusion of Golgi-derived transport vesicles with the prevacuolar/endosomal compartment (PVC), results in an accumulation of post-Go...
