description: Biopolymer composites have gained significant attention in biomedical engineering due to their biocompatibility, biodegradability, and mechanical tunability, making them promising candidates for next-generation implantable devices. However, the gap between laboratory-scale fabrication and clinically reliable performance limits their widespread adoption. This study explores the systematic fabrication, structural optimization, and mechanical characterization of biopolymer composites intended for orthopedic, dental, and soft-tissue implants. Fabrication involved blending natural and synthetic biopolymers with bioactive reinforcements to improve strength, stiffness, and long-term stability. Mechanical behavior was assessed under tensile, compressive, flexural, fatigue, and impact conditions to evaluate suitability for load-bearing and semi-load-bearing applications. Microstructural imaging and degradation experiments further revealed how reinforcement dispersion and polymer crystallinity influence performance. Results show that tailored composite formulations can achieve mechanical properties comparable to conventional implant materials while offering superior biological integration and reduced risk of inflammatory response. This work strengthens the scientific foundation for developing safe, durable, and clinically viable biopolymer- based implants that align with future biomedical advancements and personalized medicine.

Durability and Environmental Performance Testing of Eco-Friendly Construction Materials under Field Conditions
type: item
description: Eco-friendly construction materials are central to sustainable infrastructure, yet their long-term performance under real environmental exposure is still insufficiently validated. Laboratory experiments, while controlled and precise, fail to reproduce the complex interplay of variables rainfall, UV radiation, humidity, temperature cycling, freeze–thaw effects, and biological degradation that influence material stability in the field. This research investigates the durability and environmental behavior of four major sustainable materials: compressed stabilized earth blocks (CSEB), fly ash–based geopolymer concrete, recycled aggregate concrete, and natural fiber composites. Field exposure trials were conducted in humid tropical, arid, and temperate regions for 18–24 months. Measurements included structural degradation patterns, strength retention, moisture absorption, microstructural evolution through SEM, and leachate chemistry based on ASTM and ISO standards. Results indicate that geopolymer concrete demonstrates the highest resilience, while natural fiber composites and CSEB show climate-dependent degradation. Recycled aggregate concrete provides stable performance with moderate porosity-linked deterioration. Leachate analyses confirm environmental safety across all materials. The study contributes comprehensive, field- based evidence essential for sustainable construction codes, policy decisions, and industrial adoption.

type: item
description: The rapid increase in environmental variability and climate-related challenges has intensified the need for efficient, scalable, and autonomous monitoring systems. Wireless Sensor Networks (WSNs) provide a promising solution for real-time environmental surveillance due to their distributed architecture, low power consumption, and ability to operate in remote or inaccessible regions. This study presents the design, deployment, and comprehensive performance evaluation of a multi-node WSN used to monitor temperature, humidity, air quality, and soil moisture. The system architecture integrates low-power IEEE 802.15.4 communication, mesh-based routing, and calibrated environmental sensors. Field experiments were conducted over twenty days under varying atmospheric and terrain conditions to analyze packet delivery ratio, latency, throughput, and energy consumption. Results indicate that while the WSN demonstrated stable performance with a packet delivery ratio above 90 percent during optimal conditions, environmental obstructions and rainfall caused noticeable degradation in signal strength and network reliability. The findings align with established studies on the vulnerabilities of WSN communication to environmental interference. Overall, the deployed system exhibited strong potential for long-term environmental monitoring applications, including precision agriculture, pollution analysis, and smart city infrastructures. Future improvements should integrate energy harvesting modules, adaptive routing algorithms, and enhanced self-healing capabilities for extended autonomous operation.
