The theory and ways of applying a new electroanalytical detectior
method were developed. The method, called galvanovoltammetry,
consists of the measurement of current from the bipolar electrode of
a three electrode cell which consists of a working electrode and a
counter electrode, between which a constant current is applied, and...
The extraction of tantalum fluoride complexes by large cationic
extractants (tetraphenylarsonium ion, TPA, and crystal violet) and
by methyl isobutyl ketone (MIBK) has been investigated as a function
of fluoride concentration using ¹⁸² Ta as tracer. Extractions by the
cationic extractants into chloroform were carried out in the absence
of...
The purpose of this research was to study the impact
phenomena of a tennis ball striking a hard surface.
Stroboscopic photography was used to collect the ball's
impact images from seven angles of incidence, ranging from
-23 degrees to -70 degrees with zero, top and back initial
spin respectively.
Through...
New alloys containing refractory metals have been developed
by the aero-space industry to meet the demand for thermally resistant
materials. The chemical analysis of these alloys has been
handled successfully by the use of ion exchange. Hydrofluoric acid,
either alone or combined with hydrochloric acid, has here-to-fore
been used to...
