THEORETICAL AND PRACTICAL ASPECTS OF Colloid SCIENCE AND SELF-ASSEMBLY PHENOMENA REVISITED
Reviews in Chemical Engineering, 2007Co-Authors: Vuk UskokovićAbstract:Colloid Chemistry and self-assembly phenomena present an essential aspect of the design of fine material structures and devices in the coming era. Numerous uncertainties, however, pervade this practical field, including the questionable processing potential of pre-synthesized self-assembled systems in the design of advanced material structures. Despite the current belief in advancement of knowledge on stereoscopic molecular recognition and molecular assembly manipulation that might eventually open the door to perfect control inherent in the design and processing of ultra-fine macroscopic structures, trial-and-error interactive aspects seem to be inherent not only to the synthetic approaches in the frame of contemporary Colloid Chemistry, but to biomolecular recognition processes as well. After referring to the historic trend of descent of scientific interest towards physical processes that occur at ever finer size scales in the first and introductory section, the next section describes the basic notions and the founding aspects of the field of Colloid Chemistry. Dichotomy of the so-called top-down and bottom-up approaches to the design of ultra-fine structures and technologies is first mentioned in the Sec.3. The prospects and demerits of both synthetic methodologies are discussed in the same section. The basics of the conceptual framework of DLVO theory, altogether with the major approximations and the resulting limitations in its application, are discoursed in Sec.4. The relationships between theoretic and experimental variables in the framework of Colloid Chemistry are first expounded in Sec.5, in which numerous examples of pronounced sensitivities of Colloid systems on changes in the boundary conditions are given. Uncertainties and unpredictabilities brought forth as the result of extrapolations of material properties to nano-scale are in addition to the description of complexities of individual chemical compositions also mentioned in this section. The requirements of sustainability assessments and a thorough comparison between biological and artificial synthetic processes, with the importance for the growing field of biomimetics, are described in Sec.6. In Sec.7, arguments in favor of the importance of providing a productive entwinement between theoretical and experimental efforts are propounded. Finally, Sec.8 provides ideas in support of the fruitful juxtaposition of the so-called topdown and bottom-up methodologies. The conclusion is that the most prosperous synthetic pathways for the coming era may be related to constructive and interdisciplinary overlapping of diverse methodological approaches to investigation and manipulation of physicochemical patterns of the sampled reality.

hydrated na2o b2o3 sio2 glass prepared by Colloid Chemistry method
Journal of Non-crystalline Solids, 2015Co-Authors: Qi Liu, Xiaoshan Wang, Hua Ruan, Zhiyu WangAbstract:Abstract In this paper, the hydrated Na2O–B2O3–SiO2 glass was prepared by Colloid Chemistry method, sodium silicate solution and boric acid as raw materials. The high viscosity transparent Na2O–B2O3–SiO2 Colloid was drawn from the solution in the course of mixing, after drying in the oven at 60–200 °C for 24 h, the hard and transparent hydrated glass was obtained. The effect of drying temperature and B2O3 content was studied. The phase composition and thermal parameters were characterized by means of X-ray diffraction and thermal analysis. It was found that the temperature of glass transition (Tg) of this kind of glass increased along with the increase of the drying temperature and the durability of this glass increased with B2O3 content. The hydrated Na2O–B2O3–SiO2 glass could be dried to give amorphous solids, so it might have broad application prospects in the lightweight thermal insulation material field.

Study on Preparation of Organic-inorganic Composite Foam Glass Thermal Insulation Materials by Colloid Chemistry Method
Bulletin of the Chinese ceramic society, 2014Co-Authors: Hu Bing-biAbstract:The novel organic-inorganic composite foam glass thermal insulation material is foamed from sol which complex with polymer through Colloid Chemistry process. Comparing with low-temperature foam glass and traditional foam glass,the organic-inorganic composite one is more uniform,it's pore diameter is smaller,percentage of closed pore is bigger. The mechanical properties are improved obviously,the compressive strength was increased to its highest of 1. 00 MPa( ωp= 8. 6%),and the elastic modulus was decreased to its lowest of 18. 33 MPa( ωp= 10. 5%). Water resistance is also improved,water absorption rate at room temperature is 4. 9%( ωp= 10. 5%) and softening coefficient is 90. 5%( ωp= 10. 5%); The strength retention rate is up to 60. 9%( ωp= 10. 5%) after 2 h hot water treatment. Pore structure, mechanical properties and water resistance of organic-inorganic composite foam glass showed that it is a porous insulation material with broad application prospects.
