Tri‐System Interlocking Top‐Encased Structures Enabled Highly Stable Tin‐Lead Perovskite Photodetection Arrays

open access: yesAdvanced Materials, EarlyView.
A unique tri‐system interlocking top‐encased structure is formed for tin‐lead perovskites by the introduction of novel CGA additive. The fabricated tin‐lead perovskite NIR photodetector shows an outstanding specific detectivity of 2 × 1013 Jones at 940 nm, and the integrated 64 × 64 array demonstrates clear and accurate imaging abilities.

Traceless Photopolymerization with Non‐Pulsed Red Light Enables 3D‐Printable Cell‐Laden Hydrogels

open access: yesAdvanced Materials, EarlyView.
The paper presents a red‐light‐induced polymerization process, initiated by the FDA‐approved dye methylene blue and the cytocompatible co‐initiator triethanolamine, for fabricating hydrogels. This photopolymerization process is oxygen‐tolerant, cytocompatible, and, most importantly, leaves no color traces, resulting in completely transparent scaffolds.

Stratified Petri Nets

open access: yes, 1997
We introduce a subclass of Valk's self-modifying nets. The considered nets appear as statified sums of ordinary nets and they arise as a counterpart to cascade products of automata via the duality between automata and nets based on regions in automata.

Artesunate Nanoplatform Targets the Serine–MAPK Axis in Cancer‐Associated Fibroblasts to Reverse Photothermal Resistance in Triple‐Negative Breast Cancer

open access: yesAdvanced Materials, EarlyView.
The artesunate nanoplatform selectively targets ECM CAF, functioning as a GTPase inhibitor through disruption of intracellular serine homeostasis. This metabolic intervention effectively suppresses MAPK cascade activity, which consequently inhibits PTT‐induced CAF to ECM CAF differentiation.
