Precipitation of Lignin from Softwood Black Liquor: An Investigation of the Equilibrium and Molecular Properties of Lignin

open access: yesBioResources, 2015
Extracting lignin from black liquor is an attractive option in modern pulp mills as a unit process for a combined biorefinery. The lignin obtained can be utilized as solid fuel or other high-value added products.

Estimation of Error Margin in the Quantification of Large Wood Volumes in River From In Situ and UAV Measurements

open access: yesEarth Surface Processes and Landforms, Volume 51, Issue 10, October 2026.
Large wood (LW) plays a key role in river dynamics and biodiversity, but quantifying its volume and budget remains challenging. This study compared in situ and UAV‐based measurements of LW jams in two Gaspé Peninsula rivers (Québec, Canada), highlighting strong variability mainly due to operator bias. A new methodology reduced this variability, leading

The importance of biodiversity components differs among wood‐based material Nature's contributions to people (NCP) in a tropical montane ecosystem

open access: yesOikos, Volume 2026, Issue 10, October 2026.
Biodiversity can influence forest productivity, but this does not necessarily translate into higher provision of wood‐based Nature's contributions to people (NCP), as only a subset of the wood produced is used for each NCP. Biodiversity–NCP relationships therefore require further assessment.

Almond Shell‐Derived Cellulosic Microfibres: Extraction, Characterisation and Applications in Sustainable Paper‐Based Packaging

open access: yesPackaging Technology and Science, Volume 39, Issue 10, Page 1231-1251, October 2026.
Cellulosic microfibres were extracted from almond shells using organosolv, soda and kraft processes, and comprehensive physicochemical, surface, thermal and morphological characterisation demonstrated their strong potential as sustainable fillers for paper‐based packaging application. ABSTRACT This study develops pathways for the valorisation of almond

Thermal behaviour of hardwood and softwood composites

open access: yes, 2014
In the present study, the thermongravimetric analysis (TGA) of laboratory hardwood and softwood particleboard was studied. The TGA showed that both hardwood and softwood have similar thermal behaviour at the same peak temperature.

Colonial Cartography and World Heritage Valuing in Takayna Country: A Reflection on the Use of the Simple Additive Weighted Method

open access: yesAustral Ecology, Volume 51, Issue 10, October 2026.
ABSTRACT In many regions there are disputes about future land use that make knowledge of spatial variation in conservation value an important input to negotiation. Current approaches to measuring spatial conservation values for the purposes of recognition and protection remain largely trapped in colonising cartographic methodologies that marginalise ...

The Unexpected Discovery of Paleocene? Coals in Outcrops Thought to Be Cambrian, Al Huqf, Oman

open access: yesJournal of Petroleum Geology, Volume 49, Issue 4, Page 1179-1194, October 2026.
ABSTRACT Two brown organic deposits were encountered whilst investigating kaolinitic claystones thought to occur at the base of a Cambrian formation at outcrop. The age of these organic deposits is probably Paleocene from palynology. Organic petrography shows that they are subbituminous coals with some oil source potential.
