    固体と液体の界面をナノ・分子スケールから正しく理解することは,熱工学・流体工学など機械工学の根幹分野における基礎的知見として切望されている.近年,固液界面にはナノバブルと呼ばれる小さな気泡や,さらに平坦で薄い気体分子の吸着層が存在しており,種々の界面現象と関連していることが報告されている.一方,それら気相には依然として未解明な性質が多く,精緻な界面計測による詳細な理解が望まれている.本研究では原子間力顕微鏡を用いて固液界面ナノバブルと気体分子吸着層を正確に計測する手法を確立し,それらの気相が固液界面でどのように共存しており,温度変化に対してどのように応答するかを世界で初めて明らかにした.

  • Precursor-Film-Mediated Thermocapillary Motion of Low-Surface-Tension Microdroplets

    In contrast to microdroplet condensation with high contact angles, the one with low contact angles remains unclear. In this study, we investigated dynamics of microdroplet condensation of low-surface-tension liquids on two flat substrate surfaces by using reflection interference confocal microscopy. Spontaneous migration toward relatively larger droplets was first observed for the microdroplets nucleated on the hydrophilic quartz surface. The moving microdroplets showed a contact angle hysteresis of a0.5°, which is much lower than the values observed on typical flat substrates and is within the range observed on slippery lubricant-infused porous surfaces. Because the microdroplets on the hydrophobic polydimethylsiloxane surface did not move, we concluded that the ultrathin precursor film is formed only on the hydrophilic surface, which reduces a resistive force to migration. Also, reduced size of droplets promotes the thermocapillary motion, which is induced by a gradient in local temperature inside a small microdroplet arising due to the difference in size of adjacent droplets.

  • Adsorbed gas layers limit the mobility of micropancakes

    In contrast to surface nanobubbles, the properties of atomically flat gas phases such as micropancakes remain unclear. In this study, we investigated nanoscopic gas phases existing at the interface between highly ordered pyrolytic graphite and air-supersaturated pure water using high-sensitivity frequency-modulation atomic force microscopy (AFM). Micropancakes appeared on a disordered gas layer overlying an ordered gas layer and moved in the direction of AFM scanning. Their movement stopped at the edge of the disordered gas layers, whereas the two gas layers did not move at all. The limited mobility of micropancakes is explained by assuming that the disordered and ordered gas layers, which are composed of strongly adsorbed gas molecules, behave like solid surfaces, and that the surface heterogeneity between them results in a pinning effect.

  • Nanoscale pinning effect evaluated from deformed nanobubbles

    Classical thermodynamics theory predicts that nanosized bubbles should disappear in a few hundred microseconds. The surprisingly long lifetime and stability of nanobubbles are therefore interesting research subjects. It has been proposed that the stability of nanobubbles arises through pinning of the three-phase contact line, which results from intrinsic nanoscale geometrical and chemical heterogeneities of the substrate. However, a definitive explanation of nanobubble stability is still lacking. In this work, we examined the stability mechanism by introducing a "pinning force." We investigated nanobubbles at a highly ordered pyrolytic graphite/pure water interface by peak force quantitative nano-mechanical mapping and estimated the pinning force and determined its maximum value. We then observed the shape of shrinking nanobubbles. Because the diameter of the shrinking nanobubbles was pinned, the height decreased and the contact angle increased. This phenomenon implies that the stability results from the pinning force, which flattens the bubble through the pinned three-phase contact line and prevents the Laplace pressure from increasing. The pinning force can also explain the metastability of coalesced nanobubbles, which have two semispherical parts that are joined to form a dumbbell-like shape. The pinning force of the semispherical parts was stronger than that of the joint region. This result demonstrates that the contact line of the semispherical parts is pinned strongly to keep the dumbbell-like shape. Furthermore, we proposed a nanobubble generation mechanism for the solvent-exchange method and explained why the pinning force of large nanobubbles was not initially at its maximum value, as it was for small nanobubbles.

  • Impact of Sub-Nanoscale Surface Topography on Contact Line Profile: Insights from Coherence Scanning Interferometry Reviewed International coauthorship International journal

    Despite the importance of the effect of subnanoscale roughness on contact line behavior, it is difficult to directly observe the local behavior of contact lines at the micro- and nanoscale, leaving significant gaps in our current understanding. In this research, we investigate contact line motions and their relationship with nanoscale surface topography using coherence scanning interferometry. Our experiments were conducted on the substrates with different wettability without changing nanoscale surface topography. Titanium dioxide was used as a substrate, the wettability of which was varied under UV-light irradiation. A ridge-like structure with a height of approximately 1 nm was observed to cause contact line deformation toward the droplet side, regardless of the direction of the contact line motion. This was explained in terms of an imbalance in the local capillary pressure at the nanoscale contact line. We also found that the deformation becomes larger on the more hydrophilic surface, which was rationalized by theoretical prediction based on analysis of the work done by the force acting on the contact line and the change in surface free energy associated with the deformation of the liquid/gas interface. Furthermore, it was revealed by contact angle measurements that the maximum pinning forces on a hydrophilic surface were less than half of those on a hydrophobic surface. We attributed the weak pinning force on the hydrophilic surface to cascading depinning, where the initial depinning event triggers a chain reaction of subsequent depinning events, driven by the conversion of excess surface energy to kinetic energy. Our experimental works provide new insights of the relationship between the subnanoscale surface roughness and macroscopic contact line motion.

  • Temperature-dependent water slip flow combined with capillary evaporation in graphene nanochannels Reviewed

    The discovery of ultrafast water flow in graphene channels holds significant implications for various applications like electronics cooling, thermally driven energy harvesting, and solar-driven desalination. However, existing slip flow measurements on graphene are confined to room temperature, limiting our understanding of temperature-dependent behaviors and constraining potential thermal applications. Here, we simultaneously measured water slip lengths and evaporation fluxes in graphene nanochannels with depths ranging from 78 to 290 nm, spanning a temperature range from room temperature up to 85 °C. This was achieved by employing a capillary flow model combined with evaporation, a factor that cannot be disregarded at elevated temperatures. The measured water slip lengths ranged from 20 nm to 80 nm, exhibiting a decrease with increasing temperature and an increase with greater channel depths. The temperature-dependent slip length can be attributed to enhanced momentum transfer at the solid-liquid interface at elevated temperatures, while the observed channel depth dependence may result from stronger electrical-double-layer interactions with decreased channel depths. Additionally, the capillary evaporation fluxes increased with rising temperatures and greater channel depths, effectively explained by the capillary evaporation theory.

    We report for the first time a zigzag-shaped gas phase at a highly-ordered pyrolytic graphite/water interface. The novel shape of the gaseous domain is triggered by the holes of the underlying solid-like layers, which are composed of air molecules. Specifically, many holes were created by heating in the thin solid-like layers, which roughened them. The gas domains that formed on these layers deformed from circular to zigzag-shaped as the contact lines expanded while avoiding the holes of the underlying layers. We explained the formation and growth processes of these gas structures in terms of thin film growth, which varies with the mobility of the constituent molecules. This journal is

    Hydration structures are ubiquitous at solid/liquid interfaces and play a key role in various physicochemical and biological phenomena. Recently, it has been reported that dissolved gas molecules attracted to hydrophobic surfaces form adsorbed gas layers. Although a hydration structure and adsorbed gas layers coexist on the surface, the relationships between them remain unknown. In this study, we investigated a highly ordered pyrolytic graphite/pure water interface with and without adsorbed gas layers using frequency-modulation atomic force microscopy. We penetrated the adsorbed gas layers with the strong load force of the AFM tip and thereby obtained the frequency shift curves inside them. By comparing the curves with those measured on a bare HOPG surface, we found that the adsorbed gas layers were located at regions where the molecular density of water was low and were sandwiched between hydration layers with high water density. Moreover, the distance between adjacent hydration layers was larger than that predicted by simulations and was the same with and without the adsorbed gas layers. We propose that gas molecules on the hydrophobic surface interact with the hydration structure before forming the adsorbed gas layers, and extend the distance between hydration layers.

    Graphene liquid cells provide the highest possible spatial resolution for liquid-phase transmission electron microscopy. Here, in graphene liquid cells (GLCs), we studied the nanoscale dynamics of bubbles induced by controllable damage in graphene. The extent of damage depended on the electron dose rate and the presence of bubbles in the cell. After graphene was damaged, air leaked from the bubbles into the water. We also observed the unexpected directional nucleation of new bubbles, which is beyond the explanation of conventional diffusion theory. We attributed this to the effect of nanoscale confinement. These findings provide new insights into complex fluid phenomena under nanoscale confinement.

  • Wettability of AFM tip influences the profile of interfacial nanobubbles

    To accurately characterize the shape of interfacial nanobubbles using atomic force microscopy (AFM), we investigated the effect of wettability of the AFM tip while operating in the peak force tapping (PFT) mode. The AFM tips were made hydrophobic and hydrophilic by Teflon AF coating and oxygen plasma treatment, respectively. It was found that the measured base radius of nanobubbles differed between AFM height images and adhesion images, and that this difference depended on the tip wettability. The force curves obtained during the measurements were also different depending on the wettability, especially in the range of the tip/nanobubble interaction and in the magnitude of the maximum attractive force in the retraction period. The difference suggests that hydrophobic tips penetrate the gas/liquid interface of the nanobubbles, with the three phase contact line being pinned on the tip surface; hydrophilic tips on the other hand do not penetrate the interface. We then quantitatively estimated the pinning position and recalculated the true profiles of the nanobubbles by comparing the height images and adhesion images. As the AFM tip was made more hydrophilic, the penetration depth decreased and eventually approached zero. This result suggests that the PFT measurement using a hydrophilic tip is vital for the acquisition of reliable nanobubble profiles.

    As the system size decreases to the nanoscale, fluids show unique behavior because the forces derived from interfaces and three-phase contact line become dominant. Fortunately, recent advancements in measurement techniques have allowed for direct observation of fluids at the nanoscale. In this talk, we report our recent progress on experimental investigation of solid-liquid interfacial phenomena by using optical microscopy, atomic force microscopy (AFM) and transmission electron microscopy (TEM). Condensation of ethanol microdroplets was observed using reflection interference contrast microscopy. Our results showed that only when using the hydrophilic substrate, the microdroplets spontaneously moved towards the relatively larger droplet with a contact angle hysteresis as low as ~0.5°. This is due to the existence of precursor film less than 20 nm thickness near the three-phase contact lines, which reduces the resistive force against the thermocapillary motion [1]. TEM is a promising technique for observing the dynamics of interfacial phenomena with sub-nanometer spatial resolution, and we utilized liquid cell electron microscopy. For example, we found that the contact lines of nanobubbles trapped in the two graphene layers are pinned by contamination in two different ways: direct contact and non-direct contact. This mechanism was explained by the Derjaguin, Landau, Verwey, and Overbeek theory and nanoconfinement effect [2]. On the other hand, AFM is the sole technique that enables simultaneous three-dimensional observation of the liquid-gas interface and solid surface topography at the nanoscale. Glycerol nanodroplets on an ideally homogeneous graphene surface exhibit the same contact angles as those in macroscale, whereas size-dependent contact angles were observed on a SiO2 surface with angstrom-scale heterogeneity, suggesting a breakage of Young’s equation [3]. In water, high-sensitivity frequency modulation AFM revealed that dissolved gases strongly adsorb onto graphene-water interfaces, forming molecular-thick layers that act as pinning sites [4].

    固気液三相接触線のダイナミクスは界面現象が複合した未踏領域であり、例えば、蒸気泡や凝縮液滴の動きを仮定無しに予測することは未だ実現できていない。本研究では濡れ現象・ピニング・すべり流動など伝熱と物質輸送を左右する接触線近傍の物理機構を真のナノスケール実験で解明する。具体的には、グラフェンに代表される二次元材料が具備する理想表面という特徴を活用し、異なる長所を持つ複数の顕微観察方法および微細加工技術を駆使することで、原子オーダーの欠陥や異分子吸着層などの固体表面因子が与える影響を明らかにしつつナノからマクロまでのシームレスな接触線の学理構築を目指す。

    固液界面は熱や流体を扱う科学の根幹的要素の一つであるが、ナノ・分子スケールでの理解は不足している。特に、固体面から100 nm程度の領域にはいくつもの界面特有の局所的状態が分布・共存している一方で、その多様さと計測の困難さゆえに殆ど未解明のままである。本研究では周波数変調型原子間力顕微鏡を基盤として、水和構造や電気二重層など複雑に相互干渉する固液界面のナノ性状を同時に計測できる新しい実験手法を開発する。この新手法によって、水-固体界面におけるナノ性状群の相互関係と連成問題を実験的に探究することで、その分子的描像の明確化を目指す。

    固体‐液体‐気体が重なる三相界線は種々の工学・化学プロセスにおいて重要な役割を果たす一方、その物理には今でも不明な点が多い。特に理論的仮定とはかけ離れた、実際の固体面上のようにナノスケールの凹凸を持つ表面での物理はその重要性にも関わらず完全な理解には程遠い。本国際共同研究では、申請者のナノ界面計測技術と国際共同研究者の表面微細加工技術を融合することで、実表面上での三相界線の物理の解明を目指す。

    固気液三相界線はその工学的重要性にもかかわらず、異なる三相が相互作用しあうためにその物理の調査が困難であり、新たな実験的手法による分子スケールでの現象理解が求められている。本研究では走査プローブ顕微鏡の中でも、従来の手法に比べて10倍以上高感度な周波数変調モードや表面電位を計測できるケルビンプローブフォース顕微鏡をさらに発展させ使い分けることによって、空気分子および不純物の吸着や凝縮層、固体表面の不均一性、および三相界線近傍の帯電状態が与える影響について調査する。

    The phase transition from liquid to vapor allows for highly efficient cooling; however, the initial stages of this process cannot be observed using optical microscopes due to insufficient resolution, leaving many mysteries unanswered. This research aimed to gain new insights by observing solid-liquid interface during heating at the nanoscale using atomic force microscopy. As a result, we revealed that surface roughness of approximately 0.2 nm, which is negligible at the macroscale, acts as a powerful pinning site for the nanoscale fluid. We also conducted research in parallel using transmission electron microscopy and molecular dynamics simulations, obtaining valuable insights into nanoscale droplets and bubbles.
