“…The obtained diffractograms for single-layered MTTFs treated at different temperatures between 350-550 • C are shown in Figure 4. Reference patterns of anatase TiO 2 [82], rutile TiO 2 [83] and SnO 2 [84] (as a representative for FTO) are included for reflex assignment and a diffractogram of a blank FTO/glass substrate was measured to identify the contribution of the FTO to the recorded diffractograms. The observed reflexes in the blank FTO diffractogram can be explained with the used reference pattern of SnO 2 in its rutile modification [84].…”

This work aims at the identification of porous titanium dioxide thin film (photo)electrodes that represent suitable host structures for a subsequent electrodeposition of plasmonic nanoparticles. Sufficient UV absorption and electrical conductivity were assured by adjusting film thickness and TiO 2 crystallinity. Films with up to 10 layers were prepared by an evaporation-induced self-assembly (EISA) method and layer-by-layer deposition. Activities were tested towards the photoelectrochemical oxidation of water under UV illumination. Enhanced activities with each additional layer were observed and explained with increased amounts of immobilized TiO 2 and access to more active sites as a combined effect of increased surface area, better crystallinity and improved transport properties. Furthermore, films display good electrochemical and mechanical stability, which was related to the controlled intermediate thermal annealing steps, making these materials a promising candidate for future electrochemical depositions of plasmonic noble metal nanoparticles that has been further demonstrated by incorporation of gold.

“…Anatase and rutile were not detected apart from the sediment background upstream at km −5.6 in the <1 and 1-250 µm sample fractions from October 2017 (Figure 3A). The presence of TiO 2 in the canal sediments at the Industrial Effluent and WWTP discharge sites was confirmed, with clear signals observed from both the anatase and rutile main peaks at 29.443 and 31.982 2Θ[ • ], respectively (Figure 3A) (Swanson et al, 1969). Of note, the main quartz peak at 31.035 2Θ[ • ] is also shown for reference.…”

“…The A I B II C V material was crushed into a fine powder under argon, and loaded into a zero-background sample holder with a layer of Biaxially-oriented polyethylene terephthalate (BoPET), known as Mylar s over the top of the material, and sealed for protection from moisture in the air. Each scan was collected on a Bruker D8 ADVANCE diffractometer equipped with Cu radiation using a Bragg Brentano geometry, and was compared to experimental data cited in the International Center for Diffraction Data (ICDD) database [2,24,29]. Additionally, the phase identification patterns were calculated for both LiZnP and LiZnAs with PowderCell 2.4 [30] with experimental lattice constants and space groups determined by Bacewicz [24] shown in Fig.…”

a b s t r a c tResearch for a reliable solid-state semiconductor neutron detector continues because such a device has not been developed, and would have greater efficiency, than present-day gas-filled 3 He and 10 BF 3 neutron detectors. Further, a semiconductor neutron detector would be more compact and rugged than most gas-filled or scintillator neutron detectors. The 6 Li(n,t) 4 He reaction yields a total Q value of 4.78 MeV, a larger yield than the 10 B(n,α) 7 Li, and is easily identified above background radiation interactions. Hence, devices composed of either natural Li (naturally 7.5% 6 Li) or enriched 6 Li (approximately 95% 6 Li) may provide a semiconductor material for compact high-efficiency neutron detectors. A sub-branch of the III-V semiconductors, the filled tetrahedral compounds, known as Nowotny-Juza compounds (A I B II C V ), are desirable for their cubic crystal structure and semiconducting electrical properties. These compounds were originally studied for photonic applications. In the present work, Equimolar portions of Li, Zn, and P or As were sealed under vacuum (10 À 6 Torr) in quartz ampoules with a boron nitride lining, and loaded into a compounding furnace. The ampoule was heated to 200 1C to form the Li-Zn alloy, subsequently heated to 560 1C to form the ternary compound, LiZnP or LiZnAs, and finally annealed to promote crystallization. The chemical composition of the synthesized starting material was confirmed at Galbraith Laboratories, Inc. by Inductively Coupled Plasma Optical Emission Spectroscopy (ICP-OES), which showed the compounds can be reacted in equal ratios, 1-1-1, to form ternary compounds. Recent additions to the procedure have produced higher yields, and greater synthesis reliability. Synthesized powders were also characterized by x-ray diffraction, where lattice constants of 5.751 7 .001 Å and 5.939 7.002 Å for LiZnP and LiZnAs, respectively, were determined.
