Research interest:

My research interests align closely with the Sustainable Development Goals (SDGs), specifically focusing on Goal 13 (climate action), Goal 11 (sustainable cities and communities), Goal 6 (clean water and sanitation) and Goal 7 (renewable energy sources). I am dedicated to the application of ferroelectric ceramics for energy harvesting and environmental sustainability. My research encompasses material synthesis and its potential for water cleaning through photocatalysis and piezocatalysis. By employing various synthesis routes, such as solid-state reaction, electrospinning, hydrothermal synthesis, and melt-quenching, I aim to develop high-efficiency, cost-effective catalysts. Additionally, I investigate the antibacterial properties of these materials and their practical applications in clean energy and environmental technologies, contributing to the broader goals of sustainable development and renewable energy utilization.

Key findings

This research presents the first study on laser-induced crystallization to prepare glass ceramics for water-cleaning applications. In previous reports, glass crystallization was accomplished through heat treatment at a specific temperature determined by performing differential scanning calorimetry (DSC). The new method proposed in this study offers advantages in terms of speed, control, less damage, less contamination, and miniaturization for the crystallization of glass ceramics.
