Organometallic hybrid nanomaterials represent not only creative alternative materials and design new compounds in academic research but also enables deployment of a revolutionary industrial applications. Today, most of the hybrid materials are available in the market are synthesized and processed based on chemical engineering example of food preservation in the 80s of the 20th century.
The new generation of nanomaterials continuous development through academic research has been a sweet fruit for profitable applications in the fields of optics, electronics, solid-state ion transmission, engineering, energy, environment, biology, medicine. The specific application can be seen as filters, separators, intelligent mulch, fuel cells, solar cells, catalysts, sensors, etc. ...
Through the mechanism of sol-gel synthesis classics, we have hybrid network of amorphous materials. This network formed by hydrolysis of metal alkoxide has been modified alide organic or metal, and metal alide was condensed with metal alkoxide. Solvents may contain organic molecules, biomolecules or multifunctional polymer that can create or interact with crosslinked or trapped inside the inorganic hybrid nanomaterials through interactions (inter- hydrogen, pp interactions, Val der Waals forces). User simpler, cheaper, and create hybrid nanomaterials amorphous. This material micro structure is not defined, transparent and easy to shape or block membrane. We have multi size dispersion and heterogeneity in chemical composition. However, synthetic materials available from this direction, versatile, has many physical properties are of interest and commercial applications in the form of film or monolith blocks. Currently, the structure of local control or local sales organization as well as the level of this type of material is the key issue in creating integrated as standard quality.
The substance was created as a bridge silsesquioxane X3Si-R9 example of food preservation R9-SiX3 with the original bridge organic substances, X is the original example of food preservation Cl, Br, OR. Using these materials allows example of food preservation the fabrication of hybrid organometallic materials with molecular uniformity example of food preservation and better example of food preservation local organizations. The combination of the components of the organic bridging alkyl groups, aromatic ring, and the process of self-ure help better connected thanks to the ability to create a strong hydrogen bonding network example of food preservation and efficient sort through the interaction of the pp half of the organic segment.
Hydrothermal example of food preservation synthesis method in polar solvents (water, formamide, etc. ...) in the presence of organic molecules pattern for the zeolite product. The product has a very high surface area. Some hybrid example of food preservation zeolite materials from nature or power. The product framework-metal structure (metal-organic framwork example of food preservation MOF) away from this method is currently a candidate for catalytic applications and adsorbed gas.
User B chemically related to connectivity (direction B1), or the fragmentation (B2 direction) blocks available nano has been formed example of food preservation (well-defined block-nanobuilding NBB). The block is available nano form elements are edited and ready structure integrated example of food preservation into the base material. The NBB may be the molecular beam or bundle, nanoparticles are attached or fixed before the organic functional groups (metal oxides, metals, example of food preservation oxides of group VI elements, compounds form shell-core nano or nano classes (clay, the depth hydroxide layers, the layers form phospate, oxide group VI elements.) The NBB is capable of inserting into the cup of organic ingredients. Besides, they can be wrapped or ligands connected to the root bridge organic example of food preservation substances, such telechelic molecules or polymers or dendrimers were functionalized. use predefined groups of the advantages of this structure:
NBB diversity of nature, structure, and function and the links created to allow the muscle architecture-metal interface corresponding to different combinations of different types. In addition, each level synthesis allows better control of the intermediate structure in the process. Group uses material from NBB is important clay nano materials. We have been commercialized from the separation results inserted, swelling and dissolution of the nano clay.
In ten years, this new direction is synthesized and studied surveying and bring success in developing hybrid materials. This success example of food preservation involves the ability to control
