Summary: In this study, an enantioselective artificial architecture was constructed on TiO2 nanochannels, using homochiral Ti-based metal-organic frameworks (MOFs) as the skeleton, Fe(III) as peroxidase-mimicking centers, and L-tartaric acid (TA) as a chiral recognition selector. The selective recognition of cystine enantiomers was achieved through hydrogen bonds formed between chiral cystine and the host, and the change in peroxidase-like activity of the nanochannels was monitored through ionic current signatures.

Summary: A linker extension strategy is proposed to generate metal-organic frameworks (MOFs) with enhanced moisture-capturing properties. The design approach results in MOF-LA2-1 {[Al(OH)(PZVDC)], featuring a 50% increase in water capacity compared to MOF-303, the state-of-the-art water-harvesting material. The strategy not only increases the pore volume of the MOF, but also retains its ability to capture and release water in arid environments, while reducing regeneration heat and temperature.

Summary: Flue gas desulfurization is crucial for human health and ecological environments. Developing efficient SO2 adsorbents that can balance adsorption capacity and selectivity is still challenging. In this work, a new type of fluorinated anion-pillared metal-organic frameworks (APMOFs) is fabricated, with high porosity and density of fluorinated anions, ensuring exceptional SO2 adsorption capacity and ultrahigh selectivity for gas mixtures. The APMOFs also show excellent stability and cyclic performance. This research provides guidance for designing porous materials for flue gas desulfurization and other gas purification processes.

Summary: In this study, two isoreticular pillar-layer metal-organic frameworks, Co(aip)(bpy)0.5 and Co(aip)(pyz)0.5, were developed for the separation of C2H4/C2H6. The pore apertures of these frameworks are controlled by changing the length of the pillar ligands. Co(aip)(pyz)0.5, with a shorter pillar ligand, shows reduced pore size and molecular sieving separation of C2H4 from C2H6. Molecular simulation and dynamic breakthrough experiments confirm its high selectivity for C2H4.

Summary: In this study, sodium diphenyl ketone (Na-DK) was used to presodiate the hard carbon (HC) anode for sodium-ion batteries, improving its initial Coulombic efficiency and stability. Na-DK achieved dual-function presodiation by compensating the irreversible sodium uptake at oxygen-containing functional groups and reacting with carbon defects in HC. The resulting sodium induced a robust sodium fluoride (NaF)-rich solid electrolyte interphase (SEI) on HC, promoting interfacial reaction kinetics and stable sodium insertion and extraction. This work demonstrated high capacity retention of approximately 100% and 82.4% after 6800 cycles for presodiated HC (pHC) and full cells with Na3V2(PO4)3 cathodes, respectively. It provides valuable insights into chemical presodiation and offers a new strategy for highly stable sodium-ion batteries.

Summary: This study attempts a solvation-regulated strategy in tetraethylene glycol dimethyl ether (G4) based electrolyte to achieve stable lithium anodes in Li-O-2 batteries. By incorporating trifluoroacetate anions (TFA(-)) with strong Li+ affinity into the lithium bis(fluorosulfonyl)imide (LiTFSI)/G4 electrolyte, the Li+-G4 interaction is attenuated and anion-dominant solvates are formed. The bisalt electrolyte with 0.5 M LiTFA and 0.5 M LiTFSI mitigates G4 decomposition and induces an inorganic-rich solid electrolyte interphase (SEI), leading to improved Li+ diffusion and extended lifespan in Li-O-2 batteries.

Summary: This study demonstrates that regulating the chelating power and coordination structure can significantly enhance the high-voltage stability of ether-based electrolytes and the lifespan of lithium metal batteries. The use of 1,3-dimethoxypropane (DMP) and 1,3-diethoxypropane (DEP) as solvents in the electrolytes instead of the traditional 1,2-dimethoxyethane (DME) results in the formation of weak Li solvates, contributing to improved reversibility and high-voltage stability in lithium metal batteries. The fabricated high-voltage Li||LiNi0.8Co0.1Mn0.1O2 lithium metal batteries using 2.30 M Lithiumbisfluorosulfonimide (LiFSI)/DMP electrolyte show excellent capacity retention over 90% after 184 cycles, even under lean electrolyte and low anode to cathode ratio conditions.

Summary: In this study, the facet selectivity of commonly used Cu current collector for Li metal electrodeposition was investigated using density functional theory (DFT) and ab initio molecular dynamics (AIMD) simulations. Nine Li-Cu interfaces composed of low-index crystal facets were evaluated for stability based on descriptors such as adsorption energy, lattice mismatch, formation energy, and diffusion constant of lithium atoms. The results indicate that Cu(100) and Cu(110) surfaces are preferential for the growth of Li(100) in Li crystal facets (100), (111), and (100), while Cu(111) surface prefers forming Li(110). It is suggested that Cu(110) may be superior to Cu(100) and Cu(111) for Li deposition, providing a useful guideline for improving the efficiency of Li deposition by controlling the morphology of the current collector.
