Gallium arsenide is a semiconductor with excellent electronic properties. The morphology of gallium arsenide nanoparticles is gray cubic crystals. Gallium arsenide nanoparticles are graded as toxic and dangerous for the environment. To start off with the basics: gallium arsenide is composed of 2 base elements; gallium and arsenic. When these two individual elements bind together, they form the aforementioned compound, which displays many interesting characteristics. Gallium arsenide is a semiconductor with greater saturated electron velocity and electron mobility than that of silicon. A semiconductor is a material that has electrical conductivity between an insulator and […]

Polytetrafluoroethylene

Polytetrafluoroethylene Polytetrafluoroethylene (PTFE) is a synthetic fluoropolymer of tetrafluoroethylene. Being hydrophobic, non-wetting, high density and resistant to high temperatures, PTFE is an incredibly versatile material with a wide variety of applications, thought it’s perhaps best-known for its non-stick properties.

Having a molecular structure of only carbon and fluorine atoms – (CF2-CF2) n – POLYFLON PTFE Fine Powder possesses the lowest coefficient of friction and the most superior heat resistance, chemical resistance, electrical properties and non-sticking property of any plastics. PTFE Fine Powder readily absorbs organic solvents, resulting in the formation of a paste, it can be extruded easily. It is widely used […]

Quantum Dots Security Inks

Quantum Dots Security Inks Quantum Dots Security Inks: Quantum Dot Quantum Dot is the nanometer sized semiconductor crystal with specific optical properties originates from the phenomenon which can be explained by the quantum chemistry and quantum mechanics. They have generally size range of 2-10 nm and possess 10-50 atoms in each particle. Band gap can be modified by controlling the size of colloidal nanocrystal. Therefore, they exhibit specific luminescence emission light properties depending on the particle size. Quantum dot exhibits not only luminescence emission light wavelength modification and narrow spectral width but also have high quantum efficiency and absorb wide range of wavelength.

Shape Memory Fasteners

Shape Memory Fasteners Shape Memory Fasteners: Shape memory fastening technology uses the unique properties shape memory polymer (SMP) material. At a specific temperature, this material changes from a rigid state to an elastic state and then returns to a rigid “memorized” state again. When the rapid release system is activated, the fasteners become flexible, allowing simple, snap-on attachment. Once fastened, the system returns to a rigid state, locking the fasteners in place. To detach the fasteners again, the user simply activates the system, transitioning the material back to an elastic state, allowing easy removal. This process can be repeated over and over again. The material is simply activated by heat and reduces the labor and time needed to attach and […]

The reinforcing effect of mineral filler for polymers has been recognized after 1930s. Since the last three decades, improving the mechanical, electrical, thermal, optical and processing properties of polymer with […]

NanoTech Lubricants

NanoTech Lubricants NanoTech Lubricants: In the industry, most of the surfaces in mutual contact (i.e., bearings, seals and gears) are lubricated with specific oils in order to control friction and wear. Many scientific researchers have been published on the tribological properties of nanoparticles-based lubricants and the phenomena regarding any mechanical system in relation to friction and wear, strongly depends upon the characteristics of the nanoparticles, such as shape, size and concentration within the lubricant. Even a small concentration of nanoparticles (a few tenths of a percent by weight) could be sufficient to improve the tribological properties of the system. When the load between the sliding parts is small (low load conditions), friction reduction is mainly ascribable to the bearing-like behavior […]

Alloy Nanopowders

ALLOY NANOPOWDERS Alloy Nanopowders: In materials science, the range of properties of metallic systems can be greatly extended by taking mixtures of elements to generate intermetallic compounds and alloys. In many cases, there is an enhancement in specific properties upon alloying due to synergistic effects, and the rich diversity of compositions, structures, and properties of metallic alloys has led to widespread applications in electronics, engineering, and catalysis. The desire to fabricate materials with well-defined, controllable properties and structures on the nanometer scale coupled with the flexibility afforded by intermetallic materials has generated interest in bimetallic and trimetallic nanoclusters, which will be referred to as alloy nanoclusters or nanoalloys. As for bulk alloys, a very wide range of combinations and compositions […]
