Summary: The pyrolysis characteristics of Spirulina platensis, Tetradesmus obliquus, and Chlorella vulgaris were investigated by various techniques. The elemental and biochemical composition of different microalgae influenced their pyrolysis behavior. The pyrolysis process of the three microalgae could be divided into several stages, and the major reaction occurred at a certain temperature range. Different products and activation energies were observed for each microalgae. The pyrolysis of Spirulina platensis produced more CO2 and compounds containing C=O bonds, while Tetradesmus obliquus and Chlorella vulgaris produced slightly higher levels of hydrocarbons.

Summary: This study combines experimental and theoretical calculations to reveal the pyrolysis reaction mechanism and product formation pathway of cellulose. It was found that glucose and cellobiose have two distinct mass loss peaks in their pyrolysis processes, while cellulose has only one. During severe weight loss, cellulose produces more H2O, CO2, alkanes, and carbonyl compounds compared to glucose and cellobiose. Density functional theory (DFT) calculations were performed using beta-D-glucopyranose as a model compound to study the formation mechanism of furan derivatives and carbohydrate derivatives. The relationship between functional groups and the pyrolysis behavior of beta-D-glucopyranose was clarified by combining experimental product distribution and DFT calculations.

Summary: The study investigated the co-pyrolysis of pineapple rind (PR) and low density polyethylene (LDPE) to understand its kinetic, interaction mechanisms, and product characteristics. The co-pyrolysis exhibited synergistic and antagonistic effects at different temperature ranges. The activation energy for co-pyrolysis was lower than that of individual PR or LDPE. The addition of 50% LDPE resulted in the lowest activation energy requirement. The co-pyrolysis inhibited the production of CO2 and promoted the formation of CH4, leading to improved pyrolytic oil quality. Multi-objective optimization suggested the optimal operational conditions for co-pyrolysis of 50% LDPE and 50% PR. This study provided valuable insights for optimizing the co-pyrolysis of fruit residues and plastic polymers.

Summary: This study investigates the pyrolysis performances and reaction kinetics of pine needles using thermogravimetric analysis, Fourier transform infrared spectroscopy, and pyrolysis-gas chromatography/mass spectrometry. It was found that pine needles showed higher pyrolysis efficiency at lower heating rates, while increased heating rates promoted the reaction. The activation energies of hemicellulose, cellulose, and lignin were calculated to be 156, 165, and 172 kJ/mol, respectively, using the King-Kai method. The main pyrolytic by-products identified were hydrocarbons, phenols, alcohols, ketones, and aldehydes. This study demonstrates the significant potential of pine needles as a suitable source for bioenergy.

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.
