    Harnessing Marine and Agro-Waste Resources: Bioengineered Seaweed Polysaccharide–Coconut Films for Next-Generation Sustainable Packaging

    By N.Ravi Kumar, R.Suthan, A. Srithar, M.Chitra, M.Meena, B. Uma Maheswari, Nellore Manoj Kumar, Prashant Sunagar, T.S.Shanthi

    Abstract: The increasing demand for biodegradable alternatives to petroleum-based plastics has led to significant interest in marine biopolymer-based packaging materials. This study focuses on the development of eco-friendly biocomposite films by reinforcing carrageenan, extracted from Kappaphycus alvarezii, with alkali-treated coconut at varying loadings (5%, 10%, and 15% w/w). The films were fabricated via solvent casting and subjected to comprehensive characterization. Mechanical analysis revealed substantial enhancement in tensile strength from 21.3 MPa …

    High-Performance Aluminum Matrix Composites Reinforced with Graphene Nanoplatelets a Study on Mechanical and Thermal Behaviour

    By Indradeep Kumar, Arigela Sri Harsha, Vijayakumar B, T. Rajesh Kumar, Surrya Prakash DilliBabu, Thiyagesan M, Avinash Kumar, Prashant Sunagar, K. S. Babulal

    Abstract: This study investigates the effect of graphene nanoplatelets (GNPs) on the mechanical and thermal properties of aluminum matrix composites (AMCs) fabricated using the powder metallurgy route. Aluminum alloy Al-6061 powder was reinforced with varying GNP concentrations (0, 0.5, 1, 2, and 3 wt%), followed by uniaxial compaction and sintering. The influence of GNP content on the composite’s structural integrity, strength, and thermal behavior was thoroughly evaluated through tensile testing, hardness …

    Polymer-Based Transparent Conductive Composites for Flexible Solar Panel Coatings

    By P. Suresh Kumar, Krishnagandhi Pachiappan, J Ananth, M Pandikumar, Arigela Sri Harsha, Md Irshad Alam, A.Vijayalakshmi, Prashant Sunagar, Sapthagirivasan V

    Abstract: This study investigates the fabrication and characterization of polymer-based transparent conductive composites (PTCCs) tailored for flexible solar panel coatings using poly(methyl methacrylate) (PMMA) and poly(ethylene terephthalate) (PET) matrices reinforced with silver nanowires (AgNWs), multi-walled carbon nanotubes (MWCNTs), and PEDOT:PSS. The composites were synthesized through a solution blending and doctor-blade casting method followed by post-treatments to enhance interfacial bonding and conductivity. Optical transmittance values above 85% were achieved across all composite …
