Ball milling synthesis of covalent organic framework as a highly active photocatalyst for degradation of organic contaminants.

Journal of Hazardous Materials, 2019
Facile, environmentally-friendly fabrication of high-yield and stable covalent organic framework (COF) materials has been a limitation to their large-scale production and application.

Multifractal properties of ball milling dynamics

Chaos: An Interdisciplinary Journal of Nonlinear Science, 2014
This work focuses on the dynamics of a ball inside the reactor of a ball mill. We show that the distribution of collisions at the reactor walls exhibits multifractal properties in a wide region of the parameter space defining the geometrical characteristics of the reactor and the collision elasticity.

Dry ball milling and wet ball milling for fabricating copper–yttria composites

Rare Metals, 2018
Abstract Yttria‐reinforced copper matrix composites were prepared by dry ball milling (DBM) and wet ball milling (WBM), respectively, followed by spark plasma sintering (SPS). It is to determine which milling process is better for fabricating Cu–Y 2 O 3

Mechanochemical decomposition of pentachlorophenol by ball milling

Journal of Environmental Sciences, 2009
The mechanochemical dechlorination of pentachlorophenol (PCP) was studied using CaO and SiO2 powder as additives. The effects of the milling time and additives on the dechlorination rate were investigated. The resulting product was characterized by X-ray diffraction (XRD), Fourier transform infrared spectra (FT-IR), thermogravimetric analysis (TG) and ...

Mechanochemical deconstruction of lignocellulosic cell wall polymers with ball-milling.

Bioresource Technology, 2019
In this work, the deconstruction mechanism of corn stover cell wall polymers during ball milling was evaluated. The characterization showed that ball milling not only brought about the dissociation of the cross-linked cellulose-hemicellulose-lignin ...

Effects of wet and dry ball milling on the physicochemical properties of sawdust derived-biochar

, 2020
Ball milling has been used as a green method for the modification of biochars in recent years. Therefore, the effects of physicochemical properties of biochars derived from sawdust via dry and wet mechanical ball milling and hand lapping were integrally ...

Microstructure investigations of ball milled materials

Microscopy Research and Technique, 1998
HREM and FEG TEM were emphasized and extensively used to follow the most subtle changes in the structure and composition of ball-milled Cu, Fe-Cu, and thermally decomposed Fe60Cu40. Some significant results are obtained and summarized as follows: HREM shows that the deformation of ball-milled copper proceeds mainly by twinning and shear bands (SBs ...

Process engineering with planetary ball mills

Chemical Society Reviews, 2013
Planetary ball mills are well known and used for particle size reduction on laboratory and pilot scales for decades while during the last few years the application of planetary ball mills has extended to mechanochemical approaches. Processes inside planetary ball mills are complex and strongly depend on the processed material and synthesis and, thus ...
