Sheath-core structured Ca-alginate/PVA aerogel fibers via directed freezing wet-spinning

Fucheng Guan et al.

Summary: Biomass-based aerogel fibers have been developed using a directed freezing-assisted forced stretching strategy to overcome their disadvantages of low mechanical strength, poor long-range order, and easy combustion. The Ca-alginate/polyvinyl alcohol (Ca-A/PVA) aerogel fibers with long-range-ordered pores exhibit excellent comprehensive mechanical properties. The strategy presented in this study is also applicable to other alginate-based aerogel fibers.

Adsorption of Dyes from Wastewater: A Comprehensive Review

Rishabh Agarwala et al.

Summary: Dyes are significant water pollutants due to their wide industrial usage, and adsorption is an effective method for removing color from contaminated water. The rapid industrialization in the twenty-first century has led to the use of more noble colors and dyes, contributing to various forms of pollution, including water, soil, and air pollution. This report aims to discuss the chemical and bio-based adsorbents used for removing different types of industrial dyes, investigating various adsorption isotherm assumptions and mathematical formulations, and addressing the influence of different factors on adsorption phenomena.

Selectively Producing Acetic Acid via Boric Acid-Catalyzed Fast Pyrolysis of Woody Biomass

Xueli Hou et al.

Summary: Boric acid has been proven to be an effective catalyst in the pyrolysis of woody biomass, leading to higher initial degradation temperatures and increased residual carbon contents, while decreasing the maximum weight loss rates. It also significantly alters the composition and distribution of volatile pyrolysis products, increasing small molecule compounds like acetic acid and furfural, while decreasing high molecular weight phenol derivatives. These effects are more pronounced at higher temperatures, with acetic acid content increasing up to 14 times higher than untreated wood flour when the boric acid to wood flour mass ratio is 2.
