This study explores the Triki-Biswas (TB) model, a novel model describing soliton dynamics in monomodal optical fibers with non-Kerr dispersion, to obtain optical solitons. Optical bright and singular solitons were derived using the generalized Jacobi elliptic function (gJEF) method and the [Formula: see text]expansion method. Trigonometric, hyperbolic, exponential, polynomial, and rational functions are obtained. The physical dynamics of the obtained solutions confirmed the existence of known complex structures, such as shock waves, dark solitons, periodic waves, and singular periodic solutions. The simulations generated in Mathematica 11.3 are graphically presented to depict the nature of the acquired solutions. These results are novel and have not been reported previously in the literature.

Poly(3-hexylthiophene) (P3HT)-based complex topological copolymers have attracted a great deal of attention for their unique electrical and optical properties. In this contribution, the P3HT-based Janus fibers with controlled lengths were innovatively prepared by sequential crystallization-driven self-assembly (CDSA) of poly(--butylstyrene)--polyisoprene--poly(3-hexylthiophene) (PBS--PI--P3HT) triblock copolymer, cross-linking of the interlayer PI region, and dissociation of fibers in good solvent. The comprehensive characterizations showed that the PBS/P3HT Janus fibers have nearly half the width of PBS--PI--P3HT fibers and fiber lengths close to or slightly shorter than those of PBS--PI--P3HT fibers, indicating that the Janus fibers with adjustable lengths could be prepared in a large window range.

Incorporating atomically thin two-dimensional (2D) materials with optical fibers expands their potential for optoelectronic applications. Recent advancements in chemical vapor deposition have enabled the batch production of these hybrid fibers, paving the way for practical implementation. However, their functionality remains constrained by the integration of a single 2D material, restricting their versatile performance.

The development of sensors for monitoring breath acetone, a key biomarker for ketosis in diabetes mellitus, represents a critical frontier in medical diagnostics, promising a painless alternative to invasive blood tests. This review provides a comprehensive and critical evaluation of the state-of-the-art in acetone gas sensing technologies, including chemiresistive, optical, electrochemical, conductometric, and microwave platforms. We focus specifically on recent breakthroughs driven by advanced materials, analyzing how novel nanostructures from two-dimensional (2D) materials such as MXenes to porous metal-organic frameworks (MOFs) are engineered to push performance to clinically relevant parts-per-billion (ppb) sensitivity.

The persistent presence of Metronidazole (MTZ), a commonly used antibiotic, in water bodies is a serious environmental and health concern because of its genotoxic and carcinogenic potential. Here, we report an effective visible-light photocatalyst system comprising an S-scheme glycine-modified TiO/FeO heterojunction immobilized on chitosan-polyacrylonitrile nanofibers. The photocatalyst nanocomposite was synthesized through a sol-gel and ultrasonication process coupled with electrospinning-assisted immobilization.
