Broad tuning

Synthesis of one dimensional, two dimensional and three dimensional nanostructured metal oxides have attracted a great deal of interest for the past many years. Because of their size dependent catalytic and optoelectronic properties, they can be broadly tuned through size variation. Recently, extensive efforts have been made to synthesize one dimensional metal oxides nanostructures such as nanowires, nanobelts, nanotubes, nanorods, nanorings etc [Fig.2], Various methods have been used in literature for development of nanostructured metal oxides of varying shape and sizes are as follows. 

A central question in bitter taste research is if bitter taste receptor cells are broadly tuned sensors for most, if not all, bitter tastants, or if bitter taste receptor cells are rather heterogeneous, thus providing a potential cellular basis for a discrimination...

Fig. 7.5 Physiological properties of dCRNs on the legs (in funnel-canal organs of the shore crab, C. maenas). Response spectra of 44 cells to stimulation with 19 single chemicals. Some dCRNs are broadly tuned but most are narrowly tuned with L-glutamate-best and taurine-best cells being most frequent. From Schmidt and Gnatzy 1989...
