Integrated Approach for Bioethanol and Paper Production using Populus deltoides Wood Biomass: An Experimental Study

open access: yesAgroEnvironmental Sustainability, 2023
Lignocellulosic materials contain two major sugar macromolecules, cellulose and hemicellulose, and polyphenolic lignin. During pulping, lignin and hemicellulose are broken down into smaller molecules such as organic acids, and removed in the black ...

Edible additives & cellulosic paper [PDF]

open access: yesBioResources, 2020
Assembly of biofibers into paper-based products fits well into green chemistry principles. Biobased additives such as cationic starch and carboxymethyl cellulose are widely used in the paper industry. Edible additives, which often can be regarded as “safer” than regular biobased additives, may also play a role in tailorable design of paper-based ...

Synthesis and adsorption performance of functionalized chitosan and carboxyethylsilanetriol hybrids

open access: yesBMC Chemistry, 2023
A novel adsorbent from cationic chitosan derivative and anionic silica precursor was fabricated to remove methylene blue (MB). The hybrid material was prepared from N-guanidinium chitosan acetate (GChi) and carboxyethylsilanetriol sodium salt by a simple
