Exceptional uranium(VI)-nitride triple bond covalency from 15N nuclear magnetic resonance spectroscopy and quantum chemical analysis

open access: yesNature Communications, 2021
Determining the nature and extent of covalency of early actinide chemical bonding is a fundamentally important challenge. Recently, X-ray absorption, electron paramagnetic, and nuclear magnetic resonance spectroscopic studies have probed actinide-ligand ...

Shiftless nuclear magnetic resonance spectroscopy [PDF]

open access: yesThe Journal of Chemical Physics, 2008
The acquisition and analysis of high resolution one- and two-dimensional solid-state nuclear magnetic resonance (NMR) spectra without chemical shift frequencies are described. Many variations of shiftless NMR spectroscopy are feasible. A two-dimensional experiment that correlates the C13α–N15 dipole-dipole and H1–C13α dipole-dipole couplings in the ...

Two-dimensional nuclear magnetic resonance spectroscopy with a microfluidic diamond quantum sensor [PDF]

open access: yesScience Advances, 2019
We demonstrate a microfluidic platform for multidimensional NMR using prepolarization and detection with a diamond quantum sensor. Quantum sensors based on nitrogen-vacancy centers in diamond have emerged as a promising detection modality for nuclear ...

Structural basis for interdomain communication in SHIP2 providing high phosphatase activity

open access: yeseLife, 2017
SH2-containing-inositol-5-phosphatases (SHIPs) dephosphorylate the 5-phosphate of phosphatidylinositol-3,4,5-trisphosphate (PI(3,4,5)P3) and play important roles in regulating the PI3K/Akt pathway in physiology and disease.
