The influence of different species of gases on the luminescent and structural properties of pulsed laser-ablated Y2O2S:Eu3+ thin films.
(Springer., 2016-04)
Y2O2S:Eu3+ films have been grown on Si (100) substrates by using a pulsed laser deposition technique. The thin films grown under vacuum, argon and oxygen ambient have been characterized using structural and luminescent ...
A STUDY OF A HYDRO MAGNETIC FLUID FLOW IN A ROTATING SYSTEM BOUNDED BY TWO PARALLEL PLATES
(Jomo Kenyatta University of Agriculture and Technology, 2013)
An electrically conducting fluid flowing between two parallel plates has been considered in this study. The fluid flow is unsteady and a magnetic field is applied perpendicular to the plates. Various configurations have ...
Stability of phytochemicals as sources of anti-inflammatory nutraceuticals in beverages—A review
(Elsevier, 2013)
Recently phytochemical constituents have attracted a lot of interest as sources of functional ingredients in food product formulations. However, before being incorporated into foods or beverages the stability of these ...
Synthesis, characterization and crystal structures of two polymorphs of the iodo-bridged ruthenium salt, μ-iodido-bis {η 5-cyclopentadienyl-dicarbonyl-ruthenium (II)} tetrafluoroborate
(Elsevier, 2013)
The reaction of RpI (Rp = (η5-C5H5)Ru(CO)2) and AgBF4 in two different solvents, tetrahydrofuran and dichloromethane afforded two polymorphs of the iodo-bridged cationic complex [Rp2I]BF4. Polymorph I precipitates out of ...
Optical properties of ZnO nanoparticles synthesized by varying the sodium hydroxide to zinc acetate molar ratios using a Sol-Gel process.
(Springer, 2016)
Material property dependence on the OH−/Zn2+ molar ratio of the precursor was investigated by varying the amount of NaOH during synthesis of ZnO. It was necessary to control the water content and temperature of the mixture ...
Effect of Selected Metal Ions on the Mycelial Growth of Sclerotinia Sclerotiorum Isolated From Soybean Field in Rongai, Kenya
(International Journal of Chemistry and Materials Research, 2014)
White mold caused by Sclerotinia sclerotiorum attacks a wide host range of broad-leafed plants which includes soybeans. The effect of twelve metal ions (Hg+2, Co+3, Ag+1, La+3, Cd+2, Cr+3, Cu+2, Zn+2, Mo+5, Sr+2, Sn+4 and ...
The influence of oxygen partial pressure on material properties of Eu3+-doped Y2O2S thin film deposited by Pulsed Laser Deposition.
(Elsevier B.V., 2015)
Eu3+-doping has been of interest to improve the luminescent characteristics of thin-film phosphors. Y2O2S:Eu3+ films have been grown on Si (100) substrates by using a Pulsed Laser Deposition technique.The thin films grown ...
Effect of Mn doping on the structural and optical properties of sol-gel derived ZnO nanoparticles.
(Springer, 2011)
Un-doped and Mn-doped ZnO nanoparticles were successfully synthesized in an ethanolic solution by using a sol-gel method. Material properties of the samples dependence on preparation conditions and Mn concentrations were ...
Synthesis, characterization and structural elucidation of water-soluble 1-aminoalkane and α,ω-diaminoalkane complexes of the pentamethylcyclopentadienyliron dicarbonyl cation, [Cp∗(CO)2Fe]+
(Elsevier, 2012)
A series of water-soluble alkylaminopentamethylcyclopentadienyliron dicarbonyl complexes, [Cp ∗ (CO) 2 Fe{NH 2 (CH 2 ) n CH 3 }]BF 4 (n=2–6; Cp ∗ =η 5 -C 5 Me 5 ) and the diaminopropane bridged complex, [{Cp ∗ (CO) 2 Fe} ...
Syntheses and structural characterization of 2,4,6-trimethylaniline complexes of iron carbonyls
(Inorganica Chimica Acta, 2014)
The new 2,4,6-trimethylaniline complexes [Cp∗Fe(CO)2(NH2C6H2(CH3)3)]+ (3) and [CpFe(CO)2(NH2C6H2(CH3)3)]+ (4) (Cp∗ = η5-C5(CH3)5; Cp = η5-C5H5) have been synthesized and isolated in high yields as tetrafluoroborate salts. ...
