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)
BACKGROUND Open reduction of the radial head is usually necessary in the treatment of a missed Monteggia fracture. However, the best way to stabilize the reduction remains controversial. The purpose of this study is to present our experience using the dual-socket external fixator to stabilize the ulna osteotomy and capture the reduction of the radial head.(More)
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)
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)
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)
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)
Fluorescent nanoparticles (FNPs) are obtained in water by self-assembly from a polymeric ionic liquid, fluorescent carboxylate moiety, and a surfactant through two main supramolecular interactions, that is, ionic bonds and hydrophobic/hydrophilic interactions. The hydrophobicity of the surfactant is tunable and a highly hydrophobic surfactant increases the(More)
A new strategy based on ionic self-assembly technology was provided for design of photosensitive material as liquid crystals (LC) alignment layer. The complex material was constructed by the coupling of poly(ionic liquid) and photosensitive unit azobenzene dye methyl orange. The structure, phase behavior and photoresponse were examined by a variety of(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)
