The lack of availability of a single, complete paper on the
analysis of a digital data acquisition system for in situ oceanographic
measurements brought about the present work. In order to compile
an accurate technical paper on such a complex system, it was necessary
to design, construct, and calibrate a...
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...
As with many pairs of metals, the electrodeposition of Pb-Tl, Cu-Cd, and Cu-Ni at solid electrodes yielded partial polarization curves shifted from the polarization curves of the single metals. The curves for the more noble metals (Pb, Cu) were shifted negatively while the less noble metals'(Tl, Cd, Ni) curves were...
A continuous amperometric monitor for aqueous sulfite solutions
has been developed employing the electro-oxidation of sulfur (IV)
in 0. 1 M sulfuric acid at a glassy carbon test electrode. The monitor
employs a hydrodynamic flow cell, in which the solution stream
enters the cell through an orifice impinging on the...
A new pulse method for measuring differential double layer
capacitances has been developed in this work. The technique is based
on the determination of the cell time constant which, for an ideally
polarized test electrode-solution interface, is composed of the double
layer capacitance and solution resistance. By applying small step...
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...
Optimization of the galvanovoltammetric determination of dissolved
chlorine in a flowing stream was achieved through the use of
an analog computational device and improvements in the design of the
galvanovoltammetric cell and accompanying electronic circuitry. An
analysis system, applicable to industrial use over a range of flow
rates and dissolved...
