Introducing uncertain learning in an energy system model: a pilot study using GENIE
Energy system models based on experience curves are superior to conventional models in their treatment of the dynamics of technological development. However, assuming perfect foresight means that future learning rates are known with certainty, which is not realistic. An optimising model for the global electricity system, GENIE, has been extended to include imperfect foresight of learning rates. ...

Highly crystalline hydrothermal ZnO nanowires as photoanodes in DSCs
Vertically aligned ZnO nanowires (NWs) were prepared inside an autoclave by a hydrothermal procedure at temperatures above 100°C (HP). The effects of synthesis temperature and time on the morphology of ZnO NWs were carefully studied. The performance of HP ZnO NWs was compared with that of ZnO NWs grown by a conventional ambient pressure hydrothermal method at temperatures below 100°C (LP) ...
