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

open access: yesBioResources, 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.

Board That Transforms: Relationship Between Board Structure and Environmental, Social, and Governance Performance in BRICS Countries

open access: yesCorporate Social Responsibility and Environmental Management, Volume 33, Issue 3, Page 3660-3682, May 2026.
ABSTRACT The purpose of this study is to examine the relationship between board composition characteristics and ESG performance in companies from BRICS countries, and to assess how sector sensitivity moderates this relationship. A sample of 2045 BRICS companies was examined using panel data regression with random effects and logistic regression ...

Nanolignin Functional Separators for Flexible Lithium–Sulfur Batteries With Enhanced Performance

open access: yesENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 3, May 2026.
Nanolignin‐functionalized separators, incorporating lignin nanoparticles into a crosslinked PEGDA coating applied on commercial separators, reduce polysulfide shuttling, thereby enhancing cycling performance in flexible lithium–sulfur pouch cells, while also improving thermo‐oxidative stability and flame retardancy.
