Influence of vanadium on electrical and microstructural properties of CaCu3Ti4O12/CaTiO3
(Elsevier B.V. Sa, 2010-05-14)
Microstructure, electrical properties and dielectric behavior of undoped and VO2-doped CaCu3Ti4O12/CaTiO3 (CCTO/CTO) systems, were investigated. Discs doped with 0-3 mol% of VO2 were sintered at 1075 degrees C CaTiO3 (CTO) ...
Synthesis and anti-Mycobacterium tuberculosis activity of vanadium complexes with N,N,O-donor ligands
(John Libbey Eurotext, 2008-01-01)
Oxovanadium(IV) and dioxovanadium(V) complexes with Schiff base derivatives have been prepared, characterized and their in vitro antibacterial activities were evaluated against the Mycobacterium tuberculosis H37Rv ATCC ...
Effect of iron and vanadium on the phase transition of titanium dioxide obtained by polymeric precursor method
(2017-01-01)
The titanium dioxide phase formation is dependent on the synthesis method, temperature of calcination and modifiers insertion. By using chemical methods, such as Polymeric Precursor Method, the organic impurities or extrinsic ...
Crystallographic structure of Ti-6Al-4V, Ti-HP and Ti-CP under high-pressure
(2010-05-11)
The phase stability of a commercial purity (Ti-CP), high purity (Ti-HP) and Ti-6Al-4V alloy were investigated in a diamond anvil cell up to 32 GPa and 298 K using a polychromatic X-ray beam. The Ti-CP and Ti-HP shown the ...

The influence of heat treatment on the structure and microstructure of ti-15Mo-xNb system alloys for biomedical applications
(2014-01-01)
The Ti-15Mo-xNb system integrates a new class of titanium alloys without the presence of aluminum and vanadium, which exhibit cytotoxicity, and that have low elasticity modulus values (below 100 GPa). This occurs because ...
Preparation and characterization of Ti-10Mo-xZr alloys for biomedical applications
(2016-01-01)
Titanium alloys are constantly being studied for possible applications as biomaterials. However, studies suggest that aluminum and vanadium, when used in the human body over long period of time, are associated with adverse ...
