Nickel Foam for Battery Cathode Substrate

As the importance of lithium ion batteries increases, the different components are started to be used in them. One of the important materials that is in lithium ion batteries is current collectors. Current collectors are important because they have a role in electrochemical energy storage.
The important thing for a current collector is to keep their internal resistance low in order to improve the electrochemical properties of this kind of electrochemical energy storage systems. Also a good current collector must have high conductivity, chemical stability during electrolyte and the potential window and mechanical strength. According to the studies made in this field it has been proved that porous materials which can be used as current corrector give good results in lithium ion batteries.
One of the materials that can be used as current collector in lithium ion battery systems is nickel foam. Nickel Foam for Battery Cathode Substrate has low density and porous structure with typically 75–95% of the volume consisting of void spaces, which means that is a selectable material as current collector. Nickel foam can be used in many various functions in energy absorption and rechargeable battery applications. According to the studies where nickel foam used states that nickel foam is a good current collector in alkaline supercapacitors as long as we subtract the contribution from the nickel foam to get correct specific capacitances of the active material.
So we can say that nickel foam is a good material to be used as a current collector in lithium ion batteries with the properties of high conductivity and 3D interconnected structure.

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...

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...

New Way of Deaf-Mute Communication with 3D Graphene

Image retrieved from: http://blogs.rsc.org/cc/2016/09/01/3d-graphene-adds-dimension-to-deaf%E2%80%93mute-communication/ Chinese scientists have developed wearable electronic device with conductive 3D graphene structure to translate sign language into written text. This technology can be applied by injecting graphene ink from a syringe under printed electronic field. For medical field, such as adhesive patches which determine heart, brain signal and neural activity, wearable and bio-integrated medical devices are very important. Due to noticeable properties of cast graphene, for example a 2D honeycomb lattice, excellent mechanical and electrical behaviors, Graphene has an important material in warble technology. However, it is difficult to preserve advantages of Graphene material in a 3D material which has an information about forces from every angle. Yanlin Song  and co-workers at the University of the Chinese Academy of Sciences, Beijing, and Shenyang Jianzhu University...
