[Display omitted] • Calculation-guided structure optimization was used to redesign Lns/Ans separation ligand. • Phenanthroline diamide ligands were prepared to reduce the rotation barriers for coordination. • Record high separation factors of SF Eu(III)/Am(III) were reported in n -octanol in high acidity. • Well-balanced extraction/stripping/recycling were demonstrated. Liquid-liquid extraction is the most wildly adopted industrial Lns/Ans separation approach which takes advantages of the subtle atomic size differences for Lns and Ans. Preorganized ligand architecture with coordination configuration locking strategy has been proven to be very efficient to enhance the separation factors by size exclusive effect from the preset ligand cavity while drawbacks such as sophisticated ligand synthesis, unbalanced extraction/stripping performances and limited solubility in environmental benign solvents prevent the economic practicability. In the current contribution, calculation-guided ligand structure optimization was utilized to optimize the hard/soft tetradentate phenanthroline diamide ligands. Reducing the number of alkyl chains around the binding sites from amide to imide led to less rotation energy barriers, eventually boosted both metal distributions and separation factors. Additionally, the formation of hydrogen bonds in the imine ligands enhanced their solubility in industrial-friendly solvent, such as n -octanol, leading to superior extraction performances. Finally, balanced extraction, stripping and recycling of the reported ligands were demonstrated to unravel the potential to be integrated into current industrial plants. The ligand design philosophy as discussed in this work could inspire the searching for new environment-friendly high-performance lipophilic ligand to close the current nuclear fuel cycle.

An in situ reversible assembly strategy is demonstrated for the fabrication of p-n heterojunctions in BiOI/Bi 5 O 7 I composites. This approach allows for the generation of ample interfacial interactions and built-in electric field, resulting in a strong driving force for effective charge separation. These advantages drastically enhance the photocatalytic activity of BiOI/Bi 5 O 7 I composites towards efficient CO 2 reduction and pollutants degradation using visible light. [Display omitted] • In-situ reversible assembly strategy to fabricate BiOI/Bi 5 O 7 I p–n heterojunctions. • BiOI/Bi 5 O 7 I p–n heterojunctions provide ample interfacial interaction. • These advantages enable efficient visible-light photocatalysis for CO 2 reduction. • Theoretical and experimental studies reveal insights on interfacial charge transfer. Constructing efficient p-n heterojunctions holds great potential in the realm of photocatalysis for promoting the sustainable development of the environment and energy industries. However, traditional p-n heterojunctions suffer from limited interfacial interaction which severely restricts the effectiveness of the built-in electric field in boosting charge separation. Herein, we present an in situ reversible assembly approach to fabricate functional p-n junction in BiOI/Bi 5 O 7 I composites at room temperature. By controlling the reaction time or the amount of KI precursor added, we attain the as-designed BiOI@Bi 5 O 7 I and Bi 5 O 7 I@BiOI heterojunctions with large specific surface area and ample interfacial electric field. Subsequent application of the optimized heterojunction material as visible-light photocatalyst achieves efficient photoreduction of CO 2 reactant into CO product (0.46 μmol g−1h−1), even without using any sacrificial agent in the gas–solid reaction system. This catalytic performance is notably ∼ 6.6 times and 15.3 times higher than that of standalone BiOI and Bi 5 O 7 I materials, respectively. In situ XPS, in situ Kelvin probe force microscopy, and theoretical calculations reveal that the built-in electric field induces directional charge transfer to greatly boosts the efficiency of separating photogenerated electron-hole pairs at the interface of BiOI and Bi 5 O 7 I. This study provides valuable insights for the rational design and straightforward fabrication of next-generation, integrated heterostructured photoelectronic materials for efficient energy, environmental, and chemical applications.

[Display omitted] • FeNi or FeCo@N-doped graphene layer core–shell heterojunctions/N-doped carbon nanorods/rGO composites were synthesized. • The filler loading and rGo could effectively adjust the permittivity. • The strong absorption was achieved of −52.61 dB and −59.42 dB. • The effective absorption bandwidths were up to 4.64 GHz and 5.28 GHz. Rational construction of heterogeneous interfaces is an effective strategy to explore high-performance electromagnetic waves (EMWs) absorption materials. Herein, we adopt a facile solvothermal and pyrolysis process to fabricate the multicomponent and multidimensional composites containing the bimetallic FeNi or FeCo@N-doped graphene layer core–shell heterojunctions/N-doped carbon nanorods/reduced graphene oxide (FeNi@NC/NCR/rGO or FeCo@NC/NCR/rGO) derived from NH 2 -bimetallic (FeNi or FeCo)-metal organic frameworks (MOFs)/GO precursors. The excellent EMWs absorption performances are effectively achieved and regulated via the content of rGO and the filler loading. Compared with the case without rGO, the FeNi@NC/NCR/rGO composite (25 wt% filler loading) displays a strong reflection loss (RL) of −52.61 dB at 14.44 GHz with a thin thickness of 1.65 mm, and effective absorption bandwidth (EAB) is 4.64 GHz. And the FeCo@NC/NCR/rGO composite (20 wt% filler loading) displays a strong RL of −59.42 dB at 17.8 GHz with a thinner thickness of 1.42 mm, and EAB is 5.28 GHz at 1.66 mm. Their excellent absorption properties result from the synergistic effect between the increased dielectric loss (interfacial polarization, dipole polarization and conduction loss), impedance matching and attenuation constant. These results provide a pathway to prepare the multicomponent and multidimensional composites with superior EMWs absorption. [ABSTRACT FROM AUTHOR]

[Display omitted] • A 3D superstructure is composed of 2D MXene and 1D N-CNT derived from Ni-MOF. • The optimal RL of nanocomposite reached −57.78 dB with thickness of 1.49 mm. • Nanocomposites exhibit excellent and adjustable absorption in C and X band. • Performance enhancement is due to synergistic effect under 3D superstructure. Developing an expandable microstructure method to acquire high-performance microwave absorbers is an effective strategy to prevent electromagnetic wave radiation pollution. In this study, a three-dimensional (3D) conductive network is constructed using 1D carbon nanotubes (CNTs) derived from Ni (hollow and solid microsphere structure) metal–organic-frameworks (MOFs) and 2D Ti 3 C 2 T x MXene simultaneously to form a superstructure composite material. The results of the experiment and analysis confirm the successful synthesis of 3D superstructure composites with excellent microwave absorption (MA) properties. The optimal reflection loss (RL) is − 57.78 dB with a thickness of 1.49 mm at 8.4 GHz, and the maximum effective absorption bandwidth is 3.44 GHz for a thickness of 0.8 mm. In the unique 3D superstructure, microwave attenuation capacity and impedance matching are optimized under the synergistic effect of multiple resonances and polarization relaxation. Simultaneously, adjustable and efficient MA between the C and X bands is achieved by modulating the loading of the Ni particle hybrid. It is anticipated that this superstructure composite material can be used for a new generation of microwave absorbers. [ABSTRACT FROM AUTHOR]

• A novel approach to prepare supramolecular high adhesion 3,5-BTP-PDMS-4 elastomer. • The 3,5-BTP-PDMS-4 obtained high adhesion force, high Young's modulus and energy-containing property. • The 3,5-BTP-PDMS-4 could complete autonomous self-healing at a low temperature of 0 °C. • The 3,5-BTP-PDMS-4 suitable for military applications. Self-healing materials are used in various applications because of their capacity to prolong the material's longevity and durability. Several important properties, including high adhesion force to various surfaces and mechanical robustness have the potential to further expand their application in various fields. In this study, we designed an energy-containing and high-adhesion elastomer (3,5-BTP-PDMS-4), which was fabricated via the click polymerization, that could self-heal at −20 °C. The prepared polymer adhesive exhibited prominent mechanical strength with a high Young's modulus of up to 17.91 MPa. The material also showed that it could autonomously and completely self-heal and restore its mechanical properties within 6 h at room temperature when the 3,5-BTP-PDMS-4 sample was cut into two separate pieces. Moreover, this material was found to possess a high adhesion force of up to 1.65 MPa on steel, which increased when the temperature was reduced. Furthermore, we prepared TATB-based PBXs using 3,5-BTP-PDMS-4 as a binder because of its energy-containing property and excellent self-healing properties to heal cracks generated during fabrication, transportation and storage. Surprisingly, the TATB-based PBXs achieved complete self-healing at 0 °C and partial self-healing at −20 °C, although the low plastic explosive crystals were detrimental to the material's self-healing properties. The successful development of a polymer adhesive that has a high-Young's modulus and can autonomously and completely self-heal could help expand its applications with enhanced versatility in several fields, including military and civil applications.
