The mechanism of diatom locomotion has been widely researched but still remains a hypothesis. There are several questionable points on the prevailing model proposed by Edgar, and some of the observed phenomena cannot be completely explained by this model. In this paper, we undertook detailed investigations of cell structures, locomotion, secreted mucilage,(More)
The controllable growth of partially aligned monolayer to multilayer micrometer stripes was demonstrated by adjusting the pulling speed in a dip-coating process. The number of molecular layers decreases with the increasing pulling speed. A lower pulling speed yields mixed multilayers (3-9 monolayers). It is noteworthy that pure monolayer and bilayer(More)
Since their invention in 1987 by Tang et al, [ 1 ] small-molecule organic light-emitting diodes (OLEDs) have been the subject of intense scientifi c and technological investigation for applications ranging from lighting [ 2 ] and displays [ 3 ] to sensors. [ 4 ] Although monocolor OLEDs are suffi cient for some applications, color integration on a single(More)
We report here an enhancement in photovoltage for dye-sensitized solar cells (DSSCs) where halogen-bonding interactions exist between a nucleophilic electrolyte species (I(-)) and a photo-oxidized dye immobilized on a TiO2 surface. The triarylamine-based dyes under investigation showed larger rate constants for dye regeneration (kreg) by the nucleophilic(More)
Chlorogenic acid (CGA) exhibits various biological properties, including the inhibition of oxidation, obesity, apoptosis and tumorigenesis. CGA is also able to promote cell survival and proliferation. The aim of the present study was to determine the effects and underlying molecular mechanisms of CGA on the adipogenesis of bone marrow‑derived mesenchymal(More)
2010 WILEY-VCH Verlag Gmb Growing scientific effort is being devoted to building electronic circuits entirely or partially of organic materials because of their attractive characteristics such as low cost, light weight, and mechanical flexibility. To realize low-cost and high-performance organic transistor circuits for practical applications, utilization of(More)
Weak epitaxy growth (WEG) behavior and mechanism of copper hexadecafluorophthalocyanine (F16CuPc) on p-sexiphenyl (p-6P) monolayer film were investigated by atomic force microscopy (AFM), selected area electron diffraction (SEAD), and wide-angle X-ray diffraction (WAXD). High-quality F16CuPc films with high order, large size, and molecular-level smoothness(More)
The stabilities of three organic dyes that differ only by two substituents (-OMe, -H and -Br) about the phenothiazine donor unit were evaluated when immobilized on a semiconductor surface. All three dyes delivered modest power conversion efficiencies (PCEs) in the dye-sensitized solar cell (DSSC), but maintained 75% of their initial PCE over 300 h of(More)
