The structural and magnetic evolution in copper ferrite (CuFe2O4) caused by high-energy ball milling are investigated by x-ray diffraction, Mössbauer spectroscopy, and magnetization measurements. Initially, the milling process reduces the average grain size of CuFe2O4 to about 6 nm and induces cation redistribution between A and B sites.

ÄGmon°HS - DTIC

Synthesis of ZrNiSn by mechanical alloying. Mechanical alloying (or ball-milling) is being explored as an alternate synthesis method for half-Heusler alloys. This technique, in which elemental constituents are placed in a high-energy ball mill in an inert atmosphere, eliminates the high temperature processing (melting, arc melting).

It can be used for wet or dry milling. Standard ball milling is performed by rotating the chamber around a horizontal axis. High energy ball milling involves a second, larger chamber in which the smaller agitates, sloshing the contents via centrifugal force. Both types of ball milling can be performed in batches or continuous operation.

High- and Low-Energy Emulsifications for Food Applications: A ...

High-energy emulsification is traditionally used to produce food-grade emulsions. However, energy input, design of the device and the type of surfactant should be carefully evaluated to achieve the desired emulsion properties. The low-energy processes, as spontaneous emulsification and phase inversion temperature, are alternative methods for producing systems with high stability and smaller ...
