A new layout of complementary logic circuits based on p‐channel carbon nanotube and n‐channel zinc oxide nanowire transistors is presented by Takhee Lee and co‐workers . The processing is a hybrid approach, combining advantageous characteristic functions for the modulation of the current and operating voltage in transistors through proton radiation‐generated charges, allowing a simple method of designing favorable logic circuits.
The ternary diagram involving a rigid polymer [poly(p‐benzamide) (PBA)], a flexible polymer [poly(2‐phenylene(5‐benzimidazole)isophthalamide)
(PABI)] and a diluent composed of dimethylacetamide plus 3 wt.‐% LiCl (DMAc/3LiCl) was investigated. Addition of PABI to PBA solutions increases the critical volume fraction value at which a nematic phase is observed. The line connecting these values at different PBA/PABI ratios divides a region of isotropic solutions from a biphasic area. No case of a single anisotropic phase was observed. A peculiarity of the diagram is that the composition of the anisotropic phase in the biphasic region lies on the PBA‐diluent axis when the molecular weight of PABI is relatively high, whereas it shows a small content of PABI when its molecular weight is low. This result has recently been theoretically predicted by considering the existence of anisotropic interactions in the mesophase. The agreement between theoretical and experimental phase diagrams is fairly good.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
