A Silicon Carbide Lollipop

Silicon Carbide is an inorganic material and non-oxide ceramics. Many of researches have been performed and continue for Silicon Carbide ceramic material due to having a range of properties for the advanced technological applications. Besides of chemical stability, thermal stability and thermal shock resistance of Silicon Carbide, mechanical properties such as hardness and wear resistance are excellent for many engineering purposes like filter and catalyst supports for elevated temperatures, seal pumps for automotive water pumps, heat exchangers, bearing and abrasion resistant components or composite materials in armor protection. Silicon Carbide usage in medicine is also important due to biocompatibility feature of Silicon Carbide. Therefore, Silicon Carbide has already been used in myocardial heart probes, bone prosthetics and coronary heart stents. Most of these applications, light weight, stiff and strong porous structure of Silicon Carbide are needed. One way to obtain light weight material is producing porous regions in the lattice which may lead to decrease in mechanical properties of products. A group of researchers in the Center for Advanced Structural Ceramics of United Kingdom studied two different processes based on water suspension and sintering techniques to obtain ultra-light SiC. They built strong, light weight SiC porous structure like as lollipop seen in SEM image. They said that Silicon Carbide with highly porous scaffolds can be used in thermal management, filter and catalyst supports designed to work at elevated temperatures or as ceramic reinforcement in the production of composites.

Carbon Nanotubes Specifications and Properties Carbon Nanotubes, simply CNTs, are allotropes of carbon with a round and hollow nanostructure. These barrel shaped carbon molecules have crucial properties, which are significant for nanotechnology, hardware, optics and other different fields of materials science and innovation. The carbon nanotube’s excellent quality as a strong and firm material laid the basis on many applications. Not to mention carbon nanotubes exceptional heat conductivity, electrical and mechanical properties, Carbon Nanotubes are used as additives to diverse auxiliary materials. In terms of rigidity and flexibility Carbon Nanotubes are the stiffest and strongest materials. These quality outcomes from the covalent sp2 bonds framed between the individual carbon molecules. Unlike Graphene , Carbon Nanotubes are either conductive or semiconducting along the tubular hub. Carbon Nanotubes also have absorption, fluorescence properties. Bulk Carbon nanotubes are util...

Hydroxyapatite Nanopowders and Their Applications

Hydroxyapatite, is a naturally occurring mineral form of calcium apatite with the formula Ca 5 (PO 4 ) 3 (OH). Pure hydroxyapatite powder is white. Naturally occurring apatites can, however, also have brown, yellow, or green colorations, comparable to the discolorations of dental fluorosis. Hydroxyapatite Nanopowder/Nanoparticles (50 nm, 99.95+%)  has been widely used as a biocompatible ceramic in many areas of medicine, but mainly for contact with bone tissue, due to its resemblance to mineral bone. In mammals, the skeleton presents a carbonated and partially substituted apatite, based on nanocrystal aggregates, and associated with collagen, building up 3-D structures present in various bone tissue conformations like trabecular or cancellous bone. There has been growing interest in developing bioactive synthetic ceramics that could closely mimic natural apatite characteristics. As mentioned before,  Hydroxyapatite Nanopowder  is the main inorganic constituent of bon...
