Summary: This study synthesized bacterial cellulose/gum Arabic composite (BC/GA) through in-situ modification using lavender residue hydrolysate for the first time. Adding gum Arabic during in-situ modification significantly increased the yield and production per sugars consumption of BC/GA. The combination of BC and GA was identified as the main mechanism for the beneficial effect of in-situ modification.

Summary: This study confirmed the effect of the protein expansin on the structure of cellulose microfibrils, showing that expansin can disrupt hydrogen bonding between cellulose microfibrils without causing massive disintegration of the cellulose structure. This ultimately mild modulation of cellulose microfibril structure highlights the physiological importance of expansin in the remodeling of plant cell walls.

Summary: Graphitic carbon nitride (CN) coupled with microcrystalline cellulose (MCC) (MCC-X/CN) exhibits excellent photocatalytic performance for tetracycline (TC) degradation and H-2 evolution. The optimized MCC-0.05/CN shows significantly improved TC degradation rate and H-2 evolution rate compared to pure CN. This improvement is primarily attributed to the hydrogen bonding (H-bonding) between CN and MCC, enabling excellent charge separation and migration.

Summary: In situ modification of bacterial cellulose (BC) by adding agar and chitosan to the culture media leads to structural and morphological tuning, affecting water absorption/retention and rheological behavior. Agar-modified BC shows reduced pore volume and denser network with lower water absorption, while Chitosan-BC exhibits lower pore volume and reduced swellability with lower water retention. The viscoelastic deformation mechanism and water absorption behavior are discussed with respect to pore shape-size distribution and fiber dimension.

Summary: 3,5-Dihydroxyphenyl-5-(dimethylamino)naphthalene-1-sulfonate (sensor R1) forms hydrogen bonding connections in its crystal structure, but no pi-pi stacking interactions between molecules were observed. Addition of fluoride ion resulted in a new absorption band and quenched the emission peak of sensor R1. Other anions also showed a slight decrease in corresponding peaks in the UV-visible and emission spectra of sensor R1. The complex formed between sensor R1 and fluoride ion has a 1:1 stoichiometry and a Stern-Volmer quenching constant of 7157 M-1.

Summary: Molecular dynamics simulations were used to investigate the pseudo-recrystallization of dislocated cellulose regions in CMFs, suggesting that 3-4 glucose residues bordering each side of a cellulose nanocrystal are reorganizing. The estimated length of the dislocated cellulose segments in CMFs for cotton and ramie sources ranges from 3.1-5.8 nm, equivalent to 6-11 glucose residues in the cellulose crystallites.

Summary: A new strategy for in situ modification of water-insoluble modifiers was proposed in this study. Experimental results showed that xanthan gum as a suspending agent can uniformly and stably disperse water-insoluble plant extracts in the culture medium to prepare the in situ modified bacterial cellulose (BC) products. The in situ modified BC products exhibited reduced crystallinity, significantly increased swelling ratio, and strong antibacterial and antifungal activities. This study has important implications for the biopolymer industry.

Summary: Bacterial cellulose (BC), a natural biopolymer produced by bacterial fermentation, has unique physical and chemical properties. The single functional group on the surface of BC limits its wider application, thus functionalization of BC is crucial. In this study, N-acetylated bacterial cellulose (ABC) was successfully prepared using a direct synthetic method. The modified BC showed lower crystallinity and higher fiber width compared to pristine BC. Cell viability tests and hemolysis ratios indicated the biocompatibility of ABC. Furthermore, the acetyl amine modified BC was further treated by nitrifying bacteria to expand its functional diversity. This research provides an environmentally friendly pathway for the construction of BC derivatives during its metabolism.

Summary: In this study, a Ru/CeO2 Mott-Schottky electrocatalyst with a built-in electric field (BEF) was designed to ensure the consumption rate of noble metals and guarantee satisfactory hydrogen evolution reaction (HER) performance at different pH values. Both theoretical calculations and experimental analysis confirmed that the improved HER activity in the Ru/CeO2 catalyst could be attributed to the successful construction of BEF at the interface between the Ru clusters and CeO2. The Ru/CeO2 catalyst achieved high current densities at low overpotentials in alkaline, acidic, and neutral media, and also demonstrated good power generation stability in alkaline-acidic Zn-H2O cell applications.

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.
