Dye-sensitized solar cells (DSSCs) were fabricated using multiwalled carbon nanotube (MWCNT)-TiO(2) nanocomposite as a light scattering layer. Morphology of the MWCNT-TiO(2) film was investigated by field emission scanning electron microscopy (FESEM) and transmission electron microscopy (TEM). FESEM and TEM images demonstrate that MWCNTs and TiO(2)(More)
Adipose-derived stem cells (ASCs) secrete several angiogenic growth factors and can be applied to treat ischemic tissue. However, transplantation of dissociated ASCs has frequently resulted in rapid cell death. Therefore, we aimed to develop a thermosensitive chitosan/gelatin hydrogel that is capable of ASC sustained release for therapeutic angiogenesis. By(More)
This paper proposes a fully distributed, density-control, and multi-hop dynamic maintenance algorithm (DCMA) to repair the coverage holes in wireless sensor networks. Decision and movement of the nodes are autonomous and involve only limited distance to maintain the connectivity. While maintaining the coverage and connectivity, the proposed algorithm aims(More)
