Influence of thermal modification on nail withdrawal strength of spruce wood

open access: yesBioResources, 2014
This paper deals with nail withdrawal strength of spruce (Picea abies L.) with a focus on its dependence on thermal modification. Nail withdrawal strength is a feature of wood that is very important in the construction of wooden buildings. There are many

Physical Properties of Thermally Modified Juvenile and Mature Wood of Hevea brasiliensis (Euphorbiaceae)

open access: yesFloresta e Ambiente, 2020
Exposing timber to temperatures approaching 200 °C causes thermal modification and changes its characteristics. This study evaluates the effect of various levels of thermal treatment on the physical properties of juvenile and mature wood from rubber tree

Changes in Chemical Structure of Thermally Modified Spruce Wood Due to Decaying Fungi

open access: yesJournal of Fungi, 2022
Fungi play a critical role in the decomposition of wood and wood-based products in use. The ability of decaying fungi to cause degradation of polysaccharides and lignin in the thermally modified Norway spruce (Picea abies L.

Novel hydrophobization of wood by epoxidized linseed oil. Part 1. Process description and anti-swelling efficiency of the treated wood [PDF]

open access: yes, 2014
The known method of wood modification by epoxidized linseed oil (ELO) has a limiting practical application due to the rapid polymerization of ELO in the presence of acetic acid (AA) needed as a catalyst.

New Natural Injection-Moldable Composite Material from Sunflower Oil Cake [PDF]

open access: yes, 2006
Through a twin-screw extrusion process the native structure of sunflower oil cake was completely transformed (globular protein denaturation/texturization and husk fiber defibration) into a simpler matrix-fiber structure, as could be seen on SEM ...

Thermogravimetric analysis of commercial thermally modified wood

open access: yesDrewno. Prace Naukowe, Doniesienia, Komunikaty = Wood. Research Papers, Reports, Announcements, 2015
In the article the results are shown of a thermogravimetric analysis of four thermally modified wood species. Thermally modified wood before and after the extraction process was used for the tests. The extraction process had no significant effect on changes in the thermal characteristics either in the raw wood or in the modified wood, irrespective of ...

Evaluation of Lauric-Myristic Acid as Phase Change Material in Thermally Modified Wood for Thermal Energy Storage

open access: yesBioResources, 2023
Thermally modified Scots pine samples were impregnated with lauric acid (LA) and myristic acid (MA) as phase change material (PCM) by vacuum process.  The LA-MA mixture was prepared at a eutectic ratio of 66 to 34 wt%. Some properties of the wood samples

Large‐scale bidirectional arrayed genetic screens identify OXR1 and EMC4 as modifiers of αSynuclein aggregation

open access: yesFEBS Open Bio, EarlyView.
Activation of the mitochondrial protein OXR1 increases pSyn129 αSynuclein aggregation by lowering ATP levels and altering mitochondrial membrane potential, particularly in response to MSA‐derived fibrils. In contrast, ablation of the ER protein EMC4 enhances autophagic flux and lysosomal clearance, broadly reducing α‐synuclein aggregates.

Effect of moisture on the bending properties of thermally modified beech and spruce [PDF]

open access: yes, 2018
For appropriate and successful applications of thermally modified wood, a detailed knowledge of its distinct properties is essential. A thermal modification leads to structural and chemical changes in the wood constituents, which may significantly alter ...
