Influence of Zwitterionic Buffer Effects with Thermal Modification Treatments of Wood on Symbiotic Protists in Reticulitermes grassei Clément [PDF]

open access: yesInsects, 2021
The majority of thermal modification processes are at temperatures greater than 180 °C, resulting in a product with some properties enhanced and some diminished (e.g., mechanical properties).

Modification of the surface of thermally modified wood with ozone when creating glued structures [PDF]

open access: yesE3S Web of Conferences, 2021
The greatest interest of researchers is focused on the processes of heat treatment of wood, taking place in an airless environment at temperatures of 180-250 °C, since heat treatment of wood allows increasing its moisture resistance, reduce ...

New Composite Materials Based on Chitosan Films Reinforced with Chitin Nanofibrils for Cosmetic Application

open access: yesCosmetics, 2023
Bioactive biodegradable chitosan films containing chitin nanofibrils have been developed for use as face masks in cosmetology. It was found that thermal modification of chitosan films promotes the transformation of the polymer into insoluble form without

Triazolinedione-'clicked' poly(phosphoester)s : systematic adjustment of thermal properties [PDF]

open access: yes, 2017
The thermal properties of halogen-free flame retardant poly(phosphoester)s from acyclic diene metathesis polycondensation have been optimized by a systematic post-modification using 1,2,4-triazoline- 3,5-dione derivatives.

The Influence of Different Wood Modifications on Pull-out Force of Rotary Welded Dowels

open access: yesDrvna Industrija, 2023
The increasing use of modified wood justifies the intention to use it in joints made by rotary welding with dowels. Thermal modification, for example, increases the dimensional stability of wood by reducing its hygroscopicity and water absorption, but it

Influence of silicone oil thermal modification on mechanical properties of masson pine wood

open access: yesMaderas: Ciencia y Tecnología, 2021
In this study, the effect of silicone oil thermal modification at different treatment temperatures (150 ºC, 180 ºC and 210 ºC for 2 h and 4 h.) on the mechanical properties of masson pine (Pinus massoniana L.) wood was investigated. The density, modulus
