#Toward'green'paper-thin, flexible electronics (Nanowerk News) The rapid evolution of gadgets has brought us an impressive array of smart products from phones to tablets, and now watches and glasses. But they still havent broken free from their rigid form. Now scientists are reporting in the journal ACS Applied materials & Interfaces("Let It Shine: A Transparent and Photoluminescent Foldable Nanocellulose/Quantum dot Paper")a new step toward bendable electronics. They have developed the first light-emitting, transparent and flexible paper out of environmentally friendly materials via a simple, suction-filtration method. A new, environmentally-friendly paper that glows could lead to sustainable, roll up electronics. American Chemical Society) Technology experts have predicted long the coming age of flexible electronics, and researchers have been working on multiple fronts to reach that goal. But many of the advances rely on petroleum-based plastics and toxic materials. Yu-Zhong Wang, Fei Song and colleagues wanted to seek a greener way forward. The researchers developed a thin, clear nanocellulose paper made out of wood flour and infused it with biocompatible quantum dots tiny, semiconducting crystals made out of zinc and selenium. The paper glowed at room temperature and could be rolled and unrolled without cracking n
