Article Abstract
Removing per- and polyfluoroalkyl substances (PFAS) in water resources at trace concentrations (ng/L) is scientifically challenging. Herein, a cation-π system was constructed comprising a Fe(II)/Fe(III) coordinated graphene-like structure encapsulating Fe° catalyst (Fe(II)/Fe(III)-GL@Fe), realizing rapid PFAS mineralization in municipal wastewater and raw drinking water under ambient atmospheric conditions without external energy input. The strong electric field was generated from DOC-PFAS-HO-O synergistic coordination at Fe species area and GL area on Fe(II)/Fe(III)-GL@Fe via surface charge rearrangement by Fe-π interaction, triggering surface electrochemical-like redox reactions: sequential adsorbed C-F bond oxidation, adjacent bond homolysis, and O reduction until complete PFAS mineralization. Our findings highlight the potential of electric energy generation from multicomponent coordination on Fe-modified GL-based catalyst in developing cost-effective novel technologies for PFAS micropollutant purification in real water.

Carbon dots (CDs) represent a new class of nontoxic and sustainable nanomaterials with increasing applications. Among them, bright and large Stokes-shift CDs are highly desirable for display and imaging, yet the emission mechanisms remain unclear. We obtained structural signatures for the recently engineered green and red CDs by ground-state femtosecond stimulated Raman spectroscopy (FSRS), then synthesized orange CDs with similar size but much higher nitrogen dopants than red CDs.

In recent years, light-controlled ion transport systems have attracted widespread attention, however, the use of photoresponsive materials suffers from rapid carrier recombination, thermal field limitations, and narrow spectral response, which significantly restricts their performance enhancement in osmotic energy conversion. This study innovatively couples "blue energy" (osmotic energy) with "green energy" (solar energy), assembling graphene oxide/molybdenum disulfide/sulfonated cellulose nanocrystal (GO/ MoS/CNC) ion-channel membranes. Under solar irradiation, the energy level difference between MoS and GO effectively suppresses the recombination of photogenerated carriers, generating more active electrons and significantly enhancing the carrier density, thereby improving the current flux and ion selectivity.

Advanced biosensing technologies, such as Förster resonance energy transfer (FRET) and bioluminescence resonance energy transfer (BRET), have enabled real-time, high-resolution tracking of Rho GTPase activity, surpassing traditional methods like pull-down assays. However, current biosensors mainly detect the GTP-bound active state through effector interactions, without directly measuring Rho GTPase expression or identifying related biomarkers of abnormal activation. Small Rho GTPases are essential molecular switches that regulate key cellular processes such as cytoskeletal organization, cell movement, polarity, vesicle trafficking, and the cell cycle.

Owing to its wide bandgap, LaAlO has garnered extensive attention in the field of high-temperature negative temperature coefficient (NTC) thermistors. However, its poor thermal stability and excessively high B value limit the working temperature range. In this work, introducing O 2p and Ni 3d hybrid energy levels into the bandgap is proposed via Ni doping and inducing stacking faults in the crystal structure to narrow the bandgap and enhance aging performance.

Achieving superior energy storage performance in dielectric materials under low electric fields remains a challenge. Most recent advancements require high fields that limit device applicability. Developing dielectric capacitors with high recoverable energy density (W), efficiency (η), and energy-storage coefficient (W/E) at low/moderate fields is critical for safer, compact, and durable electronics.
