摘要

? 2023 The Author(s)After consultations with colleagues, the authors decided to clarify the following: Introduction The expression “These nanofluids still contained toxic nanoparticles. In addition, several articles reported brewed coffee 15 and Azadirachta Indica 16 used as the eco-friendly absorbers of solar radiation” should read as “These nanofluids still contained toxic nanoparticles. In addition, starting from the pioneering work by Alberghini et al. 21 which first used brewed coffee in direct absorption solar collectors, several articles reported brewed coffee 15 and Azadirachta Indica 16 used as the eco-friendly absorbers of solar radiation”. Conclusion The expression “To our knowledge, this is the first documented nanofluid with low toxicity.” should read as “To our knowledge, this is the first documented work on nanofluids (mean particle size < 100 nm) which also achieves low toxicity against Daphnia magna.” References 21 M.
