Summary: ZnO nanorods are grown along the c-axis using a sonicated sol-gel immersion method at a lower temperature, where the seed-layer precursor molarity and immersion time significantly impact the structural and morphological properties of the nanorods. These hexagonal nanorods exhibit green emission and persistent photoconductivity, which can be partially quenched through annealing. Annealing also helps improve transmittance and tunes the band gap value of bulk ZnO.

Summary: Hematite is a promising catalyst for photoelectrochemical water splitting due to its stability, abundance, and low cost. However, the slow water oxidation kinetics and poor charge transportation have limited its practical application. To address these issues, a three-component heterojunction photoelectrode was designed by incorporating a visible light responsive metal-organic framework (MOF) and optimized plasmonic Ag nanorods into hematite nanostructures. The incorporation of MOF and Ag nanorods resulted in improved light harvesting and enhanced charge transport, leading to superior performance for hematite-based photoelectrochemical water oxidation.

Summary: This paper aims to emphasize the impact of biochar addition on soil amendment and contaminants remediation during composting. Biochar improves composting performance and reduces contaminants. Co-composting with biochar has been shown to enhance soil biota and its abundance and diversity. However, it also has adverse effects on soil properties and microbe-to-plant interactions. Biochar co-composting promotes the remediation of heavy metals in contaminated soils and improves nutrient retention. It also has excellent adsorption capabilities for persistent and emerging pollutants. Additionally, this paper highlights future perspectives, research gaps, and recommendations for further studies.

Summary: Plasma-activated water (PAW), containing reactive oxygen and nitrogen species, has potential applications in food disinfection and sustainable agriculture. However, a lower-cost production system for commercial use is yet to be developed. Ultrasonic-activated water (UAW) offers a viable alternative, with similar properties to PAW but more feasible production. A novel double-bath-type sonoreactor efficiently produced UAW, with its composition and properties influenced by dissolved gases and acoustic density. The optimal gas composition was found to be a mixture of oxygen, nitrogen, and argon. The low-cost sonoreactor showed comparable H2O2 production efficiency to expensive sonoreactors and plasma devices.
