The emerging field of molecular electronics could take our definition of portable to the next level, enabling the construction of tiny circuits from molecular components. In these highly efficient devices, individual molecules would take on the roles currently played by comparatively-bulky wires, resistors and transistors.<br><br><a href="http://phys.org/news/2014-09-future-molecular-electronics.html">READ MORE ON PHYS.ORG</a>
