今年度は、昨年度検討が不十分であった、様々な操作条件が粒子の集団運動に与える影響に関する実験的検討を引き続き遂行した。具体的には、まず、触媒粒子の個数濃度を変化させ、集団運動を行う最適な濃度条件を検討した。さらに、６種類の有機燃料（エタノール，アセトアルデヒド，メタノール，2-プロパノール，1-プロパノール，エチレングリコール）の濃度を変化させることで、実験条件によって、界面が丸みを帯びたクラスターを形成したり、界面が角ばったクラスターを形成したりといった、特徴的な集団運動パターンが発現することがわかった。 また、発展的な研究として、本触媒反応において限定反応物質である溶存酸素を生成する過酸化水素を混合することで、溶存酸素を持続的に供給可能なシステムを構築し、触媒粒子の集団⇔解散が周期的に起こる新規な集団運動パターンを見出した。集団運動の持続時間を自在に制御できる可能性がある点で有用な知見であるといえる。 さらに、理論的な検討として、反応拡散過程を組み込んだ触媒粒子の集団運動を再現できる数理モデルの構築に着手している。本モデルでは、初期条件として空間的に濃度揺らぎのある触媒粒子が限定反応物質である溶存酸素を消費し、それにより生じる酸素濃度勾配を駆動力として自走する一次元のシンプルなモデルであり、触媒粒子が集団化し、溶存酸素が消費され尽くすと粒子のブラウン運動によって解散していく挙動が再現できた。, Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research, 2020/04 -2024/03, Grant-in-Aid for Scientific Research (B), Doshisha University - マイクロ空間動力としての自己運動系の研究

1. Formation mechanism of nano-size unit structure 1-1 Formation mechanism of nano-size silica structure Various morphologies of microstructure were synthesized by pH variation in silica nano-structure formation by templating mechanism in laurylamine hydrochloride/tetraethoxysilane system. Integrated ordered structure such as hexagonal array was formed in the narrow pH region from 10 to 11.5. 1-2 Formation mechanism of titania anotubes Highly photocatalytic single crystalline anatase titania nanotubes can be synthesized by templating mechanism in laurylamine hydrochloride/tetraisopropylorthotitanate modified with acetylacetone. Titania nanotubes were synthesized as amorphous phase and were crystallized in the rection process at 80 ℃ for 3days. The pore-size became large with proceeding crystallization. 2. Elucidation of formation mechanism of the integrated ordered structure of silica Liquid-liquid interface between the organic and aqueous phases played an essential role for the formation of integrated ordered structure of silica at pH 10 to 11.5. The formation processes of integrated ordered structure in a few minutes at pH 10.5 were measured in every second by small angle X-ray scattering using syncrotron orbit radiation high power X-ray at SPring 8. We found that independent cylinders were formed first at the liquid-liquid interface and gathered with each other on the two-dimensional space of the interface to make an two- and three-dimensional integrated ordered structure., Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research, 2000 -2001, Grant-in-Aid for Scientific Research (C), KYOTO UNIVERSITY - Control and Design of Nano-Materials Produced with the Help of Amphiphilic Molecules Assemblies
HARADA Makoto; SHIOI Akihisa; ADACHI Motonari
We elucidated the formation processes and the control method of the microstructures in nano-meso materials, which were prepared using self-organized assemblies of amphiphilic molecules. 1) Nano-meso porous materials : We elucidated the microstructure formation processes in silicon alkoxide(TEOS)/surfactant(laurylamine) composite systems. In acidic aqueous solution, nano-meso network structure composed of silica rods is formed, and in neutral aqueous solution, aerogel-like silica structure is obtained. Whereas in alkaline aqueous solution, cylinder-hexagonal and/or cubic ordered structures of silica can be prepared. The rate-ratio of TEOS-hydrolysis to condensation reaction plays an important role in the formation of these different microstructures. The structure formation at the microstructure interface is also important for the ordered structures. We elucidated the effect of the microstructure interface on the TEOS hydrolysis using reversed micellar system. Based on these results, we succeeded in the preparation of very long silica-tubules with nanometer diameter. 2) Bicontinuous nano-materials of polymers : The structure of reversed micelles was elucidated in the systems composed of ionic surfactants and the polymers with reverse electric charge. This result provides some information on designing bicontinuous materials. We also succeeded in the preparation of bicontinuous polymer materials with hydrophilic passes using hexagonal structure of ionic surfactant as the template. 3) Nano-particle materials with two-dimensional array : We focused on the preparation of nano-particles and the control of the size-distribution of the obtained particles, which can be used for two-dimensional array. Systematic studies were performed for the growth processes of CdS- and Au-nanoparticles in reversed micellar solution. Using the results, we succeeded in the preparation of nano-particles with sharp size-distribution., Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research, 1996 -1998, Grant-in-Aid for Scientific Research (B), KYOTO UNIVERSITY - 両親媒性分子集合体中における化学反応誘起型構造形成に関する研究
基盤研究（Ｃ）（一般）, 1997 -1997, Competitive research funding - 高分子/界面活性剤分子集合体混合系における集合体構造・物性の制御設計
塩井 章久
本年度の研究は、マイクロエマルション/人工高分子系とマイクロエマルション/タンパク質系の2系統で行った。人工高分子系では、高分子としてポリアクリルアミド(PAM)、ポリアクリル酸(PAA)、ポリアリルアミン(PAN)の3種類を用い、界面活性剤としてはAerosol-OT(AOT)を用いた。AOTを含んだ有機溶液に、所定濃度の高分子水溶液を注入することでマイクロエマルションを作成し、その溶液の粘度およびx線小角散乱SAXSを計測した。その結果、高分子の種類によらず粘度はAOT濃度が0.3M程度まで高分子の影響を受けないことが分かった。しかし、水とAOTのモル比が小さいときには、AOT濃度を0.5M程度以上にすると高分子の添加により粘度が数倍上昇し、その上昇の程度は高分子の種類や分子量によって大きな影響は受けなかった。SAXSの結果からは、PAN系のみ組織形態がAOTのみのときの球から変化し、円筒状になった。このような場合は、円筒の充填が密なとき(AOT濃度が高いとき)に粘度が上昇することは容易に理解できる。しかし、PAA、PAMの系では、SAXSに顕著な高分子の影響は見られず、上記条件での粘度の急激な上昇は、組織間の近接相互作用が高分子の影響で変化するのではないかと想像されるが、詳細は不明である。組織形状に対するPANの特異性は、PANがカチオン性の高分子であることが原因と思われる。タンパク質系では、非イオン性界面活性剤からなるマイクロエマルションがタンパク質に対して変性などの影響与えないことを明らかとした。この結果は、マイクロエマルションによるタンパク質の分離や酵素反応に対して、大きな利点であると考えられる。そこで、幾種類かのタンパク質について、タンパク質のマイクロエマルションへの抽出、及び、マイクロエマルション系での酵素反応実験を遂行した。その結果、非イオン性界面活性剤系はタンパク質の抽出に対しては、タンパク質の変性を防ぎ、また場合によっては分離の選択性を強く高めることがわかった。さらに、非イオン性界面活性剤系では、これまでのAOT系に対して、かなり高い酵素活性を示すことを明かとした。, 日本学術振興会, 科学研究費助成事業, 1995 -1995, 奨励研究(A), 京都大学 - W/Oマイクロエマルションの組織形状,同溶液物性の制御・設計に関する研究
塩井 章久
本研究では、W/Oマイクロエマルションの微細組織構造及び、それらを含む溶液の巨視的な物性を制御することを目的とした。まず、界面活性剤分子形と微細組織形状との関係を明らかとするモデルを提案した。それによって、親水基/疎水基長の比、疎水基中での疎水基セグメントの重点密度が本質的であることを見いだした。また、添加電解質濃度が微細構造に与える影響も明確とした。このモデルに基づいて、エアロゾルOT(AOT)以外に、ジオレイルリン酸ナトリウム、ジトリデシルスルホコハク酸ナトリウム、が球状組織形成系でありジ2エチルヘキシルリン酸ナトリウムSDEHPが円筒組織形成系であることを見いだした。さらに、ノニオン界面活性剤やイオン性界面活性剤間の混合系の微細組織構造についても実験的検討を加えた。つぎに球状組織系としての代表であるAOTと円筒組織系の代表であるSDEHPを用いて、界面活性剤濃度がかなり濃厚な状態まで、浸透圧縮率、粘弾性測定、電気伝導度測定、動的構造因子の計測を行った。その結果、球状組織系では、基本的には剛体球流体系として単純流体の液体論で溶液物性の記述が可能であることがわかった。一方、円筒組織形成系では、円筒が絡まりあうことでネットワークを形成し、擬高分子組織を形成するとして、高分子溶液論の枠組みを用いることで、溶液物性の半定量的な理解が可能であることが分かった。これら液体論並びに高分子溶液論は、非経験的に、溶液の浸透圧、粘弾性等をある程度予測する能力を有している。上記のことは、我々のモデルによって界面活性剤分子形から、微細組織構造の制御設計が可能であり、そのような組織を含む溶液物性を論理的に予測できるということを意味する。これは、界面活性剤分子形から微細組織・溶液物性の目的に応じた設計ができるということを意味し、申請段階での目的は達成できたと考えている。, 日本学術振興会, 科学研究費助成事業, 1994 -1994, 奨励研究(A), 京都大学 - Advancement of the Functions of Molecular Assemblies Composed of Amphiphilic Molesules

Functions of unit molecular assembly : We elucidated the fundamental items for advancing the functions of unit assembly ; (1) theoretical model relating the surfactant molecular form with the geometry of the assembly, (2) the behaviors of the surfactant systems yielding spherical and cylindrical assemblies, (3) the characteristics of the solubilization of guest molecules into the host assemblies, (4) the characteristics of the assemblies in non-ionic surfactant systems and in non-ionic and anionic mixed surfactant systems, and (5) the roles of the assemblies in the preparation of CdS fine particles. 2. Functions of surfactant/protein systems : We elucidated the driving force for solubilizing proteins in the assemblies and the solubilization dynamics of guest molecules. Based on these, we proposed the methods of tailoring molecular assemblies for protein solubilization and selective separation of proteins without denaturation of proteins. The methods are based on regulating the electrostatic and affinity interactions between proteins and surfactants. 3. Functions of concentrated assembly systems : We elucidated the static and dynamic characteristics both of the spherical assembly system composed of concentrated Aerosol-OT and of the network micro-structures in concentrated sodium bis (2ethylhexyl) phosphate system. We also obtained fundamental information on the solidification of nano-structures in microemulsions., Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research, 1993 -1994, Grant-in-Aid for General Scientific Research (B), KYOTO UNIVERSITY - Research on design of organized assemblies composed of amphiphilic molecules

This work aims at elucidating how the microemulsions of reverse type affect the protein extraction and the chemical reactions such as ultra-fine particle formation, and how the microemulsions should be designed for these practical applications. The requits obtained are as follows : 1. Separation of matter by W/0-microemulsion : Several amino acids are solubilized in flicroemulgion globules through the electrostatic interaction, and hydrophobic amino acids are entrapped on the interfacial zone of the microemulsion globules. Cytochrome c, which is denaturalized by adsorbing the surfactant molecules, is solubilized on the interfacial zone of the microemulsion globules. There exist two processes, fast and slow processes, in the protein solubilization. The denaturalized protein can be converted to native state, when cytochrome c is extracted and back-extracted in short term. 2. Production of ultra-fine particles : The extraction processes of metal ion from an aqueous phase to the organic phase with microemulsion are quite different from those in microemulsion-free case. The rate of the reaction to yield the metal complex and the formation constant for the complex strongly increase in the presence of the microemulsion, because both metal complex and the reactants are concentrated near the interface of a microemulsion globule. The microemulsion contributes to the formation of monodisperse ultra-fine particles of gold. 3. Design of organized assemblies : Cylindrical and disklike microstructures are formed in the systems containing the sodium salts of organs-phosphoric acids. The shape and the size of the assemblies determine the characteristics of the system. Based on this result, it was shown from both experimental and theoretical view points how the key factors (the surfactant molecular forms, the species of solvent, and the salinity condition) affect the behaviors of the microeliulsions. Finally, we present a model for designing and controlling the microemulsion., Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research, 1990 -1991, Grant-in-Aid for General Scientific Research (B), Kyoto University - Selection of Solvents and Their Diluents for Solvent Extraction of Metals

This research is concerned with elucidating the basic concept of selecting the solvents and their diluents for metal extraction with chelating agents, from the view points of kinetics and equilibrium. Metal extraction with microemulsion is also studied for providing alternative separation field for metal extraction. The results obtained are as follows: 1)the reaction between the 1:1 metal complex absorbed on the interface and the solvent dissolved in the aqueous phase determines the rates of metal extraction with chelating agents of commercial use. Three factors,i.e., the partition of the solvent between the aqueous and the organic phases, the adsorption process of the solvent on the interface, and the equilibrium constant of proton dissociation of the solvent are important for the optimal choice of the solvents and diluents. The solvent of commercial use has interfacial activity in nature, and the adsorption process is less important than the other two factors. 2)The chain length of the hydrocarbon group in a chelating agent molecule has an effect on the partition coefficient,which is different from that for acidic organophosphorous compunds. Then, an approach based on quantum chemistry is needed for obtaining the basis of solvent and its diluent selection. 3) It was shown that the metal separation with the aid of microemulsion is feasible. The metal extraction equilibrium for this system is determined by the Coulomb interaction. Thermodynamic analysis was also carried out for controlling the size of the microemulsion droplets with salinity for the aqueous phase. We are now planning the researches on the stability of the organized assemblies composed of amphiphilic agents and the phase diagrams concerned with this assemblies., Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research, 1986 -1988, Grant-in-Aid for General Scientific Research (C), Kyoto University - ゲル中の反応拡散を利用した構造性微粒子の分別製造
