By the most widely used slow evaporation technique at room temperature, L-Threoninum Cobalt (II) Sulfate Heptahydrate (LTCS) materials were grown for various applications. The structure of orthorhombic LTCS was identified by X-Ray Diffraction studies (Powder X-Ray Diffraction and Single crystal X-Ray Diffraction), this analysis has also reported the crystallinity, cell parameters (a = 5.35, b = 7.93, c = 13.71), and space group (non-centrosymmetric) of the grown material. Functional groups were affirmed by FTIR analysis. Optical analysis straightforwardly confirms LTCS crystals has greater optical transparency, and Eg = 5.6 eV demonstrates the appropriateness of prepared crystals to optical applications. The mechanical properties were validated with the aid of Vickers' microhardness measurement and that also suggests LTCS belongs to the class of hard material. In this respect, the SHG efficiency of the LTCS crystal grown is 1.25 times greater than that of the KDP crystal because Co+ ions boost the SHG efficiency of LTCS and it was tested by Kurtz and Perry's technique. Electrical results documented the good conducting properties of LTCS crystal. The LTCS substance used to treat fungal and bacterial infections and this bacterial and fungal destroying property was validated by an antimicrobial assay.

“…Cobalt compounds are efficient catalysts and are often used in a number of industrial processes. A number of methods have been projected for the simultaneous determination of different metal ions like derivative spectrophotometry 3 , atomic emission spectrophotometry 4 , H-point standard addition [5][6][7][8][9][10] and the partial least square method [11][12][13] .…”

A novel protocol using H-point standard addition method (HPSAM) has been developed for simultaneous determination of cobalt and iron metals. We have herein focused on measurement of concentration of an analyte (cobalt) in the presence of other serving as the interfering species (iron). 4-[3-hydroxy-3-(4-methylphenyl) triaz-1-ene-1-yl] benzene sulfonamide (HTSN) was employed as the reagent in the presence of Triton x-100 which served as surfactant). The analytical signals were measured using two different wavelengths, λ1(390)and λ2 (418). The analytical utility of adopted method has been tested and verified under the optimized conditions such as- pH of the medium, colour development of complex and reagent concentration etc. The molar absorptivity was found to be74413 and 41691 L mol-1 cm-1 with excellent root mean square value 0.9992 and 0.9984 for Co (II) and Fe (III), respectively. The RSD values were1.01 and 2.56 for Co and Fe, respectively. The whole methodology is simple, rapid and cost effective. We have successfully applied this method the analysis of Co (II) and Fe (III) in synthetic samples.

Preferable, third-order nonlinear optical (NLO) single crystal, 3-Nitroanilinium chloride (3NACL) was auspiciously synthesised by slow evaporation technique. The crystal system of synthesised 3NACL crystal is triclinic with centrosymmetric space group was identi ed by single crystal XRD studies. All the functional groups present in the sample and its respective vibrations are analysed through FTIR analysis. UV-Vis transmittance spectrum revealed that the synthesised material was 83% transmittance and it cut-off wavelength was 276nm. The mechanical stability and thermal property of grown 3NACL crystals were ascertained by Vickers micro hardness analysis and TG/DTA analysis. The intermolecular interaction of the 3NACL was scrutinized by Hirshfeld surface analysis. Dielectric studies revealed that dielectric constant and dielectric loss were high at lower frequency region due to the space charge polarization. Inclusion free 3NACL crystal was used to analyse the Laser damage threshold (LDT) studies and its calculated LDT value was 4.3 GW/cm 2 . The third-order NLO parameters (β = 7.5472x10 − 12 m/W, η 2 = 5.6931x10 − 19 m 2 /W, χ 3 = 2.9491x10 − 13 esu) of the 3NACL material was statutory evaluated by Z-scan studied. Here, β and η 2 are positive value due to the saturated absorption and self-focusing effect was observed in open and closed aperture z-scan curve. Above all these ndings 3NACL was suitable material for NLO and optoelectronic applications.
