CHARACTERIZATION AND SIMULATION OF MACROSCALE MOLD-FILLING DEFECTS IN MICROMINIATURE POWDER INJECTION MOLDING

open access: yes, 2019
While micromolding with polymers has met with success, material homogeneity remains a critical issue in powder injection molding (PIM) because separation of the powder and binder results in defects in metal or ceramic microparts.

Comparative Analysis of Metal Preloading Technologies in Batteries and Capacitors

open access: yesEcoEnergy, EarlyView.
Metal preloading strategies play an important role in efficient batteries and hybrid capacitors to compensate for the consumed metals at the first discharge. This article reviews recent progress in preloading technologies in lithium‐ion and other metal‐ion systems.

ON A NOVEL METHOD OF INCORPORATING AN INTERNAL STRUCTURE INTO GREEN POWDER METALLURGY COMPACTS USING DIE COMPACTION

open access: yes, 2012
A novel method of producing die compacted powder metallurgy components with fully en-closed internal structures was developed. The physical characteristics of the compacts were evaluated by measuring bulk density, internal density gradients and ...

Unraveling Synergistic Regulation Mechanism in Nitrogen/Sulfur Co‐Doped Biomass‐Derived Hard Carbon Toward Durable Sodium‐Ion Battery Anodes

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Nitrogen/sulfur co‐doping optimizes the electron and spatial structure of biomass‐derived hard carbon, and the anode demonstrates superior long‐term cycling stability over 2000 cycles, validating an improved “adsorption‐intercalation‐pore filling” mechanism.
