Photo-triggered and magnetically guided nanosystems for precision drug transport: architecture development, spectral analysis and release behavior Enhancing therapeutic selectivity while minimizing the collateral damage associated with conventional chemotherapeutic agents remains a persistent challenge in cancer treatment. To address these limitations, we developed a multifunctional drug delivery platform that combines magnetic guidance with light-triggered release, enabling precise spatial and temporal control over drug availability. The nanocarrier was constructed from superparamagnetic Fe 3 O 4 nanoparticles, which serve as the magnetic core, allowing external field–assisted localization at the desired site. This magnetic core was further encapsulated by a mesoporous silica shell composed of highly ordered channels, providing a large accessible volume for efficient drug loading and enhanced structural stability during circulation. To introduce external responsiveness, a photo-switchable organic ligand (2-bromo-Benzophenone hydrazone) was covalently anchored onto the internal pore surfaces of the silica framework. Under controlled light irradiation, this ligand undergoes reversible conformational changes that modulate the accessibility of the mesopores, enabling the pores to function as controllable “valves.” As a result, drug molecules can be selectively released at a higher rate when triggered by optical stimulation. Comprehensive physicochemical characterization, including SEM, TEM, XRD, FT-IR spectroscopy, thermogravimetric analysis, and nitrogen adsorption–desorption isotherms, confirmed the successful construction of the core–shell architecture and the effective incorporation of the light-responsive gating system. Biocompatibility was assessed using SMMC-7721 cell lines, and the results indicated minimal cytotoxicity from the carrier itself, demonstrating its suitability for biomedical applications. In vitro release experiments further showed that the nanocomposite exhibits magnetically assisted positioning and a tuneable release profile governed by light exposure. These findings suggest that this dual-responsive platform offers a promising strategy for programmable, site-specific drug delivery with the potential to significantly reduce off-target toxicity and improve therapeutic precision.

Enhancing Stability at High Temperature in GaSb‐Based Phase‐Change Materials via Carbon Introduction Phase‐change materials are key candidates for next‐generation nonvolatile memories, yet their reliability at elevated temperatures remains challenging. In this work, we investigate the effects of carbon introduction on GaSb‐based alloys to enhance thermal stability and data retention while minimizing mechanical stress. Systematic in situ X‐ray diffraction, sheet resistance, and X‐ray reflectivity analyses reveal that carbon incorporation significantly modifies the crystallization kinetics and structural evolution. At high C contents, the crystallization temperature increases by over 40°C (up to about 282°C), and the activation energy rises, indicating improved data retention. Simultaneously, carbon decreases Sb phase segregation, reduces grain sizes, and induces a compressive strain in the GaSb lattice, consistent with CSb bonds formation that limits atomic diffusion. Forwards‐backward sheet resistance measurements as a function of temperature confirm that the amorphous phase remains stable up to ∼270°C, nearly 90°C higher than in reference alloy without C. The resulting C‐incorporated GaSb exhibits a tenfold higher electrical contrast and an extrapolated 10 year stability of the as‐deposited amorphous phase at 187°C. With reduced density change upon crystallization (&lt;4%), carbon introduction effectively enhances both phase and mechanical stability, making GaSb‐C alloys promising candidates for high‐temperature, high‐endurance embedded phase‐change memory applications.

The Effect of Cellulose Fibers Recovered from Primary Sludge on Concrete Performance The construction industry faces urgent pressure to adopt sustainable, low-carbon materials. Fiber reinforced concrete appears as a more sustainable alternative to conventional concrete due to its improved mechanical properties and durability. Commonly tested synthetic fibers do not provide holistic economic and environmental benefits. Wastewater treatment plants (WWTP) are emerging as resource recovery hubs for biopolymers like cellulose, offering an eco-friendly alternative to synthetic fibers. However, the application of sewage-derived cellulose fibers in cementitious composites remains under-explored. This study evaluates the integration of cellulose fibers, extracted from primary sludge of a WWTP as an alternative to synthetic fibers in concrete applications. We incorporated recovered cellulose fibers at a 0.2% w/w into concrete (0.5% v/v) and evaluated the fresh and hardened properties of this fiber reinforced concrete. While fiber addition reduced workability due to high water absorption, it significantly improved mechanical performance. Compressive strength increased by 5% at 7 days and 6% at 28 days. These improvements are attributed to internal curing effects and enhanced fiber-matrix bonding. This research demonstrated a viable pathway for upcycling sewage-derived cellulose into sustainable construction materials within a circular economy framework.

Production and Characterization of Cellulose and Cellulose Nanocrystals From Moss Syntrichia ruralis (Hedw.) F. Weber &amp; D. Mohr. Cellulose is the most abundant and widespread polymer in nature; it attracts the attention of many researchers as it can replace edible, ready-to-use and developable polymeric materials. However, perennial trees are generally preferred for cellulose production, which causes the destruction of forests and the disruption of the natural balance. The present study aimed to isolate Syntrichia ruralis cellulose to develop a new alternative source for cellulose production. Acid hydrolysis was applied to obtain cellulose nanocrystals (CN). The morphology, topology, crystallinity and thermal properties of the cellulose and CN obtained in this study were investigated in detail. Hemicellulose and lignin were almost completely removed from cellulose produced by alkali and bleaching processes, as shown by Fourier transform infrared spectroscopy (FTIR). The significant effects of zeta potential on dispersion stability were investigated using atomic force microscopy (AFM) to determine the resulting roughness. Thermal and mechanical properties of TGA were investigated. In addition, the morphology of CN films was investigated by SEM measurements. As a result, Syntrichia ruralis has been shown to be an alternative source of nanocellulose with the potential for use in many fields.

Chemical characterization, antioxidant, cytotoxicity, and anti-human breast cancer potentials of <i>Allium ampeloprasum</i> green-formulated silver nanoparticles by investigating the p53 and cell cycle G1, S, G2, and M phases In this study, we used the leaves of Allium ampeloprasum to report on biogenic supported silver nanoparticles (AgNPs). The leaves of Allium ampeloprasum were utilized as a green reducing agent and a superior stabilizer for the AgNPs that were synthesized. The as-synthesized AgNPs were physicochemically characterized by Fourier-transform infrared (FT-IR), X-ray diffraction (XRD), field emission-scanning electron microscopy (FE-SEM), transmission electron microscopy (TEM), UV-Vis, and energy dispersive X-ray (EDX). The antioxidant activity of the AgNPs was assessed using the DPPH assay; they showed significant antioxidant activity, as per the IC 50 value. Because of their antioxidant qualities, recent nanoparticles seem to have an anti-human breast carcinoma effect. AgNPs that were biologically produced were evaluated for their anti-breast cancer properties against breast cancer cell lines. According to the MTT assay results, AgNPs’ anti-breast cancer qualities could effectively eradicate the MCF10 cancer cells, depending on both concentration and time. AgNPs induce cell death, followed by downregulation of the anti-apoptotic marker BCL-2 and overexpression of the pro-apoptotic markers BAX and cleaved caspase-8. Furthermore, in contrast to their corresponding control, Ag NPs prevented colony formation. More significantly, the investigation of molecular pathways of cells treated with AgNPs showed that increasing p53 expression. This implies that the extract’s pharmacological effects on human breast cancer cells were mostly caused by p53.

Plausible Response of Poly(ferrocenylmethylphenylsilane) in Solution and Solid State to Fluoride Ions ABSTRACT The development of reliable materials for the detection of fluoride in water is critical due to its widespread occurrence and associated health risks. In this study, we synthesized the previously reported poly(ferrocenylmethylphenylsilane) (PFMPS) and its composites with polystyrene (PS), with a focus on its response to fluoride ions in both solution and solid states. The interaction of PFMPS with fluoride sources ([Bu 4 N]F and NaF) was systematically investigated using UV–vis spectroscopy, nuclear magnetic resonance ( 2 9 Si, 1 9 F NMR), Raman spectroscopy, thermogravimetric analysis (TGA), differential scanning calorimetry (DSC), scanning electron microscopy with energy‐dispersive X‐ray spectroscopy (SEM‐EDS), and atomic force microscopy (AFM). UV–vis analysis revealed a marked decrease in the characteristic absorption bands of PFMPS upon exposure to fluoride, even at low concentrations, indicating a high sensitivity attributed to the interaction with the silicon atom. Raman, AFM, and SEM‐EDS mapping confirmed fluoride incorporation, while NMR analysis further validated structural changes at the silicon center. DSC and TGA results demonstrated increased thermal stability of the fluoride‐treated polymer, with altered thermal transitions and degradation profiles. These findings demonstrate the potential of PFMPS‐based materials as responsive platforms for fluoride detection, offering a promising avenue for the development of organometallic polymer sensors for environmental monitoring.

Industrial Cannabis sativa (fiber or hemp): Retting, Hemp Cellulose Extraction and Composite Thin Films for Food Packaging This literature review paper highlights preparation of hemp cellulose based thin films for the food packaging industries. The Industrial Cannabis sativa L. (Hemp) is a short-season crop with many applications which is used as a functional food, fibre, 3D printed building material hempcrete, biochar, bioplastic, paper, textile, biofuel, oil, cosmetics, skincare, animal bedding, ropes, medicine and as a replacement for graphene in supercapacitors. The hemp stalk has two main fibre types: long outer bast fibers and short inner hurd fibres. The outer bast fibres surround the vascular tissue of the hemp stalk. The main macromolecular compound that occurs in bast fibres is cellulose (40 and 80% of dry mass) used for the preparation of composite films for food packaging industries. The extraction of fibers from harvested hemp stems begins with ‘‘retting’’ for an initial weakening of interactions between the fiber bundles and the woody core and surrounding tissue. Cellulose measured at nanoscale is known as nanocellulose. Nanocellulose are of two types which are cellulose nanocrystals (CNCs) and cellulose nanofibrils (CNFs). Nanocellulose could replace petroleum-based materials due to its promising advantages, including rich sources, biodegradability, excellent mechanical properties, and biocompatibility. Nanocellulose composite films and coatings can extend shelf life and maintain the quality of diverse food products such as fruits, vegetables, and meats, as has already been reported by some relevant studies.

Superparamagnetic Nanoparticles Targeting Brain Cancer: Innovations in Carbohydrate-Based Coatings and Magnetic Field Guidance The effective treatment of aggressive brain tumors, such as glioblastoma, is critically hindered by the blood-brain barrier (BBB) and the non-specific clearance of therapeutic agents by the immune system. Superparamagnetic iron oxide nanoparticles (SPMNPs) offer a powerful theranostic platform, combining magnetic resonance imaging (MRI)-based diagnostics with therapeutic delivery and hyperthermia. However, their clinical translation requires sophisticated strategies to ensure precise delivery to the tumor site. This review examines innovative functionalization strategies to enhance the targeting and efficacy of SPMNPs. Specifically, it addresses the various strategies for coating magnetic nanoparticles with carbohydrates, including both covalent and non-covalent methods, and the subsequent functionalization of these glycoconjugates to exploit the unique biological environment of brain tumors. The use of glycoconjugates on the nanoparticle surface is a key strategy, leveraging the altered glycosylation patterns and overexpression of specific lectins on glioma cell surfaces to achieve highly selective cellular targeting. The review details the synergistic effect achieved by combining these functionalized nanoparticles with external magnetic field guidance. This combination provides a dual-action mechanism: the magnetic field actively guides the nanoparticles across the BBB and concentrates them within the tumor mass, while the carbohydrate coating ensures specific cellular uptake, thereby significantly improving local therapeutic concentration and minimizing systemic toxicity. The scope of this review includes the development and evaluation of carbohydrate-coated SPMNPs, outlining their optimized physicochemical properties for both in vitro and in vivo imaging and treatment of cancerous brain tissues. This comprehensive evaluation represents a critical advancement in biomedicine, aiming to improve the prognosis for patients with brain cancer through more precise and effective therapeutic interventions.

The Influence of Methods for Distributing the IF-WS2 Modifier into the Structure of Al2O3 Aluminium Oxide Coatings on Their Micromechanical Properties This work examines the micromechanical response of Al<sub>2</sub>O<sub>3</sub>/IF-WS<sub>2</sub> (IF-inorganic fullerene-like) composite coatings formed on the EN AW 5251 aluminium alloy by anodic oxidation. The resulting amorphous oxide layer contains a nanopores system that can be filled with IF-WS<sub>2</sub> particles, provided the modifier is properly dispersed. Because commercial IF-WS<sub>2</sub> powders exhibit strong agglomeration, a high-intensity ultrasonic treatment was applied to enhance particle separation before incorporation. The influence of newly established incorporation parameters was assessed using a two-level experimental design. As part of the research, analyses of the microstructure, micromechanical, and sclerometric properties were performed. Cross-sectional SEM observations confirmed the presence of IF-WS<sub>2</sub> within the oxide structure and revealed differences in particle distribution, depending on the incorporation technique used. The results indicate that although microhardness and Young's modulus are largely insensitive to the nanopowder incorporation method, the interaction between the anodising current density and the incorporation technique significantly influences the strain energy components and tribological response of the coatings. These findings suggest that appropriately selected processing parameters can be used to tailor the mechanical and tribological properties of Al<sub>2</sub>O<sub>3</sub>/IF-WS<sub>2</sub> coatings to specific loading conditions and functional requirements, rather than striving for a single, universal, optimal processing configuration.

Strong optical anisotropy in one-dimensional phosphorus wavy tubes Anisotropic materials with intrinsic one-dimensional architectures, where chains or tubes align along a crystallographic axis, exhibit direction-dependent optical responses and serve as ideal building blocks for polarization-sensitive optoelectronics. While progress exists in engineered compounds, discovering elemental crystals with naturally ordered one-dimensional building blocks exhibiting giant optical anisotropy remains challenging. Here, we report the synthesis of a direct-bandgap semiconducting one-dimensional phosphorus single crystal composed of unique wavy polygonal tubes. The monoclinic lattice structure is revealed by single-crystal X-ray diffraction and advanced transmission electron microscopy. The crystal exhibits giant birefringence in the visible and near-infrared regions, stemming from electron localization and anisotropic transitions of the phosphorus 3p orbital along the tube axis. The low-symmetry structure endows remarkable linear and nonlinear optical anisotropies, including orientation-dependent photoluminescence, Raman scattering, and second-harmonic generation. This study establishes a paradigm for designing giant optical anisotropies, opening avenues for on-chip polarization devices and nonlinear photonic circuits.

Modulation of Trichromatic Emission Centers in Organic–Inorganic Hybrids for Optoelectronic Applications Organic-inorganic metal halides (OIMHs) have emerged as highly promising novel multifunctional optoelectronic materials, owing to their easily adjustable properties from a variety of combinations of different components. But it is still difficult and rare to realize highly tunable multicolor luminescence within the same material. In this work, we successfully incorporated three adjustable emission centers in OIMHs to synthesize a novel OIMH (NEA)<sub>2</sub>MnBr<sub>4</sub>, with each emission center capable of emitting one of the primary colors-red, green, and blue. The green and red emissions originate from the tetrahedron and octahedron structures in the Mn-based frame, while the blue can be attributed to the contribution of organic components. Additionally, to achieve comparable emission intensity among the three primary colors, we enhanced the blue emission performance by optimizing the ratio of organic structure components and incorporating chirality in the OIMHs. The resulting high-quality films can be obtained by spin-coating method with a photoluminescence quantum yields of up to 96%. More interestingly, by the dual manipulation of excitation wavelength and temperature, the sample can be emitted at least seven distinct colors including a standard white luminescence at (0.33, 0.33), opening up promising prospects for multicolor luminescence applications such as high-end anti-counterfeiting technology, light-emitting diodes, X-ray imaging, latent fingerprints, humidity detection, and so on. Therefore, based on application scenarios and requirements, our research on this highly tunable luminescent OIMH material lays a solid foundation for further development of various functional properties of related materials.
