Machine‐Learning Enhanced Parametric Reynolds‐Averaged Navier‐Stokes Equations at the Full‐ and Reduced‐Order Levels

open access: yesInternational Journal for Numerical Methods in Engineering, Volume 127, Issue 17, 15 September 2026.
ABSTRACT In this contribution, we focus on the Reynolds‐averaged Navier‐Stokes (RANS) models and their exploitation to build reliable reduced‐order models to further accelerate predictions for real‐time applications and many‐query scenarios. Specifically, we investigate how machine learning can be employed to enhance the predictive capabilities of the ...

Challenges and Opportunities for Layered Double Perovskite Solar Cells

open access: yesSolar RRL, Volume 10, Issue 17, 15 September 2026.
Layered lead‐free double perovskites suffer from intrinsic and extrinsic limitations that hinder high photovoltaic performance. This review identifies key challenges, including unfavorable band structures, strong self‐trapping, defect‐induced recombination, processing‐induced inhomogeneity, and device‐level mismatches.

A Fast and Parallelized Procedure for Checking Molecular Dynamics 3D Structure

open access: yesJournal of Computational Chemistry, Volume 47, Issue 23, September 5, 2026.
Common structural issues such as atomic overlaps, abnormal bond lengths, and ring‐bond intersections can be rapidly detected in the pairlist‐enabled and parallelized “checkstructure” command from CPPTRAJ, for example, the ~256 k atom 5a9z system can be checked in less than 2 s using 16 threads.

Interaction‐Driven Assembly Pathways in Heterogeneous Active Microrobotic Systems

open access: yesAdvanced Functional Materials, Volume 36, Issue 73, 10 September 2026.
Peanut‐ and cube‐shaped light‐powered microrobots exhibit distinct magnetic and photocatalytic responses that determine their heterogeneous self‐assembly. In the dark, magnetic dipole interactions drive colloidal copolymerization with cubes acting as nucleation centers, whereas under light irradiation, phoretic interactions compete with magnetic ...

Thermoresponsive Soft and Self‐Anchoring Cuff Electrode for Chronic Peripheral Interfaces

open access: yesAdvanced Functional Materials, Volume 36, Issue 75, 17 September 2026.
A novel thermoresponsive, soft and self‐anchoring (TSSA) cuff electrode utilizing shape memory polymers achieves autonomous, sutureless peripheral nerve fixation. Driven by thermally induced pre‐strain and tissue adhesion, the device self‐closes and softens at body temperature, successfully minimizing mechanical mismatch. This adaptive platform ensures
