Dear friend Khaled F. El-Nemr

Ah, JPDS [XRD] reference? That's a crucial piece to the puzzle when comparing XRD patterns for activated carbon derived from agricultural waste. Here's the scoop: you Khaled F. El-Nemr want to dig into the literature and find a JPDS (Journal of Powder Diffraction Standards) reference that aligns closely with the material you're working with.

Start by hitting the databases. Look for articles or papers that have thoroughly characterized activated carbon samples using XRD. Once you've got your hands on a promising reference, scrutinize it closely. Pay attention to the methodology, sample preparation techniques, and, most importantly, the XRD patterns.

Compare those patterns to the ones you've obtained for your activated carbon. Look for similarities, differences, peaks, and trends. This comparison will help you Khaled F. El-Nemr gauge the structural properties and crystallinity of your material in relation to the established standards.

Remember, precision is key. Ensure your measurements are accurate, and your comparisons are meticulous. With a solid JPDS reference in hand, you'll be well-equipped to analyze and interpret your XRD data with confidence.

Dear Khaled F. El-Nemr

You can open your XRD analysis file in X'Pert HighScore Plus software and use its library search to compare standard cards to the phases you want.

Dear Khaled F. El-Nemr

To my knowledge, The Joint Committee on Powder Diffraction Standards (JCPDS) is now known as the International Centre for Diffraction Data (ICDD). So you can search for the pattern in the ICDD database. Most files from the ICDD database are also published in journals, so you can compare your pattern with those journals and use them as a reference. However, using X'Pert HighScore Plus software for matching your XRD pattern with a standard database is the easiest  way to get JCPDS reference.
