Nuclear magnetic shielding anisotropies from proton multiple pulse spectra

, 1973
Proton multiple pulse spectra of powder samples of anhydrous oxalic acid, oxalic acid dihydrate, malonic-, succinic-, phthalic-, maleic- and fumaric acid. succinic-, phthalic- and maleic acid anhydride, and ferrocene have been recorded at 90 MHz.

Electric quadrupole polarisabilities of nuclear magnetic shielding in some small molecules [PDF]

, 2008
Computational procedures, based on (i) the Ramsey common origin approach and (ii) the continuous transformation of the origin of the quantum mechanical current density-diamagnetic zero (CTOCD-DZ), were applied at the Hartree-Fock level to determine ...

A Dual‐Functional Electrolyte Additive for Highly Reversible Zinc‐Ion Batteries

Advanced Functional Materials, EarlyView.
This study introduces tetrabutylammonium bromide (TBAB) as a dual‐function additive for aqueous zinc‐ion batteries. TBAB disrupts the hydrogen‐bond network of water while TBA+ adsorbs on Zn to improve interfacial wettability and regulate Zn2+ flux, resulting in suppressed dendrite growth and parasitic reactions. This synergy extended the lifespan of Zn|

Basis Set Convergence of Nuclear Magnetic Shielding Constants Calculated by Density Functional Methods

, 2016
The previously proposed polarization consistent basis sets, optimized for density functional calculations, are evaluated for calculating nuclear magnetic shielding constants. It is shown that the basis set convergence can be improved by adding a single p-

Magnetic Moments of Short-Lived Nuclei with Part-per-Million Accuracy: Toward Novel Applications of β-Detected NMR in Physics, Chemistry, and Biology

Physical Review X, 2020
We determine for the first time the magnetic dipole moment of a short-lived nucleus with part-per-million (ppm) accuracy. To achieve this 2-orders-of-magnitude improvement over previous studies, we implement a number of innovations into our β-detected ...

Development of a Three‐Axis Planar Hall Magnetoresistance Sensor Using a Superparamagnetic Nanoparticle‐Based Flux Guide

Advanced Functional Materials, EarlyView.
A printed superparamagnetic nanoparticle‐based flux guide enables the realization of a hysteresis‐free three‐axis magnetic sensor. This innovative architecture efficiently redirects out‐of‐plane fields to planar sensing elements, facilitating simultaneous vector detection without complex reset protocols.
