BACKGROUND The role of palladium and nickel sensitization in oral disease and dermatitis is not fully understood. OBJECTIVES To investigate whether sensitization to these metals was associated with exposure to dental alloys and oral and skin complaints/symptoms in a European multicentre study. METHODS In six dermatology clinics, patch tests with palladium (3% Na2 PdCl4 ; Pd = 102.0 µmol/g) ...

The adsorption of n-alkanethiols onto polycrystalline thin films of palladium containing a strong (111) texture produces well-organized, self-assembled monolayers. The organization of the alkane chains in the monolayer and the nature of the bonding between the palladium and the thiol were studied by contact angle measurements, optical ellipsometry, reflection absorption infrared spectroscopy (R...

Two nanocrystalline palladium-supported tin oxide catalysts for water denitration were synthesized by a modified sol–gel technique using appropriate chloride precursors for both support and active phases, and citric acid to tune the rate of hydrolysis and condensation. The difference among sample preparation procedures refers to the moment of the noble metal loading to the support, as well as t...

The title compound, [PdCl(2)(C(8)H(11)O(2)P)(2)], has a comparable structure to those of related palladium dichloride complexes containing trimethyl phosphinite and methyl diphenyl phosphinite. The Pd atom is located on a crystallographic twofold rotation axis: thus, there is just one half-mol-ecule in the asymmetric unit. The structure is isomorphous with the platinum analogue cis-[PtCl(2){P(O...

Series of alkali and alkaline earth promi=oted palladium-alumina (Pd/Al2O3) catalysts were synthesised by incipient wetness method using palladium acetate dissolved in acetonitrile as a precursor for palladium. The dispersion on the catalyst surface was calculated from chemisorption CO molecule. tested under vapour phase hydrogenation phenol to cyclohexanone down-flow reactor at atmospheric pre...

Hydrogen in metals has possible applications in various energy storage devices. For the palladium-deuterium system, excess power production and other anomalous effects have been reported. This study focused on hydrogen and deuterium insertion into palladium and deuterium insertion into various palladium-boron alloys. The condition of the metal surface is a major factor in the insertion of hydro...

The adsorption and reaction of formic acid, HCOOH, on monolayer and multilayer palladium supported on a Mo(110) surface have been studied using temperature-programmed desorption (TPD) and high-resolution electron energy loss spectroscopy (HREELS). On multilayer palladium, formic acid adsorbs molecularly at 100 K and desorbs primarily intact upon heating to 200 K. A small amount of the adsorbed ...

Flexible palladium-based H2 sensors have a great potential in advanced sensing applications, as they offer advantages such as light weight, space conservation, and mechanical durability. Despite these advantages, the paucity of such sensors is due to the fact that they are difficult to fabricate while maintaining excellent sensing performance. Here, we demonstrate, using direct nanoimprint lith...

Early studies have focused on the synthesis of palladium nanoparticles within the periplasmic layer or on the outer membrane of Desulfovibrio desulfuricans and on the S-layer protein of Bacillus sphaericus. However, it has remained unclear whether the synthesis of palladium nanoparticles also takes place in the bacterial cell cytoplasm. This study reports the use of high-resolution scanning tra...
