Photophysical properties of ball milled silicon ...

In this study, we have used high-energy ball milling in an inert gas atmosphere to synthesize SiNCs and study their photophysical properties. The induced accumulation of high strain, quantum confinement and possibly also impurities in the SiNCs resulted in visible light spectrum PL at room temperature.

Magnetic and magnetocaloric properties of ball milled

2020-6-1  3 by ball milling has been studied by investigating the change in the magnetic and magnetocaloric properties. Ball milling is found to enhance the strength of the ferromagnetic component. An analysis based on the Arrott plots shows clear difference in the critical exponents between the bulk and the ball milled samples.

Enhanced electrochemical properties of ball-milled γ′

2021-1-15  The specific morphology of the ball-milled BM-30 γ′-V 2 O 5 powder, made of small aggregates lower than 500 nm with mean crystallite size of 35 nm, promotes a uniform sodiation of γ′-V 2 O 5 host lattice. As major consequence, the charge efficiency is greatly improved to around 90%, allowing excellent cycling properties to be achieved.

Powder properties of hydrogenated ball-milled graphite

Ball milling is an effective way of producing defective and nanostructured graphite. In this work, the hydrogen storage properties of graphite, ball-milled in a tungsten carbide milling pot under 3 bar hydrogen for various times (0-40 h), were investigated by TGA-Mass Spectrometry, XRD, SEM and Laser Diffraction Particle Size Analysis. For the conditions used in this study, 10 h is the optimum milling
