Introduction: Mrityunjaya Rasa is a Herbo-Mineral formulation, mentioned in Jwara Chikitsa along with various Anupana like Madhu, Aardraka Swarasa, and Jeeraka Kashaya with Guda. Ingredients like Shudha Hingula, Shudha Gandhaka, Shudha Vatsanabha, Shudha Tankana, Pippali and Maricha with properties of Tikta, Katu Rasa Teekshna Guna and Deepana-Pachana, Swedajanana, Yogavahi and Jwaraghna action show the significant result on various types of fever. To attain desired qualities in the finished product, it is much needed to check efficacy on modern parameters for standardization purposes. Thus, Mrityunjaya Rasa was subjected to X- ray diffraction spectroscopy to ensure SOPs followed for preparation. Aim: The study aimed to analyse the results of X-ray diffraction spectroscopy of Mrityunjaya Rasa. Materials and Methods: X-ray diffraction spectroscopy of Mrityunjaya Rasa was carried out at MIT–central instrumentation facility – innovation centre, Manipal, Udupi. Results: XRD study indicates that Mrityunjaya Rasa contains HgS (cinnabar), mercury sulphide in major phase and borax and elements Na, Ca, Mn, Mg, K, P, Zn, C, Cl2, Fe and B in minor phase. Conclusions: Mrityunjaya Rasa contains HgS (cinnabar), mercury sulphide in major phase and borax and other elements like Na, Ca, Mn, Mg, K, P, Zn, C, Cl2, Fe, and B are also present. Compounds and elements are present due to ingredients and Shodhana media which were used. This study can be a path for establishing the thumbprint of SOP for Mrityunjaya Rasa, a herbomineral compound formulation. Keywords: Mrityunjaya Rasa, XRD, HgS, S, Borax, Na, Ca, Mn etc.

Cordierite was synthesized via glass-route using mineral and pure oxide material. Kaolin, talc, dolomite, magnesia, alumina, silica, and calcium oxide were mixed and melted. CaO from mineral and pure oxide was added in order to investigate the properties of each material in cordierite system. Sample was characterized using X-ray diffraction (XRD) analysis and dilatometer testing. The result showed that when 5wt% CaO from mineral (C5 Min) was added and sintered at 900°C, α-cordierite exist as major phase and anorthite as a minor phase. While for a sample consists of 5wt% CaO from pure oxide (C5 Ox), α-cordierite was present as major phases, µ-cordierite and anorthite as minor phases. Crystallite sizes of each material were in nanorange and crystallite size of C5 Ox was less than C5 Min.

Product Powder

The nickel sulfides of NiS and NiS2 have been synthesized successfully at 180 °C and 160 °C by hydrothermal method from NiCl2•6H2O, S powder and NaOH. The phases and morphology of the products were characterized by X-ray diffraction (XRD) and transmission electron microscopy (TEM) respectively. Experimental results show that, the major phase of the powder product obtained at 180 °C is NiS2. The Ni-S powder obtained at 180 °C shows granular and hexagonal shapes with sizes of about 200~300 nm. The product powder obtained at 160 °C has the major phase NiS and minor phase NiS2. The morphology of this product was regular hexagonal flakes with side-length 200nm.

Direct Nitridation

A novel method was developed to produce Al2O3/AlN composite powders. The composite powders were synthesized by the direct nitridation of Al2O3using various additives by plasma processed with two different types of gas (Ar/N2and N2plasma). The effects of these two different plasma gases and additives on the formation of the Al2O3/AlN composites were studied. The x-ray diffraction results in the composite powders showed that the cubic AlN was converted to the major phase while transient γ–Al2O3was the minor phase when the composite powder was fully melted using nitrogen as the sole working gas. In contrast, the main phase was still α–Al2O3when the composite powder was not well melted using the mixture of argon and nitrogen as the working gas. Carbon was found as an effective conversion additive to increase the cubic AlN of this composite powder up to 49 vol%. The reaction mechanism of forming this composite powder was also analyzed.

Boiling Toluene

Thermolysis of [8,8-(PMe2Ph)2-nido-8,7-PtCB9H11] in boiling toluene solution results in an elimination of the platinum centre and cluster closure to give the ten-vertex closo species [6-(PMe2Ph)-closo-1-CB9H9] in 85% yield as a colourles air stable solid. The product is characterized by NMR spectroscopy and single-crystal X-ray diffraction analysis. Crystals (from hexane-dichloromethane) are monoclinic, space group P21/c, with a = 903.20(9), b = 1 481.86(11), c = 2 320.0(2) pm, β = 97.860(7)° and Z = 8, and the structure has been refined to R(Rw) = 0.045(0.051) for 3 281 observed reflections with Fo > 2.0σ(Fo). The clean high-yield elimination of a metal centre from a polyhedral metallaborane or metallaheteroborane species is very rare.

Dinuclear rhodium(I) η2:η2-cycloocta-1,5-diene (series a) and η2:η2-norborna-2,5-diene (series b) complexes with μ-RCOO- ligands, where R is linear C21H43 (complexes 1a, 1b), CH2CMe3 (2a, 2b), 1-adamantyl (3a, 3b) and benzyl (4a, 4b), have been prepared and characterized by spectroscopic methods. Structures of complexes 2b, 3a and 4a were determined by X-ray diffraction analysis. Complexes prepared show low to moderate catalytic activity in polymerization of phenylacetylene in THF giving high-cis-transoid polymers, but they show only oligomerization activity in dichloromethane.
