The formation of various bicontinuous phases from binary blends linear AB diblock copolymers (DBCPs) is studied using the polymeric self-consistent field theory. theoretical study predicts that double-diamond and "plumber's nightmare" phases, which are metastable for neat copolymers, could be stabilized in block with designed dispersity, namely, composed a gyroid-forming DBCP homopolymer-like D...
Earlier work on mechanical properties and their relation to phase diagrams is complemented here by theological and further morphological studies using an optical microscope and polarizing light, for the system studied previously and also for three other binary blend systems. The polymer liquid crystal (PLC) is the same in all, PET/0.6PHB, where PET = poly(ethylene terephthalate), PHB = p-hydrox...
– We have used quantitative X-ray microscopy in combination with Scanning Force Microscopy to monitor the phase separation of spun cast thin films of polystyrene and poly(methyl methacrylate) blends upon annealing. Both techniques complement and enhance each other in elucidating the complicated structures that develop as a function of annealing time. We have determined the composition of the mi...
abstract biometric access control is an automatic system that intelligently provides the access of special actions to predefined individuals. it may use one or more unique features of humans, like fingerprint, iris, gesture, 2d and 3d face images. 2d face image is one of the important features with useful and reliable information for recognition of individuals and systems based on this ...
