This study proposes a novel coating to enhance the reliability of electrical transmission systems. Environmental contamination of outdoor insulation surfaces leads to the puncture of insulators and heavy loss due to power outage in the transmission line. The water droplet on superhydrophobic coatings can pick up dirt particles and remove contamination from the surface of insulators due to the easy cleaning property of these coatings. Fabricated superhydrophobic coating in this paper has contact angles higher than 150° and CAH (Contact Angle Hysteresis) less than 10 degrees. This coating indicated good rubbing durability and there was not any contamination on the surface of coating after immersion in polluted water by Kaolin.

In this work, we have studied the optical properties of CdSe colloidal quantum dots (CQDs) that undergo a ligand exchange. The QDs were synthesized by the thermal decomposition method and characterized by using optical spectroscopy techniques and Density Functional Theory (DFT) calculations. Trioctylphosphine (TOP) and Oleic acid (OA) ligands were replaced by Formic acid. This ligand exchange seems to cause an increment of the Stokes shift on the nanostructures. As a result a surface underpassivation of the nanostructures appears. This could be related to the generation of non-radiative states that decreases the quantum yield in our samples and a redistribution of the band edge electronic states that explain to some extent our observed results.

The present paper deals with the analysis approach of multiconductor microstrip systems an integrated circuits using the finite element method (FEM). And we look for the best dimensions of the tracks for minimized the electromagnetic interaction in order to adapt them in microtechnology. Interconnects are multiple strip and multilevel in ICs. Today interconnects are great attention in high speed digital design and microwave integrated circuit application. With increased density of packing, line to line coupling of electromagnetic also becomes prominent. Computation of the matrices of capacitances, inductances per unit length of multiconductor is important since these elements are essential parameters in designing of package.

During last few decades the application of carbon nanotubes as an option of reinforcing element in nanocomposites, has become considerably popular, particularly in the aerospace and aeronautical industry. Nanocomposites are preferred over conventional materials because of their superior mechanical properties, such as high specific strength, high stiffness, low density and fatigue resistance. However, studies still need to be carried out, especially for dynamic response of the nanostructure and the reinforcement in the composite. Therefore, the objective of this work is to model a Single-Walled Carbon Nanotube (SWCN) as a space frame structure by using the modified Morse potential and as a thin shell based on Donnell’s theory to analyze its dynamic properties, in terms of its natural frequencies, under different types of boundaries conditions, and a Carbon-Nanotube-Reinforced-Polymer (CNRP) by developing a 3D multiscale finite-element model of the composite under the same boundary conditions. The natural frequencies of the SWCN obtained from the modified Morse potential are compared with the natural frequencies obtained from the shell theory, while the natural frequencies of the CNRP are compared with the natural frequencies of the polymer.
