Introduction Olefin polymers are the most widely used materials in the plastics industry today. To optimize their properties and processibility, blending is often used. This is particularly important for the metallocene-catalyst based polyolefins. By altering certain shear-thinning and strain-hardening characteristics, blending can enhance the processibility of the material. This is in addition...

in this research, effects of concentration and time of silane treatment of rice straw flour on the morphology and mechanical strengths of rice straw flour/polypropylene composites were investigated. tri ethoxy vinyl silane (c8h18o3si) with 98% purity in two concentrations of 5 and 10%, that each concentration had two immersion times including, 45 and 90 min for using treatment rice straw flour....

PURPOSE The stability of docetaxel diluted to 0.3 or 0.9 mg/mL with 0.9% sodium chloride injection and stored in polyolefin or glass containers was studied. METHODS Vials of docetaxel injection concentrate were reconstituted with the entire contents of the solvent vial and carefully homogenized to avoid the formation of foam. Solutions were aseptically prepared with nominal docetaxel concentr...

Increased environmental concerns and global warming have diverted effort all over the world to focus on renewable sustainable resources for next generation of composite products due their recyclability, renewability, cost effectiveness, satisfactory mechanical performance. Bio/natural fibers which are environment friendly materials employed as reinforcement led developing a biocomposite reducti...

Introduction: The selection of porcelain is based on high biocompatibility, endurance, superficial texture and aesthetics. Nevertheless, the innate fracture charateritics of porcelain is the main cause of the intra oral fractures. Electing a suitable porcelain restorative system in terms of stability of color is important. For this reason, this study aimed to examine the color changes of common...

Fog represents a large untapped source of potable water, especially in arid climates. Numerous plants and animals use textural and chemical features on their surfaces to harvest this precious resource. In this work, we investigate the influence of the surface wettability characteristics, length scale, and weave density on the fog-harvesting capability of woven meshes. We develop a combined hydr...

mgcl2/c2h5oh adducts with constant relative ratio of 1/3 were prepared and kept at 120oc for different lengths of times of 5, 10, 20, 30, 50, 90,120 and 220 h. then the samples were quenched and analyzed by xrd and bet. no meaningful changes were observed in the specific surface area of the samples, while xrd spectra showed 3 peaks at 2θ<15o for samples kept at 120oc for 5 h. these 3 peaks were...
