Copper Nanoparticles and Applications of Copper Nanopowders

Copper Nanoparticles and Applications of Copper Nanopowders
Information about Copper 
Copper is a chemical element with symbol Cu and atomic number 29. It is a soft, malleable, and ductile metal with very high thermal and electrical conductivity. A freshly exposed surface of pure copper has a reddish-orange color. Copper is used as a conductor of heat and electricity, as a building material, and as a constituent of various metal alloys, such as sterling silver used in jewelry, cupronickel used to make marine hardware and coins, and constantan used in strain gauges and thermocouples for temperature measurement.

Nanoparticles of Copper and Application Areas 
Copper Nanoparticles display unique characteristics including catalytic and antifungal/antibacterial activities that are not observed in commercial copper. Copper Nanoparticles demonstrate a very strong catalytic activity, a property that can be attributed to their large catalytic surface area. With the small size and great porosity, the nanoparticles can achieve a higher reaction yield and a shorter reaction time when utilized as reagents in organic and organometallic synthesis. Copper Nanoparticles with great catalytic activities can be applied to biosensors and electrochemical sensors. Redox reactions utilized in those sensors are generally irreversible and also require high overpotentials (more energy) to run. In fact, the nanoparticles have the ability to make the redox reactions reversible and to lower the overpotentials when applied to the sensors. Copper nanoparticles that are extremely small and have a high surface to volume ratio can also serve as antifungal/antibacterial agents. The antimicrobial activity is induced by their close interaction with microbial membranes and their metal ions released in solutions. Copper Nanopowders can be used as a replacement for more expensive metals, because Copper Nanopowders are ideal for reducing production costs, and find wide usage in microelectronic processes, conductive pastes, and as nanometal lubricant and sintering additives.

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...
