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)

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)
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)
Keywords: metallodielectric photonic crystal, brush block copolymer, gold nanoparticles, designable network structure of gold, thermally tunable optical properties Photonic crystals (PhCs) prepared via the self-assembly of block copolymers (BCPs) offer new opportunities for simple fabrication of flexible photonic devices or coatings in an inexpensive and(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)
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)
In this paper, hybrid film of mesoporous silica film with oriented mesochannels and semiconductor quantum dot has been prepared. Encapsulation of CdS and PbS within the oriented mesochannels leads to a regular arrangement at the macro scale. The hybrid film thus obtained showed remarkable anisotropic photoelectronic properties due to the confinement effect(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)
