Deciphering the Origin of Higher Shell Coordination on Single Iron Catalysts for Resilient Modulating Persulfate Oxidation Into Singlet Oxygen Pathway

open access: yesAdvanced Functional Materials, Volume 35, Issue 12, March 18, 2025.
This study reveals that higher shell S coordination can effectively modulate the spin state of FeN4 site via long‐range electronic interactions, giving rise to the oriented generation of singlet oxygen from peroxymonosulfate activation. Abstract Precise manipulation of coordination structure of single‐atom sites and establishment of schematic ...

Time optimal problems on Lie groups and applications to quantum control

open access: yesCommunications in Analysis and Mechanics
In this paper we introduce a natural compactification of a left (right) invariant affine control system on a semi-simple Lie group $ G $ in which the control functions belong to the Lie algebra of a compact Lie subgroup $ K $ of $ G $ and we investigate ...

On the subgroup structure of exceptional groups of Lie type

open access: yes, 1998
We study finite subgroups of exceptional groups of Lie type, in particular maximal subgroups. Reduction theorems allow us to concentrate on almost simple subgroups, the main case being those with socle X(q) of Lie type in the natural characteristic.

Achieving Large and Anisotropic Spin‐Mediated Thermal Transport in Textured Quantum Magnets

open access: yesAdvanced Functional Materials, Volume 35, Issue 12, March 18, 2025.
An advanced solvent‐cast cold pressing method is developed to synthesize highly textured quantum magnets. By aligning spin chains in Ca2CuO3 perpendicular to the pressing direction, a spin‐mediated thermal conductivity of 10 ± 1 W m⁻¹ K⁻¹ is achieved, the highest reported for polycrystalline quantum materials.

An introduction to spherical orbit spaces

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2002
Consider a compact, connected Lie group G acting isometrically on a sphere Sn of radius 1. Two-dimensional quotient spaces of the type Sn/G have been investigated extensively.

Cohomology of algebraic groups, Lie algebras, and finite groups of Lie type

open access: yes, 2022
Let G be a reductive algebraic group over a field of prime characteristic. One can associate to G (or subgroups thereof) its Lie algebra, its Frobenius kernels, and the finite Chevalley group of points over a finite field. The representation theories of these structures are highly interconnected.

Biologically‐Inspired Melt Electrowriting for the Generation of Highly Biomimetic Functional Myocardium

open access: yesAdvanced Functional Materials, EarlyView.
In this work, melt electrowriting is used to fabricate a 3D printed scaffold design that generates engineered cardiac tissues with in‐plane contraction, mimicking natural myocardium. It is shown that these tissues display advanced maturation and functionality.
