Fabrication of Tio2 crystalline coatings by combining Ti-6Al-4V anodic oxidation and heat treatments
(Hindawi Publishing Corporation, 2015-01)
The bio- and hemocompatibility of titanium alloys are due to the formation of a TiO2 layer. This natural oxide may have fissures which are detrimental to its properties. Anodic oxidation is used to obtain thicker films. ...
Giant Chemo-Resistance of SnO disk-like structures
(2013-07-03)
Single crystalline SnO micro-disks, synthesized by a carbothermal reduction process, exhibited a nearly 1000-fold increase in resistance upon exposure to 100 ppm of NO2 without addition of catalysts or dopants nor the ...
Annealing Effects On The Structural And Optical Properties Of Vanadium Oxide Film Obtained By The Hot-filament Metal Oxide Deposition Technique (hfmod)
(Rede Latino-Americana de Materiais, 2017)
EFFECT OF DUAL MODIFICATION OF BANANA STARCH AND STORAGE TIME ON THERMAL AND CRYSTALLINITY CHARACTERISTICS OF ITS FILMS.
(2013-02-19)
Banana starch was oxidized at three different levels and subsequently acetylated. This double modified banana starch was used for film preparation with the addition of glycerol. Thermal and crystallinity properties were ...
Morphology, crystalline structure and chemical composition of MAO treated Ti-15Zr-Mo surfaces enriched with bioactive ions
(2019-01-01)
In this study, MAO treatment was used to enrich, with bioactive Ca, Mg and P atoms, as-casted and heat-treated Ti-15Zr-xMo (x = 0, 5, 10 and 15 wt%) alloys, for potential use as advanced metallic biomaterials. The chemical ...
Synthesis of microporous/mesoporous core-shell materials with crystalline zeolitic shell and supported metal oxide silica core
(Royal Society of Chemistry, 2016-04)
An engineered material, possessing a hierarchical porosity in a shape selective manner, was synthesized by placing a microporous silicalite-1 shell over silica microspheres embedded with various guest species. Core materials ...
Novel Aspects of the Purpose-Built Materials Strategy: Evidence of Topographic Template Effect and Oriented Attachment Growth Mechanism
(Amer Scientific Publishers, 2008-07-01)
We report two novel aspects relating to the growth of oriented 3D arrays of SnO2 nanorods, based on the "purpose-built materials" (PBM) strategy. Under controlled conditions, the substrate acted as a topographic template ...
