Characterization of BaTi1-xZrxO3 thin films obtained by a soft chemical spin-coating technique
(American Institute of Physics (AIP), 2004-10-15)
Single-phase perovskite structure BaZrxTi1-xO3 (BZT) (0.05less than or equal toxless than or equal to0.25) thin films were deposited on Pt-Ti-SiO2-Si substrates by the spin-coating technique. The structural modifications ...
Influence of Ca concentration on the electric, morphological, and structural properties of (Pb,Ca)TiO3 thin films
(American Institute of Physics (AIP), 2002-05-15)
Pb1-xCaxTiO3 (0.10less than or equal toxless than or equal to0.40) thin films on Pt/Ti/SiO2/Si(100) substrates were prepared by the soft solution process and their characteristics were investigated as a function of the ...

Structural refinement, optical and electrical properties of [Ba1-x Sm-2x/3](Zr0.05Ti0.95)O-3 ceramics
(Springer, 2014-08-01)
Samarium doped barium zirconate titanate ceramics with general formula [Ba1-x Sm-2x/3](Zr0.05Ti0.95)O-3 [x = 0, 0.01, 0.02, and 0.03] were prepared by high energy ball milling method. X-ray diffraction patterns and micro-Raman ...
Solid state NMR as a new approach for the structural characterization of rare-earth doped lead lanthanum zirconate titanate laser ceramics
(ELSEVIER SCIENCE BV, 2008)
To facilitate the design of laser host materials with optimized emission properties, detailed structural information at the atomic level is essential, regarding the local bonding environment of the active ions (distribution ...
Influence of spanwise twisting and bending on lift generation in MAV-like flapping wings
(American Society of Civil Engineers, 2017-01)
A numerical-simulation tool is developed that is well suited for modeling the unsteady and nonlinear aerodynamics of flying insects and small birds as well as biologically inspired flapping-wing micro air vehicles (MAVs). ...
