Influence of thermal modification on nail withdrawal strength of spruce wood

BioResources, 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

LOSS OF STRENGTH IN BIOLOGICALLY DEGRADED THERMALLY MODIFIED WOOD

BioResources, 2012
The durability of thermally modified (TM) and untreated (UT) mini-stakes exposed to in-ground contact was compared by modulus of elasticity (MOE) and mass loss with decay type using microscopy. Results showed a strong correlation between MOE and soft rot decay for UT stakes over a 30 month exposure period. For TM stakes, the correlation between MOE and

Properties of Thermally Modified Woods by a Brazilian Process

The 3rd International Electronic Conference on Forests—Exploring New Discoveries and New Directions in Forests, 2022
Thermal modification processes are strategies used to improve the properties of wood with an environmental liability when no chemicals are used. The Vap HolzSysteme®, developed in Brazil, promotes a thermal modification in wood when using an atmosphere saturated with water vapor thus ensuring a low oxygen content in the pressure system.

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

Floresta 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

Journal 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.

Microstructure of thermally modified radiata pine wood [PDF]

BioResources, 2020
The thermal modification of wood is a potential alternative method for improving wood dimensional stability and increasing the resistance of wood to decay. However, during thermal modification, morphological changes occur within the microstructure of the cell, and these confer different properties to the wood. This study investigated the effects of the

Current Status and Challenges in Data Collection for Aerospace Coatings Deposited by Plasma Spraying

Advanced Engineering Materials, EarlyView.
An innovative approach has been integrated into the GRENAT project to optimize plasma spraying and coating performance. Raw materials are accelerated and melted in the plasma generated by torches, creating coatings. Monitoring sensors collect process data which are combined with ex situ characterization data.

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

BioResources, 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

Electrochemical Behavior of Flame‐Sprayed Sc‐Doped AlCoCrFeMo High‐Entropy Alloy Coatings in 3.5% Sodium Chloride Solution

Advanced Engineering Materials, EarlyView.
Scandium (Sc)‐doped AlCoCrFeMo HEA coatings are fabricated via flame spraying with 0.1, 0.3, and 0.5 wt% Sc additions. Among these, the HEA‐Sc0.3 coating exhibits the highest corrosion resistance, indicated by a more positive corrosion potential and lower current density.
