REINFORCEMENT POTENTIAL OF BLEACHED SAWDUST KRAFT PULP IN DIFFERENT MECHANICAL PULP FURNISHES

BioResources, 2009
Bleached unrefined and refined sawdust kraft pulps were added to bleached Norway spruce thermomechanical (TMP) and pressurised groundwood (PWG) pulps in different proportions. Handsheets were prepared and tested for physical properties.

Nickel Foam Electrodes—A Versatile, Powerful, and Readily Available Tool in Electro‐Organic Synthesis

The Chemical Record, EarlyView.
Nickel foam—one material, two faces, and several versatile roles depending on electrolytic conditions. For more than 50 years, nickel foam electrodes have served in electrosynthesis as powerful and readily available electrode materials. Due to their inexpensive nature and easy handling, they have been widely employed.

Sulfuric acid bleaching of kraft pulp 1: Bleaching of hardwood and softwood kraft pulps

Journal of Wood Science, 1999
To develop a new nonchlorine bleaching technology, hardwood and softwood kraft pulps, before and after oxygen-alkali predelignification, were treated with dilute sulfuric acid solutions (pH 1.0-1.8) at 100°C for 1 h and then extracted with aqueous sodium hydroxide at 70°C for l h. Hardwood kraft pulp was successfully bleached.

Electrical Breakdown Analysis of Emerging Oil–Paper Insulation Systems

High Voltage, EarlyView.
ABSTRACT This investigation addresses the effect of particulate additives on the electrical breakdown strength of the oil impregnated insulation paper system. The morphological complexity is addressed by converting data from scanning electron microscope images to a data set suitable for numerical simulation analysis. Then, by using the conventional oil‐

Valorization of Yacon (Smallanthus sonchifolius) peel for peroxidase production and its immobilization on alginate beads for 2,4‐dichlorophenol bioconversion

The Canadian Journal of Chemical Engineering, Volume 104, Issue 8, Page 3984-3995, August 2026.
Sodium alginate was modified with EDC/NHS for the immobilization of Yacon peel peroxidase, resulting in a novel biocatalyst for the oxidation of 2,4‐dichlorophenol. Abstract Yacon (Smallanthus sonchifolius) roots are emerging as an alternative source of peroxidase. This study aimed to extract, immobilize, and characterize the peroxidase from Yacon peel,
