Densification behaviour of nano-size CeO2
(Materials Science Forum, 2007)
A nano-sized CeO2 powder was synthesized by a modified glycine nitrate process (MGNP). The synthesized powder was characterized by X-ray diffraction (XRD), the Brunauer Emmett Teller (BET) method, and transmission electron ...
XRD analysis of calcium phosphate and biocomposite calcium phosphate/bioresorbable polymer
(Materials Science Forum, 2006)
Composite biomaterials based on calcium phosphate ceramic due to their high bioactivity are of interest for biological application and bone tissue repair. Structural and microstructural parameters of inorganic constituent ...
Comparison between different LiFePO4 synthesis routes
(Materials Science Forum, 2007)
Olivine-type lithium iron phosphate (LiFePO4) powders were synthesized applying three different methods: solid state reaction at high temperature, ultrasonic spray pyrolysis, and sonochemical treatment. The samples were ...
Nano-structured TiN thin films deposited by single ion beam reactive sputtering
(Materials Science Forum, 2007)
The reactive sputter deposition of TiN thin films onto glass substrate at the ambient temperature using a homemade broad beam argon ion source was investigated in order to deposit the films with nanostructural characteristics. ...
Phase composition and magnetic properties of multiphase melt-spun Nd4.3Fe76.2B19.5 alloy
(Materials Science Forum, 2007)
Phase transformations and magnetic properties of multiphase Nd4.3Fe76.2B19.5 alloy were investigated in the temperature range of heat treatment 600-700 degrees C. The influence of different heat treatment regimes was ...
Micromechanical analysis of constraint effect on fracture initiation in strength mismatched welded
(Materials Science Forum, 2007)
In this paper the micromechanical approach to ductile fracture was applied in a study of constraint effect on crack growth initiation in mismatched welded joints. The single-edged notched bend specimens (precrack length ...
Synthesis of pure and doped LaMnO3 powders from citrate precursors
(Materials Science Forum, 2007)
In this work pure and doped LMO were prepared using modified Pechini method from lanthanum and manganese citrates. Lanthanum citrate was prepared starting from La2O3, while manganese citrate was prepared from Mn(NO3)(2). ...
Experimental and theoretical investigation of hydrogen storage in magnesium based composites
(Materials Science Forum, 2007)
Magnesium based composites MgH2 + X (X=Ti, Co) were synthesized by ball milling in an argon atmosphere using stainless steel vial and balls. The crystallographic behavior of the resulting powders was examined by XRD. Thermal ...
Characterization of target material for x-ray generator by Monte Carlo method
(Materials Science Forum, 2007)
The adequate choice of different target materials for X-ray generators is a very important subject of engineers practice and research. In the present work we analyze theoretically the transport of electrons through the ...
Release and diffusion studies of hydrogels based on itaconic acid
(Materials Science Forum, 2007)
Controlled release studies of drugs (theophylline (TH), fenethylline hydrochloride (FE) and gentamicin sulphate (GS)) from pH sensitive poly(2-hydroxyethyl methacrylate/itaconic acid) (P(HEMA/IA)) hydrogels obtained by ...
