In order to investigate the anomalous deformation of palladium metal during hydrogen absorption and desorption cycles we measured the dynamical changes of the bending and extension of a palladium plat...
Novel 1,3-dialkylimidazolinium and 1,3- dialkyltetrahydropyrimidinium hexafluorophosphate salts as N-heterocyclic carbene precursors were prepared by reacting N,N'-dialkylethandiamine or N,N'-dialkylp...
A novel concept of simultaneous injection-effective mixing analysis (SIEMA) is proposed, and a SIEMA method applied to the spectrophotometric determination of palladium using a water-soluble chromogen...
A new solid phase, nanoparticles of alumina functionalized with pyridine groups, was synthesized and used for extraction and preconcentartion of palladium(II) ions from some water samples. The effects...
Iron oxide-alloy equilibration experiments were conducted in H2 -CO2 gas mixtures at 1 atm and 1125–1240 °C using strips of Au74Pd26 (wt%) and produced Au-Pd-Fe alloys with 0.03–13 wt% iron. ...
The effects of pore structure of the support on the plating morphology, thickness, and composition were investigated in an electroless plating procedure. Some of the plating studies were carried out d...
Pd-Si-structured novel mesoporous nanocomposite catalytic materials, having quite high Pd/Si ratios, were synthesized by an acidic direct hydrothermal synthesis route. The nanocomposite catalytic mate...
A highly effective, easy to handle and environmentally benign process for a palladium mediated Heck reaction was developed. The in situ prepared 3-component system, Pd(OAc)2 / 1,3-dialkylbenzimidazoli...

In this study, we have employed the Interacting Boson Model-2 (IBM-2) to determine the most appropriate Hamiltonian for the study of palladium nuclei. Using the best fit values of parameters to constr...
A new chromogenic reagent, 2-(2-quinolylazo)-5-dimethylaminoaniline (QADMAA) was synthesized. A sensitive, selective and rapid method for the determination of palladium based on the rapid reaction of ...
Angular distributions for the inelastic scattering of 13.0 MeV deuterons on 104;106;108;110Pd were measured with the S˜ao Paulo Pelletron-Enge-Spectrograph facility in the range of 120 · µl...
