Summary:
Several types of electrodeposited ruthenium electrodes on
a platinum substrate have been studied. The first type was
prepared by a galvanostatic deposition using 40 mA cm-2
current density and varying deposition time from 1 to 60
min. The electrode has been electrochemically activated to
a second type by square wave pulses between -0.2 and 0.85
V vs. SCE. The complete reduction of the oxide is a
necessary condition for the activation process.

Summary: Results of impedance analysis of Fe80B20 glassy alloy in
sulphuric acid in three distinct anodic potential ranges are
presented. Dominant electrode processes are found to be: (i)
kinetically controlled charge transfer mediated by
adsorption of some intermediate species in the active
dissolution range, (ii) the same process, but with a
blocking effect due to adsorption of the passivating species
in the passivation range, and (iii) ion migration within a
passive layer in the passive region.

Summary: The anodic behaviuor of galvanically plated
ruthenium-iridiumcoating on titanium was investigated. The presence
of 40% of iridium in the coating yielded 300 times higher
stability in comparison with the coating of pure ruthenium.
In addition, a square-wave pulsing between -0.25 and 1.25 V
vs the saturated calomel electrode produced an oxide film
with electrochromic properties which were directly related
to the charge enhancement factor of the grown oxide.

Summary: Hydrous oxide growth on rhodium electrodeposited on
titanium was investigated with respect to electrocatalytic
activity and stability of the coating in the oxygen
evolution reaction from 1 mol dm-3 NaOH solution. An
enhancement of the charge storage capacity by a factor of
four was achieved by square-wave pulsing between -1.05 and
0.45 V vs. SCE. The grown oxide exhibited a rate of oxygen
evolution enhanced by about one order of magnitude
accompanied by a decrease of the Tafel slope.

Summary: The electrocatalytic activity and anodic stability of
electrodeposited ruthenium, iridium and rhodium coatings on
titanium in oxygen evolution reaction from 0.5 mol dm-3
sulphuric acid have been investigated. Ruthenium exhibited
the highest electrocatalytic activity evidenced by the
lowest Tafel slope of 30 mV/decade and the highest current
density. The anodic galvanostatic polarization proved
rhodium to be the most stable coating.

Summary: Landau and Lifehitz have deduced a fugacity of 1017 bar
that
would lead to states in which the capturing of electrons by
nuclei whith emission of neutrinos is thermodinamically
favored. Pressure and corresponding fugacities are
calculated and compared to the above quoted value. The
relation of fugacity to the mechanism of deuterium evolution
on the surface of the metal, pressure and cracking when
pressure in voids exceeds the spreading pressure of the
metal is discussed.

Summary: A Pd electrode has been examined which produced a
concentration of tritium in 0.1 M LiOD solution around 103
times above background. Tritium production at a given
potential ceased after a few days, but could be restored by
a small increase of the deuterium overpotential.
Correspondingly, He+ was found in 9-10 pieces of the Pd
electrode at 2-100 times background. The surface of the
electrode contained a Cu-mosaic structure, not seen on the
inactive electrode.

Summary: X-ray photoelectron spectroscopy and Auger electron
spectroscopy were used for the characterization of an
electrodeposited ruthenium electrode (unactivated) and an
electrode subjected to electrochemical activation. It was
found that both electrodes consist of a mixture of ruthenium
oxides, hydroxides and adsorbed water molecules. The most
prominent difference between the samples is a significantly
higher hydroxyl content in the case of the activated
electrode.

Summary: Anodic films formed by passivation of Fe80B20 were studied
using impedance spectroscopy. An insulator or n-type
semiconductor barrier layer impedance determines the total
impedance if the films are formed in the borate-buffer.
Those films exhibit a perfect protective behaviour against
corrosion. In the acid sulphate solution, lower protective
passive films are formed, with the total impedance
determined by a bilayer structured passive film.

Summary: The complex oxide of composition Pb1+xZr0.52Ti0.48O3
(x=0.025 or -0.01) was produced by the solid state reaction
of the composite oxide PbO, ZrO2 and TiO2 at 900oC. The
synthesized sample was at least two phase tetragonal. Free
PbO was found in the lead-zirconate-titanate (PZT) sample
when an excess of lead oxide was added to the reaction
mixture. Zirconium and titanium oxides exhibited isoelectric
points in sodium chloride and ammonium acetate at pH 7.0 for
ZrO2 and pH 3.5 for TiO2.

Summary: Tritium production was measured in the liquid and gas
phases
on Pd codeposited with deuterium from PdCl2 + LiCl + D2O
solutions. During two weeks of electrolysis in four out of
six cells, average excess tritium levels pf 1.9 times in the
gas phase and 1.6 times in the liquid phase were found over
those expected from the separation factor. The largest
excess of tritium found was three times that calculated
theorethically from the separation factor.

Summary: The hydrous oxide film, with a charge enhancement factor of
19, exhibited two stages of oxide reduction. Coulometric data showed that
the majority of the oxide (80-90%) was reduced in Ni(III)/Ni(II) transition
almost reversibly while, depending on the potential of formation, about
10-20% of the NiOOH was irreversibly reduced. The hydrous oxide layer was
stable over 14 days of electrolysis with an unchanged charge enhancement
factor.

Summary: The heterogeneous electron transfer in (Fe(CN)6)4-/3/ and
aquo complexes of Fe3+/2+ redox couples have been investigated on a
ruthenized platinum electrode. Voltammetric data measured on a rotating
disc electrode showed that a ruthenized platinum layer was a good
electronic conductor. The heterogeneous electron transfer rate constant of
3.9x10-5 cm s-1 on the unactivated electrode increased by 30% in the case
of the activated electrode.

Summary: The increase of charge storage capacity of the grown oxide
for a factor of two was obtained. An about one order of magnitude enhanced
rate of oxygen evolution accompanied by a decrease of the Tafel slope from
50 to 40 mV/decade was measured on the grown oxide. The X-ray
photoelectron spectroscopy oxygen spectra have shown that the enhanced rate
of oxygen evolution was in direct correlation with the increase of hydroxyl
groups in the coating.

Summary: The anodic stability of an electrodeposited ruthenium
electrode was measured by anodic galvanostatic polarization. The role of
water in electrode stability was determined of thermogravimetric analysis.
The loss of hydrous component of the oxide layer was in direct correlation
with the increase of the anodic stability. This finding was confirmed by
X-ray photoelectron spectroscopy measurements.

Summary: Pb(Zr,Ti)O3 solid solutions were synthesized by solid state
reaction of the constituent oxides. Microelectrophoresis was
applied to analyze the isoelectric conditions of the
individual oxide components and of the synthesized complex
oxides. According to the similarity between the isoelectric
points of ZrO2 and PZT, it seems that zirconium oxide has
major influence on the electrokinetic charge and potential
of the synthesized complex oxide(PZT).

Summary: The charge enhancement factor (CEF) i.e. the increase of
the
voltammetric charge before and after the activation of the
electrodeposited electrode is considerably smaller than CEF
for the bare electrode. However, a relatively large specific
surface area of the electrodeposited rhodium and the
enhancement of the OER for about one order of magnitude
recommends the use of this electrode in electrocatalysis.

Summary: The coatings exhibited different specific surface areas due
to different current efficiencies in electrodeposition.They
were determined measuring the charge for the hydrogen
monolayer deposition.The roughness factor was 30 and 800 in
the case of Ir and Rh electrode respectively.It was
determined that Ir exhibited the highest electrocatalytic
efficiency in the OER probably due to the most compact oxide
layer.

Summary: The essential request in PZT synthesis are the purity of
raw
materials (PbO, ZrO2 and TiO2) and their surface reactivity.
In aqueous electrolyte solutions (chloride, acetate,
nitrate), due to relative solubility of lead(II) oxide
(litharge) of 1.7 mg/L, various hydrolized and other complex
species of Pb are present.By adsorption, they modify the
surface charge, and consequently, the electrokinetic
potential, depending on the concentration of the suspension,
concentration of the electrolyte solution, and its pH.
