Improved Performance of Brutian Pine Wood via Impregnation with Nanoclay

open access: yesBioResources, 2023
This study aimed to evaluate the effects of brutian pine (Pinus brutia Ten.) wood impregnation with nanoclay in different concentrations on the chemical and thermal changes, and their impact on the physical and mechanical properties.

The Hydrophilicity of Samama Wood Surface Quality after Boron, Methyl Methacrylate Impregnation, and Heat Treatment

open access: yesJurnal Sylva Lestari
Indicators of surface roughness and surface-free energy can represent the improvement in wood surface quality. In this study, those two indicators were used to determine the change in the samama (Anthocephalus macrophyllus) wood surface following two ...

Ultrafast Vertical Organic Electrochemical Transistors With Ion‐Permeable Conductive Polymer Top Electrodes

open access: yesAdvanced Materials, EarlyView.
Vertical organic electrochemical transistors (vOECTs) are limited in speed by ion‐impermeable metal electrodes that slow ion injection. Using ion‐permeable PBFDO top electrodes allows direct vertical ion injection into BBL channels, achieving high current densities (>400 A cm−2), large on/off ratios (>106), and ultrafast switching in 28 µs. This sets a

Modification of domestic timbers by impregnation using supercritical carbon dioxide

open access: yes, 2022
S.111-116Domestic timbers are often not suited for construction trade applications because of low dimensional stability, low durability or low mechanical strength and are squeezed out of the market by tropical lumbers or other materials (such as plastics

Superconducting coils impregnated with Wood's metal

open access: yesCryogenics, 1975
This report describes the stability of superconducting coils wound with fine multi-filamentary wires and impregnated with Wood's metal.The training effect and current degradation observed before impregnation are remarkably improved after impregnation. The instability of superconductin coils seems to originate in “wire movement” in the winding.

Tg as an index of conversion in PMDI-impregnated wood

open access: yesBioResources, 2007
It is well established that the glass transition temperature (Tg) is a sensitive measure of cure in neat thermosets. As cure advances, network mobility declines and the Tg rises in a systematic fashion. This study sought to determine if such a relationship exists for polymeric isocyanate adhesives (pMDI) cured in the presence of wood.
