Sustainable bio-based film based on chitosan resin crosslinking with tannin, phytic acid and octadecylamine for food packaging application.

Chitosan and tannin are both promising renewable materials for food packaging; however, their effectiveness is limited by incomplete interactions between them. Therefore, phytic acid and octadecylamine were employed to create chitosan-tannin-phytic acid-octadecylamine (CTPO) films that are flame-retardant, UV-resistant, antibacterial and hydrophobic for food packaging applications. The findings indicate that the CTPO film exhibited excellent hydrophobicity and mechanical properties, with a water contact angle of 133.

Ferromagnetic Surface Segregation via Stress-Concentration Coupling Boosts the Oxygen Evolution Reaction in RuO.

RuO, the benchmark catalyst for the oxygen evolution reaction (OER), has traditionally been considered Pauli paramagnetic; however, recent findings have demonstrated its antiferromagnetic (AFM) properties, hinting at the opportunity to enhance RuO's OER performance by manipulating its magnetic traits. In this study, we successfully induced weak ferromagnetism in commercial RuO, transitioning it from an AFM state using an electrochemical sodiation method. This process resulted in high activity, achieving an overpotential of 145 mV to reach 10 mA cm and extending the service hours by more than 13 times compared to pristine RuO in 0.

Deep Learning Based Multiomics Model for Risk Stratification of Postoperative Distant Metastasis in Colorectal Cancer.

Rationale And Objectives: To develop deep learning-based multiomics models for predicting postoperative distant metastasis (DM) and evaluating survival prognosis in colorectal cancer (CRC) patients.

Materials And Methods: This retrospective study included 521 CRC patients who underwent curative surgery at two centers. Preoperative CT and postoperative hematoxylin-eosin (HE) stained slides were collected.

Multiscale non-covalent assembly of proteins and polysaccharides from mechanisms to functional enhancements and applications: A review.

In the context of the escalating global emphasis on healthy food and sustainable development, non-covalent assembly systems formed between proteins and polysaccharides have garnered substantial attention. As natural biomolecules, proteins and polysaccharides synergize to form multiscale complexes through mechanisms such as electrostatic interactions, hydrophobic interactions, and hydrogen bonding, thus exhibiting enhanced stability and functionality. This review identifies five major research hotspots in this field using bibliometric analysis, covering complex formation mechanisms, performance enhancement strategies, and application-expansion directions.

Visible-Light-Induced Organic-Dye-Catalyzed Bromination of Activated Alkenes with Sodium Bromide.

The direct introduction of a bromine atom into organic molecules is valuable because of its versatility in synthetic intermediates and modular building blocks but traditionally suffers from poor selectivity and relatively complicated and/or harsh reaction conditions. We herein present the first visible-light-driven organic-dye-catalyzed bromination protocol under mild conditions with high regioselectivity. This methodology leverages rapid intramolecular radical trapping to achieve regioselective monobromination of alkenes, thus effectively suppressing competing dibromination and electrophilic bromination pathways.
