Oleic acid capped monodisperse SnO(2) quantum dots (QDs) of size 2.7 nm were synthesized by thermal decomposition and oxidation of Sn(II)(oleate) complex in high boiling nonpolar solvent octadecene using oleic acid as a capping agent and N-methylmorpholine N-oxide as an oxidizing agent. FTIR, DSC and TGA were employed to understand the growth of the oleic acid capped SnO(2) QDs through the deco...

We describe the discovery of sno-lncRNAs, a class of nuclear-enriched intron-derived long noncoding RNAs (lncRNAs) that are processed on both ends by the snoRNA machinery. During exonucleolytic trimming, the sequences between the snoRNAs are not degraded, leading to the accumulation of lncRNAs flanked by snoRNA sequences but lacking 5' caps and 3' poly(A) tails. Such RNAs are widely expressed i...

SnO(2)/Sn nanocables have been grown on single-crystal Si substrates by metal catalyst assisted thermal evaporation of SnO powders. The morphologies and structures of the prepared nanocables were determined on the basis of field emission scanning electron microscopy (FESEM), high-resolution transmission electron microscopy (HRTEM), x-ray diffraction (XRD), Raman and photoluminescence (PL) spect...

Photoinduced interfacial electron transfer (IET) in sulforhodamine B (SRhB)-aminosilane-Tin oxide (SnO(2)) nanoparticle donor-bridge-acceptor complexes has been studied on a single molecule and ensemble average level. On both SnO(2) and ZrO(2), the sum of single molecule fluorescence decays agree with the ensemble average results, suggesting complete sampling of molecules under single molecule ...

This paper reports the improvement in the sensing performance of nanocrystalline SnO(2)-based liquid petroleum gas (LPG) sensors by doping with fluorine (F). Un-doped and F-doped tin oxide films were prepared on glass substrates by the dip-coating technique using a layer-by-layer deposition cycle (alternating between dip-coating a thin layer followed by a drying in air after each new layer). Th...

Coenzyme A (CoA) mediates thiol-based acyl-group transfer (acetylation and palmitoylation). However, a role for CoA in the thiol-based transfer of NO groups (S-nitrosylation) has not been considered. Here we describe protein S-nitrosylation in yeast (heretofore unknown) that is mediated by S-nitroso-CoA (SNO-CoA). We identify a specific SNO-CoA reductase encoded by the alcohol dehydrogenase 6 (...

The interaction in the system of SnO2 and h-MoO3 prepared by their joint mechanical activation in a roller-ring vibratory mill was investigated. A series of catalysts was prepared with SnO2: h-MoO3 molar ratio 1:1; 1:2.3; 2.3:1 and 5.7:1. The catalysts were characterized by various techniques including X-ray phase, X-ray diffraction (XRD) and synchron...

CNT/Au/SnO(2) nanotubes have been synthesized through homogeneous coating of Au and SnO(2) nanocrystals on carbon nanotubes (CNTs) and applied in a room-temperature CO gas sensor.

In this paper, the effects of changes in Sol concentration on the structural and optical properties of SnO2 Nanoparticles are studied through the Sol-Gel method. SnO2 Nanoparticles are produced from different SnO2 solution concentrations (0.1, 0.3 and 0.5 mol/L) at room temperature.  X-Ray Diffraction (XRD) and Scanning Electron Microscopy (SEM) analysis are...

The third and final phase of the Sudbury Neutrino Observatory (SNO) experiment utilized a series of He proportional counters called Neutral Current Detectors (NCDs) to detect the neutrons produced by the neutral current interactions of solar neutrinos in the detector. The number of neutrons detected by the NCDs, and hence the total flux of B solar neutrinos, has been determined using two novel ...
