Electrodic surfaces of natural chalcopyrite and pyrite minerals (El Teniente mine, Chile) have been studied by cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS), X-ray photoelectron (XPS), scanning electron microscopy including microanalysis (SEM/EDX). For comparison, fractured polished mineral were also XPS. In both electrodes, the formation Fe(III) species containing oxygen detected Cu(II) additionally for at advanced oxidation states. The presence was not XPS initial...

We present a simple technique for the calibration, prediction, and optimization of optical modulation properties liquid-crystal display (LCD). The method is useful when there no information about internal fabrication parameters device (the orientation molecules, twist angle, or birefringence material). A complete determination LCD Jones matrix accomplished by means seven irradiance measurements single wavelength. This only requires two linear polarizers one quarter-wave plate. Once has been...

In a previous study, new ceramic material (Bioeutectic ® ), prepared by slow solidification through the eutectic temperature‐composition region of wollastonite–tricalcium phosphate system, was found to be bioactive in static‐simulated body fluid. The reacts dissolving pseudowollastonite phase and forming hydroxyapatite‐like porous structure pseudomorphic transformation tricalcium lamellae, which turn mimics bone. Later, layer is formed precipitation on surface material. present bioactivity...

Abstract This study reports on the in vitro and vivo behavior of α‐tricalcium phosphate (αTCP) also αTCP doped with either 1.5 or 3.0 wt % dicalcium silicate (C 2 S). The ceramics were successfully prepared by powder metallurgy method combined homogenization heat treatment procedures. All materials composed a single‐phase, case pure material, solid solution C S for αTCP, which stable at room temperature. tested bioactivity simulated body fluid, cell culture medium containing adult...

Silicon ( Si ) influences the biologic activity of calcium phosphate materials by modifying material properties and direct effects on physiological processes in skeletal tissue. Compositions belonging to system dicalcium silicate (Ca 2 SiO 4 = C S )‐tricalcium Ca 3 (PO TCP), able release that element situ , are promising candidates for preparing new ceramic bone implants. An exact knowledge phase relationships is required design with controlled compositions properties. Thus, a study...

In this work, conditions of Suzuki condensation and polymer modification polymers benzene fluorene units have been studied. A new was prepared with statistical equimolecular amounts two 2,7-dibromo-9,9-bis(6'-susbtituted-hexyl)fluorene as starting monomers. The C9 position the poly[9,9-bis(6'-bromohexylfluoren-2,7-diyl)-alt-co-(benzen-1,4-diyl has substituted yielding poly[9,9-bis(6'-cyanohexylfluoren-2,7-diyl)-alt-co-(benzen-1,4-diyl)] a high degree conversion. All were completely soluble...

This research examines the biological behavior of multilayer ceramic-glass scaffolds for bone tissue engineering. The consist a high-strength core wollastonite and P6 (Ca2P6O17), with sequential coating TCP doped Na+, K+ Mg2+ ions to confer bioactivity system. Two formulations were investigated: magnesium-deficient one, which served as microstructure control, magnesium-rich one in hollow hydroxyapatite (HA) spheres precipitated after week immersion simulated body fluid (SBF). These are...

We discuss a simple method for fabricating interference birefringent filters using common cellophane tape layers. Cellophane layers can be superimposed with different orientations to generate spectral responses. demonstrate this behavior portable spectrophotometer. This technique is and inexpensive way of investigating the optical properties filters.

In the present work, we modified surface morphology of 3D porous ceramic scaffolds by incorporating strontium phosphate (SrP) hollow nano-/microspheres with potential application as delivery system for local release therapeutic substances. SrP spheres were synthesized a template-free hydrothermal method. The influence reaction temperature, time and concentration reactants on precipitates' size investigated. To obtain larger number open spheres, new methodology was developed consisting...
