Summary: This study demonstrates that cellulose nanocrystals and nanofibers isolated from agro-waste can be used as reinforcements in a thermoplastic starch matrix to obtain environmentally friendly materials that can substitute contaminant polymers. The addition of nanocrystals and nanofibers improves the mechanical and antibacterial properties, as well as the solubility and water vapor permeability of the biocomposites. The study offers new insights into the improvement of starch films using different proportions of nanofibers and nanocrystals.

Summary: Sweet potato starch and different celluloses were mixed and used to prepare thermoplastic starch/cellulose composite films. The effect of different celluloses on the properties of the films were studied. It was found that sugarcane cellulose had better compatibility with sweet potato starch, resulting in improved mechanical properties. Cornstalk cellulose had the highest thermal degradation temperature, while rice bran cellulose had the largest elongation at break. Bamboo or cornstalk cellulose films had lower water vapor permeability, while rice bran cellulose had higher permeability. The findings provide a theoretical basis for improving the properties of thermoplastic starch films.

Summary: The use of polymers in thin films or substrates contributes to environmental issues, and therefore, biodegradable materials should be used instead. To address this problem, sustainable fillers and reinforcements are needed to replace synthetic materials. However, incorporating Tin oxide (SnO) in nanofibril cellulose reinforced thermoplastic starch (NCF/TPS) can result in lower mechanical properties and higher water absorption. This study prepared SnO/NCF/TPS nanocomposites with different SnO contents (0, 1, 2, 3, 4, and 5 wt.%) using stir casting methods, and characterized them in terms of dimensional stability and tensile properties. The results showed that the highest SnO content led to the lowest density, water absorption, and thickness swelling properties, and the incorporation of 4 wt.% SnO resulted in better tensile properties compared to other formulations.

Summary: The research found partial compatibility of cassava starch and corn starch with polycaprolactone (PCL) in the blends, along with changes in crystal quality of PCL and displacement of absorption bands in the infrared spectrum. The crystallinity of PCL in the presence of cassava and corn starch was higher than that of pure PCL, suggesting improved nucleation at the interface. Based on these findings, the blends are suitable for manufacturing short-term use products using conventional thermoplastic processing methods.

Summary: The effect of pH on the extraction yield of phenolic compounds from liquid phases recovered after the hydrothermal treatment of black liquor was studied using batch and continuous reactors. It was found that reducing the pH slightly improved the extraction of phenol and guaiacol, but greatly increased the extraction yield of syringol. Lower pH also hindered the hydrolysis of ethyl acetate during liquid-liquid extraction. The experiments confirmed the superior performance of the continuous reactor and the degradation of phenolic products at higher treatment temperatures.

Summary: This study successfully fabricated plywood boards using virgin and recycled high-density polyethylene (vHDPE and rHDPE) films as formaldehyde-free adhesives, and achieved improved physical and mechanical properties by using PE-g-MA as a coupling agent. PE-g-MA played a crucial role in enhancing the interfacial bonding ability and stress propagation. The properties of plywood boards made with rHDPE were significantly improved, although the presence of impurities in the recycled film made the coupling agent less effective.

Summary: The present study aimed to minimize or eliminate the harmful effects of urea-formaldehyde (UF) resin by using recycled high-density polyethylene (HDPE) as a nontoxic adhesive. The results showed that HDPE films provided mechanical properties comparable to UF adhesive, even with lower adhesive content and pressing time. The optimum conditions were an HDPE loading of 240 g/m(2), a hot-pressing temperature of 160°C, and a hot-pressing time of 5 min. This study confirmed the potential of recycled HDPE as a promising adhesive for environmentally-friendly plywood manufacturing.

Summary: Liver disease is a major cause of global mortality, and identifying biomarkers for diagnosing its progression is crucial for improving outcomes. Targeted mass spectrometry is a powerful tool for verifying biomarker candidates and clinical applications, particularly for glycoproteins translation. However, the limitation of analyzing only one sample per run has become apparent. In this study, a high-throughput intact N-glycopeptides quantification strategy was developed, allowing the validation of 20 samples per run with an average analysis time of 3 minutes per sample. The strategy was applied in a cohort of 461 serum samples and identified a panel of 10 IgG N-glycopeptides that have strong clinical utility in evaluating the severity of liver disease.
