ABSTRACT Background: In timber structures, connections are the most important and critical section which supply strength of each structural element. The aim this study was evaluation behavior epoxy resin reinforced by nanoclay (at three levels) on pull-out glued-in GFRP rods in glulam. For purpose, two with lengths (50, 150 250 mm) diameters (6.4, 12.7 19.1 were inserted at opposite sides glula...

Glass ionomer cement (GIC) represents a major transformation in restorative dentistry. Wear of dental restoratives is a common phenomenon and the determination of the wear resistance of direct-restorative materials is a challenging task. The aim of this paper was to evaluate the wear resistance of novel glass ionomer cement by two wear-test methods and to compare the two wear methods.The wear r...

Ghezeljeh montmorillonite nanoclay was used as a natural adsorbent to measure and remove copper ions released from the cooking pot into food by applying the solid phase extraction (SPE) method in batch mode. The clay is characterized by using fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM) and X-ray diffractometry (XRD). The results of XRD and FT-IR of n...

Sepiolite is a magnesium silicate-containing nanoclay mineral and is utilized as a nanofiller for nanocomposite applications. We postulated that lung exposures to Sepiolite clay samples could produce sustained effects. Accordingly, the pulmonary and extrapulmonary systemic impacts in rats of intratracheally instilled Sepiolite nanoclay samples were compared with quartz or ultrafine (uf) titaniu...

atom transfer radical polymerization of styrene (st) and methyl methacrylate (mma) was performed at 90oc in the absence and presence of nanoclay (cloisite 30b). trichloromethyl-terminated poly(vinyl acetate) telomerand cucl/ pmdeta were used as a macroinitiator and catalyst system, respectively. the experimental results showed that the atom transfer radical polymerization of st and mma in the a...

Room temperature direct-ink-write printing of epoxy-nanoclay-carbon fiber composites produces parts with high stiffness and strength. Establishing clear relationships between print parameters, filler orientation, properties is difficult, in part owing to challenges characterization. Here, we perform scanning microbeam X-ray scattering 5 micrometer spatial resolution on cross-sections printed (a...

Wastewater recovery is one of the most pressing contaminant-related subjects in textile industry. Many cleaning and techniques have been applied recent decades, from physical separation to chemical separation. This work reviews wastewater by focusing on natural or synthetic nanoclays order compare their capabilities. Presently, a wide variety are available that can adsorb substances dissolved w...
