MIM‐Diode‐Like Rectification in Lateral 1T/1H/1T‐MoS2 Homojunctions via Interfacial Dipole Engineering

open access: yesAdvanced Electronic Materials, Volume 12, Issue 3, 4 February 2026.
The metallic 1T and semiconducting 1H phases of MoS2 enable phase‐engineered 1T/1H/1T homojunctions that exhibit MIM‐diode‐like rectification without dissimilar electrodes. Asymmetric 1T/1H interfaces induce interface dipoles and a built‐in potential drop across the 1H barrier, creating a trapezoidal tunnel barrier at zero bias and yielding diode‐like ...

Low Parsons–Zobel slope of metal–solution interfaces: A theoretical comparison of three causes

open access: yesAIChE Journal, Volume 72, Issue 2, February 2026.
Abstract Rational design of electrochemical energy conversion and storage devices hinges on a fundamental understanding of the electrical double layer (EDL) at the electrode–electrolyte interface. The classical Gouy–Chapman–Stern model of EDL predicts a unity Parsons–Zobel (PZ) slope, which is derived from the relation between inverse measured ...

Screw‐Dislocation‐Engineered Quantum Dot: Geometry‐Tunable Nonlinear Optics, Orbital Qubit Addressability, and Torsion Metrology

open access: yesAnnalen der Physik, Volume 538, Issue 2, February 2026.
A uniform torsion field—representing a controlled density of parallel screw dislocations—confines a single electron into a geometry‐defined quantum dot. In a perpendicular magnetic field, an Aharonov–Bohm flux breaks the m↔−m$m \leftrightarrow -m$ symmetry and yields a flux‐ and torsion‐tunable angular pseudospin (m=±1)$(m = \pm 1)$ with asymmetric ...

Sharp commutator estimates of all order for Coulomb and Riesz modulated energies

open access: yesCommunications on Pure and Applied Mathematics, Volume 79, Issue 2, Page 207-292, February 2026.
Abstract We prove functional inequalities in any dimension controlling the iterated derivatives along a transport of the Coulomb or super‐Coulomb Riesz modulated energy in terms of the modulated energy itself. This modulated energy was introduced by the second author and collaborators in the study of mean‐field limits and statistical mechanics of ...

An Ecological Definition and Objective Threshold for Differentiating Small Fragments

open access: yesEcology and Evolution, Volume 16, Issue 2, February 2026.
Many ecological phenomena vary with fragment size. To quantify the impacts of small fragments on ecological pattern and process, one must differentiate them, but there is no agreed way to achieve this. We present an objective definition and method to identify a threshold size for small fragments that requires minimal data and can be readily calculated ...
