• ., in the nanorod short axis, remains as before blue-shifted compared to the MC absorption band. The photochromic transition (from the black to the grey curve) leads to a decrease of the main peak amplitude and to a clear enlargement of its spectral width. Our previous study with nanocylinders [16

• sum of the contributions and the averaging of the extinction signal over a large number of particles increases the resonance’s FWHM. It is worth noting that our previous results on arrays of nanocylinders allowed us to observe two distinct peaks, probably because of the geometry deviations that are

• minimized for nanocylinders. Finally, Figure 2c shows the extinction spectra recorded on 70 nm wide and 110 nm long nanorods. The short axis resonance before and after the photochromic transition (blue curves) are identical to Figure 2a and 2b, but in this case, the long axis resonance in the SPY form

• dilute gas along arrays of randomly distributed, vertically aligned nanocylinders (nanotubes or nanowires) as opposed to gas diffusion in long pores, which is described by the well-known Knudsen theory. Analytical expressions for (i) the gas diffusion coefficient inside such arrays, (ii) the time between

• : dilute gas; gas transport; molecular diffusion; nanocylinders; random walk; Introduction Arrays of vertically aligned nanowires and nanotubes with high-aspect ratio composed of various materials have been widely used in science and industry. Arrays of silicon nanowires [1][2] and carbon nanotubes [3

The magnitude of the signal enhancement observed here is similar to the enhancement of 105 reported for BSA protein on gold nanocylinders [27]. The identification of the Raman
