“…The generation of optical harmonics, such as THG in crystals, has provided valuable information on the NLO characteristics of materials, particularly in determining the cubic susceptibility χ (3) . Third harmonic generation (THG) has several applications, including the production of high power laser sources and non-linear microscopy [114][115][116][117][118][119][120].…”

This review delves into the nonlinear optical characteristics of crystals derived from picric acid, providing a comprehensive analysis of their unique properties and potential applications in the realm of nonlinear optics. Picric acid, with its distinctive molecular structure, has been widely explored for its nonlinear optical behaviour, making it a fascinating subject for research and development. The review begins by elucidating the fundamental need and significance of crystal growth. The summary of preparation, spectral analysis and nonlinear optical characteristics and the significance of picric acid as a promising material in this domain is also discussed. The interpretation of nonlinear behaviour in optical properties of various compounds of picric acid is reviewed and discussed. The structural data of aminoacidic picrate crystals in the field of non-linear applications are reviewed. The conceptual background of nonlinear optical properties is well deliberated and used in order to have a better knowledge of the optical behaviour of the picrate crystals. UV-VIS spectroscopy and Second harmonic efficiency of picric acid compounds are also briefly discussed. In conclusion, this review provides a comprehensive overview of the nonlinear optical performance of picric acid-based crystals, offering valuable insights for researchers, scientists, and engineers working in the field of nonlinear optics.

“…Compound [A1 & A2] showed weak and moderate activity against the bacterial species used. Compounds [A3,A4 & A5] gave strong efficacy and high inhibition, reaching (5) cm at a concentration of (100) mg/ml and reached (4) cm at Concentration (50) mg/ml against all bacterial species used in the study [19][20][21][22][23]. Table (5), and scheme (2-5) demonstrate the effects of the inhibition zone diameter (IZD) in millimeters.…”

In this study, new Imidazolidin-4-one [A1-A5] compounds were prepared by the reaction of schiff base compounds with alanine in ethanol. The prepared compounds were characterized by physical properties, UV-Vis, FT-IR and 1H-NMR spectral and C.H.N analysis. TLC checked the purity for these compounds. All compounds [A1-A5] were prepared by the traditional method (reflux) and microwave technology. It was found that using the microwave method gives better results in terms of less time and, higher yield. Antibacterial behaviors were investigated against a variety of bacteria, including Escherichia coli and Klebsiella pneumonia Gram (-) ve, Staphylococcus aureus, and Staphylococcus epidermidis Gram (+) ve. The laser efficacy of the compounds [A1-A5] was evaluated after they were radiated by laser for (10, 20, 30) seconds. As the melting point and color of the substances were determined, it was discovered that they were unaffected and did not disintegrate or polymerize. Using the Chem Draw Specialist 19.0 program, the stereoisomers of the prepared compounds [A1-A5] were examined at the lowest layer stage. Using the Chem3D 19.0 program, the heat of the formulation of the compounds [A1-A5] was also investigated.
