ZnO nanofertilizer and He Ne laser irradiation for promoting growth and yield of sweet basil plant.

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.

Influence of solvent polarity and medium acidity on the UV-Vis spectral behavior of 1-methyl-4-[4-amino-styryl] pyridinum iodide.

Electronic absorption, and excitation spectra of 1-methyl-4-[4-aminostyryl] pyridinum iodide (M-NH2) were measured in solvents of different polarity. The (M-NH2) dye exhibits negative solvatochromism, i.e.
