  • Polyacrylamide Gel Electrophoresis: Advantages and ...

    (vi) Possibility of high purity of starting material can also be achieved. (vii) Precise control over the doping level is also easier in this process. Disadvantages-The process is not very ‘clean’. As the process involves chemical reactions between several ingredients in solution, it contains undesired atoms, molecules, ions, etc., in the required material, which deteriorates the electrical as well as optical properties of the deposited material.

  • Experimental investigation on size degradation of bridging ...

    2019-1-15 · Based on “D 90 Rule”, the selected material size D 90 should be equal or close to the maximum pore-throat size or fracture width. Then, drilling-fluid loss will be prevented or controlled as the stable bridge of solid particles is built at the smaller size of the pore throats or fractures near the wellbore, which will work well for FDP/FDC.
