Currently, numerous properties of semiconducting oxides are correlated to their morphological characteristics resulting from exposed surfaces. In the present work, relationship between following morphologies rod, bean, hexagon, and rod/cube CeO2 with exposure (111), (110), (100), (311) surfaces main charge carriers generated by photochemical processes was investigated. This done in regard degradation ciprofloxacin rhodamine-B. The initial stages two types molecules were evaluated, allowing...
Microwave assisted hydrothermal (MAH) method was used to synthesize crystalline bismuth ferrite (BiFeO3) nanoparticles (BFO) at temperature of 180?C with times ranging from 5 min 1 h. For comparison, BFO powders were also crystallized by the soft chemistry route in a conventional furnace 850?C for 4 X-ray diffraction (XRD) results verified formation perovskite crystallites while infrared data showed no traces carbonate. Field emission scanning microcopy (FE/SEM) revealed homogeneous size...
The use of perovskite-based materials and their derivatives can have an important role in the heterogeneous catalytic field based on photochemical processes. Photochemical reactions a great potential to solve environmental damage issues. presence precious metals perovskite structure (i.e., Ag, Au, or Pt) may improve its efficiency significantly. metal comprise lattice as well form heterostructure with it. is directly related processing conditions. Based this, this review will address...
Here we combined experimental and theoretical results to correlate the morphological, optical, electronic properties of cerium oxide (CeO2) prepared by a microwave-assisted hydrothermal method with varying synthesis times. X-ray diffraction confirmed cubic structure without deleterious phases. Density functional theory simulations an indirect (K-L) bandgap energy 2.80 eV, electron transition between O-2p Ce-4f orbitals, which agrees value obtained using diffuse reflectance. Raman...
This study was aimed at investigating the in vitro biocompatibility of a novel membrane composite poly(vinylidene-trifluoroethylene)/barium titanate (P(VDF-TrFE)/BT). Osteoblastic cells were obtained from human alveolar bone fragments and cultured under standard osteogenic condition until subconfluence. First passaged on P(VDF-TrFE)/BT expanded polytetrafluoroethylene (e-PTFE--control) membranes 24-well plates. Cell adhesion spreading evaluated 30 min, 4 24 h. For proliferation assay, for 1,...
This paper presents a portable laboratory platform (PLP) with electrochemical amperometric biosensors for the detection of hepatitis C virus (HCV). PLP is composed by controller unit, Bluetooth module to provide communication mobile devices, and potentiostat circuit perform cyclic voltammetry. The allows devices set up parameters, e.g., cycling voltage in range ±1.5 V, scan rate 5-1000 mV <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">-1</sup>...
In this paper a piezoelectric composite membranes were developed for charge generator to promoter bone regeneration on defects sites. Is known that the osteogenesis process is induced by interactions between biological mechanisms and electrical phenomena. The prepared mixing Barium Titanate (BT) powders PVDF-TrFE (PVDF:TrFE = 60:40 mol%) dimethylformamide medium. This precursor solution was dried crystallized at 100oC 12 hours. Composites obtained following methods: solvent casting (SC),...
