DESCRIPTION:One of the grand challenges facing humanity today is access to 
 sustainable materials and chemicals which are at the heart of sustainable 
 technologies. The production of materials\, chemicals and fuels from abund
 ant and renewable resources will eliminate our dependence on petroleum/cri
 tical metal based supplies and will provide access to a new economy based 
 on available reserves.\n\n\n	Carbon is the most versatile element known. It
  combines with other (carbon) atoms giving rise to new carbon materials wi
 th astonishing properties. The versatility and potential of carbon has att
 racted top recognition in the last decade for the work in fullerenes (1996
  Nobel Prize in Chemistry)\, CNTs (2008 Kavli Prize in Nanoscience) and gr
 apheme (2010 Nobel Prize in Physics). However\, the mystery and wonder of 
 carbon offers more to discover.\n\n\n	While carbon is widespread on Earth\,
  it has been mainly synthesised from fossil fuel based precursors with sop
 histicated and energy consuming methodologies that generate toxic gases an
 d chemicals. The preparation of carbon materials from renewable resources 
 is a key research challenge in terms of sustainability\, climate change an
 d economics. Since the beginning Nature created carbon from biomass.\n\n\n
 	We have demonstrated that it is possible to mimicking the natural process 
 of carbon formation and prepare carbon nanomaterials from biomass using mi
 ld hydrothermal processes. Along with amorphous carbon materials (denoted 
 HTC)\, this procedure also enables biomass transformation into useful chem
 icals such as 5-hydroxymethylfurfural (5-HMF) or levulinic acid (LA). Rece
 ntly\, we have discovered a third product of Hydrothermal Carbonisation - 
 a crystalline form of carbon - arising at the interface between the amorph
 ous HTC microspheres and the aqueous phase containing the biomass-derived 
 chemicals.\n\n\n	In this talk I will present some of the fundamentals gover
 ning the production of carbon nanomaterials and chemicals. We will also di
 scuss the application of HTC materials in electrocatalytic reactions such 
 as Oxygen Reduction Reaction and Oxygen Evolution Reaction.\n	Finally\, som
 e of the photo-physics governing the optoelectronic properties of the new 
 family of fluorescent hydrothermal carbon nanocrystals and their applicati
 ons as sensitizers in solar cells will be presented.\n\n \n
