Abstract
Al2O3 and ZnO filled poly(methyl methacrylate) nanocomposites were synthesized by free radical (bulk) polymerization. Efficient dispersion was achieved by predispersing the nanoparticles in propylene glycol methyl ether acetate (PGMEA) followed by ultrasonication of nanoparticles into the PMMA syrup. Thermal analysis confirms chemisorption between PGMEA and metal oxide particles. The addition of nanoparticle affects degradation mechanism and consequently improves thermal stability of PMMA. The reduction of polymer chain mobility and the tendency of nanoparticles to eliminate free radicals are the principal effects responsible for these enhancements.
Abstract
By shortening the time to pathogen identification and allowing for detection of organisms missed by blood culture, new molecular methods may provide clinical benefits for the management of patients with sepsis. While a number of reviews on the diagnosis of sepsis have recently been published we here present up-to-date new developments including multiplex PCR, mass spectrometry and array techniques. We focus on those techniques that are commercially available and for which clinical studies have been performed and published.
