Silver nanoparticles (AgNPs) have drawn great attention due to their outstanding antibacterial effect in a wide range of applications, such as biomass packaging materials, wound dressings, flexible sensors, etc. However, the oxidation AgNPs limits effect. Firstly, effects pretreatment methods on property were investigated by shake flask method and agar diffusion plate method. Secondly, graphene...

The thermal conductivity of the diglycidyl ethers bisphenol-A (DGEBA)/4,4′-diaminodiphenylmethane (DDM)/polyethersulphone (PES)/silver (Ag) filler composites has been investigated. DGEBA/DDM/PES blend as matrix for polymer formed co-continuous phase structures at micrometer scale via reaction-induced separation during curing process. Ag fillers were selectively localized in epoxy-rich phases, a...

This paper provides a new account for why online processing of filler-gap relative clause dependencies is more difficult in cases where filler-gap interacts with object control than in cases involving subject control, as reported by Frazier et al. (1983). Frazier et al. (1983) argued for a Recent Filler heuristic in which the parser expects to discharge the most recent filler at every gap site....

Powder-liquid type metal-resin composites, using Ag-Sn irregular particles as the filler, 4-META as coupling agent and UDMA + TEGDMA as resin matrix, were experimentally prepared under 9 different conditions (three different particle sizes and three different filler contents). The flexural strength and flexural modulus were measured. Three different irregular particle size MRCs without redox-in...

Bio-composites have been formulated by exploiting post-industrial PLA derived from thin film production and silver skin, a by-product of the coffee’s roasting process. The mix design for compounds exploits effects regrading toughening agents. mechanical properties materials investigated as well thermal physical ones. recycled material mixed with additive shows good properties. filler addition i...

in this study, precipitated calcium carbonate (pcc) was modified using cationic starch, and its effect on optical and physical properties of paper was examined in comparison with unmodified filler afterwards. to determine the filler retention in paper, both modified and unmodified fillers were added to pulp suspensions by 20, 30, and 40 percentages. for comparing the utilization effect of modif...

Effect of different fillers on natural rubber compounds was investigated through curing, mechanical properties and morphology studies for improving mechanical performance of rubber articles. In this work, natural rubber blends with Silica as Single-filler compounds, and blends with Silica and Carbon black as Bi-filler compounds were considered. Then, natural rubber blends with Silica, Carbon bl...

normal 0 false false false en-us x-none fa background : the growing interest in filler injection requires a more comprehensive knowledge about the complications of this procedure. methods : a total of 5 cases with debilitating chronic complications following filler injection who were referred to al-zahra hospital, isfahan are presented in this report. results : the outcome of treatment for two ...

The morphological and compositional characterization of the filler particles in selected dental composites has been accomplished by a combination of backscattered elec tron imaging, digital imaging , energy dispersive X-ray analysis and thermogravimetry. Backscattered electron images provide excellent composition contrast between the filler and the matrix in this analysis . Qualitative energy d...
