Parahydrogen‐Induced Polarization of Amino Acids [PDF]
Angewandte Chemie International Edition, 2021 AbstractNuclear magnetic resonance (NMR) has become a universal method for biochemical and biomedical studies, including metabolomics, proteomics, and magnetic resonance imaging (MRI). By increasing the signal of selected molecules, the hyperpolarization of nuclear spin has expanded the reach of NMR and MRI even further (e.g. hyperpolarized solid‐state

Magnetically Induced Polarization in Centrosymmetric Bonds [PDF]
Physical Review Letters, 2021 We reveal the microscopic origin of electric polarization $\vec{P}$ induced by noncollinear magnetic order. We show that in Mott insulators, such $\vec{P}$ is given by all possible combinations of position operators $\hat{\vec{r}}_{ij} = (\vec{r}_{ij}^{\, 0},\vec{\boldsymbol{r}}_{ij}^{\phantom{0}})$ and transfer integrals $\hat{t}_{ij} = (t_{ij}^{0 ...

Sensors, 2022 Airborne transient electromagnetic (ATEM) technology is a technique often used in mineral exploration and geological mapping. Due to inductive polarization (IP) phenomena, the ATEM response curve often shows a negative response or declines rapidly to the

Inductive source induced polarization [PDF]
Geophysical Journal International, 2012 We present a new survey methodology to map the distribution of chargeable material in the subsurface using inductive electromagnetic sources and observations of the magnetic fields in the frequency domain. An accompanying inversion algorithm is developed, and the technique is tested on synthetic data.

Effects of passivation configuration and emitter surface doping concentration on polarization-type potential-induced degradation in n-type crystalline-silicon photovoltaic modules [PDF]
, 2021 System voltages can cause significant degradation in photovoltaic modules. Polarization-type potential-induced degradation (PID) is accompanied by decreases in the short-circuit current density and the open-circuit voltage.
