Accurate knowledge of how this air flows over a surface will provide engineers with more detailed information about resistance,” he says.

正确认识空气流过表面的过程将提供工程师更多关于阻力的详细信息 ”他说。

It uses nanoscale materials to boost the performance of its batteries (making an electrode out of nanoparticles increases its surface area, which in turn decreases the battery's internal resistance and improves its ability to store and deliver energy).
