A composition that includes functionalized polyhedral oligomeric silsesquioxanes derivatives of the formulas TmR3 where m is equal to 8, 10 or 12 and QnMnR1,R2,R3 where n is equal to 8, 10 or 12 are provided. The barrier has an inside wall, an outside wall and a space between the inside and outside walls. A date is read from the RTC and a character code corresponding to the year, month, and day to be displayed on the screen of the monitor is read from the CG-ROM at the CRTC.
