“…Nevertheless, these positive values can be also attributed to a stabilizing process where other compounds derived from glucose could be produced, such as bio-oils. 58,59 In this approach, it was observed that between 250 °C and 440 °C the glucose pyrolysis was not finished, and then as the positive values did not continuously increase, some bio-oils were also undergoing several decomposition processes, increasing the production of gas. 60 In contrast, from 440 °C to 600 °C, most of the pyrolysis decomposition occurred, implying that bio-oil may be thermally stable in that temperature range.…”

“…Control plants were also grown without the addition of nanoparticles. The synthesis and characterization of the nanoparticles used in this study were reported in the previous papers [ 54 , 55 , 56 ]. The plants were grown in the phytotron, at a humidity of 60%, with a day-night cycle of 16 h light and 8 h dark, at a temperature of 20 °C/18 °C day/night.…”

The aim of this work was to evaluate the effect of six nanomaterials, namely CNT-COOH, CNT-MnO2, CNT-Fe3O4, CNT-MnO2-Fe3O4, MnO2, and Fe3O4 on lettuceTo determine the impact of nanomaterials on lettuce, the results obtained were compared with those for the control plant, grown in the same conditions of light, temperature, and humidity but without the addition of nanomaterial. The study found that the content of bioactive compounds and the antioxidant capacity varied in the treated plants compared to the control ones, depending on the nanomaterial. The use of CNTs functionalized with metal oxides increases the elemental concentration of lettuce leaves for the majority of the elements. On the contrary, metal oxide nanoparticles and CNT functionalized with carboxyl groups induce a decrease in the concentration of many elements. Soil amending with MnO2 affects the content of more than ten elements in leaves. Simultaneous application of CNT and MnO2 stimulates the elemental translocation of all elements from roots to leaves, but the simultaneous use of CNT and Fe3O4 leads to the most intense translocation compared to the control other than Mo.

The sustainable and environmentally benign biogenic synthesis of manganese‐oxide nanoparticles (MnO2 NPs) in a single crystalline δ‐phase and its subsequent synthetic utility have been described. The synthesized δ‐MnO2 NPs were characterized using scanning electron microscopy (SEM), energy dispersive X‐ray (EDX), and X‐ray diffraction (XRD) analysis techniques. The detailed analysis envisages the reduction of Mn(VII) to Mn(IV) was facilitated by various phytochemicals present in the aq. mango leaves extract, avoiding the use of external ligand source. The synthesized δ‐MnO2 NPs were perceived in a single delta (δ) monoclinic crystalline phase, wherein a spherical agglomerated morphology was displayed with a particle size of <5 nm. Further, the utility of newly developed δ‐MnO2 NPs was showcased for alpha‐keto‐alkylation and quinoline synthesis via hydrogen autotransfer and the acceptorless dehydrogenative coupling strategy. Moreover, a series of control experiments, mechanistic elucidation, catalyst recyclability, and a dye removal study were demonstrated.
