Understanding excess uptake maxima for hydrogen
adsorption isotherms in frameworks with rht topology
For a series of metal–organic frameworks with rht topology, we study computationally the effect of the linker length on the surface area, pore size, and pore volume, relating them with the hydrogen adsorption properties. The results provide new insights about the excess capacities and the pressures where the uptake maxima in the excess isotherms occur.

Facile synthesis of metal–organic framework films via in situ seeding of nanoparticles
A facile in situ nanoparticle seeding method is reported to prepare MIL-101(Cr) films on alumina supports. The in situ seeding of MIL-101(Cr) nanoparticles was promoted by use of dimethylacetamide. The generality of this approach is further demonstrated for Cu3(btc)2 films by using a (poly)acrylate promoter.
