An fNIRS Study of the Effects of Sound in Real Scenes on Joint Attention among Individuals With Autistic Traits in China.

There is no consensus on whether adult with autistic traits joint attention (JA) deficits. Additionally, previous studies have mostly been conducted in traditional laboratory settings, lacking ecological validity. This study aimed to address these limitations by using real-life scenarios and functional near-infrared spectroscopy (fNIRS) techniques to investigate the impact of sound cues on JA among individuals with Autistic Traits in China.

Self-healing, flame retardant and UV resistant lignin-derived epoxy wood coating with a Schiff base structure.

The traditional epoxy resin not only is flammable and non-recyclable and but also heavily dependents on petroleum resources, which cannot meet the requirements of fire prevention and sustainable development. In this study, a vanillin intermediate (VAP) with dynamic imine bond (C=N) was prepared by schiff base reaction between the lignin derivative vanillin (-CHO) and the cage-like polyhedral oligomeric silsesquioxane OA-POSS(-NH). Then, a biomass-based P-N-Si flame retardant (VAPD) was synthesized by adding 9,10-Dihydro-9-Oxa-10-Phosphaphenanthrene-10-Oxide (DOPO) into the VAP.

Toxic Gas and Smoke Generation and Flammability of Flame-Retardant Plywood.

Limited by flammability, wood and wood-based materials face challenges in distinguishing themselves as structural materials or finishing materials. Once burning, they can produce toxic gases detrimental to humans and the environment. Therefore, it is critical to make clear whether fire-retardant wood construction materials are insusceptible to fire and not the sources of toxic gases.

Preparation of Organic-Inorganic Phosphorus-Nitrogen-Based Flame Retardants and Their Application to Plywood.

The combustibility of wood can be improved by physical and chemical means, thus expanding the use of wood products. In this study, two novel phosphorus-nitrogen flame retardants (UCPR and MCPR) were developed, and the intercalated modified layered double hydroxides (LDH) thereof were designated as UCPR-LDH and MCPR-LDH. By impregnating poplar veneer with UCPR-LDH and MCPR-LDH solutions, the study investigated the effects of different concentrations (1%, 5%, 10%), processes (vacuum-pressure impregnation, room temperature impregnation, normal-pressure impregnation), and impregnation times (2 h, 3 h, 24 h, 48 h) on the weight-gain rate of veneer.

Research Progress on the Improvement of Flame Retardancy, Hydrophobicity, and Antibacterial Properties of Wood Surfaces.

Wood-based materials are multifunctional green and environmentally friendly natural construction materials, and are widely used in decorative building materials. For this reason, a lot of research has been carried out to develop new and innovative wood surface improvements and make wood more appealing through features such as fire-retardancy, hydrophobicity, and antibacterial properties. To improve the performance of wood, more and more attention is being paid to the functioning of the surface.

Research and Application of Biomass-Based Wood Flame Retardants: A Review.

Wood is widely used as a construction material due to its many advantages, such as good mechanical properties, low production costs, and renewability. However, its flammability limits its use in construction. To solve the problem of wood flammability, the most common method to improve the fire safety of wood is to modify the wood by deep impregnation or surface coating with flame retardants.
