sno nanoparticles were synthesized using microwave–assisted hydrothermal method. it was noticed that at 300 and 600 watt microwave power, sno formed and remained in the tetragonal phase. at 900 watt, sno2 started appearing and a mixture of sno and sno2 phases coexisted. the particle size varied from ~2 to ~13 nm at 300 to 900 watt radiation power. the uv-v absorption spectra showed the excitoni...

S-nitrosylation (SNO) is a reversible protein modification that has the ability to alter the activity of target proteins. However, only a small number of SNO proteins have been found in the myocardium, and even fewer specific sites of SNO have been identified. Therefore, this study aims to characterize potential SNO sites in the myocardium. We utilized a modified version of the SNO-resin-assist...

RATIONALE S-nitrosylation (SNO) is a reversible, thiol-based protein modification that plays an important role in the myocardium by protecting critical cysteine residues from oxidation. However, little is known with regard to the percentage of a given protein that is modified by SNO (ie, SNO occupancy). Current methods allow for the relative quantification of SNO levels, but not for the determi...

The sensing behavior of SnO(2)-based thick film gas sensors in a flow system in the presence of a very low concentration (ppb level) of chemical agent simulants such as acetonitrile, dipropylene glycol methyl ether (DPGME), dimethyl methylphosphonate (DMMP), and dichloromethane (DCM) was investigated. Commercial SnO(2) [SnO(2)(C)] and nano-SnO(2) prepared by the precipitation method [SnO(2)(P)]...

The novel SnO diskettes have been synthesized by evaporating either SnO or SnO(2) powders at elevated temperature. Disregard the source material being SnO or SnO(2), the SnO diskettes are formed at a low-temperature region of 200-400 degrees C. Two types of diskette shapes have been identified: the solid-wheel shape with a drop center rim (type I) and the diskette with cone peak(s) and spiral s...

Mitochondrial proteins have been shown to be common targets of S-nitrosylation (SNO), but the existence of a mitochondrial source of nitric oxide remains controversial. SNO is a nitric oxide-dependent thiol modification that can regulate protein function. Interestingly, trans-S-nitrosylation represents a potential pathway for the import of SNO into the mitochondria. The glycolytic enzyme glycer...

Snitrosylation (SNO) is a reversible, thiolbased modification that can modulate the activity of myocardial proteins, including those involved with Ca-handling and mitochondrial energetics. Additionally, we and others demonstrated that SNO can protect against cysteine oxidation. This is important in the setting of ischemia–reperfusion (IR) injury, in which the burst of reactive oxygen species ge...

(a group within the SNO collaboration studying this option for the future use of SNO, on behalf of the whole collaboration. This proposal has not been officially approved by the SNO collaboration as the defined future configuration for SNO and, if pursued, would undoubtedly involve the establishment of a new collaboration with additional participants as well as a subset of the members of the pr...

This paper demonstrates an acetylene gas sensor based on an Ag-decorated tin dioxide/reduced graphene oxide (Ag-SnO₂/rGO) nanocomposite film, prepared by layer-by-layer (LbL) self-assembly technology. The as-prepared Ag-SnO₂/rGO nanocomposite was characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD) and Raman spectrum. The acetylene...

Esterification reactions of some polyols and diols were investigated in the presence of SnO2 and nano-SnO2 and the results were compared with the catalyst-free conditions. High conversions were obtained for most of the reactions in the presence of SnO2 and nano-SnO2 which shows the high catalytic activity of SnO2 and nano-SnO2</sub...
