All cavities would need to be uniformly occupied by the guests. With those nice architectures awaiting to be filled, ordering molecules might appear like an easy task.ДЄs you imagine, things are more complex. Some porous silicas have large honeycomb channels, while the cavities of metal organic frameworks display an amazing variety of size and shape. But if you want to entrap, say, enzymes, peptides, or large nanoparticles, you must use materials with larger pores. Similar to honeycombs, regular patterns of pores like those in zeolites can orderly accomodate small molecules or clusters. Think of a buzzing swarm of bees, first frantically hovering in the air, and then accommodated in a honeycomb. This task gets easier when molecules are confined in regular pores. Tiny smart objects such as molecular machines, motors and diodes, make good use of self-organization processes, which createВ order from apparent disorder by exploiting interactions between molecules. The regular cavities of zeolites do a great job in organizing guest molecules Energy transfer or information storage, for instance, are made possible by the organizationВ of the confined molecules. This process, called вЂњconfinementвЂќ, brings to life new properties, which were not present in the individual molecules and are very useful in technology.

Once there, molecules are no longer free to move, like in a gas or a liquid. You can make materials for solar cells, optical devices or medical sensors by trapping molecules or nanoparticles inside a вЂњhostвЂќ. Like material science and mineral science. Why writing a long one? Perhaps, it might connect disciplines which speak different languages but have much in common. Probably weвЂ™d need more readable, shorter papers too. We live in the information overload era: too much to read, too little time, and life is short. Overwhelmed with the increasing flow of new scientific discoveries and related literature? YouвЂ™re not alone.
