This research is motivated by a recent Nature perspective article (Chu & Majumdar (2012) Nature 488, 294) on opportunities and challenges for sustainable energy. This proposal will aim at devising "nano/micro/meso/multifunctional intensification strategies for multiphase reactors/materials" with focus on upgrade/conversion of fossil/biomass energy. A common thread to these systems is their multiscale/multiphase nature and curse of scales that challenge both understanding and harnessing into well-conceived technologies. The emphasis will be on acquiring fundamental (experimental and theoretical) knowledge and understanding on three distinct but complementary spatial scales where phenomena may cause bottlenecks. These are scrutinized in three corresponding short-term objectives 1) Nanoscale intensification; 2)Microscale intensification in gas-liquid micropacked beds); 3) Meso/megascale intensification for RTIL-aided oil sand extraction.

这项研究是由最近一篇关于可持续能源的机遇和挑战的自然观点文章 (Chu & Majumdar (2012) Nature 488, 294) 推动的。该提案旨在设计“多相反应器/材料的纳米/微米/介观/多功能强化策略”，重点关注化石/生物质能源的升级/转换。这些系统的一个共同点是它们的多尺度/多相性质和尺度灾难，这对理解和利用精心设计的技术提出了挑战。重点是获取基础（实验和理论）知识和理解三个不同但互补的空间尺度，其中现象可能会造成瓶颈。这些在三个相应的短期目标中进行了仔细审查：1）纳米级强化； 2）气液微填充床中的微尺度强化）； 3）RTIL辅助油砂开采的细观/大规模强化。
