Arundo donax L. reed: New perspectives for pulping and bleaching. 5. Ozone-based TCF bleaching of organosolv pulps [PDF]
Bioresource Technology, 2008 Three selected alkali-based organosolv pulps (alkali-sulfite-anthraquinone-methanol (ASAM), alkali-anthraquinone-methanol (organocell) and ethanol-soda) from agrofibre crop giant reed (Arundo donax L.) were bleached by an ozone-based TCF (totally chlorine- free) bleaching sequence AZE(R)QP (where A is an acidic pulp pre-treatment, Z is an ozone stage, (

Ozonolysis of Lignin: From Extensive Degradation to Selective Ring-Opening Oxidation. [PDF]
ChemSusChemDespite its potential as a renewable feedstock, lignin, a major component of plant cell walls and a by‐product of the pulp and paper industry, has long been underutilized. Historically, pulp mills employed ozonolysis, a powerful oxidative process, to delignify cellulosic fibers and break down lignin.

Effect of pulping and bleaching on pulp carbohydrates and technical properties
, 1996 Pulping and bleaching have a profound effect on the carbohydrate chem. of kraft pulps. The chem. structure of xylan is modified due to the conversion of methylglucuronic acid side groups to hexenuronic acid side groups.

Sequential changes in cellular properties accompanying amniote somite formation
Journal of Anatomy, Volume 242, Issue 3, Page 417-435, March 2023., 2023 The process of epithelialization that culminates in the formation of somites begins very early in the pre‐somitic mesoderm, in defined order, starting dorsally, then medial and ventral, then lateral and finally the somite buds off – this challenges assumptions made by most models of somitogenesis.

Synergism of enzymes in chemical pulp bleaching from an industrial point of view: A critical review
The Canadian Journal of Chemical Engineering, Volume 101, Issue 1, Page 312-321, January 2023., 2023 Abstract Enzymes are biological catalysts and are very specific, catalyzing either a single chemical reaction or a limited number of closely related reactions. For example, xylanases are enzymes that catalyze the cleavage of polymeric xylan and thereby break down this hemicellulose.

Conditional ablation of E‐cadherin in the oral epithelium progeny results in tooth anomalies
Clinical and Experimental Dental Research, Volume 8, Issue 5, Page 1185-1191, October 2022., 2022 Abstract Objectives The objective of this study is to confirm the developmental origin of the enamel organ and evaluate the role of E‐cadherin in tooth development by conditional deletion in the oral epithelium and its enamel organ progeny. K5‐Cre;ROSA26 compound mice were included in this study in order to confirm the oral epithelial origin of the ...
