Effect of interconnected molecular types on the packing rate of self-assembled monolayers of TMA-A zeolite nanocrystals on glass

김익진,Wei Zhao,Jeong Ho Chung,Marius Olarin,Alexandru F. Trandabat,Romeo-Cristian Ciobana 한양대학교 세라믹연구소 2010 Journal of Ceramic Processing Research Vol.11 No.3

Well-shaped high quality TMA-A zeolite nanocrystals were synthesized in a mother solution with a composition of Al(i-pro)3: 2.2 TEOS : 2.4 TMAOH : 0.3 NaOH : 200H2O at 90 oC for 3 days using a hydrothermal method and self-assembled monolayers coated on glass substrates by different types of covalent linkages. The average size of the zeolites used was 60~100 nm with an average lattice constant of 24.61 Å. The self-assembled monolayers of zeolite oriented with faces parallel to the glass substrates showed only planes of the forms {h 0 0} with interconnected molecules. Scanning electron microscopy (SEM) and X-ray powder diffraction (XRD) were used to characterize the synthesized crystals and self-assembly monolayers of TMA-A zeolite with the surface-bound functional groups.

Orientation-controlled self-assembled monolayers of zeolite nanocystals on glass with 4-diisocyanates as covalent linkers

김익진,Young Mi Kim 한양대학교 세라믹연구소 2010 Journal of Ceramic Processing Research Vol.11 No.1

High-quality TMA-A zeolite nonocrystals were synthesized using a hydrothermal method from a Al(i-pro)3 : 2.2 TEOS : 2.4TMAOH : 0.3 NaOH : 200H2O composition. The average size of the zeolite crystal used was 60-130 nm with a lattice constant of 12.389 Å. The well-oriented self-assembled monolayers of zeolite with a face parallel to the glass surface treated with the 4-diisocyanates (DIC-4) showed only planes of the form of {h 0 0} by covalent linkages. High resolution transmission electron microscopy (HRTEM), scanning electron microscopy (SEM), X-ray powder diffraction (XRD), and dynamic light scattering (DLS) were used to characterize the self-assembled monolayers of synthesized zeolite crystals.

프랑스 고전주의 시대에 멜랑콜리의 수용과 인식 - 문학치료적 관점에서 -

Depuis l'antiquité on voit la mélancolie par deux visages bien différents : un dégoû̂t de la vie et une source de création. D'une part, la mélancolie a été abordée sur le plan clinique, désignant une pathologie conforme à la théorie des humeurs. Il s'agit de la bile noire. D'autre part, la mélancolie est considérée comme une vertu de son potentiel idéologique. Ainsi elle entre dans un monde littéraire et artistique et s'associe au génie de l'artiste plus ou moins dépourvu. Au moyen â̂ge, elle a été considérée comme une mal satanique qui dérangeait l'homme de reconnaitre la joie et la grâ̂ce que lui avait accordées Dieu. On l'appelait cette mélancolie l'«acedia». La Renaissance voyait dans la mélancolie une humeur responsable du génie comme des errements de l'esprit. Les romantiques en faisaient l'emblème de leur poésie sentimentale et leur mode d'expression privilégié du « mal d'un siècle », pris au piège du « vague des passions ». Ils reconnaîssaient dans le thème de la mélancolie l'avènement d'un langage nouveau, nécessaire à la représentation dans les oeuvres, d'une nouvelle réalité, oppressante, vide de sens. Elle est la contrepartie de la démocratisation de l'exceptionnel, de cette quê̂te de n'ê̂tre que soi-mê̂me. Pourtant le trajet de cette maladie liée à l'émergence de l'individualisme contemporain a été déjà commencé à l'ère classique. Au travers des oeuvres des classiques comme Corneille, Racine, Molière, la mélancolie s'est servie de la source dramaturgique. Surtout le dernier, comme l'a prouvé les travaux exhausstifs de Patrick Dandrey, a parcouru la tradition dramaturgique de la mélancolie : mélancolie érotique et mélancolie hypocondriaque.

Excellent thermal shock resistant materials with low thermal expansion coefficients

김익진,Ludwig J. Gauckler 한양대학교 세라믹연구소 2008 Journal of Ceramic Processing Research Vol.9 No.3

The high performance of advanced ceramics, fuel cells, and also precision devices for semiconductor systems have been limited by the problem of thermal stresses induced by the thermal expansion between different materials. To avoid this problem, one of the choices is to develop a low or zero-level thermal expansion material, to be used, for instance in diesel particulate filter applications, in which the original dimension of the material is maintained, without being influenced by thermal shock at high temperatures. It appears that the negative thermal expansion of Al₂TiO5 ceramics are due to the effects of grain boundary microcracking caused by the large thermal expansion anisotropy of the crystal axes of the Al₂TiO5 phase. During a reheating run, the individual crystallites expand at low temperature; thus, the solid volume of the specimen expands into the micro cracks, where as the macroscopic dimensions remain mostly unchanged. As a result, the material expanded very little up to 1000 oC and the micro cracks closed at higher temperatures. This result is closely related to thermal expansion curves that were relatively steep. A characterization of the damage induced by thermal shock was conducted by measuring the evolution of the Young’s modulus using ultrasonic analysis, aided by the density and thermal expansion coefficients.

Synthesis and characterization of TMA-A zeolite nanocrystals

김익진,Young Mi Kim,Seok Ju Lee 한양대학교 세라믹연구소 2007 Journal of Ceramic Processing Research Vol.8 No.2

Well-controlled cubic nanocrystals of TMA-A zeolite with a size of 60~100 nm were synthesized by a hydrothermal method in a solution with a Al(i-pro)3: 2.2 TEOS: 2.4 TMAOH: 0.3 NaOH: 200H2O composition. The single TMA-A nanocrystals has an average lattice constant of 24.61 Å and a surface area of 742.36 m2/g. A thermal treatment of the TMA zeolite crystals resulted in their becoming amorphous above 900 oC. Environmental scanning electron microscopy (ESEM), high resolution transmission electron microscopy (HRTEM), X-ray powder diffraction (XRD), Fourier transform infrared (FT-IR) spectroscopy, and a DTA/TGA and BET analysis were used to characterize the initial materials and the products obtained after various heat treatments.

일제강점기 한반도의 기독교 탄압과 회유정책

김익진 그리스도신학대학교 출판부 2010 교수논문집 Vol.10 No.-

This paper is to probe the process on giving hard time to Christianity and missionaries in Korean Peninsula which was under Japanese rule. The ministry and mission work was restricted by Japanese in three ways which were nonintervention policy, appeasement policy on missionaries, and Chosun evangelism policy. The Korean historians evaluate the activity of missionaries under Japanese rule in separate way which is either positive or negative. In general history, missionaries were seen as an agent of imperialism. Therefore, historians usually evaluate them in negative way. They think missionaries in Korea had maintained the fraternity with Japan and even cooperated with Japan in the way of leading Korean church not to participate on the resist-Japanese movement. On the other hand, Korean Christian historians have argued that missionaries had contributed to the resist-Japanese movement not only through evangelism but also through education in a way of awakening the consciousness of Korean people who eventually led Christians to have interest in the society as well as the nation. In this paper, the writer focus on the three policies to Christianity and missionaries under Japanese rule. First, the nonintervention policy of U.S.A. and mission headquarter- When Japan win the war, U.S.A. government directed strongly to the legation as well as American citizens living in Korea including missionaries not to intervene in Chosun’s political situation because they concerned about the relationship with Japan. Second, Japan’s appeasement policy on missionaries-Ito’s appeasement policy on missionaries Japan’s domestic public sentiment saw missionaries as obstacle of its rule over Korea and gradually make them to be withdrew. However, Ito preferred the conciliation with missionaries so that they justify their occupation by force on Korea as well as stopping and breaking off the Korean resistance. Third, Chosun evangelism of Japanese Church - They planned for Japanese Christian to influence Korean church in weakening and debilitating and eventually merging Korean church into Japanese church.
