Three new species of Primulina (Gesneriaceae) from limestone karsts of China based on morphological and molecular evidence

specific epithet is derived from the white maculation along the veins. Additional specimens examined CHINA. Guangdong Province, Yangchun City, Shiwang Township, 11 April 2014, Wei-Bin Xu & Bo Pan 11949 (IBK ... ); the same locality, 13 August 2012, Wei-Bin Xu et al. 11853 (IBK). Notes Primulina maculata is very similar to P. eburnea (Hance) Y.Z Wang in overall morphology but can be easily distinguished from the

The electronic structure and optical properties of Mn and B, C, N co-doped MoS2 monolayers

The electronic structure and optical properties of Mn and B, C, N co-doped molybdenum disulfide (MoS2) monolayers have been investigated through first-principles calculations. It is shown that the MoS2 monolayer reflects magnetism with a magnetic moment of 0.87 μB when co-doped with Mn-C. However, the systems co-doped with Mn-B and Mn-N atoms exhibit semiconducting behavior and...
