New methods are being developed to enable the production of value-added materials from high-volume, low-cost feedstocks arising from domestic recycling streams. In this work, recycled bottle-grade polyethylene terephthalate, polystyrene, and polypropylene were spun into fibers from the melt using a centrifugal spinning technique. Mono-component fibers and 50/50 blends of each polymer and a 33/3...

Polymer layer growth by free radical graft polymerization (FRGP) and controlled nitroxide-mediated graft polymerization (NMGP) of polystyrene was achieved by atmospheric pressure hydrogen plasma surface activation of silicon. Kinetic polystyrene layer growth by atmospheric pressure plasma-induced FRGP (APPI-FRGP) exhibited a maximum surface-grafted layer thickness (125 A after 20 h) at an initi...

A 64-year-old man was referred to our hospital with Methicillin-resistant Staphylococcus aureus (MRSA) infection following infrainguinal arterial reconstruction. As repeated MRSA sepsis occurred, we decided to remove the infected graft with distal revascularization via circuitous graft tunneling to avoid serious infections and allow limb salvage. An iliofemoro bypass was performed via an extra-...

Since 1940, mass production of polyolefin plastics produced annually has increased rapidly [1]. The most common plastics, which account for approximately 80% the European plastic demand, are: Polyethylene (PE), Polypropylene (PP), Poly (Vinyl Chloride) (PVC) and Polystyrene (PS) (Figure 1) [2]. Therefore, materials have experienced a substantial expansion, are used nowadays. These wide range ap...

This study demonstrates the efficacy of cold gaseous ozone treatments at low concentrations in the eradication of high Listeria monocytogenes viable cell loads from glass, polypropylene, stainless steel, and expanded polystyrene food-contact surfaces. Using a step by step approach, involving the selection of the most resistant strain-surface combinations, 11 Listeria sp. strains resulted inacti...

Identification of nanoplastics in complex environmental matrices remains a challenge. Despite the increase studies, there is lack studies dedicated to detection, partially explained by their carbon-based structure, wide variety composition, and low concentrations compared natural organic matter. Here, pyrolysis coupled GCMS instrumental setup provided relevant analytical response for polypropyl...
