The effects of three different mixers, two different feeding orders and nanoclay content on the structure development and rheological properties of PE/nanoclay nanocomposite samples were investigated. Fractional Zener and Carreau–Yasuda models were applied to discuss the melt linear viscoelastic properties of the samples. Moreover, scaling law for fractal networks was used to quantify clay disp...

Perovskite solar cells have received considerable attention in recent years as a promisingmaterial capable of developing high performance photovoltaic devices at a low cost. Their high absorption coefficient, tunable band gap, low temperature processing and abundant elemental constituents provide numerous advantages overmost thin film absorbermaterials. In this review, we discuss the current st...

introduction: the purpose of this study was to compare the setting time and post-setting solubility, flow, film thickness and dimensional changes of ah26 root canal sealer with ah26-antibiotic combination. materials and methods: this study was performed according to british standard bs 6876 (2001) which tests the physicochemical properties of endodontic sealers. three samples of each of tested ...

The degradation behavior of silk fibroin biomaterials in human body is definitely vital for the growth of tissues. Therefore, an investigation to regulate the degradation behaviors of silk fibroin films by changing the degree of cross-linking is presented in this paper. The in-vitro experiments in the simulated human body environment showed that the degradation rate of cross-linked silk fibroin...

In the present study, packaging of a greenhouse-grown tomato on the culture medium containing 0, 25, 50, 75 and 100% compost tea under modified atmosphere: MA (88%N2 + 8%CO2 + 4%O2) in polyethylene and nanosilicon-polyethylene bags was studied at 5°C for 30 days. Several quality parameters such as moisture content, pH, total soluble solids (TSS), titratable acidity (TA), Vitamin C content, text...

Numerical Simulations are employed to create amorphous nano-films of a chosen thickness on a crystalline substrate which induces strain on the film. The films are grown by a vapor deposition technique which was recently developed to create very stable glassy films. Using the exact relations between the Hessian matrix and the shear and bulk moduli we explore the mechanical properties of the nano...

Cu3Ge has been pursued as next-generation interconnection/contact material due to its high thermal stability, low bulk resistivity and diffusion barrier property. Improvements in electrical performance and structure of Cu3Ge have attracted great attention in the past decades. Despite the remarkable progress in Cu3Ge fabrication on various substrates by different deposition methods, polycrystall...
