A broader application of biocomposites still faces many challenges regarding structural integrity, environmental resistance, and biodegradability. These issues are particularly important when their marine applications considered. Therefore, this paper seeks to address the hygroscopicity, mechanical properties, biofouling resistance made epoxy resin with 28 m% bio-based carbon content reinforced...

Hemp nut is commonly incorporated into several food preparations; however, most countries set regulations for hemp products according to their cannabinoid content. In this study, we have developed an efficient microwave-assisted extraction (MAE) method for cannabinoids (i.e., Δ9-tetrahydrocannabinol, cannabidiol, and cannabinol) in hemp nut. Optimization of the MAE procedure was conducted throu...

Cannabis sativa L. (Cannabaceae) is one of the earliest known cultivated plants and is important in the global economy today as a licit and an illicit crop. Molecular markers distinguishing licit and illicit cultivars have forensic utility, but no direct comparison of hemp and marijuana amplified fragment length polymorphism (AFLP) has been made to date. Genetic variation was surveyed in three ...

In this study, dyeing of two regenerated polyester fibers, poly-trimethylene terephthalate (PTT) and poly-lactic acid (PLA), with natural dyes were compared with that of poly-ethylene terephthalate (PET) fiber. Lac was used as the primary natural colorant while Catechu was chosen as a natural color that can also act as a biomordant. The effects of temperature, initial pH of dye bath and dyeing ...

Efficient liberation of fermentable soluble sugars from lignocellulosic biomass waste not only decreases solid waste handling but also produces value-added biofuels and biobased products. Industrial hemp, a special economic crop, is cultivated for its high-quality fibers and high-value seed oil, but its hollow stalk cords (hurds) are a cellulosic waste. The cellulose-solvent-based lignocellulos...

The development of many engineered product applications for automobiles and aircraft parts has initiated the search novel materials as alternatives to metal matrix composites (MMCs). Natural-fiber-reinforced polymer offer distinct advantages such biodegradability, eco-friendliness, flexibility, low density, higher specific strengths, etc. This study focuses on natural-fiber (hemp banana)-fabric...

Hemp concrete is more and more recommended by eco-builders because hemp is a renewable plant, recyclable and does not degrade within time. To integrate this material into buildings, it is important to study its hygrothermal behaviour. In this paper, two models have been investigated: a heat transfer model (Th) and a hygrothermal model accounting for heat and moisture transport through building ...
