Figure 2. (A) Preparation of micro-/nano-LMs through sonication. (a) Core-shell structure of LM particles; (b) The influential factors of the LM particle size after sonication; (B) LMs incorporated with metal particles and the main mechanisms. Mechanism 1: Metal particle internalization through sticky LM oxide; Mechanism 2: Metal particle internalization through the formation of metallic bonds; (C) Transformability of LMMPs/LMNPs. (a) Influential factors on the structure of LM particles; (b) Cold-induced transformation and the change of the interfaces between LMs and water. LMs: Liquid metals; LMMPs: LM micro-particles; LMNPs: LM nano-particles.
