Low temperature co-fired ceramic (LTCC) with silver and gold conductor systems offer a low cost, high performance, and high reliability solution utilizing the advantages of ceramic technology. Gold conductors are generally used in applications requiring best reliability in harsh environmental conditions. Gold conductors are bonded to active or passive components through wirebonding, soldering, ...

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...

Technological development in latent heat storage (LHS) systems is essential for energy security and management both renewable non-renewable sources. In this article, numerical analyses on a shell-and-tube-based LHS system with coupled thermal enhancement through extended fins nano-additives are conducted to propose optimal combinations guaranteed higher discharging rate, enthalpy capacity distr...

In this study, magnesium composites with nano-size boron nitride (BN) particulates of varying contents were synthesized using the powder metallurgy (PM) technique incorporating microwave-assisted two-directional sintering followed by hot extrusion. The effect of nano-BN addition on the microstructural and the mechanical behavior of the developed Mg/BN composites were studied in comparison with ...

Over the past two decades several nano-structuring methods have helped improve the figure of merit (ZT) in the state-of-the art bulk thermoelectric materials. While these methods could enhance the thermoelectric performance of p-type Bi2Te3, it was frustrating to researchers that they proved ineffective for n-type Bi2Te3 due to the inevitable deterioration of its thermoelectric properties in th...

Graphene is a novel material and currently popular as an enabler for the next-generation nanocomposites. Here, we report the use of graphene to improve the mechanical properties of nano-58S bioactive glass for bone repair and regeneration. And the composite scaffolds were fabricated by a homemade selective laser sintering system. Qualitative and quantitative analysis demonstrated the successful...

Calcium phosphate (CP) materials have been used extensively for bone replacement and augmentation due to their similarity to the mineral component of bone. In addition to being nontoxic, they are biocompatible, not recognized as foreign materials in vivo, and most importantly, exhibit osteoconductive behavior, being able to help in bone formation during healing. CPs form an intimate physicochem...

We report here experimental results of yield strength and stress relaxation measurements of transparent MgAl2O4 nano-ceramics at high pressure and temperature. During compression at ambient temperature, the differential strain deduced from peak broadening increased significantly with pressure up to 2 GPa, with no clear indication of strain saturation. However, by then, warming the sample above ...

This paper presents initial development of polymer nanocomposites (PNC) material for rapid manufacturing (RM) application. PNC materials containing a polyamide (PA) and nano particles (5wt%) were produced by solution blending with the aim to improve the mechanical properties. Commercial polyamide 6 (PA6) was dissolved in formic acid (HCO2H) together with two different types of nano particle mat...
