ABSTRACT
The arrays of metallic nanowires are considered as promising precursors for 1D semiconductor nanostructures after appropriate treatment at temperatures close to the melting point. Therefore the melting behaviour of the metallic structures in oxide templates is a key parameter for the subsequent conversion process. The present paper focuses on understanding of the effect of mechanical stress generated during heating on the melting point of the metal nanowires deposited into the pores of anodic alumina. Extremely high local compressive stress appears due to the difference in the thermal coefficients of the oxide template and nanowires inside the pores. The effect of the composite structural parameter that may be related to the concentration of nanowires on the melting temperature has been investigated. A numerical model predicting the melting point has been developed for composites with indium, tin, and zinc nanowires. The simulation results obtained using the suggested model were compared with the experimental data.
ABSTRACT
Experimentally on dogs the authors have elaborated a new method of treatment of postresection wound surface of the liver, spleen and pancreas by using a heated head of an electrothermocoagulator with subsequent sealing with BF-glue. The application of the method concerned allow secure hermetization of the wound surface. Thi method is insignificantly traumatic and is followed by no complications. Tissue responses to thermocoagulation and BF-glue anr not markedly pronounced. The method suggested by the authors seems to be advantageous for the clinical practice.
