The spontaneous formation of self-assembled honeycomb-patterned structures from a single-walled carbon nanotube (SWNT) solution is shown. Simple casting SWNT–lipid conjugate (complex 1) on solid substrates used. Microporous films (see figure) are cast solutions the complex in various solvents.

The introduction of high-resolution CMOS image sensors (S. Yoshihara et al., 2006) has encouraged the development various applications to handle high frame rates, resolution, and multiple images processed by software. Complicated processing algorithms used in DSCs camcorders, which make use adaptive deal with characteristics scenes objects, require extensive computational power, as well low power consumption increased flexibility. FIESTA is developed adapt these markets.

These two processes formulated introduced into intranuclear cascade model. The calculated spectral shapes magnitudes double-differential cross sections agree well with all experimental observations over entire ranges emission energy laboratory angle. model reveals contributions knockout in terms incident-energy dependence. Direct accounts for highest domain...
The intranuclear cascade model is extended to cluster-induced (deuteron and alpha particle) nuclear reactions involving inelastic scattering breakup reactions. proposed explains the projectile process by describing cluster as a superposition of several states. incident produced are assumed be collections independent particles may undergo interaction through nucleon–nucleon with target nucleus. Trajectory deflections for ejecta incorporated in account angular distributions. Calculations...
Proton-induced nonelastic cross sections for $^{12}\mathrm{C}, ^{27}\mathrm{Al}, ^{56}\mathrm{Fe}$, and $^{208}\mathrm{Pb}$ are investigated in a low-energy region below 100 MeV down to nearly 0 based on framework of an intranuclear cascade (INC) model. We point out that there is scaling among the calculations including Coulomb repulsion; two cases shown: One trajectories with different impact parameters, other incident-energy dependence sections. first time calculated by usual INC model...
