Oxidative coupling of methane (OCM) is a promising method for the direct conversion of methane to ethene and ethane (C 2 products). Among the catalysts reported previously, Mn 2 O 3-Na 2 WO 4 /SiO 2 showed the highest conversion and selectivity, but only at 800° to 900°C, which represents a substantial challenge for commercialization. We report a TiO 2-doped Mn 2 O 3-Na 2 WO 4 /SiO 2 ...

A rapid method for preparing amorphous alloys has been developed utilizing a SPEX high energy ball mill. Parameters such as ball size, mass of balls and milling time, were systematically optimized to prepare amorphous alloys quickly. Amorphous alloys previously not thought possible to synthesize by means of SPEX milling were made amorphous by the new method. . When applied to …

Using data collected between 1997 and 2014 by NASA's Program for Arctic Regional Climate Assessment and Operation IceBridge (), in combination with 1600 km of new airborne radar data collected in May 2016 (Supplementary Materials and Methods), we identified a large circular depression in the bed topography of the Greenland Ice Sheet ().This structure is covered by up to 930 m of ice …
The NCS particle size was controlled by the mechano ball mill technique using a ball-to-weight ratio of 1:5 and the process was implemented out for 48 h at 60 °C (with all moisture removed). Interestingly, the mechano ball mill process produced precise NCS particles with sizes of approximately 1258 μm and 208 m at volume percentages of 22 and ...
Glass frit was ground in a Ball mill to produce particles with a size distribution ranging from 3.3 to 30.5 μm and D 50 = 10.8 μm was used (measured by a Malvern Mastersizer 2000, Malvern Instruments Ltd. UK). Inks for 3D were produced with a 25 wt% Pluronic F-127 solution (CAS: ) and mixed with glass particles (47.5 vol ...

Graphene has been proven to be a promising material for various applications due to its outstanding chemical, physical, optical as well as mechanical properties. To further improve these properties of graphene, here we apply a grinding method with various speeds (100–600 rpm) …
This paper presents results of the research of micronization grinding of dry mica in a planetary ball mill. Investigation was conducted in order to improve the quality and to obtain clearly defined properties and characteristics of mica powder. The micronization grinding of dry mica was performed in four time periods: 30, 60, 120, and 360 minutes.
It is worth mentioning that the dry ball milling method is quite general. By ball milling graphite with Cl 2, Br 2, and I 2, a series of edge-selectively halogenated GnPs (XGnPs, X = Cl, Br, I) have been prepared . Although the electron negativities of halogen atoms are in the order of Cl (x = 3.16) > Br (x = 2.96) > I …

In this study, we investigate the influence of in situ reactive synthesis of Ti6Al4V- AlCoCrFeNiCu high entropy alloys by laser metal deposition on the microstructural and mechanical properties of the as-built alloy as opposed to the traditional method of mixing powders via a ball mill prone to contamination and segregation. We explore the capability of a new alloy design by …
The strong electrostatic interaction between Al 3+ and close-packed crystalline structures, and the single-electron transfer ability of traditional cationic redox cathodes, pose challenged for the development of high-performance rechargeable aluminum batteries.

Planetary ball mill is a high-energy ball mill. The ratio of the speed of the rotating disk (jar holder) and the grinding jar is 1:2, which means that when the rotating disk rotates once, the grinding jar rotates in the opposite direction for two cycles (Broseghini, D'Incau, Gelisio, Pugno, & Scardi, 2016 ).
