Nonenzymatic nitrite sensor based on a titanium dioxide nanoparticles/ionic liquid composite electrode

Toward point-of-care management of chronic respiratory conditions: Electrochemical sensing of nitrite content in exhaled breath condensate using reduced graphene oxide

“…Nitrite oxidation-based methods with a final product of NO 3 are usually preferred because the presence of interfering molecules (such as oxygen) during reduction can be avoided 33 . However, an oxidation reaction as the basis for detecting nitrite requires a high over-potential 34 ; thus, in recent years, many attempts have been made to develop novel electrode materials [35][36][37][38][39][40][41][42][43][44][45][46][47][48] .…”

Modification of Proton Velocity Distributions by Alfvénic Turbulence in the Solar Wind

“…As is explained in our accompanying paper (Voitenko and Pierrard, 2012), a timevarying diffusion can lead to the beam formation by the time-of-flight effects. The beams can be also produced by the proton trapping and acceleration in the parallel electric potential of the intermittent KAW pulses, as is explained by Pierrard and Voitenko (2010) and demonstrated numerically by Li et al (2010). Simulation of this process requires a more complex modeling of the solar wind turbulence including intermittence.…”

“…Later on, at the Solar Wind 12 in June 2009, Pierrard and Voitenko have presented analytical estimations and numerical example, published in Pierrard and Voitenko (2010). Numerical simulations by Osmane et al (2010) and Li et al (2010) have demonstrated the proton beam formation by a coherent monochromatic KAW. Our present approach is based not on monochromatic KAWs but on a wide spectrum of KAWs with overlapping potentials, which results in the velocity-space proton diffusion rather than the proton trapping as in the mentioned above papers.…”

“…Kinetic models based on the solution of the Fokker-Planck equation have been developed to study the steady state electron velocity distribution function (VDF) in the corona and at larger radial distances in the solar wind (SW) (Lie-Svendsen et al, 1997;Pierrard et al, 1999;Lie-Svendsen and Leer, 2000;Pierrard et al, 2001;Vocks and Mann, 2003;Vocks and Mann, 2009). The test electrons were submitted to the influence of the external forces and to Coulomb collisions with background particles (Pierrard et al, 1999;Lie-Svendsen and Leer, 2000;Pierrard et al, 2001). Such models were solved numerically and emphasized the effects of Coulomb collisions compared to the results of purely exospheric models that considered only the external forces (Maksimovic et al, 1997;Lamy et al, 2003).…”

A Highly Sensitive Nonenzymatic Sensor Based on Fe2O3 Nanoparticle Coated ZnO Nanorods for Electrochemical Detection of Nitrite

“…Nonenzymatic nitrite sensors require a nanostructured material as a potential catalyst to modify the electrode surface and carry out the electrochemical response in the presence of nitrite; see Table 1 . Recently, Haldorai et al prepared cobalt oxide nanospindles‐decorated reduced graphene oxide (Co 3 O 4 ‐rGO) composite and utilized the drop‐cast method to modify glassy carbon electrode (GCE) for sensing (Co 3 O 4 ‐rGO/GCE) electrode fabrication .…”
