DESCRIPTION:2. Plasmonics for Sustainability:  harvesting light energy for
  new solar applications\nThe intense research activity of the past two dec
 ades focused on the collective electronic oscillations in high-electron-de
 nsity media\, known as surface plasmons\, has led to multiple breakthrough
 s in fields ranging from chemical sensing and catalysis\, to active optica
 l devices\, solar light harvesting\, even nanomedicine.  For many of these
  applications\, the original focus on noble metals may ultimately limit th
 eir transition from the research laboratory to widely used commercial tech
 nologies.  We will describe several research directions that\, as they poi
 nt towards more sustainable materials\, open up new research opportunities
 . Aluminum\, the most abundant metal on earth\, opens the door to new colo
 rimetric sensing applications and opportunities for active devices[1-4].  
 Graphene in its smallest form\, that of polycyclic aromatic hydrocarbon mo
 lecules\, can support intense\, optical frequency plasmon oscillations wit
 h the addition or removal of a single electron from the neutral molecule. 
  In applications that directly address sustainability\, we will discuss ho
 w plasmonic nanoparticles can be used to generate steam using nanoparticle
 s and sunlight without heating the fluid volume. This effect can be used f
 or a wide range of direct solar processes and applications\, such as the s
 olar distillation of liquids and of liquid mixtures [5-9]\, the green prod
 uction of bioethanol from cellulosic feedstock\, and a direct solar-driven
  approach to membrane distillation suitable for off-grid\, remote site app
 lications.\n\n\n1.	J. Olson et al.\,  PNAS 111\, 14348-14353 (2014).\n2.	N
