The white frame in (a) shows the EDX-mapping area which is pointed out separately in (c). The images (d–f) show the enrichment of the elements Al, Si, and Zr. An overlay representation of the lateral distribution of Al and Zr is shown in (g). i.e. from 2,290–2,330 eV....
Thomas C.-K. Yang2* & Ja-Hon Lin1* In this work, SiO2@α-Fe2O3 core-shell decorated RGO nanocomposites were prepared via a simple sol-gel method.The nanocomposites were prepared with different weight percentages (10, 30, and 50 wt %) of the SiO2@α-Fe2O3 core-shell on RG...
正长石是一种天然的硅酸盐矿,其组成可看作SiO2中部分Si原子被Al、K原子取代而成。当有25%的Si原子被Al原子取代(不足的价数由K原子补充)时,正长石的化学组成可表示为A.KAlSi3O6B.KAlSi3O8C.K2AlSi3O10D.KAl2Si6O14的答案是什么.用刷刷题APP,拍照搜索答疑.刷刷题(shuashua
