Palladium(II)‐Catalyzed CH Activation/CC Cross‐Coupling Reactions: Versatility and Practicality

open access: yesAngewandte Chemie - International Edition, 2009
In the past decade, palladium-catalyzed C-H activation/C-C bond-forming reactions have emerged as promising new catalytic transformations; however, development in this field is still at an early stage compared to the state of the art in cross-coupling ...

Palladium-Catalyzed Ligand-Directed C−H Functionalization Reactions

open access: yesChemical Reviews, 2010
1.1 Introduction to Pd-catalyzed directed C–H functionalization The development of methods for the direct conversion of carbon–hydrogen bonds into carbon-oxygen, carbon-halogen, carbon-nitrogen, carbon-sulfur, and carbon-carbon bonds remains a critical ...

How palladium inhibits CO poisoning during electrocatalytic formic acid oxidation and carbon dioxide reduction

open access: yesNature Communications, 2022
Development of reversible and stable catalysts for the electrochemical reduction of CO 2 is of great interest. Here, we elucidate the atomistic details of how a palladium electrocatalyst inhibits CO poisoning during both formic acid oxidation to carbon ...

Investigation by STEM-EELS of helium density in nanobubbles formed in aged palladium tritides [PDF]

open access: yesJ. Alloys Compd., 878 (2021) 160267, 2021
3He nanobubbles created by radioactive decay of tritium in palladium tritide are investigated after several years of aging. Scanning Transmission Electron Microscopy Electron Energy-Loss Spectroscopy (STEM-EELS) has been used to measure helium density from the helium K-edge around 23 eV. Helium densities were found between 20 and 140 (+/-30) He/nm3 and

Resistivity testing of palladium dilution limits in CoPd alloys for hydrogen storage [PDF]

open access: yesMaterials 15, 111 (2022), 2022
Palladium satisfies most of the requirements for an effective hydrogen storage material with two major drawbacks: it has a relatively low gravimetric hydrogen density and is prohibitively expensive for large-scale applications. Pd-based alloys should be considered as possible alternatives to a pure Pd.

$L$-hole Pockets of the Palladium Fermi Surface Revealed by Positron Annihilation Spectroscopy [PDF]

open access: yes, 2021
Using the combined Density Functional and Dynamical Mean Field theory we study relativistic corrections to the Fermi surface of palladium. We find indeed that relativistic corrections create a small hole pockets at the $L$-symmetry points. Furthermore we show that the computed two dimensional Angular Correlation of Electron Positron Annihilation ...

Emergence of magnetism in bulk amorphous palladium [PDF]

open access: yesPhys. Rev. B 100, 024422 (2019), 2019
Magnetism in palladium has been the subject of much work and speculation. Bulk crystalline palladium is paramagnetic with a high magnetic susceptibility. Palladium under pressure and palladium nanoclusters have generated interest to scrutinize its magnetic properties.
