Different plastics recovered from a local urban solid waste plant were collected before landfilling, separated, and classified by families, i.e. polyethylene (PE), polypropylene (PP), high impact expanded polystyrene (HIPS EPS, respectively), terephthalate (PET), polyvinyl chloride (PVC). A systematic pyrolysis study was carried out to compare the different behavior registered in each plastic t...

OBJECTIVE Microwave warming of intravenous crystalloid solutions is an accepted practice in operating suites and emergency departments. These intravenous solutions are stored in polyvinyl chloride (PVC) and are known to be acidic. Some of this acidity may be from PVC packaging. We asked if microwave heating affected the acidity of 0.9% saline solution in 1 litre and 100 mL PVC bags. METHODS S...

The biosynthetic thermoplastic poly-4-hydroxybutyrate (P4HB) possesses favorable tensile strength and elongation performance and has been studied as a new implantable polymer material for medical uses. However, its hemocompatibility has not been tested to confirm its applicability to tissue engineering. In this study, a series of experiments was performed that included erythrocyte hemolysis tes...

Abstract Polymeric blends and nanocomposites with improved functional properties have attracted attention worldwide for industrial applications. For food packaging applications carrying purposes, the materials to be used should UV blocking ability, antibacterial activity, good mechanical properties. In this study, polyvinyl acetate (PVAc)/polyvinyl chloride (PVC) optimized MgO/PVAc/PVC polymer ...

G raham Hutchings of Cardiff University made a discovery in 1982 that came to define his career. He predicted that golddespite its reputation for being inertshould be an excellent catalyst for an industrial reaction that makes vinyl chloride monomer (VCM, or chloroethene), used to produce one of the world’s most ubiquitous plastics, polyvinyl chloride (PVC). More than three decades later, Hut...

Polyvinyl chloride (PVC) is one of the popular materials that extensively used in different areas, so scientists are trying to investigate its characteristics formats, such as blends and composites, improve properties. Due distinctive nano particles’ properties, polymer-based nanocomposites can offer new pure polymers widen their applications areas. In this study, we added compositions silicon ...

BACKGROUND There is a risk of drug sorption into an intravenous administration set composed of polyvinyl chloride (PVC), polyurethane (PU), or polyolefin (PO). This has implications on the dose of the active ingredient the patient receives, and thus therapeutic success. This study aimed to determine the plasma concentration of nitroglycerin and the effect of nitroglycerin on patients based on t...

Few studies have concentrated on the life history characteristics of arboreal anurans away from breeding ponds, and sampling of these species is difficult due to their ability to evade visual detection and other traditional herpetological census techniques. This study utilizes polyvinyl chloride (PVC) pipes to test for habitat selection of hylid treefrogs at the Natural Areas Teaching Lab in th...
