Solvent sensitive organic/inorganic hybrid one-dimensional photonic crystals (1DPCs) were prepared through alternating thin films of poly methyl methacrylate-co-hydroxyethyl methacrylate-co-ethylene glycol dimethacrylate (PMMA-co-PHEMA-co-PEGDMA) and titania nanoparticle sol by spincoating. Since the titania layer has a higher refractive index compared with(More)
We report a giant Seebeck coefficient (S) thermoelectric (TE) material-MnO(2) powder-and the design of a practical MnO(2) TE generator to light up a regular light emitting diode (LED). The S of MnO(2) powder was measured to be higher than 20,000 μV K(-1), which is about 100 times higher than the state-of-the-art of Bi(2)Te(3), one of the best TE materials.(More)
OBJECTIVE The present study aimed at investigate the therapeutic effects of delayed puerarin treatment in neurological outcomes after middle cerebral artery occlusion (MCAO) in rats. MATERIALS AND METHODS Male Wistar rats were subjected to MCAO for 120 min followed by reperfusion for 14 days. Puerarin (0, 50, 100, 200 mg/kg, intra-peritoneally) was(More)
OBJECTIVE To estimate the intangible cost and associated factors on patients with hepatitis B-related diseases, so as to explore the differences of the three elicitation techniques on the 'willingness to pay approach' (WTP). METHODS Face-to-Face interviews were conducted to collect health economics-related information by trained investigators, using a(More)
Herein, we report a simple method to fabricate patterned organic/inorganic hybrid 1DPCs by top-down assisted photolithography. Versatile colorful pattern with different size and shape can be produced by selectively exposing the 1DPCs under UV light with predesigned photomask directly. The period change, especially the thickness variation of the top polymer(More)
We report a practical vacuum pressure sensor based on a ZnO nanowire array (NWA). An oriented single-crystal ZnO NWA was synthesized by electrodeposition. The device consists of two ITO glass plates coated with a ZnO NWA. Scanning electron microscopy (SEM) and the x-ray diffraction (XRD) pattern show that the as-grown ZnO NWAs are single-crystal and roughly(More)
Novel one-dimensional (1D) nanostructures of rare earth complexes (europium methacrylate (Eu(MA)(3))) have been prepared from the precursor of irregularly shaped Eu(MA)(3) powder in ethanol solvent without the assistance of an added surfactant, catalyst, or template. These hexagonal-shaped complex nanowires have diameters of about 100-300 nm and lengths(More)
In this work, the capacitive deionization (CDI) performance of a single-walled carbon nanotube (CNT) electrode has been studied from the point view of charge efficiency theory. It is revealed here that the charge efficiency of a CNT electrode is strongly dependent upon the cell voltage and solution concentration. Either the high cell voltage or the low(More)
