请帮我看一下,语法和句型有无问题,有问题该如何改?谢谢了
Metal-coated cenosphere particles, a novel kind of lightweight ceramic composite material, have recently attracted a great deal of research attention [1-5]. These metal-coated particles often present properties that are different from those of substrate particles (for example different surface chemical composition and different electric, magnetic and optical properties), thus making them attractive from both a scientific and technological viewpoint.

for example different surface chemical compositions <-加个s
or
for example a different surface chemical composition 加个a

看哪个是你想说的

最后
both scientific and a technological viewpoints <-加个s去个a

一样的问题啊，要细心啊

edit
其实最后一句应该吧both去掉
