Abstract In engineering—especially in mechanics, lightweight engineering, aerospace electrical engineering as well bioengineering—there is a desire of developing materials enabling an excellent performance with respect to mechanical, thermal, and properties. One the most promising are carbon nanotubes (CNTs), they show mechanical To improve understanding behavior, i.e., charge distribution sing...

The properties of few layer (one layer (1 L) to four layer (4 L)) graphenes doped by adsorption and intercalation of Br(2) and I(2) vapors are investigated. The Raman spectra of the graphene G vibrations are observed as a function of the number of layers. There is no evidence for chemical reaction disrupting the basal plane pi electron conjugation. Adsorption of bromine on 1 L graphene creates ...

In this work we present a computational approach to the design of nanostructures made of structural motifs taken from left-handed beta-helical proteins. Previously, we suggested a structural model based on the self-assembly of motifs taken from Escherichia coli galactoside acetyltransferase (Protein Data Bank 1krr, chain A, residues 131-165, denoted krr1), which produced a very stable nanotube ...

This work gives sequence to the study on the measurement of the electrostatic charges in aerosols. The particle charge classifier developed for this purpose and presented in the previous paper (Marra and Coury, 2000) has been used here to measure the particle charge distribution of a number of different aerosols. The charges acquired by the particles were naturally derived from the aerosol gene...

This doctoral thesis reports analytical and numerical results for the electrostatic response of a dusty plasma to a moving test charge. Two important physical aspects of dusty plasmas, namely grain size distribution and grain charging dynamics were taken into account. In the first case, a dusty plasma in thermal equilibrium and with a distribution of grain sizes is considered. A size distributi...

The calculations of the charge distribution in the C60-based FET structure are presented. A simple model is proposed to describe the distribution of injected electrons or holes between two-dimensional layers. The calculations show that the relative layer charges are independent on the total amount of injected charges. The charge density is maximal on the surface layer and drops exponentially wi...
