Biofilm as a versatile stablizer and promoter for Pd nanoparticle (PdNP) recovery and catalytic denitrification

Zhou C., Rittmann B.E., Wang Z., Ontiveros-Valencia A., Krajmalnik-Brown R., Arizona State University, US
There is an increasing demand on recycling of palladium from mining waste streams for purposes of resource retrieval and catalytic application. We introduced the novel H2-based membrane biofilm reactor (MBfR) technology to recover Pd in [...]

Colloidal Palladium Nanoparticles versus Commercial Palladium Catalysts for Suzuki Cross Coupling Reactions – The Influence of Surface Functionalization

Collins G., O’Dywer C., Holmes J.D., University College Cork and Tyndall National Institute, IE
The Suzuki-Miyaura reaction is a highly utilised reaction for aryl-aryl bond formation in organic synthesis due it is versatility. The motivation for the application of heterogeneous catalysts in these systems is the easy recovery and [...]

Chemiresistive hydrogen (H2) gas sensor based on viral-templated Pd nanowires

Moon C.H., Yan Y., Zhang M., Myung N.V., Haberer E.D., University of California Riverside, US
Palladium (Pd) has been widely used for H2 sensing applications because it readily forms a solid solution with hydrogen, modifying electrical resistance. Because the resistance change is diffusion-limited, Pd nanostructured materials with large surface area [...]

Synthesis and Characterization of a Novel Palladium Nanostructured Ensemble Supported in Anodized Alumina Membranes for Hydrogen Sensing Applications

Méndez-Colberg H.G., Martínez-Iñesta M.M., University of Puerto Rico, Mayaguez Campus, US
A Pd/Anodic alumina membrane (AAM) ensemble was formed by using Solid State Reduction. The ensemble consisted of Pd thin films on both sides of the AAM with connecting nanowires as evidenced with Scanning Electron Microscopy [...]

Controlled Synthesis of Subnano Pd Cluster Catalysts by Fine Tuning of Dendrimers

Mizugaki T., Kibata T., Maeno Z., Mitsudome T., Jitsukawa K., Kaneda K., Osaka University, JP
We recently succeeded in the fine control of the Pd cluster sizes in wide range using the fifth generation poly(propylene imine) (PPI) dendrimers. Preorganization of Pd ions within the PPI dendrimer with butanediamine core(G5-C4) and [...]

Effects of Ag and Pd Addition on Mechanical Property and Ion-migration Tolerance in Low Temperature Sintering Bonding Using Ag2O Paste

Hirose A., Itou T., Ogura T., Osaka University, JP
We have proposed a new bonding process using Ag2O paste composed of Ag2O particles mixed with reduction agent of triethylene glycol (TEG). Ag nanoparticles formed at around 130℃ to 160℃ through the reduction process. Such [...]

Characterization of palladium nanoparticles embedded in a wool substrate

Fonseca-Paris C., Johnston J.H., Victoria University of Wellington, NZ
In the present paper we report the characterization of nanopalladium-wool fibre composites. Professor James Johnston and his research group at Victoria University of Wellington have developed a new methodology to reduce metal salts of palladium [...]

Wet organometallic chemistry for palladium nanoparticles synthesis performed in an organic media and under supercritical conditions in microreactors

Desportes S., Tidona B., von Rohr Ph.R., ETH Zürich, CH
Nanoparticles are been produced in a microreactor under different operating conditions, spefically under supercritical CO2. The known organometallic chemistry is been used to create Pd-nanoparticles. Compared to the batch process the processing time could be [...]

Nanopalladium – Wool: A Novel Fibre for Multifunctional

Fonseca-Paris C., Johnston J.H., Victoria University of Wellington, NZ
The development of new functional textiles based on composite materials of natural fibres and nanomaterials have become of increasing interest within both academic and industrial sectors. The inherent properties of their all precursor components can [...]

Palladium/Polymer nanocomposite based Chemiresistive SO2 Sensor

Meka D., Onbattuvelli V., Atre S., Prasad S., Portland State University, US
Here we present a highly sensitive nanocomposite based Chemiresistive SO2 sensor. The main objective of this research is focused on developing a cost effective, integrable and disposable gas sensor which detects SO2 gas molecules in [...]
