Objective(s): Hardystonite (HT) has been successfully prepared by a modified sol-gel method. We hypothesized thatnano-sized (HT) would mimic more efficiently the nanocrystal structure and function of natural bone apatite, owing to the higher surface area, compare to conventional micron-size (HT).Materials and Methods: The hardystonite nanopowder was prepared via a modified sol-gel method.Optimi...

in this research, we reported a novel modified carbon ceramic electrode (cce) using ni/al layered double hydroxide as modifier was fabricated by sol-gel technique. the ni/al layered double hydroxide modified sol gel derived carbon ceramic (ni/al ldh-sgd-cc) electrode was used for electrocatalytic oxidation of acetaldehyde. the oxidation of acetaldehyde happens at the potential where ni (iii) sp...

A novel chemically modified electrode containing Prussian blue complex was achieved on the surface of glass carbon electrode by sol-gel technique. The electrochemical behavior of modified electrode was characterized by cyclic voltammetry in detail. The film electrode obtained was very stable and exhibited electrocatalytic response for oxidation of nitrite. Results showed at bare GC electrode, a...

Hydrothermally and sol-gel-synthesized immobilized surfactant-modified polyaniline-carbon nanotubes/TiO₂ (PANi-CNT/TiO₂) photocatalysts were prepared and their application in the degradation of diethyl phthalate (DEP) under visible light at 410 nm was investigated in this sturdy. To improve the dispersion of nanoparticles and the transfer of electrons, the TiO₂ surface was modified with both so...

in this work, sol-gel method was used tosynthesize titanium dioxide nanoparticles (tio2). the tio2nanoparticles was characterized by scanning electron microscopy (sem), x-ray diffraction (xrd) and bet technique.the tio2 and coumarin derivative (7-(1,3-dithiolan-2-yl)-9, 10-dihydroxy-6h-benzofuro [3,2-c] chromen-6-on) were incorporated in a graphite composite electrode. the resulting modified el...

This article provides details of a study that investigates hydrogen (H2) separation, purification and transport behaviour ceramic ?-alumina membrane compares it with ?-alumina modified Boehmite sol.

INTRODUCTION The aim of this study was to assess the usefulness of 4 clinical prediction rules, the neuroimaging guidelines from the Canadian Consensus Conference on Dementia (CCCAD) and the modified Hachinski's Ischaemic Score (HIS) in identifying patients with suspected dementia who will benefit from neuroimaging. MATERIALS AND METHODS Two hundred and ten consecutive patients were referred ...

in this paper, labo3 perovskite type catalyst formulations were prepared by sol-gel auto combustion method using citric acid as the fuel. activity of catalysts was tested in catalytic oxidation of toluene as a model of volatile organic compounds. lacoo3 perovskite formulation showed the highest activity among labo3 (fe, mn and co) perovskite catalysts. so, lacoo3 perovskite based catalyst was s...

The role of iron in two modes of integration into alumina catalysts was studied at 0.39 wt% Fe and tested in trichloroethylene combustion. One modified alumina was synthesized using the sol-gel method with Fe added in situ during hydrolysis; another modification was performed using calcined alumina, prepared using the sol-gel method and impregnated with Fe. Several characterization techniques w...
