Summary: The study introduces a simple method to liquefy rare earth metals by incorporating the corresponding cations into polyvalent ionic liquids. It shows that these ILs have remarkably different properties despite the similarity of their cations, and possess interesting luminescent properties as non-conventional fluorophores.

Summary: The novel ionic liquids synthesized in this study show excellent extractability and selectivity for Nd(III) and Sc(III), as well as outstanding separation properties between rare-earth and first row transition-metal ions. The extraction mechanism indicates that the rare-earth complex extracted in the ionic liquid phase is structurally similar to those obtained with neutral extractants, providing a new approach for the future recycling of rare-earth metals.

Summary: Electrowinning is a clean process for neodymium metal recovery, but the current methods are limited by high energy consumption or high costs and environmental impact. In this study, new fluorine-free organic electrolytes were developed, enabling the electrodeposition of neodymium metal at room temperature. These electrolytes consist of solvated neodymium borohydride dissolved in ether solvents, prepared from non-fluorinated precursors. The electrodeposition of neodymium in these electrolytes demonstrated higher stability and was characterized to confirm the presence of neodymium metal.

Summary: The study synthesized two carboxylic acid-functionalized upper critical solution temperature (UCST)-type ionic liquids and investigated their efficient extraction and separation performance for scandium (Sc(III)) in aqueous solution. The results showed enhanced extractabilities of Sc(III) in homogeneous extraction, high selectivity for Sc(III) separated from other REEs, and the formation of Sc(III) complex via proton exchange. This provides a prototype for a highly efficient REE extraction system with potential applications for REE recovery from wastes.

Summary: Shape-persistent and conductive ionogels with enhanced mechanical strength and ionic conductivity are developed using a multiphase material composed of cellulose nanocrystals and hyperbranched polymeric ionic liquids. These ionogels possess outstanding mechanical strength and high compressive elastic modulus, while preserving the high ionic conductivity of original ionic liquids. The synergistic enhancement in ion transport and solid-like mechanical properties make these ionogels promising candidates for sustainable electrodeless energy storage and harvesting matrices.

Summary: Neodymium (Nd) was continuously extracted from aqueous solutions using trioctylphosphine oxide (TOPO) dissolved in the ionic liquid 1-Butyl-3-methylimidazolium Bis (trifluoromethanesulfonyl)imide ([C4mim][Tf2N]) in small channel contactors. The study confirmed a 1:6 Nd:TOPO extraction mechanism at high initial Nd concentrations in a nitric acid aqueous phase. The effects of mixture velocity and residence time on the extraction efficiency and mass transfer coefficient were investigated.

Summary: Two series of Eu-doped (Sr,Ln)(9)MgK(PO4)(7) solid-solution phosphors were synthesized and their crystal structure and luminescence properties were studied. The luminescence of Eu3+ and Eu2+ ions were observed in Eu-doped Sr9MgK(PO4)(7) phosphor synthesized in a reducing atmosphere. The incorporation of Y3+ and La3+ ions, as representatives of rare earth ions, significantly improved the luminescence performance, indicating the stabilization of Eu2+ ions under reductive atmosphere. The proposed strategy proves to be feasible for other Eu2+/3+-coexisting phosphor systems.

Summary: Currently, there is a significant lack of knowledge in the research of rare earth exploitation, particularly in terms of carbon emission coefficient. This study utilizes the life cycle assessment approach to compute the carbon footprint of producing mixed oxide rare earths using ionic rare earth resources and analyze the sources and influencing factors of this carbon footprint. The findings indicate that the carbon footprint of producing 1 kg of mixed oxide rare earths using ionic rare earths ranges from 17.8 to 24.3 kg CO2 eq with an uncertainty of 15.54%. The total carbon footprint from 2012 to 2017 reaches 1.6 x 10(8) to 2.19 x 10(8) kg CO2 eq/year, and decreases to 1.51 x 10(8) to 2.07 x 10(8) kg CO2 eq/year after 2018. The carbon footprint of illegal mining is approximately 1.50 x 10(8) to 1.59 x 10(8) kg CO2 eq/year. Generally, a higher recovery rate leads to a lower carbon footprint of 1 kg REO production, but the benefit of carbon footprint reduction diminishes as the recovery rate increases. Finally, the new generation of magnesium salt leaching technology, while mitigating ammonia nitrogen pollution in ionic rare earth mines, will increase the carbon footprint of the product.

Summary: The study demonstrates that ionic liquid can improve the dispersion of cellulosic nanofillers and enhance the mechanical strength of vulcanizates. As the concentration of cellulosic nanofillers and ionic liquid increases, the viscoelastic rheological behavior of the vulcanizates is also affected.

Summary: In this study, flower-like and linear-like YVO4:Eu3+ hollow mesoporous spheres were synthesized and connected with Eu organic ligand, leading to the formation of a new hybrid luminescent material. The hybrid material showed higher emission intensity compared to single YVO4:Eu3+ and single Eu complexes, achieving mutually reinforcing luminescence. This paper presents a new approach to connect rare earth complexes for the fabrication of non-silicon-based mesoporous spherical matrix.

Summary: In this study, a photo/sono-responsive nanoplatform was developed for photoacoustic/photothermal bimodal imaging-guided sonodynamic therapy (SDT) using TiO2-x nanoparticles synthesized on the surface of two-dimensional MXene. The nanoplatform showed enhanced reactive oxygen species (ROS) generation due to charge trap effect of the TiO2-x nanoparticles and tumor hypoxia relief through localized hyperthermia induced by the Ti3C2 nanosheets. The dual-stimuli nanoplatform achieved substantial cellular killing in vitro and complete tumor eradication in vivo.

Summary: This study presents a glucose oxidase-engineered nanoplatform for activatable imaging-based companion diagnostics and multistage augmented photothermal/starvation synergistic therapy. The nanoplatform utilizes a pH-activatable conjugated polymer as a photothermal converter and photoacoustic emitter, glucose oxidase as a cancer starvation inducer, and a H2O2-cleavable linker as a switch for enzyme activity. The in vivo imaging and therapy abilities are activated by the acidic tumor microenvironment and self-augmented by the reaction between glucose oxidase and glucose.

Summary: The widespread use of organic arsenic pesticides and veterinary drugs has drawn attention, as their photochemical transformation in surface water contributes to degradation and the formation of products. This study investigates the effect of co-existent components, such as EDTA, on the photochemical transformation, and finds that the Fe(III)-EDTA complex exhibits photoactivity under both UVA light and simulated sunlight. Appropriate amounts of EDTA enhance the photodegradation efficiency, while excessive amounts suppress the reaction rate.
