TITLE: on a Method of--Clrmputing the Deposition of Disperse Particles
From a Flow on an Obstacle (K metodike rascheta osazhdeniya

PERIODICAL: Kolloidnyy zhurnal, 1958, vol XX, Nr 3, pp 326-526 (USSR)
ABSTRACT: In the physics of aerosols the problem of the seposition of
aerosols from a flow on an obstacle is very important. For
the calculation of the particles deposited in the time unit
on the obstacle, it is sufficient to determine the coeffi-
cient of capture E equal to the relation of the cross section
of the flow to the largest cross section of the obstacle. If
the inertia of the aerosol or colloidal particle circum-
venting the obstacle is negligible and the fieli of external
forces is solenoidal, then the computed concentration of the
particles along their trajectory is constant. This theorem
permits, in a simple manner, the calculation of the deposition
speed of particles on obstacles, e.g, emerging bubbles or
descending balloons.

PERIODICAL: Xolloidnyy zhurnal, 1958, vol 20, Nr 6, PP 705-707 (USSR)
ABSMICT.- On the mobile interface of two media, of which at least one
is an electrolyte, an ordinary (diffusion) electrical double
layer appears due to the interaction of diffusion and ionic
migration in an electric field. There is also a secondary
(diffusion) electrical double layer arising from the inter-
action between convective diffusion and ionic migration in
an electric field. The charge of the inner layer is due
to deviation from electrical neutrality. The charge of the
oliter layer is located in tho electrolyte layer adjacent to
the interface and is equal in magnitude and opposite in
sign.
There is 1 Soviet reference.

possible to apply the corresponding B-4 law to small distances.

TITLE: The Electron Theory of the Adhesion of Metals Connected

ABSTRACT: Hitherto, the double layer and the adhesion forces
of a thin semiconducting sheet (which is inclosed
between two different metals) have been investigated
only qualitatively. The authors use the mathematical
analogy of this problem with the problem of the
electrostatic interaction of two differently char&ed
surfaces which are separated by a electrolyte layer.
This paper deals only with the case in which there are
only carriers of one kind in the semic--iductor. Only a
small part of the impurity centers is assumed to be
Card 113 ionized. In this case, the equilibrium distribution of the

The Electron Theory of the Adhesion of Metals Connected SOV/2o-121-5-R)1/50
by'a Semiconductor Layer
charCes is determined by the equation of Poisson (Puasson) -
Boltzmann (Bolltsman). The adhesion force of the film
with respect to any metal is equal to
2 2
F=e E boundary /Sn where Eboundary denotes the field
strength within the semiconductor on the boundary
with the corresponding metal. The problem, therefore,
consists of the determination of E on the right and
left boundaries of the films. Then boundary conditions for
the above mentioned Poisson-Boltzmann equation are
given explicitly. This equation together with the
boundary conditions is absolutely equivalent to
the corresponding problem in the theory of the hetero-
coagulation of colloids for the interaction through
a binary symmetric electrolyte. A certain difference
between the 2 analogous metals is then discussed. By
a variation of the thickness of the film the adhesion
force is changed equally for both of the metals. The
mathematical calculations may be carried out as in the
Card 2/3 papers on the theory of heterocoagulation. The adhesion

of' the film incrqases monotonously if H decreases.
The following interesting conclusion may be drawn
from the above given considerations: If the thickness
of the film (enclosed between 2 different metallic
surfaces) is adequately diminished, the density of the
double layer (and therefore also the adhesion forces) Carl,
always be increased. There are 4 figures and 4 re-fer-
ences,&Uof which are Soviet.

ABSTRACT: On the basis of various earlier papers the authors first
give a short report on the present stage of the problem. It
is known that the surface states of semiconductors can be
produced by stripping of the periodic structure (surface
zones by I. Ye. Tamm) and by the presence of a large number
of impurity centers on the surface. In the scheme investigated,
the surface levels of the second type (surface zones accord-
ing to I. Ye. Tamm) are taken into account, and the presence
of 2 types of surface states (donors and acceptors) is assumed.
This scheme agrees essentially with that of V. Bratten and
J. Bardeen (Dzh. Bardin) (Ref 4). The model used in this case

of a single type. To be precise, an electron-semiconductor
is investigated. The position of the surface levels is shown
by a schematical drawing. This scheme corresponds to a nega-
tively charged sur-face. A second drawing shows the d-zone-
scheme for the case in which contact between the semiconductor
and the metal is established through a narrow gap. Another
case is, however, possible, in which electric field strength
has different signs on the two sides of the semiconductor
surface. According to the authors' opinion, it is convenient
to subdivide all cases of contact between a semiconductor
an a metal into two groupsz 1) The electric field has the
same direction on both sides of the semiconductor surface;
2) It has different directions. Calculations are followed
step by step and numerical results are given by a table.
Field strength in the gap increases rapidly with an increasing
number of centers. At the point of contact fields occur
which cause an adhesive fo ce amounting to a two-figure

Factors, besides the viscosity of the liquid , which affect coating thick-
ness are considered: a) wetting kinetics as a function of the formation
speed of a meniscus between the emulsion surface and the film base; b) the
radian angle (formed by the meniscus) on the rate of flow of the meniscus,
including the case at high film-base speeds where the radian angle reaches a
limit value of 1800 and begins to degrade the completeness of contact be-
tween the liquid and the film base; etc. Besides theories on the production,
application, and check of coatings, methods for physicochemical investigations
and wetting and non-wetting phenomena during the application of coatings are
studied. A theory based on the attractive forces between liquid and film base
is set forth and results are discussed. 0. K. Smirnov assisted in compiling

ABSTRACT: The authors distinguish two stages in the attachment of a
mineral particle to a bubble -L'n flotation. In the first
stage the parti.-le approaches the bubble surface so
closely that forces promoting or hindering adhesion can
develop, This stage has not previously received attention,
and the authors now give a theoretical treatment3, following
the extensive work of one of them (Deryagin) in this field.
They conclude that if "tarbulization" (setting in
turbulent motion) of the pulp and deviation of the bubble
and mineral-grain shapes from spherical are ignored and
the treatment is restricted to grains small compared with
the bubbles the problem becomes similar to the trapping of
Card 1/3 mist droplets. They discuss the influence of the ratio of
the particle size -to the minimum size at which contact due

solely to inertial forces is still possible, and of the
values of the Reynolds number and another dimensionless
group. The second stage, in which the particle becomes
attached to the bubble, they show to depend on the point
of contact and the contact velocity and give equations
and data for the calculations. The equations obtained
for the probability of contact are necessary for calcula-
ting the rate of flotation. Since the particle diameter
greatly affects this probabilityg the authors emphasize
that in considering the selectiveness of flotation the
degree of dispersion of particles must be allowed for;
Card 2/3 this may be done by using the equations given.

this the papers by D. M. Tolstoy, S. V. Nerpin, 1. P. Yefremov are
mentioned. A. N. Fr=kin and B. N. Kabanov emphasized for the first
t~jne the importance of the thin liquid layers between bubbles and
mineral particles. S. S. Dukhin and the author of the present paper
pointed out the existence of an electric interaction between the
moving bubbles and the particles and refer in this connection to tb~
papers by A. N. Frumkin, V. G. Levioh (foatnote 5). By means of the

TITLE: Determination of the Specific Surface Area of Powders
in the Production of Hard Alloys
PERIODICAL: Tsvetnyye metally, 1959, Nr 11, PP 5f~-60 (USSR)
ABSTRACT: This work has been carried out in order to see whether
it is possible to determine more accurately the
specific surface of powders by using relatively simple
methods. The following gas porosi'ay methods were
used: Carman's method, using Poiseil's system of gas
flow through a layer of powder, and B.V. Deryagin's
method with Knudsen's (molecular) system. The
results of the determination of the specific surface
area by the gas porosity me'Ghods were compared with
those of the methyl alcohol vapour adsorption metdod.
The low temperature adsorption of nitro:,-en method used
by Brunauer (Ref.1) was used as thE Control method for
the determination of the specific surface area of
powders of below 10~L grain size. The specific surface

,ranulometric compositions which can be determined by
means of a microscope. In this article the practical
results of the application of the four above methods
for the determination of the specific surface area of
powders in the manufacture of hard alloys are given.
The determination of the specific surface area of
H2WO 41 WO 3' W, WO, Ti02; TiCWC, Co powders and a VK6A
mixture (mixture of WC and &,6 Co powders) using
ioiseills system of gas flow across the specimen (in
the form of a compressed tablet of powder) was carried
out in an apparatus designed for the measurement for
the specific surface area of powders by Carman's
method. In practice the results of the determination
of the specific surface area are usually converted to
average diameter or grain size, assuraing that the
particles have a spherical shape. In Table 1, grain
sizes of powders are shown for different porosities.

apparatus. Besides, any adsorption method giving the
total surface area of particles gives an incorrect
powder grain size value in the case of particles with
internal pares. This method proved to be useful for
the selection of a simpler and easier method, by
comparing the values of specific surface obtained by
this method with those obtained by other simpler
methods. 2. It has been shcwn that the methods and
instruments which are based or. the filtration of air
at atmospheric pressure and UE-e C02;eni-Carman's formula,
give incorrect lower values fcr the specific surface
area of powders of high and medium dispersion. These
methods can only be used for the determination of the
specific surface area of coar,--ely dispersed po-wders.
3. The determination of the specific surface area of
powders by the resistance to filtration of discharged
nitrog en (Deryagin's method) is the most convenient.
This method and the apparatus based on it, enable the

powders of hard alloys to be determined quickly and
sufficiently accurately and the average particle size
to be calculated. This is extremely important in the
manufacture of hard alloys. This method is
theoretically well-founded and in practice enables
the external specific surface area of different powders
of any degree of dispersion from a particle size of
1001i and less onwards, to be measured without limitation.
Therefore this method can be successfully applied for
the determination of the specific surface area and

Pp 1521 - 1528 (USSR)
ABSTRACTs The results published by Obraimov and Lazarev, and various
Western authors aria supplemented ba, a number of experiments.
The authors first measured the charge density resulting from
the Kerr effect in nitrobenzene, which had been introduced
into the crystal o:mok (for the de,rioe see figure 4). The
mean charge density of Hama auscovites and Aldan phlogopites
did not exceed 50 absolute charge units per cm2. In some sur-
face sections the charge density of muscovite and phlogopite
attained 200-250 and 300 absolute charge units per cm2, re-
speotively. The potentials occurring in the cleavage planes
are measured by melLne of fixed and movable probes of different
size (for the device and measuring arrangement see figure 5).

mosaic with elementary surface < 1 mm2 and a mean charge
density of 20 absolute charge units per cM2 is formed in
the new crystal planes. Figure 6 distinctly shows the abrupt
behavior of the potentials. The charges effected at the
instant of crystal cleavage w*:r* measured by means of an
oscilloscope. The authors obtained also for this case *50
absolute charge units per OM2. When the crystal is cleft
in humid air, the charge recorded depends on the cleavage
rate (cf. Fig 8). When the cleavage rate increases and humi-
dity drops, the actual charge density on the cleft face rises
and approaches a limit a0, which has a characteristic value
for each crystal. If the crystal is cleft in a medium of a
small degree of eurface conductivity, or if the cleavage
rate is high, the mosaic charge density does not vary through-
out the cleavage and retains the value do# The electrostatic
part of the cleavage then reaches a maximum, it may be defined
