This study aimed to assess the level of nitrogen species in patients presented with acute myocardial infarction and to relate the levels of nitrogen species to the infarction site. A total number of 113 patients admitted to the intensive care unit at Diyala Teaching Hospital. The patients were presented within 6 hours of pain onset and diagnosed as acute myocardial infarction using electrocardi...

n-Type bismuth vanadate has been identified as one of the most promising photoanodes for use in a water-splitting photoelectrochemical cell. The major limitation of BiVO4 is its relatively wide bandgap (∼2.5 eV), which fundamentally limits its solar-to-hydrogen conversion efficiency. Here we show that annealing nanoporous bismuth vanadate electrodes at 350 °C under nitrogen flow can result in n...

Introduction At a global scale, human activity has increased the flux of N two-fold (Vitousek et al. 1997), particularly driven by large scale fertiliser manufacturing (Fowler et al. 2013). Additionally, the ability to transport inputs and outputs cheaply and extensively has led to substantial growth in agricultural production over the past 50 years with an accompanying 40% increase in world po...

This work report on the structural and electrical characteristics of zinc oxide single crystal samples doped with antimony. Doping was carried out by antimony thermal diffusion at 1000 °C for periods of one and two hours under nitrogen environment from a solid source formed by antimony oxide. X-ray diffraction was used to determine the crystalline phases in samples and the structural change owi...

Preparation and characterization of different metal oxide (NiO, WO3, ZnO, SnO2 and Nb2O5) nanostructures for chemical sensing are presented. p-Type (NiO) and n-type (WO3, SnO2, ZnO and Nb2O5) metal oxide nanostructures were grown on alumina substrates using evaporation-condensation, thermal oxidation and hydrothermal techniques. Surface morphologies and crystal structures were investigated thro...

Editor,—The ABEK HgCO NO-P3 filter (Drager) has been Editor,—We read with interest the article by Smith and colleagues on the costs of sevoflurane and propofol anaesthesia. In today’s described as an effective method of scavenging nitric oxide and nitrogen dioxide. The filter contains microglass fibres coated with cost-conscious climate, cost analyses such as the one published recently by Smith...

Narcosis is a neurological syndrome that reduces capacities of divers. Although this phenomenon appeared at the end of 19th century, the mechanisms are not yet elucidated. The greatest technical problem is that these studies are carried out under hyperbaric conditions. Nitrous oxide is known to be an inducer of narcosis, at atmospheric pressure. The aim of this study is to compare two narcotic ...

Reaction of a nonheme iron(III)-peroxo complex, [Fe(III)(14-TMC)(O2)](+), with NO(+), a transformation which is essentially isoelectronic with that for nitric oxide dioxygenases [Fe(III)(O2˙(-)) + NO], affords an iron(IV)-oxo complex, [Fe(IV)(14-TMC)(O)](2+), and nitrogen dioxide (NO2), followed by conversion to an iron(III)-nitrato complex, [Fe(III)(14-TMC)(NO3)(F)](+).

Aqueous Energy-Storage Devices In article number 2201481, Chunlei Wang, Qichong Zhang, Qingwen Li, and co-workers develop an in-situ nitrogen doping strategy to fabricate nitrogen-doped vanadium dioxide/nitrogen-doped carbon heterostructures by pyrolyzation of the oxide/polypyrrole. The well-designed fiber electrode delivers impressive electrochemical performance extraordinary flexibility, both...
