Designing Atomically Precise and Robust COF Hybrids for Efficient Photocatalytic CO₂ Reduction

open access: yesSmall, EarlyView.
The rational design of a novel covalent organic framework (COF)‐based hybrid CO2 photocatalyst allows for the atomistic level‐resolution of immobilized Rhenium(I) centers in the porous structure. The ReI‐decorated dibenzochrysene COF shows outstanding photocatalytic performance with a CO production rate of 1.16 mmol g−1 h−1 and long‐term photostability

Boosting the Stability of FAPbI3 Perovskite Nanocrystal Near‐Infrared Light‐Emitting Diodes with Aromatic Ligands and Organic Host Dispersion

open access: yesSmall, EarlyView.
Aromatic ligand exchange with 2,2‐diphenylethylamine (DPEA) and dispersion in π‐conjugated organic hosts enhance the photostability and device lifetime of near‐infrared FAPbI3 perovskite nanocrystal LEDs. This strategy suppresses energy transfer, improves quantum efficiency, and extends operational stability, offering a robust platform for stable ...

Senescent Endothelial Cells in Cerebral Microcirculation Are Key Drivers of Age‐Related Blood–Brain Barrier Disruption, Microvascular Rarefaction, and Neurovascular Coupling Impairment in Mice

open access: yesAging Cell, EarlyView.
Senolytic therapy restores neurovascular function, blood–brain barrier integrity, and cognitive performance in aged mice by targeting endothelial senescence. Findings highlight that brain microvascular endothelial cells are highly vulnerable to aging‐induced senescence, and early intervention in middle age may be the most effective strategy to prevent ...

Early identification of the use of potent benzylbenzimidazoles (nitazenes) through wastewater analysis: Two years of data from 22 countries

open access: yesAddiction, EarlyView.
Abstract Background and Aims The use of new synthetic opioids, such as the highly potent 2‐benzylbenzimidazoles (i.e. nitazene) drugs, is a global health concern because of their increased risk of fatal overdose. In the early 2020s, nitazene analogues were linked to significant numbers of overdoses in the United States.

Trends in novel opioid use and detections in exposures and police drug seizures in New South Wales

open access: yesDrug and Alcohol Review, EarlyView.
Abstract Introduction Novel opioids, including non‐medical and non‐opium‐based opioids such as fentanyl analogues and nitazenes, pose a significant risk of harm due to their high potency. There is little published data on novel opioid detections and harms in Australia, yet they are implicated in multiple deaths.
