Oriented growth and assembly of zeolite crystals on substrates

Chinese Science Bulletin 2008年第6期53卷 801-816页

作者： ZHOU Ming ZHANG BaoQuan liu xiufeng School of Chemical Engineering and Technology Tianjin University Tianjin 300072 China

The aligned array and thin film of zeolites and molecular sieves possess a variety of potential applica- tions in membrane separation and catalysis, chemical sensors, and microelectronic devices. There are two main synthesis methods for manufacturing the aligned arrays and thin films of zeolites and mo- lecular sieves, i.e. in situ hydrothermal reaction and self-assembly of crystal grains on substrates. Both of them have attracted much attention in the scientific community worldwide. A series of significant progress has been made in recent years. By the in situ hydrothermal synthesis, the oriented nucleation and growth of zeolite and molecular sieve crystals can be achieved by modifying the surface properties of substrates or by changing the composition of synthesis solutions, leading to the formation of uni- formly oriented multicrystal-aligned arrays or thin films. On the other hand, the crystal grains of zeo- lites and molecular sieves can be assembled onto the substrate surface in required orientation using different bondages, for instance, the microstructure in the array or thin film can be controlled. This review is going to summarize and comment the significant results and progress reported recently in manufacturing highly covered and uniformly aligned arrays or thin films of zeolites and molecular sieves. It involves (1) in situ growth of highly aligned zeolite arrays and thin films via embedding func- tional groups on the substrate surface, modifying the surface microstructure of substrates, as well as varying the composition of synthesis solutions; (2) assembly of zeolite and molecular sieve crystals on various substrates to form aligned arrays and thin films with full coverage by covalent, ionic, and in- termolecular coupling interactions between crystals and substrates; (3) coupling surface assembly with microcontact printing or photoetching technique to produce patterned zeolite arrays and thin films. Finally, the functionality and applications of zeoli

Pure CoAPO-36 crystal grains were synthesized by hydrothermal reaction. Porous α-Al2O3, stainless steel and K2Ti6O13 supported CoAPO-36 films were fabricated using in situ crystallization for the first time. SEM images and XRD measurements demonstrate that a continuous CoAPO-36 film was obtained on the K2Ti6O13 substrate. Diffuse reflectance UV-Vis spectra indicate that Co2+ has been incorporated into the ATS framework. Both CoAPO-36 crystal grains and the K2Ti6O13 supported CoAPO-36 film exhibit satisfactory catalytic activities for the oxidation of cyclohexane.

Relationship Research between the Chinese Medicine Constitution and Sub-Health

引用

Engineering（科研） 2013年第10期5卷 429-432页

作者： xiufeng liu Bo Xu Zhenhu Chen School of Medical Information Engineering Guangzhou University of Chinese Medicine Guangzhou China

With further development of the bio-psycho-social medical model, people began to re-examine the knowledge of disease and health. The concept of sub-health has also been proposed in western medicine. Because of the lack of a specific standard, it is difficult to make clinical diagnosis and treatments for sub-health. Chinese medicine constitution theory has been widely accepted in China, and has a set of executable standards. This paper puts forward a new research method that connects the sub-health in western medicine and Chinese medicine constitution theory together. The potential relationships and influences between Chinese medicine constitution theory and sub-health were analyzed and key content and research progress were discussed. The research method in this paper will provide new ideas for sub-health research.
