  • Refereed, Journal of Physics: Conference Series, IOP Publishing, Experimental and Theoretical Studies on the Self-assembled Nano-structure of Nonionic Surfactant/ionic Liquid Hybrid Systems, Jingjing Zhu; Er Hua; Masafumi Harada, Abstract

    The self-assembled structure of various Brij series nonionic surfactants (such as Brij-30, Brij-52, Brij-56, Brij-58, Brij-35, and Brij-700) hybridized with room-temperature ionic liquids (RTILs) was studied using small-angle X-ray scattering (SAXS) measurements and DFT calculations. The detailed characterization of the obtained self-assembled structure in nonionic surfactant/RTILs hybrid system was carried out using the combination of SAXS and DFT calculations. The SAXS result indicates that the alkyl chain length dependence on the spatial correlation corresponds to the interference peak angle. The addition of Brij surfactant to the [BMIm][PF6] results in a drastic change in the interference peak position. The DFT calculation result shows that a weak hydrogen bonding was formed between the −CH, −F of RTILs ([BMIm][PF6] and [OMIm][PF6]) and the polar site −OH, −O − of surfactants (Brij-30 and Brij-56). When the mixing molar ratio of ILs/Brij is 1:1, the absolute value of interaction energy (ΔE0BSSE) is 8.10-1.43 and 4.22-0.90 kcal·mol-1 for ILs/Brij-30 and ILs/Brij-56, respectively. Meanwhile, in the case of the ILs/Brij molar ratio equal to 2:1, ΔE0BSSE is 19.14-1.79 and 12.39-1.45 kcal·mol-1, respectively. It suggests that the stability of ILs/Brij hybridized system is higher for ILs/Brij-30 than for ILs/Brij56, and it has an increasing tendency to some extent with an increase of the molar fraction of ILs., 01 Oct. 2023, 2610, 1, 012064, 012064, International conference proceedings, 10.1088/1742-6596/2610/1/012064

  • Refereed, Langmuir, American Chemical Society (ACS), Combined Small-Angle Neutron Scattering/Small-Angle X-ray Scattering Analysis for the Characterization of Silver Nanoparticles Prepared via Photoreduction in Water-in-Oil Microemulsions, Masafumi Harada; Miho Yamamoto; Hiroki Iwase, In this study, we used small-angle neutron scattering (SANS) and small-angle X-ray scattering (SAXS) to investigate the formation process of silver (Ag) nanoparticles (NPs) in water-in-oil (w/o) reverse microemulsions comprising sodium bis(2-ethylhexyl) sulfosuccinate (AOT), water, and organic solvents (such as benzene, octane, and decane) by the photoreduction of silver perchlorate (AgClO4). Combining SANS and SAXS, the structural changes in the w/o microemulsions before and after the formation of Ag NPs via photoreduction were quantitatively evaluated. From the SANS experiments performed using the contrast-variation method, the size of water cores containing Ag NPs and the thickness of the AOT shells were calculated using the core-shell hard-sphere model. The size of the Ag NPs and their aggregates was calculated via SAXS analysis based on the polydisperse sphere model with a Schulz-Zimm distribution. We found that aggregates of three or four primary Ag NPs are formed by, first, the aggregation of water droplets through the entanglement of the tails of the AOT shell, followed by the self-assembly of Ag NPs into their aggregates because of particle-particle attractive interactions., 29 Oct. 2021, 37, 44, 13085, 13098, Scientific journal, True, 10.1021/acs.langmuir.1c02235

  • Refereed, Journal of home economics of Japan, Dry-Cleaning Washing Systems Using Liquid CO2 and Their Detergency for Various Artificially Soiled Fabrics., HARADA Masafumi; Masafumi HARADA, Commercially available dry-cleaning solvents, such as hydrocarbon from petroleum distillates (aromatic, paraffin, naphthene) and tetrachloroethylene (perc), have done serious damages to our environment. In order to overcome these environmental problems, we have developed dry-cleaning washing systems for textile articles with liquid CO_2 as a substitute solvent. Liquid CO_2 is well known to be a greatly promising solvent because it is inexpensive, nontoxic and nonflammable. In this study, cleanings of some artificially soiled fabrics using both liquid CO_2 in high pressure equipment and aqueous surfactant solutions in H_2O and organic solvent (AK-225), with mechanical force by means of a magnetic stirrer, have been carried out to estimate and compare their detergencies obtained from reflectance measurements. As a result, the cleaning of oil stains made with motor oil with liquid CO_2 has a detersive efficiency of about 44%. The detergency increases with the addition of AOT, while it decreases with the addition of PEG. This increase of detergency with the addition of AOT might be due to the formation of O/W emulsions composed of a large amount of AOT in the mixture of liquid CO_2 and water, because the solubility of AOT is higher in water than in liquid CO_2, and thus CO_2 droplets in the water phase would be able to encapsulate oil stains such as those caused by motor oil. On the other hand, in the case of cleanings of water-soluble stains (coffee, red wine, etc.) using liquid CO_2, the detergency remarkably increases, even with the addition of small amounts of aqueous surfactant solutions to liquid CO_2., 2005, 56, 4, 241-253, 253

Spinel ferrite nanoparticles have been synthesized by microwave irradiation, and their structural and magnetic properties have been investigated by using XRD, XPS, HRTEM, EELS, EXAFS, and SQUID measurements. Furthermore, since the particular properties of ferrite nanoparticles are strictly related to the distribution of cations between octahedral and tetrahedral sites in the spinel structure, EXAFS measurements have been used to determine quantitatively the distribution of cations in the nanoparticle., kaken

The fine structures of the metal complexes in the PILs have been clarified using VIS absorption spectra, NMR relaxations, and EXAFS. It has been revealed that the present PILs are characteristic to encapsulate Lewis acids such as trnasition-metal ions. On the basis of the studies on the interactions with trnasition-metal ions, it has been revealed that the present PILs are advantageous to trap and then release CO2 gas. Furthermore, an effect of the present PILs on the redox behavior of copper(II) ions in imidazolium IL system has been studied., kaken

  • Grant-in-Aid for Scientific Research (C), 2005 - 2007, 17550059, Luminescence Properties of Liquid Crystals and Molecular Glasses Comprising Rare Metal Complexes with Long Alklyl-Chains, IDA Masayasu; HARADA Masafumi, Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research, Nara Women's University, 3250000, 3100000, 150000, Molecular glasses (glassy states comprising low molecular-weight compounds) are regarded as functional materials for molecular design and characterization in comparison with macromolecular glasses. Particularly, molecular glasses of metal complexes have many advantageous features as functional materials due to various reactivities and structures, whereas studies on such systems have been rarely reported. Our research group has found that the acylaminocarboxylate-lanthanide (III) complexes readily form glassy states by an evaporation of solvents from solutions. The present categories of metal complexes seem to have a beneficial feature for a systematic study concerning the relationship between the molecular structure and the extent of the ordering of the molecular aggregation.
    Our project is composed of the following three parts. 1) Formation of glassy states of octanoylalaninate complexes of yttrium, lanthanum, and calcium and the aggregation behavior in methanol and chloroform. 2) Analogous studies for europium(III) and terbium(III) complexes relating with the luminescent properties. 3) Formation of ionic liquids comprising of silver alkylethylenediamine complexes. Although the last subject does not seem to be directly related with the present project, the mysterious state of ionic liquids has been recently clarified to be closely correlated with the formation of molecular glassy. In the subjects of 1) and 2), the glassy states were characterized using DSC, TG-DTA, WAXS, SAXS, solid-state NMR spectroscopy, and EXAFS. The structures in the solid states were related with concentrated solutions whose properties were studied by NMR, SAXS, and EXAFS, and the process of the glassy formation from the concentrated solutions was revealed. The glassy state was understood as a result of isotropic aggregation in solution. The luminescent properties of the europium and tedium complexes were appropriate probes for monitoring the aggregation process and could be related with the results of NMR studies. It is remarkable that the europium and lanthanum complexes having phenylalaninate and serinate headgroups showed a novel liquid-crystalline glassy state., kaken
