关于纳米技术在城市中的应用，包括在建筑环境的设计和建设中的应用的愿景表明，这些技术对于解决城市可持续性问题至关重要。我们认为，这种愿景往往忽视了两个关键且相互关联的因素。首先，对未来纳米增强城市的猜测往往依赖于有缺陷的城市可持续性概念，这些概念低估了根深蒂固的市场经济、风险评估和颠覆性技术吸收范式所带来的挑战。其次，城市官员、非政府组织和公民等利益相关者很少有机会尽早考虑纳米城市技术的潜在利益和不利影响的性质和分布。早期参与的局限性将导致在使用纳米技术促进城市可持续发展方面出现问题和错失机会。在这篇文章中，我们批判性地探讨了纳米增强城市的概念及其与城市可持续性相关的承诺和局限性。在此基础上，我们概述了参与研究的议程，以支持城市纳米技术的预期治理。

To minimize market fragmentation, optimize efficiencies through compatible digital architectures, and encourage collaboration, high-level smart city harmonization efforts have been advocated across Europe. This paper critically analyzes attempts by the European Innovation Partnership for Smart Cities and Communities Six Nations Forum (EIP-SCC 6N) to constitute a common smart city management framework through application of a generic Blueprint. Analysis highlights how these efforts are brought to bear through four techniques: simplification, interoperability, integration, and authorization. Examining the adoption (and rejection) of these techniques underscores the importance of attending to distinctive urban contexts and alternative ways of knowing and acting in the city.
