We make glassy water in the form of nanofibers by electrospraying liquid water into a hyperquenching chamber. It is measured with means of differential scanning calorimetry, wide angle X-ray diffraction and Raman spectroscopy. It is found that two apparent glass transitions at = 136 K and = 228 K are detected and non-crystallized water is observed at temperatures up to 228 K. This finding may expand the research objects for liquid water at low temperatures.
我们通过将液态水电喷雾到超淬火室中制成纳米纤维形式的玻璃态水。通过差示扫描量热法、广角X射线衍射和拉曼光谱对其进行测量。结果发现，检测到在136K和228K处有两个明显的玻璃化转变，并且在高达228K的温度下观察到未结晶的水。这一发现可能会扩展低温下液态水的研究对象。
