DNA Sequencing by Capillary Electrophoresis Using Quasi-interpenetrating Network Formed by Polyacrylamide and Poly（N-hydroxymethylacrylamide）

Capillary electrophoresis (CE) in conjunction with laser induced fluorescence (LIF) is a powerful tool for DNA sequencing1. A number of water-soluble polymers have been used for this purpose. We have recently reviewed studies on separation medium on DNA s…     

A Novel Method for Preparing Polyurethane Based Conductive Composites with Low Percolation Threshold

A novel method for preparing conductive carbon black filled polymer composites with low percolation threshold from polyurethane emulsion are reported in this paper. The experimental results indicate that with a rise in carbon black concentration the insulator-conductor transition in the emulsion blended composites occurs at 0.8-1.4vol%. In contrast, the solution blended composites exhibit drastic increase in conductivity at conducting filler fraction as high as 12.3-13.3vol%. It is demonstrated that the composites microstructure rather than chemical structure of the matrix polymer predominantly determines the electrical conduction performance of the composites.

对Debye—Htickel理论的再认识——离子活度系数公式中渗透项的意义和作用

指出Debye-Htickel离子活度系数公式中，除了静电作用项以外还有另一项，称之为渗透项．渗透项鲜为人知，故着重讨论该项的意义和作用．
