这份报告由英国皇家环境污染委员会完成，它说，尽管纳米材料迄今为止没有表明有害的迹象，但是对其潜在风险的研究还有“严重的欠缺”。

The UK-based Royal Commission on Environmental Pollution says that while the materials have so far shown no sign of being harmful, there is a "major gap" in research about their potential risks.

我意识到，在理解如何构造无机材料，以及控制它们与环境之间的相互影响方面，纳米技术将拥有巨大的用武之地。

I realised how much nanotechnology had to offer in understanding how to build up inorganic materials and control how they interact with the environment.

而大尺寸石墨烯在性能方面之所以起到关键性的作用，是因为大尺寸石墨烯通过改善阳极材料的完整性，为纳米阳极材料提供了一个高循环稳定性的环境。

The large size of the graphene plays a key role in the performance because a larger size provides a higher cycling stability of the nanosized anode materials by improving their mechanical integrity.
