The altered physical, thermal and optical characteristics of Paulownia biomass after pretreatment of ultrafine grinding were compared with well-studied biomass of corn stover. Microstructural, FTIR and TGA analysis highlight the deterioration of crystal structure and lignin breaking of cellulose with increase in pretreatment time, which significantly improves hydrolysis and enhances hydrogen production subsequently.
2020-10-1 In comparison to other methods, ultrafine grinding provides several advantages including particle densification, enzymatic accessibility, high surface area, higher bioconversion with minimum hazards to environment (Yadav et al., 2019).

2009-5-15 At Grinding 1–4, ultrafine particle fractions between 63 and 84 number-% were found and relatively low median number concentrations compared to the other job activities in this study (15 × 10 3 to 23 × 10 3 cm −3). The low median concentration of particles may be due to a relatively low frequency of grinding activities at these sites at
