Evaluating Chassis Designs for Gesture-Driven Robots: A Study of Iron, Acrylic, and 3D Printed Solutions
Abstract: Gesture-driven robotic systems are becoming increasingly relevant in applications such as assistive technology, industrial automation, and interactive systems. The choice of chassis material plays a crucial role in determining the robot's mechanical strength, weight, and ease of fabrication. This study systematically evaluates three chassis materials—iron, acrylic, and 3D printed polymers—to determine their suitability for gesture-controlled robots. A standardized robotic configuration, including two rear motors, two front dummy axles, an L298N …

Recyclable Vitrimer-Matrix Carbon Fibre Composites for Aerostructures: Reprocessing Efficiency and Retention of Mechanical Performance
Abstract: To begin, carbon fiber reinforced polymers (CFRP) have become an important part of the structural loading in many modern aircraft; however, due to their permanent cross-linking in thermosets, they cannot easily be restored after being retired. Vitrimers have been proposed as a solution since their Covalent Adaptable Networks (CANs), rearranged by associative exchange, may be reshaped, welded, repaired or dissolved without damaging the CFRP fibers. This paper reviews whether the …

Polycystic Ovarian Syndrome and Its Management in Unani System of Medicine – A Comprehensive Review
Abstract: Polycystic ovarian syndrome (PCOS) is a prevalent endocrine disorder that significantly impacts women’s reproductive and metabolic health. It often leads to anovulation and infertility, creating distress for those affected. Additionally, PCOS increases the risk of developing diabetes and other long-term health complications. Recognizing and addressing PCOS is crucial, as early intervention can improve quality of life and prevent serious health issues. Common symptoms are polymenorrhea, oligomenorrhea, amenorrhea, hirsutism, acne, weight …

Mechanical Characterization of Prosopis Juliflora Fibre-Reinforced Epoxy Composites for Sustainable Automotive Applications
Abstract: This study investigates the potential of Prosopis juliflora (PJ) fibre as an eco-friendly, economical, and mechanically efficient reinforcement for epoxy-based polymer composites. Composite samples were produced using the compression moulding technique with epoxy-to-fibre weight ratios of 90:10, 85:15, and 80:20. Mechanical tests, including tensile, flexural, impact, and hardness evaluations, were conducted in accordance with relevant ASTM standards. The incorporation of PJ fibre resulted in significant improvements in the mechanical behaviour …

Fabrication and Characterization of Almond Skin Powder Reinforced PLA Based Composite Filaments for Fused Filament Fabrication
Abstract: Researchers around the globe are increasingly utilizing recycling methods to address waste generated from polymers, spurred by the dire need to deal with environmental challenges promoting sustainable practices. Polymers are having highly-stable long-chain polymer structure which makes it difficult to degrade easily posing many environmental and health challenges, hence, recycling of the polymers is the sole method to mitigate harmful effects. However, there has been relatively little focus on producing …

Fabrication and Characterization of PLA-CSP Composites via FDM for Biodegradable Food Packaging
Abstract: In light of the growing need for environmentally friendly alternatives to conventional plastic packaging, this study presents the design of a food-grade, biocompatible packaging material composed of Polylactic Acid (PLA) and packed with coconut shell powder (CSP). One of the most well-known thermoplastic polymers, PLA is produced from renewable resources like sugarcane or maize starch. Its nontoxicity, biodegradability, and adherence to food safety standards and regulations provide energy. Unfortunately, PLA's …

Interfacial Bonding Efficiency in Jute-Carbon Fiber Polyester Matrix Composites Evaluated Through Short Beam Shear and Interlaminar Fracture Toughness Testing
Abstract: The natural Fiber–synthetic Fiber hybrid composites are jute–carbon Fiber hybrid in polyester matrix which could be used in semi-structural applications of automotive, construction and marine industry as an eco-friendly and cost-effective alternative of conventional carbon Fiber reinforced polymer. But the hydrophilic nature of jute Fibers and the relatively inert surface of carbon Fiber's cause weak bonding at the interface of the polyester matrix, which causes premature delamination, poor interlaminar shear …

Diglycidyl Ether of Bisphenol A (DGEBA) Based Epoxy Sizing Agent Induces Surface Polarity in Carbon Fibers†
Abstract: Determination of the chemical structure and composition of the sizing agent is a challenge as its concentration is low, varying in the range from ~0.5 wt.% (for polyacrylonitrile, PAN, based carbon fibers) to ~1 wt.% (for pitch-based carbon fibers). Moreover, such a piece of knowledge is vital for designing compatible polymer matrices to prepare CFRPs for diverse applications. As a result, the sizing layer that is coated on the carbon …

Structure–Optical Property Correlation of Co-Doped TiO₂ and ZnO Nanofillers for Advanced Functional Composite Applications
Abstract: This study investigates the enhancement of the structural and optical properties of titanium dioxide (TiO₂) and zinc oxide (ZnO) nanoparticles through cobalt (Co) doping. Pristine TiO₂ and ZnO are widely studied metal oxides; however, their large band gaps and limited visible-light absorption restrict their performance in optoelectronic, photocatalytic, and environmental applications. Co doping is employed as an effective strategy to overcome these limitations by inducing band-gap narrowing, creating defect-related electronic …

Autonomous Agentic AI for Adaptive Cure Optimization and Defect Prevention in Thermoset Polymer Composite Manufacturing
Abstract: Thermoset polymer composites occupy a central position in modern structural manufacturing, from aircraft fuselages to wind-turbine blades. Despite progress in resin chemistry and fiber architecture, the “cure process” that transforms compliant preforms into load-bearing structures remains difficult to manage. Manufacturers encounter ‘voids’, “interlaminar delaminations”, and “spring-back distortion” when curing complex or thick-section parts. The cause is not ignorance of the relevant physics, but rather that ‘temperature’, ‘chemistry’, ‘rheology’, and ‘mechanics’ …
