Abstract. Aromatics contribute a significant fraction to organic compounds in the troposphere and are mainly emitted by anthropogenic activities biomass burning. Their oxidation lab experiments is known lead formation of ozone aerosol precursors. However, their overall impact on tropospheric composition uncertain as it depends transport, multiphase chemistry, removal processes intermediates. Re...

Cobalt ferrite nano-powder have been obtained through a hydrothermal method with 2:1 molar ratio of Fe:Co without using any surfactant. X-Ray Diffraction (XRD) and Scanning Electron Microscopy (SEM) were used to consider the structural and morphological properties of CoFe2O4 nano-particles. Also, EDAX spectroscopy applied to evaluate the chemical composition. Results demonstrated that 15 hr hyd...

The applicability of the X-ray powder diffraction method to the determination of phase composition and Ca/P ratio in precipitates during the nitrous wet synthesis of hydroxyapatite (HA) has been shown. The plotted dependences of the phase composition and the Ca/P ratio on the synthesis time can be used as initial data for the development of new and simple processing routes of calcium phosphate ...

Asperula glomerata, the plants belonging to value and range are protein classes in a three stage, active vegetative growth, flowering and seed respectively, is equal to 9/9, 10/1, 9/6. This plant also aspects of soil conservation are also important. In the treatment of diseases such as lowering blood pressure is use to reduce inflammation.   Asperula glomerata in 1389 in two stage, active veg...

The phase equilibria in two prototype alloys with nominal compositions 60Nb-20Pd-10Hf-10Al and 40Nb-30Pd-15Hf-15Al (in at. pct) are investigated using scanning electron microscopy and X-ray diffraction. The alloys were heat treated at 1200 °C and 1500 °C for 200 hours each. The phase analysis revealed that the alloys were, for the most part, in the three-phase equilibrium between (Nb), Pd2HfAl,...
