AgCuO 2 nanoplates have been electrodeposited onto indium-tin oxide (ITO) coated glass near room temperature in an alkaline aqueous solution contained silver(I)/copper(II) ammonia complexes. The Ag(I)/Cu(II) ammonia complexes act as water or ammonia oxidation catalysts to generate acid and lower the local pH at ITO electrode, and then Ag + and Cu 2+ ions are partial oxidized and dissociated from complexes to react with OH − to form AgCuO 2 deposits on ITO. The electrodeposited AgCuO 2 are composed of single crystal cuboidal nanoplates with a preferential orientation along [−202] crystal axis. X-ray photoelectron spectra results indicate that the Ag and Cu ions in AgCuO 2 are partially oxidized to +3 valence states. The as-electrodeposited AgCuO 2 nanoplates show four distinct discharge processes at +0.28, +0.01, −0.42, and −0.67 V vs. Ag/AgCl.

Objective. Sjögren's syndrome (SS) is the most common autoimmune disease with dry eye (DE) syndrome and some systemic lupus erythematosus (SLE) patients are also with DE syndrome. The occurrence of immune-related DE disease is closely related to T helper (Th) 17 cells in SS patients, and SLE patients have abnormal levels of multiple Th17 cell-related cytokines in their blood. However, the degree of expression of these cytokines in blood differs from that in tears. We hypothesised that the occurrence of DE symptoms in SLE and SS patients may be related to Th17 cells. Methods. In this study, Th17 cell-related cytokines, including interleukin (IL)-1β, IL-2, IL-4, interferon-γ, IL 6, IL-8, IL-17F, tumour necrosis factor (TNF)-α, were analysed in tear samples of DE, SLE, and SS patients. Ocular surface examinations for patients with DE symptoms, including tear secretion test (Schirmer I Test, SIT) and tests for ocular surface disease index (OSDI), tear break-up time (BUT), and corneal fluorescein stain (CFS), were performed and compared between the following patient groups: normal healthy people (control group, n=30), patients with simple DE disease (DE group, n=13), SLE patients with DE disease (SLE group, n=17), and SS patients with DE disease (SS group, n=18). Results. The expression of Th17 cellrelated cytokines in each tear sample was analysed using Luminex assay. The SIT and BUT scores of the SLE group were lower than those of the control (p<0.001) and DE (p<0.05) groups. However, SIT, BUT, CFS, and OSDI scores were not significantly different between SLE and SS patients. TNF-α, IL-6, IL-8, and IL-21 levels in tear samples were higher in DE, SLE, and SS patients (p<0.05) than in con-related cytokines, such as IL-8 and IL-21, may be potential therapeutic targets for treating SLE or SS DE disease.

Thin CuI layer has been deposited on the electrodeposited Cu2O film through adsorption I− ions in 2 mM KI at room temperature and pH 3 and its effect on the photoelectrochemical properties of Cu2O has been studied. The electrodeposited Cu2O shows (100) preferential orientation and the chemical deposited CuI shows (111) preferential orientation. XPS results show that the Cu+ valence state dominated on the surface of Cu2O/CuI electrode instead of Cu2+ valence state dominated on the surface of Cu2O electrode. With optimum thickness of CuI layer, the photoelectrochemical response for Cu2O/CuI electrode is largely enhanced. The mechanism for the improvement of the photoresponse has been studied and could be due to positive shift of flatband, longer photogenerated electron lifetime, better charge transfer and less charge recombination for the Cu2O/CuI electrode.

Ag 3 PO 4 films were electrodeposited onto indium-tin oxide (ITO) coated glass through electrochemical generation of acid in a stable aqueous solution contained silver ammonia complexes and sodium phosphate at room temperature and pH 10. After the released H + ions lower the local pH at ITO working electrode, Ag + ions were dissociated from silver ammonia complex and then reacted with PO 43− to form Ag 3 PO 4 deposits on ITO. The morphologies of electrodeposited Ag 3 PO 4 films depended on the applied potentials: trisoctahedral like structure obtained at 1.2 V versus Ag/AgCl and tetrahedral structure obtained at 1.6 V versus Ag/AgCl. The absorption spectra of the electrodeposited Ag 3 PO 4 films were measured and they had direct and indirect band gaps of 2.43 eV and 1.99 eV, respectively. The electrodeposited Ag 3 PO 4 films produced stable sensitive photocurrent in response to visible light irradiation at pH 7.
