“…This could be predictable to number of icons in the nanoparticles superficial fustily increases as crystal sizes decreases. Hence, the nanoparticles with a small crystal size can characterize the highest luminescence intensity related to the biggest crystal solid [24][25][26][27][28][29]. This could be predictable to number of ions in the nanoparticles superficial fustily increases as crystal size declines.…”

A green deposition method of zinc oxide nanoparticles using coffee leaf extraction was successfully prepared. The use of these preparation techniques is accepted by many researchers because it is nonexpensive and simple and has no environmental impact during the operation. The determination and reduction of Zn ions to ZnO NPs were characterized by using a UV-visible spectroscope. The UV-visible spectroscopy result reveals that the large band gap energy is observed in the visible region at the wavelength of 300 nm. X-ray diffraction and SEM analysis confirm that the deposited nanoparticle is highly crystalline with (111), (222), and (100) planes and cubic shape structure. The coffee leaf extraction serves as a reducing agent for stability of the particle length, where its medicinal value outcome showed an important antibacteria of the pathogenic type which appeared on the wound. The present research deals with the green synthesis of ZnO NPs as well as its application in toxicity reduction.

The translucent and nano-crystalline PbS films were equipped with the CBD techniques on metal substrates by the temperature of 90 °C through aqueous solutions of Lead Nitrate and Thiourea. The XRD phases verify the crystalline property of synthesized thin films that the shape falls in the cubic structures with favourite orientations. It revealed that the prepared material is cubic crystal oriented as (111), (110), (100) and (101) crystal planes. The crystalline size varied between 0.4 and 0.7 nm. The band gap was assessed using UV–vis captivation spectra and Tau relations. The average energy band gap was found to be 2.43 eV which is greater than bulk materials of PbS; because of quantum confinements of Lead Sulfide Nano Crystalline thin films, and PL also confirms this result. The variation in band gap with Leaf extracts and particle sizes displayed blue shifts characteristic of electrons quantum confinements. SEM micrograph shows extremely uniform and adherent PbS films are found at higher PH values. It was evidently observed that the viscosity of the synthesized thin films reduced from 563 to 111 nm with a rise in pH value. The sample prepared at pH 4 shows good performance, and thin films deposited from Avocado (Glycosmis cochinchinensis) leaf extracts are a promising method to empower pollution remediation and future energy.

“…Amino acids are essential metabolites in plant primary metabolism and play an important role in plant physiological processes: acting as osmolytes, modulating stomatal opening, and serving as precursors for the synthesis of defense-related metabolites and signaling metabolites [38]. An enormous variety of secondary metabolites are derived from their chemical structures, many of which have important defense mechanisms [39].…”

Background Mechanical damage is an unavoidable threat to the growth and survival of plants. Although a wound to senescing (lower) leaves improves plant vitality, a wound to younger (upper) leaves often causes damage to or death of the whole plant. Source-sink models are often used to explain how plants respond to biotic or abiotic stresses. In this study, a source-sink model was used to explain the difference in the metabolic mechanism of mechanical damage to young and senescing leaves of Catharanthus roseus. Results In our study, GC-MS and LC-QTOF-MS metabolomics techniques were used to explore the differences in source-sink allocation and metabolic regulation in different organs of Catharanthus roseus after mechanical damage to the upper/lower leaves (WUL/WLL). Compared with that of the control group, the energy supplies of the WUL and WLL groups were increased and delivered to the secondary metabolic pathway through the TCA cycle. The two treatment groups adopted different secondary metabolic response strategies. The WLL group increased the input to the defense response after damage by increasing the accumulation of phenolics. A source-sink model was applied to the defensive responses to local (damaged leaves) and systemic (whole plant) damage. In the WUL group, the number of sinks increased due to damage to young leaves, and the tolerance response was emphasized. Conclusion The accumulation of primary and secondary metabolites was significantly different between the two mechanical damage treatments. Catharanthus roseus uses different trade-offs between tolerance (repair) and defense to respond to mechanical damage. Repairing damage and chemical defenses are thought to be more energetically expensive than growth development, confirming the trade-offs and allocation of resources seen in this source-sink model.
