  • Photoinduced phase transition between vesicles and coacervates using low-molecular-weight catanionic amphiphiles

    Kojima T., Terasaka K., Asakura K., Banno T.

    Colloids and Surfaces A: Physicochemical and Engineering Aspects (Colloids and Surfaces A: Physicochemical and Engineering Aspects)  669 2023.07

    ISSN  09277757

     View Summary

    Amphiphiles form various molecular self-assemblies in the aqueous phase, such as vesicles and coacervates, depending on molecular properties. Recently, phase transitions between vesicles and coacervates have drawn much attention because the switching between “closed” and “open” compartments could achieve the controllability of molecular sequestrations. We expect that the photoinduced drastic change in the molecular structure of catanionic amphiphiles comprising azobenzene-containing cationic amphiphiles (Azo) and anionic sodium dodecyl sulfate causes the transition. Self-assemblies prepared by a thin-film hydration method were observed using microscopy under UV and subsequent visible-light illumination. Additionally, investigation of selectivity for molecular sequestration and assay of enzymatic reactions in the self-assemblies were conducted. Photoinduced reversible phase transitions between vesicles and coacervates occurred owing to the photoisomerization of Azo. The formed coacervates had selectivity for molecular sequestration. Additionally, the transition achieved fusion of different vesicles via coacervates. Although coacervates are generally known to facilitate enzymatic reactions, the reactions were inhibited in the presence of the formed self-assemblies due to the deactivation of enzymes. Our results represent rapid and non-invasive systems of reversible vesicle–coacervate transitions. Furthermore, the findings provide a new aspect of coacervates in which catanionic low-molecular-weight amphiphiles could act as suppressors of chemical reactions.

  • Ultrafine bubble generation by rapid condensation of mixed vapor of non-condensable gas and steam

    Terasaka K., Taguchi K., Tetsuka T., Fujioka S.

    Chemical Engineering Science (Chemical Engineering Science)  263 2022.12

    ISSN  00092509

     View Summary

    Although the mechanism of ultrafine bubble generation has not yet been elucidated, we believe that the state of gas-saturated water before the generation of ultrafine bubbles is the most important factor in the mechanism of ultrafine bubble generation. Therefore, we proposed the hypothesis that the spatial distribution of dissolved gas molecules among the water molecules before the ultrafine bubble formation is stared has a significant effect on the formation of ultrafine bubble suspending water. Based on this hypothesis, we succeeded in generating ultrafine bubbles of sufficient number concentration in the condensate by rapidly condensing a well mixture of non-condensable gas and vapor by cooling. The number concentration of the generated ultrafine bubbles increased almost in proportion to the condensation rate of the vapor. Therefore, it was found that promoting the formation of bubble nuclei from dissolved gas molecules existing between water molecules in the condensate and suppressing bubble growth led to an increase in the number concentration of ultrafine bubbles. The principle of ultrafine bubble generation in this invention not only simplifies the generation of ultrafine bubble water but also enables the control of the number concentration of ultrafine bubbles in water.

  • Enhanced enzyme stability and gas utilization by microbubble aeration applying microporous aerators

    Catalysis Science & Technology (The Royal Society of Chemistry)  13 ( 4 ) 1098 - 1110 2022.12

    Research paper (scientific journal),  ISSN  20444753

     View Summary

    During the optimization of processes in biocatalysis, the limitations of mass transfer and enzyme stability have to be overcome. To achieve these goals, aeration with microbubbles is advantageous by providing favorable properties, which include high gas utility, low-pressure drop, and reduced foam formation. In this study, the influences of microbubble, classic sub-millibubble and macrobubble aeration on enzyme stability and gas utility are compared. Using five enzymes, the half-life was investigated by comparing the microbubble aeration with a 2 μm porous sintered frit to the macrobubble aeration with a 5 mm open pipe, both adjusted to provide a constant kLa of 160 h−1. Furthermore, the half-life of a glucose oxidase was investigated by variation of the kLa in the range of 40 to 350 h−1 and the mode of the aeration system comparing the 2 μm and 10 μm sintered frit as well as the 5 mm open pipe. In both experimental set-ups, it was demonstrated that the aeration with microbubbles using the 2 μm sintered frit was beneficial for reaching high levels of enzyme stability. From this, we discovered that the interfacial area renewal rate plays an important role in the process of enzyme deactivation, which changes depending on the aeration mode.
