The geometries, electronic structures, and magnetic properties of H-, B-, C-, N-, O-, and F-absorbed MoS2 monolayers have been investigated by first-principles calculations. The results demonstrate that all these atoms can chemically absorb on MoS2 monolayer. The total magnetic moments of H-, B-, C-, N-, and F-absorbed MoS2 monolayers are 1.0, 1.0, 2.0, 1.0, and 1.0 μB, respectively. The large spatial extensions of spin density and long-range antiferromagnetic coupling were observed in H- and F-absorbed MoS2 monolayers. Additionally, the n-type and p-type two-dimensional MoS2 semiconductors can be realized by absorbing H and N atoms, respectively.

Growth differentiation factor (GDF11) is a member of TGF-β/BMP superfamilythat activates Smad and non-Smad signaling pathways and regulates expression of its target nuclear genes. Since its discovery in 1999, studies have shown the involvement of GDF11 in normal physiological processes, such as embryonic development and erythropoiesis, as well as in the pathophysiology of aging, cardiovascular disease, diabetes mellitus, and cancer. In addition, there are contradictory reports regarding the role of GDF11 in aging, cardiovascular disease, diabetes mellitus, osteogenesis, skeletal muscle development, and neurogenesis. In this review, we describe the GDF11 signaling pathway and its potential role in development, physiology and disease.

A novel five-coordinated Mn(II) polymer 1H-benzimidazole-5,6-dicarboxylato manganese (II) ([Mn(Hbidc)] n , 1) possessing abundant hydrogen bonds and π−π stacking interactions, synthesized by the hydrothermal reaction between MnSO4 and a multifunctional organic aromatic ligand H3bidc, displays antiferromagnetic character, strong long-lived red luminescence (λmax = 726 nm and τ = 0.3 ms) as well as high thermal stability (up to ca. 500 °C).
