Due to increasing health and environmental issues, indoor air quality (IAQ) has garnered much research attention with regard incorporating advanced clean technologies. Various physicochemical treatments have been used monitor, control, manage contaminants, such as monitoring devices (gas sensors internet of things-based systems), filtration (mechanical electrical), adsorption, UV disinfection, ...

?2 microglobulin (?2m) fibril has been recognized as the major factor of dialysis-related amyloidosis. elevated serum levels are thought to be the basis for tissue deposition. in order to evaluate the effect of cellulosis membrane (fb 110) and treatment duration on s?2m levels, we determined serum levels in 23 hemodialyzed patients with end-stage renal failure. s?2m levels were markedly elevate...

the purpose of this study was to compare the presence or absence of uv irradiation on the separation performance and morphology of the tio2-assembled thin film membranes (in different concentrations). furthermore, an attempt was made to show and compare the effect of the presence of tio2 nanoparticles in aqueous and organic phases during the interfacial polymerization process. sem, zeta potenti...

BACKGROUND The aim of this study was to evaluate the interaction of bioactive and biodegradable poly (lactide-co-glycolide)/bioactive glass/hydroxyapatite (PBGHA) and poly (lactide-co-glycolide)/bioactive glass (PBG) nanocomposite coatings with bone. MATERIALS AND METHODS Sol-gel derived 58S bioactive glass nanoparticles, 50/50 wt% poly (lactic acid)/poly (glycolic acid) and hydroxyapatite na...

Outdoor electronic equipment such as signal stations, radar units, and cellular base stations would benefit from electromagnetic interference (EMI) shielding systems, but ice accretion on the surface of these facilities often causes critical challenges, especially in cold regions winter season. In this study, icephobic nanocomposite electrospun membranes were developed via a two-step process re...

integrally skinned asymmetric membranes based on nanocompositepolyethersulfone were prepared by the phase separation process using the supercritical co2 as a nonsolvent for the polymer solution. in present study, the effects of temperature and nanoparticle on selectivity performance and permeability of gases has beeninvestigated. it is shown that the presence of silica nanoparticles not only di...
