Grenzflächen‐Photoelektrochemie in der Organischen Synthese

Angewandte Chemie, Volume 137, Issue 42, October 13, 2025.
Heterogene Photoelektroden sind für die Aktivierung von H2O und CO2 weit verbreitet, während homogene Photoelektrochemie mit molekularen Katalysatoren die Aktivierung komplexer Moleküle in der Synthese dominiert. Dennoch bietet Grenzflächen‐Photoelektrochemie (iPEC) ein großes Potenzial für die Synthese, einschließlich Kosteneffizienz ...

Australian continental‐scale heavy mineral patterns track climate, weathering and erosion

Sedimentology, Volume 72, Issue 5, Page 1430-1452, August 2025.
ABSTRACT The heavy mineral cargo of sediment is influenced by a complex and variable overprint of climate and environmental processes acting on weathered crystalline basement sources. Here, a continental‐scale heavy mineral compositional dataset of 1315 surface sediment samples, analysed via automated mineralogy, from across Australia is utilized to ...

Further results for the Dunkl Transform and the generalized Ces\`aro operator [PDF]

, 2012
In this paper, we consider Dunkl theory on R^d associated to a finite reflection group. This theory generalizes classical Fourier anal- ysis. First, we give for 1 < p

A Fractional Laplacian and Its Extension Problem

Mathematical Methods in the Applied Sciences, Volume 48, Issue 9, Page 9840-9852, June 2025.
ABSTRACT In this paper, we establish four equivalent characterizations of the fractional Laplacian operator (−‖x‖Δk)σ$$ {\left(-\left\Vert x\right\Vert {\Delta}_k\right)}^{\sigma } $$ with 0<σ<1$$ 0<\sigma <1 $$, in some class of functions on ℝd$$ {\mathbb{R}}^d $$.

Besov-Type Spaces on R^d and Integrability for the Dunkl Transform

Symmetry, Integrability and Geometry: Methods and Applications, 2009
In this paper, we show the inclusion and the density of the Schwartz space in Besov-Dunkl spaces and we prove an interpolation formula for these spaces by the real method. We give another characterization for these spaces by convolution.

Corrosion of zirconium‐based refractories in glass‐contact areas: Mechanisms and challenges

International Journal of Applied Ceramic Technology, Volume 22, Issue 3, May/June 2025.
Abstract Zirconium‐based refractories are essential materials in the glass industry due to their outstanding properties including high refractoriness, good thermal shock resistance, and high corrosion resistance with respect to contact with the molten glass, making them suitable for use in critical parts of glass melting furnaces, such as the bottom ...

Spectrum of Functions for the Dunkl Transform on R^d [PDF]

, 2007
Mathematics Subject Classification: 42B10In this paper, we establish real Paley-Wiener theorems for the Dunkl transform on R^d. More precisely, we characterize the functions in the Schwartz space S(R^d) and in L^2k(R^d) whose Dunkl transform has bounded,

Plate Interface Shear Zone in the Sanbagawa Metamorphic Belt, Constrained by RSCM Thermometry, U–Pb Zircon Dating and Phase Equilibria Modelling in the Sarutagawa Region, Central Shikoku, Japan

Journal of Metamorphic Geology, Volume 43, Issue 3, Page 257-285, April 2025.
ABSTRACT Exhumed high‐P/low‐T complexes are of paramount importance to directly access rocks that experienced subduction zone processes. However, the original tectono‐metamorphic fabrics are often partially obliterated by exhumation and later deformation, hindering our understanding of the processes occurring at depth.

Sonine Transform Associated to the Dunkl Kernel on the Real Line

Symmetry, Integrability and Geometry: Methods and Applications, 2008
We consider the Dunkl intertwining operator V_α and its dual ^tV_α, we define and study the Dunkl Sonine operator and its dual on R. Next, we introduce complex powers of the Dunkl Laplacian Δ_α and establish inversion formulas for the Dunkl Sonine ...

Riesz transform and Riesz potentials for Dunkl transform

Journal of Computational and Applied Mathematics, 2007
Analogous of Riesz potentials and Riesz transforms are defined and studied for the Dunkl transform associated with a family of weighted functions that are invariant under a reflection group. The $L^p$ boundedness of these operators is established in certain cases.
