Xray diffraction methods are the most effective methods for determining the crystal structure of materials. Diffraction methods can identify chemical compounds from their crystalline structure, not from their compositions of chemical elements. It means that the different compounds (or phases) that h[r]
transition metals, as compared with those of the first-row metal elements, even thoughthe relation remains not linear. In fact, the bond dissociation energies of V 2 and Nb2are determined to be 2.75 ± 0.0126 and 6.20 ± 0.05 eV,27 respectively, while that ofTa2 is predicted to be in the[r]

Weeds are the part and partial of crop production since evolution of agriculture. Because of their superiority, efficiently harness favourable microclimate at the cost of crop. They mainly compete for mineral nutrients, soil moisture, space and light interception. In berseem field we can successfull[r]
Bioassay guided fractionation led to the isolation of a new triterpene glycoside, holothurinogenin B (1) along with three known compounds, holothurin B (2), holothurin A (3), and holothurin A2 (4), from the methanol extract of the Vietnamese sea cucumber Holothuria scabra. Their structures were dedu[r]

Volcanic ejecta or lahar can serve as an inorganic support for the immobilization of invertase. Pampanga and Bicol lahar samples were pretreated by ignition at 550o C for 5 hrs followed by concentrated hydrochloric acid treatment, activated by reaction with aminopropyltriethoxysilane (APTS) and then[r]
