Aug 24, 2009· To reduce the recalcitrance and enhance enzymatic activity, dilute H2SO4 pretreatment was carried out on Alamo switchgrass (Panicum virgatum). Ball-milled lignin was isolated from switchgrass before and after pretreatment. Its structure was characterized by 13C, HSQC, and 31P NMR spectroscopy. It was confirmed that ball-milled switchgrass lignin is of HGS type with a considerable …

Three alloys are prepared through mechanical alloying and the hydrogen storage properties have been investigated systematically. In Mg-Ni and Mg-Ni-Fe alloys, the main binary alloy phase is Mg2Ni, while in Mg-Ni-Fe-Ti alloys, NiTi, FeTi are also found as the main binary phases beside Mg2Ni. The hydrogen absorption capacities of the three alloys are 2.9wt%, 2.2wt% and 2.3wt% respectively.

ABSTRACTThe microstructure of high-temperature metals such as Ti, Ni, and Cr can be modified using ceramic nanoparticles to form metal matrix nanocomposites (MMNCs). Such materials are generally prepared via powder metallurgy routes. In this study, 25 wt% SiCnp and Al2O3np were separately ball milled as a reinforcement of Ti, Cr, and Ni matrices to investigate their effects on the phase ...

Aug 17, 2005· Effect of ball-milled treatment done by high-frequency oscillatory-type mill for different time on structure and antiobesity of konjac flour was investigated. Konjac flour granules became smoother and remained its original shape in the first 1.5 h treatment, however its grain size changed from 657.3 (d50) to 23.7 μm (d50) after 4 h treatment, which meant that the pulverized model of konjac ...

Ball milling was performed with a Spex 8000 mill with hardened steel vial and balls. The temperature obtained during cryo-milling was estimated to be 85 K by Klassen et al. . Thereafter we refer to this temperature as LN2. The powders were first pre-alloyed by milling at room temperature for 24 h, and then milled for 5 h at low temperature.

The ball milling was performed in a high-energy planetary mill (Retsch PM 400) at room temperature under compressed air. Stainless steel milling jars (250 mL) containing an appropriate mass of balls (15 mm) of the same material. One gram of SQVM was milled for 1, 3, 15, 30, 50, and 60 h in each jar with a ball/sample weight ratio of 30:1.
