Detection of Adducts with Matrix Clusters in the Positive and Negative Ion Mode MALDI-TOF Mass Spectra of Phospholipids
(Zeitschrift fur Naturforschung. Section B: Journal of Chemical Sciences, 2009)
It is usually accepted that neutral phospholipids (PLs) generate singly positively charged ions, whereas negative PLs are easily detectable in the negative ion mode when analysed by matrix-assisted laser desorption and ...
{4-[(Carbamimidoylhydrazono)methyl-kappa N-2(1),N-4]-5-hydroxymethyl-2-methylpyridinium-3-olate-kappa O}(methanol-kappa O)copper(II) dinitrate
(Acta Crystallographica. Section C: Crystal Structure Communications, 2009)
The title compound, [Cu(C9H13N5O2)(CH4O)](NO3)(2), consists of square-planar cationic complex units where the Cu-II centre is coordinated by an N, N, O-tridentate pyridoxal aminoguanidine Schiff base adduct and a methanol ...
A Method for the Spectroscopic Diagnostic of the Peculiarities of Materials Using the Semi-Auger Effect
(Acta Physica Polonica A, 2009)
We investigated the low energy satellites in the Rontgen spectra using the many-particle theory. These satellites are results of the radiative semi-Auger decay of the inner vacancy states. We did not treat only ordinary ...
Thermal stability of acrylonitrile/chlorosulphonated polyethylene rubber blend
(Journal of Thermal Analysis and Calorimetry, 2009)
The properties of chlorosulphonated polyethylene (CSM) rubber, acrylonitrile rubber (NBR) and their blend (50/50 w/w) were studied. Fourier transform infrared (FTIR) studies supported that CSM/NBR rubber blend is self ...
Effect of Fe2+ (Fe3+) Doping on Structural Properties of CeO2 Nanocrystals
(Acta Physica Polonica A, 2009)
We have measured the Raman scattering and magnetization of pure and Fe2+(Fe3+) doped CeO2 nanopowders at room temperature. The Raman scattering spectra revealed the existence of CeO2 fluorite cubic structure for all ...
Oxidative Stress Is Reduced in Wistar Rats Exposed to Smoke from Tobacco and Treated with Specific Broad-Band Pulse Electromagnetic Fields
(Archives of Biological Sciences, 2009)
There have been a number of attempts to reduce the oxidative radical burden of tobacco. A recently patented technology, pulse electromagnetic technology, has been shown to induce differential action of treated tobacco ...
Transition metal complexes with pyrazole-based ligands. Part 29. Reactions of zinc(II) and mercury(II) thiocyanate with 4-acetyl-3-amino-5-methylpyrazole
(Journal of the Serbian Chemical Society, 2009)
The work is concerned with the crystal and molecular structures of zinc(II) and mercury(II) complexes with 4-acetyl-3-amino-5-methylpyrazole (aamp) of the coordination formulae [Zn(NCS)(2)(aaMP)(2)] and (HaaMP)(2)[Hg(SCN)(4)]. ...

Synthesis and characterization of ordered mesoporous silica
(Journal of Optoelectronics and Advanced Materials, 2009)
Ordered mesoporous silica SBA-15 materials were synthesized by using Pluronic P123 (non-ionic triblock copolymer, EO(20)PO(70)EO(20)) as a template, under acidic condition. These materials were characterized by nitrogen ...
Electrochemical synthesis of nanosized monetite powder and its electrophoretic deposition on titanium
(Colloids and Surfaces. A: Physicochemical and Engineering Aspects, 2009)
Electrochemical synthesis of nanosized monetite powder was performed galvanostatically from homogeneous Solution of Na(2)H(2)EDTA center dot 2H(2)O, NaH2PO4 and CaCl2 at a concentration relationship Ca/EDTA/PO43- of ...
