There is, I think, something ethereal about i —the square root of minus one. I remember first hearing about it at school. It seemed an odd beast at that time—an intruder hovering on the edge of reality.

Usually familiarity dulls this sense of the bizarre, but in the case of i it was the reverse: over the years the sense of its surreal nature intensified. It seemed that it was impossible to write mathematics that described the real world in …

I and i

Synthesis of metal-organic frameworks (MOFs): routes to various MOF topologies, morphologies, and composites.

The boundary layer equations for plane, incompressible, and steady flow are 

$$\matrix{ {u{{\partial u} \over {\partial x}} + v{{\partial u} \over {\partial y}} = - {1 \over \varrho }{{\partial p} \over {\partial x}} + v{{{\partial ^2}u} \over {\partial {y^2}}},} \cr {0 = {{\partial p} \over {\partial y}},} \cr {{{\partial u} \over {\partial x}} + {{\partial v} \over {\partial y}} = 0.} \cr }$$

Boundary Layer Theory

After three decades of intense and fundamental research on metal–organic frameworks (MOFs), is there anything left to say or to explain? The synthesis and properties of MOFs have already been comprehensively described elsewhere. It is time, however, to prove the nature of their true usability: technological applications based on these extended materials require development and implementation as a natural consequence of the up-to-known intensive research focused on their design and preparation. The current large number of reviews on MOFs emphasizes practical strategies to develop novel networks with varied crystal size, shape and topology, being mainly devoted to academic concerns. The present survey intends to push the boundaries and summarise the state-of-the-art on the preparation of promising (multi)functional MOFs in worldwide laboratories and their use as materials for industrial implementation. This review starts, on the one hand, to describe several tools and striking examples of remarkable and recent (multi)functional MOFs exhibiting outstanding properties (e.g., in gas adsorption and separation, selective sorption of harmful compounds, heterogeneous catalysis, luminescent and corrosion protectants). On the other hand, and in a second part, it intends to use these examples of MOFs to incite scientists to move towards the transference of knowledge from the laboratories to the industry. Within this context, we exhaustively review the many efforts of several worldwide commercial companies to bring functional MOFs towards the daily use, analysing the various patents and applications reported to date. Overall, this review goes from the very basic concepts of functional MOF engineering and preparation ending up in their industrial production on a large scale and direct applications in society.

Multifunctional metal–organic frameworks: from academia to industrial applications

Owing to the vast diversity of linkers, nodes, and topologies, metal–organic frameworks can be tailored for specific tasks, such as chemical separations or catalysis. Accordingly, these materials have attracted significant interest for capture and/or detoxification of toxic industrial chemicals and chemical warfare agents. In this paper, we review recent experimental and computational work pertaining to the capture of several industrially-relevant toxic chemicals, including NH3, SO2, NO2, H2S, and some volatile organic compounds, with particular emphasis on the challenging issue of designing materials that selectively adsorb these chemicals in the presence of water. We also examine recent research on the capture and catalytic degradation of chemical warfare agents such as sarin and sulfur mustard using metal–organic frameworks.

Metal–organic frameworks for the removal of toxic industrial chemicals and chemical warfare agents

In this study, a relevant literature has been reviewed focusing on the carbon dioxide capture technologies in general, such as amine-based absorption as conventional carbon dioxide capturing technology, aqueous ammonia-based absorption, membranes, and adsorption material (e.g., zeolites, and activated carbons). In more details, metal organic frameworks (MOFs) as new emerging technologies for carbon dioxide adsorption are discussed. The MOFs section is intended to provide a comprehensive overview of MOFs including material characteristics and synthesis, structural features, CO2 adsorption capacity, heat of adsorption and selectivity of CO2.

A novel combined manufacturing technique for rapid production of IRMOF-1 using ultrasound and microwave energies

Cancer is the uncontrolled growth of cells in the body and is considered as one of the major causes of death globally. There are several cytotoxic chemotherapeutic agents used to treat cancer including methotrexate, 5-fluorouracil, cisplatin, tamoxifen, doxorubicin and others. Although billions of dollars have been spent on cancer research to develop these chemotherapies, it still remains a major illness for mankind partly due to the shortcomings of these therapies. These shortcomings include low targeting specificity, severe side effects (due to high doses) and poor pharmacokinetics. To avoid these drawbacks, anti-cancer drug delivery systems have been developed recently using nanocarriers including liposomes, micelles, polyelectrolyte capsules and others. One of the recent class of nanoparticles investigated for chemotherapeutic use are metal organic frameworks (MOFs) which are hybrid polymers that consist of metal ions or clusters and organic ligands. MOFs are used in many applications including gas/vapor separation, gas storage, catalysis, luminescent materials, and biomedical imaging. These structures have additional features that promote their use as drug carriers in the biomedical field. First, they are nontoxic, biodegradable and have the ability to carry high loadings of the anti-neoplastic agent due to their porous nature. Also, they have well-defined crystalline structures that can be characterized by different analytical techniques and their sizes are suitable to control their in vivo drug release. This paper reviews the methods used to synthesize MOFs and their recent use as antineoplastic drug delivery carriers.
