Summary: This study presents an experimental investigation on the acoustic absorption of fabric acoustic panels with non-woven fabric cores and fabric facings made of date palm midribs-fibers. The results showed that the 50 mm-thick midribs-fibers cores exhibited the highest absorption, while the 150 kg/m3 cores achieved a balance between high tortuosity and porosity. The tests on full assemblies demonstrated that the panels with woven midribs-fibers facings of 30 mm-150 kg/m3 and 40 mm-100 kg/m3 cores had significantly high absorption at low and high frequencies, and the panels with cotton facings of 40 mm-100 kg/m3 and 50 mm-200 kg/m3 cores showed competitive overall performances to commercial acoustic panels.

Summary: Researchers and industry are searching for green and sustainable materials for lightweight composites. This study focused on investigating the characteristics of fibre extracted from date palm spathe waste. The results showed that the fibre had a density of 0.59 g/cm3, a crystallinity index of 57.82%, a crystal size of 19 nm, a degradation temperature of 270°C, and an Ea of 69.14 kJ/mol. Scanning electron microscopy confirmed the presence of surface contaminants. Based on the findings, SDP fibres should be considered as a reinforcing material for lightweight industrial applications.

Summary: Expenditure isolation of lignin and the understanding of its structural variations during different isolation processes are crucial for the high-value utilization of lignin. This study proposed a green deep eutectic solvent (DES) consisting of choline chloride, ethylene glycol, and 4-chlorobenzene sulfonic acid for rapid lignin separation from poplar. The structural variations of DES lignin and its relationship with alkali pre-extraction of hemicellulose were investigated. The results showed that alkali pretreatment enhanced the DES separation of lignin and promoted the cleavage of specific linkages, resulting in reduced molecular weight and thermal stability of isolated DES lignin. Moreover, DES lignin obtained from integrated utilization displayed higher purity and S/G ratio compared to lignin obtained from direct DES treatment.
