“…After grafting (trace b), the stretching vibrations of CH 3 at 2918 cm −1 , C=O at 1720 cm −1 , and C–O (ring) at 905 cm −1 confirm the successful grafting of GMA onto UHMWPE fiber [ 28 ]. After phosphation (trace c), the absorption peak of C–O (ring) disappears, and fresh peaks of OH and P=O originate at 3100–3500 and at 930–1025 cm −1 , respectively, demonstrating the successful introduction of the phosphate group onto UHMWPE fiber [ 29 ].…”

This work provides a cost-effective approach for preparing functional polymeric fibers used for removing uranium (U(VI)) from carbonate solution containing NaF. Phosphate-based ultrahigh molecular weight polyethylene (UHMWPE-g-PO4) fibers were developed by grafting of glycidyl methacrylate, and ring-opening reaction using phosphoric acid. Uranium (U(VI)) adsorption capacity of UHMWPE-g-PO4 fibers was dependent on the density of phosphate groups (DPO, mmol∙g−1). UHMWPE-g-PO4 fibers with a DPO of 2.01 mmol∙g−1 removed 99.5% of U(VI) from a Na2CO3 solution without the presence of NaF. In addition, when NaF concentration was 3 g∙L−1, 150 times larger than that of U(VI), the U(VI) removal ratio was still able to reach 92%. The adsorption process was proved to follow pseudo-second-order kinetics and Langmuir isotherm model. The experimental maximum U(VI) adsorption capacity (Qmax) of UHMWPE-g-PO4 fibers reached 110.7 mg∙g−1, which is close to the calculated Qmax (117.1 mg∙g−1) by Langmuir equation. Compared to F−, Cl−, NO3−, and SO42− did not influence U(VI) removal ratio, but, H2PO4− and CO32− significantly reduced U(VI) removal ratio in the order of F− > H2PO4− > CO32−. Cyclic U(VI) sorption-desorption tests suggested that UHMWPE-g-PO4 fibers were reusable. These results support that UHMWPE-g-PO4 fibers can efficiently remove U(VI) from carbonate solutions containing NaF.

“…Titanium, albeit a transition metal ion plentifully encountered in industrial applications, has been increasingly drawing attention as a biomaterial component and potential metallopharmaceutical in a number of pathophysiological aberrations [35][36][37][38][39]. A serious impediment to such an effort is its natural propensity to drive aqueous reactivity toward the ultimate product TiO 2 .…”

The prospect of developing soluble and bioavailable Ti(IV) complex forms with physiological substrates, capable of influencing (patho)physiological aberrations, emerges as a challenge in the case of metabolism-related pathologies (e.g., diabetes mellitus 1 and 2). To that end, pH-specific synthetic efforts on binary Ti(IV)-(α-hydroxycarboxylic acid) systems, involving natural physiological chelator ligands (α-hydroxy isobutyric acid, D-quinic acid, 2-ethyl-2-hydroxybutyric acid) in aqueous media, led to the successful isolation of binary crystalline Ti(IV)-containing products. The new materials were physicochemically characterized by elemental analysis, FT-IR, TGA, and X-ray crystallography, revealing in all cases the presence of mononuclear Ti(IV) complexes bearing a TiO6 core, with three bound ligands of variable deprotonation state. Solution studies through electrospray ionization mass spectrometry (ESI-MS) revealed the nature of species arising upon dissolution of the title compounds in water, thereby formulating a solid-state–solution correlation profile necessary for further employment in biological experiments. The ensuing cytotoxicity profile (pre-adipocytes and osteoblasts) of the new materials supported their use in cell differentiation experiments, thereby unraveling their structure-specific favorable effect toward adipogenesis and mineralization through an arsenal of in vitro biological assays. Collectively, well-defined atoxic binary Ti(IV)-hydroxycaboxylato complexes, bearing bound physiological substrates, emerge as competent inducers of cell differentiation, intimately associated with cell maturation, thereby (a) associating the adipogenic (insulin mimetic properties) and osteogenic potential (mineralization) of titanium and (b) justifying further investigation into the development of a new class of multipotent titanodrugs.

The influence of polycaprolactone (PCL) and nano titanium phosphate, pristine (TiP) and Jeffamine™ modified (JETiP), was investigated in composites derived from recycled polypropylene/polycaprolactone/titanium phosphate (PPr/PCL/TiP and PPr/PCL/JETiP). The TiP was synthesized and chemically modified with amine and the composite processed in a Haake rheometer. Improvement of PPr thermal stability was revealed. Reduction of PPr cooling crystallization temperature (9°C) and crystallinity degree (∼5–10%) were registered. Hydrogen nuclear magnetic resonance time domain revealed enhance of molecular mobility which was associated to the diminution of PPr crystallinity. The X-ray diffraction pattern of the composite PPr/PCL/JETiP did not show phosphate diffraction angle. It was understood as polymer intercalation into modified titanium phosphate galleries. At low temperature, the storage modulus increased by the presence of PCL and phosphates evidencing reinforcement. Both PPr/PCL/TiP and PPr/PCL/JETiP composites yielded phase separation systems revealed by two peaks in the loss modulus curves. Also, the high PPr participation effectiveness degree on the PCL-rich phase was understood as owing to the interaction between PCL and phosphates.
