Materials exist that are useful for gamma scintillation, radiation shielding, neutron‐gamma pulse shape discrimination (PSD), thermal neutron detection, or high refractive index applications. While certain materials have exhibited optimal performance for each of these applications, none achieve multiple functions.

Cross Carbonyl-Olefin Metathesis (XCOM) of Unactivated Olefins
A method for the olefination of aryl aldehydes with unactivated alkenes via cross carbonyl-olefin metathesis (XCOM) is described. Reaction of an aldehyde substrate and a cis-1,2-disubstituted or monosubstituted olefin with the HBF4 salt of 2,3-diazabicyclo[2.2.2]octane results in high-yielding olefination with exclusive trans stereoselectivity.

A novel system for micron‐scale analysis of energy deposition and response to low‐dose radiation
Abstract Background Micrometer‐scale evaluation of energy deposition is important for radiation protection and therapy as well as for advancing knowledge of responses to radiation in materials and biological systems. Due to the stochastic nature of radiation interactions, there is significant variation in energy deposition in micrometer‐sized targets ...

New beam hardened data correction and its application to artifact reduction in CT images
Abstract Background Beam hardening is an unavoidable phenomenon in polychromatic CT systems, where lower‐energy photons are preferentially absorbed as x‐rays pass through materials such as tissue, bone, and metal. This energy‐dependent attenuation, which conflicts with the monochromatic assumption in filtered back‐projection (FBP), produces artifacts ...

Abstract Purpose This work aims to create and validate a comprehensive set of test cases and 3D reference dosimetric datasets for model‐based dose calculation algorithms (MBDCAs) in permanent implant prostate brachytherapy. These test cases address the limits of the standard TG‐43 formalism towards improving dose evaluations in prostate cancer ...

ABSTRACT An accurate database of atomic fundamental parameters (FPs) is crucial for quantitative material analysis based on x‐ray fluorescence (XRF). Given the wide range of applications and the limited reliability of existing experimental FPs for the L subshells of platinum, we determined its partial L fluorescence yields and Coster–Kronig transition ...
