Thermal degradation behavior, exothermic patterns, and kinetic parameters of symmetrically/asymmetrically substituted polysilanes during the kumada thermal rearrangement in temperature range 100–450 °C, were investigated applying thermogravimetric (TGA) differential scanning calorimetric (DSC) techniques. Three kinds polysilanes, viz., Polydimethylsilane (PDMS), Polydiphenylsilane (PDPS) Polyme...

Two silane coupling agents were used for hydrolysis-condensation reaction modification of nanosilica surfaces. The surface characteristics were analyzed using Fourier transform infrared spectroscopy (FTIR). The vulcanization kinetics of natural rubber (NR) + silica composites was studied and compared to behavior of the neat NR using differential scanning calorimetry (DSC) in the dynamic scan mo...

This study examines the kinetics of pyrolysis and oxidation hydrochars through thermal analysis. Thermogravimetric analysis (TGA) differential scanning calorimetry (DSC) techniques were used to investigate decomposition profiles develop two distributed activation energy models (DAEM) derived from hydrothermal carbonization grape seeds produced at different temperatures (180, 220, 250 °C). Data ...

BACKGROUND Inter-observer delineation variation has been detailed for many years in almost every tumor location. Inadequate delineation can impair the chance of cure and/or increase toxicity. The aim of our original work was to prospectively improve the homogeneity of delineation among all of the senior radiation oncologists in the Nord-Pas de Calais region, irrespective of the conditions of pr...

Polymer layered silicate (PLS) nanocomposites have been prepared with diglycidyl ether of bisphenol-A (DGEBA) epoxy resin as the matrix and organically modified montmorillonite (MMT) as the clay nanofiller. Resin-clay mixtures with different clay contents (zero, two, five and 10 wt%) were cured, both isothermally and non-isothermally, using a poly(ethyleneimine) hyperbranched polymer (HBP), the...

3-Deoxysappanchalcone (3-DSC) has been reported to possess anti-allergic, antiviral, anti-inflammatory and antioxidant activities. In the present study, we investigated the effects of 3-DSC on the proliferation of human hair follicle dermal papilla cells (HDPCs) and mouse hair growth in vivo. A real-time cell analyzer system, luciferase assay, Western blot and real-time polymerase chain reactio...

poly(ethylene adipte) and poly(ethylene adipate)/silica nanocomposite (pead/sio2) containing 3 wt. % sio2  were prepared by an in situ method. the examinations on the non-isothermal crystallization kinetic behavior have been conducted by means of differential scanning calorimeter (dsc). the avrami, ozawa, and combined avrami and ozawa equations were applied to describe the crystallization kinet...

This paper describes the integration of interactive statistical graphics within R using state-of-the art R-connectivity. The iPlots project uses SJava to deliver interactive plots for R and an associated framework for their customization. The graphical part of iPlots is implemented in Java. The design is discussed and some practical examples of iPlots are illustrated.
