A study of the importance of secondary reactions in char formation and pyrolysis : a dissertation presented in partial fulfilment of the requirements for the degree of Doctor of Philosophy in Process Engineering at Massey University, Manawatū, New Zealand [PDF]

open access: yes, 2016
Anthropogenic climate change, caused primarily by excessive emissions of carbon dioxide, has led to a renewed interest in char, the solid product of pyrolysis. When applied to soil as biochar it can both sequester carbon and improve soil function.

Effects of Heat Treatment on Durability of Merbau Heartwood

open access: yesBioResources, 2015
Merbau wood has been widely used in outdoor applications. However, it has a disadvantage in that its water-soluble extractives readily leach out and stain adjacent materials. Heat treatment is an efficient technique to solve this problem.

Artefacts Associated With Cryogenic Vacuum Distillation Do Not Compromise Plant Source Water Extraction From Soil and Xylem for Isotope Analysis

open access: yesEcohydrology, Volume 19, Issue 3, April/May 2026.
ABSTRACT Understanding the oxygen and hydrogen isotopic composition (δ18O and δ2H values, respectively) of plant source water is fundamental for tracing water uptake in ecohydrological studies. However, discrepancies between cryogenic vacuum distillation (CVD)‐extracted soil and xylem water and known plant source water δ18O and δ2H values continue to ...

Radial Distribution of Lipophilic Extractives in Walikukun (Schoutenia ovata Korth.) Wood

open access: yesSouth-East European Forestry
Walikukun (Schoutenia ovata Korth.) is a commercially significant wood species in Indonesia. Heartwood, in particular, is important due to the natural durability and aesthetics, while lipophilic extractives play a crucial role in the formation. Therefore,

Using Radon (222Rn) to Trace Variability in Greenhouse Gas Emission From Tree Stems Across Species, Seasons and Stem Heights

open access: yesEcohydrology, Volume 19, Issue 3, April/May 2026.
ABSTRACT Emissions from trees are an important component of the global methane (CH4) cycle, but their spatial origins (soil vs. in‐stem), transport pathways and environmental influences are not well constrained. To address these issues, this field study characterized spatial and temporal variability in stem emissions of biologically inert radon (222Rn),

Effect Of Planting Spacing In Production And Permeability Of Heartwood And Sapwood Of Eucalyptus Wood

open access: yesFloresta e Ambiente, 2019
The objective of this work was to evaluate the influence of different useful areas provided by the planting spacings (3 × 1, 3 × 2, 3 × 3, 3 × 4 m) on the production and permeability of heartwood and sapwood of Eucalyptus grandis and Eucalyptus grandis ×
