The present invention relates to compositions of submicron- to micron-size particles of antimicrobial agents. The first speed is faster than a second speed for storing meta-information based on information stored in a memory. An axial through-hole in the center permits the snug insertion of a rigid length of tubing to give the pillow axial rigidity. The extended area can be a support bar of a leadframe that is used as bond area for ground connections in a single-layer non-leaded leadframe.
