Polarographic determination of hydrogen peroxide in perborate containing commercial detergents under the bleaching process condition
(Electroanalysis, 1997)
Differential pulse (DP) and current sampled (TAST) polarography were applied for measuring hydrogen peroxide in actual washing systems. In addition to the possibility of the hydrogen peroxide determination in commercial ...
Universal scaling of critical quasiperiodic orbits in a class of twist maps
(Journal of Physics A-Mathematical and General, 1998)
Recently we have shown that the fractal properties of the critical invariant circles of the standard map, as summarized by the f(alpha) spectrum and the generalized dimensions D(q), depend only on the tails in the continued ...
Discontinuities in the temperature function of transmembrane water transport in Chara: Relation to ion transport
(Journal of Membrane Biology, 1999)
The NMR (nuclear magnetic resonance) method of Conlon and Outhred (1972) was used to measure diffusional water permeability of the nodal cells of the green alga Chara gymnophylla, Two local minima at 15 and 30 degrees C ...
Polarographic and electrochemical studies of some aromatic and heterocyclic nitro compounds, part III: Electroreduction of mono‐ and dinitropyrazoles and ‐imidazoles
(Electroanalysis, 1992)
The reduction of mono‐ and dinitropyrazoles and of nitroimidazoles follows the general pattern of reduction of aromatic nitro compounds: The nitro group is reduced in a four‐electron step to a hydroxylamino group and the ...
Polarographic and electrochemical studies of some aromatic and heterocyclic nitro compounds, part IV: Polarographic reduction of 2‐alkylnitroimidazoles and aminonitroimidazoles
(Electroanalysis, 1992)
1, 2‐Dialkyl‐4‐nitroimidazoles are reduced between pH 0 and 13 in a four‐electron wave. The resulting arylhydroxylamine is stable and in acidic media reduced further to the amine. 1,2‐Dialkyl‐5‐nitroimidazoles and ...
Polarographic study of Eriochome cyanine R and its aluminium complexes
(Srpsko hemijsko društvo, Beograd, 1997)
The behaviour of the two main cathodic polarographic waves of the dye Eriochhrome cyanine R (ECR), A at - 0.45V, and B at -1.0 vs. SCE, were followed from acetate buffer pH 4.8 in the presence of Al3+ ions. Two new waves ...
Reactions of Hydrous Titanium Oxide Colloids with Strong Oxidizing Agents
(Langmuir, 1992)
The absorption spectra of the transients formed in the reactions of titanium hydrous oxide with SO4•-, Tl2+, or OH* species in alkaline aqueous solution have been studied by using the pulse radiolysis technique. Direct ...
Characterization of metal iodide quantum dots
(Advanced Materials for High Technology Applications, 1996)
Different synthetic procedures for preparation of the nanometer scale metal iodide particles in liquid solutions and their incorporation in silicate glasses have been developed. Optical properties of small metal iodide ...
Charge-transfer reactions between C-60 and hydrophilic solutes
(Advanced Materials and Processes: YUCOMAT II, 1998)
Two different procedures for dissolving fullerene molecule C-60 into aqueous solutions have been developed. Embedding C-60 clusters into a water-soluble host molecule of gamma-cyclodextrin resulted in relatively low ...
Nanocomposite materials prepared by using quantum dots as building blocks
(Advanced Materials and Processes: YUCOMAT II, 1998)
Two different synthetic procedures for preparation of composite materials using semiconductor quantum dots as building blocks have been developed. The resulting powders preserved optical and photocatalytic properties of ...
