Abstract
We report here the first direct observation of U(V) in uranium binary oxides and analyze the gradual conversion of the U oxidation state in the mixed uranium systems. Our finding clarifies previous contradicting results and provides important input for the geological disposal of spent fuel, recycling applications, and chemistry of uranium species.
摘要
我们在这里报告了在铀二元氧化物中直接观察到 U(V)的首例，并分析了混合铀体系中 U 氧化态的逐渐转变。我们的发现澄清了先前相互矛盾的结果，并为乏燃料的地质处置、回收应用和铀物种化学提供了重要的信息。
