Hitting a dust mote-sized particle would impart the same kinetic energy as slamming head on into a speeding freight train.

与尘埃级别的颗粒相撞，都可能得到与高速货车迎面相撞的能量。

The converters could apparently also be used for optical manipulation of atom-sized objects, inexpensive ultra-high resolution microscopic imaging, and possibly even table-top particle accelerators.

显然这些转换器也可以被用于对原子大小目标进行光学操作，进行价格低廉的超高分辨率显微成像，而且甚至可用于台式离子加速器。

FT-IR, TEM and other paper testing equipment respectively characterized the structure, the particle morphology of the resultant dispersions and the physical properties of the sized paper.

用FT - IR、TEM和纸张物理性能检测的手段对聚合物结构、乳胶粒子形态以及应用性能进行了表征。

As you're swiping your boarding pass ( or smartphone), the machine also scans it for particle-sized traces of explosive materials and sends the all-clear or no-go in less than two seconds.
