Figure 5. (A) Photographs, (B) SEM micrographs, and (C) contact angle images of the liquid marbles comprised of Fe₃O₄, Ni NPs, and CNTs, respectively, aligned vertically. Pictorial evidence and image analysis of evaporating liquid marbles with (D) Fe₃O₄, (E) Ni, and (F) CNT are also depicted. Tracking the surface temperature evolution is achieved via an infrared (IR) camera for (G) Fe₃O₄-LM, (H) Ni-LM, and (I) CNT-LM. (J) Demonstrates the evaporation rates. (K) Depicts morphology images of LM created through both the imprinting and rolling methods, as well as typical snapshots of a Ni NP-evaporating liquid marble. (L) elucidates the evaporation processes of LMs enveloped by either Fe₃O₄ NPs or CNTs. Reprinted with permission from ref.^[95]. Copyright 2023 Elsevier.
