Article Abstract
To solve the competitive energy decay pathways in photodynamic therapy (PDT) and photothermal therapy (PTT), herein, we proposed a fluorination strategy of AIE photosensitizers, which exhibited high ROS generation and heat release. Innovatively, femtosecond transient absorption spectroscopy has emerged to verify the extension of triplet excited state lifetime induced by C-F bonds. In order to improve its hydrophilicity and targeting ability, GSH-responsive nanogel HPCF was constructed, which presented controllable release of TPAF. experiments proved that HPCF-mediated PDT/PTT successfully downregulates heat shock proteins by reactive oxygen species and achieved synergetic phototherapy potential.

Polyesters, with their tunable chemical structures and environmental sustainability, have drawn growing attention as solid polymer electrolytes for next-generation solid-state lithium metal batteries (SSLMBs). Through a comprehensive experimental and theoretical study involving the systematic variation of carbon chain lengths in the flexible (diol) and coordinating (diacid) segments, along with selective fluorination at distinct positions along the polymer backbone, 18 types of polyester are fabricated and demonstrate that fluorination at the coordinating segment significantly enhances ionic conductivity by suppressing crystallinity. In contrast, fluorination at the flexible segment reduces ionic migration barriers by providing more homogeneous coordinating sites, thereby improving the lithium-ion transference number, despite increasing chain rigidity and a reduction in overall ionic conductivity.

Fluorine (F)-doped carbon materials (FCMs) were one-pot synthesized and applied as the catalysts for the cycloaddition of carbon dioxide (CO) towards the cyclic carbonate for the first time. In this process, F dopants and oxygen (O)-containing groups on the carbon surface played a key role in enhancing the activity. The FCM synthesized at 500 °C (FCM-500) with 5.

The construction of perfluoropolyether (PFPE) slippery liquid-infused porous surfaces (SLIPS) on gold coatings is one of the most effective strategies for bestowing anticoagulation and antimicrobial properties on the material. However, the poor chemical affinity between fluorinated porous precursors and gold substrates causes the agglomeration of nanostructures, resulting in uneven nanoporous morphology and accelerating lubricant leakage. Simultaneously, the weak interfacial adhesion between the nanostructures and the substrate may lead to the detachment of nanostructures under blood circulation.

The aluminum electrolysis industry generates massive greenhouse gas emissions dominated by CO and perfluorocarbons (PFCs, CF/CF), presenting dual challenges of climate impact and resource waste. Here, we report a robust nickel-based metal-organic framework (SIFSIX-3-Ni) featuring confined square channels (3.55 Å) that achieves the molecular-sieving separation of CO from CF/CF mixtures.

The rapid increase of electronic waste, particularly battery waste, presents significant environmental challenges such as pollutant emissions and resource depletion, emphasizing the need for effective valorization and reuse strategies. This study introduces a novel approach for repurposing end-of-life lithium iron phosphate (LFP) batteries as catalysts in the pyrolysis of walnut shells (WS). Characterization analyses revealed that LFP provides both Lewis and Brønsted acid sites, which alter the thermal decomposition pathway of WS.
