High-resolution scanning electron microscopy (HR-SEM) with backscattered electrons (BSE) under a low accelerating voltage provided images with compositional information about Pt nano-particles with a diameter of approximately 6 nm that were dispersed in mesoporous silica (SBA-15). The dispersion of Pt nano-particles in mesoporous silica was investigated using the BSE imaging method in combinati...

Single step pretreatment-saccharification of corn stover was investigated in aqueous p-toluenesulfonic and sulfuric acid media. Dilute aqueous solution of p-toluenesulfonic acid was a better catalyst than aqueous sulfuric acid of the same H(+) ion concentration for single step pretreatment-saccharification of corn stover at moderate temperatures and pressures. For example, 100mg corn stover hea...

in the present study, sulfuric acid was used for artemia cysts decapsulation. cysts of artemia franciscana were hatched out in regular manner or following hypochlorite or acid decapsulation. two acid concentrations (1 and 5%), three acid immersion times (10, 30 and 50 min) were used and hatching rates were recorded after 15, 18 and 24 h incubation. hatching rates increased but hatching time dec...
