Summary: An efficient and facile method for synthesizing BiVO4/reduced graphene oxide (BiVO4/rGO) photocatalyst via a one-pot hydrothermal process was developed. Ethylene diamine tetraacetic acid disodium salt (EDTA-2Na) was used instead of nitrate to provide an acidic environment, preventing the hydrolysis of Bi3+ and increasing the safety of the process. Loading BiVO4 on rGO significantly enhanced the photocatalytic activities, with a degradation efficiency of Rhodamine B (rhB) reaching 98.3% in 180 minutes. This work provided an ideal method for stable, efficient, and recyclable photocatalysts suitable for the visible light range.

Summary: Bio-coke is a solid biofuel that can replace coal and coal coke. By studying the effects of biomass type and production conditions on combustion characteristics, it was found that the combustion time of bio-coke can be predicted using a shape factor and is not affected by aspect ratio. Additionally, Japanese cedar bio-coke has a 2.5 times faster flaming combustion rate compared to green tea bio-coke.

Summary: In this study, numerical models based on experimental results were used to investigate the changing rules of maximum fragment velocity under different aspect ratios in hollow charges. The differences between driving behaviors under different detonations were also discovered. Formulae for maximum fragment velocity under end and central line or hollow surface detonations were established for the first time and their accuracy was verified through experiments. This study provides valuable references for optimal design and damage assessment of ammunition, as well as for the design of protection structures.

Summary: Reduced graphene oxide layered TiO2 was utilized as a dark cathode for CO2 reduction reaction, with BiVO4 photoanode. The selectivity of liquid fuel production was achieved by adjusting the reduction degree of the rGO layer on TiO2 electrode, controlling the free energy level of electrons involved in CO2RR. The mechanism and pathway of liquid product selectivity were suggested based on isotope labelling and in-situ electron paramagnetic resonance spectroscopy studies.

Summary: La(OH)(3) nanorods with different aspect ratios were successfully synthesized using a simple hydrothermal method without surfactant, catalyst, or template. Controlling the alkali source amount and reaction time is crucial for morphology and size of the La(OH)(3) products. The La2O3 nanorods obtained from La(OH)(3) samples show characteristic emissions when doped with lanthanide ions, indicating potential applications in lighting, optical displays, and optoelectronic devices.

Summary: In this study, n-Type ZnO nanorods were successfully grown on a p-type Si substrate using the hydrothermal technique, and ZnO-based UV photodiodes were fabricated. The structural properties of the ZnO nanorod arrays were found to be influenced by the solution volume in the hydrothermal process, with well-aligned arrays observed on all substrates. Increasing the growth solution volume resulted in higher responsivity of the ZnO-based photodiodes, and the optical properties of the samples were also affected by this volume change.

Summary: This study investigates the hydrodynamic characteristics of an elastically-mounted elliptic cylinder at low mass and damping ratios. The results show that the streamlined profile of the cylinder delays vortex shedding and reduces vorticity. However, the hydrodynamic characteristics become more complicated for larger aspect ratios.

Summary: In this study, iron oxide nanorods were prepared by using b-FeOOH nanorods as a template, and the influence of their size on the properties of magnetorheological (MR) fluids was evaluated. The results showed that the size of the nanorods affected the shear stress of the MR fluids, and MR fluids prepared with larger nanorods exhibited higher magnetic saturation and shear stress. Therefore, gaining control over the size and aspect ratio of magnetic particles can improve the performance of MR fluids.

Summary: This study investigates forced convection heat transfer around wavy elliptic cylinders with different aspect ratios and wavelengths. The results show that short wavelengths result in quasi-2D thermal structures, while long wavelengths form 3D thermal structures. The thermal characteristics are influenced by the state of the thermal structures. As the aspect ratio decreases, the streamlined shape becomes predominant in stabilizing forced convection.
