Effects of reaction time on the morphological, structural, and gas sensing properties of ZnO nanostructures
(Elsevier, 2014-02)
Morphological transformation was achieved from ZnO hexagonal needle-like rods to hexagonal flower-like rods by varying the reaction growth time using the hydrothermal method. Optical bandgap energies were calculated from ...
Influence of shear strength on long term biased humidity reliability of Cu ball bonds
(Springer Science+Business Media New York, 2014-10)
This paper compares and discusses the influence of shear strength (in terms of shear-per mils-square) of Au and Cu ball bonds on the biased humidity reliability performance in SOIC 8LD leaded package. Biased (HAST) highly ...
Design and analysis of various microcantilever shapes for MEMS based sensing
(Institute of Physics Publishing, 2014)
One the major requirements for sensing devices is its sensitivity. This paper presents the design, analysis and simulation of various types of MEMS based microcantilevers shapes and their influence on sensing sensitivity. ...
Structural properties of PbI₂ thin film
(Trans Tech Publications, 2014-01)
Lead iodide (PbI₂) thin films were successfully prepared by thermal evaporation method on a glass substrate at room temperature. The structural analysis of these films was done by XRD. The results revealed that the crystallite ...
Morphological, structural, and gas-sensing characterization of tin-doped indium oxide nanoparticles
(Elsevier, 2014-01)
Tin-doped indium oxide (ITO) nanoparticles with stable cubic phases were synthesized using a sol–gel combustion method that includes gelation and combustion in organic fuel. The influence of SnO₂ on the phase and morphology ...
Effect of different solvents on the structural and optical properties of zinc oxide thin films for optoelectronic applications
(Elsevier, 2014-01)
Zinc oxide (ZnO) seed solutions were prepared using 4 different solvents, namely, methanol (MeOH), ethanol (EtOH), isopropyl alcohol (IPA) and 2-methoxyethanol (2-ME). The prepared seed solutions were used to synthesize ...
A simple one-step anodising method for the synthesis of ordered porous anodic alumina
(Taylor & Francis, 2014)
Porous anodic alumina (PAA) has been produced on aluminium substrate by single-step anodising at 50 V in 0.3 M oxalic acid at 15°C for 60 min. The highly ordered pore and cell structure was achieved by subjecting the PAA ...
Application of gold nanoparticles for electrochemical DNA biosensor
(Hindawi Publishing Corporation, 2014)
An electrochemical DNA biosensor was successfully fabricated by using (3-aminopropyl)triethoxysilane (APTES) as a linker molecule combined with the gold nanoparticles (GNPs) on thermally oxidized SiOthin films. The SiOthin ...
