The term “nanocomposite” is widely employed to describe an extremely broad range of materials, where one of the components has a dimension in the sub-micron scale. A better –and far more restrictive– definition would require that a true nanocomposite should be a fundamentally new material (hybrid) in which the nanometer scale component or structure gives rise to intrinsically new properties, wh...

Abstract An innovative cost-effective and lead-free polymer nanocomposite of polyvinyl alcohol/ pyrrolidone was developed. PVA/PVP film contained spherical AgCl SnO 2 nanoparticles facilely prepared via a one-pot synthesis method. The route affords uniform dispersion the both unique features insoluble, dense, nonporous properties. new achieved an efficient gamma radiation attenuation capability...

The state-of-the-art Bismuth-Telluride (Bi2Te3) based systems are promising thermoelectric materials for efficient applications. In this study, the effect of graphene nanosheets (GNS) integrity on properties a p-type Bi0.4Sb1.6Te3 alloy has been studied using high-energy ball milling and SPS sintering techniques. synthesized pristine 0.05wt% GNS/Bi0.4Sb1.6Te3 nanocomposites at different additio...

INTRODUCTION In esthetic treatments with dermal fillers, increasing numbers of physicians are using the technique of mixing an anesthetic agent into the dermal filler before treatment to increase the comfort of the patients. This study aimed at evaluating the effects on the physical properties of a polycaprolactone (PCL)-based dermal filler after mixing with lidocaine. METHODS A range of 2.0%...

Aiming to develop more robust, mechanically advanced, Fused Filament Fabrication (FFF) materials, High-Density Polyethylene (HDPE) nanocomposites were developed in the current research work. Titanium Dioxide (TiO2) was selected as filler be incorporated into HDPE matrix concentration steps of 0.5, 2.5, 5, and 10 wt.%. 3D printing nanocomposite filaments extruded ~1.75 mm diameter used print tes...

In this paper, we develop a keyword spotting system using vocabulary-independent speech recognition technique, and investigate several non-keyword modeling methods to improve its performance. In order to overcome the weakness of conventional syllable model, we propose the syllable filler based on syllable information of keywords and syllable-like filler model. The former prohibits syllable fill...

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...
