Summary: The degradation of cellulose significantly impacts the mechanical, optical, physical, and chemical properties of paper, affecting its longevity. Analytical techniques such as size-exclusion chromatography and spectroscopy are used to evaluate the degradation processes, particularly in papers containing lignin. Humidity was found to alter cellulose chain lengths, with high lignin content suppressing some degradation pathways. This knowledge can guide the development of strategies and chemical treatments to prevent paper aging.

Summary: The trend of replacing petroleum-based products with sustainable alternatives has led research efforts to focus on plant-based materials like cellulose nanocrystals (CNCs). A novel surface modification method was introduced to tune CNC properties by depositing cellulose phosphate oligosaccharides during production, resulting in improved surface charge densities, water adsorption capacities, and viscosities. This study presents an easily scalable modification route for CNCs, offering potential for expanded functionality and applications.

Summary: This paper discusses a new approach of obtaining microfibrillated cellulose with low degree of polymerization through sulfuric acid hydrolysis with simultaneous ultrasonic treatment under mild conditions. The resulting microfibrillated cellulose retains the structure of cellulose I and has high stability and thermal stability. The simultaneous hydrolysis process with ultrasonic treatment reduces the number of stages, energy costs, and expands the scope of applications.

Summary: Gasification kinetics of six chars from residual origin were studied under relatively low temperature, low CO2, and high H2O partial pressures. The Random Pore Model (RPM) showed the best fit to experimental results, but the selection of the reaction model depended on the ash composition, specifically the presence of alkali and alkaline earth metals. Chars with ash content higher than 30% wt. were modeled with the RPM model, while chars with the highest K/Si ratio required modified versions of the RPM to accurately predict reaction rates. Textural properties played a key role in determining reaction parameters, such as the pre-exponential factor and activation energy, for chars with similar ash content and composition.

Summary: This paper studies the thermal stability and decomposition of cork materials with and without silica aerogel filler. The results show that the decomposition is inhibited and the pyrolysis is significantly reduced with the addition of silica aerogel. This finding suggests that silica aerogel-infused cork may be a promising raw material for biofuel production with reduced environmental pollution.
