The analysis results show that a uniform MnO 2 coating layer can be formed on the surface of the Fe particles via low speed ball milling with agate balls. When the MnO 2 content increases from wt% to wt%, the thickness of the MnO 2 coating layer exhibits a growth trend.

Section snippets Preparation of catalysts. MoS 2 was put in a planetary ballmilling machine within steel vessel. The machine was operated at 425 rpm and the rotation direction changed every 30 min. To evaluate the influence of ballmilling time, g commercial MoS 2 was blended with 100 g balls for 0, 1, 2, 5 h and named 0MoS 2, 1MoS 2 2MoS 2, and 5MoS 2, respectively.

Research highlights. Phase transformation of MgSn system during ball milling was investigated. It was found that solubility extension of Sn in Mg by milling is not feasible due to the preferential formation of Mg 2 Sn. But the formation of Mg 2 Sn facilitates the grain refinement of Mg. The microstructure and hydrogen storage properties of MgSn nanocomposite were studied in detail.

A rapid ( h) onestep ball milling (BM) method was developed not only to modify commercial MnO2 via topdown approaches (BM0), but also to bottomup synthesize MnOx by cogrinding of KMnO4 and MnC4H6O4 (BM1) or KMnO4 and MnSO4 (BM2). Catalysts activity on gaseous POPs removal was tested using hexachlorobenzene (HCBz) as surrogate. Catalytic performance decreases in the order of BM2 ≈ BM1 ...

The NanoPulverizer NP100 is a type of planetary ball mill (planetary mill) or bead mill. Beads, known as introduce balls, are grinding media into a grinding container together with slurry. This container then revolves at a high speed, clockwise, with a 45° tilt angle, while at the same time rotating counterclockwise (see "Mixing"). Refer ...

mechanical ball milling is more thermally stable. Furthermore, the dramatic weight loss after 230 °C shows the significant loss of PEI. This is mainly due to the decomposition of the amino group. In summary, the TGA results show the good thermal stability of ballmilled adsorbents. The FTIR spectra of the adsorbents are shown in Figure 5.
