The development of a formaldehyde-free soy flour adhesive with good coating ability, mildew resistance, and flame retardancy while maintaining high bond strength, is urgent but presents a challenge. Inspired by the strong adhesive performance derived from the brush-like structure of gecko toes, a...

The components of poplar mechanical pulp (PMP), including cellulose, hemicellulose, and lignin, were regulated through a drop-down synthesis method to prepare a series of mechanically superior raw, hemicellulose-containing (HNP), lignin-containing (LNP), and pure cellulose nanopaper (CNP). The...

The unreported 3′-(3,3-dimethylbicyclo[2.2.1]hept-2-ylidene)-5′-phenyl-isoxazoline was synthesized by cycloaddition reaction of 2-(3,3-dimethylbicyclo[2.2.1] heptan-2-ylidene) acetaldehyde oxime (camphene aldoxime, CAO) and syrene. The structure of the product was identified by FT-IR, GC-MS, ¹H NMR ...

The study presents the preparation of novel biocomposites based on different lignin fractions and polylactic acid (PLA). Based on the improvement of PLA mechanical properties, we proposed a process to assemble a series of lignin samples and PLA matrix using melt blending to investigate the effects...

The office staff often sit in poor designed office chairs for long periods, which could cause serious health problems. Adding an ergonomic consideration for designing office chairs can drastically enhance human body posture, leading to the reduction of back pains and improvement of office working...

Soy protein-based adhesives show great prospects in replacing aldehydes resin adhesives to fabricate wood-based panels, however, high doses of synthetic resins as crosslinkers must be used to obtain good bonding performance. To reduce overreliance upon crosslinkers derived from fossil resources, a...

Human health and environmental protection demand wood-based panel industry for innovative soy-based adhesives with high production efficiency, straightforward synthesis processes, non-toxicity, and high bonding performance. A simple and efficient microwave pretreatment process and low addition of...

Synthetic fibres such as polyester and carbon are used in a broad variety of industries. However, as they derive from petrochemicals that are neither renewable nor biodegradable, the development of natural alternatives has gained increasing momentum in recent years. Here, we report a top-down...

Wood is complex in its chemical composition that has an important influence on its chemical behavior and mechanical strength. The complexity is reflected in the ultrastructure of the wood cell wall. In particular, the concentration of main components (cellulose, hemicelluloses and lignin) changes...

Objective: This study aims to investigate the chemical composition, cell wall ultrastructure and supramolecular structure of cellulose in balsa wood fibers, as well as reveal their influence on mechanical properties of balsa wood and demonstrate the relationship between ultrastructure and...
