Rh-based heterogeneous catalysts generally have limited selectivity relative to their homogeneous counterparts in hydroformylation reactions despite of the convenience of catalyst separation in heterogeneous catalysis. Here, we develop CoO-supported Rh single-atom catalysts (Rh/CoO) with remarkable activity and selectivity towards propene hydroformylation. By increasing Rh mass loading, isolate...

In this theoretical research, the mechanism of the C2H + C2H2 reaction is studied by high-level quantum-chemical methods and kinetics of the reaction is investigated by statistical rate theories. High-level electronic structure calculation methods including M06-2X, CCSD(T), CBS-Q and G4 methods are employed to explore the doublet potential energy surface of the reaction and compute the molecula...

a 7 year-old male presented with recurrent fever, cough and respiratory distress for over last 2 years. based on extremely high eosinophil count, high immunoglobulin e, increase in eosinophilic precursors in bone marrow, and positive antigen test for wuchereria bancrofti, a diagnosis of tropical pulmonary eosinophilia with eosinophilic leukemoid reaction was made. complete recovery was achieved...

Systems chemistry aims to emulate the functional behavior observed in living systems by constructing chemical reaction networks (CRNs) with well-defined dynamic properties. Future expansion of the complexity of these systems would require external control to tune behavior and temporal organization of such CRNs. In this work, we design and implement a photolabile probe, which upon irradiation st...

Biological rhythms are regulated by homeostatic mechanisms that assure that physiological clocks function reliably independent of temperature changes in the environment. Temperature compensation, the independence of the oscillatory period on temperature, is known to play a central role in many biological rhythms, but it is rather rare in chemical oscillators. We study the influence of temperatu...
