Abstract

Titanium dioxide, as a promising photocatalytic material, has been widely used in the fields of environmental pollution control and photocatalytic water splitting to generate hydrogen. In this paper, graphene and N-doping TiO2 composite film (GR/N-TiO2) electrode had been grown on titanium foil by one-step anodization, which was simple, time-saving and low cost. The electrode surface was lotusroot-like nanoclusters structure, which had a large specific surface area. The electrode exhibited an excellent optical absorption from ultraviolet to near infrared (200-2500 nm). This was due to the synergistic effects of graphene and N element, and the presence of oxygen vacancy defects. The results showed that the electrode had good electrochemical performances under simulated sunlight, its photocurrent density was about 0.7 mA/cm2, the light conversion efficiency was 0.35 %, and the hydrogen production rate was 34 μmol h-1cm-2. Thus, the prepared GR/N-TiO2 film electrode had an excellent hydrogen production activity under sunlight and the potential of converting solar energy into hydrogen energy directly.

Abstract

Objectives: The aim of this study was to evaluate the sensitivity and specificity of autofluorescence bronchoscopy (AFB) according to the macroscopic appearance of airway lesions under white light bronchoscopy (WLB). Materials and Methods: The bronchoscopic findings of 708 patients, who were pathologically and clinically diagnosed with airway lesions and underwent both WLB and AFB, were analyzed. Results: We recruited 708 patients for this study, of which 336 (47.5%) had benign lesions; 300 and 254 benign lesions were detected by AFB (specificity, 89.3%) and WLB (specificity, 75.6%), respectively. In 372 (52.5%) patients with bronchiogenic carcinoma, 356 and 235 lesions were identified by AFB (sensitivity, 95.7%) and WLB (sensitivity, 63.2%), respectively. The sensitivity and specificity of AFB for diagnosing lung cancer were higher than those of WLB (P < 0.05). Moreover, AFB showed high sensitivity for detecting lung cancer in cases in which WLB revealed hyperplasia, infiltration, and stenosis (P < 0.05). Conclusions: AFB combined with WLB could effectively improve the diagnosis of airway lesions. [ABSTRACT FROM AUTHOR]

29. Preparation and Photocatalytic Performance of TiO2/Modified Expandable Graphite Composite Material

Author

Wang, Hong Lun, Deng, Qin, Liu, Hui, Zhou, Yan Zi, and Zhang, Yan Zong

Abstract

In this paper, TiO2/modified expandable graphite composite material was prepared through sol-gel method with the carrier of modified expandable graphite.The influence of this composite material prepared in different calcination environment and with different times of load on the effect of methyl orange solution’s photocatalytic degradation was studied. Results show that the photocatalytic effect is better by using the composite material with the same times of load in aerobic calcination than that in anaerobic calcination. In the same calcination environment, the photocatalytic effect with 5 times of load is better than that with 1, 2, 3 and 4 times of load. Whether in the aerobic calcination or in the anaerobic calcination, the photocatalytic effect is better if the composite material is loaded 5 times.
