  研究成果名稱(英)：Investigating states of gas in water
  簡要記述(中)：在傳統的認知中，氣體在水中只有兩種狀態:均勻分散的單一氣體分子及氣泡。本所黄英碩研究員及徐偉豪博士用穿透式電子顯微術研究包在石墨烯層中的氣體過飽和水，發現兩種主要新的結構:(1)多晶奈米顆粒(直徑數奈米)在液態水中 ，(2)籠形水合物結構 (整體大小約100奈米左右或更大)。在籠形水合物結構中，水分子形成多晶的籠形結構，內有很多包氣體分子的小籠，小籠間距4-8奈米。這些結構，特別是籠形水合物結構，可能解開很多關於氣體溶在水中的長久之謎，例如氣體溶於水中異常的熱力學性質、冰山模型、奈米氣泡、及氣泡形成前的微核等。此研究成果發表於Chem. Sci. 12, 2635 (2021)，Nature Chemistry的news & views也報導此成果 [Nature Chemistry 13, 212 (2021)]。
  簡要記述(英)：In the conventional paradigm of gases dissolved in water, only two states are assumed to exist: well-dispersed gas monomers and gas bubbles. Ing-Shouh Hwang and Wei-Hao Hsu employed transmission electron microscopy (TEM) to uncover two types of new structures in gas-supersaturated water encapsulated in graphene liquid cells: (1) individual polycrystalline nanoparticles (typically several nanometers in diameter) in liquid water, and (2) clathrate structures (often ~100 nm or larger in lateral size). In the clathrate structures, water molecules form a polycrystalline matrix hosting a high density of gas-containing cells (cell separation of 4-8 nm). These structures, particularly the clathrate structures, may resolve many long-standing puzzles about the dissolution of gases in water, such as abnormal thermodynamic properties, the iceberg model, bulk nanobubbles, and micronuclei that nucleate gas bubbles. The results were published on Chem. Sci. 12, 2635 (2021). It was also reported in news & views of Nature Chemistry [Nature Chemistry 13, 212 (2021)].

  研究成果名稱(中)：水中空氣分子在脂質雙層的新角色
  研究成果名稱(英)：Emerging roles of air gases in lipid bilayers
  簡要記述(中)：本院物理所黃英碩、陳彥龍及應科中心李超煌帶領其同仁發現,溶在水中的空氣分子會聚集在脂質雙層膜內，影響脂質雙層膜的力學性質及穩定性。研究團隊利用差動共焦以及螢光顯微術量測脂囊泡膜,加上原子力顯微術量測支撐性脂雙層膜，相較在一般實驗條件下所製備的脂質雙層膜，去除氣體的水溶液中所形成的脂質雙層膜較軟且不穩定；而高濃度氮氣的水溶液中可觀察到脂質雙層膜的彎曲剛性與穩定性皆有提升，三元脂質膜的相分離現象則更為遲緩。分子動力模擬印證溶解在水中的氧和氮，會聚集在脂質雙層膜內，尤其氮分子停留在脂質雙層膜中的時間更長，對脂質尾端有更高的親和力是提高脂膜剛性的主因，可以定性解釋實驗所觀察到脂質雙層膜的彎曲剛性如何隨著氣體分子的濃度變化而改變。這些發現對於脂質雙層膜及細胞膜具有基礎而廣泛的影響，也意涵溶於水中的空氣分子可能對水溶液中很多其他物理化學及生物系統的性質及自組裝行為有某種程度的影響。
  簡要記述(英)：Ing-Shouh Hwang, Yeng-Long Chen of Institute of Physics, and Chau-Hwang Lee of Research Center for Applied Sciences, together with their co-workers, report enrichment of dissolved air gases in lipid bilayers, which affects the mechanical properties and stability of lipid bilayers in aqueous solutions. Experimental measurements were based on differential confocal microscopy and fluorescence microscopy on giant unilamellar lipid vesicles, and atomic force microscopy on supported lipid bilayers. In comparison to lipid bilayers in ambient solutions (without gas control), the bilayers in degassed solutions are softer and less stable. High concentrations of nitrogen increase the bending moduli and stability of the lipid bilayers and impede phase separation in ternary lipid bilayers. Molecular dynamic simulations verified the enrichment of nitrogen and oxygen inside the lipid bilayer in supersaturated solutions. The simulations found that nitrogen accumulate in the lipid bilayer, and higher nitrogen affinity to the lipid tails accounts for increased bending rigidity. This confirms experimental observations of increased lipid bilayer bending moduli with increasing gas concentration. These findings have fundamental and wide implications for phenomena related to lipid bilayers and cell membranes. The results also imply that dissolved air gases may affect the properties and self-assembly behaviors in other physical, chemical, and biological systems in solutions.

  研究成果名稱(中)：發散電子束繞射技術：觀測二維材料奈米級撓曲的新技術
  研究成果名稱(英)：Visualizing Graphene Ripples at the Nanometer Scale with Electron Diffraction
  簡要記述(中)：物理研究所黃英碩研究員帶領的實驗團隊與瑞士的理論學者合作，發展了「發散電子束繞射技術」，能觀測二維材料奈米級撓曲。研究顯示，實驗取得的高角度繞射訊號中夾帶著石墨烯碳原子的三維位移資訊。我們發現使用低能量發散電子束(50-250 eV)局部照射石墨烯時，可觀測石墨烯的奈米級撓曲，位移的靈敏度可小至1 Å 。由繞射圖形的細節可區分橫向及縱向撓曲，甚至可判定縱向相較於電子源方向為凸起或凹下。除了石墨烯，此項新技術將可運用於研究二維材料中奈米級撓曲的動態行為。此技術亦顯示，二維材料的三維形貌及應變將可能藉由演算法重建繞射圖形得以實現。
  簡要記述(英)：We have demonstrated that divergent beam electron diffraction (DBED) allows imaging graphene rippling at the nanometer scale. This work is a collaboration between the Taiwan team and Dr. Tatiana Latychevskaia of Switzerland. The experiments were carried out in Taiwan led by Ing-Shouh Hwang; theoretical simulations were done in Switzerland. The results indicate that the high-angle diffraction spots carries information about the three-dimensional (3D) displacement of graphene atoms. Displacements as small as 1 angstrom can be detected when imaged with low-energy electrons (50 – 250 eV). The out-of-plane and in-plane ripples are distinguishable by their appearance in the DBED patterns. This work indicates the possibility that the 3D topography and strain distribution of two-dimensional (2D) materials can be retrieved from the DBED patterns. It also offers a new technique to study rippling dynamics of 2D materials at a high spatial resolution and a high speed.

  研究成果名稱(中)：疏水固體與水介面之研究及微小封閉空間內的氣體排序
  研究成果名稱(英)：Study of hydrophobic/water interfaces and ordering of gases confined in a small space
  簡要記述(中)：疏水固體與水的介面是一爭議很大的介面，已有報導水中氣體會累積到此介面，形成二維及三維結構。但很多問題至今仍是個謎，例如：為何氣體會到此介面、此氣體結構為何、又為何這些結構能穩定存在。中研院物理所黃英碩領導的團隊以先進的原子力顯微術首度在石墨與水介面解析出氧及氮形成的數種結構，其中有二維有序結構(固態氣體)，二維無序結構，及三維似液態等結構，此發現似乎違背一般對相圖的認知，即常溫常壓下之氣體應為氣態，但過去有不少研究顯示，在室溫下鈍氣常以固態或液態方式存在固體內奈米級的空間。這些研究與我們的觀察顯示氣體在微小封閉空間內不能以一般巨觀氣體的相圖解釋，因此首度提出”介面誘發排序”來解釋這不尋常的結構，此觀念也為高密度氣體儲存技術提供一新方向。此論文發表於Nature系列的Scientific Reports 。http://www.nature.com/srep/2014/141126/srep07189/full/srep07189.html?WT.ec_id=SREP-639-20141202.
  
  此團隊也提出水中氣體分子傾向吸附到疏水固體表面，因為此表面提供了位能較低的吸附位置，因此疏水表面能有效捕捉溶解在水中的氣體分子，可用來理解水中生物如何有效獲取微量的氧分子及很多水中的現象。而在介面聚集的氣體分子團，由於分子間只有微弱的凡得瓦力，可視為低黏滯的液體以解釋疏水固體表面常見的邊界滑移現象，此流體力學的百年之謎可能就是此特殊介面氣體結構所造成。
  簡要記述(英)：The interfaces between water and hydrophobic solids are under highly debate among researchers. There have been numerous reports that gases dissolved in water can accumulate at this type of interfaces. However, many questions, such as why gases segregate to the interfaces, the nature of the interfacial gas structures, and the high stability of the gas structures, remain unanswered. With advanced AFM techniques, the research group led by Dr. Ing-Shouh Hwang resolved various structures of oxygen and nitrogen at an interface between water and a hydrophobic solid (graphite). These gas structures can be in two-dimensional ordered (solid gas), two-dimensional disordered, or three-dimensional liquid-like states under ambient conditions, which contradicts the conventional concept based on the phase diagrams of bulk gases. This observation is consistent with previous observations of solid or liquid nanoprecipitates of inert gases in solids at room temperature. These results clearly show that the ordering of gases confined in a small space cannot be understood with the phase diagrams of bulk gases. A new concept, interface-induced ordering, is proposed to explain this special thermodynamic phenomenon. This concept provides a new direction in developing techniques for high-density gas storage. The results were published in a Nature-series journal, Scientific Reports. http://www.nature.com/srep/2014/141126/srep07189/full/srep07189.html?WT.ec_id=SREP-639-20141202.
  
  The group also proposes that gas molecules dissolved in water tend to adsorb at hydrophobic solid surfaces, because this type of surfaces provide low-chemical-potential sites. Thus hydrophobic surfaces can effectively catch gases dissolved in water, which may also have implications regarding the breathing of aquatic lives and many phenomena in water. Since there are only weak van der Waals interaction among gas molecules, the liquid-like interfacial gas structures can act as a low-viscosity liquid to explain the boundary slip for water flow over hydrophobic solid surfaces. This long-standing puzzle in fluid dynamic may simply result from the special properties of the interfacial gas structures.
