Hydrogen uptake during the mechanochemistry of lithium nitride under 9 MPa hydrogen pressure has been analyzed by means of in situ solid-gas absorption and ex situ X-ray diffraction (XRD) measurements. In situ hydrogenation curves show two H-sorption steps leading to an overall hydrogen uptake of 9.8 wt% H after 3 hours of milling. The milled end-products consist of nanocrystalline (∼10 nm) LiN...

Ni(Mg)Al-layered hydroxides with molar ratios of (Ni + Mg)/Al = 2, 3, 4 and Ni/(Ni Mg) 0.1, 0.3, 0.5, 0.7 were synthesized by mechanochemical activation. It has been proven that the phase composition samples was presented a single hydrotalcite up to 0.5. For first time, catalysts based on prepared route have studied in reaction furfural hydrogenation. The correlation between conversion, selecti...

Previous studies demonstrated the macroscale wear behavior of soda lime silicate (SLS) glass in humid air was governed by mechanochemical reactivity sliding interfaces, which is a function relative humidity (RH). In this study, it observed that no disenible nanowear SLS surface dry conditions because contact elastic. conditions, occurred due to water-induced reactions and RH dependence above 20...
