Calculations of Molecular Structures and Processes Important for Hydrogen Behaviour in the Li-Amide/Imide System
(Acta Physica Polonica A, 2011)
Lithium amide (LiNH(2)) and imide (Li(2)NH) have recently attracted much attention as part of the Li-H-N system suitable for hydrogen (H) storage applications. However, the ground-state imide structure is still unknown ...
Samarium-Doped Ceria Nanostructured Thin Films Grown on FTO Glass by Electrodepostion
(Acta Physica Polonica A, 2011)
Electrical, optical or catalytic properties of ceria can be tuned via doping by rare earth elements. The innate properties of ceria-based materials can be further amplified by using nanostructured ceria. In this study, ...
The Influence of Boron Doping Concentration on MgH2 Electronic Structure
(Acta Physica Polonica A, 2011)
We have performed ab initio electronic structure calculations of Mg1-xBxH2 compounds with different boron concentrations, ranging from x =0.0625 to 0.5. Full structural relaxation was performed in order to properly describe ...
LaYO3:Sm3+ Nanocrystalline Phosphor: Preparation and Emission Properties
(Acta Physica Polonica A, 2011)
Samarium doped LaYO3 nanocrystalline phosphor powders are obtained by polymer complex solution method. Stoichiometric quantities of La2O3, Y2O3 and for dopant ions Sm2O3 were dissolved in hot nitric acid. Polyethylene ...
Characterization of New Structure for Silicon Carbide X-Ray Detector by Method Monte Carlo
(Acta Physica Polonica A, 2011)
This work presents a characterization of radiation absorption properties of silicon carbide (SiC) as semiconductor for the realization of detectors for X-rays. SiC detectors can potentially reach superior performance with ...
Structural and Electrical Properties of Sintered Barium-Zinc-Titanate Ceramics
(Acta Physica Polonica A, 2011)
The aim of this work was an investigation of structural and electrical properties of sintered barium-zinc-titanate ceramics. Mixtures of BaCO(3), ZnO and TiO(2) were mechanically activated in a planetary ball mill up to ...
Swelling, Mechanical and Antimicrobial Studies of Ag/P(HEMA/IA)/PVP Semi-IPN Hybrid Hydrogels
(Acta Physica Polonica A, 2011)
A simple and fast approach to the design and production of new hybrid polymeric biomaterials with silver particles is presented in this work. Silver/semi-interpenetrating network hybrid hydrogels (Ag/semi-IPNHHs) were ...
Inter-Landau Level Scattering Processes in Magnetic Field Assisted THz Quantum Cascade Laser
(Acta Physica Polonica A, 2011)
We present a detailed analysis of GaAs/AlGaAs terahertz quantum cascade laser in the presence of an intense external magnetic field. One of the objectives in further development of THz quantum cascade laser is the realization ...
Magnetic Properties of Mn-Doped Amorphous SiO2 Matrix
(Acta Physica Polonica A, 2011)
Samples of Mn-doped amorphous SiO2 matrix with manganese concentration 0.7 and 3 at.% have been prepared by a sol-gel method. Transmission electron microscopy analysis has shown that the samples contain agglomerates of ...
Carbon Monolith Surface Chemistry Influence on the Silver Deposit Amount and Crystallite Size
(Acta Physica Polonica A, 2011)
The surface of carbon monolith (CM) was chemically treated in order to obtain antibacterial filters with silver deposit for water treatment. The chemical treatment involved submerging the as-received CM in HNO(3), KOH and ...
