$(1$ pt$)$ What is the difference between a film and a membrane?

$(1pt)$ 'What are the key features of membranes that makes them good for gas separation?

$(1$ pt$)$ What is the main appeal of membrane separations relative to thermal separations?

$(1$ pt$)$ What are the "building blocks" of the structures of MOFs and Bio MOFs?

$(1$ pt$)$ What are some features of Bio MOF$-1$ that make it attractive as membranes for gas separation?

$(1$ pt$)$ Given the large pores of Bio MOF$-1,$ is its perm$-$selectivity primarily controlled by ratios of adsorption coefficients $($thermodynamically controlled$)$ or by ratio of diffusion coefficients $($kinetically controlled$)?$
