Differential thermal analysis has been used for quantitative determination of heats of aluminothermic redox reaction of MnO2 and V2O5 over a wide range of temperatures. Heat of reaction V2O5-Al and MnO2-Al systems have ...

Based on detailed study of the interference effects encountered at sodium resonance line at 589.0 and that of potassium at 767.5 nm, a method has been developed for the determination of sodium and potassium in standard ...

A great deal of effort has been directed towards the development or economically and technically feasible processes for the chemical extraction of P2O5 from basic slags, which is a by-product in the manufacture of steel. ...

The kinetics of oxidation of ammonium sulfite using gaseous oxygen were studied in an autoclave at 373K. Kinetic equations for various catalysts such as Cu(II), Co(II) and Ag(I) were determined. The reaction rate at 373K ...

Foliar application of gibberellin (GA(3)) to patchouli (Pogostemon cablin Benth.) increased the plant height, number of nodes per plant, leaf fresh mass and photosynthetic pigment contents. The content of chlorophyll (Chl) ...
