Summary: Oxidative stress is a major contributor to various adverse conditions, and novel metal-doped graphene quantum dots (GQDs) show promising potential as radical scavengers. We synthesized different biocompatible GQDs with metal dopants and evaluated their radical scavenging abilities for the first time. Metal-doped GQDs consistently exhibited higher antioxidant properties than undoped GQDs, with aluminum-doped GQDs showing the highest radical scavenging ability. Tm-doped GQDs matched the antioxidant properties of ascorbic acid in one assay. These doped GQDs not only possess fluorescence imaging capabilities but also have potential as multimodal therapeutics for cancer treatment.

Summary: This study evaluated the effect of fertilization techniques and grafting on polyphenol oxidase (PPO) activity and colorimetric parameters in cultivated eggplants. Fertilization alone significantly increased PPO activity, while fertilization combined with grafting decreased PPO activity. There was a significant positive correlation between PPO activity and the a* values of the eggplants. Additionally, eggplant slices exposed to room temperature for 60 minutes showed a significant increase in PPO activity and color parameters.

Summary: Oxygen is essential for aerobic organisms, generating ROS during electron transport reactions. Recent studies have shown ROS play a crucial role in plant growth and stress response, with extremophytes adapting to adverse environments by minimizing ROS generation. High-altitude extremophytes, especially from the Himalayas, exhibit unique mechanisms for managing ROS, which could potentially be applied to engineer stress resilience in other plants.

Summary: We investigated the electromigration forces for weakly bonded adsorbates on graphene using density-functional based calculations. The results showed that the nature of electromigration forces depends critically on the energy level alignment between the adsorbate state and the Fermi level of the graphene. For resonant adsorbates, the electromigration force is dominated by the electron wind force, while for nonresonant adsorbates, it is essentially the direct force dependent on the adsorbate charge. Moreover, we demonstrated that the magnitude of electromigration forces can be continuously adjusted through electrostatic gating for resonant adsorbates.

Summary: In this study, a facile method was developed to obtain heavy-metal-free electrode materials with effective catalytic activity in the oxygen reduction reaction (ORR). Nitrogen-doped graphene foams prepared at higher carbonization temperatures showed increased catalytic activity in ORR due to the presence of more active sites. The research highlights the importance of nitrogen content and carbonization temperature in improving the catalytic activity of electrode materials for ORR.

Summary: This study evaluated the applications of drench (D) and foliar (F) ZnO nanoparticles (NZnO) compared to ionic Zn2+ (ZnSO4) in lettuce. Results showed that NZnO promoted increases in biomass (14-52%), chlorophylls (32-69%), and antioxidant compounds such as phenolics, flavonoids, and vitamin C compared to Zn2+. A better response was found in the plants with foliar applications of NZnO equivalent to 50-75% of the total Zn2+ applied conventionally. These findings demonstrate the potential of NZnO in improving fertilizer efficiency and the quality of lettuce.

Summary: The tomato crop is vulnerable to different types of stress, including the phytopathogen Fusarium oxysporum f. sp. lycopersici. Graphene-Cu nanocomposites have shown positive effects on tomato plants infected with Fusarium oxysporum, including delaying the incidence of vascular wilt disease, increasing photosynthetic pigments, and improving the antioxidant defense system. Furthermore, graphene functionalization enhances the effectiveness of the nanocomposites. The plants treated with the Graphene-Cu nanocomposite exhibited better responses to biotic stress in terms of water potential and the efficiency of photosystem II.

Summary: Blueberry is a popular fruit with high demand and consumption due to its bioactive compounds and high antioxidant capacity. The application of glutamic acid (GLU) and 6-benzylaminopurine (6-BAP) as biostimulants positively influenced flower bud sprouting, fruit quality, and antioxidant content in blueberries. Specifically, 500 mg L-1 GLU and 10 mg L-1 6-BAP increased flower bud number, while 500 mg L-1 GLU and 20 mg L-1 6-BAP resulted in fruits with higher flavonoid, vitamin C, and anthocyanin content, as well as enhanced activity of catalase and ascorbate peroxidase enzymes. Therefore, the application of these biostimulants effectively enhances the yield and quality of blueberries.

Summary: The hypothesis of this trial is that the concentration of ions measured in the soil solution allows evaluating the efficiency of the nutritional management and its effect on the tomato crop. The experiment aimed to measure the effect of continuous application of four nutrient solution concentrations on the concentration of ions in the soil solution and the response of the tomato crop. The results showed that the concentration of the nutrient solution has a direct relationship with the availability of nutrients, and the concentration of 125% showed the best effect.
