“…These results of enhancing leaf nutrient contents may be due to that Zn is essential for sugar regulation and enzymes that control plant growth [38]. The obtained results are in conformity with those of El-Khayat [39], (Gomaa [40] on Antholyza aethiopica, Yadav [41] on tuberose and Samia and Mahmoud [42] on Tritonia crocata.…”

This study was conducted to evaluate the effectiveness of zinc nanofertilizer strategy on sweet basil yield, through alone application or combined with pre-sowing laser irradiation. Furthermore, evaluate the growth of plant and the level of active essential oil constituents. Zinc oxide (ZnO) nanoparticles (NPs) were synthesized, and transmission electron microscope revealed particle size of approximately 10.5-15.5 nm. ZnO NPs were applied to sweet basil plants by foliar spray at varying concentrations (10, 20 and 30 mg/L); He Ne laser of power 3mW was used for red light irradiation of sweet basil seeds for 2 min. exposure time. Total chlorophyll, total carbohydrate, essential oil levels, zinc content, plant height, branches/plant and fresh weight were measured. In general, the combined foliar spray application of ZnO nanofertilizer with pre-sowing He Ne laser irradiation showed more effectiveness than ZnO nanofertilizer alone and 20mg/L concentration gave the highest results of all measured traits. Statistical analysis (t-test) showed significant differences among the effects of the various concentrations of zinc oxide NPs on these attributes. The results showed an inverse relationship between the total carbohydrate content and the percentage of essential oil in the leaves. Together these findings support the usefulness and effectiveness of zinc oxide nanofertilizer and laser irradiation treatment to enhance the growth and yield of sweet basil plants. The article presents some promising patents on ZnO nanofertilizer and He Ne laser irradiation.

“…The agreement between the DFT values and the experimental data is excellent. 22,23 The relative energies of various phases of AlN per formula unit are also listed. From Table I, it is shown that the wurtzite phase is most energetically stable, while the zincblende phase is 43 meV higher than the wurtzite phase, and the rocksalt phase is 345 meV higher.…”

An unusual growth mechanism of metastable zincblende AlN thin film by diffusion of nitrogen atoms into Al lattice is established. Using first-principles density functional theory, we studied the possibility of thermodynamic stability of AlN as a zincblende phase due to epitaxial strains and interface effect, which fails to explain the formation of zincblende AlN. We then compared the formation energetics of rocksalt and zincblende AlN in fcc Al through direct diffusion of nitrogen atoms to Al octahedral and tetrahedral interstitials. The formation of zincblende AlN thin film is determined to be a kinetically driven process, not a thermodynamically driven process.

“…1(b) that there is a slightly decrease in lattice parameters as we increase the Zn content whose values are given in the table 1. The most probable reason for such a behavior of the nanomaterial is understood due to the smaller atomic radii of Zn 2+ ion (0.74 Å) as compared to the Cd 2+ ion (0.97 Å) and Zn 2+ ion replace the Cd 2+ ion , therefore lattice is contracted 18,19 . Furthermore, the Lorentz factor has also been calculated which depends on the Bragg angle/diffraction geometry and gives the distribution of diffraction planes in the powder samples.…”

A desirable quality of copper and manganese codoped Cd 1-x Zn x S (x≤1) quantum dots have been synthesized successfully using chemical co-precipitation method at room temperature. Structural investigations of the synthesized samples were carried out by powder XRD, TEM FTIR and AFM techniques. Further, the XRD results confirm that Cu and Mn codoped Cd 1-x Zn x S nanocrystallites exhibit wurtzite structure. Lattice strain and average nanocrystallite size in the range 2-4 nm have been determined. The FTIR analysis identifies absorption peaks of Cd-S/Zn-S stretching modes along with presence of some moisture content in the synthesized samples. The TEM analysis further confirms polycrystalline nature of Cu, Mn doped Cd 1-x Zn x S (x≤1) nanocrstallites by SAED pattern and corresponding histograms give the particle size distribution.
