Dielectric spectroscopy of polystyrene/poly(ethylene oxide) composites
(American Chemical Society: Macromolecules, 1996-07-01)
The effect of incorporating poly[styrene-b-(ethylene oxide)], PS-b-PEO into PS/PEO composites has been examined microscopically and dielectrically. The addition of block copolymer stabilizes the dispersion of PEO in PS and ...
Effect of crystallization on the morphologies of block copolymer/homopolymer blends cast in an electric field
(Wiley: Journal of Polymer Science Part B: Polymer Physics, 1996-01-30)
Blends of polystyrene (PS) and poly(styrene-b-ethylene oxide) (PS-b-PEO) were cast from a ternary solvent mixture containing 85% toluene, 10% tetrahydrofuran, and 5% methanol under conditions that favor crystallization of ...
Electric field-induced morphologies in diblock copolymer containing polymer blends
(American Chemical Society: Polymer Preprints, 1992-04)
Column-like structures can be generated in dc electric fields from normally spherical domain-forming binary and ternary blends. In ternary PS/PS-b-PEO-PEO blends, the addition of block copolymer stabilizes the elongated ...
Morphological granulometric analysis of electrophotographic images--size distribution statistics for process control
(The Society of Photo-Instrumentation Engineers (SPIE), 1991-04-01)
Size distributions of particles within a binary image can be generated
by morphological filtering processes known as granulometries.
Granulometries filter the image by structuring elements of ever-increasing
size, the ...
Specializations of the body form and food habits of snakes
(Oxford University Press: American Zoologist, 1983)
Viperid snakes have stouter bodies, larger heads, and longer jaws than snakes in other families; there are no major differences between the two subfamilies of vipers in these features. A suite of morphological characters ...
