Then dissolve the precipitate with octane. During the two-step pur- ification process, methyl acetate was added to the QDs solution. The mixture was then centrifuged to collect the precipitant and dissolve in th
Thus, AE may be considered as the quotient of the ratio of the molecular mass of the product and its corresponding precursors in a balanced chemical reaction [131]. It can be obtained from the stoichiometric equation of the reaction, where 100 % theoretical yield of the products is assumed....
The subject is to show a liquid crystal composition in which the homeotropic alignment of liquid crystal molecules can be achieved by the action of a polymer, and a liquid crystal d
those having an electric resistance of at least 102Ωcm and a dielectric constant of not more than 3.5 are useful. Exemplary carrier liquids include straight-chain or branched-chain aliphatic hydrocarbons and the halogen substitution products thereof. Examples of these materials include octane, isooctan...
(octanedioic acid), azelaic acid (nonanedioic acid), sebacic acid (decanedioic acid), undecanedioic acid, dodecanedioic acid, etc. A plurality of aliphatic dicarboxylic acids (and/or the esterified derivative thereof) optionally may be employed; however, in a preferred embodiment a single ...
The invention also provides a liquid crystal composition that is suitably balanced between at least two of the characteristics. The invention also provides a liquid crystal display device that contains such a composition. The invention also provides a composition that includes a polymer and has ...
