As the Ni composition, particle size and its homogeneous distribution in the SOFC anode of Ni-yttria stabilized zirconia (YSZ) composite are important factors in electrochemical performance, better control of the properties of NiO–YSZ nanocomposite

Spherical magnetite (Fe3O4) nanocrystal clusters (MNCs) were synthesized via reductive aging of ferric precursor (FeCl36 H2O) in ethylene glycol (EG) in the presence of potassium acetate (KOAc). EG was used both as a reducing agent and a solvent. The

We studied the growth of SnO2 nanocrystals with a tailored structure via surface capping assisted hydrothermal approach with tetramethyl ammonium hydroxide (N(CH3)4OH; TMAH). KOH and NaOH were also used instead of TMAH for comparison. The nanocrystal

In this study, we demonstrate for the first time the hydrothermal synthesis of yttria-stabilized zirconia (YSZ) nanocrystals with controlled yttria content (x = 3-12 mol %; xYSZ) with negligible aggregation from aqueous solution. The nanocrystals wer

Directed assembly of metal oxide nanoparticles with the aid of DNA was investigated. One-dimensional arrangement of zirconia (ZrO 2 ) nanoparticles using DNA as a template was shown by TEM observation. It is considered that the DNA-directed assembly

Bile acids are transformed by intestinal microflora. Secondary bile acids including deoxycholic acid and lithocholic acid appear to show a strong correlation with colorectal cancer. However, the role of intestinal bacteria in the transformation of bi

Germfree (GF) mice were orally inoculated with human fecal suspension or various components of human fecal microbiota. Three weeks after the inoculation, cecal bile acid composition of these mice was examined. More than 80% of total bile acids was de
