Macro-segregation in aluminium alloy sprayformed billets
Autor: P.W. Alexander, Ian Graham Palmer, K.P. Mingard, John White, Brian Cantor, Treve Courtney Willis, I. R. Hughes
Publikováno v: Acta Materialia. 48:2435-2449
It is generally assumed that during sprayforming the amount of micro- and macro-segregation in the sprayforms will be limited or absent because of low liquid fractions, small grain size and high cooling rate. This paper shows that macro-segregation c

Polarographic determination of total serum protein
Autor: L.E. Smythe, R. Hoh, P.W. Alexander
Publikováno v: Journal of Electroanalytical Chemistry and Interfacial Electrochemistry. 81:151-159
The total serum protein is accurately determined with high sensitivity by a catalytic polarographic method with trans -dichloro-bis(N,N′-dimethylethylenediamine) Rh(III) chloride as reagent. It is shown that microlitre serum samples can be analyzed

D.C. and pulse polarographic studies of rhodium(III)-protein catalytic systems
Autor: R. Hoh, P.W. Alexander, L.E. Smythe
Publikováno v: Journal of Electroanalytical Chemistry and Interfacial Electrochemistry. 80:143-153
The Rh(III) complexes of substituted ethylenediamines are observed to be catalytically active at the DME and studies of the effects of human serum proteins on this activity are reported. Rh(III) complex waves are shown to respond to six different pro

Trace determination of platinum—I. A catalytic method using pulse polarography☆
Autor: L.E. Smythe, R. Hoh, P.W. Alexander
Publikováno v: Talanta. 24:543-548
Experimental conditions are given for the development of a well-defined catalytic polarographic wave for PT(II) after chelation with ethylenediamine. Direct-current polarographic studies of the wave characteristics indicate that it is of the catalyti

Trace determination of platinum—II. Analysis in ores by pulse polarography after fire-assay collection
Autor: P.W. Alexander, R. Hoh, L.E. Smythe
Publikováno v: Talanta. 24:549-554
A pulse-polarography method is described for the determination of traces of platinum in ores after fire-assay separation and preconcentration. The silver bead from the fire assay is dissolved and treated with ammonia and ethylenediamine to produce a
