Comprehensive stellar population models and the disentanglement of age and metallicity effects

, 1994
The construction of detailed models for intermediate and old stellar populations is described. Input parameters include metallicity (-2 less than (Fe/H) less than 0.5), single-burst age (between 1.5 and 17 Gyr), and initial mass function (IMF) exponent ...

Half-metallicity in single-layered manganese dioxide nanosheets by defect engineering.

Angewandte Chemie, 2015
Defect engineering is considered as one of the most efficient strategies to regulate the electronic structure of materials and involves the manipulation of the types, concentrations, and spatial distributions of defects, resulting in unprecedented ...

A Theoretical Prediction on the Intrinsic Half-Metallicity in the Surface-Oxygen-Passivated Cr2N MXene

, 2016
Two-dimensional Cr2N MXene as well as the surface-passivated Cr2NF2, Cr2N(OH)2 and Cr2NO2 are investigated by using density functional theory. The Cr2N is an anti-ferromagnetic metal.
