Green preparation of highly transparent nano-NH-UiO(Zr)-66/cellulose composite films with high-strength, superior flame retardant and UV to high-energy blue light shielding performance.

Int J Biol Macromol

January 2025

Engineering Research Center for Hemp and Product in Cold Region of Ministry of Education, School of Light Industry and Textile, Qiqihar University, Qiqihar 161006, PR China. Electronic address:

From the perspective of sustainable development and practical applications, there is a significant demand for the design of advanced cellulose-based film materials with superior mechanical, optical, and functional properties utilizing environmentally friendly strategies. Herein, biodegradable, mechanically robust and flame-retardant cellulose films with adjustable optical performance were successfully fabricated by in situ synthesis of NH-UiO(Zr)-66 via a DMF-free green process at room temperature. The results indicate that the introduction of NH-UiO(Zr)-66 enables films to realize a desirable flame retardancy (the limiting oxygen index (LOI) increased significantly from 19.

Plastics play an essential role in modern fisheries and their degradation releases micro- and nano-sized plastic particles which further causes ecological and human health hazards through various environmental contamination pathways and toxicity mechanisms, which can cause respiratory problems, cancer, reproductive toxicity, endocrine disruption and neurological effects in humans. This study utilized various bioinformatics tools through multi-step computational analyses to investigate the interactions between prevalent fisheries microplastics and the key protein receptor acetylcholinesterase (AChE), which is associated with neurotoxicity, as it can interfere with nerve impulses and muscle control. Our results indicate that the binding of seven polymers within AChE's active site, with dodecane and polypropylene exhibited highest affinity with hydrogen bonding were observed through Molecular docking of different program (PyRx) and servers (CB-Dock, eDock) then the stability of AChE-dodecane and AChE-polypropylene complexes were observed through MD simulations for 100 ns.

The Effectiveness of Polyhydroxyalkanoate (PHA) Extraction Methods in Gram-Negative U.

Polymers (Basel)

January 2025

Área de Bioquímica y Biología Molecular, Departamento de Biología Molecular, Universidad de León, 24007 León, Spain.

Bioplastics are emerging as a promising solution to reduce pollution caused by petroleum-based plastics. Among them, polyhydroxyalkanoates (PHAs) stand out as viable biotechnological alternatives, though their commercialization is limited by expensive downstream processes. Traditional PHA extraction methods often involve toxic solvents and high energy consumption, underscoring the need for more sustainable approaches.

In this study, we aimed to explore the feasibility of utilizing polypropylene (PP) and natural rubber (NR) blends as alternative materials for rubber dam clamps in dentistry. The hardness of various PP/NR blend ratios was compared to the commercial product SoftClamp. Selected blend ratios exhibiting hardness values resembling rigid plastic were further evaluated for hardness and tensile strength after undergoing 1, 5, and 10 autoclave cycles.

Pre- and Post-Procedural Considerations and Thread Types for Thread Lifting.

Life (Basel)

January 2025

Division in Anatomy and Developmental Biology, Department of Oral Biology, Human Identification Research Institute, BK21 FOUR Project, Yonsei University College of Dentistry, 50-1 Yonsei-ro, Seodaemun-gu, Seoul 03722, Republic of Korea.

Facial thread lifting has emerged as a minimally invasive alternative to traditional face-lifting procedures, with particular emphasis on U-shaped and I-shaped barbed threads. This review analyzes the anatomical considerations, procedural techniques, and clinical outcomes of different thread types for facial rejuvenation. The study examines the mechanical principles and lifting mechanisms of U-shaped "suspension type" threads versus I-shaped threads, highlighting their distinct characteristics and applications.
