1.The oxidation resistance temperature 【OF】 UFD/SiO2 composites was at least 140℃ higher than that of the pristine UFDs, while it changed relatively little as the shell thickness increased from 10 nm to 50 nm and reached a maximum around 597℃.
2.UFD/SiO2 composites with shell thickness of about 10 nm exhibited 【A】 better suspension stability among the pristine UFDs and other UFD/SiO2 composites with thicker shell thicknesses, which can stably suspend in 0.5 mol/L multi-component inorganic salt solution for 24 h. （这句话后半句的which所指有些模糊，可以另起一句，简单的用 It can stably...描述）
3.Because all organic groups would be eliminated at this temperature [19], which facilitates the observation of the changes in UFD/SiO2 composites during heating process.（这句话本应因果关系从句，后半句用which引导不合适。可以改为下面的说法。另外，后半句的内容我不能完全理解，我试图按照我的理解给予修改，不知是否合适：
Because all organic groups would be eliminated at this temperature [19], 【the observed changes in UFD/SiO2 composites during heating process was facilitated.】
4.Almost no silica shell formed on the surfaces of the UFDs with the 【addition of 0.5 ml ammonia】. 我觉得这句话改成下面的样子更好些：
4.Almost no silica shell formed on the surfaces of the UFDs 【was observed】 with the 【addition of 0.5 ml ammonia】 |
