Syntheses are reported for catalysts derived from platinum and palladium nanoparticles supported on a mesoporous phenol formaldehyde polymer modified by an ionic liquid. These catalysts are used for the hydrogenation of unsaturated compounds, specifically, acyclic and cyclic isoprenoids: isoprene, 2,5 – dimethyl–2,4–hexadiene, limonene, α –terpinene, γ –terpinene, as well as phenylacetylene, transstilbene, and 1,4–diphenyl–1,3–butadiene. High activity was found for these catalysts in hydrogenation reactions. The palladium catalysts were more active than their platinum analogs. The products of complete hydrogenation predominate in the hydrogenation of isoprenoids on the palladium catalysts, while monoene products predominate in the reactions on platinum catalysts.

We derive the stress tensor of a flexible polymer solution within the Gaussian-chain self-consistent field theory (SCFT) without invoking the ground-state dominance (GSD) approximation. Starting from a covariant formulation of the single-chain partition function in a background metric, we obtain the symmetric stress tensor expressed through the full Edwards propagators. The result contains the local ...

The electric double layer (EDL) at a single-crystal metal surface is controlled not only by the electrolyte composition and the electrode potential, but also by the atomic structure of the surface itself. This makes the Ag(hkl)/NaF interface a stringent test for continuum theories of the EDL. In the third part of our series, we examine ...

A self-consistent statistical-mechanical theory of the Hall effect in electrolyte solutions is developed by extending the self-consistent Debye–Hückel–Onsager (SCDHO) framework to crossed electric and magnetic fields. The theory incorporates non-local ionic charge distributions via Slater-type form factors, regularizing the Coulomb interaction at short range, and accounts for dielectric friction through ion-specific coefficients, employing experimental values ...

The rational design of coinage metal nanocarriers requires a mechanistic understanding of metal-drug binding and predictive descriptors that translate molecular interactions into design rules. Using DFT (B3LYP-D3BJ/def2-TZVP, SMD water), we systematically investigated the binding of 5-fluorouracil (5-FU) and levodopa (l-DOPA) to neutral and cationic homo- and heteronuclear dimers of Au, Ag, and Cu (Au2, Ag2, ...

We present two models with explicit long-range electrostatics in the form of Coulomb interactions. Both models include point charges depending on their local atomic environments, and the second model also conserves a total charge of an atomic system. We combine the proposed long-range models with the local moment tensor potential (MTP) and demonstrate that they ...

Wide-bandgap (WBG) perovskites used in monolithic tandem solar cells are limited by nonradiative recombination losses and operational instability originating from defect formation during crystallization and their subsequent evolution under illumination. Here, we show that defect formation can be regulated at the precursor stage by coordination chemistry, instead of relying only on post-crystallization passivation. A fluorinated ...

Density functional theory (DFT) is the workhorse of modern reactions and materials modeling. While the exact functional remains unknown, many approximations to it have been constructed either by hand-crafting functional forms to satisfy exact constraints or by machine learning. In this work, we show how both of these approaches can be fused to build both ...

In this work we characterize mixed Mo-W acidic deposition solutions with Mo content ranging from 0 to 100 mol.% by Raman and UV–Vis spectroscopy. The obtained distribution diagram of mixed isopolyanions allows one to explain the observed change in film deposition rate with increase in Mo content. It was found that the initial decrease in ...

Metal-mediated self-assembly of isocyanides and methyl 4-aminopyrimidine-5-carboxylate leads to luminescent PdII and PtII complexes featuring C,N-cyclometalated acyclic diaminocarbene (ADC) ligands. The solid-state luminescent properties of these diaminocarbene derivatives are attributed to their triplet-state metal/metal-to-ligand charge-transfer (3MMLCT) nature, which is driven by attractive intermolecular M···M interactions further reinforced by the intramolecular π–π interactions even in the ...

Aryl chlorides, due to their affordability and accessibility, are preferred reagents in Pd-catalyzed arylation reactions. However, the reactivity of aryl chlorides is often lower than that of aryl bromides and iodides due to the significantly higher barriers of the oxidative addition stage.

Herein we demonstrate that it may not be true, mainly because sophisticated organic substrates and modern reagents are often as expensive as ...
