Graphene Battery

Batteries have become an important part in our electricity dependent modern lives. Every electronic device ranging from cell phones to computers rely on batteries for electricity storage. Even automobiles sector is shifting toward electric vehicles as the oil depletion and the environmental issues increase. The need for better battery with higher capacity, more stability and faster charging rates is in continuous demand. The solution is definitely in the development of new materials that have excellent properties which can increase the performance of the batteries. Graphene represent one of the best materials with extraordinary properties for the development of the batteries.

Graphene has very high surface area, hundred times better conductivity than copper and show good flexibility properties. Making battery out of graphene is one of the choices that battery developments have been working on. So far, hundreds of researches have been done that show the increase of the capacity, stability and charging rates of the graphene embedded batteries. Commercially, a Chinese company named Gongxu optoelectronics announced the first graphene battery with 4,800 mAh capacity and can be recharged in 13-15 minutes. Another company from Spain called Graphenano claims that they will produce graphene polymer cells that have 1,000 watt-hours per kilogram which is five times that of current lithium-ion cells. These developments show the importance of implanting nanomaterials such as graphene in different applications which can lead to excellent improvements in our daily lives.

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...

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...

Carbon Nanotubes Doped with Graphene Nanopowder and Applications

Carbon nanotubes and graphene are different forms of carbon atom based materials. They have different properties and can be used in various applications. But what happens if we use them as a hybrid structure? The excellent mechanical, physical, and chemical properties of low-dimensional carbon materials like graphene and carbon nanotube have enabled them as promising building blocks for three-dimensional nanoarchitectures. In this regard, extensive interests have been attracted to synthesize graphene and carbon nanotube hybrid structures. Earlier works suggested that  Carbon Nanotubes Doped with Graphene Nanopowder (52 wt% Graphene )  is a promising solution for quick energy dissipation, which could enhance interface thermal conductivity of the ‘building blocks’ for future nanoscale mechanical and electrical devices. In the electricity perspective, it is found that ‘CNT pillared-graphene’ system would extend the excellent electrical conductivity of graphene and nanotube to ...
