Carbon fibers are routinely prepared using petroleum-based precursor fibers. To proceed toward a more sustainable method of production, cellulose has been utilized as an alternative carbon source. In this work, were manufactured from deacetylated acetate through pyrolysis. First, filaments continuously spun by wet spinning, followed deacetylation. The resulting carbonized without any carbonization agents. Considering the use regenerated fibers, with surprisingly high mechanical strength achieved in continuous pyrolysis process at 1400 °C under nitrogen atmosphere. Fibers showed diameters below 10 μm, tensile strengths, and Young's moduli up to 0.9 90 GPa.

The control of alumina morphology is crucial yet challenging for its various applications. Unfortunately, traditional methods preparing particles suffer from several limitations such as irregular morphology, poor dispersibility, and restricted application areas. In this study, we develop a novel method spherical mesoporous using chitin Pluronic P123 mixed templates. effects reaction temperature, time, the addition templates on phase structure, micromorphology, optical absorption properties samples were investigated. experimental results indicate that lower temperature shorter time facilitated formation with excellent CO2 adsorption capacity. periodic density functional theory (DFT) calculations demonstrate both (110) (100) surfaces γ-Al2O3 can strongly adsorb CO2. difference in amount adsorbed by Al2O3 mainly due to different surface areas, which give numbers exposed active sites.
