Summary: Vanadium oxide/carbon composite materials show promising potential as electrodes for sodium ion batteries due to their high specific capacity and long cycling life. The insertion of calcium ions helps maintain material stability and conduct sufficient redox reactions. Uniform carbon coating enhances electrochemical stability and specific capacity by increasing material conductivity and inhibiting adverse side effects, leading to excellent electrochemical performance with high capacity retention rates even after multiple cycles.

Summary: A two-dimensional bilayered V2O5 center dot nH2O nanomaterial with Zn2+ intercalation was synthesized via a facile sol-gel method combined with vacuum freeze-drying. The microstructure and surface morphology were characterized by XRD, EDS, XPS, and SEM measurements. The Zn2+ intercalation resulted in the formation of a layer-by-layer stacked sheet-like morphology and promoted the presence of V4+ states in V2O5 center dot nH2O. Compared to the pure sample, the V2O5 center dot nH2O sample with Zn2+ intercalation showed improved rate capability, cycling stability, Na+ diffusivity, and reduced electrochemical reaction resistance.

Summary: In this study, a new dual-ion-in-sequence intercalation strategy is proposed to address the structural instability and sluggish diffusion kinetics of vanadium oxides in ZIBs. The Zn2+ storage mechanism evolves from solid-state ion diffusion kinetic into intercalation pseudocapacitance, resulting from the enlarged interlayer spacing. The improved ionic diffusivity, intercalation pseudocapacitance, and fast charge transferability contribute to the impressive rate capability and cycling stability of the ZIBs.

Summary: This study uses aliphatic diamines as pre-intercalated guests to elastically modulate the interlayer spacing of V-O layers by tuning the chain length of the organic diamine molecules. The strong interaction between the aliphatic diamine molecules and V-O layers serves as a structural stabilizer between the layers and enhances fast Na ion diffusion. The sodium ion battery based on the synthesized 1,6-hexanediamine pre-intercalated vanadium oxide achieves a high specific capacity, superior rate performance, and cycling stability.

Summary: This study establishes a quantified relation between ligand-metal bond covalency and oxygen-redox electrochemistry using Li2Ru1-xMnxO3 compounds. The results show a linear positive correlation between the transition metal (TM)-O bond covalency and the overlap area of TM nd and O 2p orbitals. Additionally, the enhanced TM-O bond covalency improves the reversibility of oxygen-redox electrochemistry, as demonstrated by electrochemical tests on the Li2Ru1-xMnxO3 systems. The designed Ru-doped Li-rich Li1.2Mn0.54Ni0.13Co0.13O2 cathode exhibits enhanced initial coulombic efficiency, increased capacity retention, and suppressed voltage decay during cycling. This systematic study provides a rational structure design principle for the development of oxygen-redox-based layered oxide cathodes.

Summary: The study synthesized two VOP compounds as cathode materials for aqueous Zn-ion batteries, showing highly reversible Zn-ion intercalation and deintercalation. While VOPO4.2H(2)O achieved a higher specific capacity during discharging, [H-0.6(VO)(3)(PO4)(3)(H2O)(3)].4H(2)O demonstrated greater stability and reproducibility during cycling. Further research is needed to improve the specific capacity and cycling performance of VOP-based cathodes for potential use in aqueous ZIBs.

Summary: Sodium layered oxides are characterized by high capacity and varied composition, but they suffer from limited kinetics and interfacial instability with residual alkali. The conventional methods of substitution/doping and heterogeneous coating are insufficient to address both bulk and surface issues. Therefore, a post-substitution strategy is proposed to modify primary sodium-layered-oxide particles, which can simultaneously deal with bulk and surficial issues.

Summary: This study focused on the semihydrogenation of acetylene in an ethylene-rich stream using two alloyed Pt catalysts PtCu and PtCo. The PtCu catalyst showed higher activity and ethylene yield compared to PtCo due to its higher unoccupied Pt d-orbital density. This indicates that alloying Pt with Cu is more promising for industrial relevant SHA catalyst.

Summary: This work presents a continuous solvent extraction method for the separation of cobalt and nickel in a millifluidic system using Cyphos IL 101 (C101) as the extractant. The optimal conditions for extraction performance and solvent properties were determined by investigating the effects of channel length, flow rate, and temperature. The performance of a developed manifold structure was compared to a single-channel system, and excellent separation results were achieved. The continuous separation process using the manifold structure resulted in high purity cobalt and nickel products.

Summary: The use of machine learning to predict the performance of specific adsorbents in phosphate adsorption shows great promise in saving time and revealing underlying mechanisms. However, the small size of the dataset and insufficient detailed information limits the model training process and the accuracy of results. To address this, the study employs a fuzzing strategy that replaces detailed numeric information with descriptive text messages on the physiochemical properties of adsorbents. This strategy allows the recovery of discarded samples with limited information, leading to accurate prediction of adsorption amount, capacity, and kinetics. The study also finds that phosphate uptake by adsorbents is generally through physisorption, with some involvement of chemisorption. The framework established in this study provides a practical approach for quickly predicting phosphate adsorption performance in urgent scenarios, using easily accessible information.
