Impact of carboxymethylcellulose on morphology and antibiotic production by Streptomyces hygroscopicus
(Current Microbiology, 2008)
A chemically defined media consisting of carboxymethylcellulose (CMC) was developed to maximize the production of antibiotics, hexaene H-85 and azalomycine, by Streptomyces hygroscopicus CH-7. The production of antibiotics ...
Kinetics of the Formation of Poly(methyldecylsiloxane) by Hydrosilylation of Poly(methylhydrosiloxane) and 1-Decene
(Switzerland : Trans Tech Publications LTD, 2007)
Poly(methylhydrosiloxane) [PMHS], prepared by siloxane equilibration reaction, was used for the hydrosilylation with 1-decene to obtain poly(methyldecylsiloxane) [PMDS]. Pt(0)-1,3-divinyltetramethyldisiloxane complex was ...
Characterization of copper powder particles obtained by electrodeposition as function of different current densities
(Journal of Applied Electrochemistry, 2009)
Technological properties of powders depend on their granulometry and morphology. Very often one method is inadequate for characterization of powder particles. This article studied different methods intended for clear ...
Nanostructural Analysis of Mirror – Bright Zinc Coatings
(MAIK "Nauka /Interperiodica" (Russia), 2006)
The zinc coatings electrode posited from solution containing dextrin/salicyl aldehyde mixture are
examined by the scanning tunneling microscopy (STM). It is shown that mirror brightness of these zinc deposits is associated ...
Reflection and structural analyses of mirror-bright metal coatings
(Springer, 2004)
Reflection and structural analyses of different copper and zinc coatings were performed. The copper coatings were electrodeposited from a sulfate solution in the presence of thiourea, as well as in the presence of modified ...
Dithiophenes and other constituents of roots of Centaurea nicolai
(Oxford : Pergamon-Elsevier Science Ltd, 2003)
Centaurea nicolai Bald. is an endemic species found in the Mediterranean part of Montenegro, and in Albania. Roots of C. nicolai were collected on the south slopes of mountain Rumija on the Adriatic coast of Montenegro.
Synthesis of mesoporous nanocrystalline titania powders by nonhydrolitic sol-gel method
(Academic Press Ltd- Elsevier Science Ltd, London, 2009)
Mesoporous titania with well-crystallized anatase phase was synthesized by nonhydrolytic sol-gel process combined with solvothermal treatment. Titanium-isopropoxide, titanium-tetrachloride, and carbon-tetrachloride were ...
Electrochemically deposited Ni+WC composite coatings obtained under constant and pulsating current regimes
(Netherlands : Kluwer Academic Publishers, 2004)
A series of Ni þ WC composite coatings were obtained by electrodeposition on a rotating disc electrode (RDE)
from a commercially available Watts bath containing additives for brightness and smoothing and insoluble ...
On the relationship between effective electron mobility and kink effect for short-channel PD SOINMOS devices
(World Scientific Publ Co Pte Ltd, Singapore, 2008)
Here, a new approach for calculating the triggering drain bias at the onset of the kink effect, kink voltage, V-kink, for PD SOI NMOS devices utilizing electron drift properties in the channel is given. This approach ...
Characterization of recombinant antibodies for detection of TNT and its derivatives
(Versita, 2009)
Diverse recombinant immunoreagents specific for TNT–derivatives were tested in different assay forms in order to analyze their specificity and sensitivity. Performance of immunoassays was based on TNP–protein conjugates ...
