“…BAP salt was synthesized by taking AR-grade β-alanine and picric acid in the equimolar ratio. Then, the calculated amounts of reactants were dissolved in double distilled water and stirred well using a magnetic stirrer for about 2 h. The solution was heated at 70 °C until the synthesized salt of BAP was obtained [20]. The obtained salt was re-crystallized twice to improve the purity of the synthesized salt.…”

“…The metal derivatives of picric acid are helpful in homeopathy medicine and it shows extraordinary variety in the bonding of metal salts and complexes [17]. Many researchers have reported on the growth and studies of various picrate-type crystals in the literature [18][19][20][21]. In this work, β-alanine is combined with picric acid to form a beta-alaninium picrate (BAP) crystal and, as no work is available in the literature on the detailed studies of metastable zone width (MSZW), nucleation kinetics, growth, and various studies of BAP crystal, the aim of the work is to report the results obtained from solubility, MSZW, critical parameters, XRD studies, spectral studies, and second harmonic generation (SHG) studies.…”

Beta-alaninium picrate (BAP) salt has been synthesized and the solubility of the synthesized sample in double distilled water was determined at different temperatures. Solution stability was studied by observing the metastable zone width by employing the polythermal method. Induction period values for different supersaturation ratios at room temperature were determined based on the isothermal method. The nucleation parameters such as critical radius, critical free energy change, interfacial tension, and nucleation rate have been estimated for BAP salt on the basis of the classical nucleation theory. The lattice parameters of the grown BAP crystal were determined using the x-ray diffraction (XRD) technique. The reflection planes of the sample were confirmed by the powder XRD study and diffraction peaks were indexed. Fourier transform infrared spectroscopy and Fourier transform-Raman studies were used to confirm the presence of various functional groups in the BAP crystal. The nonlinear optical property of the grown crystal was studied using the Kurtz-Perry powder technique. UV-visible spectral studies were carried out to understand optical transparency and the type of band gap of the grown BAP crystal.

“…In the IR and Raman spectra of (I) and (II) below 1700 cm -1 the strong absorption bands and intensive Raman lines are caused mainly by picrate anions. Similar pattern is observed also in the spectra of glycine glycinium picrate [3], L-alanine L-alaninium picrate monohydrate [5], β-alaninium picrate [28] and L-methioninium picrate [29]. In the Raman spectra the most intensive lines are characteristic for nitro groups.…”

“…Picric acid is a highly oxidative, yellow crystalline solid, soluble in water, alcohol, chloroform, most organic solvents, and ether and the presence of three electron withdrawing nitro groups in the picric acid makes it as a good acceptor for neutral carrier donor molecule [14,15]. Picric acid has been combined with other amino acids to form various complexes and various studies on picrate-type crystals have been reported by many researchers [16][17][18][19][20]. Picric acid is an interesting inorganic matrix modifier due to its large dipole moment and its ability to form an extensive network of hydrogen bonds.…”

Potassium dihydrogen phosphate (KDP) crystal has been doped with picric acid to alter its physical and chemical properties. Picric acid doped KDP salt was synthesized by adding 2 mole% of picric acid into the aqueous solution of KDP. Using the synthesized salt of picric acid doped KDP and double distilled water, single crystals were grown by solution method with slow evaporation technique. The grown single crystal was subjected to XRD method to find the crystal structure. The functional groups of the sample were found by FTIR method. The elements in the picric acid doped KDP crystal were identified by EDAX and CHN analyses. SHG studies of the sample were done to check the second order NLO property. Dielectric studies for picric acid doped KDP crystal were carried out using a multi-frequency LCR meter. Thermal stability of the sample was found by TG/DTA studies. The microhardness of the sample was also measured at different applied low loads and the results obtained from the various studies are discussed.
