<p>CNTs and CuO will be used as electrocatalysts for redox reactions in rechargeable zinc-air batteries as the aim of this research. A carbon felt substrate was used to coat the CuO/CNTs composite, and the cathode properties were examined. Analyzed using XRD, FE-SEM, EDS, FT-IR, CV, and LSV. The results indicate that CuO/CNTs exhibits a monoclinic and hexagonal crystal structure, along with the presence of aromatic structures within the CNTs. The retention of PVDF was confirmed, and the composite demonstrated uniform dispersion on the carbon felt. The elemental composition was found to be C (54.52%), F (37.35% Cu (4.95%) and O (3.18%). At an applied voltage of 2 V, the current density increased from <br />0.66 to 6.92 mA cm^–2, while at 2.40 V, the current density decreased from -0.34 to -3.67 mA cm^–2. After 50 cycles, the current density declined by 5− 10%, indicating moderate electrochemical stability. The findings suggest that CuO/CNTs is a promising bifunctional electrocatalyst for both OER and ORR. Additionally, this research can be further developed into educational materials to enhance the understanding of zinc-air battery technology.</p>

<p>Bacterial wilt, caused by <em>Ralstonia pseudosolanacearum</em>, poses a serious threat to chili production. This study investigated the dual potential of <em>Streptomyces</em> sp. KKU215 as both a biocontrol agent against this pathogen and a plant growth-promoting bacterium for chili. The research involved <em>in vitro</em> antagonism assays, effects on chili seedling growth through seed priming, and effects in the biocontrol of bacterial wilt and growth promotion in pot experiments. <em>In vitro</em> assays confirmed that <em>Streptomyces</em> sp. KKU215 effectively inhibited <em>R. pseudosolanacearum</em> growth within 2 days, producing a clear zone with a diameter of 32.20 mm. Priming chili seeds with <em>Streptomyces</em> sp. KKU215 for 30 min significantly enhanced seedling growth 30 days after seeding, with increases in shoot length (14.21 vs. 12.25 cm), total length (21.05 vs. 18.63 cm), fresh weight (16.04 vs. 12.40 g), and dry weight (1.88 vs. 1.20 g), accompanied by a denser root system and larger leaves compared to the control. Most notably, in pot experiments, application of <em>Streptomyces </em>sp. KKU215 significantly suppressed bacterial wilt, achieving a disease severity reduction from 87.50% in the control to only 16.67% in the treated plants. <em>Streptomyces</em> sp. KKU215-treated seedlings showed enhanced growth, with enhanced growth, reaching maximum values for shoot length <br />(28.26 cm), root length (24.93 cm), fresh weight (7.56 g), and dry weight (0.89 g). These findings highlight <em>Streptomyces</em> sp. KKU215 is a highly promising dual-function agent for sustainable chili cultivation. Further validation in field trials and the development of a stable formulation are essential next steps for practical application.</p>
