Morphology, Microstructure, and Rheology of Amphiphilic Telechelics Incorporating Polyhedral Oligosilsesquioxane
Amphiphilic telechelics incorporating polyhedral oligosilsesquioxane (POSS) end-caps were synthesized and studied as a novel building block for the construction of inorganic-organic hybrid materials. Their micron-scale morphologies were investigated using hot-stage polarizing optical microscopy (POM), revealing a dramatic influence of POSS macromer incorporation. The molecular-scale crystalline...
متن کاملPolyhedral Serpentine Grains in Cm Chondrites
Introduction: CM chondrites are primitive rocks that experienced aqueous alteration in the early solar system. Their matrices and fine-grained rims (FGRs) sustained the effects of alteration, and the minerals within them hold clues to the aqueous reactions. Sheet silicates are an important product of alteration, and those of the serpentine group are abundant in the CM2 chondrites. Here we expan...

15 صفحه اولThe Effect of Siliconizing and Borosiliconizing Processes on Microstructure and Morphology of Carbon Steel Surface Layers
A study for optimizing of siliconizing and borosiliconizing processes on carbon steels has been carried out. The process parameters, i.e, time and powder mixture, were considered for optimization of the case depth, surface quality and the hardness profile. Time and temperature of the processes were 4 hr and 950˚C, respectively. Powder mixture in siliconizing process was 2.5% ferrosilicon, 2.5%...
