1.	Scientists from which country developed a "rewritable" paper?
Answer» Scientists from the Fujian Normal University in China developed a "rewritable" paper that can be drawn or printed on over and over again by changing the temperature. The new material consisted of three layers in a sandwich-like structure where the text could be changed or wiped clean over 100 times by changing the temperature. According to a study published in the journal ACS Applied Material & Interfaces, the messages can last more than half a year, compared to other re-writable papers. It can be used in practical applications such as long-lasting information recording and reading, rewritable label, reprintable display.
