TL;DR: In this paper, the direct ortho-trifluoromethylation of arenes, including heteroarenes, with TMSCF3 has been accomplished by a copper-II-promoted C-H activation reaction which completes within 30 minutes.
Abstract: The direct ortho-trifluoromethylation of arenes, including heteroarenes, with TMSCF3 has been accomplished by a copper (II)-promoted C-H activation reaction which completes within 30 minutes. Mechanistic investigations are consistent with the involvement of C-H activation, rather than a simple electrophilic aromatic substitution (SEAr), as the key step.

TL;DR: In this paper, the authors studied the dynamical behaviors of fractional-order Lotka-Volterra predator-prey system and its discretized counterpart and showed that the discretised system exhibits much richer dynamical behaviours than its corresponding fractional order form; in particular, many types of bifurcations (transcriti- cal, flip, Neimark-Sacker) and chaos are obtained.

TL;DR: It is confirmed both experimentally and theoretically that the unique N2-Zn-B2 configuration is crucial, in which Zn + can hold enough delocalized electrons to generate suitable binding strength for key reaction intermediates and promote the charge transfer between catalytic surface and ORR reactants.
Abstract: A zinc-based single-atom catalyst has been recently explored with distinguished stability, of which the fully occupied Zn2+ 3d10 electronic configuration is Fenton-reaction-inactive, but the catalytic activity is thus inferior. Herein, we report an approach to manipulate the s-band by constructing a B,N co-coordinated Zn-B/N-C catalyst. We confirm both experimentally and theoretically that the unique N2 -Zn-B2 configuration is crucial, in which Zn+ (3d10 4s1 ) can hold enough delocalized electrons to generate suitable binding strength for key reaction intermediates and promote the charge transfer between catalytic surface and ORR reactants. This exclusive effect is not found in the other transition-metal counterparts such as M-B/N-C (M=Mn, Fe, Co, Ni and Cu). Consequently, the as-obtained catalyst demonstrates impressive ORR activity, along with remarkable long-term stability in both alkaline and acid media. This work presents a new concept in the further design of electrocatalyst.

TL;DR: In this paper, NiO/CeO2 nanorods were successfully synthesized and examined as catalysts for the NH3-selective catalytic reduction (NH3-SCR) of nitric oxide (NO).
Abstract: CeO2 nanorods impregnated with 2.5 atom % of NiO (NiO/CeO2 nanorods) were successfully synthesized and examined as catalysts for the NH3-selective catalytic reduction (NH3-SCR) of nitric oxide (NO). The catalytic activity of NiO/CeO2 nanorods resulted in up to ∼90% NO conversion at 250 °C, which is superior to that of pure CeO2 nanorods or NiO nanoparticles. Subsequently, extensive studies of the NiO/CeO2-catalyzed reduction of NO were conducted using X-ray photoelectron spectroscopy, hydrogen temperature-programmed reduction, temperature-programmed desorption, and density functional theory periodic calculations. Compared to that of the pure CeO2 nanorods, the results demonstrated that the NiO/CeO2 nanorods resulted in (i) a higher concentration of Ce3+ chemical species, (ii) a larger amount of active Oα, (iii) lower temperature reducibility, (iv) a lower amount of energy required for oxygen vacancy distortion, and (v) a significant adsorption of and strong interaction between NO and NH3 molecules.
