Fingerprints of Both Watson–Crick and Hoogsteen Isomers of the Isolated (Cytosine-Guanine)H + Pair
(American Chemical Society, 2017-11-24)
Gas phase protonated guanine-cytosine (CGH+) pair was generated using an electrospray ionization source from solutions at two different pH (5.8 and 3.2). Consistent evidence from MS/MS fragmentation patterns and differential ...
Theory of small-signal ac response of a dielectric liquid containing two groups of ions
(AMER INST PHYSICS, 2008)
The analysis of Macdonald for electrolytes is generalized to the case in which two groups of ions are present. We assume that the electrolyte can be considered as a dispersion of ions in a dielectric liquid, and that the ...
Cation size effects in mixed-ion metaphosphate glasses: structural characterization by multinuclear solid state NMR spectroscopy
(Royal Society of Chemistry - RSCCambridge, 2013-09)
Metaphosphate glasses with two monovalent species A1-xBxPO3 (0 <= x <= 1) show mixed-ion effects (MIE) in the dc conductivities and glass transition temperatures, which are strongly dependent on the cation size mismatch ...
Chemical profile of meta-chlorophenylpiperazine (m-CPP) in ecstasy tablets by easy ambient sonic-spray ionization, X-ray fluorescence, ion mobility mass spectrometry and NMR

Characterization of humic-rich hydrocolloids and their metal species by means of competing ligand and metal exchange - an on-site approach
(Royal Soc Chemistry, 2002-10-01)
An improved on-site characterization of humic-rich hydrocolloids and their metal species in aquatic environments was the goal of the present approach. Both ligand exchange with extreme chelators ( diethylenetetraaminepentaacetic ...

Structural characterization of the lithium silicides Li15Si4, Li13Si4, and Li7Si3 using solid state NMR
(Royal Society of Chemistry - RSCCambridge, 2012)
Local environments and lithium ion dynamics in the binary lithium silicides Li15Si4, Li13Si4, and Li7Si3 have been characterized by detailed variable temperature static and magic-angle spinning (MAS) NMR spectroscopic ...
Fingerprint of semi-crystalline structure memory in the thermal and ionic conduction properties of amorphous ureasil-polyether hybrid solid electrolytes
(2022-02-04)
Correlations among the structure, thermal properties, and ionic conductivity of solid polymer electrolytes (SPEs) were studied using a ureasil-polyethylene oxide (U-PEO) organic-inorganic hybrid prepared according to a ...
Structural and dynamic characterization of Li12Si7 and Li12Ge7 using solid state NMR
(Academic PressLondon, 2012-04)
Local environments and lithium ion dynamics in the binary lithium silicide Li12Si7, and the analogous germanium compound have been characterized by detailed 6Li, 7Li, and 29Si variable temperature static and magic-angle ...
