Abstract: We perform directed self-assembly based on graphoepitaxy of lamellar forming six-arm star-shaped poly(methyl methacrylate)-block-polystyrene copolymer thin film. The affinity between each block and the trench wall is adjusted by using polymer brushes or selective gold… read more here.

Abstract: Abstract Six-arm star polycaprolactone with core of cyclotriphosphazene (s-PCL) was synthesized via ring-opening polymerization and characterized by NMR and GPC. Epoxy thermosets incorporating 10–40 wt% of this copolymer were cured with 4,4′-methylenebis(2-chloroaniline) (MOCA) and 4,4′-diaminodiphenyl sulfone… read more here.

DOI: 10.1190/geo2017-0761.1
Abstract: We have developed a robust and reliable method for determining borehole shape from six-arm caliper logs. Four- and six-arm calipers are the common caliper tools used in open-hole logging. They provide information about wellbore geometry… read more here.
