13C CP-MAS NMR of azacycle-thiourea inclusion compounds
(Taylor and Francis, 1998)
13C CP-MAS NMR spectra of thiourea host-guest inclusion compounds containing amines, 1-azabicyclo[2.2.2]octane, 1,4-diazabicyclo[2.2.2]octane, 3-azabicyclo[3.2.2]nonane and 1, 3, 5, 7 tetrazadamantane at 25°C are reported. ...
On the nature ofthe Ca binding to the hull of nixtamalized corn grains
Classification of commercial catuaba samples by NMR, HPLC and chemometrics
Syntheses and structural aspects of cyclodextrin/dialkylamine inclusion compounds
(Editura Stiintifica F. M. R., 1998)
We report the syntheses and structural aspects of cyclodextrin host-guest inclusion compounds containing linear secondary alkylamines (dipropyl, dibutyl, dipentyl, dihexyl, and dioctyl) at 25°C. Elemental analysis, C CP-MAS ...
Solid state NMR as a new approach for the structural characterization of rare-earth doped lead lanthanum zirconate titanate laser ceramics
(ELSEVIER SCIENCE BV, 2008)
To facilitate the design of laser host materials with optimized emission properties, detailed structural information at the atomic level is essential, regarding the local bonding environment of the active ions (distribution ...
Monitoring crystallization in lithium silicate glass-ceramics using 7Li→29Si cross-polarization NMR
(Elsevier BVAmsterdam, 2014-12)
Quantification of the crystalline versus amorphous fraction is an important objective for the structural characterization of glass-ceramics. Owing to its well-documented ability of differentiating between crystalline and ...
NMR study of styrene-butadiene rubber (SBR) and TiO2 nanocomposites
(Elsevier B.V., 2009-08-01)
The chemical behavior of styrene-butadiene rubber (SBR) and of the SBR/TiO2 and photodegraded SBR/TiO2 nanocomposites was investigated through nuclear magnetic resonance spectroscopy (NMR) in the solid state with magic ...
Magnetic resonance study of the crystallization behavior of InF3-based glasses doped with Cu2+, Mn2+ and Gd3+
The crystallization of fluoroindate glasses doped with Gd3+, Mn2+ and Cu2+ heat treated at different temperatures, ranging from the glass transition temperature (Tg) to the crystallization temperature (Tc), are investigated ...
