Development and characterization of genomic microsatellite markers in the tree species, Rhodoleia championii, R. parvipetala, and R. forrestii (Hamamelidaceae).

Rhodoleia Champion ex Hooker is one of the most primitive relict genera of Hamamelidaceae, a key family exploited to understand the origin and early evolution of flowering plants. Genomic simple sequence repeats (SSRs) were developed for R. championii to perform genetic diversity, phylogeographical structure or even systematic evolution studies of the genus.

Charge-induced electromechanical actuation of two-dimensional hexagonal and pentagonal materials.

Using first-principles calculations, we investigate electromechanical properties of two-dimensional (2D) hexagonal and pentagonal materials as a function of electron and hole dopings, in which 2D materials including graphene, chair-like graphane, table-like graphane, penta-graphene (PG), hydrogenated penta-graphene (HPG), and penta-CN2 are considered. We find that the actuation responses such as actuation strain, stress generated, and work area-density per cycle of the 2D materials in the case of hole doping are substantially larger than those of electron doping. Moreover, the electromechanical properties of the 2D materials can be improved by hydrogenation.

Charge-induced electromechanical actuation of Mo- and W-dichalcogenide monolayers.

Using first-principle density functional calculations, we investigate electromechanical properties of two-dimensional MX (M = Mo, W; X = S, Se, Te) monolayers with the 1H and 1T structures as a function of charge doping for both electron and hole doping. We find that by increasing the atomic number, , of X atoms ( < < ), the work density per cycle of the MX monolayers are increased and decreased for the 1H and 1T structures, respectively. On the other hand, the work density per cycle of the WX monolayers are higher than that of the MoX monolayers for both the 1H and 1T structures.
