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 ...
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 ...
Application of Morse potential in nonlinear dynamics of microtubules
(Nonlinear Dynamics, 2017)
We here present a model of nonlinear dynamics of microtubules using modified extended tanh-function method as a mathematical tool. Interaction between neighbouring dimers belonging to a single protofilament is commonly ...
The influence of architecture of nanoparticle networks on collective charge transport revealed by the fractal time series and topology of phase space manifolds
(Journal of Coupled Systems and Multiscale Dynamics, 2016)
Charge transport in the Coulomb blockade regime of two-dimensional nanoparticle arrays exhibits nonlinear I-V characteristics, where the level of nonlinearity strongly associates with the arrays architecture. Here, we use ...
Effect of gamma-irradiation on the hydrolytic stability and thermo-oxidative behavior of bio/inorganic modified urea-formaldehyde resins
(Composites: Part B: Engineering, 2015)
In order to minimize emission of formaldehyde from urea formaldehyde resins (UF) and to improve their thermo-oxidative behavior, the effect of low gamma-irradiation on hydrolytic and thermo-oxidative stability of nano-silica ...
