The effectiveness of ultrasound and mechanical agitation for the recovery of Bacillus subtilis spores from pre-inoculated glass, polystyrene, polypropylene, polyethylene and polycarbonate surfaces was tested in the presence and absence of surfactant. Recovery from polymers was improved by the use of ...
The plastic manufacturers, based on the properties and usage, have categorized plastics as Polyethylene Terephthalate (PET 1),High-Density Polyethylene (HDPE 2), Low-Density Polyethylene (LDPE 4),Polyvinyl Chloride(V3),Polypropylene (PP 5), Polystyrene (PS 6), Miscellaneous types of Plastic (Other...
The mixing process involved placing 10 mL of the sample in a 20-mL polyethylene counting vial to which 10 mL of the scintillation cocktail was added. All chemical reagents used were of analytical purity, and the resistivity of Milli-Q®ultrapure water was 18.2 MΩ.cm in the experiments....
Examples of polyolefin compounds include polyethylene (formed from the olefin ethylene),polypropylene(formed from the olefin propylene), polymethylpentane, etc. In the industrial scale productions, these polymers are made in the presence of a catalyst such as Ziegler-Natta catalyst. What is Polyethylene?
Synthetic polymers are also used widely for different purposes. Polyethylene, polypropylene, PVC, nylon, and, Bakelite are some synthetic polymers. When producing synthetic polymers, the process should always be highly controlled to get the desired product. Synthetic polymers are important as adhesives,...
