Samples of ball milled cellulose were prepared by ball milling pulps from eucalyptus and softwood (spruce/pine). Water sorption isotherms were obtained by both dynamic vapor sorption and equilibration over saturated salt solutions, in the water content range of 5–42% db (db = dry basis; water as a % age of total solids). Dynamic mechanical analysis using a …
The size and shape of the un-milled and ball-milled Cu 2 S nanoparticles, which are determined by SEM analysis, are presented in Fig. 1.As shown in Fig. 1 (a), the untreated Cu 2 S samples included aggregated bulky particles in the micrometer size. Also, the tendency of the particles to accumulation can be observed for un-milled particles.
To investigate the effect of both ball milling and nano Al 2 O 3 reinforcements on the powders' mechanical properties, the Al and Al-Al 2 O 3 composite ball-milled for 20 h as well as the raw Al powders were separately mounted in carbon-filled phenolic resins. The specimens were polished before micro-hardness testing.
The recovery and utilization of Chinese medicine residue are increasingly becoming a concern. In this study, mulberry waste (a typical Chinese medicine residue) was selected as a raw material for biochar production at different pyrolysis temperatures (300, 500, and 700 °C, representing low, median, and high temperatures). This biochar was then …
