Summary: In this study, polyethyleneimine functionalized magnetite nanoparticles (PEI-MNPs) with well-defined core-shell structures were prepared by a Layer by-Layer (LbL) approach using sodium tripolyphosphate (STPP) as a cross-linker. The as-prepared PEI-MNPs showed improved adsorption capability towards fucoidan at pH 4-8 due to the high density of cationic groups on the surfaces and the absence of internal pores. The PEI-MNPs loading with fucoidan can be isolated from the final products by a neodymium magnet and regenerated by 4 M NaCl solution as stripping reagent.

Summary: A supramolecular hydrogel with superior stability and mechanical strength was fabricated through hydrogen bonding interactions between polyethyleneimine and cellulose nanofibers under acidic conditions. The hydrogel showed a maximum uranium uptake capacity of 641 mg-U/g at pH=7 and exhibited high tolerance towards interfering metal cations. The uranium uptake occurred through adsorption and subsequent deposition, where the adsorbed uranyl ions combined with local hydroxide ions induced by polyethyleneimine. This supramolecular hydrogel, with its easy fabrication and cyclic utilization, has great potentials for uranium removal and recovery from uranium-containing wastewater.

Summary: Uranium extraction from radioactive nuclear waste is crucial for sustainable energy supply and ecological security. The synthesized 0.4-PEI/ECH-CTS composite microspheres show high uranium adsorption capacity of 380.65 mg g-1 within 4 hours due to their high nitrogen content. The microspheres exhibit excellent performance in removing U(VI) from simulated nuclear wastewater with 100% efficiency and reducing the concentration of CU(VI) to well below the limit set by the US Environmental Protection Agency for drinking water. The 0.4-PEI/ECH-CTS microspheres maintain above 95% adsorption efficiency after multiple cycles, making them highly suitable for practical industrial applications.

Summary: The interaction between brominated flame retardants (BFRs) and transition metal oxides is widely used in the thermal recycling of bromine-contaminated plastics. This study investigated the thermal degradation behavior of hematite (Fe2O3): tribromophenol (TBP) mixtures during co-pyrolysis and co-combustion using a thermogravimetric analyzer (TGA). The obtained thermo-kinetic parameters provide insights into the reduction of activation energy by hematite and the mechanism of debromination of TBP. The results have direct applications in reactor modeling and heat transfer design for the recycling of electronic waste.

Summary: Post-transition metal-based liquid alloys are used as media for efficient chemical reactions, and the solute metals show high reactivity. This study focuses on the synthesis of zinc-organic frameworks using liquid alloys. Density functional theory calculations reveal that zinc atoms in the gallium-zinc system are reactive and likely to ionize. The liquid metal-based approach is shown to produce a stratified structure of the zinc-organic framework under mild conditions. A continuous liquid metal-based reactor is also demonstrated for synthesizing the stratified zinc-organic framework.
