Beyond Presumptions: Toward Mechanistic Clarity in Metal‐Free Carbon Catalysts for Electrochemical H2O2 Production via Data Science

Advanced Materials, EarlyView.
Metal‐free carbon catalysts enable the sustainable synthesis of hydrogen peroxide via two‐electron oxygen reduction; however, active site complexity continues to hinder reliable interpretation. This review critiques correlation‐based approaches and highlights the importance of orthogonal experimental designs, standardized catalyst passports ...

Directional Flow of Confined Polaritons in CrSBr

Advanced Materials, EarlyView.
CrSBr, a layered magnetic semiconductor, naturally channels self‐hybridized excitonpolaritons into highly directional flow. Its intrinsic optical anisotropy, high refractive index, and strong lightmatter coupling enable long‐range guided modes along the a‐axis, with propagation lengths set by their excitonphoton admixture.

A construction of real weight functions for certain orthogonal polynomials in two variables

Journal of Mathematical Analysis and Applications, 2006
Real orthogonalizing weight functions for the orthogonal polynomials satisfying to the following four types of partial differential equations \[ \begin{gathered} x^2u_{xx}+2xyu_{xy}+(y^2-y)u_{yy}+g(x-1)u_x+g(y-\gamma)u_y=\lambda y\\ (x^2+y)u_{xx}+2xyu_{xy}+y^2u_{yy}+gxu_x+g(y-1)u_y=\lambda y\\ (x^2-x)u_{xx}+2xyu_{xy}+y^2u_{yy}+(dx+e)u_x+(dy+h)u_y ...

3D Anodic Alumina Nanoarchitectures: A Decade of Progress from Foundational Science to Functional Metamaterials

Advanced Materials, EarlyView.
Ordered three‐dimensional anodic aluminum oxide (3D‐AAO) nanoarchitectures with longitudinal and transverse pores enable architecture‐driven metamaterials. The review maps fabrication advances, including hybrid pulse anodization, and shows how 3D‐AAO templates tailor properties across magnetism, energy, catalysis, and sensing.

Tough, Ductile, and Strong Hard‐Soft Cementitious Composite Enabled by Multi‐Material Additive Manufacturing

Advanced Materials, EarlyView.
Drawing inspiration from the layered hard‐soft architecture found in sea sponges, this work establishes a new framework for architected cementitious composites (ACC) through multi‐material additive manufacturing (MMAM) process. The integration of mortar and elastomer phases into layered architectures enables synergistic toughening mechanisms, including

Orthogonal polynomials and Gaussian quadrature rules related to oscillatory weight functions

Journal of Computational and Applied Mathematics, 2005
In the last years, the study of orthogonal polynomials and related topics like quadrature rules and Padé approximants with respect to a complex weight function, has become an interesting research topic where the first author of the paper under review, and his co-workers, have greatly contributed. In this paper, the case of the complex weight function \(

One‐Dimensional Materials Supported in Two‐Dimensional Van der Waals Metal–Organic Frameworks with Optical Anisotropy Switching via Twist‐Engineering

Advanced Materials, EarlyView.
We introduce a molecular strategy to assemble one‐dimensional (1D) materials into two‐dimensional (2D) van der Waals metal–organic frameworks (MOFs). Crystals of [FeX(pzX)(bpy)] (X = Cl, F) form anisotropic 2D layers that can be mechanically exfoliated into thin sheets.
