Liquid Silicon Rubber (LSR) having the applications as liquid or elastomer is present in this group. Magnetorheological property is obtained by filling of liquid Silicon with iron particles. In this study, the influence of concentrations of spherical carbonyl iron particles on both viscoelastic properties and cross-linking behavior of liquid silicon was figured out. Polymer networks were synthesized by reacting of a commercially available chemical namely divinyl Polydimethylsiloxan [(CH3)2SiO]n containing platinum catalyst with a cross-linker namely methyl hydrogen siloxan (CH3(H)Si-O). In the structures of both chemicals, there are nano-silica (SiO2) particles. Rheological characterization of liquid silicon was carried out in a rotational Rheometer by dynamic mechanic test. Enhancement in the cross linking density and acceleration in the polymer network formation rate were observed with increasing temperature. SiO2-Particles/PDMS-Matrix and particle/particle interactions were found to occur with the increasing amount of filler material. In addition, it was observed that relaxation time and hence the frequent dependence of elasticity modulus (G’) was changed. Cross-linking behavior of the elastomer was examined by swelling test, and it was figured out that crosslinking density (interaction at the particle/matrix interface) was increased with the increasing amount of filler material.

Moreover, the results of our previous studies have demonstrated that after acetone:water (9:1) (AW) washing, the lignin content in HW-extracted wood decreased while hydrolysability increased. In this study the potential to increase accessibility of sugar maple (Acer saccharum) for EH was further explored by performing EB irradiation (bars; 250, 750 and 1000 kGy) followed by HWE (chips; 160 °C, 2 hours) and/or AW (chips; 120 °C, 20 min). After pretreatments (EB, HWE, EB_AW, EB_HWE, HWE_AW, EB_HWE_AW), wood was grounded to 30 mesh and EH was performed (Cellic ® CTec2, HTec2, Novozymes; 72 hours). Samples of hydrolysates collected throughout EH (sampling every 4 hour in duplicates) were analyzed for the concentration of glucose and xylose while the wood before and after EH was analyzed for the content of lignin and glucose and xylose-based polysaccharides. These studies are expected to enhance pretreatment procedure for the production of glucose from hardwoods by applying relatively mild and environmentally friendly procedure Sun, 22 Mar 2015 00:00:00 GMT http://hdl.handle.net/11508/8498 2015-03-22T00:00:00Z http://hdl.handle.net/11508/8360 "Performance Evaluation of Cement Mortars Containing Marble Dust and Glass Fiber Exposed to High Temperature by Using Taguchi Method", this article has been downloaded or viewed 784 times since publication.
