Linear Free Energy Relationships of the C-13 NMR chemical shifts in 5-(3-and 4-substituted arylazo)-4,6-dimethyl-3-cyano-2-pyridones
(Arkat Usa Inc, Gainesville, 2009)
The C-13 NMR chemical shifts of the C2 carbon atom in the heteroaromatic nuclei of seventeen 5-(3- and 4-substituted arylazo)-4,6-dimethyl-3-cyano-2-pyridones were determined in deuterated DMSO solution. For quantitative ...
The structure directing role of 1,3-diaminopropane in the hydrothermal synthesis of iron(III) phosphate
(Srpsko hemijsko društvo, Beograd, 2004)
13-Diaminopropane (DAP) was used as a structure-directing agent for the hydrothermal synthesis of an organically templated iron phosphate. During crystallization at 180 degreesC, iron phosphate (FePO-DAP) with a layered ...
Magnetic properties of hematite (α - Fe2O3) nanoparticles synthesized by sol-gel synthesis method: The influence of particle size and particle size distribution
(De Gruyter Open Ltd, 2019)
Using the sol-gel method we synthesized hematite (α - Fe2O3) nanoparticles in a silica matrix with 60 wt % of hematite. X-ray diffraction (XRD) patterns and Fourier transform infrared (FTIR) spectra of the sample demonstrate ...
