Impact of various reaction conditions of solvothermal synthesis on electrochemical properties of Ni-MOF materials.

A series of Ni-MOF materials were synthesized by a one-step solvothermal method under different reaction conditions, including metal source, organic ligand, reaction time and reaction temperature. The results demonstrated that the Ni-MOFs synthesized with Ni(NO3)2•6H2O as the metal source had higher crystallinity and a more uniform crystalline structure than those with NiCl2•6H2O. Different organic ligands led to the formation of Ni-MOFs in various morphologies.

Multifunctional triple-network ionic hydrogel sensors engineered by Al/Zn bimetallic salt solution: From cellulose solvent to conductive network architecture.

Ionic conductive hydrogels show promise for flexible sensors in wearables and e-skins, but balancing mechanical strength with high conductivity remains challenging.
