NV Center Electron Paramagnetic Resonance of a Single Nanodiamond Attached to an Individual Biomolecule [PDF]
, 2015 A key limitation of electron paramagnetic resonance (EPR), an established and powerful tool for studying atomic-scale biomolecular structure and dynamics is its poor sensitivity, samples containing in excess of 10^12 labeled biomolecules are required in typical experiments.

High-field optically detected nuclear magnetic resonance in GaAs [PDF]
Appl. Phys. Lett. 86, 182103 (2005), 2005 A method for high-field optically detected nuclear magnetic resonance (ODNMR) is developed sensitive to 10**8 nuclei. Nuclear spin transitions are induced using a radio frequency coil and detected through Faraday rotation spectroscopy. Unlike conventional ODNMR, which is limited to low fields and relies on the measurement of time-averaged luminescence ...

Artificial Receptor in Synthetic Cells Performs Transmembrane Activation of Proteolysis
Advanced Biology, EarlyView.Transmembrane signaling is the hallmark of living cells and is among the highest challenges for the design of synthetic cells. Herein, an artificial receptor based on the chemistry of self‐immolative linkers is used to communicate information across the lipid bilayer, for transmembrane activation of enzymatic activity. Abstract The design of artificial,

lrSVD: An efficient imputation algorithm for incomplete high‐throughput compositional data
Journal of Chemometrics, Volume 36, Issue 12, December 2022., 2022 Abstract Compositional methods have been successfully integrated into the chemometric toolkit to analyse and model different types of data generated by modern high‐throughput technologies. Within this compositional framework, the focus is put on the relative information conveyed in the data by using log‐ratio coordinate representations.

Spatial Imaging and Mechanical Control of Spin Coherence in Strained GaAs Epilayers [PDF]
, 2005 The effect of uniaxial tensile strain on spin coherence in n-type GaAs epilayers is probed using time-resolved Kerr rotation, photoluminescence, and optically-detected nuclear magnetic resonance spectroscopies. The bandgap, electron spin lifetime, electron g-factor, and nuclear quadrupole splitting are simultaneously imaged over millimeter scale areas ...

E‐selective Semi‐hydrogenation of Alkynes under Mild Conditions by a Diruthenium Hydride Complex
Chemistry – A European Journal, Volume 28, Issue 69, December 9, 2022., 2022 Two do the job: Diruthenium hydrido carbonyl complexes bound to a PNNP expanded pincer ligand are described. Deprotonation of the methylene linkers enables cooperative activation of H2 allowing for the E‐selective semi‐hydrogenation of internal alkynes under mild conditions. Initial insights into the mechanism and the isolation of a deactivated species
