Tin‐based perovskite light‐emitting diodes: Progress and perspective

InfoScience, EarlyView.
This review assesses tin‐based perovskite light‐emitting diodes (PeLEDs), focusing on the limitations of Sn2+ oxidation–induced defects and uncontrolled crystallization. By evaluating advanced device engineering and structural innovations, this article highlights their viability in narrowband pure‐red displays and near‐infrared optical communication ...

Acute Effects of Smoking and Vaping on Markers of Vascular Function via Quantitative MRI

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background E‐cigarettes contribute to endothelial dysfunction, a known cause of systemic atherosclerotic disease that cannot be adequately characterized by a single physiological parameter measured at a single vascular bed. Purpose/Hypothesis Quantify and compare acute effects of smoking or vaping with tobacco cigarettes (t‐cigs), nicotinized ...

Diffusion MRI of the Body: Beyond PGSE‐EPI

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Diffusion magnetic resonance imaging (dMRI) is a widely used clinical imaging technique which is sensitive to changes in tissue microstructure including cellularity, perfusion, and tissue damage. DMRI has been used in whole‐body imaging as well as in targeted imaging of every major anatomical region.
