Search Tips

This search combines search strings from the content search (i.e. "Full Text", "Author", "Title", "Abstract", or "Keywords") with "Article Type" and "Publication Date Range" using the AND operator.

Search Examples

aromatic	the word “aromatic”
aromatic aldehyde	the word “aromatic” OR “aldehyde”
+aromatic +aldehyde	both words “aromatic” AND “aldehyde”
+aromatic -aldehyde	the word “aromatic” but NOT “aldehyde”
“aromatic aldehyde”	the exact phrase “aromatic aldehyde”
benz*	words which begin with “benz”, such as “benzene” or “benzyl”
benz*yl	words that begin with “benz” and end with “yl”, such as “benzyl” or “benzoyl”
benzyl~	words that are close to the word “benzyl”, such as “benzoyl” (i.e., fuzzy search)

their structural defects [110]. The fuel cell [111], discovered in 1839 by Sir William Grove [112], is a device in which the production of electricity is due to oxidation on a fuel reducer electrode coupled to the reduction of an oxidant on the other electrode. The oxygen reduction reaction plays a key

nanostructure. It was reported that cathodic photocurrents were obtained at a nanocrystalline TiO2 film electrode due to oxygen reduction in alkaline solutions [7]. Visible light sensitization of TiO2 by surface complexation with [Fe(CN)6]4− has also been reported [8]. In such a case it was suggested that the
