Effect of thickness on optical properties of nickel vertical posts deposited by GLAD technique
(Optical Materials, 2016)
Nickel (Ni) thin films of different thicknesses (25 nm to 150 nm) were deposited on glass substrates using Glancing Angle Deposition technique. Characterization of obtained Ni films was performed by scanning electron ...
Pyrolysis of pine and beech wood under isothermal conditions: the conventional kinetic approach
(Research on Chemical Intermediates, 2015)
Pyrolysis of pine and beech wood was investigated by isothermal thermogravimetry at five different temperatures (280, 290, 300, 310, and 320 A degrees C) in an atmosphere of flowing nitrogen. It was found that isothermal ...
Kinks and bell-type solitons in microtubules
(Chaos, 2016)
In the present paper, we study the nonlinear dynamics of microtubules relying on the known u-model. As a mathematical procedure, we use the simplest equation method. We recover some solutions obtained earlier using less ...
Assessment of the impact of geographical factors on the spatial distribution of heavy metals in soils around the steel production facility in Smederevo (Serbia)
(Journal of Cleaner Production, 2014)
The concentration of heavy metals (Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb and Zn) in surface soils in the area surrounding the steel production facility in Serbia was determined to assess the contribution of emissions to pollution. ...
Variation of indoor radon concentration and ambient dose equivalent rate in different outdoor and indoor environments
(Springer, 2016)
Subject of this study is an investigation of the variations of indoor radon concentration and ambient dose equivalent rate in outdoor and indoor environments of 40 dwellings, 31 elementary schools and five kindergartens. ...
The effect of gamma irradiation in air and inert atmosphere on structure and properties of unfilled or glass fibre-reinforced polyamide 6
(Springer, 2016)
Crosslinking of polyamide 6 (PA) and filled one with glass fibres (PA/GF) was initiated via macroradical formation by gamma irradiation either in air or in inert argon atmosphere. The crosslinked portion was found to start ...
Entropic nonextensivity as a measure of time series complexity
(Physica A: Statistical Mechanics and Its Applications, 2004)
Information entropy is applied to the analysis of time series generated by dynamical systems. Complexity of a temporal or spatio-temporal signal is defined as the difference between the sum of entropies of the local linear ...
Constraining the range of Yukawa gravity interaction from S2 star orbits II: bounds on graviton mass
(Journal of Cosmology and Astroparticle Physics, 2016)
Recently LIGO collaboration discovered gravitational waves [1] predicted 100 years ago by A. Einstein. Moreover, in the key paper reporting about the discovery, the joint LIGO and VIRGO team presented an upper limit on ...
Nickel film orientation change by nitrogen ion bombardment during deposition
(Vacuum, 1997)
The influence of nitrogen ion bombardment during e-beam triode ion plating of nickel on the microstructure and film orientation has been investigated. The deposition variables explored were the ion current density and ...
Measurement of thermal diffusivity of thin films by the AC calorimetric method
(High Temperatures: High Pressures, 1998)
Materials in the form of thin films are increasingly used in electronics and industry. In order to gain full control over fabricated thin-film ultimate properties, methods for their thermal characterisation are necessary. ...
