Abstract This study investigates the preparation and characterization of a novel HPMC-MCDs (Hydroxypropyl methylcellulose-magnetite carbon dots) composite film for potential applications in food safety monitoring. While dots (CDs) offer promising sensing capabilities, their inherent lack color limits direct visual detection, limitation addressed this work by incorporating magnetite (Fe 3 O 4 ) to create visually discernible sensor. Characterization techniques, including XRD, FTIR, SEM, confirmed successful integration MCDs within HPMC matrix. The incorporation significantly reduced film’s surface roughness. exhibited remarkably smooth surface. DFT calculations revealed enhanced stability composite. Fluorescence studies demonstrated change upon interaction with Salmonella enterica B. cereus , suggesting bacterial detection. Furthermore, pH-sensitive behavior, changing response pH variations, making it candidate monitoring beef meat spoilage. These findings suggest that have serve as multifunctional platform applications.

Abstract This study aimed to investigate the biodegradation behaviour of starch/nanocellulose/black tea extract (SNBTE) films in a 30-day soil burial test. The SNBTE were prepared by mixing commercial starch, nanocellulose (2, 4, and 6%), an aqueous solution black simple casting process. chemical morphological properties before after characterized using following analytical techniques such as field emission scanning electron microscopy (FESEM), energy-dispersive X-ray spectroscopy (EDX), fourier transform infrared (FTIR). changes composition, namely pH, electrical conductivity (EC), moisture content, water holding capacity (WHC), respiration, total nitrogen, weight mean diameter (MDW), geometric (GMD), result process, also estimated. results showed that exhibited considerable biodegradability (35–67%) within 30 days while increasing nutrients. addition reduced rate due its polyphenol which likely resulted reduction microbial activity. (2–6% starch) increased tensile strength, but decreased elongation at break films. These suggest starch are not only biodegradable under conditions positively contribute health, highlighting their potential environmentally friendly alternative traditional plastic packaging industry.

In efforts to resolve problems of depletion earth's resources and disposal solid waste caused by traditional petrochemical polyamide systems, biobased degradable polyamides their foamed products have received considerable attention. However, the practical development such sustainable foamable materials is still challenging. Herein, we designed an environmentally friendly elastomer system using 1010 (PA1010) as hard segment polycaprolactone (PCL) diol soft segment. By increasing PCL content, melting temperature was gradually suppressed from 205 173 °C, stretchability progressively enhanced 18 770%. Notably, elastomers with high contents were beneficial production lightweight foams expansion ratios higher than 3.8 via supercritical carbon dioxide (CO2) foaming, effectively overcoming major difficulties in manufacturing intrinsic issues crystallinity, low extensibility, insufficient melt strength. Moreover, controlling content at optimal value 37 wt % allowed achieve a good balance between foaming performance shrinkage resistance. Additionally, could be easily recycled remanufactured form renewed foam because no reactive cross-linkers or chemical blowing agents used. The compressive stress restored least 70% original level. Furthermore, gave favorable degradability. sample highest showed mass loss approximately 24.65% after 12 weeks alkaline medium. Such effective degradability conducive resolving accumulation landfilling greenhouse gas emissions incineration. We believe that these findings provide constructive way design advanced materials.
