Cellulose, 2013 In the present work, nanofibrillated cellulose (NFC) from bleached eucalyptus pulp was prepared, characterized and used as reinforcement in an unbleached eucalyptus fiber matrix. First, the NFC was fabricated through TEMPO-mediated oxidation and characterized for the degree of polymerization, water retention value, cationic demand and carboxyl content.

Advanced Materials Interfaces, Volume 12, Issue 3, February 3, 2025.Phase change materials (PCMs) can absorb energy during their melting process, whereby heat, for example, is attenuated as it passes through. In this study, a mixture of ethylene glycol distearate (EGDS) and cellulose stearoyl ester (CSE) was used as a PCM in paper without the need for encapsulation.

Ultrasonics Sonochemistry, 2015 Abstract H2O2 was used in the final stage of a multistage bleaching process to increase ISO brightness by 2–3%, because of the poor selectivity and bleachability. However, concerns about the environmental load of the bleaching process have led to the efficient use of oxygen-derived compounds, with a concomitant decrease in the quantity of chlorine ...
