A new NIR fluorescent probe, NIR-Pd, for palladium species was designed and synthesized, based on a HD NIR fluorophore and deprotection of aryl propargyl ethers by palladium. The probe NIR-Pd displayed either a large NIR fluorescence turn-on or ratiometric response to palladium with high sensitivity and selectivity. Additionally, the novel NIR probe can monitor palladium species in live HeLa ce...

2-Dodecylthiomethylpyridine (DTP) was newly synthesized to study its extraction properties for precious metals. DTP was a selective extractant for palladium(II) and gold(III) over base metals. The loading test for palladium(II) showed that one palladium ion reacted with one molecule of DTP. The extraction rate of palladium with DTP was measured using a Lewis-type transfer cell at 303 K. The ext...

We report the environmental benign route in the synthesis of palladium nanoparticles using the aqueous leaf broth of Acalypha indica L. In this protocol, the biomolecules present in the leaf broth, reduced palladium ions into palladium nanoparticles and these biomolecules also acted as capping and stabilizing agents. The colour change in the reaction medium from pale yellow to dark brown during...

Highlights are presented of recent results obtained on deuterium and hydrogen loading of palladium both in electrolytes and in the gas phase. Reproducible tritium generation has been found on palladium cathodes with deuterium loadings approaching one deuterium atom per palladium atom. Tritium generation has been observed on four out of four such highly loaded cathodes. No tritium has been obser...

This compound is a liquid crystal polymer composed of palladium and lipoic acid. It has been reported to show DNA electronic reducing activity by cyclic voltammetry (1). A charge transfer from membrane phospholipid to DNA is the presumptive mechanism whereby certain tumors, protozoa, and yeasts, are inhibited by this complex. The subcellular site of destruction has been shown to be the membrane...

The goal of this work is the separation and recovery of platinum and palladium from spent catalyst. The recovery consisted of separating the maximum amount of platinum and palladium from catalysts and changing them into usable forms. The petroleum and petrochemical units use Pt and Pd catalyst for reactions such as reforming and hydrogenation. Because these materials contain valuable metals...

TÜBİTAK Marmara Research Center, Chemistry Institute, 41470 Gebze, Kocaeli, Turkey Email: [email protected] Activated carbon-supported palladium catalysts are liable to progressive deactivation even in the absence of any gaseous contaminants during the oxidation of hydrogen under ambient conditions. The high value of palladium coupled with environmental considerations means that n...
