Two-component reaction of 2-aminobenzophenones with acetylenic esters in the presence of γ-Al2O3 and Cu/ZnO as suitable heterogeneous catalysts has been studied. Nano γ-Al2O3 and Cu/ZnO showed high activities when used as surface catalysts for the synthesis of quinoline derivatives. After completion of the reaction, the catalyst was ...

In this paper, we study the diffusion approximation for singularly perturbed stochastic reaction-diffusion equation with a fast oscillating term. The asymptotic limit original system is obtained, where an extra Gaussian term appears. Such explicitly given in terms of solution Poisson Hilbert space. Moreover, also obtain rate convergence, and convergence shown not to depend on regularity coeffic...

A green, efficient, chemoselective, facile and clean procedure is described and discussed for the synthesis of α, α'-bis (substituted-benzylidene) cycloalkanones in solvent-free conditions. The condensation reaction was carried out through the reaction of aromatic aldehydes with cycloalkanones in the presence of Fe3O4@WO3 (Fe3O4@WO3</s...

Abstract In this paper, we shall study the formation of stationary patterns for a reaction-diffusion system in which FitzHugh-Nagumo (FHN) kinetics, its excitable regime, is coupled to linear cross-diffusion terms. (Gambino et al. Excitable Fitzhugh-Nagumo model with cross-diffusion: long-range activation instabilities, 2023), proved that supports emergence cross-Turing patterns, i.e., close-to...

observed, and D ∆ is the (time-dependent) diffusion coefficient measured at this diffusion time. Short-time-scale measurements of hyperpolarized He diffusion in the human lung typically use diffusion times between 1 and 2 ms. At this time scale, the He diffusion coefficient in normal lung airspaces is approximately 0.2 cm/s. Thus these measurements probe a length scale of approximately 350-500 ...
