pH-responsive κ-carrageenan/HPMC biodegradable films incorporated with roselle anthocyanin for freshness indication Introduction Biodegradable HPMC/κ-carrageenan-based intelligent films incorporating berry-derived anthocyanins have been reported; however, the effect of anthocyanin source on polymer compatibility and functional performance remains underexplored. Roselle ( Hibiscus sabdariffa L. ) anthocyanins, rich in delphinidin- and cyanidin-based derivatives with high acidity and antioxidant capacity, may enhance pH responsiveness and bioactivity in polymer matrices. Methods HPMC/κ-carrageenan films containing 0–2% (w/w) roselle anthocyanin (RA) were prepared using solvent casting. Films were evaluated for mechanical properties, water solubility, swelling index, antioxidant activity, thermal stability (TGA), polymer–anthocyanin interactions (FTIR), biodegradation (soil burial), and color-response behavior during storage of button mushrooms at 25 °C. Results Film thickness ranged from 0.047 to 0.076 mm. Increasing RA content significantly reduced tensile strength (43.5 to 11.5 MPa) and elongation at break (18.2% to 6.06%), while decreasing water solubility and swelling index, thereby improving moisture barrier performance. Antioxidant capacity increased with RA concentration, reaching 80.63% DPPH radical scavenging at 2% RA. FTIR confirmed polymer–anthocyanin interactions, and TGA showed maintained thermal stability. Soil burial tests indicated substantial biodegradation within 21 days. Films applied to button mushrooms exhibited a color change from red to black within 32–36 hours, indicating spoilage. Discussion The incorporation of roselle anthocyanin into HPMC/κ-carrageenan films improved antioxidant and moisture barrier properties while providing a clear pH-sensitive color response.

Visible-light Emission and Guidance in Adenine Crystals Luminescence in biomolecules remains a vibrant frontier captivating researchers worldwide, yet nucleobases like adenine linger as underexplored gems. In this study, we unveiled adenine's outstanding emissive potential: protonation triggers green fluorescence (≈ 500 nm) in solution, while its crystals show intense blue emission (412 nm) with high quantum yield (66%) under 365 nm ultraviolet irradiation. Corroborated by crystallographic analysis and controlled experiments, a decent understanding of underlying mechanisms is proposed. Furthermore, the potential optical waveguiding capabilities of adenine crystals were investigated, revealing excellent performance.

Quantum Dot Sensitized Solar Cells (QDSSCs): Materials, Performance, and Prospects Quantum Dot Sensitized Solar Cells (QDSSCs) represent an advanced class of third-generation photovoltaic devices that utilize the quantum confinement effects of semiconductor nanocrystals for enhanced light harvesting. This study explores CdSe, InP, and CuInS₂-based QDSSCs synthesized via SILAR and hot-injection techniques, emphasizing tunable bandgaps, multiple exciton generation (MEG), and surface passivation for improved performance. UV–V is spectra revealed bandgaps between 1.5–2.5 eV, dependent on particle size. Under AM 1.5G illumination, CdSe-based devices achieved 5.0% power conversion efficiency (PCE), outperforming InP (3.3%) and CuInS₂ (2.7%) devices. Electrochemical impedance spectroscopy confirmed that CdSe exhibited the lowest charge-transfer resistance and highest electron lifetime. A case study using Delhi’s July 2025 solar irradiance data demonstrated 21.6% efficiency for a 3 kW system and an average output of 17.21 kWh/day for a 10 kW installation. These findings indicate that while CdSe QDs deliver higher efficiency, eco-friendly alternatives such as InP and CuInS₂ offer sustainable solutions. Integrating solid-state electrolytes, core–shell architectures, and scalable deposition methods can drive QDSSCs toward commercialization in flexible, wearable, and building-integrated photovoltaic.

Advances in Polymer Micelles for Cancer Therapy: From Conventional to Smart Delivery Systems Polymeric micelles have become a versatile and clinically significant class of nanocarriers for cancer therapy. They effectively solubilize poorly water-soluble anticancer drugs, extend their circulation in the bloodstream, and promote accumulation in tumors. Early studies focused on conventional PEG-based polymeric micelles that utilize passive targeting based on the enhanced permeability and retention (EPR) effect, with several of these advancing to clinical trials. Active targeting strategies using modified polymer micelles with various targeting ligands have been introduced to enhance cellular uptake and improve tumor specificity. Recently, the field has shifted toward smart polymer micelles that can respond to both internal (endogenous) and external (exogenous) stimuli. These stimuli-responsive systems enable controlled drug release, enhance delivery inside cells, and improve therapeutic effectiveness, all while reducing systemic toxicity. This review summarizes recent advancements in polymer design, drug-loading techniques, preparation methods, and targeting strategies for polymeric micelles, highlighting both preclinical progress and systems that have reached clinical stages. The transition from conventional to smart polymer micelles is a significant advancement toward achieving more precise, effective, and personalized cancer nanomedicine.

Enhanced THz Emission and Exciton Transfer in Monolayer MoS <sub>2</sub> /GaAs Heterostructures For designing an efficient terahertz (THz) emitter, the defect density of the semiconductors is smartly increased to reduce carrier lifetime, which subsequently lowers the overall power output of the semiconductor. To overcome this fundamental trade‐off, this study presents a novel approach by integrating a direct bandgap 2D semiconductor, such as monolayer MoS 2 (1L‐MoS 2 ) with a well‐known THz emitter and low‐temperature‐grown gallium arsenide (GaAs). The fabricated hybrid 2D/3D vertical van der Waals heterostructure shows a 15% higher THz emission compared to bare GaAs due to phase‐coherent addition of second‐order nonlinear susceptibility, and overall enhancement in the electric field of the laser. The photoluminescence (PL) enhancement factor of 2.38 in heterostructures at GaAs emission energy of 1.42 eV. However, the substantial quenching of PL emission for 1L‐MoS 2 at the energy of 1.84 eV is attributed to the Dexter‐type exciton transfer mechanism at type‐I band alignment. THz time‐domain spectroscopy reveals a significant increase in optoelectronic properties, such as optical conductivity becoming doubled, and a 50% reduction in absorption coefficients. The study introduces a new route for fabricating large‐area and compact mixed‐dimensional van der Waals heterostructures, which can be used to enhance the efficiency of conventional semiconductor technologies and THz‐based optoelectronic devices.

Jellyfish-derived bioplastics: properties, degradation, and marine applications In this review, the potentials of jellyfish-based plastics as an alternative to conventional plastics are looked at principally regarding their use at sea. The collagen and additional biopolymers extracted from jellyfish have distinct physical and chemical properties i.e., biodegradability, toughness, and can blend with the environment, which enables it to manufacture green material to substitute the plastic fillers found in the ocean. In the review, what is known about jellyfish biomolecules is summarized, their properties studied, and how these biomolecules are subjected to biodegradation in marine ecosystems, as well as their use to package, create fishing gear, marine sensors, and agrochemical release controls in aquaculture, is discussed. The effect of environmental factors on the degradation, useful life cycle and large-scale production and regulation challenges are also examined. This review applies the concepts of material science, marine biotechnology, and environmental policies to suggest significant research gaps, as well as describe potential new concepts that can support the application of jellyfish-derived bioplastics to create marine and environmental sustainability.

In Vitro anticandidal efficiency of newly synthesized zinc oxide/chitosan/vancomycin nanocomposite using Bacillus Licheniformis compared to fluconazole The zinc oxide/chitosan nanocomposite functionalized with vancomycin (ZnO/CS/VA), which acts as a novel anticandidal modifier, was prepared using an environmentally friendly technique. Zinc oxide nanoparticles (ZnO NPs) were biosynthesized using Bacillus licheniformis ATCC 4527 and then linked to chitosan (CS) and vancomycin (VA) through a green chemical method. Several methods were utilized to characterize the prepared nanocomposite. UV-Vis spectroscopy results indicated an absorption peak at 348 nm. Fourier transform infrared spectroscopy (FTIR) and X-ray diffractometer (XRD) analyses demonstrated that the material matrix of the nanocomposite included ZnO NPs and various active groups. Transmission electron microscopy (TEM) images showed that the ZnO/CS/VA nanocomposite was spherical-shaped with a size range of 56-80 nm. The anticandidal effect of ZnO/CS/VA, used as a modifier to enhance antimicrobial activity, was tested against Candida albicans ATCC 10231. ZnO/CS/VA exhibited significant anticandidal activity in the agar well-diffusion test, minimum inhibitory concentration (MIC), and minimum fungicidal concentration (MFC) compared to the standard drug fluconazole. As the ZnO/CS/VA dose and the anticandidal inhibition increased, the antimicrobial activity became reliant on the nanocomposite dose. Five μg/mL was enough to cause complete biocidal action against Candida albicans, while 25 μg/mL of fluconazole was required. TEM micrographs of ZnO/CS/VA-treated Candida albicans showed various malformations and distortions in cell structure, including damage to the cell wall and the presence of vacuoles, indicating its potent antimicrobial effects. The results suggest that the combination of zinc oxide/chitosan nanocomposite and vancomycin could serve as an effective biomaterial for antifungal treatment and other medical applications.

Development of Transparent Glass Coating Using Methyltrimethoxysilane (MTMS) and Tungsten Oxide (WO3) for UV Light-Blocking Applications Ultraviolet (UV) radiation poses significant risks to human health and interior materials, creating a demand for effective transparent shielding solutions. While organic polymer-based filters are widely used, they often suffer from poor weatherability and mechanical instability. This study aims to develop a durable, transparent, and hydrophobic UV-shielding coating using a methyltrimethoxysilane (MTMS) matrix reinforced with tungsten oxide (WO3) nanoparticles, specifically designed for scalable retrofitting on glass substrates. Nanocomposite coatings were prepared by dispersing WO3 nanoparticles into MTMS/ethanol solution. Four formulations were synthesized with WO3 loadings of 0, 6.25, 12.5, and 25 wt% relative to the precursor. The coatings were applied to glass slides using a facile sponge-coating technique. Characterization included Field Emission Scanning Electron Microscopy (FESEM) for morphology, X-ray Diffraction (XRD) for crystallinity and Fourier-Transform Infrared (FTIR) spectroscopy for chemical bonding. Optical performance was evaluated via ultraviolet-visible (UV-Vis) spectroscopy (200–900 nm) and surface wettability was assessed using water contact angle measurements. Mechanical durability was tested using the standard pencil hardness test before and after 48 hours of water immersion. XRD and FTIR analyses confirmed the successful covalent anchoring of crystalline WO3 nanoparticles into the siloxane network. FESEM revealed a crack-free surface with homogeneous nanoparticle dispersion. A direct trade-off between UV-shielding and visible transparency was quantified. The 25 wt% sample achieved the highest UV-shielding (81.08%) but suffered from low visible transparency (TVis = 50.44%). The 6.25 wt% formulation was identified as optimal, delivering 63.23% UV-shielding while maintaining high transparency (TVis = 76.32%), surpassing the architectural standard of 70%. All coatings maintained 9H pencil hardness even after water immersion, though hydrophobicity decreased slightly with higher WO3 loading due to surface hydroxyl groups. The MTMS-WO3 coatings demonstrate an excellent balance of optical clarity, UV protection and mechanical hardness compared to conventional soft-polymer films. The 6.25 wt% formulation is proposed as the optimal concentration for durable and transparent UV-shielding applications in architectural and automotive glazing.

Ginger peel waste cellulose, mimosa cinerea fiber: light weight application with sustainable PLA composites Mimosa cinerea natural fiber (NFR), ginger waste filler (WF) was incorporated into a Poly(lactic acid) (PLA) matrix to enhance tensile strength (TS), reduce thickness swelling (TSW) property in a corrosive state. The X-ray diffraction (XRD) of WF revealed a 110 plane at 15.8° and a 200 plane at 22.6°, the Fourier-transform infrared spectroscopy (FTIR) identified peaks at 1085 cm− 1 and 1520 cm− 1, confirming high cellulose content in treated WF. In the compression moulded PLA composites, TS increased from 47.55 to 55.71 MPa as NFR content rose from 15 to 25 wt% with a constant 5 wt% WF. Improved hydrogen bonding among hydroxyl groups in NFR and WF contributed to this enhancement. The better combination of NFR (25 wt%), WF (5 wt%), NaOH Surface treatment (ST) (9 wt%), fiber length (LF) (1 cm), and 190 °C, attained TS of 58.4 MPa, 22.1% higher than neat PLA matrix. The WF addition reduced voids between NFR and PLA, lowering TSW in corrosive environments. Surface treatment up to 9 wt% produced a cellulose-rich, rough surface that improved PLA-NFR interaction, enhancing compatibility and increasing both TSW and TS. The better results were identified with NFR (15 wt%), WF (5 wt%), ST (3 wt%), LF (3 cm), and 190 °C for minimizing TSW in the hybrid PLA composite with 0.3% under corrosive conditions.

Construction of N/S CQDs@Fe-TCPP Nanocatalyst-Induced Electrochemical Sensors for Rapid and Sensitive Detection of Enrofloxacin Residues in Milk Given the potential hazards of enrofloxacin (ENR) residues to human health, establishing an accurate, rapid, and stable detection method is of importance. To enable the direct detection of ENR, an electrochemical sensor was constructed in this study. N- and S-doped carbon quantum dots (CQDs) with peroxidase-like activity were prepared using DL-malic acid, L-alanine, and L-cysteine as precursors and compounded with a tetrakis (4-carboxyphenyl) porphyrin (TCPP) and Fe(NO<sub>3</sub>)<sub>3</sub>·9H<sub>2</sub>O to make novel N/S CQDs@Fe-TCPP composite carbon-based nanozymes to construct an electrochemical sensor, and the electrochemical behavior was investigated. Under optimal experimental conditions, the sensor exhibited a linear current response to ENR concentrations in the range of 1-1300 nM (I (μA) = 0.0106c (nM) + 2.9861, R<sup>2</sup> = 0.9962), with a calculated detection limit of 0.872 nM (S/N = 3). The recovery rate of this sensor in actual milk samples ranged from 99.02% to 100.9%. The reproducibility experiments demonstrated the high precision of the method, with a relative standard deviation (RSD) of 1.27%. Stability testing revealed a peak current retention rate of 93.51% on day 21, indicating excellent system stability. These findings indicate that the sensor shows great capability for ENR detection in food products.
