Numerical Analysis of the Mechanical Response of Two-Phase Nanocomposites Consisting of Nanoporous Gold and Polymer.

In this work, representative volume elements (RVEs) of composites, consisting of nanoporous gold and polymer, were investigated. Gold is of great interest as a special case of nanoporous metals as it deforms to large plastic strains when compressed, whereas normally nanomaterials allow only small deformations. The nanocomposite is modeled as a nanoporous monocrystal filled with a polymer.

A taxonomic revision of the genus (Selaginellaceae) from Nepal.

The present paper deals with the taxonomy of from Nepal based on the examination of herbarium collections housed in major herbaria of Europe and Asia (with additional collections from virtual herbaria). A total of 25 species are recognised here, while and are two new records for the flora of Nepal, India (Sikkim) and Bhutan; Selaginella monospora var. ciliolata is synonymised to ; detailed descriptions, distribution and ecology and IUCN conservation status assessments (based on literature) are presented.

(Selaginellaceae), a new spikemoss from China.

A new species of spikemoss from Yunnan Province of China, , is described and illustrated based on evidence from gross morphology, micromorphology and molecular phylogeny. is most similar to in its habit of creeping stem, leaf size, and obviously dimorphic sporophylls, but is distinct by its ventral leaves ovate-oblong, subcordate at base, basiscopic base entire, axillary leaves ovate and decurrent at base. Molecular phylogeny analysis of three chloroplast gene regions () shows that forms an independent branch with strong support which is distantly related to and , but sister to which is quite different in habitat of erect or ascending stem and rhizophores restricted to the lower part, and slightly dimorphic sporophyllus.
