Biological Reviews, EarlyView.ABSTRACT The ecology of forests, their losses, and terrestrial wood decomposition dynamics have been intensively studied and reviewed. In the aquatic realm, reviews have concentrated on large wood (LW) in rivers and the transition from freshwater to marine environments in the Pacific Northwest of North America. However, a comprehensive global synthesis

Effect of Physical Properties of Softwoods on Embedment Strength Performance of Self-tapping Screws
BioResources, 2023 The embedment strength performance of the self-tapping screw (STS) connector, used as a cross-laminated timber fastener, was evaluated considering tree species’ density and load direction as parameters.

Carbon Energy, EarlyView.The low light/CO2 capture and slow dynamic transfer of photogenerated electrons hamper photocatalysts’ high activity and selectivity. Inspired by the chloroplast's photosynthesis mechanism, an all‐in‐one lignin‐based artificial thylakoid nanovesicle (AiO‐L‐ATN) is constructed using a confined growth strategy of lignin molecules. The performance of such

Revisiting acidulation for tall oil and lignin manufacturing
The Canadian Journal of Chemical Engineering, EarlyView.Abstract Tall oil is a byproduct of the kraft pulping process when softwood is used as raw material. As the production of softwood‐based pulp is in high demand, the optimization of the tall oil production process needs to be revisited to ensure the highest quality and quantity of tall oil manufacturing. In this work, the process for tall oil production

The Canadian Journal of Chemical Engineering, EarlyView.Abstract Magnetic biochar (MBC) is a novel bio‐metallic composite material with high potential in sustainable water cleaning. Iron anchoring is critical in forming iron‐based MBC and will fundamentally impact its characteristics and functionality in dye removal applications. However, the mechanism is not well‐revealed.

A review of the configuration of bordered pits to stimulate the fluid flow
Maderas: Ciencia y Tecnología, 2014 As the bordered pits have generally been thought to have an influence on the refractory nature of softwoods, structural behaviour of this conducting pathways is discussed according to the published literature.
