Field Report from Collaborative Research Center 1625: Heterogeneous Research Data Management Using Ontology Representations

Advanced Engineering Materials, EarlyView.
A unified research data management framework for heterogeneous materials data is presented. The system integrates multimodal datasets using ontologies and knowledge graphs, enabling interoperability and FAIR (findable, accessible, interoperable, reusable) data principles. By linking data across scales and workflows, it supports reproducible, Artifitial

Structural and Phase States of Rhodium Doped Silicon Monocrystals

East European Journal of Physics
In this paper, the structural and phase states of silicon (Si) monocrystals doped with rhodium (Rh) atoms were investigated. For the study, n-type silicon samples doped with rhodium, grown by the Chokralsky method, were selected.

Atomic-level insights in optimizing reaction paths for hydroformylation reaction over Rh/CoO single-atom catalyst

Nature Communications, 2016
Despite the advantages of using heterogeneous catalysts, most successful rhodium hydrogenations are carried out with homogeneous catalysts. Here the authors report a supported single atom rhodium catalyst providing high activities and selectivities for ...

Crystal structures of fac-trichloridotris(trimethylphosphane-κP)rhodium(III) monohydrate and fac-trichloridotris(trimethylphosphane-κP)rhodium(III) methanol hemisolvate: rhodium structures that are isotypic with their iridium analogs

Acta Crystallographica Section E: Crystallographic Communications, 2015
The crystal structures of two solvates of fac-trichloridotris(trimethylphosphane-κP)rhodium(III) are reported, i.e. one with water in the crystal lattice, fac-[RhCl3(Me3P)3]·H2O, and one with methanol in the crystal lattice, fac-[RhCl3(Me3P)3]·0.5CH3OH ...

Self‐Cleaning Sensor Surfaces for Long‐Term Environmental Monitoring

Advanced Engineering Materials, EarlyView.
Long‐term use of unattended outdoor sensors without soiling or biofouling is achieved through generation of a micro‐ and nanorough cuvette surface by combing hydrophobic nanoparticles with fluorinated polymers, crosslinked and surface‐attached through CHic chemistry. The coating demonstrates self‐cleaning behavior and prolonged outdoor stability, which

Laser‐Induced Graphene from Waste Almond Shells

Advanced Functional Materials, EarlyView.
Almond shells, an abundant agricultural by‐product, are repurposed to create a fully bioderived almond shell/chitosan composite (ASC) degradable in soil. ASC is converted into laser‐induced graphene (LIG) by laser scribing and proposed as a substrate for transient electronics.

A computational study of supported rhodium catalysts

, 2010
In this work, density functional theory (DFT) was used to obtain microscopic structures of heterogeneous catalysts based on rhodium supported on a metal oxide (-Al2O3). Two different methodologies were used.

Rhodium-Catalyzed Regioselective Double Annulation of Enaminones with Propargyl Alcohols: Rapid Access to Arylnapthalene Lignan Derivatives

, 2021
We present here a rhodium-catalyzed oxidative three-point double annulation of enaminones with propargylic alcohols via a C–H and a C–N bond activation to access arylnaphthalene-based lignan derivatives. The key step in the reaction is the regioselective
