Ruthenium catalysts for the synthesis of quinolines and enol esters
… was to investigate the scope and limitations of ruthenium Schiff base catalysts for two types of reactions. In a modification of the Friedlander reaction, 2-aminobenzylalcohol is oxidatively cyclized with ketones or aldehydes, affording quinolines. The key step in this method is a hydrogen …

Deuterium Enrichment and the Kinetic Isotope Effect during Ruthenium Catalyzed Fischer-Tropsch Synthesis
… of this synthesis was carried out with a ruthenium catalyst at controlled temperatures and pressures. Two types of experiments were performed: H2/D2 switching and competitive methods. The products showed that the hydrocarbon production rate was slightly increased when syngas was switched …

Studies toward Augmented Carbene/Alkyne Cascade Reactions and Ruthenium Catalysts for Propargylic Substition
… The second part discusses the synthesis of a ruthenium catalyst and its application for propargylic substitution. The third part describes an improvement of a Robinson annulation for the synthesis of aplykurodinone 1. Alkyne/cascade reactions are highly effective processes in organic …

Mechanophore activation at heterointerface and surface crowdedness as a determining factor
… a thermally and mechanically triggerable ruthenium catalyst system for material remodeling application were also discussed."

Functional electrospun fibers for responsive coatings and sacrificial templates
… system with Grubbs’ 2nd generation ruthenium catalyst and cyclic poly(phthalaldehyde) is developed, where concurrent polymerization of bulk polymer and decomposition of sacrificial material to produce vasculature is demonstrated.

Characterizing the fate and transport of chemicals of emerging concern (CECs) from swine manure during waste to energy processes
… 300°C/60minutes for HTL and 500°C/60minutes with Ruthenium catalyst (Ru) for CHG. The Xenoscreen YES assay was used to investigate the effects hydrothermal processes on eliminating the estrogenic activity of LPAM. Increasing reaction temperature in hydrothermal processes generally reduced the …

Testing the suitability of local seaweeds and formulated feed as a food source for abalone (Haliotis midae Linnaeus) in an Integrated Land-based Aquaculture System
… combination. The core functioning component is a catalyst containing MEA, where when pure platinum is used, carbon monoxide is the thermodynamic sink and poisons by preventing further reactions at catalytic sites decreasing the life span of the catalyst if the CO is not removed. Research has shown …

Engineering novel tandem reactions using organometallic catalysts and (metallo)enzymes
… and biocatalysis. Over the years, catalysts of these three classes have enabled ground-breaking chemical transformations. The application of chemocatalysis to the manufacturing of chemicals is widespread, and biocatalysis is increasingly being used industrially. To streamline …

Chemical Modification of Cellulose Esters for Oral Drug Delivery
… hydroboration agent and sodium acetate as base catalyst in oxidation successfully avoided cleavage of ester linkages by borane reduction and base catalyzed hydrolysis. With the impetus of modular and efficient synthesis, we introduced olefin cross-metathesis (CM) in polysaccharide …

Non-Thermal Contribution to Ruthenium Photothermal Catalyst in Carbon Dioxide Methanation
… thermometer capable of accurately measuring catalyst surface temperature independent of emissivity. By fitting the continuous NIR emission spectrum (950–1600 nm), this technique achieves ±1 °C accuracy above 200 °C, enabling reliable distinction between thermal and non-thermal effects. Using …
