New tetrasubstituted porphyrin tin complexes (5–14) were prepared in two different ways: In the first preparation procedure, by a direct reaction of butyltin trichloride and dibutyltin dichloride with tetra/tetrakis(4-X-phenyl)porphyrins (X = H, F, Cl, Br, CF3, CH3O, (CH3)2N). second same synthesized from lithium porphyrinato derivatives. These novel characterized elemental analysis, 1H, 13C NMR, FTIR, UV-Vis spectroscopy, mass spectrometry. Among these complexes, containing methoxy group [Bu2Sn(TMOPP)] was tested as an adsorbent to remove tetracycline antibiotics wastewater. The TTC antibiotic removal efficiency (R%) this complex measured using spectroscopy. After 120 min equilibration, final R% adsorption capacity (qt) at 60.15% 18.10 mg/g, respectively.

Carbon-14 (14C), a radionuclide generated in nuclear power plant's operation, is serious environmental threat due to its long half-life (5730 years) and potential mobility the environment. Herein, we present sequestration behavior of inorganic 14C as carbonate (CO32–) bicarbonate (HCO3–) species from simulated waste solution using synthesized ettringite under various experimental conditions. The was via route characterized by XRD, FT-IR, N2 adsorption/desorption isotherms, FE-SEM/EDS analyses. Synthesized exhibited an efficient removal capacity (∼92–94%) compared CO32– HCO3– anions solution. mechanism for suggested that achieved ligand exchange framework dissolution–precipitation, respectively. To investigate retention onto ettringite, study also performed desorption experiments groundwater (SGW) obtained results % both significantly lowered (7 4.5% anions, respectively) SGW. We believe our will be highly significant interpreting immobilization dissolved alkaline solutions/aqueous environments.

ABSTRACT Artificial implants are necessary for orthopedic treatment and the recovery of bone joint function in disabled individuals. However, existing materials present challenges manufacturing complex structures limited terms mechanical frictional properties. Current research is focused on development new environmentally friendly polymer composites manufacture artificial implants, combined with 3D printing technology to improve design flexibility. In this study, nine kinds PLA/n‐HA/PA66 composite scaffolds different proportions were prepared using light‐curing technology. The physical, mechanical, tribological properties compared. results showed that scaffold was superior traditional polymers, compressive strength increased by 30–40 MPa wear resistance 27%–64%. This indicates it has wide application potential tissue engineering.

ABSTRACT Currently, mainstream phthalate plasticizers pose serious threats to the environment and human health. As an eco‐friendly harmless alternative, polyester have garnered widespread attention. However, their complex preparation process low plasticizing efficiency limited practical application. In this study, a series of copolyester (POMAZ), synthesized from azelaic acid, octanediol, various contents 2‐methyl‐1,3‐propanediol (MPO), were prepared via direct esterification. The is controllable, number‐average molecular weight POMAZ ranges 1000 4000, with thermal degradation temperature above 270°C, demonstrating excellent stability. PVC samples plasticized showed decrease in glass transition −30°C increased hydrophilicity higher MPO content. Measurements tensile elongation at break verified outstanding performance series. Specifically, POMAZ‐45/PVC exhibited up 975.3%, reaching 273.2%.
