Swelling‐Programmed Topographical Guidance for Dynamic Spheroid Self‐Assembly via a Mechanochemical Hydrogel Niche

open access: yesAdvanced Functional Materials, EarlyView.
A swelling‐programmed micropatterned hydrogel guides adherent cells through a controlled transition from cell–matrix anchoring to cadherin‐mediated cell–cell compaction, enabling rapid assembly of high‐viability spheroids with defined size and morphology.

Queer Supercrystal Structure for Increasing Factorizations of Fixed-Point-Free Involution Words (Representation Theory and its Combinatorial Aspects)

open access: yesQueer Supercrystal Structure for Increasing Factorizations of Fixed-Point-Free Involution Words (Representation Theory and its Combinatorial Aspects)
本稿では, 一列型BCn型Koornwinder多項式P(1r)(xla, b, c, dlq, t)と一列型BCn型単項対称多項式m(1r)(x)の間の遷移行列Cを具体的に求め, 一列型BCn型Koornwinder多項式の一列型BCn-1型Koornwinder多項式による分規則を記述する. 証明のために一列型Koornwinder多項式の退化隣接関係(degeneration scheme)を導入する. 一列型Koornwinder多項式の退化隣接関係とは, 一列型Koornwinder多項式のパラメタa, b, c, dを次のように1つずつ特殊化した多項式を考えることである: (a, b, c, d)→ (a, -a, c, d)→(a, -a, c, -c)→ (√tc, -√tc, c,

Tissue‐Stimulator Platform for Electrically Stimulating Pancreatic β‐Cells for Long‐Term Functional Regulation

open access: yesAdvanced Functional Materials, EarlyView.
We present a tissue‐stimulator platform for seamless electrode integration with pancreatic tissue, applying uniform electrical stimulation through optimized design with biohybrid 3D printing. Advantageous effects of electrical stimulation on β‐cell function were observed, including enhanced calcium signaling, islet morphology, and maturation.

X‐Functionality–Driven Photocatalytic Hydrogen Evolution in 2D 4‐X‐PEA2SnI4 Perovskites

open access: yesAdvanced Functional Materials, EarlyView.
We report a water‐based synthesis of 2D 4‐X‐PEA2SnI4 perovskite microcrystals with prominent photocatalytic (PC) activity for H2 production. The synergy between organic functionalization and HI‐derived iodide scavenges holes suppress octahedral distortion, and favor electron accumulation, enabling a PC H2 evolution ∼20 µmol·g−1 and long‐term stability ...

Design Strategies and Emerging Applications of High‐Performance Flexible Piezoresistive Pressure Sensors

open access: yesAdvanced Functional Materials, EarlyView.
Flexible piezoresistive pressure sensors underpin wearable and soft electronics. This review links sensing physics, including contact resistance modulation, quantum tunneling and percolation, to unified materials/structure design. We highlight composite and graded architectures, interfacial/porous engineering, and microstructured 3D conductive networks
