Summary: The study focused on preparing a biocomposite material with a superhydrophobic surface by reinforcing waste polypropylene with sisal fibers. The optimal fiber content was determined to be 15% based on characterization results. Surface modification was carried out to enhance hydrophobicity, leading to self-cleaning and low wet ability properties.

Summary: Biosorption is a technique used to treat heavy metal-contaminated soils by using biological materials to accumulate contaminants. This study investigated the bioavailability of Cd2+ and Pb2+ in an Alfisol after applying sisal residues and correlated the adsorption of these ions with the characteristics of the residues. The application of sisal residues in the soil reduced the available levels of Cd2+ and Pb2+ by up to 40%, regardless of the dosage, and increased the dry mass of Sorghum bicolor plants. The residues also alleviated phytotoxicity caused by Pb2+ contamination. Cd2+ showed a strong correlation with lignocellulosic parameters, while Pb2+ showed a lower correlation.

Summary: The study revealed temporal and spatial distribution patterns of arthropods and plants in a sisal crop, with July showing the highest biodiversity. Specific plant species were found to be important for certain arthropods. Arthropods seemed to colonize the sisal crop from surrounding fields during the rainy season.

Summary: Biomass estimation is crucial for crop monitoring and carbon cycling assessments. This study successfully used Sentinel-2 multispectral satellite imagery to model leaf biomass of sisal, demonstrating the suitability of multispectral data for assessing biomass at plantation and block levels. The study also highlights the importance of spectral vegetation indices for biomass estimation.

Summary: The study aimed to extract a polyphenol-enriched extract from sisal residue using ultrasound, characterize it chemically, evaluate its antioxidant activity, and develop safe and stable photoprotective formulations for cosmetic applications. The extraction process showed promising results in terms of yield and antioxidant properties, and the developed formulations incorporating the extract demonstrated increased sun protection factor and protection against UVA and visible/blue light.

Summary: In this study, a needled nonwoven (NNW) composed of polyphenylene sulfide fibers and pre-oxidized fibers was used as a substrate to incorporate silica aerogel (SiAG/NNW) for thermal insulation. The SiAG/NNW showed high temperature resistance and excellent thermal insulation, with the ability to withstand butane flame for 4 minutes at about 1300 degrees C. The SiAG/NNW also exhibited higher weight loss temperature and improved carbon residue rate compared to individual NNW or SiAG.

Summary: This study investigated the acid hydrolysis extract from sisal juice and found that it has a powerful anti-inflammatory effect. It can be considered as a potential new anti-inflammatory drug or a source of steroidal glucocorticoids. However, further studies are needed to determine the chemical composition of sisal juice. Furthermore, the extract showed strong reproductive toxicity in rats.

Summary: This work focuses on the characterization and comparative study of agave americana and agave sisalana leaf fibers as potential alternatives to synthetic fibers in engineering applications. The physical-chemical and mechanical properties of the fibers were determined using various analytical procedures and instruments. The results indicate that both agave fibers possess unique features that make them desirable as reinforcement fibers for composite engineering, with different compositions and microstructures.

Summary: This paper investigates the use of geotextiles as insulation materials for energy geostructures made of compacted soil. Results show that the thermal conductivity of geotextiles varies depending on the material type and compression stress. The importance of compression load and moisture environment in using geotextiles as insulation products is highlighted.
