Summary: In the leaching process of galena, the use of citrate ion as a complexing agent can achieve high dissolution rates in a relatively short period of time. The optimal complexing agent concentration for lead extraction shows the highest reaction rate at a pH of 8 and temperatures of 30 and 40 degrees Celsius.

Summary: This study demonstrates that the novel electrochemical catalyst improves the stability and electrochemical performance of R-PCCs. The enhanced stability and performance of the air electrode catalyst may be attributed to the higher electronegativity of La, which reduces basicity and improves chemical stability in acidic atmospheres; the smaller ionic radius of La, which alleviates lattice distortion; and the stronger interaction between La and lattice oxygen, inhibiting structural degradation caused by Sr segregation.

Summary: The paper focuses on the critical issue of cathode processing for metal-supported solid oxide fuel cell production. By using an ex situ sintering approach on Ni-Fe alloy supported SOFCs, LSM-BSCF cathodes were successfully fabricated and showed improved performance compared to in situ sintered cells. The study confirms the applicability and benefits of the novel ex situ sintering procedure for enhancing cell performance and durability.

Summary: This study presents a novel approach for the fabrication of ultrafine, multi-phase BSCF-based cathodes by combining modification and direct assembly methods. The ultrafine microstructure of the cathode powder is achieved through modification treatment and retained in the cathode without high-temperature sintering. The resulting ultrafine, multi-phase BSCF cell shows significantly higher peak power density, providing insights into the facile fabrication and application of efficient solid oxide fuel cells.

Summary: The BSCF+Co3O4 composite material is found to be a promising cathode for H-SOFCs, offering a solution to the thermal mismatch problem between the cathode and electrolyte. The addition of Co3O4 enhances the contact between the BSCF cathode and the electrolyte and also improves the catalytic activity of the cathode, resulting in significantly improved performance for H-SOFCs.

Summary: Boron isotope ratios in marine calcium carbonate can be used to study marine calcifier physiology and reconstruct past atmospheric CO2 levels. Understanding the pathways of boron incorporation into calcium carbonate is still incomplete, with experimental data suggesting that boron and sodium may substitute in pairs to achieve local charge balance. Interface electrostatics may drive variability in the concentration and isotopic composition of boron in synthetic CaCO3.

Summary: This study proposes a new strategy of Ce doping to enhance the stability and activity of BSCF fuel-cell cathode, and verifies its effectiveness through experiments. Ce doping can significantly increase the electrical conductivity of BSCF and reduce the polarization resistance, thereby improving the long-term stability of the cathode and the output performance of the cell.

Summary: Sodium citrate has been found to increase the negative charges on bitumen surfaces, leading to enhanced bitumen liberation and prevention of slime coating. Similar chemicals like EDTA and phosphate also increase the negative charges on bitumen surfaces, while sodium sulfate has the opposite effect. Ligands such as sodium citrate can remove metal ions from bitumen and adsorb onto the bitumen surface, modifying the zeta potential at the bitumen/water interface.

Summary: Increasing CO32- concentration in Na2HPO4 solution accelerates the fabrication rate of CO3Ap and results in changes in crystal shape and crystallite size. Higher CO32- concentration leads to more CO3 content in CO3Ap, larger pores, and altered pore distribution.
