This multi-scale and multi-technique work investigates the adsorption of phosphated species on TiO 2 anatase surface. Our original approach declines for first time progressive ethyl substitution phosphates to identify structure complexes formed upon these molecules in aqueous dispersions, under various pH conditions. To quantify adsorbed amount , isotherms were recorded as a function pH. In par...

silica refractory bricks are used especially in the metallurgical industries, due to desirableproperties such as particularly their high melting point and their rigidity and strength at hightemperatures. in this research, different amount of sic were added to silica refractory containingdifferent binders such as borax, boric acid, calcium nitride, sodium tri poly phosphate, sodiumhexametaphosph...

1,N6-Etheno-7-deaza-2,8-diazaadenosine (4) was synthesized from 8-aza-7-deazaadenosine (6) in 64% overall yield. The starting material 6 was obtained by the direct glycosylation of 8-aza-7-deazaadenine (7) with 1-O-acetyl-2,3,5-tri-O-benzoyl-beta-d-ribofuranose (8) (NO2 CH3, BF3 x Et2O; 77% yield). Compound 4 was transformed into 7-deaza-2,8-diazaadenosine (5). The fluorescence of compound 4 sh...

his paper serves to review a series of studies re-investigating the relative energy system contribution to track running events between 100m and 3000m. The relative contribution and interaction of the respective energy systems for the provision of Adenosine tri-phosphate (ATP) during track running is of importance in order to understand the metabolic demands of an athletic event. This knowledge...

Recently, dynamic approach has been applied to determine the steady state concentrations of multiple ionic species present in complex buffers at equilibrium. Here, we have used the dynamic approach to explicitly model the pH profiles of biologically relevant phosphate buffer and universal buffer (a mixture of three tri-protic acids such as citric acid, boric acid and phosphoric acid). The resul...
