Photoisomerisation of trans-stilbene in solution may be directly assisted by solvent collisions
Photoisomerisation of trans-stilbene solution assisted solvent collisions Chemical Physics
2012/4/20
Gas phase thermal isomerization rates of trans-stilbene obey the Arrhenius law at T~300 K, indicating that intramolecular vibrational redistribution (IVR) is complete or not restrictive for the reacti...
Visualization of Spatial Distribution of γ-Aminobutyric Acid in Eggplant (Solanum melongena) by Matrix-assisted Laser Desorption/Ionization Imaging Mass Spectrometry
Visualization Spatial Distribution γ-Aminobutyric Acid
2010/9/14
We applied imaging mass spectrometry (IMS) to determine the spatial distribution of γ-aminobutyric acid (GABA). We found that GABA had a specific localization in seeds. We also visualized various biom...

Silver Ion-Assisted Ring Expansions in Different Solvent Systems
Carbene bicyclic compound ring opening ring expansion vinylic halide
2010/4/9
Several ring expansion products carrying vinylic bromo functionality were synthesized by opening of the geminal dibromobicyclo[n.1.0]alkanes ring. Dibromocarbene was formed from bromoform and potassiu...
CTAB-Assisted Hydrothermal Synthesis and Magnetic Characterization of NixCo1-xFe2O4 Nanoparticles (x = 0.0, 0.6, 1.0)
Magnetic materials Spinels XRD Coercivity Hydrothermal synthesis
2010/4/9
Nickel ferrite, NixCo1-xFe2O4, NPs (where x = 0.0, 0.6 and 1.0) were successfully synthesized by a rapid and reproducible CTAB-assisted hydrothermal route. The influence of different hydrolyzing agent...
