Abstract：
New materials and processes1 can improve the performance of existing devices or enable new  ones1-5 that  are  also  environmentally  benign.  In  this  context,  graphene  and  other 2D crystals are emerging as promising materials,1-5 with the opportunity to enable new products.1 A  key  requirement  for  applications  such  as  flexible  electronics  and  energy  storage  and conversion  is  the  development  of  industrial-scale,  reliable,  inexpensive  production processes,2 while providing a balance between ease of fabrication and final material quality  with on-demand properties. Solution-processing2,6 offers a simple and cost-effective pathway to fabricate various 2d crystal-based  (opto)electronic  and  energy  devices,  presenting  huge  integration  flexibility compared to conventional methods. Here, I will present an overview of graphene and other 2d  for  flexible  and  printed  (opto)electronic  and  energy  applications,  starting  from  solution processing  of  the  raw  bulk  materials,2 the  fabrication  of  large  area  electrodes3 and  their  integration in the final devices.7,8,9,10,11,12

CV of Dr. Francesco Bonaccorso
  Francesco gained his Ph.D. from the University of Messina in Italy. In June 2009 he was awarded a Royal Society Newton International Fellowship at the Engineering Department of Cambridge University, and elected to a Research Fellowship at Hughes Hall, Cambridge. In 2012, He received the Cambridge MA degree. He organized the 10 years science and technology roadmap for the graphene flagship programme, by arranging the contributions of numerous universities, research institutes and companies worldwide. His research interests encompass solution processing of carbon nanomaterials (such as graphene, nanotubes and nanodiamonds), inorganic layered materials (e.g. MoS2, WS2, Bi2Te3, etc.), and their combination in hybrid superstructures, their spectroscopic characterization, incorporation into polymer composites and application in conversion and storage devices, smart windows, touch‐screens, and ultrafast lasers.
