“…They have attracted interest of many theoretical and experimental researchers probably because of their comparatively simple structure and very fascinating properties associated with a hydrogen bond system involving a large isotope effect, broad transparency range, a high-optical damage threshold and relatively low production cost [1][2][3][4][5]. Crystals with wide band gaps are transparent from the ultraviolet through the visible region.…”

“…In order to overcome the problem some dopants are added to suppress the effect of metal ion impurities on ADP and KDP crystals, for example EDTA or KCl reduces the effect of metal ion impurities and enhances the metastable zone width and increases the growth rate of the crystals [11]. In our earlier papers we have reported the growth of /1 0 0S directed ADP [12] and the effect of DL-malic acid [7], L-lysine monohydrochloride [4], oxalic acid [5], ammonium malate [13], Ni 2 + [14], Co 2 + [15], L-asparagine monohydrate [16] and ammonium chloride on ADP [17,18], in which the ammonium malate doped ADP crystals, show higher crystalline perfection and growth rate. Ammonium chloride doped ADP has high growth rate and SHG efficiency.…”

“…On the other hand, beyond the amino acids that are found in all forms of life, amino acids are also used in industry, with the production of bio degradable plastics, drugs and chiral catalysts being particularly important applications. At the same time, amino acids are used to modify the growth, structural, optical, thermal and dielectric properties of some crystallizing substances [10,11]. In another study, it has been shown that calcium oxalate aggregation on the heat exchanger is suppressed in the presence of amino acids [12].…”

The investigation on the mechanism of nucleation and growth of crystals at organic-inorganic interfaces is crucial for understanding biological and physiological calcification processes such as the formation of urinary stones. The effects of five different amino acids on the crystallization of calcium oxalate have been investigated at pH 4.5 and 37 °C in aqueous solutions in the batch type crystallizer. The products were characterized by Scanning Electron Microscopy (SEM), Fourier Transfer Infrared Spectroscopy (FT/IR) and X-Ray diffraction (XRD) analysis. Crystal size distribution (CSD) and filtration rate measurements were done. In order to determine the adsorption characteristics of amino acids on the calcium oxalate crystal surfaces, zeta potential measurements were also done and discussed. The results indicate that in the presence of all investigated amino acids, calcium oxalate monohydrate (COM) crystals were preferentially produced, but the crystal morphology varied with amino acid types and concentrations. Various crystal morphologies such as elongated hexagonal, coffin or platy habits were observed. In the presence of all investigated amino acids, the calcium oxalate crystallized in a monohydrate form. Electrostatic/ionic interaction, different adsorption properties and special functional effects of amino acids led to find different crystal morphology.

The crystallization of calcium lactate pentahydrate was performed in the absence and presence of the amino acids L‐methionine and D‐threonine. The metastable zone width was measured as a function of concentration of amino acids and cooling rate. Fourier transform infrared (FTIR) analysis, scanning electron microscopy (SEM), filtration rate, and average particle size measurements were performed. FTIR results showed that all crystals formed in calcium L‐lactate pentahydrate form, but crystals, which had a needle‐like crystal structure in pure media, experienced a habit change in the presence of amino acids. The average particle size and the length‐to‐width ratio of the crystals increased in the presence of amino acids which appeared as reduction in mean specific cake resistance. The amino acids exerted enlargement effects on the metastable zone width.
