“…In the study of Liu et al (2021), it provides insights into the manufacturing techniques for cellulose-based composite foams and aerogels, combined with diverse active components, cellulose materials, serving as the foundational building blocks, are integral to the foams and aerogels' composition. Furthermore, the concentration of the cellulose acetate fibers affects the shape and density of the cellulose acetate aerogel foam (Chua et al, 2020). Active materials, often on the nanoscale, like carbon nanotubes, graphene, or metal nanoparticles, are incorporated to enhance electrical conductivity.…”

This study presents a comprehensive evaluation of the efficacy of infusing thermal insulator powder into cellulose acetate aerogel foam to enhance both the production process and its thermal insulation performance, with a focus on the impact of varying concentrations of thermal insulator powder on the structural and mechanical properties of CAAF, compared to commercially available aerogel foams. The researchers used true experimental quantitative design that allowed them to have precise control over variables, particularly the amount of thermal insulator powder. This method helped establish causal relationships and assessed the impact of the powder on foam properties, particularly thermal insulation. Findings indicate that there is a significant difference in the commercial aerogel foam, cellulose acetate aerogel foam, and cellulose acetate aerogel foam infused with different concentrations of thermal insulator powder in terms of their thermal conductivity and time longevity. However, the results indicated that the infusion of thermal insulator powder did not significantly enhance the physical stability property of the samples.

Microstructure of the materials is essential to design new functional materials, especially from atomic scale to micron order structures. Many attempts have been carried out to give nanostructures and such structures have been analyzed using cutting-edge methods both theoretically and experimentally. In this report, recent trends in research on functional materials related to the micro-structures in nano-meter scale are reviewed by mainly introducing the contents of the special issue published in Materials Transactions, vol. 61, No. 8, in which following 6 categories of the topics are included; computational materials science, magnetic materials, advanced functional oxides, carbon and organic materials, and optical materials.

Understanding the adsorption of the smoke stream (SR) on cellulose acetate stick as cigarette filter with different temperatures is beneficial for controlling chemical emissions and reducing the toxic effect of smoking on human health. However the investigation of corresponding adsorption properties was missing because the adsorption of smoke stream (SR) on cellulose acetate stick is sensitive with the threedimensional temperature gradient. In this work, the adsorption of typical smoke stream substances, such as CO, propylene glycol, formaldehyde, and acetone, on cellulose acetate stick were studied by in-situ diffuse reflectance Fourier transform infrared spectroscopy with different temperatures assisted by the infrared thermal imaging method. The adsorption capacities of cellulose acetate stick to these typical smoke stream substances is dependent on the adsorption time and temperature. The adsorption properties all fitted well with the Freundlich model. By a spectroscopic and mathematical explanation, quantifying contours of adsorption was performed. The 3D model of the normalized CO adsorption of cellulose acetate stick versus the spatial coordinates and time was established. This study gives unparalleled insight into smoking release characteristics of tobacco filtered by cellulose acetate and regulating cellulose acetate stick for reducing the negative effect of smoke on human health.
