Hidration kinetics study of tlie mixed cements

Gabriel . L Duque Fernández、David Díaz Quintanilla、Manuel Zapata Sierra 等 4 位作者1993-09-01Materiales de Construccion

A study of the hydration process of cements with 10% and 20% addition of a tuff from "Las Carolinas" quarry (Cienfuegos, Cuba) by different methods was done. The results obtained by different methods showed a good agreement. It was proved an increment of the hydration products, an acceleration of alite hydration and a…

Synthesis of Conducting Polymer Composite Fibers in Electrochemical Flow Cells

Shulong Li、Henry S. White1993-09-01Journal of The Electrochemical Society

A one‐step electrochemical synthesis of polymer and composite polymer fibers of macroscopic dimensions (>10 cm length and 0.2 mm diam) is reported. Poly(3‐methylthiophene) and polypyrrole fibers are grown from the tip of a Pt microelectrode by oxidation of 3‐methylthiophene and pyrrole, respectively, in a capillary fl…

Electrochemistry of Conductive Polymers: XIV . In Situ Spectroelectrochemical and Kinetic Studies on Poly(3‐Methylthiophene) Growth

Sally N. Hoier、Su‐Moon Park1993-09-01Journal of The Electrochemical Society

The growth mechanism of poly(3‐methylthiophene) has been studied employing in situ spectroelectrochemical and kinetic measurements. Results indicate that: ( i ) the polymer film grows only when 3‐methylthiophene is oxidized, suggesting that the radical‐radical coupling reaction is important for the polymer growth; ( i…

Dynamic light scattering with a CCD camera

Apollo P. Y. Wong、Pierre Wiltzius1993-09-01Review of Scientific Instruments

We have successfully implemented a method to measure intensity autocorrelation functions with a CCD camera and a fast computer. We report light scattering experiments on solutions of diffusing latex spheres in glycerol and compare our results to those obtained with a conventional hardwired electronic correlator. Avera…
