About Us ✍🏻

Our Core Research Pillars

1. Advanced Nanomaterials Synthesis & Characterization We specialize in the precise design, synthesis, and characterization of diverse semiconductor nanostructures using scalable and advanced methodologies, including molecular beam epitaxy (MBE), chemical bath deposition, microwave-assisted solvothermal processes, and hydrothermal methods.

• Low-Dimensional Semiconductors: We grow high-quality III-V compound nanowires (such as InP and GaAs) and intricate metal oxide structures (like ZnO nanorods and TiO2).

• Quantum Dots (QDs): Our team synthesizes varied QD systems, including PbS, GaSb/GaAs, and carbon/graphene quantum dots derived from both chemical precursors and biomass waste (like watermelon peels and Arabian dates) for unique optoelectronic and imaging applications.

• 2D Materials & Perovskites: We pioneer the development of 2D MXene sheets, transition metal phosphides (e.g., Ni2P), and lead-free double perovskites (like Cs2AgBiBr6) to push the boundaries of catalytic and optical performance.

2. Next-Generation Optoelectronics & Solar Energy We design highly efficient photovoltaic and optoelectronic architectures capable of operating under diverse lighting conditions, from direct sunlight to indoor local spectrums.

• Organic & Hybrid Solar Cells: We develop inverted organic solar cells (using polymers like P3HT:PCBM), enhancing their power conversion efficiency through the incorporation of carbon quantum dots, plasmonic bimetallic nanoparticles, and modified hole-transporting layers (like V2Ox).

• Photodetectors & Perovskite Photovoltaics: Our work includes fabricating low-dark-current organic photodetectors and exploring the bandgap engineering of thin-film CIGS and halide perovskite solar cells.

3. Innovative Sensor Technologies By leveraging the extraordinary surface-to-volume ratios and tunable bandgaps of our nanomaterials, we fabricate highly responsive and selective sensors for industrial, environmental, and medical use.

• Gas & Chemical Sensors: We engineer room-temperature optical sensors—such as palladium-coated tapered optical fibers—for sensitive hydrogen gas detection, alongside ZnO and graphene-polyaniline composites for ethanol, ammonia, and CO sensing.

• Environmental & Humidity Sensors: Our researchers utilize thermally evaporated organic molecules (like dicarbocyanine dyes and vanadium-based phthalocyanines) to create highly accurate humidity sensors. We also develop L-cysteine grafted fiber-optic sensors and ZIF-8 metal-organic frameworks (MOFs) for the trace-level detection and removal of heavy metals from water.

4. Energy Harvesting, Storage & Environmental Remediation Our group provides sustainable solutions to power small-scale electronics and remediate toxic industrial waste.

• Self-Powered Nanogenerators: We harvest ambient mechanical energy by fabricating piezoelectric and triboelectric nanogenerators (TENGs) using controlled growth of ZnO nanorod arrays and PVDF composites.

• Energy Storage: We develop flexible solid-state supercapacitors utilizing materials like sodium cholate-reduced graphene oxide, manganese dioxide nanowires, and carbon nanotubes.

• Photocatalysis & Water Treatment: We employ nanocomposites for highly efficient UV and sunlight-driven photodegradation of toxic pollutants. Recent breakthroughs include using MXene-anchored nanostructured nickel phosphide (Ni2P/MXene) for the rapid degradation of Reactive Black-5 dye, and utilizing g-C3N4/TiO2/CQD composites for robust environmental remediation. We also focus on scalable hydrogen water splitting using optimized electrocatalysts.
