Summary: Sulfonated polymers are widely used in fuel cells as proton-conducting materials and their ionic transport features make them attractive for electrolytes in lithium-ion/metal batteries. This study demonstrates the use of swollen nanofibrous Nafion as effective Li+-conducting channels, which enhances Li+ transport by forming a porous ionic matrix and promoting partial desolvation of Li+-solvates. The application of this membrane in Li-symmetric cells and Li-metal full cells shows excellent cycling performance and stabilized Li-metal anode, providing a strategy to convert sulfonated polymers into efficient Li+ electrolytes and promoting the development of high-energy-density LMBs.

Summary: Layered transition-metal oxides have been considered as potential high-performance cathode materials for sodium-ion batteries (SIBs). However, the undesirable side reactions at the cathode/electrolyte interface during cycling have limited their applications. In this study, a high-rate P2-Na2/3Ni1/3Mn2/3O2 cathode material for SIBs was developed by optimizing the surface coating using Al-doped ZnO (AZO). The optimized cathode material, coated with 1 wt% AZO at 500°C, exhibited good cycling and rate performances.

Summary: Alternatives to tin-doped indium oxide transparent electrodes are required. Tungsten-doped SnO2 thin films with low resistivities and high electron mobilities were obtained using chemical vapor deposition. The tungsten dopant had minimal distortion to the SnO2 unit cell and resulted in crystallographic preferential orientation in the [200] direction. X-ray photoelectron spectroscopy analysis indicated that tungsten was present in the +5 state, minimizing ionized impurity scattering and achieving high electron mobilities. The tungsten-doped films had an optical band gap of 3.7 eV, making them transparent to visible light.

Summary: With the increasing demand for renewable energy, alkali metal-ion batteries, specifically using lithium, sodium, and potassium ions, are becoming more crucial in static storage and the electric vehicle industry. Antimony oxides (SbxOy) exhibit electrochemical reaction activity with all three alkali metal ions and hold great potential as anodes for alkali metal-ion storage due to their high capacity, suitable operating potential, and excellent safety properties. This review provides an overview of the research progress on the reaction mechanism and improvements in electrochemical performance of antimony oxides for alkali metal-ion storage, while also discussing their future prospects.

Summary: Porous nitrogen-doped carbon nanocages (PNCCs) were synthesized by one-step pyrolysis of energy-efficient Zn-based MOF (MET-6), and demonstrated high efficiency as PMS activators for decomposing organic micropollutants. PNCCs-900 exhibited remarkable catalytic activity for RhB degradation due to its high specific surface area (894.9 m(2) g(-1)), nitrogen doping level (13.1%), and optimal nitrogen configuration ratio. This study opens up a new avenue for the development of efficient PMS activators for water remediation.

Summary: Through the preparation of a series of SrCo1-xFexO2.9-delta F0.1 (x = 0, 0.1, 0.2, and 0.3) perovskites, it was found that the ferromagnetism of Fe-doped samples is influenced by Fe4+-O-Co3+, Fe3+-O-Fe3+, and Fe4+-O-Fe4+ interactions, leading to a decrease in the magnetic transition temperature, while the resistivity data can be better fitted using Mott's variable range hopping (VRH) model, implying its disordering semiconducting behavior.

Summary: The increased degree of graphitization is commonly accepted to enhance the electrical conductivity of carbon materials. However, heteroatom doping on carbon host can also improve the conductivity by contributing to higher charge delocalization and density of donor states near Fermi level. This study demonstrates that nitrogen-doped carbon with finely designed structure exhibits an electrical conductivity over 3.5 times higher than commercial carbon conductors, making it a promising conductive agent-free electrode material for all-solid-state flexible supercapacitors.

Summary: Controlling the nucleation step of a self-assembly system is crucial for engineering structural complexity and dynamic behaviors. This study investigates the inherent dynamics of three general nucleation modes in DNA tile-based self-assembly and reveals temperature-dependent kinetics and a nucleation-growth model are key factors. The assembly of tiles can be externally regulated by the hosting frame and an UV-responsive trigger, offering a general strategy for controlling the self-assembly process.

Summary: A three-dimensional DNA rack (DR) structure is proposed to assemble single emitters within ultra-small plasmonic nanocavities formed by closely coupled gold nanorods (AuNRs) with high precision. The unique saddle shape of DR allows linear alignment of AuNRs with tight gaps, resulting in nanocavities with high Q factors. By incorporating a DNA docking strand, single fluorescent emitters can be positioned within the nanocavities, leading to significant enhancements in fluorescence intensity and reduction in emission lifetime, demonstrating strong emitter-cavity interactions.
