Ruthenium and Osmium as Hydrogenation Catalysts

Platinum Metals Review, 1964
It has been shown in a previous article in this journal that the hitherto little studied metals ruthenium and osmium possess catalytic activities which are comparable with those of the other noble Group VIII metals for the hydrogenation of the n-butenes, buta-1,3-diene and acetylene.

An Integrated Artificial Intelligence Framework for Nanomedicine Engineering

Advanced Science, EarlyView.
This review outlines a closed‐loop AI ecosystem for nanomedicine engineering. By synergizing multimodal data harmonization, objective‐driven AI architectures, and automated high‐throughput validation, this “Design‐Make‐Test‐Analyze” (DMTA) workflow transforms traditional heuristic formulation into a predictive, self‐optimizing paradigm, accelerating ...

Promoted Ru/PrOx Catalysts for Mild Ammonia Synthesis

Ammonia synthesis is one of the most important chemical reactions. Due to thermodynamic restrictions and the reaction requirements of the current commercial iron catalysts, it is also one of the worst reactions for carbon dioxide emissions and energy ...

Molecular Electrocatalysis Coupled With a Palladium Membrane Reactor Affords Selective Nitrogen Reduction

Advanced Science, EarlyView.
A palladium membrane reactor delivers active hydrogen to homogeneous nickel terpyridine catalysts, which then selectively hydrogenate dinitrogen to ammonia. ABSTRACT Ammonia production is a cornerstone of modern industry and society, yet the conventional Haber–Bosch process accounts for nearly 2% of the global CO2 emissions. A promising and potentially

Highly efficient catalysis of dimethyl terephthalate hydrogenation by Ru catalyst loaded on rod-shaped CeO2

Results in Engineering
Hydrogenation of aromatic rings is a promising method for synthesizing fine chemicals and for hydrogen storage. Ruthenium-based catalysts are the most common alternatives for expensive palladium catalysts. However, developing efficient Ru-based catalysts

Porphyrin‐Based Porous Materials for Antibacterial Applications

Advanced Science, EarlyView.
Porphyrin‐based porous materials have excellent photophysical properties and tunable structures for high‐efficiency antibacterial therapy. This review comprehensively discusses the structural design strategies and synthetic pathways of the four main types of porphyrin‐based porous materials, summarizes their cross‐domain antimicrobial applications, and
