Abstract: This paper describes a research based scenario project on sustainable consumption in Belgium. In the Consentsus project a scenario method was developed and tested by the research team to assess scenarios both as learning and participation tools for sustainable consumption. By using a decomposition analysis a solid ground was laid to adequately summarize three guiding principles on how to reach a (more) sustainable consumption: eco-efficiency, de-commodification and sufficiency. These ‘pure’ strategies – showing significant similarities with concrete discourses – were then translated into a participative process: two expert-driven workshops and interim research yielded three future images of food consumption as well as indications on their boundary conditions. These three images reflect significantly diverging approaches on how to organize practices related to food consumption. This structural diversity allowed us to address an archetypical consumer, i.e. a generalized consumer based on the specificities of the scenarios. These consumer perspectives do not aim at indicating real (even potential) groups, but aim at illustrating how the environment of interactions around the consumer fundamentally changes throughout the three sustainability discourses. It is argued that thinking through alternative modes of consumption is of importance to support and elucidate debate in governance arenas that address transitions towards a more sustainable consumption.

Composite sheets and nanotubes of different morphologies containing carbon, boron, and nitrogen were grown in the electric arc discharge between graphite cathodes and amorphous boron-filled graphite anodes in a nitrogen atmosphere. Concentration profiles derived from electron energy-loss line spectra show that boron and nitrogen are correlated in a one-to-one ratio; core energy-loss fine structures reveal small differences compared to pure hexagonal boron nitride. Boron and carbon are anticorrelated, suggesting the substitution of boron and nitrogen into the carbon network. Results indicate that singlephaase CyBxNx as well as separated domains (nanosize) of boron nitride in carbon networks may exist.
