“…Horta et al (2015) argued that using SLR, PXRF estimations of Pb (concordance correlation coefficient = 0.59) and Zn (concordance correlation coefficient = 0.51) were in good agreement with ICP measurements after aqua regia extraction. Moreover, researchers have also shown that principal component analysis can be efficiently utilized to separate metals, indicating their respective sources (Chakraborty et al, 2016).…”

Portable X‐ray fluorescence (PXRF) spectrometry is a proximal sensing technique whereby low‐power X‐rays are used to make elemental determinations in soils. The technique is rapid, portable, and provides multi‐elemental analysis with results generally comparable to traditional laboratory‐based techniques. Elemental data from PXRF can then be either used directly for soil parameter assessment (e.g., total Ca, total Fe) or as a proxy for predicting other soil parameters of interest (e.g., soil cation‐exchange capacity [CEC], soil reaction, soil salinity) via simple or multiple linear regression. Importantly, PXRF does have some limitations that must be considered in the context of soil analysis. Those notwithstanding, PXRF has proven effective in numerous, agronomic, pedological, and environmental quality assessment applications.

“…Low-cost and high-sensitivity X-ray detectors are of great interest in many elds, including scientic research, medical imaging, nondestructive detection, security, and defense. [1][2][3] Compared with commonly used rigid X-ray detectors, exible Xray detectors are more attractive because they can be applied on irregular surfaces and reduce image distortion caused by uneven distribution of X-ray beams, thus limiting misdiagnosis and errors in medical treatments. Unlike visible light, X-ray beams cannot be focused.…”
