摘要

采用远区共振能量转移（FZRET）技术在醋酸钾微射流中探测溶液中的超分子结构。这种先进的x射线光谱技术依赖于供体原子（即核心电离的钾离子）与几纳米外的受体原子之间的共振能量转移。这些实验揭示了离子在水中的不均匀分布，并与4.1 M浓度下纳米级离子团的存在相一致。

Probing Supramolecular Structures in Solution by Resonant Energy Transfer in the X-ray range

Supramolecular structures in solution are probed using Far-Zone Resonant Energy Transfer (FZRET) in an aqueous potassium acetate microjet. This advanced X-ray spectroscopic technique relies on the resonant energy transfer between donor atoms, i.e. core-ionised potassium ions, and acceptor atoms a few nm away. These experiments reveal an inhomogeneous distribution of ions in water, and are consistent with the presence of nm-sized ionic clusters at 4.1 M concentration.

期刊介绍： Chemical Science is a journal that encompasses various disciplines within the chemical sciences. Its scope includes publishing ground-breaking research with significant implications for its respective field, as well as appealing to a wider audience in related areas. To be considered for publication, articles must showcase innovative and original advances in their field of study and be presented in a manner that is understandable to scientists from diverse backgrounds. However, the journal generally does not publish highly specialized research.
