A Natural Lignification Inspired Super-Hard Wood-Based Composites with Extreme Resilience. [PDF]

Adv Mater
Super‐hard wood‐based composites (WBC) are designed and developed inspired by the mesoscale homogeneous lignification process intrinsic to tree growth. This innovative hybrid structure is achieved by leveraging the infusion of low‐molecular‐weight phenol formaldehyde resin into the cell walls of thin wood slices, followed by a unique multi‐layer ...

An Upper Bound Visualization of Design Trade‐Offs in Adsorbent Materials for Gas Separations: CO2, N2, CH4, H2, O2, Xe, Kr, and Ar Adsorbents

Advanced Science, Volume 10, Issue 8, March 15, 2023., 2023
This critical review catalogues over 4000 adsorbent materials in a public database for the separation of CO2, N2, CH4, O2, H2 and noble gases. The tradeoffs between capacity, selectivity and heat of adsorption through a bound visualization are described.

Multivariate Image Analysis Applied to Cross‐Laminated Timber: Combined Hyperspectral Near‐Infrared and X‐ray Computed Tomography

Journal of Spectroscopy, Volume 2023, Issue 1, 2023., 2023
Engineered wood products, such as cross‐laminated timber (CLT), are becoming more popular in the designs of modern sustainable buildings. This increased production of CLT requires more robust, yet less labour‐intensive means to assess the material characteristics of whole CLT panels.

Acidic wood extractives accelerate the curing process of emulsion polymer isocyanate adhesives

Journal of Applied Polymer Science, Volume 139, Issue 21, June 5, 2022., 2022
We systematically investigated the interactions between emulsion polymer isocyanate (EPI) adhesive and extracts of seven wood species using different analytical techniques, especially an Fourier‐transform infrared‐rheometer combination. Significant interactions between the adhesive and extracts of chestnut and oak wood, as well as the selected ...

Fabrication of fire‐response functional separators with microcapsule fire extinguishing agent for lithium‐ion battery safety

Nano Select, Volume 3, Issue 5, Page 947-955, May 2022., 2022
A new type of fire‐response separators is prepared by loading the microcapsule fire extinguishing agent on the surface of the separator. The shell of the microcapsule will break automatically and release the fire extinguishing agent when thermal runaway of LiBs occurs, which can quickly absorb heat through endothermic reaction and ensure LiBs will not ...

Tannin‐based bio‐adhesives for the wood panel industry as sustainable alternatives to petrochemical resins

Journal of Industrial Ecology, Volume 26, Issue 2, Page 627-642, April 2022., 2022
Abstract The development of natural‐based adhesives is a key aspect in reducing the consumption of fossil resources, in adapting to legislation on the use of formaldehyde and in ensuring the sustainability of the wood panel industry. This study focuses on five alternatives for tannin‐based adhesives (tannin‐paraformaldehyde, tannin‐glyoxal, tannin ...

Engineering Wood Products from Eucalyptus spp.

Advances in Materials Science and Engineering, Volume 2022, Issue 1, 2022., 2022
Forest covers 4.06 billion hectares (ha) or 31% of the total land area worldwide, where 93% (3.75 billion ha) are natural regenerating forests and the remaining 7% (294 million ha) are planted forests. Eucalyptus spp., being one of the most important plantation species, has been planted in 95 countries around the world, and the area of plantation has ...

In Polymerization of Environment Friendly Melamine‐Urea‐Glyoxal Resin in Rubber Wood for Improved Physical and Mechanical Properties

International Journal of Polymer Science, Volume 2021, Issue 1, 2021., 2021
In the study, we report that a safe and simple way for upgrading inferior rubber wood through the combined modification of environment‐friendly MUG resin was synthesized from glyoxal, melamine, urea, and other additives. MUG‐treated wood samples were prepared with six different MUG resin concentrations (5, 15, 25, 35, 45, and 55 wt %) into the wood ...

The Study of the Adhesive Activity and Modification Possibilities of Melamine-Urea-Formaldehyde (MUF), Urea-Formaldehyde (UF) Resins

Material Science and Applied Chemistry, 2014
Two types of thermosetting resins MUF and UF have been used as glues for birch wood veneer. As resins modifiers polyvinylacetate emulsion (PVA), polyvinylbutiral (PVB) (powder and solution), rubber latex, adipic (Ad) and sebacic (Seb) acids have been utilized.

Melamine Sponge Functionalized with Urea-Formaldehyde Co-Oligomers as a Sorbent for the Solid-Phase Extraction of Hydrophobic Analytes

Molecules, 2018
A new procedure for the functionalization of melamine sponge (MeS) with urea-formaldehyde (UF) co-oligomers is put forward. The procedure differs from the typical synthesis of the UF co-polymer, as it employs a base-catalyzed condensation step at certain
