Three-dimensional study of cylindrical morphology in a styrene-butadiene-styrene block copolymer
When a block copolymer undergoes microphase separation, well ordered microstructures result which give the copolymer unique thermal and mechanical properties. In relating these properties quantitatively to the microstructure, and in devising models for the phase separation, theoreticians have always invoked highly idealized structural elements. However, variations in the actual microstructure m...
متن کاملButadiene and Styrene Risks
The control of cell proliferation by gastrin has been investigated in a rat pancreatic tumour cell line, AR4-2J. Exogenous gastrin, 10-12 to 10-8 M, stimulated cell growth of thymidine-synchronised AR4-2J cells cultured over 48 h in serum-free medium. Cell lysates of AR4-2J cells contained an average of 4.5 and 3.5 pg gastrin per 106 cells, when grown in serum-supplemented or serum-free media, ...

متن کاملExtending the scope of poly(styrene)-block-poly(methyl methacrylate) for directed self assembly
Directed self-assembly (DSA) is a promising technique for extending conventional lithographic techniques by being able to print features with critical dimensions under 10 nm. The most widely studied block copolymer system is polystyreneblock-polymethyl methacrylate (PS-b-PMMA). The system is well understood in terms of its synthesis, properties and performance in DSA. However, PS-b-PMMA also ha...
