Summary: This study evaluated the use of electrodialysis for recovering cobalt, magnesium, manganese, and chromium ions from an acid multicomponent solution. Results showed successful extraction of Co2+, Mn2+, and Mg(2+) ions above 98%, while the extraction of Cr3+ reached only 83%. The differences in metal transport through the membranes were attributed to lower molar concentration, diffusion coefficient, and Stokes radius of chromium ions.

Summary: The perovskite structure materials used as an oxygen ion conductor in solid oxide fuel cells have been widely studied. In this study, a novel property of NaNbO3-based ceramics about oxygen ion conduction was reported. Bismuth doping significantly increased the grain size and enhanced the structural symmetry. Pure oxide ions conduction was achieved in Na0.4Bi0.2NbO3 composition. The electrical conductivity of Na0.4Bi0.2NbO3 increased by 3 orders of magnitude compared to that of NaNbO3 oxides, making it a potential candidate for the solid electrolyte of medium-temperature solid oxide fuel cells (IT-SOFCs).

Summary: This study successfully purified glutaric acid (GA) from the mixed dibasic acids (DBA) by using a coupled solution crystallization and melt crystallization method. The experimental results showed that GA had the highest solubility in the liquid phase and could be concentrated by cooling crystallization. The ternary solid-liquid melt equilibrium phase diagram based on the experimental data proved that the concentrated GA could be efficiently purified by melt crystallization after solvent evaporation. With the operated operating parameters, the purity of GA reached 99.06% by secondary melt crystallization.

Summary: This study demonstrates a simple and effective method to enhance the power conversion efficiency of highly efficient non-fullerene organic solar cells by mixing two electron transport materials. The new electron transport layer shows improved alignment with the active layer's energy level and morphology, leading to enhanced charge extraction, selectivity, and reduced exciton recombination. These improvements result in a boosted PCE in the PM6:Y6-based solar cells and also lead to leading results in binary all-polymer solar cells when combined with the non-halogenated solvent-processed PM6:PY-IT-based active layer.

Summary: This study investigates the multiscale behaviors of sapphire crystal growth along different crystal directions through theoretical and experimental studies. The results show that the growth behavior of sapphire along the c-axis is more complex compared to that along the a- and m-axes, involving solid-liquid and solid-solid transformations. Moreover, an abrupt change in the interfacial structure inhibits the transformation of liquid Al2O3 into α-Al2O3 along the c-axis.

Summary: Investigating the liquid structure of yttrium aluminum garnet (YAG) at high temperatures is significant for various fields, and molecular dynamic simulations were used to study the structure of YAG within a certain temperature range and to grow a YAG single crystal. The coordination number and bond length between cations and anions changed after melting, which can be explained by Pauling's third rule. In the liquid YAG, the coordination number decreased and the main structural units were AlO4 and YO7, which provided insight into phase selection and enabled rapid growth of YAG using the Czochralski method.
