Advanced Functional Materials & Aeromaterial Templates
As a research engineer at the National Center for Materials Study and Testing (NCMST), I contributed to the synthesis, processing, and high-resolution characterization of advanced nanostructures. This work was a core component of the Young Researchers Project #24.80012.5007.12TC, funded by the National Agency for Research and Development (ANACED), spanning 1.5 years from 2024 through 2025.
The Challenge: Synthesizing Next-Generation Ultra-Lightweight Aeromaterials
The primary objective of this project was the synthesis and structural engineering of novel, ultra-lightweight, high-porosity 3D networks (aeromaterials). The core challenges addressed by our research group included:
- Phase Stabilization: Controlling precise phase transitions between magnetite ($\text{Fe}_3\text{O}_4$) and hematite ($\text{Fe}_2\text{O}_3$) during high-temperature thermal treatments.
- Structural Integrity: Maintaining the ultra-low density macro-porous architecture of Gallium Nitride (GaN) nanonetworks when using sacrificial templates.
- Process Automation: Replacing inconsistent manual laboratory protocols with automated embedded setups to guarantee repeatable environmental conditions during electrochemical and redox cycles.
Research & Engineering Solution
To overcome these barriers, our team developed a hybrid approach combining chemical nanotechnology, custom automated laboratory setups, and high-resolution electron microscopy.
1. Advanced Material Processing
My responsibilities centered on designing and operating automated custom hardware systems to optimize the chemical pathways:
- Thermal Oxidation & Reduction: Utilizing automated PID-controlled thermal setups to handle precise ramp-up profiles, crucial for controlling the phase evolution of the iron oxide networks.
- Electrochemical Modification: Performing precise oxide formation on diverse sacrificial metallic substrates to establish uniform pore sizes.
- GaN Aeromaterial Templates: Investigating the uniform growth of semiconductor thin layers on lightweight porous templates intended for advanced optoelectronic and sensor applications.
2. Characterization & Morphological Validation
To evaluate the quality and crystalline layout of the resulting architectures, I performed extensive analysis utilizing advanced laboratory infrastructure:
- Scanning Electron Microscopy (SEM): Investigating surface topography, pore distribution, wall thickness, and microstructural damage.
- Redox Stability Studies: Observing how the microstructural skeleton of $\text{Fe}_3\text{O}_4$ networks reacts to continuous thermal and chemical stress.
Academic Dissemination
The scientific outcomes generated during this 1.5-year research initiative were compiled and presented to the international scientific community across multiple prestigious events:
