A number of diorganotin(IV) complexes with Schiffbase have been synthesized and characterized by elemental analysis, conductance measurements, molecular weight determinations, infrared, electronic and multinuclear magnetic resonance ((1)H, (13)C and (119)Sn NMR) spectral data. The molar conductivity data shows non-electrolytic nature of complexes. The bidentate nature of the ligands is inferred...

The electrical response of an electrolytic cell in which the diffusion of mobile ions in the bulk is governed by a fractional diffusion equation of distributed order is analyzed. The boundary conditions at the electrodes limiting the sample are described by an integro-differential equation governing the kinetic at the interface. The analysis is carried out by supposing that the positive and neg...

Systematic studies have been performed in order to achieve very high concentration of Hydrogen (or Deuterium) into a Palladium lattice. In a very diluted acid electrolytic cell a thin Pd cathode wire (100 m) and tick anode Pt wires (0.5 mm) has been used as electrodes in a coaxial geometry. Normalised resistance (R/Ro) of Pd-H wire system has been measured on-line and used as reference of H/Pd...

Hundreds of electrolytic loading tests of thin Pd wires in different experimental conditions have been performed in order to find out the best procedures for stable, high hydrogen overloading into the palladium lattice. In a very dilute acid solution thin Pd cathodes (50 or 100m in diameter) and thick Pt anodes (0.5 mm in diameter) were used in a parallel or coaxial geometry. Normalised resist...

Companion laboratory-scale studies were conducted on specimens of ESR alloy 718 in order to determine responsiveness of this material to several of the macroetching techniques used in the industry. The work developed from initial efforts to define the relative sensitivity to Alloy 718 segregation of the macroetchants in standard use at the respective locations of Into Alloys International: one ...
