论文摘要
基于电子和X射线的高级原位技术越来越多地用于洞悉液体介质中的基本材料动力学。然而，电离辐射改变了溶液化学。在这项工作中，我们表明电离辐射将酸度与自左右解析。因此，pH不足以捕获辐射下水基系统的酸度。通过辐射分解模拟，我们提供了对酸碱相互作用的更结论性描述。最后，我们证明可以通过调节剂量速率并添加pH-嗜率物种来定制酸度。这为涉及电离辐射的研究打开了一个巨大的参数景观。
Advanced in situ techniques based on electrons and X-rays are increasingly used to gain insights into fundamental materials dynamics in liquid media. Yet, ionizing radiation changes the solution chemistry. In this work, we show that ionizing radiation decouples the acidity from autoprotolysis. Consequently, pH is insufficient to capture the acidity of water-based systems under irradiation. Via radiolysis simulations, we provide a more conclusive description of the acid-base interplay. Finally, we demonstrate that acidity can be tailored by adjusting the dose rate and adding pH-irrelevant species. This opens up a huge parameter landscape for studies involving ionizing radiation.
