[求助] 求一句文献翻译，感谢！

The study of nanoscale materials in recent years has been extensive, particularly with respect to metallic NPs. Underpinning the significance of nanoparticulate materials in electroanalysis are the very specific properties which may be exhibited at the nanoscale but which are not typical of the corresponding bulk material. These include enhanced diffusion based on convergent rather than linear diffusion at the smaller NPs, high active surface area, improved selectivity, catalytic activity, higher signal-to-noise ratio and unique optical properties.

请问第二句中的“enhanced diffusion based on covergent rather than linear diffusion”是什么意思呢？

还有提到纳米粒子的性质有一条“enhanced mass transport”，这个有没有专门对应的翻译呢？

感谢！
