Metabolic Alterations in Multiple Sclerosis
Pediatric Neurology Briefs, 1992 Alterations in regional cerebral metabolism have been demonstrated by in vivo proton magnetic resonance spectroscopy of 8 children (7 - 16 years) with established multiple sclerosis at the Max-Planck-Institut fur biophysikalische Chemie, Postfach, and ...

Advanced Functional Materials, EarlyView.Molecular engineering of a nonconjugated radical polymer enables a significant enhancement of the glass transition temperature. The amorphous nature and tunability of the polymer, arising from its nonconjugated backbone, facilitates the fabrication of organic memristive devices with an exceptionally high yield (>95%), as well as substantial ...

Multi-voxel proton magnetic resonance spectroscopy changes in neuropsychiatric lupus patients
South African Journal of Radiology, 2016 Purpose: In this prospective study, we used 2D chemical shift imaging (CSI), a multi-voxel proton spectroscopy technique, to evaluate the brain metabolites on conventional magnetic resonance imaging (MRI) in normal-appearing white and grey matter in ...

Advanced Functional Materials, EarlyView.A FeN4─O/Clu@NC‐0.1Ac catalyst containing atomically‐dispersed FeN4─O sites (medium‐spin Fe2+) and Fe clusters delivered a half‐wave potential of 0.89 V for ORR and an overpotential of 330 mV at 10 mA cm−2 for OER in 0.1 m KOH. When the catalyst was used in a rechargeable Zn–air battery, a power density of 284.5 mW cm−2 was achieved with excellent ...

Nanoscale Torsional Resonator for Polarization and Spectroscopy of Nuclear Spins [PDF]
, 2010 We propose a torsional resonator that couples to the transverse spin dipole of an attached sample. The absence of relative motion eliminates a source of friction that would otherwise hinder nanoscale implementation.
