Quantitative Assessment of Cold Injury in Tea Plants by Terahertz Spectroscopy Method

Agronomy, 2023
Cold injury (CI) causes irreversible damage to tea plants, which results in decline in the quality of famous teas and huge economic loss. A new, quick, non-destructive method is provided to assess the CI of tea leaf based on terahertz (THz) spectroscopy.

Analysis of hidden information - PLSR on XRD raw data [PDF]

Acta Crystallographica Section A Foundations and Advances, 2014
Usually in XRPD we are paying lots of attention to accurately describe profile shapes. We do that to eventually extract/predict information from the full pattern using physical models and fitting techniques. Sometimes this approach is stretched to its limits.
