Anelastic relaxation due to hydrogen in Ti-35Nb-7Zr-5Ta alloy
(Materials Science and Engineering A: Structural Materials Properties Microstructure and Processing, 2011-04-15) [Artigo]
Titanium and its alloys are frequently used in the production of prostheses and dental implants due to their properties, such as high corrosion resistance, low elasticity modulus, and high mechanical strength/density ...
Dynamical Elastic Moduli of the Ti-13Nb-13Zr biomaterial alloy by mechanical spectroscopy
(Materials Research, 2012-12-01) [Artigo]
Dynamical Elastic Moduli of the Ti-13Nb-13Zr biomaterial alloy were obtained using the mechanical spectroscopy technique. The sample with heat treatment at 1170K for 30 minutes and water quenched with subsequent aging ...
In Vitro Cytotoxicity of a Ti-35Nb-7Zr-5Ta Alloy Doped with Different Oxygen Contents
(Materials, 2014-03-01) [Artigo]
Cp-Ti is the most common material used for dental implants, but its elastic modulus is around five times higher than that of bone. Recently, promising alloys that add Nb, Ta, Zr and Mo to Ti have been developed. The ...
A simple derivation of the Lindblad equation
(Revista Brasileira de Ensino de Física, 2013-03-01) [Artigo]
We present a derivation of the Lindblad equation - an important tool for the treatment of nonunitary evo- lutions - that is accessible to undergraduate students in physics or mathematics with a basic background on quantum ...
Rare earth centers properties and electron trapping in SnO2 thin films produced by sol-gel route
(Journal of Non-Crystalline Solids, 2008-11-01) [Artigo]
Some very relevant optical. electrical, and structural properties of SnO2 doped with rare-earth ions Er3+ and Eu3+ are presented. Films are produced by the sol-gel-clip coating process, and may be described as a combination ...
Synthesis and characterization of mono and polymeric cyclopalladated compounds: Crystal and molecular structure of [{Pd(dmba)(ONO2)}(2)(mu-pz)] center dot H2O (pz = pyrazine)
(Polyhedron, 2009-02-03) [Artigo]
In the treatment of cyclometallated dimer [Pd(dmba)(mu-Cl)](2) (dmba = N,N-dimethylbenzylamine) with AgNO3 and acetonitrile the result was the monomeric cationic precursor [Pd(dmba)(NCMe)(2)](NO3) (NCMe=acetonitrile) (1). ...
Structural, microstructural, optical and electrical properties of (Pb,Ba,Sr)TiO3 films growth on conductive LaNiO3-coated LaAO(3)(100) and Pt/Ti/SiO2/Si substrates
(Materials Letters, 2014-04-15) [Artigo]
The ferroelectric and dielectric properties of lead barium strontium titanate (PBST) thin films are investigated on different bottom electrode and substrate such as Pt, LaNiO3 and Pt/Ti/SiO2/Si, LaAlO3(100), respectively. ...
SVET, SKP and EIS study of the corrosion behaviour of high strength Al and Al-Li alloys used in aircraft fabrication
(Corrosion Science, 2014-07-01) [Artigo]
The 2XXX and 7XXX series aluminium alloys are commonly used in aircraft applications where high strength-to-weight ratios are required. The present study aims to compare the corrosion resistance of two novel alloys developed ...
Protonation Pattern, Tautomerism, Conformerism, and Physicochemical Analysis in New Crystal Forms of the Antibiotic Doxycycline
(Crystal Growth & Design, 2014-08-01) [Artigo]
Doxycycline (DOX) is a tetracycline class drug that is used worldwide as a broad-spectrum antibiotic. Although its clinical importance and use have been known since the 1960s, only four crystal forms have been reported ...
Natural rubber latex used as drug delivery system in guided bone regeneration (GBR)
(Materials Research, 2009-06-01) [Artigo]
In this work, we propose natural rubber latex (NRL) membranes as a protein delivery system. For this purpose Bovine Serum Albumin (BSA) was incorporated into the latex solution for in vitro protein delivery experiments. ...
