Advanced Science, Volume 13, Issue 2, 9 January 2026.This study introduces an organic anion‐coordination for oxidation suppression (OCOS) strategy using alkali metal–organic anions (e.g., KEtO) to stabilize Sn2+ in lead‐free Sn‐based perovskites for PeLEDs. By coordinating with Sn2+ and inhibiting vacancies, OCOS enhances film quality, EQE (to 10.01% at 638 nm), and luminance (to 139.9 cd m−2 ...

Weight Systems from Feynman Diagrams
Journal of Knot Theory and Its Ramifications, 1998 We find that the overall UV divergences of a renormalizable field theory with trivalent vertices fulfil a four-term relation. They thus come close to establish a weight system. This provides a first explanation of the recent successful association of renormalization theory with knot theory.

Advanced Electronic Materials, Volume 12, Issue 2, 21 January 2026.We investigate the influence of hydrostatic pressure on the physical properties of monolayer FeCl2${\rm FeCl}_2$ for spintronics applications. A phase transition from a ferromagnetic half‐metal to a ferromagnetic semiconductor is unveiled at 4.6 GPa, accompanied by a transition from a non‐polar (1T) to a polar (1H) structure.

Aggregate, Volume 7, Issue 1, January 2026.The electronic spectra, luminescence decay measurements at room temperature and 77 K, and persistent luminescence have been recorded for pristine hexagonal and cubic CsCdCl3 and for this material doped with Mn2+ or Fe3+. First‐principles calculations have been performed in order to rationalize the results.

Annalen der Physik, Volume 538, Issue 1, January 2026.The BRST invariant Lagrangian of the gravitationally interacting U(1)$U(1)$ gauge theory, namely the Quantum GraviElectro Dynamics (QGED). The Yan–Mills theory with the Hilbert–Einstein gravitational Lagrangian, namely the Yang–Mills–Utiyama (YMU) theory, is defined and quantised using the standard procedure. The theory is perturbatively renormalisable,
