| 1 | An anthrax bacteria or spore might have a minimum size of one micron. | |
| 2 | The template preparation technique is the best method of fabricating hollow particles with controllable diameter. | |
| 3 | The particles synthesized by this method have good crystalline character, narrow size distribution. | |
| 4 | We can get calcium carbonates of different shapes and grain sizes through different techniques. | |
| 5 | Because of vast volume of a dam,the coarse aggregate of concrete used for constructing a dam is of large grain size and more grading. |
