Graphite functionalization by ball milling with sulfur
2019年1月18日 After short-term milling (e.g., after 10 min, blue curves in Fig. 1A, B) 002 and 004 reflections, corresponding to crystal planes parallel to the graphitic planes, become definitely more intense than for the starting graphite (black curves in Fig. 1A, B). This result can be rationalized by considering that short term milling induces an orientation of
Ball Milling an overview ScienceDirect Topics
Compared to this, DBM requires several milling agents e.g. sodium chloride (NaCl) [30], Melamine (Na 2 SO 4) [31,32] etc., along with the metal balls to reduce the stress induced in graphite microstructures, and hence require additional purification for exfoliant's removal. Na 2 SO 4 can be easily washed away by hot water [19] while ammonia-borane (NH 3 BH

Formation of amorphous state by ball milling and
2020年4月5日 E-mail: [email protected] Abstract. Formation of Al 50 Ti 50, Al 50 Ti 45 Ni 5 and Al 50 Ti 40 Ni 10 amorphous alloys by ball milling and their mechanical crystallization upon further milling have been investigated. Ni addition improves the thermal stability and increases the strength of the powder compacts obtained by hot pressing. 1. Introduction
Ball milling pretreatment of corn stover for enhancing the
The optimum parameters for the milling process were ball speed of 350 r/min, solid/liquid ratio of 1:10, raw material particle size with 0.5 mm, and number of balls of 20 (steel ball, Φ = 10 mm), grinding for 30 min. In comparison with water milling process, alkaline milling treatment could increase the enzymatic hydrolysis efficiency of corn
Ball-milling synthesis of ultrafine Na y Fe x Mn 1-x [Fe(CN)
2019年12月18日 In this work, a facile ball-milling method is used to synthesize the ultrafine Na y Fe x Mn 1-x [Fe(CN) 6] without additional additives. It shows that the ultrafine particles (~ 50 nm) favor the fast Na + diffusion in MnPBA, while Fe-doping can enhance the electrical conductivity and suppress the structure distortion upon Na + insertion/extraction.
