The Inference of Adsorption from Differential Double Layer Capacitance Measurements (open access)

The Inference of Adsorption from Differential Double Layer Capacitance Measurements

From Abstract : "Dependence of boundary tension and capacitance at the mercury-aqueous 0.1 N HClO4 interface on polarization and organic solute concentration were determined for the colutes n-amyl alcohol and phenol. ... An earlier treatment proposed by this Laboratory based on a (non-thermodynamic) assumption of linear variation of surface charge density with coverage appears adequately justified for inference of fractional surface coverages near the electrocapillary maximum, but must be considered approximate for evaluation of molar area at full coverage in cases where linear variation of charge with coverage has not been demonstrated."

High Purity Calcium (open access)

High Purity Calcium

Technical report. From Introduction : "For more than a century, methods employed in preparing calcium were based largely on electrowinning and the most successful were based on [Sir Humphrey] Davy's process. ... In general, the metal was of adequate quality for the industrial applications of the time, and although by 1940 some strides had been made in the purification of calcium, interests in the better grades of the metal were limited essentially to experimental work of academic concern."

Design and Test of a Diaphragm Pump for Liquid Metals (open access)

Design and Test of a Diaphragm Pump for Liquid Metals

Technical report. From Abstract : "Details are provided on the construction and operation of a two-stage diaphragm pump successfully used for the first time in liquid metal service. From the results of 5,376 hr. test of the pump it was concluded that it is well suited to the pumping of liquid metals at low flow rates where pulsating flow can be tolerated and also where remote operation is required. Operating temperatures and pressures are limited only by the availability of suitable materials of construction."

Measurement of Thermal Properties by the Arc Image Furnace

Technical report. From Abstract : "A number of imaging furnace systems and sources are discussed with emphasis on the carbon arc image furnace. Several potential applications of the carbon arc image furnace in high temperature research are described and a new method of heat capacity determination is discussed."
