Ball milling (BM) is a wellestablished technique for producing different materials in powder shape. Dynamical analysis of BM helps to optimize the process through simple but general relations (, definition of an equivalent milling time). Concerning the field of study of magnetocaloric effect (MCE), BM is used in different ways: as a single step process (mechanical alloying), as an initial ...

Ballmilling is a lowcost and green technology that offers mechanical actions (shear, friction, collision, and impact) to modify and reduce starch to nanoscale size. It is one of the physical modification techniques used to reduce the relative crystallinity and improve the digestibility of starch to their better utility.

Synthesis of Li ion battery materials via ball milling has been a huge area of growth, leading to new highcapacity electrode materials, such as a number of promising disordered rocksalt (DRS) phases. In prior work, it was generally assumed that the synthesis was facilitated simply by local heating effects during the milling process.

Mechanical ballmilling is a commonly used method to shattering crystals or introducing defects in carbon materials. But herein, we observe that the highly porous and disordered carbon lattice of activated carbon is converted to graphitic structure during ballmilling, along with the introduction of oxygen in the bulk phase.

The cycling mechanism of Li2MnO3 cathode materials synthesized by conventional solidstate methods at high temperatures (800900 °C) has been intensively investigated. Previous studies showed that CO2 and O2 gas evolution accounts for most of the charge capacity, followed by some Mn reduction during discharge. In this work, we analyze the effects of ball milling on the structure, surface ...
