Effect of Zn and Ni substitution on structural, morphological and magnetic properties of tin oxide nanoparticles
(
Elsevier
, 2016 , Article)
Structural, morphological, optical and magnetic properties of Zn and Zn–Ni co-doped tin oxide (SnO2) nanoparticles synthesized by sol-gel method. The influence of doping concentration on phase and particle size of the ...
Spinel ferrite nanoparticles for H2S gas sensor
(
Springer Verlag
, 2017 , Article)
We investigate H2S gas sensors based on spinel ferrite CuFe2O4 nanoparticles prepared by the co-precipitation method. This technique is an efficient and fast technique to produce nanoparticles. Furthermore, those nanoparticles ...
Fabrication and characterization of flexible ruthenium oxide-loaded polyaniline/poly(vinyl alcohol) nanofibers
(
Wiley
, 2020 , Article)
© 2020 Wiley Periodicals, Inc. Polyaniline/poly(vinyl alcohol)/ruthenium oxide (RuO2) composite nanofibers were produced by electrospinning technique. Hydrous ruthenium chloride was used as a precursor at different ...
Fabrication and characterization of poly(vinyl alcohol)-Glycerol-Spinel ferrites flexible membranes
(
John Wiley and Sons Inc.
, 2019 , Article)
Polymer membranes of ferrites nanoparticles, glycerol, and poly(vinyl alcohol) (PVA) were fabricated using a solution casting method. Spinel ferrites nanoparticles, CuFe2O4 or ZnFe2O4, and glycerol were used as dopants to ...
Linear hydrogen gas sensors based on bimetallic nanoclusters
(
Elsevier Ltd
, 2016 , Article)
This work reports on the fabrication of hydrogen gas sensors based on bimetallic palladium-copper nanoclusters. The nanoclusters were generated by sputtering and inert-gas condensation inside an ultra-high vacuum (UHV) ...
Investigation of phase transformation for ferrite-austenite structure in stainless steel thin films
(
Elsevier B.V.
, 2016 , Article)
In this work we report on phase transformation of 304 stainless steel thin films due to heat treatment. Ex-situ annealing was applied for evaporated 304 stainless steel thin films inside an ultra-high vacuum chamber with ...
Structural evaluation, preliminary in vitro stability and electrochemical behavior of apatite coatings on Ti6Al4V substrates
(
Elsevier Ltd
, 2016 , Article)
Medical-grade alloys, such as Ti-6Al-4V, have been used for fixation of fractured bone and for the total replacement of defective bone. Their bioactivity could be improved by applying a bone-like apatite layer onto their ...
Selective H2S sensor based on CuO nanoparticles embedded in organic membranes
(
Elsevier B.V.
, 2016 , Article)
We report on H2S gas sensors based on CuO nanoparticles that are embedded within polymer membranes of poly-vinyl-alcohol (PVA) and glycerol ionic liquid (IL). The nanoparticles were fabricated by the colloid microwave ...
Production of metal-oxide nanoclusters using inert-gas condensation technique
(
Elsevier B.V.
, 2017 , Article)
Inert-gas condensation is a novel technique that can be used to produce nanoclusters for different applications. In the present work, dc sputtering combined with inert-gas condensation were used to produce copper oxide ...
Characterization of H2S gas sensor based on CuFe2O4nanoparticles
(
Elsevier Ltd
, 2017 , Article)
Copper ferrite (CuFe2O4) nanoparticles were prepared by the sol-gel auto-combustion method and used to construct a conductometric gas sensor in this work. The as-prepared CuFe2O4 nanoparticles were annealed at 500 °C and ...
