Strongly thermophilic nanofluids are able to transfer either small or large quantities of heat when subjected to a stable temperature difference. We investigate the bistability diagram of the heat transferred by this class of nanofluids. We show that bistability can be exploited to obtain a controlled switching between a conductive and a convective regime of heat transfer, so as to achieve a controlled modulation of the heat flux.

As the need for business to address pressing social and ecological issues intensifies, so does the importance of enhancing the development of sustainable marketing.The current dominant approach to sustainable marketing is based on a Triple Bottom Line (TBL) profitcentric worldview, which suggests that firms can simultaneously improve their financial well-being as they reduce negative social and ecological externalities.However, whereas the scope of TBL marketing is limited to sustainability initiatives that enhance profits, there is a growing need for-and interest indeveloping a sustain-centric approach to marketing that relaxes the need to maximize financial well-being in order to optimize social and ecological well-being.
