Adhesion Effect

Chitosan is a kind of natural polymer commonly applied for nanomaterials, which is affluent in nature with favorable biodegradability and biocompatibility and free of toxicity or odor. In clinic it can be used as a drug carrier for the treatment of cancer, and also it is a kind of new pharmaceutical excipient. To prepare chitosan nanomaterial, various method are used, such as ionic crosslinking, covalent crosslinking, precipitation, free radical polymerization, reverse micelle, spray drying, and self-assembly. Furthermore, plenty of anti-tumor drugs, including adriamycin, epirubicin, taxol, 5-fluorouracil, norcantharidin, folic acid, and so on, are also attempted to load on these chitosan nanocarriers. In addition, the mechanism for those nanocarriers carrying anti-tumor drugs acting on tumor cell were explored, and the formulation mainly include electric charge adhesion effect, suppressing the proliferation of tumor cells, adjusting or enhancing immune ability of the body and inducing apoptosis. This paper compared the characteristics of different preparation methods on chitosan as a nanodrug carrier, summarized the types of packaged drugs, analyzed the mechanism of the chitosan as nanodrug carriers. It can provide valuable reference for researchers' further work.

Adhesion Effect

A brand new self-compensated capacitive fuel level sensor has been proposed in this paper. Through mathematics manipulation and theoretical analysis, we design the self-compensated structure of capacitive level sensor. The multiple segmentation structure makes compensation for temperature and medium possible. Furthermore, the effect caused by adhesion on the sensor electrodes if the adhesion fails to return initial position when the plane’s attitude is changing has been analyzed. Additionally, based on RF admittance theory, the transducer which can eliminate the adhesion effect has been designed and implemented using phase-locked sampling technique. Through level experiment and data analysis, the fuel level sensor proved to achieve all the destinations, including compensation for temperature and medium and elimination of adhesion effect. Hence, the accuracy of level measurement has been improved.

Adhesion Effect

The paper aims at studying the phenomenon of adhesion between the graphite pellicles deposited through electric discharges in pulse (EDI) with metal surfaces subjected to processing on the one hand and on the other hand the adhesion of this pellicle with a polyurethane adhesive. Experimental research has shown that, when the surfaces are not treated, the shear occurs in the adhesive, when the test pieces are covered with graphite pellicles the shear occurs on the surface that separates the pellicle from the adhesive. It has been stated experimentally that graphite pellicles deposited through electric discharges in pulse decrease the adhesion between the mating surfaces by at least 40% compared to the not treated surfaces.
