Here we report synthesis and characterization of chemically synthesized calcium hydroxide (Ca(OH)2) with and without deliberate presence of NaNO3 as an impurity. Calcium nitrate tetrahydrate (Ca(NO3)2.4H2O) is used as precursor and alkaline NaOH solution is used as precipitant to synthesize the Ca(OH)2 samples. The samples were characterized by XRD, FESEM, FTIR spectroscopy, DTA, TGA and UV-Vis spectroscopy techniques. From the UV-Vis spectroscopy results, it is found that the Ca(OH)2 with NaNO3 impurity has higher bandgap than the sample without NaNO3. The weight loss in TGA is also more for the Ca(OH)2 with impurity than the one for without impurity. The results are discussed in terms of composition formed during synthesis process.

“…The larger is the number of dislocations stored per unit area, the more becomes the residual strain () in-built in the sample. To test this hypothesis, the size strains due to the nano-crystalline sizes were estimated by the well-known Williamson-Hall method as [13]:…”

“…Numerous analysts have put forth different attempts in creating transition metal based oxide (essentially got from Mn 3 O 4 ) nanoparticles through various synthesis techniques, for example, ultrasonic technique [21],co-precipitation [22,23], auto-burning [24], solid state reaction [25,26], ball milling process [27,28], sol-gel [29] techniques and others. In light of the methods referenced above, we apply the co-precipitation route because of its simplest and adequacy in creating the nanomaterials.…”

The Co1-xCuxMn2O4 samples were effectively synthesized by means of chemical reagents and highly scalable co-precipitation technique. X-ray diffraction investigation affirmed the tetragonal structure possessed by Co1-xCuxMn2O4 with crystal size ranging from 12 nm to 22 nm. The crystallite size and micro strain values were correlated using Williamson-Hall plot and size-strain plot method. SEM images showed highly porous, less dense, agglomerated grains with grain size from 3.93 ?m to 13.73 ?m. Vibrational characterization of the samples was completed using FTIR spectra and Raman spectra which affirm the tetragonal structure. The magnetic characterization demonstrates the ferromagnetic nature of the materials which varies with copper substitution

The motto of the work investigates the synthesis of silver nano-particles by simple and economic green synthesis. With aid of citrus fruit that is lemon peel extract under different conditions, Characterization of silver nano-particles was carried out by using ultra-violet visible spectroscopy, X-ray diffraction, Fourier transferred infrared spectroscopy. The antimicrobial activities of synthesized silver nano particles (AgNPs) characterized by well diffusion method (WDM). Lemon peel extract mediated silver nano particles showed significant antimicrobial activity and have attention of pharmacists in order to design medicines. The results of antimicrobial test on the lung cancer cell has been witness the synthesis of drugs using extracted lemon peel is emerged as an eco-friendly, cost effective and most attentive synthesis.
