both making dificult the access of the sulfonic group to the reaction sites. 12 observed the shift of the T max to lower temperature in their work on

The new Ca 2 CoTaD 6 double perovskite has been synthesized by a conventional solid state reaction and its unit cell parameters determined by X-ray powder diffractometry..

Adding silica produces a reduction in the early pH and a decrease in setting times; nevertheless, the presence of more calcium silicate hydrate (C-S-H) delays the growth

Table 2(e) presents the results in terms of adsorbed protein, yield and amount of lipase immobilized and esteriication activity of porcine pancreatic lipase using

The products of combustion were used to synthesize the carbon nanomaterials (CNMs) at the presence of a catalyst.. CNMs have a wide range of potential applications due to their

Higher photoactivity was obtained for the BF900 and BF1000 samples, where the speciic surface area is higher and the presence of BaFe 2 D 4 is more evident (Figure 2). Indeed,

conventional polymer composite pipes currently used do not allow non-destructive evaluation (NDE) using instrumented pigs which operate with magnetic sensors.. Approaches to

The AlCrN coating promoted, compared to the uncoated insert, an increase on the hardness of the surface cutting tool, a better tribological behavior and consequently a
