Summary: Hard ferrite (CoFe2O4), soft ferrite (Ni0.8Zn0.2Fe2O4), and composite ferrite (CoFe2O4)x/(Ni0.8Zn0.2Fe2O4)1-x (hard/soft ferrite) with varying compositions were synthesized by sol-gel auto combustion method. X-Ray Diffraction analysis confirmed the formation of cubic structures in the samples. Thermal analysis using TGA/DSC determined the temperature of phase formation. FTIR spectroscopy data verified the successful synthesis and formation of functional groups in the ferrites. SEM characterization showed overlapping spherical particles, and elemental mapping was performed using EDS. FESEM and TEM analysis demonstrated enhanced magnetic hyperthermia properties. Vibrating Sample Magnetometry was used to study the saturation magnetization (Ms), coercivity (Hc), and remnant magnetization (Mr) of the samples. Zeta potential measurement examined the surface charge of the particles in DI water. Heating characteristics of the samples were evaluated in an alternating magnetic field. The magnetic properties depended on the concentration of soft and hard ferrite, and the magnetic heating efficiency depended on the sample composition.

Summary: FePS3, a layered magnetic van der Waals compound, exhibits a Mott insulator-metal transition under applied pressure, accompanied by changes in crystal symmetry and magnetic structure. To understand these transitions, it is essential to study the crystal structure as a function of pressure. Through single-crystal and powder x-ray diffraction measurements, we have confirmed that the highest-pressure transition involves a collapse of interplanar spacing and an increase in symmetry from monoclinic to trigonal space group, supporting one model over competing alternatives. Our findings provide crucial insights into the high-pressure behavior of these materials and demonstrate a comprehensive methodology for investigating complex two-dimensional material structures under pressure.

Summary: The study presents a highly efficient and selective photo-oxidation method for the direct conversion of methane to ethane using a Au nanoparticle (NP) loaded ZnO/TiO2 hybrid. This method achieves an ethane production rate of over 5,000 mu mol g(-1) h(-1) with 90% selectivity, which is more than an order of magnitude higher than current state-of-the-art photocatalytic systems. The enhanced photocatalytic activity is attributed to the formation of heterojunctions between ZnO and TiO2, while the Au cocatalyst facilitates C2H6 formation and inhibits overoxidation of CH4 to CO2.

Summary: Direct photocatalytic oxidation of methane to liquid oxygenated products at room temperature is achieved using atomically dispersed nickel anchored on a nitrogen-doped carbon/TiO2 composite (Ni-NC/TiO2) catalyst. The Ni-NC/TiO2 catalyst exhibits high activity and selectivity for the formation of Cl oxygenates, with a yield of 198 umol and a selectivity of 93% in 4 hours. The enhanced performance is attributed to the presence of single-atom Ni-NC sites that facilitate electron transfer and activate O2 to form reactive oxygen species.

Summary: The traditional process of synthetic nitrogen-fixing ammonia is energy-consuming and environmentally unfriendly. Therefore, exploring new methods for ammonia synthesis under mild conditions is crucial. Photocatalytic nitrogen fixation utilizes solar energy as an energy source to convert nitrogen to ammonia through photocatalysis at normal temperatures. In recent years, the development of highly efficient photocatalysts has been a hot topic. This study mainly discusses the structure and design of photocatalytic nitrogen-fixing materials, such as introducing vacancies, conducting element doping, and constructing heterojunctions. The study also introduces the oxidation process of N-2 to nitrogen compounds, providing inspiration for the research and development of nitrogen-fixing photocatalysts.

Summary: In this study, a composite electrode composed of Ti/TiH2/beta-PbO2_Mn3O4@C was fabricated and investigated for zinc electrowinning. The composite electrode exhibited low overpotential, Tafel slope, icorr, and high voltage stability, outperforming most reported Ti-based PbO2 electrode materials. The excellent catalytic activity can be attributed to the low resistance and porous interlayer of TiH2 nanosheets, as well as the addition of Mn3O4@C micro-flakes to the active layer.
