Synthesis and application of alginate@CuFe2O4 polymeric spheres in 17‐β‐estradiol adsorption processes in Amazonian rivers

open access: yesPolymer International, EarlyView.
Magnetic alginate beads, functionalized with copper ferrite, effectively remove 17‐β‐estradiol from Amazonian water, exhibiting optimized 238.65 μg g−1 capacity, fast 40 min kinetics, easy recovery, and successful remediation. Abstract The presence of endocrine‐disrupting compounds, such as 17‐β‐estradiol, in aquatic ecosystems poses a significant ...

Curcumin Alleviates the Osteogenesis Inhibition and the Aging Process in BMSCs Induced by Iron Overload Through Activating the NRF2/GPX4 Pathway

open access: yesPhytotherapy Research, EarlyView.
Under iron overload conditions, curcumin inhibits cellular senescence and promotes osteogenic differentiation by activating the NRF2/GPX4 signaling pathway in bone marrow mesenchymal stem cells (BMSCs), thereby preventing the onset of osteoporosis. ABSTRACT Dysregulated proliferation and differentiation of bone marrow mesenchymal stem cells (BMSCs ...

The scale matters: A review on stimuli‐responsive microrobots categorized by scale for biomedical applications

open access: yesResponsive Materials, EarlyView.
We systematically summarize how each scale dictates fundamental choices in design feature, manufacturing technology, driving mechanism, and control strategy, which are inherently governed by scale‐dominated physical principles. Furthermore, the application of scale‐determined operation modes of microrobots across different stages of medical ...

Ferromagnetic Cobalt Oxide With Structural Distortion and Oxidation State Changes for Hydrogen Sulfide Gas Detection

open access: yesSmall, EarlyView.
High H2S gas sensitivity was improved by electrochemically engineering Co3O4/CoO heterostructures with oxygen vacancies and aligning nanosized particles via magnetic‐field‐assisted deposition. This alignment enhanced gas diffusion and electron transport, reducing base resistance. The resulting sensor exhibited high selectivity and a strong response (Rg/
