The films were deposited using electron beam evaporation technique. The films were annealed in air in the temperature range 200-550 oC. It was found that the annealing temperature has a significant effect on the optical properties of these films. The films are transparent in the visible region with average transmission of 83%. A high optical energy-gap of 3.65 eV was achieved at temperature 500 oC. Many optical parameters such as: refractive index; extinction coefficient; degree of inhomogeneity; dielectric constants; single oscillator energy; dispersion energy; oscillator strength; average oscillator wavelength; static dielectric constant; high frequency dielectric constant; thermal emissivity and optical resistivity were calculated as a function of annealing temperature. Finally, SnO2 films can be used in transparent heat mirror coatings applications due to their low thermal emissivity at high annealing temperature.","PeriodicalId":448231,"journal":{"name":"International Review of Physics","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128135001","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the present work, the dielectric and microwave properties of natural rubber (SMR10) based composites containing various concentration of fullerene black (0-7,5 phr), rich in fullerenes (7,5%) were investigated in the 1-12 GHz frequency range. It has been established that within the range used for the experiments the increasing frequency and fullerene filler amount lead to an increase in the values of relative dielectric permittivity, dielectric loss angle tangent, reflection coefficient and attenuation of electromagnetic waves, while the values for shielding effectiveness get lower. That is due to the fact that under the experimental conditions the change in the reflection coefficient is greater than that in the attenuation of electromagnetic waves. The dielectric properties of the composites (especially the dielectric loss angle tangent) are more affected by fullerene black filler than their microwave properties. Further change in the properties could also occur at higher concentrations of fullerene black but the cost of rubber compound would be much higher","PeriodicalId":448231,"journal":{"name":"International Review of Physics","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123745354","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our purpose is to expose, in a concise and entertaining way by utilizing modern computational techniques, a better understanding of the influence of Euler; also, to establish the remarkable significance in  the history of science. A first analysis was done with the series that defines Euler and Bernoulli numbers and polynomials of Bernoulli and Euler; an additional result is the characterization of the functions that lead to the Euler-Mascheroni constant. In hydrodynamics it is also feasible to evaluate graphically the connection between sizes in diameter and the exit angle of the height of Euler for turbo-machines. In differential equations of Cauchy-Euler solutions in the cases of distinct real roots and complex roots are generated. Furthermore we report the generation of the Fourier series and the Fourier transform calculated by using direct Matlab commands. In calculus of variations, it is conceivable to obtain plots from a problem of the Euler Lagrange equations. Finally, Euler totient function is graphically analyzed. We seek the following benefits: The association between Euler numbers and generating functions is more effectively understood, also the nature of the Euler constant and the Euler function  The Fourier transform is more comprehensible; also, it can be established that Matlab is an alternative way to study the conceptual development of achievements of physics and mathematics. We show that the abundance of Euler work and the history of mathematics, acquire better knowledge with the application of numerical tools","PeriodicalId":448231,"journal":{"name":"International Review of Physics","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115138152","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
