As metal nanostructures demonstrated extraordinary plasmon resonance, their optical characteristics have widely been investigated in photo-electronic applications. However, there has been no clear demonstration on the location effect of plasmonic metal layer within the photoanode on both optical characteristics and photovoltaic performances. In this research, the gold (Au) nano-islands (NIs) fi...

Thèse dirigée par Thierry DEUTSCH et codirigée par Damien CALISTE préparée au sein du CEA/INAC/SP2M/L SIM dans l'Ecole Doctorale de Physique des Materiuax Lacunes chargees, etude dans des nano-agregats de silicium Thèse soutenue publiquement le 6 Mars 2012, I do not put my faith in any new institutions, but in the individuals all over the world who think clearly, feel nobly and act rightly. The...

In this study, CoCrFeMnNiW medium-entropy alloy coating on Q235 was fabricated by plasma surfacing technology. The wear performance of the prepared one-layer and two-layer studied a friction abrasion tester. microstructure were researched optical microscope, nano-indentation test, SEM, hardness results show that is made up fusion zone, equiaxed dendrites near coarse columnar crystals, near-surf...

The study of surface morphology of Au deposited on mica is crucial for the fabrication of flat Au films for applications in biological, electronic, and optical devices. The understanding of the growth mechanisms of Au on mica allows to tune the process parameters to obtain ultra-flat film as suitable platform for anchoring self-assembling monolayers, molecules, nanotubes, and nanoparticles. Fur...

Hu antigen C (HuC) has three RNA-binding domains (RBDs). The N-terminal two, RBD1 and RBD2, are linked in tandem and bind to the AU-rich elements (AREs) in the 3'-untranslated region of particular mRNAs. The solution structures of HuC RBD1 and RBD2 were determined by NMR methods. The HuC RBD1 and RBD2 structures are quite similar to those of Sxl RBD1 and RBD2, respectively. The individual RBDs ...

The optical transmission and electric field distribution of plasmonic nanostructures dictate their performance in nano-optics and nano-biosensors. Here, we consider the use of hollow, five-pointed, star-shaped nanostructures made of Al, Ag, Au or Cu. We use simulations based on finite-difference time-domain and the discrete dipole approximation to identify the strongest plasmon resonan‐ ces in ...

HD 169142 is part of the class (pre-)transitional protoplanetary disks showing multiple carbon nanodust spectroscopic signatures (aromatic, aliphatic) dominating infrared spectrum. Precise constraints on spatial distribution and properties carbonaceous dust particles are essential to understanding physics disk. The disk seen almost face-on thus offers a unique opportunity study radial evolution...
