On the Flow Dynamics of Polymer Greases

Lubricants, 2022
In this paper, the flow dynamics of polymer greases was investigated using micro-particle image velocimetry. Polymer greases have a different thickener structure, compared to widely used lithium-based greases, and they have the well-known ability to ...

Review of Thin Lithium Metal Battery Anode Fabrication - Microstructure - Electrochemistry Relations. [PDF]

Adv Mater
Thin, lightweight lithium‐metal anodes are pivotal for practical high‐energy batteries. This review surveys processing routes that convert diverse Li precursors, e.g., ingots, melts, solutions, and vapor, into Li‐rich foils with controlled thickness, areal density, and tailored functionality.
