Excessive consumption of fossil fuels has led to an un-precedented increase of carbon dioxide (CO2) emission and triggered a series of environment issues and energy crisis [1].Converting CO2 into hydrocarbon fuels has been regarded as an effective approach,which can solve the environmental problems and fulfill the high requirements of energy con-sumption [2].Methanol is an important chemical and trans-portation fuel,which also plays a vital role in the synthesis of other important chemicals such as methyl tert-butyl ether and dimethyl ether [3].Hydrogenation of CO2 to methanol,which directly utilizes CO2 as the raw material,has not only environmental benefits but considerable economic ad-vantages.

We use the technique of Ruan(1999)and Li and Ruan(2001)to construct the virtual neighborhoods and show that the Gromov-Witten invariants can be defined as integrals over the top strata of the virtual neighborhoods.We prove that the invariants defined in t
We prove that if a compact Riemannian 4-manifold with positive sectional curvature satisfies a strengthened Kato type inequality,then it is definite.We also discuss some new insights for compact Riemannian 4-manifolds with positive sectional curvature.
Associated with a Clifford system on R2l,a Spin(m+1)action is induced on R2l.An isoparametric hypersurface N in S2l-1 of OT-FKM(Ozeki,Takeuchi,Ferus,Karcher and Münzner)type is invariant under this action,and so is the Cartan-Münzner polynomial F(x).This
In this paper we study the Lp dual Minkowski problem for the case p＜0＜q.We prove for any positive smooth function f on S1,there exists an F:R+→ R-,such that if F(q)＜p＜0 or 0＜q＜-F(-p)then there is a smooth and strictly convex body solving the planar Lp dua
The notion of the Ricci curvature is defined for sprays on a manifold.With a volume form on a manifold,every spray can be deformed to a projective spray.The Ricci curvature of a projective spray is called the projective Ricci curvature.In this paper,we in
In this paper,we consider the problem of the nonnegative scalar curvature(NNSC)-cobordism of Bartnik data(Σn-11,γ1,Hi)and(Σn-12,γ2,H2).We prove that given two metrics γ1 and γ2 on Sn-1(3≤n≤7)with H1 fixed,then(Sn-1,γ1,H1)and(Sn-1,γ2,H2)admit no NNSC-cobor
The Christoffel problem is equivalent to the existence of convex solutions to the Laplace equation on the unit sphere Sn.Necessary and sufficient conditions have been found by Firey(1967)and Berg(1969),by using the Green function of the Laplacian on the s
Motivated by our previous work on Hodge-index type theorems,we give a form of mixed Hodge-Riemann bilinear relation by using the notion of m-positivity,whose proof is an adaptation of the works of Timorin(1998)and Dinh and Nguyên(2006).This mixed Hodge-Ri
Motivated by the study of coupled K?hler-Einstein metrics by Hultgren and Witt Nystr?m(2018)and coupled K(a)hler-Ricci solitons by Hultgren(2017),we study in this paper coupled Sasaki-Einstein metrics and coupled Sasaki-Ricci solitons.We first show an iso
This study proposes two different methods of photocatalytic-controlled and visible light-induced selective oxidation of pyr-idiniums with air as the terminal oxidant.The key to these transformations is to choose the appropriate light source and photocatal
