Calibrating Iodine Cells for Precise Radial Velocities [PDF]
High fidelity iodine spectra provide the wavelength and instrument calibration needed to extract precise radial velocities (RVs) from stellar spectral observations taken through iodine cells. Such iodine spectra are usually taken by a Fourier Transform Spectrometer (FTS).

Quantitative detection of iodine in the stratosphere
Significance Aircraft measurements in the lower stratosphere indicate iodine is efficient at destroying ozone in the gas and particulate phases. Active iodine chemistry in the upper troposphere–lower stratosphere (UTLS) is the result of convective ...

Non-metal Single Iodine Atom Electrocatalysts for the Hydrogen Evolution Reaction.
Single-atom catalysts (SACs) are attractive for various reactions because of their unique properties. However, common metal-based SACs are quite difficult to design due to the complex synthesis processes required.

High-Throughput Computational Screening and Interpretable Machine Learning of Metal-organic Frameworks for Iodine Capture [PDF]
The removal of leaked radioactive iodine isotopes in humid environments holds significant importance in nuclear waste management and nuclear accident mitigation. In this study, high-throughput computational screening and machine learning were combined to reveal the iodine capture performance of 1816 metal-organic framework (MOF) materials under humid ...

High-Sensitivity Iodine Imaging by Combining Spectral CT Technologies [PDF]
Spectral CT offers enhanced material discrimination over single-energy systems and enables quantitative estimation of basis material density images. Water/iodine decomposition in contrast-enhanced CT is one of the most widespread applications of this technology in the clinic. However, low concentrations of iodine can be difficult to estimate accurately,

Iodine deficiency and excess coexist in china and induce thyroid dysfunction and disease: a cross-sectional study. [PDF]
BACKGROUND: In spite of the salt iodization, iodine deficiency disorders (IDD) have not been sustainably eliminated in China. There are coastal areas with low iodized salt coverage rates (iodine nutrition is inadequate) and other areas with excessive ...
