Heterogeneous electro-Fenton removal of polyacrylamide in aqueous solution over CoFe2O4 catalyst

Water Science and Technology
Polyacrylamide (PAM) in environmental water has become a major problem in water pollution management due to its high molecular mass, high viscosity and non-absorption by soil.

Alleviation of Aging‐Related Hallmarks in a Mouse Model of Progeria via a Nanoparticle‐Based Artificial Transcription Factor

Advanced Functional Materials, EarlyView.
Oct4‐nanoscript, a biomimetic nanoparticle‐based artificial transcription factor, precisely regulates cellular rejuvenation by activating Oct4 target genes, restoring epigenetic marks, and reducing DNA damage. In a progeria model, it effectively rescued aging‐associated pathologies and extended lifespan.

Synthesis of polyacrylamide in aqueous solution: solubility

Orbital: The Electronic Journal of Chemistry, 2012
The synthesis of aqueous polyacrylamide solution was evaluated for its solubility in water. The reactions were performed using the acrylamide monomer, solvent and initiator (K2S2O8), with the system under magnetic stirring and heating (60°C) for 4 hours.

A single-source molten salt synthesis of uniform octahedral Na2Ti3O7 particels composed of nanorods [PDF]

arXiv, 2018
Na2Ti3O7, as one of the most potential anode electrode materials, is expected to play an important role in various fields. In this work, we synthesized uniform hollow octahedral Na2Ti3O7 particles through directly sintering a kind of precursors obtained by (NH4)2TiF6 and NH4OH in the presence of sodium-containing cationic polyacrylamide.

Bacteria‐Derived Extracellular Vesicle as A “Trojan Horse” for Selective M1 Macrophage‐Targeting in A Multi‐Cellular Entanglement Environment

Advanced Functional Materials, EarlyView.
The temporary transition of macrophages from a pro‐inflammatory phenotype of macrophages (M1) to an anti‐inflammatory phenotype of macrophages (M2) is crucial for tissue repair and regeneration processes. Bacterial outer membrane vesicles (OMVs) are utilized as a “trojan horse” for specific M1 macrophage‐targeting and anti‐inflammatory drug delivery ...

A Visible Light‐Responsive Hydrogel to Study the Effect of Dynamic Tissue Stiffness on Cellular Mechanosensing

Advanced Functional Materials, EarlyView.
A visible light‐responsive polyacrylamide‐azobenzene hydrogel enables safe, reversible stiffness control for studying cell mechanobiology without harmful UV exposure. This approach reveals stem cells respond rapidly to mechanical changes, showing altered shape and protein distribution within one hour.

Scaling Analysis of Surfactant Templated Polyacrylamide Gel Surfaces [PDF]

Journal of Colloid and Interface Science 258, 186-197, 2003., 2001
Surfaces of surfactant-templated polyacrylamide hydrogels were imaged by atomic force microscopy (AFM), and the surface morphology was studied by numerical scaling analysis. The templated gels were formed by polymerizing acrylamide plus a cross-linker in the presence of surfactants, which were then removed by soaking in distilled water.

Double Cross‐Linked Hydrogel for Intra‐articular Injection as Modality for Macrophages Metabolic Reprogramming and Therapy of Rheumatoid Arthritis

Advanced Functional Materials, EarlyView.
A hydrogel for intra‐articular injection for the treatment of rheumatoid arthritis (RA) is formulated and comprehensively studied. After administration, the hydrogel induces a metabolic reprogramming of immunometabolism of macrophages to trigger fatty acid oxidation subsequently inducing polarization of anti‐inflammatory M2 macrophages. This results in
