Direction-Controlled Light-Driven Movement of Microribbons.
Novel direction-controlled movements of microribbons self-assembled from perylene diimide molecules are reported on various hydrophobic surfaces under scanning laser irradiation. A "dynamic exciton charge model" is developed to elucidate the underlying mechanism. The findings provide an innovative strategy for the design of microscale systems capable of continuous and directional movement drive...
متن کاملArrangement of subunits in microribbons from Giardia.
Ultrasound has been used to disperse the cytoplasm of Giardia muris and Giardia duodenalis trophozoites, releasing disk cytoskeletons for negative staining and study by electron microscopy. Sonication also breaks down the corss-bridges uniting microribbons in disks. Individual ribbons and small bundles of these structures, are found in these preparations and have been imaged both from their edg...
متن کاملDislocation-driven nanowire growth and Eshelby twist.
Hierarchical nanostructures of lead sulfide nanowires resembling pine trees were synthesized by chemical vapor deposition. Structural characterization revealed a screwlike dislocation in the nanowire trunks with helically rotating epitaxial branch nanowires. It is suggested that the screw component of an axial dislocation provides the self-perpetuating steps to enable one-dimensional crystal gr...
متن کاملA visible light driven doped TiO2 nanophotocatalyst: Preparation and characterization
A useful nanophotocatalyst (La,S-TiO2) was prepared by a sol-gel method and characterized by UV–vis diffuse reflectance spectroscopy (DRS), X-ray diffraction (XRD), photoluminescence emission spectroscopy (PL) and scanning electron microscopy (FESEM). The results showed that the La,S-TiO2, which calcined at 550 °C, contained only anatase phaseand its crystal size was 23 nm...
