Start with the scientific question.

X-ray diffraction

Which crystalline phases are present, and how strong is the evidence?

Interpret the measured pattern together with reference peaks, missing reflections, unexplained signals, structure data and refinement residuals.

Raman spectroscopy

Which vibrational features distinguish the material or state?

Review baseline treatment, peak position, width, intensity ratios and assignments without separating the interpretation from its preprocessing choices.

Photoluminescence

What do the emission peaks say about optical transitions and defects?

Compare corrected traces using wavelength, photon energy, FWHM, integrated intensity and centroid while retaining acquisition context.

Electron microscopy

Which morphology and size observations are supported by the image?

Keep scale calibration, region selection and measurement overlays visible so morphology claims remain reviewable instead of becoming detached annotations.

Surface topography

How does surface height vary, and which features are real?

Inspect topography, roughness, line profiles and local features with the scan area and processing history kept in view.

Battery performance

Which electrochemical signals explain performance and degradation?

Connect cycling, rate capability, efficiency and voltage behavior across cells and protocols before drawing a performance conclusion.
