Rasasindura is a one of Kuppipakva Rasayana a unique method of preparation and is one such imperative Kupipakwa Rasayana, referred to be Elixir of life. It is formulated by two fundamental substances of Rasashastra i.e., Shudha Parada and Shudha Gandhaka. It is said to be prepared by same process but with different proportion of Gandhaka, and accordingly various forms of Rasasindura are named as Ardhaguna, Samaguna, Dviguna, Triguna, Chaturguna, Panchaguna, Shadguna balijarita Rasasindura, where in, the therapeutic merits of Rasasindura and pharmaceutics of Rasasindura changes according to quantum of Gandhaka. Rasasindura is a Sagandha, Sagni and Bahirdhooma Kupipakwa Rasayana. Samaguna balijarita Rasasindur was prepared with equal quantities of Parada and Gandhaka by Kupipaka method in 20 hours and physicochemical analysis was carried out. Ash values in Samagunabalijarita Rasasindur were found to be 0.02%. Free mercury was nil in Samagunabalijarita Rasasindur where as its traces were present in the Kajjali. Free sulfur traces were present in Samagunabalijarita Rasasindur. Total mercury percentage in Samaguna Kajjali was 36.02%. Total mercury percentage in Samagunabalijarita Rasasindoor was 83.15%. Total sulfur percentage in Samagunabalijarita Rasasindoor was 13.06%. By XRD analysis Samagunabalijarita rasasindur was identified as Cinnabar having Hexagonal crystal structure with primitive lattice.

Analytical study of any drug is essential to standardize it. Analytical study is carried out to check drug quality. For this purpose some analytical tests are performed and their results are compared with standard parameters. The drug fulfilling these criteria can be taken as standard drug and can be used for therapeutic purpose. Percentage of total mercury in Shadguna Kajjali and Shadguna balijarita rasasindur was 40.03%, and 84.17%. Total Sulphur in Shadguna Kajjali and Shadguna balijarita rasasindur was 43.07% and 11.16%. Percentage of free sulfur in Shadguna Kajjali and Shadguna balijarita rasasindur was 22.11%. XRD of Shadguna balijarita Rasasindur were identified as Cinnabar (Hgs) with Hexagonal Crystal Structure having primitive lattice. In this paper Physico-Chemical Analysis of Shadguna Kajjali and Shadguna balijarita rasasindura is done.

A new ternary compound Cu2SnTi3 has been synthesized by vacuum sintering at 900 °C. The atomic structures of CaCu5- and InNi2-like Cu2SnTi3 are calculated using density functional theory methods. The X-ray diffraction (XRD) analysis and selected area diffraction (SAD) patterns of the new ternary compound Cu2SnTi3 are considered to verify the atomic structures of CaCu5- and InNi2-like Cu2SnTi3. The results reveal that the InNi2-like Cu2SnTi3 model has the lowest total energy of −35.239 eV, representing the trigonal crystal structure. The orthorhombic crystal structure of the CaCu5-like Cu2SnTi3 model has the second lowest total energy of −33.926 eV. Our theoretical X-ray diffraction peak profiles of InNi2-like (CaCu5-like) Cu2SnTi3 are nearly identical to experimental one, leading to an error below 2.0% (3.0%). In addition, the hexagonal crystal structure of the CaCu5-like Cu2SnTi3 model has the highest total energy of −33.094 eV. The stability of the Cu2SnTi3 in terms of energy follows the order: the trigonal, orthorhombic, and hexagonal crystal structure.

Nanocrystalline ZnO powders have been synthesized by a novel combustion synthesis method using glycine and urea as mixed fuels and zinc nitrates as oxidant. The as-synthesized ZnO powders are characterized by DSC, XRD and SEM. Results show that the as-synthesized ZnO powders show well crystalline with hexagonal crystal structure and purity without any other impurities and the particle sizes are about 50~70nm calculated by the Scherrer formula.

Crystal structure of Zn0.96Al0.02Ga0.02O was analyzed by X-Ray diffraction (XRD) technique and the microstructure was observed by scanning electron microscopy (SEM), and transmission electron microscopy (TEM). The XRD results showed single phase and hexagonal structure a = b = 3.24982 Å, and c = 5.20661 Å. The SEM and TEM results showed the grain size of material arrangement changed after sintering and TEM diffraction pattern confirmed hexagonal crystal structure of Zn0.96Al0.02Ga0.02O after sintering.

Background: Shilajatu or Adrija is one of the Maharasa, which is considered as a wonderful medicine in Ayurveda. It is named as it comes out of the stones heated by the sun in summer in the form of thick blackish exudation having many shades. Since it contain stone, mud, wood, sand and various physical and metallic impurities, Shodhana (Purification) of Shilajatu is a mandatory procedure. It has been used as a prime ingredient in many formulations mainly for Prameha, Sotha, Pandu Roga, Kshaya, Swasa, Pliha Vrudhi, Jwara, Agnimandya, Apasmara, etc. Objectives: Shodhana of Ashudha Shilajatu and Physico chemical analysis of Shodhita Shilajatu. Materials and Methods: Bhringaraja Swarasa for Shodhana of Shilajatu. Results:It took 8 days for completion of Shilajatu Shodhana. XRD Analysis report indicates that the sample Shilajatu was Amorphous material. Conclusion: Total yield of Shodhita Shilajatu was 99.6%. The Sample of Shilajatu was found to be Amorphous material in XRD Analysis hence crystal structure was not identified.
