Mechanistic Insights Into Sustainable Catalytic Pyrolysis of Biomass‐Derived Ferulic Acid: The Role of Alumina Regeneration

open access: yesChemistry – A European Journal, EarlyView.
Surface‐bound ferulate phenolate complexes undergo styrene‐like polymerization on alumina, yielding a polymeric carbonaceous layer that progressively transforms into polyaromatic carbon domains with concomitant release of aromatic products, while parallel surface‐assisted decarboxylation produces 4‐vinylguaiacol. ABSTRACT A fundamental understanding of

CEO Overconfidence and Corporate Social Responsibility: A Micro‐CSR Perspective

open access: yesCorporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT Although research on micro‐level CSR has increasingly emphasized individual‐level antecedents, the role of CEO overconfidence has not been systematically integrated into the literature. To address this gap, a systematic literature review was undertaken of 62 studies on CEO overconfidence and CSR, revealing a mixed picture of positive, negative,

Maximising trait evenness promotes the recovery of plant species richness in managed grasslands

open access: yesEcography, EarlyView.
Land‐use intensification threatens biodiversity, and restoring degraded ecosystems remains challenging due to the difficulty of identifying the rules governing community assembly and dynamics. Investigating the temporal dynamics of trait‐abundance distributions (TADs) along long‐term time series offers a promising approach to disentangle the influence ...

Caracterização de compostos reduzidos de enxofre gerados na produção de celulose kraft e pré-hidró lise kraft

open access: yesCiência Florestal, 2002
An environmental concern in the kraft pulping is the odor caused by the reduced sulphur compounds.There are many simple equipments to detect on-line the total reduced sulphur (TRS), like the coulometric titrator.

Catalyst-Free Depolymerization of Methanol-Fractionated Kraft Lignin to Aromatic Monomers in Supercritical Methanol

open access: yesEnergies
Lignin is considered a renewable source for the production of valuable aromatic chemicals and liquid fuel. Solvent depolymerization of lignin is a fruitful strategy for the valorization of lignin.

Faster growing and more functionally diverse: global change alters functional trait composition of mountain plant communities in the European Alps

open access: yesEcography, EarlyView.
Understanding how global change reshapes mountain plant communities is essential for predicting biodiversity and ecosystem function in a warming world. Using resurvey data from over 1400 non‐forest vegetation plots across the European Alps, we show that community‐weighted means of key functional traits capturing important dimensions of plant ecological

FAULT TOLERANT CONTROL APPLICATION FOR CONTINUOUS KRAFT PULPING PROCESS

open access: yesIFAC Proceedings Volumes, 2006
Abstract In this study, the fault tolerant Kappa number control in continuous cooking application is investigated. The Kappa number is one of the quality measures in the pulp cooking process and usually the only on-line measurement. It is a measure of the residual lignin content in the pulp.

Lignocellulosic Triboelectric Materials for Energy Harvesting and Emerging Applications: A Review on Lignin‐Molecular Engineering toward Improved Performance

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Contrasting sustainable biomass with depleting petroleum resources, this review charts the evolutionary timeline of lignin‐based TENGs. We systematically evaluate their fundamental mechanisms, enhancement strategies, and applications in green self‐powered electronics.
