It was observed that the optimum temperature for the fluorous biphasic regioselective nitrations of toluene, ethylbenzene, flurobenzene, chlorobenzene, bromobenzene, odobenzene and diphenyl ether were 80℃, 60℃, 60℃, 60℃, 80℃, 80℃ and 70℃ respectively. The catalyst had almost no activity when the reaction system contained 25% of water. Simultaneously, increasing the volume ratio of fluorous phase and organic phase in the system in which the fluorous phase can miscible with organic phase could decrease ortho-para ratio.

发现甲苯、乙苯、氟苯、氯苯、溴苯、碘苯加二苯醚的最佳氟两相选择性硝化温度分别为80℃、60℃、60℃、60℃、80℃、80℃和70℃，当加入25%的水时，催化剂已基本失去活性，在氟相和有机相能完全互溶的体系中升高氟相和有机相的体积比有利于降低邻对位比值。

Meanwhile, the activation of caspase-3 could be found increased in ClearCa-6 with lower expression of XIAP, but not in ClearCa-2 with higher expression of XIAP when exposed to various apoptotic inductions.

4意外发现Nitrite存在下UVA的照射可引起Caspase-3活性的抑制，并证明此抑制作用的直接机制是UVA使Nitrite在光解作用中释放NO，使Caspase-3受到亚硝化修饰而丧失活性。

This study investigated the biodegradation of benzene in laboratory anaerobic microcosms.

但是，苯—溶解度大且为致癌物，在厌氧条件下，特别是反硝化条件下的生物降解仍是一个有争议的问题，限制了生物恢复技术的应用。
