The propenies of the interphase in wood-polymer composites ~ important determinaou of the propenies of the final composite. This study used inverse ps chromatOll'Bphy (IGC) to measure interpbasal propenies of composites of polystyrene and two types of wood fiber fillers and an inOllaDic substrate (CW) with varying amounts of surface cove,. of polystyrene. Glass transition temperatures, thennody...

polypropylene / polystyrene blends containing montmorillonite (mmt) were prepared using a twin screw extruder followed by fiber spinning. the melt intercalation of pp and ps alloys was carried out in the presence of a compatibilizer such as maleic anhydride-g-polypropylene (mpp). the crystallization morphology, thermal behaviors and mechanical properties of polypropylene/polystyrene (pp/ps) nan...

background: mosquitoes transmit several diseases to human. there are several measures for control of larvae. as part of integrated vector management (ivm) program, the utility of floating layers of polystyrene beads (eps) is a po­ten­tial alternative in habitats of mosquito larva. eps beads prevent oviposition of mosquito as well as killing the im­ma­ture stages by forming a tick layer on the w...

The performance of gold and polystyrene nanoparticles was investigated using quartz crystal microbalance (QCM) as sensor platform; β-Galactosidase antibody with corresponding antigen was utilized for the immunoreaction. The development of the immunosensor included: 1) formation of self assembled monolayers on quartz crystals; 2a) immobilization of p-aminothiophenol functionalized gold nanoparti...

Biofilm formation may play an important role in the pathogenesis of infections caused by Enterococcus faecalis, including endocarditis. Most biofilm studies use a polystyrene dish assay to quantify biofilm biomass. However, recent studies of E. faecalis strains in tissue and animal models suggest that polystyrene dish results need to be interpreted with caution. We evaluated 158 clinical E. fae...

Previously we demonstrated ultra-dense patterning using 2 kg/mol polystyrene negative electron beam resist that has low sensitivity [16]. To drastically improve its sensitivity, here we studied the expos...

The understanding of size-dependent properties is key to the implementation of nanotechnology. One controversial and unresolved topic is the influence of characteristic size on the glass transition temperature (T(g)) for ultrathin films and other nanoscale geometries. We show that T(g) does depend on size for polystyrene spherical domains with diameters from 20 to 70 nm which are formed from ph...

The rate/temperature dependent fracture behaviour of plain and glass-filled polystyrene has been investigated over the crack speed (a) range of 10 -6 to 10 -2 m sec -1 and in the temperature (7-) range of 296 to 363 K. The Kc (a, T) relationships obtained, where Kc is the stress intensity factor at fracture, are shown to follow those given by the Williams/ Marshall relaxation crack growth model...
