Influence of Ni substitution on the phase transitions and magnetocaloric effect of NdCo2 at cryogenic temperatures

This study demonstrates that substituting Ni for Co in NdCo₂ suppresses the orthorhombic phase and reduces the magnetic moment, thereby decreasing the magnetocaloric effect at cryogenic temperatures.

Localized Exciton Emission with Spontaneous Circular Polarization in NiPS3/WSe2 Heterostructures

This study demonstrates that few-layer NiPS3/WSe2 van der Waals heterostructures exhibit spontaneous circularly polarized exciton emission and nonlinear Zeeman splitting due to interface-induced localization and magnetic proximity effects, as confirmed by low-temperature spectroscopy and DFT calculations.

Spin State versus Potential of Zero Charge as Predictors of Density-Dependent Oxygen Reduction in M-N-C Electrocatalysts

This study demonstrates that the potential of zero charge (PZC), rather than spin state, is the superior predictor for density-dependent oxygen reduction activity and selectivity in M-N-C electrocatalysts, as PZC-driven shifts in the interfacial electric field modulate adsorption energetics to explain performance trends across varying metal-site densities.
