Creates CNTs through arc-vaporization of two carbon rods placed end to end, separated by few mm, in an enclosure that is usually filled with inert gas (Helium) at low pressure. A direct current of order of few hundreds Ampere (based on Graphite Current Density), driven by a potential difference of approximately 20 - 50 V, creates a high temperature discharge between the two electrodes. The discharge vaporizes the surface of one of the carbon electrodes, and forms a small rod-shaped deposit on the other electrode. High yield of CNTs depends on the uniformity of the plasma arc, and the temperature of the deposit forming on the carbon electrode.

The process of fluidization occurs when a fluid (liquid or gas) is passed up through the granular material under specified conditions. When a carbon containing gas flow is introduced through the bottom of a bed of solid catalyst particles, it will move upwards through the bed via the empty spaces between the particles The solid substrate (the catalytic material upon which chemical species react) material in the fluidized bed reactor is typically supported by a porous plate. The fluid (hydrocarbon and carrier gases) is then forced through the distributor up through the solid material. Depending on the operating conditions and properties of solid phase various flow regimes carbon nano-materials can be synthesized. Used for continuous synthesis of carbon nano-materials.

Ultrasonic soldering system combines heat and ultrasonic vibration to enable the soldering on glass, ceramics, aluminium, stainless steel and other unsolderable substrates. Solder is bonded to the substrate without using any chemical agents; hence the whole soldering process is flux free. The resulting joints have a high degree of electrical conductivity, adhesive strength, air/water tightness, weather and humidity resistance.

Details

Sputtering is a vacuum evaporation process which physically removes portions of a coating material called the target, and deposits thin, firmly bonded onto an adjacent surface called the substrate.

The process occurs by bombarding the surface of the sputtering target with gaseous ions under high voltage acceleration. As these ions collide with the target, atoms or occasionally entire molecules of the target material are ejected and propelled against the substrate, where they form a very tight bond. The resulting coating is held firmly to the surface by mechanical forces, although, in some cases, and alloy or chemical bond may result. Since the coating material is passed into the vapor phase by a mechanical rather than a chemical or thermal process, virtually any material can be deposited. Direct current is used to sputter conductive materials.

DC magnetron sputtering system can deposit catalyst particles like Iron, Nickel, Cobalt etc on substrate materials for the growth of carbon nanotubes.

Measures sample dimensional changes under conditions of controlled temperature, time, force, and atmosphere.

Offers all the major deformation modes necessary to characterize a wide range of materials such as solids, foams, films, and fibers. These include expansion, penetration, compression, tension, and 3-point bending.

Measures material deformation changes under controlled conditions of force, atmosphere, time and temperature. Force can be applied in compression, flexural, or tensile modes of deformation using specially designed probes.

Measures intrinsic material properties (e.g., expansion coefficient, glass transition, Young's modulus), plus processing/ product performance parameters (e.g., softening points).
