FMLs are considered by many industries, including the aerospace industry, due to their important advantages such as high strength, low weight, corrosion and moisture resistance, good fatigue properties, and so on. The purpose of the present study is to improve the mechanical properties of the panel through the addition of nanoscale by improving the structure of the FML. For this purpose, the pe...

In this paper, we have proposed a novel structure of the fabrication of a chalcogenide As2Se3 glass photonic crystal fiber (PCF) with increased core diameter. As comparision with the normal PCFs in which silica glass is used as core material, the proposed PCF has following feature; firstly we have used the chalcogenide As2Se3 glass as core material in which the first ring area contains no air h...

The aluminum coordination state in bismuth doped silica glass, which has new broad infrared emission at 1.3 lm regions, was investigated by using Al NMR, and it is demonstrated that 6-fold coordinated aluminum ions with corundum structure are dominant in bismuth doped silica glass until Bi2O3 concentrations of 1.0 mol% with Al2O3. The aluminum ion efficiently affects the creation of a Bi lumine...

When a liquid is supercooled towards the glass transition, its dynamics drastically slows down, whereas its static structure remains relatively unchanged. Finding a structural signature of the dynamic slowing down is a major challenge, yet it is often too subtle to be uncovered. Here we discover the structural signatures for both translational and rotational dynamics in monolayers of colloidal ...

The quantum random energy model provides a mean-field description of the equilibrium spin glass transition. We show that it further exhibits a many-body localization-delocalization (MBLD) transition when viewed as a closed quantum system. The mean-field structure of the model allows an analytically tractable description of the MBLD transition using the forward-scattering approximation and repli...

Traditionally, bioactive glasses have been used to fill and restore bone defects. More recently, this category of biomaterials has become an emerging research field for bone tissue engineering applications. Here, we review and discuss current knowledge on porous bone tissue engineering scaffolds on the basis of melt-derived bioactive silicate glass compositions and relevant composite structures...

Using a fluorescence recovery after photobleaching (FRAP) technique, we present measurements of probe diffusion in a colloidal glass-a Laponite suspension. By varying the probe size over 2 orders of magnitude, as well as the concentration of the colloidal glass, we evidence and quantify the deviations of the probe diffusivity from the bulk Stokes-Einstein expectations. These experiments suggest...

Dynamic heterogeneity in glass formers has been related to their static structure using the concept of dynamic propensity. We reexamine this relationship by analyzing dynamical fluctuations in two atomistic glass formers and two theoretical models. We introduce quantitative statistical indicators which show that the dynamics of individual particles cannot be predicted on the basis of the propen...

In this paper, we describe a new method based on aerosol-assisted vapor synthesis for making glass materials by pyrolysis of readily available silsesquioxanes CH3Si(OCH3)3 and CH3Si(OC2H5)3. Combined powder X-ray diffraction (XRD) and spectroscopic studies in the far infrared region (FIR) showed that under applied conditions the method yielded amorphous materials. Subsequent structural studies ...
