Abstract Beim Abbau des Polymethacrylsäuremethylesters durch Ultraschallwellen entstehen langkettige freie Radikale, die mit gleichzeitig vorhandenem α,α‐Diphenyl‐β‐pikryl‐hydrazyl (DPPH) reagieren. Erfolgt der Abbau unter Ausschluß von Sauerstoff, werden pro gespaltene Bindung zwei Moleküle DPPH verbraucht. Spektrosk…
Alloying elements commonly found in steel were added to pure iron to establish their effect on hydrogen overvoltage and corrosion rate in 0.1 M citric acid ( p H 2.06), 0.1 M malic acid ( p H 2.24), and 4% sodium chloride at p H 1 and 2. Sulfur, phosphorus, and carbon proved detrimental to corrosion resistance. Copper…

Horobetsuite occurs associated with free sulphur and iron sulphide minerals, in the sulphur deposit of Horobetsu Mine. The chemical formula of horobetsuite has been determined as (Bi, Sb)2S3. The molecular ratio of Bi2S3 to Sb2S3 varies between 9:11 and 13:7. The mineral is intermediate between bismuthinite and stibni…

The microwave magnetic field in a small ferrite sphere and thin circular cylinder is found in first approximation. In a circularly polarized exciting field the internal field is again circularly polarized. The ratio of the internal field to the exciting field is 3(µ±α+2)-1 for the sphere and 2(µ±α+1)-1 for the cylinde…

High purity aluminum was anodized in sulfuric acid solutions at various concentrations (5– 50%), temperatures (10°– 50°C), time periods (2 – 60 min), and current densities (1.7 – 6.2 amp/dm 2 ). The coating weight, metal loss, coating ratio, sealing weight gain, dyed color, density, and coating chemical dissolution ra…
Measurements have been made on the thermoelectric power of several nickel oxide samples containing foreign ions. Using an energy model recently proposed for nickel oxide, the effect of the nature and concentration of additions on the Fermi level, hole concentration, and mobility is derived and discussed. For most of t…
After a historical introduction the general principles of the magnetic cooling method are outlined. First, the case of the ideal paramagnetic salt is treated, and this is followed by a discussion of the electric and magnetic interaction effects which cause departures from ideal behaviour, and set a lower limit to the…
Abstract Theoretical considerations are presented for the evaluation of the free energy change that accompanies an exchange of cations between a clay and a solution. Also, a means is proposed for characterizing the effective concentration of the ionic atmosphere of a substance that exhibits cationic exchange. Results…
The amount of sulfate found in anodic coatings formed on pure aluminum anodes in sulfuric acid electrolytes increased as the current density and concentration of acid increased, but decreased as the temperature was raised. Chemical analysis showed that the coatings consisted substantially of Al 2 O 3 and SO 3 with pra…
