Abstract:
... The general expression is derived for the diffusiophoretic velocity of a spherical colloidal particle of radius a in a concentration gradient of symmetrical electrolyte. On the basis of this expression, simple approximate analytic expressions for the diffusiophoretic velocity correct up to the order of 1/κa is derived, where κ is the Debye‐Hückel parameter. It is found that the approximate express ...

Herein, we demonstrate a full-inorganic nanoscale flexible memristor by using free-standing ductile α-Ag₂S films as both a flexible substrate and a functional electrolyte. The device accesses dense multiple-level nonvolatile states ...

The insufficient activation of a S/C cathode makes insufficient utilization of S in Li–S pouch cells, while the deep activation of a S/C cathode in a formation process is time-consuming and produces lithium polysulfides, which corrode a Li anode.
