“…The crystal parameters and cell volume were found to be well in agreement with reported values [10] as shown in table (1).From the grown doped crystal lattice parameters and space group it is clear that the basic structural property and space group of KDP is not altered by the dopant [11]. …”

Abstract-Potassium dihydrogen phosphate is a material rich in NLO property with wide range of industrial applications. Certain Amino acids are also rich in NLO properties so they are used as dopants.In the present work LSerine a non essential amino acid is added in the ratio 1:1 molar percentage to KDP. Single crystals were grown by slow evaporation method. The grown crystals were characterized by powder X-ray diffraction, Single crystal X-Ray diffraction, UVvis-spectroscopy, Fourier transform infrared spectroscopy (FTIR), SHG efficiency and dielectric studies, The single crystal X-ray diffraction studies reveal the structure and space group of the crystal. The powder X-ray diffraction study shows that the crystalline perfection of grown crystal is good. Fourier transform infrared studies confirm the functional groups of the crystals. It is seen from UV-vis studies that the optical transparency is found to increase much by adding chlorides. SHG efficiency of KDP is found to be slightly increasing with doping of L-Serine.The electrical properties of the crystal have been studied using dielectric constant studies. All the results are compared with the results of pure KDP.

We investigated different combinations of polymers (5% each) (i) starch, gelatin (polymer coating; PC-1), (ii) polyvinyl alcohol (PVA), gum Arabica (PC-2), (iii) PVA, gelatin (PC-3), (iv) starch, gum Arabica (PC-4), (v) gelatin, gum Arabica (PC-5), (vi) starch, PVA (PC-6), for coating NPK (17, 17:17) in a fluidized bed granulator. Morphological characterization indicated a uniform coating of all formulations on NPK granules. A slow release of N (PC-3), P (PC-6), and K (PC-3) was observed in water. In soil, high mineral N (63%), plantavailable P (72%), and K (24%) were observed in PC-3, PC-5, and PC-6, respectively than uncoated fertilizer. Microbial biomass NPK was also higher in these treatment. This resulted in higher maize yield (66%), N (114%), P (164%), and K (137%) uptakes and apparent N (267%), P (196%), and K (358%) recoveries from applied fertilizer in these treatments. Among these, PC-3 resulted in an increase of 115% shoot N, 169% P and 138% K uptakes and 268% apparent N, 206% P and 361% K recoveries than uncoated fertilizer. Hence, coating of NPK with this biodegradable polymer combination controlled N, P, and K release and synchronized these nutrients availabilities with maize nutrients demand therefore resulted in higher maize crop yield and nutrient utilization efficiencies.

“…The use of special additives is an effective way to enhance metastable zone width and then accelerate the growth rate 18 . Recently, attempts have been increasing to modify the crystal properties by adding metallic [19][20][21] , inorganic 22,23 and organic [24][25][26][27][28] dopants and by mixing different compounds in different proportions 29,30 .…”

Low temperature solution growth technique is a versatile and low cost technique to grow single crystals of good quality. Before crystal growth, it needs to decide solvent and growth temperature by studying solubility at different temperatures in different solvents, and pH of the growth solution. Metastable zone width and induction period are other important parameters considered during crystal growth. We have presented a simple, cost effective test to decide growth temperature, solution pH and proportion of different components (in case of multi-component compounds) of compound in the solution to grow quality single crystals with optimum growth rate. L-arginine phosphate monohydrate is a promising nonlinear optical crystal and we have successfully attempted to study the optimum pH and proportion of L-arginine and phosphoric acid in the solution for crystal growth by measuring ultrasonic velocity and determining related thermodynamic parameters.
