Omar Yaghi: Water with solar light

 Omar Yaghi was the first to work in synthesis with the new crystalline matherials MOF and COF, gather many properties desired by the chemists, among them a great capacity to absorb other compounds, that are lodged withing their pores. having a big impact in sciencie and engineering , and it has potential applications of much interest as "the capture and storage of carbon dioxide (CO2),And the water molecules present in the air to generate drinking water.                       
He has created new materials based on brick assemblies. This strategy has led to exponential growth in the creation of new materials with unprecedented diversity in chemistry. At this new pitch its called Reticular ChemistryThey are very resistant molecular blocks for extensive structures The MOFs (metal organic frameworks) and the COF (covalent organic frameworks) are like crystalline sponges on a molecular scale Materials in which the holes form an ordered net and have a size controllable to measure. They 
According to Yaghi, if a single gram of MOF were deployed in a single, atomic-scale, pore-free film, it would cover 60 tennis fields.COF are composed of organic materials, while MOF combines inorganic materials (meta oxides and organics). In this case, the metal oxides are the hooks – where the molecule that must be caught is chemically adhered – and the organic compounds are the ligands that hold them together forming the great porous structure.
