Phytochemical based synthesis of palladium nanoparticles by bioreduction of medicinally potent plant extract Coleus amboinicus is investigated in the present study. Treatment of palladium chloride with Coleus amboinicus extract resulted in the formation of palladium nanoparticles. The formation of palladium nanoparticles were confirmed using UV-vis, FTIR, TEM and XRD. Polyols such as flavones, ...

In a palladium-catalyzed oxidative esterification, hydrosilane can serve as an activator of palladium catalyst with bismuth, thus leading to a novel ligand- and silver-free palladium catalyst system for facile oxidative esterification of a variety of benzylic alcohols in good yields.

Background: One of the key techniques for the preparation of 125I seeds is adsorption of 125I onto silver bits coated by palladium (pd). Carriers played an important role in the adsorption of 125I on palladium. KI is used as a carrier for fixing of 125I onto silver wire bits coated with palladium. Materials and Methods: Three procedures KI, KOH, NH4OH were investigated for adsorption of ...

Using ab-initio calculations and kinetic Monte Carlo simulations, we demonstrate that the deposition geometries of palladium are strongly dependent on the polarization direction of the LiNbO3 substrate. Different stoichiometries and atomic structures of the positively and the negatively polarized substrates cause substantially different bonding configurations of palladium and energy barriers fo...

A Pd-encapsulated graphite electrode was used as the negative electrode in Li-ion cells. Through dispersion of ultrafine nanoparticles of palladium on the surface of graphite, the interfacial properties of the carbon surface were modified. The presence of the palladium Ž . dramatically reduces the initial irreversible capacity of the graphite in propylene carbonate PC -based electrolyte. Pallad...

the cross-coupling reaction between phenylboronic acid and various types of aryl halides (suzuki reaction) was carried out using a catalytic amount of a new palladium catalyst (1-benzyl-3-(1-benzyl-1-methylpyrrolidin-1-ium-2-yl) pyridin-1-ium palladium chloride [dbnt][pdcl4]) in poly (ethylene glycol) (peg-200) in the presence of koh as the base. this new catalyst was synthesized and characteri...

In this work the field ion microscopy technique was used in order to examine hydrogen-induced changes in palladium surface structure in the context of surface palladium hydrides formation. The goal of the study is to determine the crystallographic planes on which the particles of interest are formed with greatest intensity. Employing a method which consists in finding the differences in the bri...

A large collection of palladium samples, supplied by IMRA Materials (Japan), were studied to determine the relationship between energy production and various properties including the amount of excess volume, the open-circuit-voltage, and the maximum D/Pd ratio. The following conclusions result from the work: 1. Palladium, no matter how well prepared, is very inhomogeneous with respect to the pr...

The exceptional activity for methane combustion of modular palladium-ceria core-shell subunits on silicon-functionalized alumina that was recently reported has created renewed interest in the potential of core-shell structures as catalysts. Here we report on our use of advanced ex situ and in situ electron microscopy with atomic resolution to show that the modular palladium-ceria core-shell sub...

A ligand free, Palladium nanoparticles catalyzed synthesis of pyran derivatives using C-H activated compound, malononitrile and aryl aldehyde via Knoevenagel condensation followed by Michael addition reaction using Palladium nanoparticles as catalyst in one-pot is described herein. The advantages of this method lie in its simplicity, low catalyst loading, cost effectiveness and easy to handle. ...
