Because of this property, water is preferentially adsorbed by these surfaces, and large organic compounds cannot compete with strongly held water for adsorption sites on the clay surfaces. Thus, Na-clays are ine_ective sorbents for small organic molecules. However, it is possible to modify the surface properties of clays greatly by neutralizing the anionic framework of layer silicates by using positively charged organic species such as alkylammonim ions. In the modi_ed form (HDTMA-bentonite), the clay surface may become organophilic and interact strongly with organic compounds. Textile dyes represent a relatively large group of organic chemicals. In an HDTMA-bentonite-dye system it is possible that adsorption may be enhanced by the hydrophobic interaction between the adsorbed dye molecule and HDTMA-bentonite.

Accordingly three DNA computing models, the solution-based model, surface-based model and the combination of solution and surface-based model, were presented to solve 0-1 programming problem in the study. The advantages of massive parallelism, high-density storage and potential robotization of solution-based and surface-based model were well embodied and their shortages such as timewasting operations and less massive parallelism were also avoided by all means in these models.

Two kinds of silicon samples with distinct surface treatment, i. e., one surface was chemically etched and the other was unetched, were used to investigate the characteristics of leakage current and surface flashover of semiconductor under impulse voltage in vacuum. The experimental results showed that the surface conditions of samples affected these characteristics greatly. Before flashover, the Ohmic current was observed for unetched samples and the space charge limited current for etched samples, respectively. Meanwhile both samples showed quite different flashover tracks, and the surface-etched samples displayed a much higher onset voltage of flashover.
