Abstract:
... Open-tubular capillary electrochromatography (OT-CEC) is an important tool in separation science due to its effective performance and reusability, and has attracted attention because the coating-process and the coating thickness can be controlled. Although dozens of OT-CEC reviews have been published recently, design of the smart polymer coatings, which can improve the separation efficiency of OT- ...

Abstract:
... Apart from the O releasing at a low rate, large polarization at a high rate is also a big challenge for Li-rich Mn-based oxide (LMO). Prussian blue (PB) with a specific redox potential is regarded as a suitable coating layer to overcome these drawbacks, while its stability is easily destroyed by the intrinsic Jahn–Teller effect after a long run. Herein, Mn vacancy (MV) is introduced into the PB co ...

Abstract:
... Diffusiophoresis is the spontaneous motion of particles under a concentration gradient of solutes. Since the first recognition by Derjaguin and colleagues in 1947 in the form of capillary osmosis, the phenomenon has been broadly investigated theoretically and experimentally. Early studies were mostly theoretical and were largely interested in surface coating applications, which considered the dire ...
