Abstract: The present disclosure discloses a memory access interface device. A clock generation circuit generates reference signals. A transmitter transmits an output command and address signal to a memory device according to the reference signals. A signal training circuit executes a training process in a training mode that includes steps outlined below. A training signal is generated such that the training signal is transmitted as the output command and address signal. The training signal and the data signal generated by the memory device are compared to generate a comparison result indicating whether the data signal matches the training signal. The comparison result is stored. The clock generation circuit is controlled to modify a phase of at least one of the reference signals to be one of a plurality of under-test phases to execute a new loop of the training process until all the under-test phases are trained.

Abstract: A method for fabricating an aligned graphene sheet-polymer composite is provided, which includes the steps below. A mixture is prepared with the dispersed graphene sheets in the polymer fluid. The graphene filament bundles substantially paralleled to each other are formed by a sequence of aligned graphene sheets in the polymer fluids when a field was applied. Finally, the mixture is solidified. An anisotropic index in a range of 1.00 to 2.00 is obtained in an aligned graphene sheet-polymer composite by calculating the ratio of the coefficient of thermal conductivity in a parallel direction and the one in perpendicular direction. The aligned graphene sheet-polymer composite is also provided.

Abstract: Redispersible polymer powders made by core-shell polymers having an alkali-soluble emulsion polymer shell and an aqueous-insoluble emulsion polymer core wherein the core and the shell polymers are chemically grafted by utilizing a polyfunctional compound. The core-shell polymers are produced by a two-stage sequential emulsion polymerization process in which an alkali-insoluble emulsion polymer core is polymerized in the presence of an alkali-solubilized emulsion polymer. When the core-shell polymer powders of this invention are employed as a cement modifier, improvements in the powder physical properties and cement mortar properties are realized.
