Balancing Polysulfide Distribution in "Anode-Free" Lithium-Sulfide Batteries. [PDF]

ChemSusChem
“Anode‐free” lithium–sulfide batteries represent a sustainable concept to maximize a battery's specific energy. However, reactions between polysulfide species and the copper negative electrode can prevent their reversible operation. While this necessitates restricting the mobility of polysulfide species, a less effective migration barrier is herein ...

Clove Essential Oil Enhances Antioxidant Defenses and Reduces DNA Damage in a Cellular Model of Parkinson's Disease. [PDF]

Parkinsons Dis
Oxidative stress is a major contributor to the pathogenesis of Parkinson’s disease, promoting neuronal degeneration through the production of excessive reactive oxygen species. In this context, natural products such as essential oils are attracting increasing attention for their potential to protect neurons.

Evaluation of Software-Optimized Protocols for Acoustic Noise Reduction During Brain MRI at 7 Tesla. [PDF]

J Magn Reson Imaging
ABSTRACT Background MR‐generated acoustic noise may be particularly concerning at 7‐Tesla (T) systems. Noise levels can be reduced by altering gradient output using software optimization. However, such alterations might influence image quality or prolong scan times, and these optimizations have not been well characterized.

Improving the Accuracy and Repeatability of Renal Stiffness Measurement With Magnetic Resonance Elastography: Influence of Vibration Frequency, Acquisition Orientation, and Postprocessing-A Phantom and Volunteer Study. [PDF]

NMR Biomed
This study optimized a prototype MR elastography sequence for kidney imaging using standardized phantoms and translated it to in vivo application. Twenty‐one silicone phantoms (2–57.7 kPa stiffness) and five healthy volunteers were imaged using a prototype 2D‐gradient echo sequence at 1.5‐Tesla.

Two Key Ferredoxins for Nitrogen Fixation Have Different Specificities and Biophysical Properties. [PDF]

Chemistry
Two ferredoxins, FdC and FdN, are collectively essential for the process of nitrogen fixation by the iron nitrogenase in R. capsulatus. We explore the biophysical factors, through spectroscopic and structural characterizations, which determine ferredoxin functionality and pathway specificity. The structure of FdC (PDB: 9I2A) and model of FdN (AF‐D5ARY6)
