Chromatographic determination of 8-oxo-7,8-dihydro-2′-deoxyguanosine in cellular DNA: A validation study
Pierre Duez, M Helson, Touridomon Issa Some, Jacques Dubois and M Hanocq
Although a series of biomarkers are widely used for the estimation of oxidative damage to biomolecules, validations of the analytical methods have seldom been presented. Formal validation, that is the study of the analytical performances of a method, is however recognized as the best safeguard against the generation and publication of data wit(...)

Nucleation and growth in electrodeposition of metals on n-Si(111)
R. Krumm a, B. Guel b, C. Schmitz a, G. Staikov a,*
Initial stages of electrodeposition of Tl, Cd and Cu on n-Si(111) from sulfate electrolyte solutions are studied using cyclic voltammetry and chronoamperometry. Capacitance measurements in metal ion free solutions were used to determine the flat band potential of n-Si. Results show that the relative position of the metal equilibrium potential(...)

Electrodeposition of Pb on n-Si (111)
B. Rashkova, B. Guel, R.T. Pötzschke, G. Staïkov and W. J. Lorenz
Electrodeposition of lead was studied in the system n-Si(111)/Pb2+, ClO4
ÿ, H+ using cyclic voltammetry, chronoamperometry, ex situ optical microscopy and in situ scanning probe microscopy (SPM).
Comparative studies were also performed in the system HOPG(0001)/Pb2+, ClO4
ÿ, H+. No underpotential
deposition (UPD) of 2D Pb phases could be ob(...)

UV-VISIBLE AND IR SPECTRA OF IRON(II) PHTHALOCYANINE POLYMER COMPLEXES LINKED BY BIS-PYRIDINATO LIGANDS
KARIFA BAY0, GUY VENANCE OUEDRAOGO, GEORGES TERZIAN and DAVID BENLIAN
Abstract:The spectra of iron(II) phthalocyanine polymer complexes (FePcL)n with bispyridinato bridging ligands, where L = 44’-bipyridine (bpy), trans-1,2-(4-pyridyl)ethylene
(bpe), 1,2-bis-(4-pyridyl)ethane (bpa), are discussed in comparison with the spectra of FeIIPc
and FePcL'2, where L’ = pyridine, 4-cyanopyridine (4CNpy), in reference to(...)
