These X-rays were used for interaction process with the sample (Tamra bhasma) and incident and transmitted photons are collected by a NaI(Tl) scintillation X-ray detector. The mass attenuation coefficients values are determined by following all procedure such as counting times, background intensities, error involved in counting statistics and good geometry is maintained for the counting of photon beams. The experimentally obtained values are compared with the theoretically calculated values, using the WinXcom data program. From obtained results, it reveals that, the variation in percentage deviation (PD) of experimental and theoretical calculated values of mass attenuation coefficient corresponds to the amount of bioenhancers, incorporated in Tamra bhasma during preparation process. Here variation in percentage deviation reflects drugs as the admixture of elements other than the pharmaceutical active ingredients (here in Tamra bhasma Cu is the Active Pharmaceutical Ingredient) which focuses on the purity and also change in quality of medicines.

Ultraviolet-Visible spectroscopy, the characteristic Surface Plasmon Resonance (SPR) band placed at around 427 nm. FTIR analysis shows the formation of chemical bonding/conjugation between the Ag nanoparticles and PVA chains. X-ray diffraction analysis shows that Ag metal is present in face-centered cubic (fcc) crystal structure. The morphology of particles was studied using Field Emission Scanning Electron Microscopy (FESEM) it shows the nanoparticles are in spherical shape. The presence of Ag was confirmed using Energy Dispersive X-ray Spectroscopy (EDX) elemental analysis. Transmission Electron Microscopy (TEM) shows the particles were nano size and monodispersed. The antibacterial activities of the PVA/Ag nanocomposites were obtained using the zone inhibition method. The samples were tested against Gram-positive bacteria: Bacillus Subtilis, Staphylococcus aureus, and Gram-negative bacteria: Escherichia coli, Klebsiella pneumoniae. This study reveals that the irradiated PVA/Ag nanocomposites film shows good antibacterial activity against the Gram-positive and Gramnegative bacteria.","PeriodicalId":14348,"journal":{"name":"International Journal of Scientific Research in Physics and Applied Sciences","volume":"88 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76188115","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}

The structural and dielectric properties of the films were characterized by XPS, TEM, and impedance analyzer. The elemental composition and the oxidation state of the elements in the films were investigated by XPS, titanium peaks were observed at 458.67eV, 457.45eV and 457.28eV that belongs to Ti +4 . The presence of Fe +3 in the samples is indicated by peaks found at 717.9eV and 709.41eV (2p1/2 and 2p3/2) state and at 743eV TEM studies confirm mostly the crystallite anatase and rutile phase for the Fe doped TiO2 films. Particle size decreased from 35 nm to 17 nm by 10-mol % iron doping. The density of interfacial states decreases with increase in iron concentration. XPS studies reveal that titanium exists in Ti +4 state in all the samples. Dielectric conductivity increased with increase in Fe concentration.

The present theoretical approach uses microscopic theory as a tool to compute the detailed dynamical structure factor, current-current correlation function and hence, the diffusion coefficient as well as the coefficient of longitudinal viscosity. Microscopic theory uses interparticle-interaction present among particles of a liquid to yield density-density response function and hence, its complete dynamics. The diffusion coefficient is evolved as a realistic parameter which has been fit to explain the experimental dynamical structure factors. The coefficient of longitudinal viscosity on the other hand is directly related to static structure factor and diffusion coefficient in the regime where wavevector and frequency approaches zero. It also depends upon velocity of sound which, in the present communication, has been calculated from peak positions of current-current correlation functions in the limit wavevector approaches zero. Computed results for both of the transport coefficients, self diffusion coefficient and longitudinal viscosity are found to agree well with the corresponding experimentally reported values.","PeriodicalId":14348,"journal":{"name":"International Journal of Scientific Research in Physics and Applied Sciences","volume":"30 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75062841","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}
