Summary: In this study, Aurivillius Bi5Ti3FeO15 ceramic was synthesized using a solid-state reaction route, confirmed to be a single phase without impurities. The research found that the resistance and capacitance of grain boundaries were more prominent than those of grains, and the conduction process was dominated by the hopping mechanism. Additionally, the activation energies of relaxation and conduction processes were very similar, suggesting the involvement of the same type of charge carriers in both processes.

Summary: This study tested the water content of a porous geopolymer using impedance methods. The pores of the material were filled with distilled water, and the water content, porosity, and specific heat were analyzed using differential scanning calorimetry (DSC) and mercury porosimeter. Impedance tests were conducted to develop a quick method for assessing the water content, showing significant differences in impedance measurements as the material dried out. A simple method for assessing the water content of the geopolymer was proposed, using Nyquist graphs to visualize changes in impedance values.

Summary: The Sn-doped Pb(Zr0.52Ti0.48)(1-x)SnxO3 samples were prepared by conventional solid-state reaction method, and Raman spectroscopy confirmed the tetragonal structure. Impedance spectroscopic studies indicated a non-Debye relaxation process, with Cole-Cole plots showing the contribution of grain and grain boundary to the conduction process. The values of activation energy suggested that the conduction is ionic in nature, while AC conductivity followed Johnscher's power law. Ferroelectric studies demonstrated that the remnant polarization (P-r) increased with Sn substitution.

Summary: This study investigates the effect of strontium (Sr) concentration on the ultrafast humidity sensing performance of Sr doped zinc oxide (SrxZn1-xO) nanostructured thin films. The films were synthesized using the sol gel method with varying Sr concentrations. The results showed that the SrxZn1-xO films had a hexagonal wurtzite structure, and the preferential orientation changed with Sr doping. The films exhibited high sensitivity, stability, and fast response and recovery times, with Sr0.10Zn0.90O being the best sample in terms of humidity sensitivity and response and recovery times. This study highlights the potential of SrxZn1-xO nanostructured thin films for high-performance humidity sensor applications.

Summary: LiNixCoyMn1-x-yO2 (NCM) is a critical cathode material for lithium-ion batteries in electric vehicles. The aging of cathode/electrolyte interfaces leads to capacity degradation and long-term cycle instability. A novel neural network model called ACGNet is developed to predict electrochemical stability windows of crystals, allowing for high-throughput screening of coating materials. LiPO3 is identified as a promising coating material with high oxidation voltage and low cost, which significantly improves the cycle stability of NCM batteries. This study demonstrates the accuracy and potential of machine learning in battery materials.
