Making Compatible Energy Planning with Urban Decision-Making: Socio-Energy Nodes and Local Configuration

International audienceThis chapter develops a specific concept, the socio-energy node (SEN), to helpunderstand energy assemblages in urban spaces. The SEN concept broadens the scope of planning tourban-energy interaction, the better to understand three main points. First, it informs questions abouthow to upgrade large energy networks and hybridize them with self-sufficient energy loops. Second, itreveals elements of energy socio-technical regimes that stimulate or hamper urban energy transition.Lastly, it aims to provide support for energy planners when modelling multi-actor energy systems. Wetherefore emphasize the importance of qualifying relationships between energy and urban-planningstakeholders and propose a method for implementing – and reconsidering – energy planning in cities,by breaking energy systems down into SENs and by studying how they “plug into" geographicconfigurations

Optical and electrochemical properties of metallophthalocyanine derivative Langmuir-Blodgett films

The formation of high-quality Langmuir-Blodgett films of copper and nickel phthalocyanine derivatives substituted with short branched chains is reported. Ellipsometric and polarized optical absorption measurements suggest that the phthalocyanine molecules have a preferred orientation, with their large faces perpendicular to the dipping direction and to the substrate plane. Electrochromic effects are also noted in these multilayer films
