Study of forced degradation behavior of Eletriptan hydrobromide by LC and LC-MS and development of stability-indicating method
(Elsevier, 2009)
The objective of the present study was to report the stability profile of novel antimigrain drug Eletriptan hydrobromide based on the information obtained from forced degradation studies. The drug was subjected to acid ...
Planar chromatography of cholic acid-derived cis-trans isomeric bis-steroidal tetraoxanes
(Journal of Planar Chromatography - Modern TLC, 2009)
Seven pairs of cis-trans isomers of bis-steroidal tetraoxanes have been examined by both normal-phase (NP) and reversed-phase (RP) planar chromatography. Unmodified silica gel was used with ethyl acetate-toluene and ethyl ...
Analytical modelling of thermopile based flow sensor and verification with experimental results
(Elsevier, 2009)
A novel, simple approach for analytical modelling of thermal flow sensors has been implemented. It is based on unification of results obtained using the already developed two-zone analytical model and theory of laminar ...
SO2 Retention by CaO-based sorbent spent in CO2 looping cycles
(American Chemical Society (ACS), 2009)
CaO-based looping cycles are promising processes for CO2 capture from both syngas and flue gas. The technology is based on cyclical carbonation of CaO and regeneration of CaCO3 in a dual fluidized-bed reactor to produce a ...
Synthesis of the first thiazolidine-condensed five-, six-, and seven-membered heterocycles via cyclization of vinylogous N-acyliminium ions
(Synlett, 2009)
Synthesis of new thiazolidine-fused five-, six-, and seven-membered heterocycles through vinylogous N-acyliminium ion-cyclization sequence, involving positions 3 and 4 of the thiazolidine ring, is described. The formation ...
Reactively sputtered Ni, Ni(N) and Ni3N films: Structural, electrical and magnetic properties
(Elsevier, 2009)
Nickel thin films were deposited on glass substrates at different N2 gas contents using a dc triode sputtering deposition system. Triode configuration was used to deposit nanostructured thin films with preferred orientation ...
Oxidation of formic acid on platinum surfaces decorated with cobalt(III) macrocyclic complexes
(Maik Nauka/Interperiodica/Springer, New York, 2009)
Platinum electrode decorated with three different mixed-ligand cobalt(III) complexes of the general formula [Co(Rdtc)cyclam](ClO4)(2) [cyclam = 1,4,8,11-tetraazacyclotetradecane, Rdtc(-) = morpholine-(Morphdtc), ...
Synthesis, characterization and biological activity evaluation of Pt(II), Pd(II), Co(III) and Ni(II) complexes with N-heteroaromatic selenosemicarbazones
(Elsevier Science Sa, Lausanne, 2009)
Five new complexes of Pt(II), Pd(II), Co(III) and Ni(II) with 2-pyridine(quinoline)carboxaldehyde selenosemicarbazones were synthesized and characterized. Crystal structures of Pt(II) complex with the pyridine derivative ...
Two-layer adsorption and adsorbed mass fluctuations on micro/nanostructures
(Elsevier, 2009)
This paper presents for the first time the analysis of fluctuations of both the number of adsorbed particles and the adsorbed mass in the case of multilayer adsorption on the surface of MEMS/NEMS structures, described by ...
Fishnet-Based Metamaterials: Spectral Tuning Through Adsorption Mechanism
(Polish Academy of Sciences, 2009)
In this work we consider the tuning of spectral reflectance of fishnet metamaterials with circular or elliptic apertures due to the presence of dielectric analyte adsorbed within the pores of the dielectric part. We simulated ...
