Conductive Organic Cages Enable Efficient Capture and Transistor Detection of ppq-Level Perfluorooctanoic Acid

This study presents a conductive organic cage (ReTTFcage) that simultaneously achieves record-breaking adsorption capacity and kinetics for removing perfluorooctanoic acid (PFOA) from water while functioning as a miniaturized field-effect transistor sensor capable of detecting PFOA at the ultra-trace ppq level.

Soil type and moisture dynamics govern the physicochemical aging of superabsorbent polyacrylic acid hydrogels in soil

This study demonstrates that the loss of swelling functionality in polyacrylic acid superabsorbent hydrogels within soil is primarily driven by rapid physicochemical aging and condensation with soil minerals under moisture fluctuations, rather than microbial degradation, with the rate and extent of these transformations being governed by soil type and moisture dynamics.

Structural, magnetic, optical, and microwave absorption properties of Fe0.67Co0.33/CoCexFe2-xO4 (х=0.0, 0.1, 0.2, 0.3) composites

Hydrothermally synthesized Fe0.67Co0.33/CoCexFe2-xO4 composites exhibit a cerium-dependent evolution in structural, magnetic, and optical properties, where increasing Ce3+ content reduces crystallite and grain sizes, lowers coercivity and saturation magnetization, narrows the band gap to enhance methylene blue degradation, and modifies microwave absorption characteristics.
