Monodisperse tetragonal SnO nanoparticles with exposed {100}, {010} and {001} facets have been successfully synthesized by decomposition of tin(ii) oxalate using 1-octylamine and oleic acid (OA). The percentage of exposed facets could be regulated by changing the proportion of 1-octylamine and OA. Based on the lithium-ion battery performance and structure analysis, we conclude that the monodisperse SnO nanoparticles with a greater percentage of exposed {010} and {100} facets exhibit a better electrochemical performance than those with exposed {001} facets.

Monodisperse single-crystal hollow cerium dioxide nanocubes with exposed (001) facets have been synthesized with the assistance of ammonium chloride (NH4Cl) and polyvinylpyrrolidone (PVP) in a water and ethanol system. A series of experiments indicate that ammonium ion plays an important role in the formation of the hollow structure and PVP plays a key role in the formation of a cubic shape. The hollow cerium dioxide nanocubes exhibit excellent CO catalytic oxidation activity. © 2013 The Royal Society of Chemistry. Source

Cardiolipin is a mitochondria-specific phospholipid known to be intimately involved with numerous mitochondrial functions. Accordingly, quantitative determination of cardiolipin provides a valuable aspect for assessing mitochondrial content and function. The current study was undertaken to develop a simple and reliable method for direct analysis of cardiolipin with particular application for the assessment of mitochondrial number of HepG2 cells. The method presented is based on the online 10-N-nonyl acridine orange (NAO) interaction with cardiolipin using CE with LIF detection. An aqueous-organic solvent system composed of 10% H 2O-40% methanol-50% ACN (all v/v) containing 20μM NAO provides both short analysis time within 2min and a definite fluorescence enhancement at 525nm for NAO-cardiolipin complex as compared with NAO alone. Under the optimum condition, a calibration curve between the peak area and the concentration of cardiolipin was established in the range of 0.1-200μM with a correlation coefficient of 0.9955. The detection limit is 9nM. The proposed method was successfully applied to the analysis of cardiolipin in mitochondria from HepG2 cells. A new biochemical method estimating the mitochondrial number per cell was developed and used together with the proposed method for cardiolipin per cell measurement and cardiolipin per mitochondrion reported before. © 2011 WILEY-VCH Verlag GmbH & Co.

An efficient and facile synthesis of 4,6-diarylpyrimidin-2(1H)-one via a Biginelli-like reaction of aromatic aldehydes, aromatic ketones, and urea in the presence of NaOH under solvent-free conditions using a heating method has been developed. Compared with the classical reaction conditions, this new synthetic method has the advantages of excellent yields, shorter reaction time, and mild reaction conditions.
