  • Hydrogen ion sensing characteristics of IGZO/Si electrode in EGFET

    In–Ga–Zn–O (IGZO) was widely applied in the substrate of TFT to replace α–Si in recent years. In this study, IGZO layer with thickness of 70 nm is firstly proposed as a pH–sensing membrane directly deposited on P–type Si substrate acting as an extended gate of conventional extended–gate field–effect transistor (EGFET). Post–deposition rapid thermal anneal (RTA) was performed to improve pH sensing ...

  • Analysis of a complex produced in the Fenton oxidation process

    The absorbances of different concentrations of Fe2+, Fe3+ and H2O2 were investigated by UV-visible spectrophotometry without separating the substances. The law of complex formation was studied by considering changes in the UV-vis spectra of mixtures of these three substances. The results show that upon eliminating the influence of the substrate, an ...

  • Novel catalytic and mechanistic studies on wastewater denitrification with hydrogen

    The present work reports up-to-date information regarding the reaction mechanism of the catalytic hydrogenation of nitrates in water media. In the present mechanistic study, an attempt is made, for the first time, to elucidate the crucial role of several catalysts and reaction parameters in the mechanism of the NO3−/H2 reaction. Steady-state isotopic transient kinetic ...

  • Decolorization of methyl orange by green rusts with hydrogen peroxide at neutral pH

    Heterogeneous Fenton-like processes using green rusts (GRs) with hydrogen peroxide (H2O2) were studied to decolorize methyl orange (MO) in aqueous solution at an initial pH of 7.0. In this study, two types of crystal structure for GRs, the hydroxycarbonate GR(CO32–) (GR1) and the hydroxysulphate GR(SO42–) (GR2), were synthesized ...

  • Inactivation of Ascaris eggs in water using hydrogen peroxide and a Fenton type nanocatalyst (FeOx/C) synthesized by a novel hybrid production process

    Inactivation tests of Ascaris eggs (Ae) were performed using hydrogen peroxide and a Fenton type nanocatalyst supported on activated carbon (AC) (FeOx/C). Blank inactivation tests were also carried out using H2O2 and H2O2/AC as oxidation systems. The FeOx/C nanocatalyst was synthesized through a novel hybrid method developed in this work. The ...

  • Declining Cost of Hydrogen Production Leads to its Increased Popularity

    Hydrogen fuel technologies have been on everyone's mind for quite some time now. However, due to the cost of hydrogen production, these technolgies have yet to be employed. With new techniques to produce hydrogen, the cost is declining and the efficiency is on the rise. By using renewable energy source for the hydrogen generation, there are virtually no emissions, leaving no carbon footprint. ...
