DESCRIPTION:Self-assembled structures such as micelles and vesicles have f
 requently been discussed as model systems for biological cells because the
 y can mimic their ability to compartmentalize matter for biological and ma
 terial processing such as DNA-replication and nanoparticle synthesis respe
 ctively. However\, in contrast to most synthetic self-assembling systems t
 he natural systems are not equilibrium processes. Attention is therefore n
 ow focusing on dissipative self-assembling systems where energy input is r
 equired to sustain the self-assembled state. These systems have the potent
 ial to adapt themselves and enter into different self-assembled states dep
 ending on environmental conditions whereas their equilibrium counterparts 
 can only assemble or disassemble.\nRecently\, we have constructed a dissip
 ative self-assembling system using a chemical fuel[DOI: 10.1002/anie.20100
 1511] and presently more examples are being worked on. The thermo- dynamic
  description of such non-equilibrium processes[DOI: 10.1007/s10765-013-146
 4-5] invokes some interesting questions regarding the nature of the entrop
 y production\, the relation between the driving forces and the dissipation
  rate\, and the energy transduction pathways that will be discussed during
  this presentation.\n
