Evaluation of Some Parameterization Models for Photon Cross Sections in Quantitative Dual‐Energy CT

X-Ray Spectrometry, EarlyView.
ABSTRACT Using multienergy CT with energy‐dispersive detectors and dual‐energy CT (DECT), traditional CT images can be combined to extract material parameters such as electron density (ρe) and effective atomic number (Zeff). This study evaluates parameterizations for deriving ρe and Zeff from CT numbers (HU) to generate new CT images.

Metals' Adsorption Onto Environmental Microplastics at Shoreline Sediments

X-Ray Spectrometry, EarlyView.
ABSTRACT This study assessed trace element concentrations and microplastic (MP) contamination in three sandy beaches on the southern coast of Ilha Grande (Rio de Janeiro, Brazil). Environmental MPs were manually extracted from sand samples, and beaches were classified using the microplastic pollution index (MPPI).

Trace Element Analysis in Human Neuroblastoma Cell Spheroids Supplemented With ZnCl2 by Micro‐XRF

X-Ray Spectrometry, EarlyView.
ABSTRACT Neuroblastoma, the most common extracranial solid tumor of childhood, is responsible for ~10% of pediatric cancer deaths and has high potential for metastasis. Metals are extremely important in biological processes, and changes in their levels have been correlated with the development of cancerous growth.
