Hello,
I am a research scholar who is pursuing a PhD in materials engineering from the University of Hyderabad. I have come across crystalline chemistry and have attended courses on it as a part of my course work right from my bachelors days. Now, I can identify the material based on the diffraction spots of the crystal structures obtained in the X-ray Diffraction and transmission electron microscope (TEM) analysis. I generally do/did this as a part of the research work going on. So, I strongly believe that I can help you out in finishing your task. Please feel free to contact me if you think that I am capable of doing your job.
