Synthesis of AgBiS2 and AgInS2 Based on Formation Energies in Sulfur‐Rich Reducing Flame
Advanced Functional Materials, Volume 36, Issue 61, 30 July 2026.High‐surface‐area AgInS2 and AgBiS2 nanoparticles were synthesized via enclosed flame spray pyrolysis by tuning flame conditions and formation energies to guide phase formation. Flame parameters were tuned to suppress oxides and enable pure sulfide phase growth.

Unraveling Upconversion Dynamics Through Laplace Transforms
Advanced Photonics Research, Volume 7, Issue 7, July 2026.The decay‐time curves of Yb3+ unravel the upconversion luminescence dynamics under different pulse widths and repetition rates of the excitation source. The proposed model is both simple and clearly explains the trend of the luminescence dynamics in upconverting nanomaterials, offering an invaluable tool for future discoveries.

Advanced Science, Volume 13, Issue 40, 17 July 2026.A quasi‐periodic Dart‐Kite (QDK) metastructure with a golden‐ratio‐constrained strong–weak bond network simultaneously enhances strength, toughness, and damage tolerance. Its distributed topology enables predictable, tailorable crack paths for precise fracture control and stable mechanics, demonstrating a high‐performance, controllable architecture ...

Acta Crystallographica Section B, Volume 82, Issue 3, Page 280-298, June 2026.In situ X‐ray diffraction is used for exploring Si crystallography and for studying phase‐transformation mechanisms in elemental Si and Na–Si systems. We present original results of hexagonal silicon, Si‐6H and a critical analysis of the past‐decade discoveries of silicon Si‐4H and Si24 using large‐volume high‐pressure techniques.Metastable allotropes ...

Littlewood, Paley and almost‐orthogonality: a theory well ahead of its time
Journal of the London Mathematical Society, Volume 113, Issue 5, May 2026.Abstract The classic paper by Littlewood and Paley [J. Lond. Math. Soc. (1), 6 (1931), 230–233] marked the birth of Littlewood–Paley theory. We discuss this paper and its impact from a historical perspective, include an outline of the results in the paper and their subsequent significance in relation to developments over the last century, and set them ...

Counting 5‐isogenies of elliptic curves over Q$\mathbb {Q}$
Journal of the London Mathematical Society, Volume 113, Issue 5, May 2026.Abstract We show that the number of 5‐isogenies of elliptic curves defined over Q$\mathbb {Q}$ with naive height bounded by H>0$H > 0$ is asymptotic to C5·H1/6(logH)2$C_5\cdot H^{1/6} (\log H)^2$ for some explicitly computable constant C5>0$C_5 > 0$. This settles the asymptotic count of rational points on the genus zero modular curves X0(m)$\mathcal {X}

A categorification of combinatorial Auslander–Reiten quivers
Journal of the London Mathematical Society, Volume 113, Issue 5, May 2026.Abstract We provide a categorification of Oh and Suh's combinatorial Auslander–Reiten quivers in the simply laced case. We work within the perfectly valued derived category pvd(ΠQ)$\mathrm{pvd}(\Pi _Q)$ of the 2‐dimensional Ginzburg dg algebra of a Dynkin quiver Q$Q$.
