1 Homework 2 Submission deadline: 1 April

1. Apply the linear Dubinin-Radushkevich plot if your system is microporous

From the linear fit conclude the p/p0 range where the fit can be used.

Get the best fit, conclude the slope, the intercept and the regression (R or R2)

From the intercept calculate the micropore volume (conversion is similar as in Homework 1)

2. Supposing that all the molecules filling the micropores have direct contact with the surface estimate the surface area of the micropores

3. Summarize your results in a table (see next slide) 4. Compare BET and DR surface areas. Are you puzzled?

Any hint for explanation?

But this is the chronology of Oedipus’s life, which has only indirectly to do with the actual way in which the plot unfolds; only the most important events within babyhood will

a) There is an idealized surface or surface phase separating two homogeneous bulk phases (see Figures 1 and 2). The bulk phases are in equilibrium with the surface or surface phase.

Based on the results the minimum normal elastic strain of the surface of the driving bevel gear is developed in case of z 1 =24 number of teeth in absolute value.. The

The reduced levels of NKCC1 and CFTR mRNA in duct cells derived from diseased animals suggest the active contribution of these transporters in lacrimal fluid secretion as the

Any direct involvement in teacher training comes from teaching a Sociology of Education course (primarily undergraduate, but occasionally graduate students in teacher training take

The decision on which direction to take lies entirely on the researcher, though it may be strongly influenced by the other components of the research project, such as the
