The receptors at the level of the cervix and corpus uteri, and of the fallopian lube,
were studied by means of a special method of stimulation. Simultaneous plethysmo-
graphic recordings of the vaso-motor variations were made. The stimuli used
were either mechanical (tractions) or intrauterine, and intratubal pressure varia-
tions caused by the slow or sudden Introduction of carbon dioxide Into the uterine
cavity. The plethysmogram showed deviations in all cases of mechanical stimula-
tion of the cervix and in most of the cases of uterine baro-receptor stimulation
through pressure variations. The presence of changes in the plethysmogram during
the passage of carbon dioxide through the fallopian tubes suggests the existence of
baro-receptors at this level. (U, 10*)

Title : On the Storage and the Leaching of Smoke Tree (Variability
of Sume Tanning Agents) -
Orig Pub : Bor-es cipotechnika, 1957, 7, No 1, 1-3
Abstract ; The tanning (T) content in the wood of the smoke tree
bush Rhus cotinus irvestigated (50-year old) was higher
than in -the young sprouts or in the bark. Wood dyes
powdered hide into yellow (while dyes it bark T into
grey-brown), no precipitate with CH20 (while bark T gives
an abundant precipitate), produces a blue coloration in
presence of FeCl3 (while bark T give a green color).
Sum,c T is less stable than T from the Chinece nut tree.

were investigated. It was found that a decrease in chromi-? acni
concentration increases the rate of chromium deposition sharp.y,
the rate of increase depending on H 2so4 concentration, tempera-~ure
and current density. The rate of in'~ermediate reduction ~,f -tiromic
acid also increases and the rate of hydrogen evolution decreases.
A decrease of chr9mic acid concentration with simulTaneoua j-:~crea-
se in sulphuric acid concentration increases the rate of elirox--,um
deposition considerably. However, the rate of intermediate r,educ-
tion of chromic ac3.d is initially independent of the CrO., and HI)
so4 concentration and subsequently decreases with a deer,~!s- in"
CrO3 and H2so4 concentration. The authors suggest that on ,haaging
the solution compositiong the change in the rates of the linked
reactionsp taking place at the cathode during reduction cf -nromic
acid in the presence of H 2SU 4' is due to a change in ::ornipoilt~!-Dn
and properties of the cathode film formed, from which dischar,~e of

TITLEs Effect of film composition on alloy formation during electro-
deposition of chromium together with other elements
PERIODICALt Zhurnal fizicheskoy khimii, v. 35, no. 3, 1961, 647-650
TEM The effect of film composition on the electrodeposition of chromium
together with other elements was studied. It was established that the de -
position of metallic chromium depends on the composition of the film andnot
on the composition of the electrolyte solution. Investigation of the catkx,.lic
polarization in an electrolyte consisting of 2.5 moles/I of CrO. and 0.025
mole/1 of selenic acid on a gold cathode showed that, in principle, the ef-
fect of selenic acid on the electroreduction of chromic acia is the same as
that of sulfuric acid. An alloy of chromium with selenium forms on the
cathode during this process. This alloy also forms when adding Belenious
acid instead of selenic acid. The reduction rate of the chromium ions is af-
fected,not by the ion concentration in the electrolyte, but by the ion con-
centration in the film. The change of the composition of the Cr-Se alloy

on a change of the concentration of selenic acid in a 2.5 I'l chromic-acid
solution at a current denuity of 0-50 a/cm2 and a temperature of 20 0C was
also investigated on platinum electrodes. The results showed that tile
p rcentage of selenium in the alloy rises to 0.15 mole/l with an increase of
R. e selenium concentration in the solution. The composition of the Or-Se
alloy"remains unchanged with a further increase of the selenium noncentratian.
The same rule was also established for a replacement of selenic acid by
selenious acid. During electroreduction the permanganate ion has no reduc.-
ing effect on chromic acid. The ability of forming a film an the cathode
thus depends first of Pill on the nature of the anions. The effect of tile
sulfuric-acid concentration on the percentage of selenium in the Cr-Se alloy
during deposition from a solution with 2.5 moles/l of chromic acid and
0.1 mole/I of selenic acid was studied, and it was established that the
selenium content in the electrolytic deposit decreases with increasing
sulfuric-acid concentration. Partial exchange of sulfuric acid for selenic
acid in the film results in a decrease of the reduction rate of the selenium
ions. There are 3 figures and 5 references: 4 Soviet-bloc and 1 non-

TITLEt Polarization during electrodeposition of iron group metals.
1. Steady-state potential and overvoltage of iron deposition
PERIODICAL: Zhurnal fizicheskoy khimii, v. 35, no. 7, 1961, 1406 - 1410
TEXT: The authors studied deposition and dissolution of iron in 1 N FeSO 4
solution at 250C. The electrodeposited iron was found to dissolve in these
solutions in the absence of polarizing current, particularly in a more acid
solution. In this case (pH 1-5-2-5) the rate i c of t he spontaneous dissolu-
tion rapidly decreases with increasing pH(i. . 0-4ma/cm at pH 1-5). On
further change of the pH from 2.5 to 3.5 the rate of spontaneous dissolution
2
is reduced more slowly (i. - 0.065ma/cm at pH - 3). The following reac-
tions take place at the electrode surfacet H+ + e-o, 1 H -1 H _>H+ + 0,
2+ 2+ i 21 2 2
Fe + 2e 4Fe, Fe-#Fe + 2e. The reaction rates are denoted by Fit F 29F 31

F4' The equation for the steady state is then: F 1+ F 3 - F2 + F4' The
potential of the Fe electrode being more negative than that of hydrogen,
the ionization rate F2 of H 2 may be neglected. Assuming that the discharge
rai, F3 of the Fe ions be much less than that of the H +, F,,one may write
F1 - F49+ i.e., the charge of the electrode is compensated by the discharge
of the H ions. The change of dissolution in-.the presence of 1N Al 2(S04)3
was also studied. At pH 1-5-3-5 the rate of dissolution increases in
this case. (pH - 1.5, 'c 0.52 ma/cm2, PH - 3, ic - 0.31 ma/cm 2). This is
due to SO __ absorption on the electrode which accelerates the ionization of
4
the metal atoms. In the presence of aluminum sulfate the polarization of
the anode is decreased by 35mv. With rising temperature of the electrolyte
the rate of spontaneous dissolution increases, particularly in the presence
of aluminum sulfate. At a temperature rise from 25 to 600C at PH - 1.5 the.
rate increases to the 7.5-fold, in the presence of aluminum sulfate to th5y,
22-fold. At low PH the steady-state potential changes quickly with a
Card 2/3

change in pH, at a higher pH this change is less significant. At low pH
the dependence may be expressed by the following formulat
Irs t - A + RT ln [H+]
( 06 + 13) F
At higher pH the potential is shifted more to the negative aide. In an
oxygen-free inert atmosphere the deviation of the steady-state potential
from the rule, expressed by the formula, decreases. At higher pH the
steady-state potential is shifted toward the positive side under the influ-
ence of aluminum sulfate. The potential of the Fe electrodo is irrevorui-
ble in sulfuric aoid solution and is datormined by a number of processes.
It is therefore impossible to determine the overvoltage by the steady-state
potential. The deposition potential was determined relative to a saturated
calomel electrode. With increasing pH the deposition potential of Fe is
shifted toward the negative side. At a given current density and inareasing
pH the overvoltage of the deposition has more positive values, except in
very acid solutions. The determination of overvoltage by the steady-state
potential thus seems to be incorrect and gives contradictory results.
There are 5 figures and 6 Soviet references.

TITLEt Polarization during electrodeposition of iron group metals
II. Electrodeposition of iron
PERIODICALt Zhurnal fizicheskoy khimii, v. 35, no. 7, 1961, 1411 - 1415
TEXTt The authors investigated the electrolytic deposition of iron from
solutions of 1 N FeSO 41 and I N FeSO4 + I N Al 2(so 4)3at a current density
2
of 20 ma/cM . The yield of metal relative to the current changes only lit-
tle with a change in current density, and increases rapidly with increasing
pH in the range 1.5-2.5. By changing the pH by one unit the yield increases
from 20 to 90c/6. At a further pH increase the yield increases but slightly.
On aluminum sulfate addition the yield is only 4% at the optimum pH. All
curves showing the dependence of the potential of the iron electrode on the
pH pass a maximum at pH 2.0-2.2. The maximum of the polarization curves is
60 - 65~6 of the maximum metal yield. At low pH the current is consumed for
hydrogen reduction and liberation. In the descending branch of the curve
Card 1/3

3/076/61/035/,jGV-~~02/619
Polarization during .... B127/B208
the current is consumed for the metal deposition. The discharge of Ikydro-
gen ions is promoted in that part of the curve which corresponds to hydro-
gen liberation, the reduction of the metal ions in that part of the curve
which corresponds to metal deposition. The curves are exactly explained in
the papers by A. N. Frumkin, Zh. fiz. khimii, J1, 1875, 1957, Z. Phys.Cidm,
M, 321, 1957, and I. A. Bagotskaya, Dokl. AN SSSR, la, 343~ 1956. 110,
397, 1956. Apparently hydrogen deposition is facilitated on an electrode
coated by hydrogen. Thi 's is confirmed by the paper by M. Smyalovskiy
saying that there is a relationship between the hydrogen overvoltage and
the tendency of the cathode metal toward supersaturation with hydrogen.
The'following reactions are assumed to take place at the hydrogen-coated
electrode: H30+ + Hads + e ----!~H2 + H20 and H 30+ + e -;;' Hads+ H20.
The rate of the first is higher than that of the latter. The increased
metal reduction with decreased rate of hydrogen deposition is probably
due to the fact that the metal deposition at a surface saturated with hy-
drogen is far more difficult than at a hydrogen-free electrode surface.
pH 3.0-3.5 is most suitable for the metal deposition. The retardation of
the metal ion reduction is probably related to an adsorption of foreign
particles, hydroxides and others, which are deposited on the surface of the

iron electrode after breaking the contact, and passivate the electrode. A
potential jump is observed at the moment of connection. By adding aluminum,
polarization of the cathode increases only at pH 2-2.5. Aluminum sulfate
inhibits the deposition of the metal, but does not affect H2deposition.

determined are widely scattered and not reproducible, but above -120
reproducible values are obtained and above 200 0C the potential agrees
with the calculated value to an accuracy of -0.02 v. It is concluded
that above 2000C there is no adsorption of impurities and no irreversible
adsorption of hydrogen and that owing to the absence of adsorption the
deposit is free of internal stress. Therefore nickel at high temperatures
behave-, like a reversible electrode. This is also confirmed by the
absence of polarization at high temperatures. The temperature coefficient
of the potential agreed with the data by A. J. de Bethune, T. S. Licht
and N. Swendeman (J. Electrochem. Soc., 106, 616 (1959)). From this, the
standard potential of the nickel electrode at 250C was calculated as
being -0.270�0.005 v in relation to a standard hydrogen electrode, which
deviateo by 0.015 - 0.025 v from the value calculated on the basis of the
thermodynamic data. There are 4 figures.

TEXT:' The effect of passivation on the elebtrodeposition of nic kel was

Results: The overvoltage of nickel referred to a steady potential at low

on current density is observed at high temperatures. Ni deposition at
high temperatures does not cover the entire electrode surface but occurs
only in spots; hence the overvoltaGe as measured refers to much higher
current densities than those calculated from the electrode area.
Conclusions: The alight dependence of polarization on current density
at high temperatures is due to the area of deposition becoming larger as
current density increases, and in fact the current density remains nearly
unchanged. The deposition area adapts itself to the polarization current
just as is the case with metals deposited at low overvoltage. 'Mien the
polarization curve is plotted quickly, this self-adaptation is not given
time to occur. There is no essential difference in the mechanism of metal
deposition as between high and low overvoltages. The transition from
coarse-crystalline deposits at high temperature to fine-crystalline at
low temperature is due to the quicker paBsivation in the latt*er, which also
results in higher overvoltage. At high temperature, a diffusion zone
impoverished in nickel appears near the growing deposit of nickel. The
concentration overvoltage of Ni at 1800C is calculated from the thickness
of the diffusion layer: it is about 15 mv at a current density of
10 ma/cM2. There are 2 figures.

the same. The literature on the potentials for solid and liquid gallium is
contradictory and shows differences of as much as 170 millivolts. The stationary
potential of solid and liquid gallium in alkaline solutions of potassium gallate
was determined in the 7-38 C temperature interval with electrodes of two designs
(fig. 1.); the potential curves are shown in fig, 2. The change in voltage noted
with one electrode la is attributed to penetration of the electrolyte to the
platinum contact, forming a Ga-Pt macroccll. Readings with the glass encapsulated
electrode 1b show the voltagc does not change from 7-29 C (-1.632 v.), then there
is a slight change to -1.638 v, a drop to -1.636 v, and then no change from

30-38 C. The cause for this change of 4-~6 millivolts was not determined. The
discrepancies in the literature are attributed to improperly act up experiments
in which the electrode structure was faulty. Orig. art. has: 2 figures.
