Graphene is a nanomaterial with many promising and innovative applications, yet early studies indicate that graphene may pose risks to humans and the environment. According to ideas of responsible research and innovation, all relevant actors should strive to reduce risks related to technological innovations. Through semi-structured interviews, we investigated the idea of graphene as a risk held by two types of key actors: graphene researchers and innovation advisors at universities, where the latter are facilitating the movement of graphene from the (...) laboratory to the marketplace. The most common idea found is that graphene is not a risk due to, e.g., low toxicity, low amounts produced/used, and its similarity to harmless materials. However, some researchers and advisors also say that graphene is a risk, e.g., under certain conditions or due to a lack of risk-related information. We explain the co-existence of these seemingly contradictory ideas through the semantic ambiguity of the word risk and a risk/no-risk rhetoric, where risks are mentioned rhetorically only to be disregarded as manageable or negligible. We suggest that some of the ideas held by the researchers and innovation advisors constitute a challenge to responsible research and innovation regarding graphene. At the same time, we acknowledge the dilemma that the discourse of responsible innovation creates for the actors: denying graphene risks makes them irresponsible due to a lack of risk awareness, while affirming graphene risks makes them irresponsible due to their everyday engagement in graphene development. We therefore recommend more research into what researchers and innovation advisors should do in practice in order to qualify as responsible. (shrink)

Scientific writings and policy documents define the terms nanomaterial and nanoparticle in various ways. This variation is considered problematic because the absence of a shared definition is understood as potentially hindering nanomaterial knowledge production and regulation. Another view is that the existence of a shared definition may itself cause problems, as rigid definitions arguably exclude important aspects of the studied phenomena. The aim of this paper is to inform this state of disagreement by providing analytical concepts for a systematic understanding (...) of how, and even whether, nanomaterial and nanoparticle could and should be defined. To do this, we review definitions of nanomaterial and nanoparticle presented in research articles and policy documents. Definitions were identified by first conducting a Scopus search and then tracing cited definitions back to their sources. In total, 36 definitions were identified. Theories of definition from philosophy and linguistics provide analytical guidance for structuring and categorizing the identified definitions, and the main analytical dimensions of the definitions are then identified and discussed. Finally, we propose a framework for understanding the process of defining nanomaterial and nanoparticle. This framework considers both the generality needed for a shared understanding and the level of precision required for different purposes. (shrink)

Textual representation of graphene in Sweden’s most circulated newspapers is analyzed in 229 articles from 2004 to 2018. What is and is not said about graphene is explored through systematically identifying the lexical and grammatical patterns of sentences using the word “graphene.” Graphene is said to be a super material with certain properties, to be an object of research, commercialization, and application, and to have societal significance. Given frequent classifications of graphene as a nanomaterial in scientific discourse, there is notably (...) limited reference to graphene as “nano” in the newspapers and only marginal reference to risk. This paper discusses the findings regarding this Swedish newspaper discourse on graphene in relation to its intertextuality, i.e., how texts draw upon and recontextualize other texts: the Swedish newspaper discourse on graphene echoes discourses of promise formulated elsewhere in society; it is not very diversified in terms of themes; it is dominated by positive and neutral representations rather than by risk; and it makes limited reference to the nano-discourse, even though, according to most definitions, graphene is a nanomaterial.
