Morphological, optical, and Raman characteristics of ZnO nanoflakes prepared via a sol-gel method
(WILEY-VCH Verlag GmbH & Co., 2012-01)
Two-dimensional (2D) ZnO nanoflakes were grown on thin aluminum layer, deposited on silicon substrate, using a sol-gel method. The surface morphologies of ZnO nanoflakes at different precursor concentrations were studied ...
Structural and optical investigations of cadmium sulfide nanostructures for optoelectronic applications
(Elsevier Ltd., 2012-11)
Cadmium sulfide (CdS) nanostructures were deposited on glass substrates by sol–gel spin coating technique. X-Ray Diffraction
(XRD) results have indicated that the formation of CdS has hexagonal structure. The lattice constants ...
Food assimilated by two sympatric populations of the brown planthopper Nilaparvata lugens (Delphacidae) feeding on different host plants contaminates insect DNA detected by RAPD-PCR analysis
(FUNPEC-RP - Fundação de Pesquisas Científicas de Ribeirão Preto, 2012-01)
Contamination of insect DNA for RAPD-PCR analysis can be a problem because many primers are non-specific and DNA from parasites or gut contents may be simultaneously extracted along with that of the insect. We measured the ...
Genetic dissection of sympatric populations of brown planthopper, Nilaparvata lugens (Stl), using DALP-PCR molecular markers
(Hindawi Publishing Corporation, 2012)
Direct amplified length polymorphism (DALP) combines the advantages of a high-resolution fingerprint method and also characterizing the genetic polymorphisms. This molecular method was also found to be useful in brown ...
Sensitivity of A-549 human lung cancer cells to nanoporous zinc oxide conjugated with Photofrin
(Springer-Verlag London Ltd., 2012-05)
In the present study, we demonstrated the use of nanoporous zinc oxide (ZnO NPs) in photodynamic therapy. The ZnO NPs structure possesses a high surface to volume ratio due to its porosity and ZnO NPs can be used as an ...
First-principles calculations of the structural, electronic and optical properties of cubic BxGa1−xAs alloys
(Elsevier B.V., 2012-04-15)
Density functional calculations are performed to study the structural, electronic and optical properties of technologically important BxGa1−xAs ternary alloys. The calculations are based on the total-energy calculations ...
A brief review of the current technologies used for the fabrication of metal-molecule-metal junction electrodes
(Scientific.Net, 2012-12)
Fabrication techniques for Metal-molecule-metal junction electrodes suitable to study electron tunneling through metal junctions are reviewed. The applications of current technologies such as mechanical break junction, ...
Gold nanoparticle sensor for the visual detection of pork adulteration in meatball formulation
(Hindawi Publishing Corporation, 2012)
We visually identify pork adulteration in beef and chicken meatball preparations using 20 nm gold nanoparticles (GNPs) as colorimetric sensors. Meatball is a popular food in certain Asian and European countries. Verification ...
Nanobioprobe for the determination of pork adulteration in burger formulations.
(Hindawi Publishing Corporation, 2012)
We report the development of a swine-specific hybrid nanobioprobe through a covalent integration of a fluorophore-labeled 27-nucleotide AluI-fragment of swine cytochrome b gene to a 3nm gold nanoparticle for the determination ...
