Ionically assembled nanoparticles (INPs) have been formed from poly(ionic liquid-co-N-isopropylacrylamide) with deoxycholic acid through electrostatic interaction. The structure and properties of the INPs were investigated by using (1)H NMR, Fourier transform infrared (FTIR), transmission electron microscopy (TEM), dynamic light scattering (DLS), and so on.(More)
New types of fluorescent nanoparticles (FNPs) were prepared through ionic self-assembly of anthracene derivative and chitosan for applications as drug delivery carriers with real-time monitoring of the process of drug release. Because of the presence of the hydrophilic groups, these FNPs showed excellent dispersion and stability in aqueous solution. The(More)

Controlling of the orientation of mesochannels in mesostructured thin films is important for the development of novel molecular devices and, in particular, generating vertically aligned mesochannels with respect to the substrate plane is extremely challenging for nonsiliceous materials. We describe a facile and highly effective air flow method, which is(More)
A self-healing electrically conductive superhydrophobic poly(3,4-ethylenedioxythiophene) (PEDOT) coating has been prepared by chemical vapor deposition of a fluoroalkylsilane (POTS) onto a PEDOT film, which was obtained by electrochemical deposition. The coating not only maintained high conductivity with a low resistivity of 3.2 × 10(-4) Ω·m, but also(More)
We report that an exceptionally large volume of highly ordered arrays (single grains) on the order of millimeters in scale can be rapidly created through a unique innate guiding mechanism of brush block copolymers (BBCPs). The grain volume is over 10(9) times larger than that of typical self-assembled linear BCPs (LBCPs). The use of strong interactions(More)
A superhydrophobic polythiophene film (SSPTH) is prepared by double-layer electrodeposition on an indium tin oxide (ITO) glass electrode. This film shows not only electroresponsive superhydrophobic features, but also high transparency compared with the usual polythiophene film. The water-droplet adhesion on the SSPTH film can be switched between sliding and(More)
Mesoporous silica film with oriented mesochannels in three dimensions was supposed to have significant potential in preparing a new kind of optical or microelectronic device. Here we reported a new approach to preparing an oriented mesostructured silica film by just employing rapid and hot air flow. Based on this approach, 3D control of mesochannel(More)
BACKGROUND Successful treatment of missed Monteggia fractures usually requires ulnar osteotomy and open reduction of the radial head with reconstruction of the annular ligament. We have observed cases in which the annular ligament was displaced into the joint but remained intact. Here we report our experience with repositioning of the annular ligament at(More)
Oriented mesostructured silica films show potential for the design of nanostructured materials for applications in optics, electronics, and so on. In this report, we propose a new approach to control the orientation of mesochannels using a laser-modified polyimide surface. Pluronic 123 was employed as the structure agent, and mesostructured SBA-15-type(More)
