411. Certification of the Relative Molecular Mass and the Intrinsic Viscosity of SRM 2887, a Polyethylene of Narrow Molecular Mass Distribution
NIST Interagency/Internal Report (NISTIR)
J R. Maurey, William R. Blair, Carl R. Schultesiz
The certification of a polyethylene standard reference material, SRM 2887, is described. The Mw of SRM 2887 by light scattering was determined to be 196.4x10+3 g/mol with a sample standard deviation of 6.7 x10+3 g/mol. A combined expanded uncertaint ...
412. Origins of enhanced capacity retention in copolymerized sulfur - based composite cathodes for high-energy density Li-S batteries
Vladimir Pavlovich Oleshko, Jenny J. Kim, Jennifer L. Schaefer, Steven D Hudson, Christopher L Soles, Adam Simmonds, Jared Griebel, Kookheon Char, Jeff Pyun
Poly(sulfur-random-(1,3-diisopropenylbenzene) (poly(S-r-DIB)) copolymers synthesized via inverse vulcanization form high molecular mass electrochemically active polymers capable of realizing enhanced capacity retention (1005 mAh/g at 100 cycles) and ...
