  • Bismuth oxide is a well known transition metal oxide and it intensively studies due to the thermal and electrical transport properties.
  • Bismuth oxide as a component finds use in wide applications in varistors, catalyst and gas sensors. Bi2O3 exhibits the highest ion conductivity of all oxide ion conductors. Bi2O3 is an advanced functional material with potential applications such as functional electronic material, burning rate catalyst, photocatalytic decomposition material, optical material, medical composite material and anti-radiative material. Bi2O3 is also used as an additive in paints Among various applications, Bismuth oxide (Bi2O3) arouses increasing attentions as a photocatalyst over the last few years.
Bismuth oxide can be different forms such as bismuth oxide nanoparticles, bismuth oxide nanostructures and bismuth oxide thin films. Bismuth oxide nanoparticles appear as yellow powder, and are graded as an irritant and might cause skin, eye, and respiratory irritations.
Production of Bismuth Oxide Nanoparticles:
Bismuth oxide nanoparticles can easily synthesize from a solution of bismuth nitrate pentahydrate (Bi(NO3)35H2O) in ethylene glycol by a hydrolysis solvothermal route at temperatures of 120-1500C. Bi2O3 nanoparticles will be the cubic phase structure.
Characterization of Bismuth oxide nanoparticles
X-ray diffraction, scanning electron microscopy and UV-visible diffuse reflectance spectroscopy can be used to characterize the Bismuth oxide nanoparticles

Usage of Silver Conductive Adhesive Paste in Corrosion Protection

In electronics, solders are main material to connect electrical components to substrates which are generally printed circuit boards. Although they are cheap, they are not effective if long term performance is considered since solders have low resistivity to corrosion relatively. Since corrosion reduce reliability, the cost of advanced technological systems such as RADAR, SONAR, LIDAR and more increase. In addition, small signals can be lost, and in huge data transfer, some of the data can be lost also especially which may lead catastrophic failures in critical systems. For instance, surface to air missiles can be launched to target which is not exist if the data coming from detection systems is noisy. Therefore, corrosion protection is necessary, and  silver conductive adhesive paste  is an essential candidate to replace PbSn solders due to its resistivity to corrosion. Silver conductive adhesive paste provide not only noisy reduction but also electromagnetic interference whi...

Titanium Carbide Powders and Applications

Titanium carbide which has the chemical formula of TiC attracted great interest for many structural applications due to its extremely high melting temperature, high hardness, high chemical resistance and good electrical conductivity. Therefore titanium carbide can be used in cutting tools, grinding wheels, wear-resistant coatings, high temperature heat exchangers, magnetic recording heads, turbine engine seals, and bullet-proof vests, etc. In addition, a promising field of application comprises plasma and flame spraying processes in air, where titanium carbide-based powders show high-phase stability. TiC(Titanium Carbide Powder) (325 mesh, 99,9+%)  can also be used in biomedical implant devices. Materials used for biomedical implant devices must satisfy a variety of property demands, which are often mutually exclusive. Further, different parts of a device demand different material properties. These factors often make it difficult to manufacture a medical device using a...

Nanocellulose: Descriptions, Usage and Applications

Nanocellulose  is denoted by nano-structured cellulose which consist of C6H10O5. Since cellulose is abundant polymer in nature, large quantity of nanocellulose can be manufactured from the cost-effective aspect. Non-toxic and lightweight properties make it easy to carry, so it can be used in applications which requires mobility. High tensile, stiffness and electrical conductivity expand its usage through electrical and mechanical applications. Unique properties depending on the type of nanocellulose are also exist. There are three types which are cellulose nanocrystal (CNC), cellulose nanofibers (CNF), and bacterial nanocellulose (BNC). First type of nanocellulose is  cellulose nanocrystal , development in applications show that CNCs have unique specialities for improving mechanical properties of nanocomposites such as electrospun nanocomposite fibers/mats and nanocomposite hydrogels. Numerous nanocomposite hydrogels reinforced with CNCs can be designed to be sens...
