Tyrosine nitration, often observed during neurodegenerative disorders under nitrative stress, is usually considered to be induced chemically either by nitric oxide and oxygen forming nitrogen dioxide or by the decomposition of peroxynitrite. It can also be ...
Triatomic transition-metal oxides in the "inserted dioxide" (O-M-O) structure represent one of the simplest examples of systems that undergo qualitative geometrical changes via subtle electronic-structure modulation. We consider here three transition-metal ...
In recent work, the authors have shown that d(AT)15 DNA-wrapped single-walled carbon nanotubes (SWNTs) are able to detect the adsorption and desorption of single mols. of nitric oxide (NO) from the surface by quenching of the near-IR fluorescence. A centra ...
We report the selective detection of single nitric oxide (NO) mols. using a specific DNA sequence of d(AT)15 oligonucleotides, adsorbed to an array of near-IR fluorescent semiconducting single-walled carbon nanotubes (AT15-SWNT). While SWNT suspended with ...
With different mass ratios, titanium dioxide/carbon nanotube (0.1-10 wt% CNTcontent) nanocomposites were prepared with the aid of ultrasonication method. The structures of the various TiO2/CNT nanocomposites were characterized by electron microscopy (scann ...
Iron containing ZSM-5 zeolites is extremely active in nitrous oxide decomposition. This reaction involves atomic oxygen species known as "alpha oxygen" on iron sites. Despite the multiple techniques devoted to its characterization, the active sites' struct ...
The chiral dissymmetric tetradentate ligand (S)-6′-(4-phenyloxazolin- 2-yl)-2,2′-bipyridine-6-carboxylate (S-Phbipox) leads to the diastereoselective assembly of a homochiral Eu3+ triangle and a highly emissive (quantum yield = 27%) heptanuclear wheel that ...
Embodiments include a vehicle for delivery of nitric oxide comprising: a collection of micelles having an internal micelle core that comprises a polymer with N-diazeniumdiolate comprising NO complexed with secondary amines of the polymer. Embodiments inclu ...
Electrochemical oxidation of ammonia (NH3 and NH4+) on boron-doped diamond (BDD) electrode was studied using differential electrochemical mass-spectrometry (DEMS) and chronoamperometry. Electro-oxidation of ammonia induces inhibition of the oxygen evolutio ...
Major explosive volcanic eruptions inject gases and ash particles into the stratosphere, resulting in significant impacts on ozone and climate. Here we report on fast and sensitive in situ measurements of sulfur dioxide (SO2), hydrochloric acid (HCl), and ...
