In this work, aluminium-doped zinc oxide (AZO) was deposited via RF magnetron sputtering on glass substrates having different surface energies at room temperature. The different surface energies were developed by passivation of alkylsilane self-assembled monolayers (SAMs) with various hydrocarbon chain lengths on subs…
Radial heterojunction photodiodes based on a silicon nanowire arrays (SiNWs)-zinc oxide (ZnO) core-shell structure is demonstrated in this report. The heterojunction can be constructed by spin-coating ZnO nanoparticles onto SiNWs and a low temperature post-annealing process (<270 °C). The photodiode displays typical d…
Al-Cr-Fe coatings have been widely used in the surface engineering field of materials, due to their excellent corrosion resistance to water vapor and fused salt deposits. In this study, a new two-step approach was developed to prepare Al-Cr-Fe coatings on surfaces of SUS430 stainless steels. First, the Cr/Al composite…
Photoelectrodes were used to treat synthetic textile wastewater contaminated with indanthrene blue dye. Two media of treatment were used (NaCl and Na2SO4), with variations on temperature, pH, current density, dye and chloride concentration. A modified Pechini method was applied to obtain Ti/Ru-based electrodes (Ti, Ru…
Single-crystalline wurtzite ZnS nanobelts exhibiting enhanced narrow band-edge luminescence at room temperature have been synthesized readily through a one-step mild hydrothermal process involving ternary solvents of hydrazine, ethylenediamine, and water.
This study investigated the regeneration of waste edible oil using a food additive (calcium silicate, CAS). Waste edible oil was prepared by combined heat and aeration treatment. Moreover, the deterioration of edible oil by combined heat and aeration treatment was greater than that by heat treatment alone. The acid va…
Monodispersed BaAl2O4:Eu2+ nanospheres with 180 nm size were synthesized through forced hydrolysis using γ-Al2O3 nanospheres as a template followed by a subsequent heat treatment. The incorporation of a barium precursor onto an individual γ-Al2O3 template nanosphere was optimized by controlling the reaction time. The…
The high resistance to infections in lizard wounds suggests that these reptiles possess effective antimicrobial peptides in their tissues. The present immunocytochemical study shows the cellular localization of beta-defensin 27 in tail tissues and in the blood, a defensin previously identified in the lizard Anolis car…
Light emission in rare earth (RE)-free SnO–ZnO–P2O5 glasses is demonstrated. The RE-free transparent phosphate glasses show light emission with high quantum efficiency (QE) values, comparable to conventional crystalline phosphors, by excitation with deep-UV light. The broad emissions of the RE-free transparent glasses…

By a combination of the Rietveld full-profile fitting technique based on powder X-ray diffraction data and the single-crystal structure solving and refining method, one-dimensional infinite zigzag chain structures were observed in the structures of [Al2(OH)4(H2O)4]X2 (X = I, Br, Cl). These crystallize in the same mono…
Nanoplasmonic sensing as a powerful experimental technique for corrosion kinetics monitoring is demonstrated. Its versatility is illustrated by studies of initial corrosion carried out on model systems consisting of copper nanodisks and extended copper films in both dry (<0.5% relative humidity, RH) and humid (65 ± 5%…
The ability to switch the physico-chemical properties of conducting polymers opens up new possibilities for a range of applications. Appropriately functionalised materials can provide routes to multi-modal switching, for example, in response to light and/or electrochemical stimuli. This capability is important in the…
The crystal structure and electromagnetic properties of soft magnetic hexagonal ferrites for high frequency devices, and the practical use of Y- and Z-type ferrites are discussed. These X- and U-type ferrites were successfully synthesized, and their electromagnetic properties were investigated. Soft magnetic hexagonal…
This paper presents the preparation of carbon conditioned with iron nanoparticles (CI) using a pineapple peel treated with iron salts, carboxymethylcellulose sodium and hexamine. First, the pineapple peel was analyzed by thermo gravimetric analysis (TGA) to determine the optimal temperature for pyrolysis. The formatio…

We report an efficient and thermally stable material (4,4′-di(pyren-1-yl)-1,1′-biphenyl, DBP) for use as a deep-blue-emitting layer in organic light-emitting diodes (OLEDs) as well as an active channel layer in organic thin-film transistors (OTFTs). An OLED device doped with 3% DBP exhibited pure blue fluorescence emi…
Supercritical adsorption coupled with the high adsorption capacity of silica aerogel allows the preparation of a new kind of delivery systems of poor water soluble drugs. In order to overcome drawbacks of conventional techniques where the use of liquid solvents can cause the fracture of aerogel porous structure, in th…
A new coordination framework material, [Zn{MnN(CN)4(H2O)}]·2H2O·MeOH, has been characterised crystallographically and the effect of a terminal nitride on the N2, H2 and CO2 sorption capacities of the material assessed through porosimetery measurements and DRIFTS.
Samples of MoSi 2 -WSi 2 composite materials with additions of magnesium alumosilicates are obtained by solid phase sintering at 1650–1800°C in an argon atmosphere of powdered mixtures of initial components and disintegrated cast samples of 70% MoSi 2 –30% WSi 2 (Mo 0.7 W 0.3 Si 2 ), synthesized in an SHS reactor.
