Manipulating small-volume liquids is crucial in natural processes and industrial applications. However, most liquid manipulation technologies involve complex energy inputs or non-adjustable wetting gradient surfaces. Here, a simple and adjustable 3D liquid manipulation paradigm is reported to control liquid behaviors by coupling liquid-air-solid interfacial energy with programmable magnetic fields.

Water evaporation is a ubiquitous and spontaneous phase transition process. The utilization of solar-driven interface water evaporation that simultaneously obtains clean water and power generation can effectively alleviate people's concerns about fresh water and energy shortages. However, it remains a great challenge to efficiently integrate the required functions into the same device to reduce the complexity of the system and alleviate its dependence on solar energy to achieve full-time operation.

This work reports a covalent organic framework composite structure (PMDA-NiPc-G), incorporating multiple-active carbonyls and graphene on the basis of the combination of phthalocyanine (NiPc(NH ) ) containing a large π-conjugated system and pyromellitic dianhydride (PMDA) as the anode of lithium-ion batteries. Meanwhile, graphene is used as a dispersion medium to reduce the accumulation of bulk covalent organic frameworks (COFs) to obtain COFs with small-volume and few-layers, shortening the ion migration path and improving the diffusion rate of lithium ions in the two dimensional (2D) grid layered structure. PMDA-NiPc-G showed a lithium-ion diffusion coefficient (D ) of 3.

Functional phase-change materials (PCMs) are conspicuously absent in various organic or inorganic solids with diversified applications in which the attributes of these molecular materials have been highly realized. Leakage problem during the phase transition process is the main obstacle on the way of widely use of solid-liquid PCMs who has been recognized to be promisingly practical candidates for energy storage owing to the high energy storage density and small volume change in the phase transition process. Herein, a novel homogeneous-to-heterogeneous-strategy, in which all the starting materials involved display a homogeneous state and the encapsulation framework formed in situ in the encapsulation process, enabled by an aerogel reaction of silica was realized under the catalysis of an organic base.
