We present an experiment examining effects of gaze on speech during three-person conversations. Understanding such effects is crucial for the design of teleconferencing systems and Collaborative Virtual Environments (CVEs). Previous findings suggest subjects take more turns when they experience more gaze. We evaluated whether this is because more gaze(More)
A novel cysteic acid modified carbon paste electrode (cysteic acid/CPE) based on electrochemical oxidation of L-cysteine was developed to simultaneously determine ofloxacin and gatifloxacin in the presence of sodium dodecyl benzene sulfonate (SDBS). Fourier transform infrared spectra (FTIR) indicated that L-cysteine was oxidated to cysteic acid.(More)
A highly sensitive and selective nonenzymatic glucose sensor based on electrodepositing NiO nanoparticles on ordered mesoporous carbon (named as NiO/OMC) modified glassy carbon electrode (GCE) was constructed. The synthesized OMC was characterized by X-ray diffraction, and the morphology images of OMC nanoparticle and NiO/OMC nanocomposite were(More)
In this study, the cooperative antibacterial efficiency of CdTe quantum dots (QDs) and rocephin against Escherichia coli (E. coli) was investigated. Colony-forming capability assay and diameter of inhibition zone (DIZ) measurement showed the antibiotic action of CdTe QDs-rocephin complex was better than the superposition of pure CdTe QDs and rocephin. The(More)
Human papillomavirus (HPV) is associated with cervical cancer. In this study, we developed a high-throughput microwell-plate hybrid capture (MPHC) method for epidemiological studies of high-risk HPV (HRHPV). The results with 1238 cervical specimens from female outpatients showed a concordance rate of 94.3 % between the MPHC and Hybrid Capture II assay. The(More)
PHBV microsphere/45S5 bioactive glass (BG) composite scaffolds with drug release function were developed for bone tissue engineering. BG-based glass-ceramic scaffolds with high porosity (94%) and interconnected pore structure prepared by foam replication method were coated with PHBV microspheres (nominal diameter=3.5 μm) produced by water-in-oil-in-water(More)
A mild and novel preparation tactics based on electrochemical techniques for the fabrication of electro-deposited graphene (E-GR) and polymerized β-cyclodextrin (P-βCD) nanocomposite film were developed. The structure and morphology of GR-based nanocomposite were investigated by scanning electron microscopy (SEM), transmission electron microscopy (TEM) and(More)
A novel nitrite sensor was fabricated based on a graphene/polypyrrole/chitosan nanocomposite film modified glassy carbon electrode. The nanocomposite film was characterized by scanning electron microscopy, Fourier transform infrared spectroscopy and Raman spectroscopy. The electron transfer behaviour of the modified electrodes was investigated in(More)
An electrochemical sensor for fluoroquinolones (FQs) based on polymerization of β-cyclodextrin (β-CD) and L-arginine (L-arg) modified carbon paste electrode (CPE) (P-β-CD-L-arg/CPE) was built for the first time. Synergistic effect of L-arg and β-CD was used to construct this sensor for quantification of these important antibiotics. Scanning electron(More)
A novel Au-nanoparticles/poly-eriochrome black T film modified glassy carbon electrode (AuNPs/PEBT/GCE) was constructed for the simultaneous determination of l-cysteine (L-Cys) and l-tyrosine (L-Tyr) by differential pulse voltammetry. Fourier transform infrared spectra and electrochemical impedance spectroscopy indicate that the PEBT film was successfully(More)
