In this paper, we propose the analytical solution of nano-rod antennas utilizing a cylindrical harmonics expansion. By treating the metallic nano-rods as plasmonic cavities, we derive closed-form expressions for both the internal and the radiated fields, as well as the resonant condition and the radiation efficiency. With our theoretical model, we show that besides the plasmonic resonances, eff...

The number of commercially available injectable soft tissue fillers has increased dramatically over the past decade. In the United States, a variety of temporary fillers have received Food and Drug Administration (FDA) approval. However, at the present time, there are no permanent soft tissue injectable fillers available. This article will discuss the authors' experience with some of the more p...

Owing to its favorable impacts on the properties of materials, nanotechnology is rapidly growing. Adding nano particles to a material can significantly affect its mechanical and physical properties. In recent years, nanotechnology has been applied in the field of medical sciences in order to enhance the quality of treatment procedures. This technology can be used in various aspects of dentistry...

The first phase of this work aims to use the right additive nano-fillers choices, such as exfoliated Graphite (ExG), increasing mechanical, electrical, and thermal performances. In work, we are interested in quantifying effect particles' size on a polymer matrix's performance. For this, three sets polymers filled with Graphite, characterized by particle sizes, called meshes 50, 100, 150, were i...

The influence of titanium alloy (Ti–5Al–2.5Sn) and commercially pure (cpTi) as fillers on dissimilar pulsed tungsten inert gas weldments Ti–5Al–2.5Sn/cpTi was investigated in terms microstructure, mechanical/nano-mechanical properties, residual stresses. A partial martensitic transformation observed the for all welding conditions due to high heat input. microstructure evolved FZ/cpTi interfacia...

The base polymer properties have been developed experimentally by adding small amounts of different fillers but they are expensive to the polymer material. Thus, it has been investigated that the incorporation of cost-less nanoparticles like clay and fumed silica nanoparticles into low density polyethylene LDPE and high density polyethylene HDPE which controlled the breakdown strength and volta...

Strategies for bone tissue engineering and regeneration rely on bioactive scaffolds to mimic the natural extracellular matrix and act as templates onto which cells attach, multiply, migrate and function. Of particular interest are nanocomposites and organic-inorganic (O/I) hybrid biomaterials based on selective combinations of biodegradable polymers and bioactive inorganic materials. In this pa...

This study attempts to acoustically characterize the most common filled pause vocalizations (or vocalic fillers) in spontaneous speech in European Portuguese: the near-open central vowel [å] and the mid-central vowel [ə]. For this purpose we analyzed the spectral information of the vocalic fillers by estimating their first two formant frequencies as well as their duration properties. The vocali...
