ChemCatChem, Volume 15, Issue 1, January 9, 2023., 2023 The mediator portfolio of electrosynthesis holds untapped potential for photocatalytic applications. A systematic approach toward harnessing electrochemical mediators for photocatalysis is presented using the phenanthroimidazole framework, a known electrocatalytic system, as a test case.

Existence of positive radial solution for Neumann problem on the Heisenberg group
Boundary Value Problems, 2020 The existence of at least one positive radial solution of the Neumann problem −ΔHnu+R(ξ)u=a(|ξ|Hn)|u|p−2u−b(|ξ|Hn)|u|q−2u,\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage ...

Inducing Propeller Chirality in Triaryl Boranes with Chiral Amines
Chemistry – A European Journal, Volume 28, Issue 70, December 15, 2022., 2022 A three‐point interaction between a chiral amine and a triarylborane is shown to suffice to induce a preferential propeller handedness to the borane. Rotation of aryl blades can be avoided by incorporation of naphthyl instead of phenyl and a bulky amine component.

Dorronsoro's theorem in Heisenberg groups [PDF]
Bulletin of the London Mathematical Society, 2020 A theorem of Dorronsoro from the 1980s quantifies the fact that real-valued Sobolev functions on Euclidean spaces can be approximated by affine functions almost everywhere, and at all sufficiently small scales. We prove a variant of Dorronsoro's theorem in Heisenberg groups: functions in horizontal Sobolev spaces can be approximated by affine functions

Hölder Regularity of Quasiminimizers to Generalized Orlicz Functional on the Heisenberg Group
Journal of Function Spaces, 2020 In this paper, we apply De Giorgi-Moser iteration to establish the Hölder regularity of quasiminimizers to generalized Orlicz functional on the Heisenberg group by using the Riesz potential, maximal function, Calderón-Zygmund decomposition, and covering ...

Chirality Induced Spin Selectivity – the Photoelectron View
Israel Journal of Chemistry, Volume 62, Issue 11-12, December 2022., 2022 Abstract In this short overview we discuss the manifestation of the chirality‐induced spin selectivity (CISS) effect in photoelectron spectroscopy experiments with direct spin analysis. Various systems, from the initially investigated monolayers of molecular biosystems and organic hepta‐helicene to recent chirally grown solid oxide films, are evaluated.

Isodiametric sets in the Heisenberg group [PDF]
Revista Matemática Iberoamericana, 2012 In the sub-Riemannian Heisenberg group equipped with its Carnot–Carathéodory metric and with a Haar measure, we consider isodiametric sets , i.e., sets maximizing measure among all sets with a given diameter. In particular, given an isodiametric set, and up to negligible sets, we prove that its boundary is given by

Journal of Computational Chemistry, Volume 44, Issue 3, Page 367-380, January 30, 2023., 2023 Exchange interactions in polynuclear Fe (III) compounds are derived from ab initio calculations based on a single spin‐flip (1SF) approach. Abstract Low‐energy spectra of single‐molecule magnets (SMMs) are often described by Heisenberg Hamiltonians.
