20.500.12556/RUL-165044 Integrating rooftop agriculture and atmospheric water harvesting for water-food production based on hygroscopic manganese complex The integration of atmospheric water harvesting and rooftop agriculture presents a promising solution for decentralized water and food supply in urban areas. However, the degradation of adsorption material kinetics after scaling up, coupled with fluctuations in solar energy, results in reduced and unstable water production. Herein, a composite adsorbent composed of manganese (II)-ethanolamine complexes incorporated into a hierarchical and interconnect polypyrrole-doped matrix is developed. This structure significantly reduces vapor diffusion resistance—a crucial factor impeding rapid scale-up kinetics, enabling water uptake of 2.54 g g−1 at 90% RH, with 62% of water released within 30 min, facilitating daily multiple capture-release cycles. Incorporating a hybrid desorption mode that combines PV electrical and solar heating further achieves stable and high-yield water production. Ultimately, through simulation and feasibility verification, the atmospheric water-irrigated rooftop farm realizes water and food production yield of 879.9 gwater m−2sorbent day−1 and 1.28 kgfood m−2device within 14 days without human intervention and independent of external water inputs. These findings highlight the potential of integrating AWH technology with rooftop farming as a pathway to sustainable urban development through decentralized water and food co-production. atmospheric water harvesting solar energy renewable energy sources composite sorbents advanced thermal engineering energy-water-food nexus water self-sufficient agriculture atmosfersko pridobivanje vode sončna energija obnovljivi viri energije kompozitna sorpcijska sredstva napredni toplotni inženiring povezava energija-voda-hrana vodno samozadostno kmetijstvo true false true Angleški jezik Slovenski jezik Članek v reviji 2024-11-21 11:17:17 2024-11-21 11:17:23 2026-05-20 04:45:49 0000-00-00 00:00:00 2024 0 0 11 str. iss. 38, art. 2402839 Vol. 34 2024 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 536:502.21:523.9 1616-301X 10.1002/adfm.202402839 215926275 RAZ_Shan_He_2024.pdf RAZ_Shan_He_2024.pdf 1 89258FBD3D6D5AB4AC01A1F407DF4EA8 f67e861ae5ac10096e0f3357dee842cb915533914023aa6af4ab58a0fc22ed10 89e35cbc-5369-11f1-b0ab-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=234038 https://onlinelibrary.wiley.com/doi/10.1002/adfm.202402839 1 68021d5b-a7f1-11ef-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=195984 Fakulteta za strojništvo 0 0 0
