Titania nanotube arrays decorated with WO3 (WTN) were fabricated by a chemical bath deposition (CBD) technique in combination with a pyrolysis process. The products were uniform and the amount of tungsten can be easily adjusted by the deposition time. The resultant hybrid nanotubes arrays were c...

A photochromic (PC) device comprising an electrochromic film (WO3) together with a photoactive film (usually, dye sensitized TiO2) coated on glass and a redox electrolyte (e.g., iodide/triiodide together with lithium salt) reduces the optical transmission under solar illumination and bleaches, a...

Herein we designed a simple and effective method for synthesizing carbon nanodots/tungsten trioxide nanocomposite with high photocatalytic activity. The as-prepared carbon nanodots/ tungsten trioxide has strong photoabsorption under visible light irradiation. Then, carbon nanodots/tungsten triox...

The mechanism of the electrochemical reduction of vanadium trioxide (V2O3) towards the formation of metallic vanadium in molten NaF-AlF3 salts was investigated by cyclic voltammetry and constant potential electrolysis. The porous V2O3 precursors were prepared from ammonium polyvanadate through c...

A novel type of TiO2/WO3 core/shell nanoarrays film as a good electrode material with superior performance has been successfully synthesized by hydrothermal and sol-gel method. The advantage of core/shell structure and the electrochromic behavior of the film have been discussed. The effects of a...

In this work, we investigated the stability of arsenic trioxide (ATO) used in leukemia treatment, encapsulated with nanoliposome, with the aid of ultrasound treatment. Stability studies of As species were followed by liquid chromatography-inductively coupled plasma mass spectrometry (LC-ICP-MS),...

A simple strategy for synthesizing silver-loaded titanium dioxide-tungsten trioxide nanotubes film for use as recyclable photo catalyst is introduced. Highly ordered and uniformly distributed titanium dioxide-tungsten trioxide nanotubes (WTNTs) on pure titanium were successfully fabricated by on...

Dititanium trioxide (Ti2O3) films with thickness between 13 and 100 nm on glass substrates were prepared by electron beam gun evaporation at low temperature. They were characterized by transmittance absorbance and reflectance curves. The optical properties of film include band gap calculation, b...

Mercury (Hg) enrichment in stratigraphic successions is now widely used as a proxy for volcanic inputs, often for the purpose of documenting a relationship between large igneous province (LIP) magmatism and ecosystem perturbations. Earlier studies of Hg in Ordovician/Silurian boundary (OSB) sect...

Bis(N-benzyl-N-furfuryldithiocarbamato-S,S′)mercury(II), [Hg(bzfdtc)2] (1) and bis(N,N-difurfuryldithiocarbamato-S,S′)mercury(II), [Hg(dfdtc)2] (2) were synthesized and characterized by IR, NMR and single-crystal X-ray crystallography. Single-crystal X-ray structures of 1 and 2 indicate that b...

Three new phenylmercury(II) dithiocarbamate complexes incorporating the furyl moiety, namely (N,N-difurfuryldithiocarbamato-S,S′)phenylmercury(II) (1), (N-furfuryl-N-(4-chlorobenzyl)dithiocarbamato-S,S′)phenylmercury(II) (2), and (N-furfuryl-N-(2-phenylethyl)dithiocarbamato-S,S′)phenylmercury...

The sulfidogenic process driven by sulfate-reducing bacteria (SRB) is not suitable for mercury-contaminated wastewater treatment due to the highly toxic methyl-mercury (MeHg) produced by SRB. In our previous study, we observed in short-term batch tests that sulfur-reducing bacteria (S0RB) could ...

Mercury is one of the elements which had attracted the attention of the chemists and physicians of ancient India and China. Among the various metal based drugs which utilize mercury, we became interested in the red sulfide of mercury which is known in ancient Indian literature as rasasindur (ali...

Utilization of impregnated carbons (silver/sulfur/iodide) for mercury removal is common, however with limitations in adsorption capacity and application. Continued efforts to develop porous sorbents with better mercury adsorption capacity and kinetics are evident from open literature with the re...

To detect the mineral diversity of a planet's surface, it is essential to study the spectral variations over a broad wavelength range at relevant simulated laboratory conditions. The MESSENGER (Mercury Surface, Space Environment, Geochemistry, and Ranging) mission to Mercury discovered that...

Octahedral cationic manganese(II) complexes having formulae [Mn(dppmO2)3]2+ and [Mn(dppeO2)3]2+, where dppmO2 and dppeO2 are respectively bis(diphenylphosphino)methane dioxide and 1,2-bis(diphenylphosphino)ethane dioxide, showed intense orange emission upon excitation with UV light, with photolu...

Bacterial Mn(II) oxidation plays an important role in the biogeochemical cycling of manganese and many trace metals. This study describes Mn(II) oxidation by two isolated manganese (Mn)-oxidizing strains that were identified and assigned as Brevibacillus brevis MO1 and Brevibacillus parabrevis M...

The extensive applications of biogenic manganese oxides (BioMnOx) generated by manganese oxidizing bacteria (MOB) have attracted considerable attentions. In this study, we report on a novel MOB that has been isolated from sediments and identified as Aeromonas hydrophila strain DS02. The Mn(II) o...

Sustainable energies are usually intermittent and if solar energy is to become an energy source in future, energy-storage systems are necessary. A reasonable solution to store solar energy is artificial photosynthesis with energy stored in chemical bonds such as molecular hydrogen. Among differe...

The aim of this study was to evaluate the treatment of organic-carbon-deficient wastewater containing benzotriazole (BTA) in lab-scale aerated biofilters filled with natural manganese oxide ore, sand coated with synthetic manganese oxides and sand (as a control material) in terms of BTA removal ...
