Over the last twenty to thirty years composite materials has been used in engineering field. Composite materials possess high strength and high strength to weight ratio, and due to these facts composite materials are becoming popular among researchers and scientists. The major proportion of engineering materials consists of composite materials. Composite materials are used in vast applications ranging from day-to-day household articles to highly sophisticated applications. In this present investigation hybrid composites of Epoxy/Nanoclay/Glass fiber were prepared by Hand-layup technique. The glass fiber used in this present investigation is E-glass fiber bi-directional: 45° orientation). The composite samples were made in the form of a plate. The wt% of nanoclay added in the preparation of sample was varied, ranging from 1wt% to 5wt%. The fabricated composite materials in the form of plate were cut into corresponding profiles as per standards for impact testing

Overview of the present-day concentrated solar energy (CSE) technologies is presented. Approaches to concentrating solar energy are reviewed and the current projects worldwide of CSE technologies are compared. This paper presents general descriptions, current projects and summary of the CSE technologies. Parabolic trough collectors (PTCs) technology is found to be a mature technology. The linear Fresnel collectors (LFCs) technology is still in the experimental stage. The tower solar power (TSP) technology is preferred for large scale due to the cheapness. Sterling/dish collectors (SDCs) technology is designed especially for remote applications and has the highest overall efficiency and the highest operating temperature. The application areas show that CSE can be used in a wide variety of systems, could provide significant environmental and monetary benefits.

Packaging plays a crucial role in product transportation, storage, and safety, with materials evolving to meet modern demands. Plastic packaging dominates due to its versatility, while paper and metal alternatives are gaining traction due to recyclability and durability. Bioinspired packaging and damage-tolerant designs are emerging trends, with China leading in research. The COVID-19 pandemic has accelerated the demand for medical packaging, where the United States leads in innovation. Advances in biodegradable materials, including biopolymers, plant-based Fibers, and smart packaging, are shaping the future of the industry. While challenges such as cost, durability, and barrier properties persist, innovations in nanotechnology and active packaging are enhancing performance. The shift toward sustainability and the 3R principles—Reduce, Reuse, Recycle continues to drive research and industry transformation. Compliance with regulatory requirements is increasingly supported by emerging technologies, including IoT, blockchain, and cyber-physical systems. Innovations in medical packaging include nanotechnology for barrier protection, modified atmosphere packaging (MAP), and intelligent packaging (IP), enhancing product quality and safety. Key design considerations focus on tamper-evident features, sterilization, and user-friendly accessibility, especially for children and the elderly. Material selection prioritizes microbial sterility, barrier properties, and durability to ensure product integrity. Sustainability remains a critical focus, with increasing adoption of biodegradable materials and efforts to minimize environmental impact. Future research aims to address gaps in sustainable packaging, regulatory compliance, and advanced material development to further improve packaging efficiency, safety, and eco-friendliness in the medical and pharmaceutical industries.
