This research develops low-cost gallium arsenide solar-cell manufacturing to accelerate global decarbonization. Gallium arsenide absorbs light far more efficiently than silicon, potentially enabling cheaper and less capital-intensive solar production. By improving scalable manufacturing methods, the work aims to reduce the cost of expanding renewable-energy infrastructure needed to combat climate change.

This research develops cavity-based methods for controlling thermal radiation by transforming random heat emission into coherent, directional thermal beams. Unlike traditional narrowband approaches, the technique enables broadband heat control using practical materials such as silicon and germanium, with potential applications in energy efficiency, waste-heat recycling, cooling technologies, and climate mitigation.

This research converts organic waste—empty fruit bunches, used cooking oil, and eggshells—into biofuel. Using eggshell-derived catalysts lowers energy requirements for pyrolysis, producing hydrocarbon-rich fuels. The approach addresses waste management while reducing reliance on fossil fuels, offering a sustainable and environmentally friendly alternative energy solution.

This research investigates zinc batteries as a safer, cheaper alternative to lithium batteries. By studying the microscopic passive layer formed between zinc and electrolyte, it identifies mechanisms that improve performance and prevent failure. The work aims to enable more reliable, ethical, and fire-safe energy storage technologies through detailed materials analysis.

By understanding microbial responses at the genetic level, it aims to design microbe-friendly capture systems that convert carbon dioxide into useful fuels.

Batteries charge slowly and degrade over time. This research develops advanced supercapacitors using novel 2D materials and water-based electrolytes. The resulting devices charge rapidly, store five times more energy than conventional supercapacitors, last over 50,000 cycles, and offer a fast, affordable alternative for electric vehicles and energy storage.

Rising global electricity demand requires materials that conduct efficiently at extreme temperatures. This research develops scalable metal–ceramic composite conductors with tunable electrical properties by controlling particle interfaces and packing. These materials overcome limitations of metals and semiconductors, enabling efficient, affordable energy technologies for high-temperature industrial applications.
