Summary: Bleaching of recycled newsprint fibers involves optimizing variables such as hydrogen peroxide charge, sodium hydroxide amount, pulp consistency, bleaching temperature, and bleaching time. Higher hydrogen peroxide charge improves brightness, while sodium hydroxide prevents brightness reversion and increases fiber flexibility. Higher pulp consistency is favorable, and optimal temperature and time conditions are crucial for bleaching effectiveness. Multiple pre-washings can enhance brightness and save bleaching chemicals.

Summary: The study on the influence of nanofibrillated cellulose (NFC) as a reinforcing agent for recycled paper sheets showed that the addition of NFC can significantly improve the mechanical properties of the papers, but a high addition may lead to increased water retention, which is undesirable for papermaking. With optimum selection of NFC/NFC-OX and process conditions, higher mechanical properties could be acquired without increasing drainage rate.

Summary: The goal of this study was to recycle waste paper as filler and investigate the properties of the obtained recycled polypropylene-based composite. Crystalline cellulose from waste paper was regenerated using an acid medium method under mild conditions. The extracted cellulose particles had more amorphous regions and a more hydrophilic structure compared to kraft pulp. These cellulose microparticles were used as a biofiller in the recycled polypropylene-based composite, with an adhesion enhancer improving its mechanical properties, hydrophobicity, and thermal stability.

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.
