"Kolloid Zhur" vol xii, No 0'". pp 4-u-447
Measured adhesion of fine quartz filaments in
aqueous media using Deryagin's formula to cal-
culate specific adhesion energy. Values cb=
tained correspond closely to Bradley's for
adhesion of quartz spheres in air. In air
adhesion energy Is independent of duration of
contact; in water it grown slowly from
to equilibrium value approximately-equal to
value in air. Tim for reaching equilibrium
value is decreased by addition of electrolytes
(increased cation charge) and as tenperatvwe
is increased. Between 30-430C this time drops
sharply from days to 1 hr. Adhesion kinetics
are not affected by time of f ilament immersion

together. Slow separation requires 10-154
less force than rapid. Apparently hydrate
layers covering filaments are gradually "de-
stroyed" after contact period. Absence of
these kinetics for contact in air and simi-
larity of specific energies for contact in
water and in air Indicate In both cases fila-
ment surfaces enter into "direct" contact or
are separated by identical boundary layer of
water. Addition of hi&h concentration of
acetone stabilizes hydrate layers and reduces
adhesion energy to zero. Explains effect of
solvation on 1yophilic dispersed systems and
has applications in technological processes.

Abstract The phyiical aspects of adhesion, which takes place during the con-
tact of turo solid bodies in the presence of an external gaseous
or liquid medium, are discussed. It was determined., tbrough prac-
tice, that, adhesion depends largely uTc1n the nature of the functional
groups included in the composition of the adhesive layer as well as
upon the cbemically active atoms and radicals present in this layer.
The effect, of individual active-aton,5 or groups of atoms, which.are
present In the adhesive layer and may enter into an electron chemical
bond on the conversion of electrons from one phase into another,
is explained. Drawings.

Periodical Zhur. tekh. fiz. 24, 1354-1357, Jul 1954
Abstract Letter to the editor. Criticize the article on adhesion by M. S.
Skinner et al. (J. Appl. Phys. 24, 438 (1953)) as repeating the
subject which they themselves published six years ago (Deryagin
et al., mN 61, 849 (1948)). Seven references, including 2
foreign.

Title : Adhesion-of high-polymers to glass and its dependence upon pressure and
nature of the surrounding gas medium
Periodical t Dokl. All SSSR, 97, Ed. 3, 475 - 478, July 21, 1954
Abstract : A method of determining the discharge potential, discharge gaps and sur-
face density of electrization, by stud- ng the polymer-gl&ss adhesiograms,
Yi
is described. The effect of pressure and nature of the surrounding gas
on the adhesion of high-pDlymers to glass was determined by the Paschen
law. By studying the effect of various factors, including the molecular
structure of the adhesive and liner, i-i is possible to make a rational
selection of gluing and lEkcquer forming polymers and form conditions
increasing the adhesion. Eight USSR references. Graphs.

Title I Optical investigation of the adsorption and surface condensation
of vapors close to the saturation point
PerioditiLl Dok. AN W'SSR 98/1, 93-96, Sep 1.% 1954
Abs,tract Polymolecular adsorption and condensation of vapors of n-alcohols,
water, CGl4j benzene, etc., on smooth surfaces were investigated
to datermiTie the phase conversions taking place between the
volune and liquid layers close to the wall of the test vessel.
The device used in this optical investigation is described. The
adsorption on smooth surfaces in a range of relative pressures
higher than 0.95 - MY7, was found to be of a polynolecular
nvture. In other pressure ranges the adsorption acquires a
mono- or bimolecular nature. Ton references: 9-USSR and 1-German

Abstract j The) dovalopnent of an ion-electrostatic theory, regarding the repulsion
forces in electrolyte layers between uniformly and non-uniformly charged
surfacefl, is discussed. The formmlation of the first quantitative physi-

Title tEquilibrium, stability and kinetics of free liquid films
Paricwlical 1Dok. AN 3,13SR 99/6, 1029-1032, Dee ~1, 1954
Abstraot iThe method and rhathematical formulas applied in determining the equilib-
rium, stability and kinetics of free liquid films, are described. The
stability of a liquia film investigated in this report pertains to the
rupture or 5harp increase in the thickness of the film down to such val-
ues where t1le stability of the film can be secured by its elasticity conn-
ected with the propertis of adsorption mono-layars. Equilibrium of the
film was found to be of a timely nature depending upon the kinetic process
of slow settling of the film up to a point when it reaches a critical
thickness at which it loses its stability. Eight references: 7-Li.31-R and
