Nonreversibility of subsemigroups of semi-simple Lie groups
Semigroup Forum, 1992 A subsemigroup \(S\) of a Lie group \(G\) is called reversible if \(aS\cap bS\neq\emptyset\neq Sa\cap Sb\) for any two \(a,b\in S\). Equivalently one has the condition that \(SS^{-1}\) and \(S^{-1}S\) are subgroups of \(G\). The author shows that for a semisimple Lie group \(G\) with finite center a semigroup \(S\) with non-empty interior can only have

Compactification of semi-simple Lie groups
, 2019 We discuss the `hd-compactification' of a semi-simple Lie group to a manifold with corners; it is the real analog of the wonderful compactification of deConcini and Procesi. There is a 1-1 correspondence between the boundary faces of the compactification and conjugacy classes of parabolic subgroups with the boundary face fibering over two copies of the

Advanced Functional Materials, EarlyView.A single‐step, low‐temperature co‐pyrolysis process removes encapsulated seed metal NPs (10–50 nm) from CNTs, redistributing them as surface‐anchored metal and metal–nitride NCs (1–1.5 nm). Herein, Ni3N NCs achieve an ultra‐low onset overpotential for CO2 reduction to CO with >98% Faradaic efficiency across 100–700 mA cm−2.

Flag-transitive non-symmetric 2-designs with λ prime and exceptional groups of Lie type
AIMS MathematicsThis paper contributes to the classification of flag-transitive 2-$ (v, k, \lambda) $ designs. Let $ \mathcal{D} $ be a non-trivial and non-symmetric $ 2 $-$ (v, k, \lambda) $ design with $ \lambda $ prime and $ G $ be a flag-transitive point-primitive ...

Decoding the Structure of Benzodithiophene Polymers for High‐Efficiency Organic Solar Cells
Advanced Functional Materials, EarlyView.This study reveals a unique solid mesophase in top‐performing benzodithiophene‐based polymers for solar cells, comprising stacked solid‐like and liquid‐like layers. Combining nanoscale fibrillar domains with amorphous regions, it introduces a new structural paradigm.

Compact Simple Lie Groups and Their C-, S-, and E-Transforms
Symmetry, Integrability and Geometry: Methods and Applications, 2005 New continuous group transforms, together with their discretization over a lattice of any density and admissible symmetry, are defined for a general compact simple Lie groups of rank 2 ≤ n < ∞. Rank 1 transforms are known.

Simple Finite Jordan Pseudoalgebras
Symmetry, Integrability and Geometry: Methods and Applications, 2009 We consider the structure of Jordan H-pseudoalgebras which are linearly finitely generated over a Hopf algebra H. There are two cases under consideration: H = U(h) and H = U(h) # C[Γ], where h is a finite-dimensional Lie algebra over C, Γ is an arbitrary

Advanced Functional Materials, EarlyView.Hollow poly(heptazine imide) spheres are prepared through a novel approach that integrates hard templating with ionothermal synthesis. This method enables precise control over surface area, pore volume, hydrophilicity, light absorption, band position, and metal composition. These tunable properties facilitate the customized design of semiconductors for
