A Projective Framework for Polyhedral Mesh Modelling

open access: yes, 2014
We present a novel framework for polyhedral mesh editing with face‐based projective maps that preserves planarity by definition. Such meshes are essential in the field of architectural design and rationalization.

Mechanistic Origin of Capacity Limitation in Sidorenkite‐Type Na3‐xFe(PO4)(CO3) Carbonophosphate Cathodes for Na‐Ion Batteries

open access: yesAdvanced Energy Materials, EarlyView.
The potential–capacity profile reveals a one‐electron limitation in sidorenkite Na3−xFe(PO4)(CO3). Structural analysis shows that Fe4+ formation induces lattice strain and suppresses electronic conductivity, blocking further Na extraction. These findings establish key design rules: preserve crystallinity, avoid Jahn–Teller–active d4 configurations, and

Mechanochemically Disordered Li2Ta2OCl10 Oxyhalide Unlocks Superionic Conductivity (>10 mS.cm−1)

open access: yesAdvanced Energy Materials, EarlyView.
This work presents a new crystalline oxyhalide, Li2Ta2OCl10, built from [Ta2OCl10]2− dimers. The disorder induced by ball‐milling drives the dramatic 5000‐fold increase in ionic conductivity to reach 11 mS.cm−1. The material shows promise as a solid electrolyte for batteries and opens new prospects for the discovery of new dimer‐based compounds ...

Dimensional Reduction of Transition Metal Dichalcogenides by Oxide Insertion: Quasi‐1D Oxychalcogenide Semiconductors

open access: yesAngewandte Chemie, EarlyView.
Molecular Scissors: Oxide insertion slices the layers of MQ2 transition metal dichalcogenides (TMDs) into one‐dimensional [M3Q6] nanoribbons, giving a new family of A2Hf3Q6O (A = K, Rb, Cs; Q = S, Se) oxychalcogenides. The heteroanion‐driven dimensional reduction yields direct‐gap semiconductors with optical absorption that is tunable across the ...

A subsequence characterization of sequences spanning isomorphically polyhedral Banach spaces [PDF]

open access: yes, 1998
Let (x_n) be a sequence in a Banach space X which does not converge in norm, and let E be an isomorphically precisely norming set for X such that (*) ∑_n |x*(x_{n+1} - x_n)| < ∞, ∀x* ∈ E.

Learning regime‐dependent governing equations: A symbolic decision tree approach

open access: yesAIChE Journal, EarlyView.
Abstract Many chemical engineering systems are governed by mechanisms that switch across operating regimes, making the data‐driven discovery of regime‐dependent governing equations essential for predictive modeling, optimization, and control. We propose symbolic decision trees for the data‐driven discovery of regime‐dependent governing equations.

Design of Giant Negative Thermal Expansion Based on a Fluorite Structure

open access: yesAngewandte Chemie, EarlyView.
Ba[B(CN)4]2 with a fluorite structure possessing a large average atomic volume was successfully synthesized for the first time. In situ powder X‐ray diffraction measurements revealed that Ba[B(CN)4]2 exhibits giant negative thermal expansion (NTE) behavior through non‐rigid unit modes with strongly negative Grüneisen parameters.

Cell Segmentation Beyond 2D—A Review of the State‐of‐the‐Art

open access: yesAdvanced Intelligent Discovery, EarlyView.
Cell segmentation underpins many biological image analysis tasks, yet most deep learning methods remain limited to 2D despite the inherently 3D nature of cellular processes. This review surveys segmentation approaches beyond 2D, comparing 2.5D and fully 3D methods, analyzing 31 models and 32 volumetric datasets, and introducing a unified reference ...
