Growth and physical properties of highly oriented La-doped (K,Na)NbO3 ferroelectric thin films
(2015-02-27)
Article
Accés obertLead-free (K,Na)NbO3 (KNN) and La doped (K,Na)NbO3 (KNN-La) thin films are grown on SrTiO3 substrates using the chemical solution deposition method. The effect of adding different amounts of Na and K excess (0-20 mol%) is ... -
Effects of gravity level on bubble formation and rise in low-viscosity liquids
(2015-05-15)
Article
Accés obertWe present an experimental analysis of the effects of gravity level on the formation and rise dynamics of bubbles. Experiments were carried out with millimeter-diameter bubbles in the hypergravity environment provided by ... -
Mixing efficiency across Rayleigh-Taylor and Richtmeyer-Meshkov fronts
(World Scientific Publishing, 2015-06-03)
Article
Accés obertMixing generated by gravitational acceleration and the role of local turbulence measured through multifractal methods is examined in numerical experiments of Rayleigh-Taylor and Richtmyer-Meshkov driven front occurring ... -
An experimental-computer modeling study of inorganic phosphates surface adsorption on hydroxyapatite particles
(Royal Society of Chemistry, 2015-01-01)
Article
Accés obertThe adsorption of orthophosphate, pyrophosphate, triphosphate and a trisphosphonate onto hydroxyapatite has been examined using experiments and quantum mechanical calculations. Adsorption studies with FTIR and X-ray ... -
Dynamics of axially localized states in Taylor-Couette flows
(2015-05-15)
Article
Accés obertWe present numerical simulations of the flow confined in a wide gap Taylor-Couette system, with a rotating inner cylinder and variable length-to-gap aspect ratio. A complex experimental bifurcation scenario differing from ... -
Dynamics of shoreface-connected and inactive sand ridges on a shelf, Part 2: The role of sea level rise and associated changes in shelf geometry
(2015-08)
Article
Accés obertMany inner continental shelves are characterized by the presence of large rhythmic bedforms, such as shoreface-connected ridges and the more offshore located sand ridges, which have heights of several meters and are spaced ... -
Snow bands over the Gulf of Finland in wintertime
(2015-01-16)
Article
Accés obertLarge shore-parallel, quasi-stationary snow bands are occasionally observed over the Gulf of Finland during wintertime when the sea is not frozen. On the basis of Weather Research and Forecasting mesoscale model experiments ... -
Magnetoelectric response in (1-x)PbZr0.65Ti0.35O3-xBaFe(12)O(19) multiferroic ceramic composites
(2015-05-01)
Article
Accés obertThe magnetoelectric (ME) properties of PbZr0.65Ti0.35O3-BaFe12O19 (PZT-BaM) multiferroic ceramic composites have been investigated in this work. These materials, containing both the ferroelectric PZT and ferrimagnetic BaM ... -
Economically feasible energy refurbishment of prefabricated building in Belgrade, Serbia
(2015-07-01)
Article
Accés obertThe main objective of the presented paper was to evaluate the integrated design strategies applied in refurbishment of the prefabricated residential housing, erected in '70 in the New Belgrade, Serbia, in order to achieve ... -
Spiral instability can drive thermonuclear explosions in binary white dwarf mergers
(2015-02-10)
Article
Accés obertThermonuclear, or Type Ia supernovae (SNe Ia), originate from the explosion of carbon-oxygen white dwarfs, and serve as standardizable cosmological candles. However, despite their importance, the nature of the progenitor ... -
Cardiac contraction induces discordant alternans and localized block
(2015-02-04)
Article
Accés obertIn this paper we use a simplified model of cardiac excitation-contraction coupling to study the effect of tissue deformation on the dynamics of alternans, i.e., alternations in the duration of the cardiac action potential, ... -
Shape memory alloys as an effective tool to damp oscillations: study of the fundamental parameters required to guarantee technological applications
(2015-03-01)
Article
Accés obertThe SMA was studied for their macroscopic application in damping for civil engineering. The study is a synthesis and includes an outline of the models required for the SMA simulation and some case studies using the finite ...
