We present a thorough analysis of one- and two-color transient absorption measurements performed on single- and double-walled semiconducting carbon nanotubes. By combining the currently existing models describing exciton-exciton annihilation-the coherent and the diffusion-limited ones-we are able to simultaneously reproduce excitation kinetics following both E11 and E22 pump conditions. Our sim...

For the single-walled carbon nanotubes, the higher values of anti-Stokes/Stokes Raman intensity ratio (Ias/Is) then the predictions of the Maxwell-Bolzmann formula indicates a CARS emission resulting from a wave mixing process between the incident laser light (ωl) and Stokes Raman light (ωs) generated by a SERS mechanism . The weaker value of (Ias/Is) observed at resonant excitation of semicond...

Emerging evidence supports that premature infants are susceptible to both cerebral white and gray matter injury. In a fetal rabbit model of placental insufficiency, preterm rabbits at embryonic day 22 (E22) exhibited histologic evidence of gray matter injury but minimal white matter injury after global hypoxia-ischemia (H-I). We hypothesized that the dissociation between susceptibility to gray ...

We have studied intersubband decay of E22 excitons in semiconducting carbon nanotubes experimentally and theoretically. Photoluminescence excitation line widths of semiconducting nanotubes with chiral indicess (n,m) can be mapped onto a connectivity grid with curves of constant (n - m) and (2n + m). Moreover, the global behavior of E22 line widths is best characterized by a strong increase with...

The purpose of the present study was to determine whether endogenous factor(s) contributes to the expression of heat shock proteins (HSPs) during the early developmental stages of rat skeletal muscles. HSP72 was expressed in both the soleus and plantaris muscles at embryonic day 22 (E22). On the basis of myosin heavy chain (MHC) immunohistochemistry, HSP72 was specifically expressed in slow typ...
