Converting unconventional precursors into advanced separation materials can reduce manufacturing complexity while affording economic and environmental benefits. Here we report the conversion of various aluminum-containing commercial products, such as recycled beverage cans and aluminum foil, to both supported and nonsupported metal−organic frameworks (MOFs). Supported MOF/aluminum composites grow from and on aluminum via hydrothermal treatment to create multiple supported MOF topologies. The same precursor is also employed to generate nonsupported MOFs using HCl (aq) as an etching agent. High yields (∼83%) of MIL-53(Al) are achieved using aluminum foil, with products possessing textural properties that are consistent with conventionally synthesized materials. This study provides a synthesis methodology for enhancing the economic viability of next-generation separation materials.
Hubert Dreyfus has argued that cases of absorbed bodily coping show that there is no room for self-awareness in flow experiences of experts. In this paper, I argue against Dreyfus' maxim of vanishing self-awareness by suggesting that awareness of agency is present in expert bodily action. First, I discuss the phenomenon of absorbed bodily coping by discussing flow experiences involved in expert bodily action: merging into the flow; immersion in the flow; emergence out of flow. I argue against the claim that flow experience does not involve an awareness of agency for each of these features, while conceding that fluent agency does not involve self-awareness in the thetic sense. I challenge the assumption that the awareness of fluent agency must be understood in terms of a thetic awareness of agency. Instead, I develop an Anscombean account of the awareness of fluent agency in terms of the phenomenal character of knowing one's aims. I respond to the challenge that if an Anscombean account of the awareness of agency is to succeed, then agents must be able to answer Anscombean questions. I consider the objection that awareness of agency is not a form of self-awareness by outlining an account of self-awareness as self-synthesis that is distinct from self-perception and selfascription, but which makes room for self-awareness in expert bodily action.
Nature aesthetics is concerned with four core questions: What is a natural environment? What is relevant, psychologically speaking, to the aesthetic appreciation of natural environments? How ought we to aesthetically appreciate natural environments? What is the relationship between nature aesthetics and environmental ethics? In this essay, I first address in Section 2 whether theorizing about nature aesthetics is possible by challenging the non‐aesthetics view, according to which aesthetic appreciation of nature is not possible, and the relativity view, according to which aesthetic appreciation of nature is possible, but it is an anything goes affair. In Section 3, I outline the core arguments for scientific cognitivism and provide objections to those arguments, making room for alternative views. In Section 4, I outline the distinction between cognitivism and non‐cognitivism and discuss the benefits of the engagement view. In Section 5, I outline the sympathetic imagination view of nature aesthetics. In Section 6, I discuss the emotions view. In Section 7, after summarizing the lessons learned from these debates, I argue for a new view— Enacting Nature's Value— which proposes that we need to rethink nature aesthetics in terms of an enactivist account of aesthetic agency according to which the aesthetic appreciation of nature is a skilled action. In Section 8, I close by considering four future directions for nature aesthetics in the second generation of inquiry.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
