The Importance of Metal‐Organic Framework Linker Atoms for CO2 Reduction: A DFT Study
Advanced Science, EarlyView.Using DFT, we examine the role of linker atoms in CO2 reduction on copper‐based metal organic frameworks (Cu MOFs). Our calculations reveal that linker atoms may serve as both CO2 and H‐shuttling sites and suggest linker electrostatics as a descriptor for linker activity. ABSTRACT Although the metal within the secondary building unit of a metal‐organic

N,N′-Bis(2-furylmethylene)-1,1′-binaphthyl-2,2′-diamine
Acta Crystallographica Section E, 2008 In the title compound, C30H20N2O2, the orientation of the furyl group may induce a variety of coordination modes with this ligand. The dihedral angle between the two naphthyl rings is 79.25 (7)°.

Weak automorphisms of dihedral groups [PDF]
Algebra universalis, 2010 Let \(G\) be a group; a bijective map \(\tau\colon G\to G\) is called a weak automorphism of \(G\) if for every \(n\in\mathbb N\), every \(g_1,g_2,\dots,g_n\in G\) and every \(\alpha_1,\alpha_2,\dots,\alpha_n\in\mathbb Z\) there are \(\beta_1,\beta_2,\dots,\beta_n\in\mathbb Z\) such that \[ \tau(g_1^{\alpha_1}\cdot g_2^{\alpha_2}\cdots g_n^{\alpha_n})=\

Advanced Science, EarlyView.Rational engineering of terminal substituents in symmetric azobenzene‐based molecules enables precise control over conformationally coupled charge‐transfer processes. This design yields tunable nonvolatile resistive memory behaviors, ranging from write‐once‐read‐many‐times (WORM) to rewritable switching.

Advanced Science, EarlyView.Here, we designed the Me‐FBSe molecule and prepared a two‐dimensional molecular crystal via liquid‐liquid interface assembly. The crystal preserves the high photoluminescence quantum while simultaneously ensuring the high‐density surface exposure of active sites.

Distance-regular Cayley graphs on dihedral groups [PDF]
, 2007 The main result of this article is a classification of distance-regular Cayley graphs on dihedral groups. There exist four obvious families of such graphs, which are called trivial.

Γ-supermagic labeling of products of two cycles with dihedral groups
Indonesian Journal of CombinatoricsA Γ-supermagic labeling of a graph G=(V,E) is a bijection from E to a group Γ of order |E| such that for every vertex x∈V a product of labels of all edges incident with x is equal to the same element µ∈Γ.

On schurity of dihedral groups
Journal of AlgebraA finite group $G$ is called a Schur group if every $S$-ring over $G$ is schurian, i.e. associated in a natural way with a subgroup of $Sym(G)$ that contains all right translations. One of the crucial questions in the $S$-ring theory is the question on schurity of nonabelian groups, in particular, on existence of an infinite family of nonabelian Schur ...
