Polymeric Actions to Make Recycled Aggregate of Concrete Improved
Abstract: Recycling construction materials of concrete, steel, and steel scraps is an essential technique to promote sustainable material flow. The restricted reuse of recycled concrete aggregate (RCA) can be justified, even in part, by the impact on strength and durability of new RCA-based concrete, instead of natural aggregates. Various research has been conducted on improving RCA effectiveness, in particular resistance and water absorption to disintegration. Application of polymer-dependent therapy was used …

Engineering Sustainable Interior Materials: Performance Analysis of PLA Composites Reinforced with Banana Stem Fiber and Spent Coffee Grounds
Abstract: This study presents the development and classification of eco-friendly composite panels reinforced with spent coffee grounds (SCG) and banana stem fibers (BSF) for interior applications. Hybrid composites were fabricated using polylactic acid (PLA) as the matrix with a constant filler loading of 30 wt%, varying BSF:SCG ratios (70:30, 60:40, 50:50). Mechanical testing revealed that the 70:30 composite exhibited the highest tensile strength (42 MPa) and flexural strength (58 MPa), whereas …

Optimized Receivers for Underwater Visible Light Communication
Abstract: For uses like ocean exploration, environmental monitoring, and underwater data transfer, wireless communication under water is crucial. Conventional acoustic and radio frequency communication methods suffer from low bandwidth, high latency, and severe signal attenuation in underwater environments. With its high data rate and low propagation delay, Visible Light Communication (VLC) provides a promising alternative. In this work, an underwater VLC system is implemented using Light Emitting Diodes (LEDs) with intensity …

Development of a Durable Superhydrophobic EP/PDMS Coating Reinforced with Micro-CaCO₃ and Nano-ZnO for Enhanced Corrosion Protection and Multifunctional Performance on Carbon Steel
Abstract: Balancing exceptional multifunctional performance with mechanical robustness in micro-nano composite films remains a significant challenge for practical applications. In this work, a superhydrophobic coating reinforced with micro-CaCO₃ and nano-ZnO particles was fabricated through a versatile single-step brushing method. The optimized EP/PDMS@micro-CaCO₃/nano-ZnO coating achieved a water contact angle (WCA) of 173.54° ± 2.53° and a sliding angle (SA) of 1.50° ± 1.12°. Owing to its carefully engineered micro-nano hierarchical structure, the …
