Reactive oxygen species' role in endothelial dysfunction by electron paramagnetic resonance
endothelial dysfunction ex vivo spin trapping porcine tissue
2015/1/19
The endothelium is a single layer of cells lining the arteries and is involved in many physiological reactions which are responsible for vascular tone. Free radicals are important participants in thes...
Effects of temperature and irradiance on a benthic microalgal community: A combined two-dimensional oxygen and fluorescence imaging approach
benthic Two-dimensional oxygen fluorescence
2014/10/16
The effects of temperature and light on both oxygen (O2) production and gross photosynthesis were resolved in
a benthic microalgal community by combining two-dimensional (2D) imaging of O2 and variab...
First-principles study on the magnetic properties in Mg dooped BiFeO3 with and without oxygen vacancies
Vacancies Magnesium Magnetic moments Antiferromagnetism Band gap
2016/12/2
The magnetic properties of Mg-doped BiFeO3 (BFO) with and without oxygen vacancies are studied through first-principles calculations. The Mg-doping prefers to occupy the ferromagnetic planes and produ...
Atmospheric Oxygen Binding and Hole Doping in Deformed Graphene on a SiO2 Substrate
graphene Raman spectroscopy scanning tunneling microscopy (STM)
2010/11/22
Using micro-Raman spectroscopy and scanning tunneling microscopy, we study the relationship between structural distortion and electrical hole doping of graphene on a silicon dioxide substrate. The obs...
Effect of oxygen plasma etching on graphene studied with Raman spectroscopy and electronic transport
Effect of oxygen plasma Raman spectroscopy electronic transport
2010/11/17
We report a study of graphene and graphene field effect devices after exposure to a series of short pulses of oxygen plasma. We present data from Raman spectroscopy, back-gated field-effect and magnet...
Pt-Decorated PdCo@Pd/C Core-Shell Nanoparticles with Enhanced Stability and Electrocatalytic Activity for Oxygen Reduction Reaction
Core-Shell Nanoparticles Enhanced Stability Electrocatalytic Activity Oxygen Reduction Reaction
2010/11/25
The high cost and scarcity of Pt pose serious problems for the widespread commercialization of fuel cell technologics.1 Recently, Pd-based cathode catalysts have attracted much attention because Pd po...
Critical-doping universality for cuprate superconductors: Oxygen nuclear-magnetic-resonance investigation of Ca(x)La(1-x)Ba(1.75-x)La(0.25+x)Cu(3)O(y)
cuprate superconductors Oxygen nuclear-magnetic-resonance investigation
2010/11/18
The critical doping levels in cuprates, where the ground state changes its nature (from an an-
tiferromagnet to a spin glass to superconductor to metal), are not universal. We investigate the origin ...
Absorption Line Profile of the 5S2o-5P1 Transition of Atomic Oxygen and Its Application to Plasma Monitoring
Line Profile Atomic Oxygen 5S2o-5P1 Transition
2009/9/4
The line profile of the 5S2o-5P1 transition of atomic oxygen was measured by diode laser absorption spectroscopy. As a result, it was found that the absorption line profile had a wing component in the...

Oxygen Ion Implantation in Strontium Bismuth Tantalate Thin Films
Ferroelectric Thin films SBT Oxygen implantation Plasma focus
2010/9/29
Strontium Bismuth Tantalate (SBT) ferroelectric thin films have attracted considerable attention for the development of non-volatile ferroelectric random access memories (NV-FRAMs). These films, howev...
Effect of Air-Oxygen and Argon-Oxygen Mixtures on Dielectric Barrier Discharge Decomposition of Toluene
Air-Oxygen and Argon-Oxygen Mixtures Dielectric Barrier Discharge Toluene
2010/10/27
One alternative application in the decomposition and destruction of volatile organic compounds (VOCs) by a silent plasma dielectric barrier discharge (DBD) has been successfully accomplished. For this...
Abrasion-ablation models and the empirical EPAX parametrization of projectile fragmentation are described. Their cross section predictions are compared to recent data of the fragmentation of secondary...
Effect of the Oxygen/Halogen Ratio on the Physical Properties of Some Sodium-Boro-Vanadate Glasses
Physical Properties of glass Glass containing halogen ions Glass structure
2010/4/13
Four different glass systems of the sodium boro-vanadate type containing halogen ions, were prepared by melting at 1000°C for three hours and annealed at 300°C. These glasses were investigated using d...
Energetic Oxygen Ions of Ionospheric Origin Observed in the Cusp
