Advanced Optical Materials, EarlyView.Compression to ≈2.0 GPa results in a non‐monotonic enhancement of the Pb‐I bond distortion, rarely observed in other 2D lead‐iodide hybrid perovskites. The octahedral distortion together with the rigidity of spacer cation are found to play a dominant role in determining the optoelectronic properties of DPDAPbI4 under high pressure.

Optical Properties of Thin Films of Tin Iodide Perovskite Nanostructures
Advanced Optical Materials, EarlyView.A comprehensive spectroscopic study of thin films of 3D CsSnI3 nanocrystals (NCs) that coexist with residual 2D Ruddlesden‐Popper nanosheets (NSs) has been performed. Polymer encapsulation enables solid‐state stabilization of the tin iodide perovskite nanostructures, while insight into the energetics and dynamics of the NC and NS excitons is provided ...

Advanced Optical Materials, EarlyView.A design principle is presented that maximizes absorption in ultrathin (tens of nanometers) Sn halide perovskite optoelectronic devices by aligning their intrinsic absorption wavelengths with Fabry–Pérot (FP) resonances. The ultrathin FASnI3 devices exhibit increases open‐circuit voltage, reduces dark current, and high photocurrent, yielding high ...

Formation Control of Multi‐Agent System with Local Interaction and Artificial Potential Field
Advanced Robotics Research, EarlyView.This article proposes a local interaction‐based formation control method for Multi‐Agent system, integrating consensus and leader‐follower strategies with a stress response mechanism—artificial potential field to reduce communication overhead and enable obstacle avoidance. Experimental results on triangular, square, and hexagonal formations confirm its

Advanced Sensor Research, EarlyView.SARS‐CoV‐2 particles in complex cell culture medium are detected using high‐frequency electrical measurements. This is made possible through the use of large arrays of independently addressable nanoelectrodes implemented using complementary metal oxide semiconductor (CMOS), semiconductor technology.

Advanced Theory and Simulations, EarlyView.This work presents a combined analytical–computational approach to quantify the influence of aspect ratio and anisotropic orientation on the percolation behavior of penetrable rectangles. The proposed model reliably predicts the geometric percolation threshold and electrical conductivity of 2D networks, with power‐law fits showing strong agreement with
