4. One-point Gleason parts and point derivations in uniform algebras

Author

Ghosh, Swarup N. and Izzo, Alexander J.

Subjects
Mathematics - Functional Analysis, Mathematics - Complex Variables, 46J10
Abstract

It is shown that a uniform algebra can have a nonzero bounded point derivation while having no nontrivial Gleason parts. Conversely, a uniform algebra can have a nontrivial Gleason part while having no nonzero, even possibly unbounded, point derivations.

34. A Hull with No Nontrivial Gleason Parts

Author

Subjects
Mathematics - Complex Variables, 32E20, 46J10
Abstract

The existence of a nontrivial polynomially convex hull with every point a one-point Gleason part and with no nonzero bounded point derivations is established. This strengthens the \hbox{celebrated} result of Stolzenberg that there exists a nontrivial polynomially convex hull that contains no analytic discs. A doubly generated counterexample to the peak point conjecture is also presented.

38. Stabilizing a Ru single atom catalyst through electronic metal–support interaction with a NiCo2O4 support for overall water splitting and urea electrolysis.

Abstract

Single atom catalysts have manifested themselves as a new frontier in heterogeneous catalysis owing to their maximum atom utilization efficiency. However, their tendency to aggregate leads to poor stability, which limits their application. Herein, we overcome this challenge by stabilising a noble metal single atom catalyst through anchoring it on a metal oxide support, where a strong electronic metal–support interaction prevents their aggregation. Specifically, we have synthesized Ru single atoms anchored on the NiCo2O4 support by using an ultra-low amount of Ru. XAS and HAADF-STEM analysis confirm the presence of isolated Ru single atoms on the support. These isolated Ru atoms have a high density of unoccupied orbitals, which is favourable for electrocatalytic activity. The synthesized Ru single atom catalyst (Ru-SAC) on NiCo2O4 shows superior activity for overall water splitting with a cell potential of 1.57 V, showing excellent stability of 60 h. The synthesized Ru-SAC NiCo2O4 is also active in urea electrolysis and exhibits a cell potential of 1.41 V to generate a current density of 10 mA cm−2 . Density functional calculations reveal that supported single Ru atoms optimized the binding energies of the intermediate of both the HER and OER. [ABSTRACT FROM AUTHOR]
