Can Nitrogen-13 Ammonia Kinetic Modeling Define Myocardial Viability Independent of Fluorine-18 Fluorodeoxyglucose? [PDF]
Objectives. The hypothesis of this study was that evaluation of myocardial flow and metabolism using nitrogen-13 (N-13) ammonia kinetic modeling with dynamic positron emission tomographic (PET) imaging could identify regions of myocardial scar and viable

Fluoride‐Free Molten Salt Hydrate‐Assisted Synthesis of MXene in Air Down to 150 °C
A novel low‐temperature shielded salt (LSS) approach enables the synthesis of MXenes in air at temperatures as low as 150 °C using MgCl2·6H2O/LiCl. This method demonstrates successful etching of challenging MXenes like Cr2CTx and Nb2CTx through the synergistic effects of Li+ ions and salt hydrate phase changes, while eliminating the need for inert ...

PET imaging of bacterial infections with fluorine-18-labeled maltohexaose.
A positron emission tomography (PET) tracer composed of (18)F-labeled maltohexaose (MH(18)F) can image bacteria in vivo with a sensitivity and specificity that are orders of magnitude higher than those of fluorodeoxyglucose ((18)FDG).

Rapid, efficient, and economical synthesis of PET tracers in a droplet microreactor: application to O-(2-[18F]fluoroethyl)-L-tyrosine ([18F]FET). [PDF]
BackgroundConventional scale production of small batches of PET tracers (e.g. for preclinical imaging) is an inefficient use of resources. Using O-(2-[18F]fluoroethyl)-L-tyrosine ([18F]FET), we demonstrate that simple microvolume radiosynthesis ...

This study introduces a highly soluble, reduction‐active lithium salt into conventional zinc battery electrolytes, enhancing the solvation structure and electric double layer. These modifications significantly improve the reversibility of the zinc anode and mitigate cathode material dissolution, presenting a novel approach to enhancing the performance ...

Production of Fluorine-18 by Small Research Reactor [PDF]
High purity 18F was prepared by irradiating 1 g of lithium hydroxide or otherwise 0.14 g of enriched lithium carbonate containing 50% 6Li in the pneumatic tube of a TRIGA-II research reactor at a thermal neutron flux of 1.2×1012 n/cm2-sec. After cooling for 20 min, the irradiated lithium hydroxide was dissolved in distilled water. The resulting 13F was
