The role and importance of nanoparticles for interstellar chemistry and beyond is explored within the framework of (THEMIS), focusing on their active surface chemistry, the effects of nitrogen doping and the natural selection of interesting nanoparticle sub-structures. Nanoparticle-driven chemistry, and in particular the role of intrinsic epoxide-type structures, could provide a viable route to the observed gas phase OH in tenuous interstellar clouds en route to becoming molecular clouds. The aromatic-rich moieties present in asphaltenes probably provide a viable model for the structures present within aromatic-rich interstellar carbonaceous grains. The observed doping of such nanoparticle structures with nitrogen, if also prevalent in interstellar dust, could perhaps have important and observable consequences for surface chemistry and the formation of precursor pre-biotic species.
在（THEMIS）框架内探讨了纳米颗粒在星际化学及其他领域中的作用和重要性，重点关注其活性表面化学、氮掺杂的影响以及有趣纳米颗粒子结构的自然选择。纳米颗粒驱动的化学过程，特别是本征环氧化物型结构的作用，可能为在稀薄星际云中观测到的气相OH提供一条可行途径，这些星际云正朝着成为分子云的方向发展。沥青质中存在的富含芳烃部分可能为富含芳烃的星际碳质颗粒内的结构提供了一个可行模型。如果这种纳米颗粒结构的氮掺杂在星际尘埃中也很普遍，那么可能会对表面化学和前体益生元物种的形成产生重要且可观测的影响。
