A Neutral “Masked” Diborene and Its Reactivity Toward Metal‐Free Pyridine Homocoupling
Angewandte Chemie, EarlyView.An unprecedented neutral “masked” diborene, formed via intramolecular arene dearomatization of an N‐heterocyclic imine‐supported free diborene, can be photochemically released to regenerate the highly reactive triplet diborene intermediate. Computational analysis elucidates the bonding situation of the hitherto elusive free diborene species, and the ...

Group Codes Over Dihedral Group Algebras 𝔽q[D16] and 𝔽q[Z2 × D8]
Journal of MathematicsLet Fq denote a finite field of characteristic p, where q=pk for some prime p and integer k. Let Dn represent a dihedral group of order n. In this paper, group codes in the dihedral group algebras FqD16 and FqZ2×D8 are proposed.

Bilangan Kromatik Grap Commuting dan Non Commuting Grup Dihedral
Cauchy: Jurnal Matematika Murni dan Aplikasi, 2015 Commuting graph is a graph that has a set of points X and two different vertices to be connected directly if each commutative in G. Let G non abelian group and Z(G) is a center of G.

Public Key Protocols over Twisted Dihedral Group Rings [PDF]
, 2019 Key management is a central problem in information security. The development of quantum computation could make the protocols we currently use unsecure. Because of that, new structures and hard problems are being proposed. In this work, we give a proposal

Advanced Science, EarlyView.Photocatalytic treatment of glyphosate herbicide in agricultural wastewater is achieved through the cooperative effect of the local polarization field and dipole field mediated by lattice‐distorted carbon nitride. Glyphosate is completely degraded via selective C─P bond cleavage with a CO evolution rate of 1166 µmol g−1 h−1.

A Negatively Curved Pyrene‐Fused Azaacene
Angewandte Chemie, EarlyView.A pyrene‐fused azaacene derivative is reported in which steric overcrowding caused by eight phenyl substituents induces bending of the aromatic framework rather than twisting. ABSTRACT Non‐planar aromatic hydrocarbons display distorted π‐frameworks that give rise to unique optoelectronic properties.

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

Angewandte Chemie, EarlyView.Covalently linked carbazole dimers exhibit intense excimer‐based circularly polarized luminescence (CPL). A simple propylene‐tethered dimer achieves glum ≈ 0.01 in the violet region—among the highest for small organic emitters without heavy atoms. Conformational mapping reveals CPL is governed by thermodynamic/kinetic control of emissive conformers ...

Some properties of Square element graphs over semigroups
AKCE International Journal of Graphs and Combinatorics, 2020 The Square element graph over a semigroup is a simple undirected graph whose vertex set consists precisely of all the non-zero elements of , and two vertices are adjacent if and only if either or belongs to the set , where 1 is the identity of the ...

On Order Prime Divisor Graphs of Finite Groups
Discussiones Mathematicae - General Algebra and Applications, 2021 The order prime divisor graph 𝒫𝒟(G) of a finite group G is a simple graph whose vertex set is G and two vertices a, b ∈ G are adjacent if and only if either ab = e or o(ab) is some prime number, where e is the identity element of the group G and o(x ...
