TiO2 nanotubes generated by anodization of metallic titanium sputter-coated on indium tin oxide (ITO) substrates are used as a conductive scaffold for all solid-state Sb2S3-sensitized extremely thin absorber (ETA) solar cells. A blocking layer of TiO2 placed between Ti and ITO in combination with optimized Ti deposition and anodization conditions enables the formation of crack-free layers of straight, cylindrical TiO2 nanotubes of tunable length and diameter. ALD (atomic layer deposition) is subsequently used to coat this substrate conformally with a highly pure Sb2S3 light absorber layer under an inert atmosphere. The high absorption coefficient of Sb2S3 as compared to molecular dyes allows for the utilization of very short nanotubes, which facilitates the infiltration of the organic hole transport material and formation of a p–i–n heterojunction in an interdigitated and tunable geometry. We investigate the influence of nanotube length and of the absorber thickness to enhance the photocurrent value to twice that of planar reference structures.TiO2 nanotubes generated by anodization of metallic titanium sputter-coated on indium tin oxide (ITO) substrates are used as a conductive scaffold for all-solid-state Sb2S3-sensitized extremely thin absorber (ETA) solar cells. 相似文献

BackgroundChronic rhinosinusitis (CRS) has a high prevalence of anxiety and depression. It is currently uncertain if treatment in patients with CRS with or without nasal polyps (CRSwNP and CRSsNP) has any impact on improving mental health outcomes. The aims here were to document anxiety and depression in patients with severe CRS and asthma already treated with appropriate medical therapy. We then evaluated whether further maximal treatment with omalizumab improved anxiety and/or depression alongside improvements in CRS and coassociated asthma.MethodsHospital Anxiety and Depression Scale (HADS) scores along with measures of CRS and asthma severity were recorded according to CRSwNP and CRSsNP status in n = 95 patients with severe CRS and asthma. Of this group, a further n = 23 had omalizumab for associated allergic asthma. Follow‐up measures were collected 16 weeks after omalizumab treatment.ResultsHADS anxiety and depression prevalence in CRS were 49.47 % and 38.95%, respectively. Within the CRSwNP and CRSsNP group 53.06% and 45.66% had raised HADS‐anxiety scores. Abnormal HADS‐depression scores were present in 40.82% and 36.95% of the CRSwNP and CRSsNP groups, respectively. Correlations for sinonasal outcome test‐22 (SNOT‐22) versus HADS total was r = 0.59 p < 0.0001, HADS‐anxiety r = 0.56 p < 0.0001 and HADS‐depression r = 0.49 p < 0.0001. Omalizumab improved anxiety in CRS (p < 0.0001) regardless of nasal polyp status (CRSwNP p = 0.0042 and CRSsNP p = 0.0078). Depression scores did not improve in either group. SNOT‐22 (p = 0.0006), asthma control questionnaire‐7 (p = 0.0019) and mini‐asthma quality of life questionnaire including emotional function (p = 0.0003 and p = 0.0009, respectively) all improved in both subgroups.ConclusionIn CRS and asthma, anxiety scores but not depression improved after omalizumab treatment. Anxiety may be closely related to airway disease severity, but depression may be independent of airway disease itself. If so, a separate mental health care pathway is needed for CRS patients with depression. 相似文献

In highly dispersion compensated Fourier domain mode locked (FDML) lasers, an ultra-low noise operation can only be achieved by extremely precise and stable matching of the filter tuning period and light circulation time in the cavity. We present a robust and high precision closed-loop control algorithm and an actively cavity length controlled FDML laser. The cavity length control achieves a stability of ∼0.18 mHz at a sweep repetition rate of ∼418 kHz which corresponds to a ratio of 4×10−10. Furthermore, we prove that the rapid change of the cavity length has no negative impact on the quality of optical coherence tomography using the FDML laser as light source. 相似文献
