Nickel (III) Oxide Powder and Its Applications

Nickel(III) oxide is the inorganic compound with the chemical formula of Ni2O3. Sometimes nickel (III) oxide is referred as black nickel oxide.
Nickel (III) oxide powders can be used in various applications. Nickel (III) Oxide (Ni2O3) Powder (40 nm, 99.95+ %) is used in the manufacture of nickel salts, specialty ceramics, and nickel catalysts for example to enhance the activity of three-way catalysts containing rhodium, platinum, and palladium used in automobile exhaust control.
Let's look at one of the applications of nickel (III) oxide in more details. Nickel (III) Oxide Powder can be used for Cr(VI) ion removal at room temperature.The presence of various heavy metals like Cr(VI), As(III), U(VI) etc. in aquatic environments causes major concern for aquatic life and human health due to their severe toxicity. Cr(VI) exists in the effluents of various industries like electroplating, pigments etc. and is identified to be one of the most fatal species due to its carcinogenic effects on human beings and its abundance in drinking water. Out of two different forms of chromium, the hexavalent (Cr(VI)) and trivalent form (Cr (III)) in aqueous medium, Cr(III) precipitates in its hydroxide and oxide forms, therefore it doesn't migrate in the solution and is easily separable. On the other hand, Cr(VI) being highly soluble in water is observed to be highly toxic due to its high redox potential it and causes cancer, kidney damage, gastrointestinal disorders etc.
Till date, among different readily available methods like chemical precipitation, solvent extraction, membrane separation, ion exchange, adsorption etc. to remove Cr(VI), adsorption is found to be the most suited one that is being successfully used to remove from its respective aqueous solutions. The most commercially used material for this purpose is the activated carbon or mesoporous carbon due to their high surface porosity. Apart from them, bio-adsorbents are used as adsorbents in waste water treatment. However, they have weak mechanical strength, poor separation capacity and hence they are not very effective in this field.
Recently, alternative materials including various oxide based nanocomposites and nanostructures have been synthesized as potential adsorbent of heavy metal ions. Thus, with the advancement of technology, newer materials with improved adsorption capacities are being developed. One of these newer materials is Nickel (III) Oxide (Ni2O3) Powder. Since metal oxides are known to have high adsorption capacity of toxic metals in nanodimensions, nickel (III) oxide can be used for this purpose.

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...
