Oct 24, 2008 The effects of particle size of activated carbon AC on its wettability, electrode coating technology and electric chemical performance were studied to assemble nonaqueous electric double layer capacitors EDLCs for high power requirements. The results show that the specific surface area and total pore volume of AC decrease from 2 137 m2g to 1 683 m2g, and 0.95 cm3g to 0.78 cm3g ...
Oct 30, 2014 Ball milling as a mixing technique for UHMWPE based composites is not a new approach but yet, the effect of time, rotational speed, loading of milling jar, and type of ball mill has not been reported properly for UHMWPE. Composites with 0.5 and 1.0 wt UHMWPEMWCNTs were manufactured with different rotational speed and mixing times.
The effect of ball milling on the morphology of multiwall carbon nanotubes MWCNT is studied. Moderate ball milling intensity generates a good yield of open tips with minimum damage to the tubular structure. The open tips exhibit symmetrical or asymmetrical morphology, depending on how they are generated. A symmetrical and round morphology is characteristic for most of the closed tips ...
Oct 29, 2019 Iron- and nitrogen-doped carbon-based catalysts are one of the most promising alternatives to platinum-group metal-based ones currently used in the fuel cell industry. Here, we study the effect of ball-milling conditions and compositions of catalyst precursors comprising a silicon carbide-derived carbon CDC on the properties of the final catalysts, most importantly their activity toward the ...

Activated carbon AC with a very high specific surface area of 3000 m2 g1 and a number of course particles average size 75 m was pulverized by means of planetary ball milling under different conditions to find its greatest performances as the active material of an electric double-layer capacitor EDLC using a nonaqueous electrolyte.
Easy method to prepare N-doped carbon nanotubes by ball. Sep 01, 2015 N-doped carbon materials are promising metal-free catalysts for a number of applications. In this work, a cost effective and easy method to prepare N-doped carbon nanotubes by ball milling was developed, which avoids the use of solvents and production of wastes.
This paper focuses on the optimization of ball milling as a dry mixing method and comparison with the wet method for manufacturing phenolicmulti-wall carbon nanotube MWCNT composites. In the ball milling, the effect of milling-time on the properties of composites containing functionalized and pristine MWCNT in two MWCNT concentrations has been investigated.
Apr 10, 2012 Low-cost, high-yield production of graphene nanosheets GNs is essential for practical applications. We have achieved high yield of edge-selectively carboxylated graphite ECG by a simple ball milling of pristine graphite in the presence of dry ice. The resultant ECG is highly dispersable in various solvents to self-exfoliate into single- and few-layer 5 layers GNs.
Abstract. In this paper, to improve the poor wettability between the Carbon nanotubes CNTs and metal matrix, the mechanical alloying MA technique by the ball milling method was employed. Also, the CNTs were pre-coated to improve the agglomeration of the CNTs with copper powder. The main aim of this work is the fabrication of Cu-CNT nanocomposite powder using the MA by ball milling.
