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 ...
Particle-to-particle heterogeneous nature of Coals A case of large coal particles
(Taylor & Francis Inc, Philadelphia, 2009)
In the present paper, the results of investigation of the heterogeneous nature of coals are given. Microscopic observations of coals of different rank and mineral matter content were performed. The content of minerals and ...
Macroporous poly(glycidyl methacrylate-co-ethylene glycol dimethacrylate) resins-Versatile immobilization supports for biocatalysts
(Elsevier, 2009)
Crosslinked macroporous hydrophilic poly(glycidyl methacrylate-co-ethylene glycol dimethacrylate)s [abbreviated poly(GMA-co-EGDMA)] with identical chemical structure (60% of glycidyl methacrylate) but with varied average ...
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 ...
Electrochemical Oxidation of Phenol on Metal-Impregnated Zeolite Electrodes
(Wiley-V C H Verlag Gmbh, Weinheim, 2009)
Nanodispersed metallic clusters of platinum, silver and cobalt were incorporated into NaX zeolite cavities by impregnation with acetone solution of corresponding acetylacetonates and solvent evaporation followed by ...
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 ...
Preparation of silver(I) complexes with itaconic acid-based hydrogels for biomedical application
(Materials and Manufacturing Processes, 2009)
Silver(I) complexes based on itaconic acid hydrogel were prepared and characterized in order to examine the potential use of these materials. FTIR, AFM, in vitro fluid-uptake, metal sorption, and antibacterial activity ...
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 ...
Performance limits to the operation of nanoplasmonic chemical sensors: noise-equivalent refractive index and detectivity
(Spie-Soc Photo-Optical Instrumentation Engineers, Bellingham, 2009)
We considered figures of merit for chemical and biological sensors based on plasmonic structures and utilizing adsorption/desorption mechanism. The operation of these devices in general is limited by noise determining the ...
