In this paper we fabricate nonlinear optical nanocomposite based on CdSe quantum dots mixed with commercial photoresist SU-8, which can be structured by two-photon polymerization lithography. The ...distribution of quantum dots in the polymer was measured by transmission electron microscopy. Nonlinear optical properties of nanocomposite films were studied by third harmonic generation technique. We estimated the nonlinear cubic susceptibility of our nanocomposite.
The article is dedicated to BDO Code program complex used for modelling and optimization of charged particle dynamics with consideration of interaction in RFQ accelerating structures. The structure ...of the program complex and its functionality are described; mathematical models of charged particle dynamics, interaction models and methods of optimization are given.
Treatment results of 59 patients with the complicated ulcer disease were analyzed. Authors prove, that in cases of perforative duodenal ulcer, the operation should aim the treatment of all the ...complications. The use of 2/3 gaster resection in combination with Jadd pyloroplasty and trunk vagotomy led to the decrease of the lethality rate on 21%.
The work is devoted to the study of the processes of formation of multilayer nanostructures, their vacuum deposition, and the manufacture of a novel functional element of spintronics - ...superconducting spin valve, which is a multilayer structure consisting of ferromagnetic cobalt nanolayers separated by superconductor niobium films. Multilayer nanostructures are fabricated by magnetron sputtering on (111) silicon substrates at a temperature of 300K. The prototypes of the superconducting spin valve are prepared from multilayer nanostructures by the method of sharp focus reactive ion etching (FIB). Modeling was carried out using molecular dynamics methods.
