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 ...
NMR Characterization and Rietveld Refinement of the Structure of Rehydrated AlPO4-34
(American Chemical Society, 2000)
The triclinic form of AlPO4-34, a microporous aluminophosphate with the chabazite (CHA) topology, adopts a rhombohedral symmetry upon calcination. The framework structure of this phase remains intact under ambient conditions, ...
Gain optimization in electrically pumped AlGaAs quantum cascade lasers
(Optical Soc Amer, Washington, 2002)
The design of the active region of a current-pumped quantum-cascade laser to achieve maximal gain is proposed. Starting with an arbitrary smooth potential, a family of isospectral Hamiltonians with a predefined energy ...
Second harmonic generation at the quantum-interference induced transparency in semiconductor quantum wells: The influence of permanent dipole moments
(IEEE-Inst Electrical Electronics Engineers Inc, Piscataway, 2001)
The influence of permanent dipole moments of quantized states on intersubband second harmonic generation based on quantum-interference induced transparency in semiconductor quantum wells is explored using the harmonic ...
Mathematical modeling of gel drying with supercritical carbon dioxide / Matematičko modelovanje sušenja gela natkritičnim ugljen dioksidom
(Association of the Chemical Engineers of Serbia, 2001)
The most complex step in the production of aerogels is the supercritical drying step, and it is therefore important to study its dynamics using mathematical models. Alumina/silica aerogel was obtained using a one step ...

Diversity of the human gastrointestinal microbiota
(Teknoscienze Publ, Milano, 2007)
Our gastro-intestinal tract is populated by reportedly the densest microbial ecosystem that is essential for the digestion of foods and affects health. The basic understanding of the human microbiota is rapidly expanding ...
A tissue-implant reaction associated with subcutan implantation of alpha-tricalcium phosphate, dental ceramic and hydroxyapatite bioceramics in rats / Tkivo-implant reakcija povezana sa subkutanom implantacijom alfa-trikalcijum fosfata, dentalne keramike i hidroksiapatit biokeramike kod pacova
(Univerzitet u Beogradu - Fakultet veterinarske medicine, Beograd, 2008)
Calcium phosphate ceramics are among the more commonly used and biocompatible ceramics. Recently, we have synthesized a new calcium phosphate ceramic, alpha tricalcium phosphate (aTCP). The aim of this study was to assess ...
HPLC behavior and hydrophobic parameters of some anilides
(Springer Heidelberg, Heidelberg, 2001)
The chromatographic behavior of para substituted anilides of 2,2-dimethylpropanoic, benzoic and alpha -phenyl acetic acid has been studied by reversed-phase high performance liquid chromatography HPLC was performed on a ...
