Portable, Benchtop and Micro‐XRF in Agriculture—Present and Future From the Hardware Perspective
X-Ray Spectrometry, EarlyView.ABSTRACT X‐ray fluorescence (XRF) spectrometry has been an important tool in agricultural studies recently. This technique allows the multielemental, direct, and in situ analysis. The objective of this review is to evaluate the use of XRF in agriculture focusing on plant and soil samples based on indexed articles in the Scopus database from 2020 to ...

The Stripping Method for X‐Ray Spectral Correction in ISO 4037‐1 Narrow Spectra Series (N10‐N150)
X-Ray Spectrometry, EarlyView.ABSTRACT Spectrometry is an important tool for the characterization of X‐ray beams in ionizing radiation metrology. However, the use of solid‐state spectrometers for accurate measurements requires correction of spectral distortions caused by the interaction between photons and the detector.

Conservation Biology, EarlyView.Abstract Biodiversity is globally threatened by human impacts, including land‐use transformation and climate change, which has prompted a rapid transition from fossil fuels to cleaner energy sources, such as photovoltaic (PV) energy. However, utility‐scale PV plants require vast areas and can lead to conflicts with biodiversity conservation, making ...
