Rooftop Rainwater Harvesting Systems for Enhancing Climatic Resilience in the Dry Zone of Sri Lanka: A Case Study of Polpithigama Division, Kurunegala District
Rooftop Rainwater Harvesting (RWH) systems are critical interventions for addressing water scarcity in climate-vulnerable, water-stressed regions. In Sri Lanka’s dry zone, these systems have been promoted for over two decades to support communities facing seasonal droughts and limited access to surface water. This study evaluates the performance and socio-environmental impact of RWH systems in the …
Green Synthesis of Nanomaterials: A Sustainable Approach in Material Science: Review
Nanomaterials are commonly known as materials engineered with at least one dimension less than 100 nm in size. Due to these nanoscale dimensions, nanomaterials exhibit significantly different physicochemical properties compared to their bulk counterparts. […] This mini review critically examines “green synthesis” as a sustainable and eco-friendly approach for nanomaterial fabrication. This mini review clarifies …

Advancing Sustainability: Exploring the Role of Innovative Engineering Materials in Addressing Environmental Challenges
Global warming is rising at an unprecedented rate. This rapid increase is primarily due to human activities and the widespread use of fossil fuels for energy. […] This research paper examines a range of sustainable engineering materials, including advanced materials, biomaterials, recycled plastics and reclaimed wood, focusing on their properties and applications. It also highlights …
Toward Commercial Viability: A Comprehensive Review of Organic Solar Cell Stability and Scalability
This review paper provides a general overview of Organic Solar Cells (OSCs), more precisely their instability and commercialization challenges. […] Despite significant advances made, with power conversion efficiencies (PCEs) over 20% under laboratory conditions, the biggest challenge for wide-scale commercialization remains poor device stability and scalability. […] Notably, the synergistic effect of optimizing the active …
Joint Beamforming and Phase Shift Optimization in IRS-Aided NOMA Communications in 6G Networks
The paper explores the joint optimization of beamforming and phase shifts in Intelligent Reflecting Surface (IRS)-aided Non-Orthogonal Multiple Access (NOMA) systems within the context of 6G networks. We propose a novel algorithm that optimizes the beamforming vectors at the base station (BS) and the phase shifts at the IRS to maximize the sum rate of …
