lia; Monash University; Swinburne University of Technology), Italy (Associazione CIVEN) and Austria (Institute of Biophysics and Nanosystems Research, Austria) managed to manufacture highly- structured, porous crystals with multidimensional structures and extremely large surfaces.
A
They developed a special method that allows con- trolling place and type of crystal growth and also the speed of growth. One gram of that material has a surface of more than three football fields. The spa- cious pores can be used as sponges that can store gases like hydrogen, carbon dioxide or natural gas. Furthermore, they could be used as nano-filter for gas or liquid purification.

The controlled nanometre-sized pores and surface areas of thousands of square metres per gram, Metal- Organic Frameworks (MOFs) may have an integral role in future catalysis, filtration and sensing appli- cations.
