Summary: This work reports the synthesis of Bi1-xSrxFeO3 (SBFO; x = 0.0, 0.15, 0.25, 0.35) nanoparticles by solgel method and investigates their structural and piezoelectric properties. The study reveals the phase transformation from rhombohedral to cubic of BiFeO3 upon Sr doping, as well as the enrichment of oxygen vacancies in Sr-doped BiFeO3 nanoparticles. The SBFO-PENG device with 25% Sr content shows the highest maximal polarization value and remnant polarization, along with improved output voltage and current compared to a bare BiFeO3 PENG. It also demonstrates high mechanical robustness and stable output even after extended periods of operation. The feasibility of the SBFO-PENG device is demonstrated by successfully triggering commercial electronics and energy storage in a capacitor.

Summary: Multi-layer ceramic capacitors with high recoverable energy storage density and large energy efficiency play a crucial role in modern electronic devices. Various ferroelectric ceramic materials with relaxor characteristics and large dielectric constant are the most favorable candidates for achieving superior energy storage performance. In this study, a novel lead-free (1-x)Ba0.80Ca0.20TiO3-x(Bi0.80Mg0.20)(Ti0.65Mg0.30)O-3(BCT-BMT) ceramic material was prepared using a two-stage mechano-chemical activation technique. BMT substitution in Ca modified BaTiO3 resulted in substantial improvement in microstructural characteristics and energy storage performance compared to pure BCT. Introduction of BMT in BCT transformed it into relaxor ceramics, essential for high recoverable energy storage density and energy efficiency. The composition 0.65BCT-0.35BMT exhibited typical relaxor characteristics, large breakdown strength, and a significantly large dielectric constant, achieving an ultra-high recoverable energy density of 3.09 J cm(-3) with a moderately high energy efficiency of approximately 80.15%.

Summary: Efficient storage technology plays a crucial role in promoting the application of hydrogen as an energy storage medium. Among the solid-state hydrogen storage materials, magnesium-based materials are considered highly promising despite their drawbacks such as poor hydrogen absorption, desorption kinetics, and high operating temperature. Adding catalysts is an optimal approach to improving the kinetic performance of MgH2, and transition metal-based catalysts have shown excellent catalytic performance. This study mainly summarizes the impact of Co/Ni/Fe-based catalysts on the hydrogen storage performance of Mg and provides insights into future research perspectives.

Summary: We grew (Sr, Ca) Nd2Fe2O7 single crystals with the Ruddlesden-Popper structure using an optical floating-zone method. A significantly anisotropic magneto-dielectric effect (MD) was observed in a SrNd2Fe2O7 crystal at room temperature, with ab-plane and c-axial MD coefficients reaching -12.3% and -8.4% in a 1 T magnetic field. The anisotropic MD effect decreased with an increase in Ca concentration and eventually disappeared. The anisotropic MD effect in SrNd2Fe2O7 crystals can be attributed to polaronic hopping between neighboring Fe3+ ions through oxygen vacancies in an anisotropically antiferromagnetic matrix.

Summary: Facing the challenges of energy crisis and global warming, the development of renewable energy has received increasing attention. Metal-air batteries, such as Li-air battery and Zn-air battery, have shown great potential for energy storage due to their high specific capacity and environmental friendliness. However, the poor reaction kinetics and high overpotential during the charging-discharging process limit their wide application, which can be improved by the use of electrochemical catalysts and porous cathodes. Biomass, as a renewable resource, plays a critical role in the preparation of carbon-based catalysts and porous cathodes with excellent performance for metal-air batteries. This review highlights the latest progress in the preparation of porous cathodes from biomass for Li-air and Zn-air batteries and summarizes the effects of different biomass sources on cathode composition, morphology, and structure-activity relationship.

Summary: Efficient and environmentally friendly ferroelectric BSLNT ceramics were prepared and used as tribocatalysts for organic degradation. The catalytic capability was improved by enhancing the ferroelectric properties, leading to 92% RhB degradation after 2 hours. Further enhancement of the catalytic efficiency was achieved through electrical poling, reaching 96.8% degradation in 2 hours. Under the synergistic effect of illumination and friction, the degradation efficiency of RhB reached 95.2% after 30 minutes. This study demonstrates the application of highly efficient ferroelectric tribocatalysts for dye wastewater degradation, expanding the use of ferroelectric materials in catalysis.
