The journal seeks to promote and disseminate knowledge of the various topics and technologies of Polymer research in various sectors like industry, agriculture, health, water, shelter and environmental management. The journal will disseminate the research results among development policymakers, scholars and practitioners with a hope to identify new research directions. It can also have practical implications within interdisciplinary developing fields such as functional / specialty polymers, biomaterials, drug delivery, electronic applications, composites, conducting polymers, liquid crystalline materials; and bring contribution in new fabrication techniques.</p> http://lifescienceglobalca.com/index.php/jrups/article/view/9480 2024-02-02T16:01:49+00:00 Khadijah Husna Abd Hamid khadijah.husnaa@gmail.com Azilah Ajit info@lifescienceglobal.com Azren Aida Asmawi info@lifescienceglobal.com Mohd Hafiz Arzmi hafizarzmi@iium.edu.my Nurul Aini Mohd Azman ainiazman@umpsa.edu.my

<p>Plastic waste has become a significant global environmental issue, particularly in the context of food packaging. In the present study, active packaging films were fabricated by integrating chitosan-stabilized cinnamaldehyde Pickering emulsion (PE) and titanium dioxide particles (TNPs) into the semirefined carrageenan (SRC) matrix. The impact of cinnamaldehyde PE and TNPs on the physical and mechanical attributes of the SRC films was explored. The integration of TNPs (3%, w/v) and 0.5% cinnamaldehyde PE revealed promising mechanical properties, with 21.86 MPa tensile strength and 34.21% of elongation at break value. The inclusion of TNPs and cinnamaldehyde PE led to enhancements in the moisture content and water solubility of the SRC films. The thermal stability of the film was marginally increased with 0.5% cinnamaldehyde PE. Scanning electron microscopy (SEM) revealed a uniform distribution of active compounds in the SRC matrix. The study findings highlight the potential of cinnamaldehyde PE and TNPs in active food packaging films as eco-friendly alternatives to conventional petrochemical-derived plastics in food packaging.</p>

<p>Global competition in products and services demands constant improvement in production systems. Similarly, it is essential for industries to have quality control tools capable of assessing the compliance of a given product at a lower cost and with greater effectiveness. In the rubber and composite industry, where complex formulation and mixing systems can affect not only the quality of the final product but also the processing of rubber, the development of a protocol that assumes this function is important. The present study developed samples of elastomeric blends based on styrene-butadiene copolymer (SBR) with different filler concentrations (30, 60, and 90 phr of ground tire rubber as filler), which were analyzed using an oscillating cavity rheometer (MDpt-TechPro). Based on a proprietary testing protocol, the degree of homogeneity of the composites was evaluated, which was compared with scanning electron microscopy studies. The implemented protocol, which provides results within 30 minutes, proved to be promising for quality control of these blends, and it can be used by rubber processing industries, saving both time and cost, being an unprecedented study on the 'homogeneity-rheology' relationship.</p>
