Spectroscopic and quantum chemical investigations of substituent effects on the azo-hydrazone tautomerism and acid-base properties of arylazo pyridone dyes
(Oxford : Pergamon-Elsevier Science Ltd, 2014)
A series of 5-(4-substituted arylazo)-6-hydroxy-4-methyl-3-cyano-2-pyridone dyes was synthesized and the structure of the dyes was confirmed by UV-Vis, FT-IR, H-1 NMR and C-13 NMR spectroscopic techniques. The azo-hydrazone ...
CO2 Conversion Enhancement in a Periodically Operated Sabatier Reactor: Nonlinear Frequency Response Analysis and Simulation-based Study
(Wiley, 2018)
Conversion of CO2 into synthetic CH4 via thermocatalytic hydrogenation (the Sabatier reaction), has recently gained increasing interest as a possible route for CO2 utilization and energy storage pathway. Herein, we analyze ...
Lipophilicity of some guaianolides isolated from two endemic subspecies of Amphoricarpos neumayeri (Asteraceae) from Montenegro
(Biomedical Chromatography, 2009)
In this study 10 guaianolide-type sesquiterpene γ-lactones named amphoricarpolides, isolated from the aerial parts of two endemic subspecies of Amphoricarpos neumayeri (ssp. neumayeri and ssp. murbeckii Bosnjak), were ...
Periodic Operation with Modulation of Inlet Concentration and Flow Rate Part II: Adiabatic Continuous Stirred-Tank Reactor
(Wiley-V C H Verlag Gmbh, Weinheim, 2016)
The nonlinear frequency response (NFR) method, which is an analytical, fast, and easy method for evaluating the performance of forced periodically operated chemical reactors, was used to investigate possible improvements ...
Study of Nd-Fe-B alloys with nonstoichiometric Nd content in optimal magnetic state
(International Institute for the Science of Sintering, Beograd, 2009)
Characterization of two rapid-quenched Nd-Fe-B alloys with nonstoichiometric Nd content in the optimized magnetic state was carried out using the X-ray diffractometry (XRD), 57Fe Mössbauer spectroscopic phase analysis (MS), ...
Synthesis and biological evaluation of some 17-picolyl and 17-picolinylidene androst-5-ene derivatives
(Elsevier, 2007)
Starting from dehydroepiandrosterone (1) 17-picolyl (2), 17-picolinylidene (7), 17-picolinylidene-16-one (10 and 11), and 17-picolyl-16-one (15) derivatives of androst-5-ene were synthesized in one, two, four and five steps ...
Effect of cooling rate on the microstructure and magnetic properties of melt spun Nd-Fe-B alloys
(Elsevier, 2003)
The results of X-ray analysis, Mossbauer spectroscopy and magnetic measurement for melt-spun Nd-Fe-B with low content Nd obtained by optimal selected cooling rate and heat treatment are presented to bring some new information ...
Characterization and Morphology of Copper Powder Particles as a Function of Different Electrolytic Regimes
(Esg, Belgrade, 2010)
The effect different deposition regimes (constant and reversing currents), on the powdered copper electrodeposits morphology were investigated. The results obtained in constant regimes were compared with those obtained in ...
Characterization of a low cost Lagenaria vulgaris based carbon for ranitidine removal from aqueous solutions
(Elsevier, 2017)
Practical aspects of Lagenaria vulgaris shell conversion to activated carbon were examined along with its use in ranitidine adsorption. Kinetics and isotherms of adsorption onto Lagenaria vulgaris carbon (LVC) were correlated ...
Decolorization of textile dyes and effluents using potato (Solanum tuberosum) phenoloxidase
(Elsevier Sci Ltd, Oxford, 2012)
Potatoes are desirable source for polyphenol oxidase (PPO, EC 1.14.18.1) purification because this enzyme can be purified from the food industry waste such are potato peels from potato chips industry. This paper presents ...
