This work introduces the synthesis of a hydrophobic three-dimensional (3D) COP, TAPM-TFPDA, via an oligomer-mediated interfacial ripening method and its application in organic solvent nanofiltration (OSN). Utilizing an acetic acid-catalyzed system enables the room-temperature fabrication of 3D COP membranes. Characterization reveals that the TAPM-TFPDA membranes exhibit a narrow pore size distribution, exceptional solvent resistance, and high thermal stability. During interfacial ripening under the optimized conditions, the TAPM-TFPDA membrane achieved a 95.56% rejection of Evans blue and an ethanol permeance of 16.0 L·m^–2·h^–1·bar^–1. Notably, its permeance in polar solvents like acetonitrile significantly outperformed that in nonpolar solvents.

While polyurethanes can be synthesized entirely from renewable sources using aliphatic diisocyanates, they often exhibit inferior mechanical properties compared to their petroleum-based counterparts.

In vitro, PEEK@MSN exhibited exceptional osteogenic capabilities, significantly enhancing the differentiation of bone marrow stromal cells (BMSCs), the expression of alkaline phosphatase (ALP), and calcium deposition. We elucidated the osteogenic synergy observed on the nanoengineered surface: the gold layer generates responsive currents in response to a magnetic field, activating voltage-gated calcium channels (VGCC) and directly modulating osteogenic signaling. Meanwhile, the nanotopography of the silica layer (MSN) facilitates cell recruitment and adhesion, while the sustained release of alendronate loaded in MSN delivers potent pharmacological osteogenic stimulation. PEEK@MSN demonstrated superior osseointegration versus pristine PEEK, achieving 4.1-fold higher calcium deposition (2.67% → 16.30%) in vitro and 492% greater trabecular bone formation (0.075 → 0.308 mm) in vivo.

To further enhance their performance, an organomodified bentonite with known adsorption capacity was incorporated, yielding bionanocomposite hydrogels. All the systems were characterized in terms of morphology, chemical structure, thermal stability, and mechanical behavior. Adsorption performance of neat and optimal bionanocomposite hydrogel beads was evaluated using an ethylhexyl ester derivative of 2,4-dichlorophenoxyacetic acid (2,4-D), a widely used herbicide and representative emerging contaminant. Morphological analyses of the beads revealed robust core–shell architectures with smooth external surfaces and heterogeneous internal porosities, especially in biopolymeric blends. Thermal analysis confirmed enhanced stability with increasing cross-linking ions concentration and with the presence of CMC.

By adjustment of the ratio of nitrogen gas/air/oxygen, a gradient oxygen partial pressure environment (0/14.78/16.23/19.00/21.11/23.11/25.10 kPa) was constructed. Combined with Fourier transform infrared spectroscopy (FTIR), X-ray Diffraction (XRD), elemental analysis (EA), scanning electron microscopy (SEM), and Raman spectroscopy, the influence of oxygen partial pressure on the chemical structure, aggregated structure, and morphological structure of PAN fibers was analyzed. The research results indicate that oxygen can significantly promote dehydrogenation and oxidation reactions, which play a decisive role in forming stable aromatic structures. Higher oxygen partial pressure can facilitate oxygen diffusion, increasing the oxygen content in the fibers from 0.78 to 10.78% and reducing the optical density difference (ΔOD) from 3.389 to 2.547% by improving the uniformity of radial reactions.

Adhesion between printed metasurfaces and glass and between printed, self-complementary metasurfaces is studied above and below the cured resin’s glass transition temperature (∼45 °C). Simple heating of adhering surfaces to above 60 °C lowers adhesion, and compression of surfaces while above the glass transition temperature followed by cooling to room temperature elevates adhesion.
