Summary: Cr-doped Na3V2(PO4)2F3/C material was synthesized and its effects on structure, morphology, and electrochemical performance were investigated. The optimized material Na3V2-xCrx(PO4)2F3/C (x = 0.05) exhibited high initial discharge capacity of 101.9 mAh g-1 at 10 C and retained 68.7% of its capacity after 1000 cycles. The improved performance was attributed to higher crystallinity, improved intrinsic conductivity, and enhanced sodium ion diffusion coefficient due to the doped Cr3+.

Summary: Ni, Zn, and Co-doped Ti/SnO2-Sb anodes were prepared using an unconventional sol-gel method and used for phenol electrochemical degradation. Among them, Ti/SnO2-Sb-Co showed the longest service life (213.9 h), lowest energy consumption, and promising practical application potential, despite a slightly lower phenol degradation rate compared to Ti/SnO2-Sb-Ni and Ti/SnO2-Sb-Zn.

Summary: Extensive use of carbon-based materials has revolutionised modern scientific areas such as transportation, electronics, material chemistry, and electrochemical energy storage due to their outstanding characteristics. High purity carbon aerogels, prepared using synthetic chemistry techniques, offer superior conductivity, high porosity, and chemical inertness, making them a potential substitute for naturally occurring carbonaceous materials. Designing tailored polymeric carbon materials according to anticipated uses through altering synthesis parameters can fine-tune porous structures and facilitate composite material production.

Summary: In this study, sol-gel derived lithium-doped zinc oxide (LZO) film is used as an electron transport layer (ETL) for inverted red quantum dot light-emitting diodes (QLED) to achieve low-cost and high-efficiency QLED. Lithium doping can tune the conduction band minimum, density of oxygen defects, and conductivity of zinc oxide, resulting in significantly improved external quantum efficiency (EQE) and current efficiency of the QLED device.

Summary: Neodymium-ion doping has been found to have an effect on the crystalline microstructure, crystal appearance, and electrochemical parameters of LiMnPO4/C cathodes. Proper neodymium-ion doping can enhance lithium-ion diffusivity and improve the high-rate performance of the cathode materials, as demonstrated by the LiMn0.94Nd0.06PO4/C sample.

Summary: The Sb-doped SnO2-SiO2 film shows reduced crystallinity with Sb doping, exhibiting M-shaped changes in lattice parameters with increasing Sb concentration. Nanoparticle size decreases and then increases with Sb doping levels above 6 mol%. Additionally, the transmittance of the glass substrate coated with this film decreases, while resistance and dust removal performance exhibit complex changes with varying Sb concentrations. At 12 mol% Sb doping, the film exhibits minimal resistance and a 64% dust removal performance.

Summary: A series of Yb3+- and Er3+-doped Ca3Sc2Si3O12 (CSS) upconversion (UC) phosphors were synthesized by the sol-gel combustion method to develop novel luminescent materials for optical temperature measurement. The addition of Yb3+ greatly enhanced the emission of Er3+ by effective energy transfer. The prepared CSS:Yb3+,Er3+ phosphors exhibited green and red emissions corresponding to specific transitions of Er3+, and showed excellent temperature-dependent behavior with high sensitivity.

Summary: Zn-doped cobalt perovskites Co1-xZn1.5xFeO3 nanoparticles were synthesized using auto-combustion sol-gel approach. The effects of Zn doping on structural, morphological, dielectric, electrochemical, and photocatalytic properties were investigated. Zn doping significantly influenced the dielectric properties, AC conductivity, specific capacitance, and band gap energy of Co1-xZn1.5xFeO3. The photocatalytic activity of Co1-xZn1.5xFeO3, enhanced by Zn doping, showed promise for applications such as dye degradation under solar light irradiation.
