Regulation of Excitonic Behavior in Defective Acetylenic Polymers Enables Mechanism Switching in O2 Activation for Enhanced Water Decontamination

open access: yesAdvanced Science, EarlyView.
A molecular defect‐mediated charge accumulation strategy is developed to regulate the exciton behavior for selective molecular oxygen (O2)activation in poly(1,3,5‐triethynylbenzene) (PTEB). Artificial internal electric field (IEF) constructed in defective PTEB provides internal driving force to steer the directed migration of charge carriers, thereby ...

In Situ Utilization of Co‐Existing Metal Ions to Fabricate Single‐Atom Catalyst for Boosting Fenton‐Like Activity

open access: yesAdvanced Science, EarlyView.
A metal‐free TQBQ‐COF with pre‐designed anchoring sites captures coexisting Cu²⁺ from wastewater to form a single‐atom catalyst within 1 min. This in‐situ fabrication boosts visible‐light photo‐Fenton activity, enabling efficient removal of organics pollutants via 1O2 and holes.

Interior Decorative VOCs Elevate T Cell‐Mediated Obstructive Lung Disease Risks via Osteogenesis‐Driven Lymphoid‐Biased Hematopoiesis

open access: yesAdvanced Science, EarlyView.
This study utilizes a whole‐body inhalation model to reveal that interior decorative VOCs exposure persistently elevates alveolar T cells. This increase is attributed to lymphoid‐biased hematopoiesis in the bone marrow, which is further driven by IL‐6/IL‐17A‐mediated osteogenic differentiation.

ZIF‐67‐Confined Pd Single‐Atom Catalysts Implanted Into Polydopamine‐Modified Bamboo Microchannels for Robust Continuous‐Flow Hydrogenation

open access: yesAdvanced Science, EarlyView.
The report presents a facile room‐temperature method to stabilize Pd single‐atom catalysts within ZIF‐67 crystals during their formation. Despite an ultralow Pd loading (0.0014 wt%), the catalytic microreactor, featuring atomically dispersed Pd‐N4 sites in ZIF‐67, demonstrates superior robustness and maximized Pd utilization, significantly ...

The Pivotal Role of GR‐CAR Pathway in Fetal Programming of Hepatic Cytochrome P450 3A Alteration in Adulthood

open access: yesAdvanced Science, EarlyView.
Prenatal dexamethasone exposure (PDE) persistently upregulates hepatic CYP3A1/CYP2B1 in offspring via glucocorticoid receptor (GR) activation. In vivo and in vitro studies show GR promotes P300/CBP binding to the constitutive androstane receptor (CAR) promoter, sustaining histone acetylation (H3K9/K27ac) and enhancing CYP expression. The GR–CAR pathway
