Dual atomic catalysts （DAc）,particularly copper （cu2）-based nitrogen （N） doped graphene,show great potential to effectively convert cO2and nitrate （NO3-） into important industrial chemicals such as ethylene,glycol,acetamide,and urea through an efficient catalytical process that involves c–c and c–N ***,the origin of the coupling activity remained unclear,which substantially hinders the rational design of cu-based catalysts for the N-integrated cO2reduction reaction （cO2RR）.To address this challenge,this work performed advanced density functional theory calculations incorporating explicit solvation based on a cu2-based N-doped carbon (cu2N6c10) catalyst for *** calculations are aimed to gain insight into the reaction mechanisms for the synthesis of ethylene,acetamide,and urea via coupling in the interfacial reaction *** to the sluggishness of cO2,the formation of a solvation electric layer by anions （F-,cl-,Br-,and I-） and cations (Na+,Mg2+,K+,and ca2+) leads to electron transfer towards the cu *** process significantly accelerates the reduction of *** results reveal that*cO intermediates play a pivotal role in N-integrated ***,the cu2-based N-doped carbon catalyst examined in this study has demonstrated the most potential for c–N coupling to *** findings reveal that through the process of a condensation reaction between*cO and Nh2Oh for urea synthesis,*NO3-is reduced to*Nh3,and*cO2to*ccO at dual cu atom *** dual-site reduction facilitates the synthesis of acetamide through a nucleophilic reaction between Nh3and the ketene ***,we found that the I-and Mg2+ions,influenced by ph,were highly effective for acetamide and ammonia synthesis,except when F-and ca2+were ***,the mechanisms of c–N bond formation were investigated via ab-initio molecular dynamics simulations,and we found that adjusting the micro-environment can change the dominant side reaction,shift

In this paper we investigate the existence, uniqueness and regularity of the solution of semilinear parabolic equations with coefficients that are discontinuous across the interface, some prior estimates are obtained. A net shape of the finite elements around the singular points was designed in [7] to solve the linear elliptic problems, by means of that net, we prove that the approximate solution has the same convergence rate as that without singularity.

A mathematical model coupling the momentum, energy and species conservation equa-tions was proposed to calculate the macro--segregation of Fe--c alloy ingot during solid-ification. The corresponding simulation software which concurrently solves the macro-scopic mass, momentum, energy and species conservation equations has been developedby applying the SIMPLE algorithm.The thermo--solutal convection in a Nh_4 cl--h_2O ingot is verified and the result showsgood agreement with that reported. Then macro--segregation in a steel ingot is simu-lated by using the developed program. The steel ingot is in a rectangular mold with ariser. The fluid flow is mainly induced by the temperature field and the solid fraction.The macro--segregation pattern is mainly affected by the thermo--induced convectionin the mushy zone. The negative segregation forms along the walls of the casting.The positive segregation forms at the top center of the casting into the riser. Thespecies concentration reaches the peak in the center of the ingot where solidificationends lastly.

We present a rigorous theoretical model for the influence of the aperture in interferometric out-of-focus imaging. We investigate the role of this effect on the properties of speckle-like patterns generated by irregular, rough particles. Finally, we determine the conditions under which these patterns are no longer representative of particle size but of the aperture itself and the defocus parameter.

Tumor cells may escape immune surveillance mainlyby (1) down regulation of major histocompatibilitycomplex (Mhc) molecules or alteration of antigen-processing pathways; (2) low-level of cytokines in thevicinity of the tumor, which can’t activate immunosystemeffectively. Recent studies have shown that geneticallyengineered tumor cells expressing cytokines such as IL-2IFN-γ can induce greater cTL activity and activate NK,LAK and TIL. Besides IFN-γ can enhance the
