Unlocking Ultra‐Long Cycle Stability of Li Metal Electrode by Separators Modified by Porous Red Phosphorus Nanosheets

Advanced Functional Materials, EarlyView.
Coating the standard polypropylene separator with a porous red phosphorous nanosheet greatly improves cycling performance in Li electrode cells. The phosphorus‐based surface chemistry deactivates electrolyte solvent decomposition and enhances the cleavage of F‐containing salt, resulting in an inorganic‐dominated electrolyte interphase (SEI) composition

Nanoscale grains, high irreversibility field, and large critical current density as a function of high energy ball milling time in C-doped magnesium diboride

, 2007
Magnesium diboride (MgB2) powder was mechanically alloyed by high energy ball milling with C to a composition of Mg(B0.95C0.05)2 and then sintered at 1000 C in a hot isostatic press. Milling times varied from 1 minute to 3000 minutes.

Low-Temperature Rapid Synthesis and Superconductivity of Fe-Based Oxypnictide Superconductors

, 2010
we were able to develop a novel method to synthesize Fe-based oxypnictide superconductors. By using LnAs and FeO as the starting materials and a ball-milling process prior to solid-state sintering, Tc as high as 50.7 K was obtained with the sample of Sm ...

Effects of Ball Milling on the Structure and Foaming Properties of Soy Protein Isolate

Shipin gongye ke-ji
To enhance the foaming properties of soy protein isolate (SPI), SPI was subjected to ball milling at varying ball-to-material ratios (8:1, 14:1, and 20:1) for 150 min at a rotational speed of 96 r/min, using untreated SPI as a control.
