Electrostatic flocking is applied to create an array of aligned carbon fibers from which an elastomeric thermal interface material (TIM) can be fabricated with a high through-plane thermal conductivity of 23.3 W/mK. A high thermal conductivity can be achieved with a significantly low filler level (13.2 wt%). As a result, this material retains the intrinsic properties of the matrix, i.e., elastomeric behavior.
Carbon-13 NMR spectra have been observed for 11- and 13-cis-retinals and their Schiff base linkage compounds with butylamine as a model compound of visual chromophore. The chemical shift changes on going from retinal to Schiff base. The changes in chemical shifts of polyene carbons were discussed in correlation with the changes of π-electron densities.
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.
