Summary: Efforts are being made to enhance the reactivity of ferrate by generating highly reactive iron intermediates (Fe-V and Fe-IV) from the tetraoxy anion of iron in the +6 oxidation state. Various strategies, such as addition of acid, metal ions, and reductants, are utilized to produce Fe-V and Fe-IV species for more efficient treatment of polluted water. Kinetic modeling and DFT calculations provide opportunities to distinguish between Fe-IV and Fe-V in order to improve oxidation reactions using ferrate.

Summary: A novel composite (nZVI/HNTs) was prepared by incorporating nano zero-valent iron (nZVI) on halloysite nanotubes (HNTs) for degrading tetracycline hydrochloride (TCH) with the presence of persulfate (PS). The nZVI/HNTs + PS system exhibited satisfactory degradation efficiency (84.21%) for TCH, and stable nZVI/HNTs could be reused. The quenching tests and EPR analysis showed that SO4- was the dominant quencher instead of OH in this system. Three possible pathways of TCH degradation were identified through LC-MS determination. Additionally, the biological toxicity prediction analysis indicated that the nZVI/HNTs + PS system is an environmentally friendly treatment method for TCH pollution.

Summary: The development of highly active and stable non-noble metal-nitrogen ringcomplex (M-N-C) catalysts for the oxygen reduction reaction (ORR) is important. However, M-N-C catalysts are typically prepared through high-temperature pyrolysis, resulting in complex product structures and difficulties in identifying the catalytic active center.

Summary: Polyethylene terephthalate (PET) with its negatively charged surface repels bacteria but lacks direct antibacterial activity. Alkali-treated PET nanofibers, also negatively charged due to carboxyl groups, surprisingly exhibit remarkable antibacterial properties (89% and 75% antibacterial rate against S.aureus and E.coli, respectively). The increased carboxyl groups on the fiber surface induced by alkali-treatment attract positively charged cetyltrimethylammonium ions (CTA+), which can efficiently inactivate the bacteria by forming stable electrical double layers (EDL). An effective heavy-metal free antibacterial fiber has been developed by loading iron-phthalocyanine to the nanofibers, which can inactivate bacteria under dark conditions by utilizing surface CTA+ and weak reactive oxygen species.

Summary: Titanium dioxide (TiO2) nanoparticles have been widely used to modify the optical properties of materials, especially polymer fibers, to reduce light reflection. In this study, the 3D microstructure of TiO2/poly(ethylene terephthalate) nanocomposite fibers was directly obtained using focused ion beam-scanning electron microscopy (FIB-SEM) with a resolution of 20 nm. It was found that TiO2 nanoparticles show significant agglomeration in the in situ-polymerized fibers, contrary to common understanding. The slightly increased particle size may contribute to enhanced light-extinction properties due to altered Mie scattering with incident visible light.

Summary: This study demonstrates the improvement of mechanical properties and reduction of coefficient of thermal expansion (CTE) in graphene oxide (GO)/epoxy (EP) nanocomposites by enhancing the interface between GO and EP through functionalization and incorporating rigid-flexible interphases. The results reveal that the SiO2-PEA-GO hybrid exhibits better strengthening and toughening effects, as well as lower CTE, compared to the PEA-GO hybrid due to the presence of rigid-flexible interfaces with higher bonding strength and better energy dissipation mechanisms. Additionally, the nanocomposites with longer polyetheramine (PEA) molecules in the rigid-flexible interphases demonstrate higher strength and toughness, while maintaining a lower CTE. This work provides a promising strategy for constructing adjustable flexible-rigid interfacial structures and offers potential in developing GO/EP nanocomposites with high mechanical properties and low CTE.
