Gallium Arsenide Nanoparticles

Gallium Arsenide Nanoparticles



Gallium Arsenide Nanoparticles: Nanoparticles research is currently one of the most active branches of science with many of applications in various fields. 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.

Gallium Arsenide Nanoparticles

Gallium Arsenide Nanoparticles

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 a conductor; it may vary its ability to conduct electricity when it is cool versus when it is hot. This makes it very useful in many applications. Another novel quality to gallium arsenide is that it has a direct band gap. This is a quality that denotes a compound that can emit light efficiently.

Gallium Arsenide Nanoparticles

GaAs is an important semiconductor that finds applications in the electronic industry especially in optoelectronic devices and solar cells. GaAs thin films were originally synthesized by the metal–organic chemical vapor deposition (MOCVD) method.

Properties of Gallium Arsenide NPs:

• Carrier density:

The low intrinsic carrier density of GaAs in a pure (undoped) form indicates that GaAs is intrinsically a very poor conductor and is commonly referred to as being semi-insulating. This property is usually altered by adding dopants of either the p- (positive) or n- (negative) type. This semi-insulating property allows many active devices to be grown on a single substrate, where the semi-insulating GaAs provides the electrical isolation of each device; an important feature in the miniaturization of electronic circuitry, i.e., VLSI (very-large-scale-integration) involving over 100,000 components per chip (one chip is typically between 1 and 10 mm square).

• Electron mobility:

The higher electron mobility in GaAs than in Si potentially means that in devices where electron transit time is the critical performance parameter, GaAs devices will operate with higher response times than equivalent Si devices. However, the fact that hole mobility is similar for both GaAs and Si means that devices relying on cooperative electron and hole movement, or hole movement alone, show no improvement in response time when GaAs based.

Applications of Gallium arsenide NPs:

Gallium arsenide NPs is used in the manufacture of light-emitting diode s (LEDs), which are found in optical communications and control systems. Gallium arsenide can replace silicon in the manufacture of linear ICs and digital ICs. Linear (also called analog) devices include oscillator s and amplifier s. Digital devices are used for electronic switching, and also in computer systems.

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.

Polytetrafluoroethylene

Polytetrafluoroethylene

PTFE Fine Powder is a milky white polymer which is separated from a dispersion formed by emulsion polymerization. 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 for the manufacture of insulated electric wires, spaghetti tubes, thin rods and unsintered tape.

Polytetrafluoroethylene

Polytetrafluoroethylene

Properties of PTFE

Thermal Properties: PTFE can be used continuously at temperature up to 260° (500°F), and for short periods at even higher temperatures. It also possesses excellent low temperature strength. With these superior thermal properties, products such as electric or electronic machinery components, pipe linings, insulated electric wires, etc., made with PTFE Fine Powder are widely used.

Chemical properties: PTFE possesses the excellent property of almost absolute resistance to all commonly used chemicals. When used with some special chemicals under extremely severe conditions, such as fused alkali metals, high-temperature, high-pressure fluorine or trichlorofluorine gas, slight changes may occur. With ordinary acids, alkalis, and oxidants at high temperatures PTFE remains completely stable. Even contact with organic compounds does not cause dissolution or swelling. The basic reason for PTFE‘s extensive use in the chemical industry for pipe linings, wire-braid hoses, gaskets, tubes and bellows is in its chemical inertness.

Low abrasion and non-sticking property: Under ordinary conditions of use, PTFE possesses the lowest coefficient of friction of any solids. Moreover, its remarkable non-sticking property prevents most adhesive materials from adhering to it. Tubes made of PTFE Fine Powder are therefore used as transport tubes for liquid adhesives, cableway pipes, etc., for automobile and other mechanical industries, and other similar applications. In addition, unsintered tape made of PTFE Fine Powder, being extremely soft and malleable, forms tightly to the threads of bolts to provide an excellent sealing effect.

Applications of PTFE

PTFE is used extensively in many different industries:

Petrochemical and chemical processing: PTFE is the material of choice for gaskets, vessel linings, pump interiors, washers, rings, seals, spacers, dip tubes and well-drilling components because it is corrosion resistant and chemically inert; it is unaffected by virtually all acids and caustics and functions in environments to 500 degrees F.

Electrical applications: PTFE is one of the best insulators known. In thin sections, it will insulate to 500 volts per mil. There are grades of PTFE which have even greater dielectric strength. It is frequently used in wire and cable wrap, and to separate conductive surfaces in capacitors. Thick walled close-tolerance extruded tubing is the PTFE shape of choice where machining or drilling long lengths to close tolerances is impossible. Multi-hole tubing can be extruded. PTFE can be machined into standoff insulators, and many different types of high voltage encapsulation devices for electrical components.

Polytetrafluoroethylene

Electrical applications

Semi-Conductor Industry: PTFE is inert, and its operating temperature range is from minus 350 degrees Fahrenheit to 550 degrees Fahrenheit. When made to ultra pure standards it is the material of choice for various items used in chip manufacturing, including encapsulation devices for quartz heaters and many more.

Food, Beverage and Pharmaceutical industries: PTFE is approved by the Food and Drug Administration for use in the food, beverage, cosmetics and pharmaceutical industries. Thin Film and sheets make an inert, no-toxic slide surface without microscopic depressions where microbes can grow.

Polytetrafluoroethylene

Food, Beverage and Pharmaceutical industries

Laboratory applications: PTFE piping, tubing and vessels are used in various laboratory wares because of their chemical resistance, and inertness. No contaminants adhere to the surface.

Polytetrafluoroethylene

Laboratory applications

Bearing pads: Glass filled PTFE can be cut or stamped into bearing pads, and will resist all weather-related degradation while remaining an inert interface between disparate construction materials, like steel and concrete.

PTFE Compounds: Various fillers can be blended with the PTFE base resin to enhance certain properties, e.g. glass fiber, glass bead, carbon, graphite, molybdenum disulfide, bronze, etc.

PTFE does not melt; it cannot be molded into complex shapes, but must be machined. PTFE is easily machined using standard mechanical woodworking and stamping equipment and tooling. Most shapes are sold slightly oversized for easy trimming and machining to exact sizes.

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.

Quantum Dots Security Inks

Quantum Dots Security Inks

The concept of energy level, band gap, conduction band, valence band can be applied to normal bulk sized semiconductor except one clear difference. In bulk status, the particle size of semiconductor is much larger than Exciton Bohr Radius and exciton can be reached to nature limit. On the other hand, when the particle size of semiconductor becomes closed the size of Excition Bohr Radius, electron energy level losses its continuity and becomes separate, namely small separation can be observed among energy level. This separated energy status is called quantum confinement and semiconductor materials become no longer bulk status but “quantum dot” status. In this situation, absorbance and light emission properties of semiconductor material is different.

In quantum dot status, electron moves between the edge of band gap just like in bulk semiconductor status. In quantum dot status, luminescence emission light wavelength can be easily precisely modified by changing the particle size, by modifying the band gap size since emission light wavelength depends on the band gap energy. In our technology, basically, quantum dot can be dispersed in solution (water, various type of organic solvent).

Therefore, we can apply low cost printing and coating technology. Quantum dot shows bright strong luminescence emission light. In addition, emission light with wide range of wavelength can be irradiated with high efficiency, long life time and high attenuation coefficient. Therefore, quantum dot can be expected to be utilized for various type of application including medical experimental imaging, light source, display, solar cell, security tag, quantum dot laser, photonic material, transistor, thermoelectric material and quantum dot computer etc.

Solar Cell

Quantum Dots Security Inks

Solar cell with high efficiency can be prepared by low cost printing technology. Fluorescent dye which has been used already, have tendency to decompose as time elapse. On the other hand, quantum dot is the inorganic material and stable in this sense. Moreover, silicon based solar cell can only absorb visible light. In addition, organic dye is not applied to utilizing infrared light region. In this regard, quantum dot can absorb infrared to ultraviolet light just by modifying the particle size. Quantum dot exhibits high light absorbing efficiency even under weak light irradiation on such as cloudy days.

Bio Medical Imaging

Quantum Dots Security Inks

Since quantum dot is extremely tiny particle, they can be delivered to anywhere in the body. Therefore, they can be used for medical imaging and bio sensor. Moreover, by coating bio compatible polymer with quantum dot, they can be dispersed in blood vessels too. In addition, by binding with specific substances such as antibody, they can be used as target cell. At the moment, organic dye with wide spectra is used for fluorescent bio sensor. However, fluorescent color choice is limited and fluorescent life time is short. In contrast, quantum dot is able to emission light at all range of wavelength region. Also, they exhibit high efficiency and long life time compared to existed organic dye.

Electronics and Photonics

Quantum Dots Security Inks

Quantum Dots Security Inks

Quantum dot is in zero dimensions so that density of states is very distinctively clear and sharp compared to high dimension structure. Because quantum dot is extremely small in size, electrons do not necessary have to move long distance compared to large particle, thus signal response becomes very quick in various type of electronic devices. Owing to these electronic properties, quantum dot can be applied to transistor, solar cell, ultrafast optical switching device, logical gate and quantum computer etc…in addition, high density solid memory chips, LED, white solid light, back light, displays, photonics ink (security ink) and light detector etc…can be created based on quantum dot technology Generally, quantum dot is the semiconductor based on cadmium. However, these heavy metals are prohibited to be used in many industry areas.

ZnSe@ZnS 04

Therefore, demands are to develop cadmium free quantum dot which exhibits high light emitting efficiency and stability as good as cadmium based semiconductors. Nanoshel team is diligently researching and developing cadmium contained quantum dot and also, cadmium free quantum dots and we will continue to have more kinds of quantum dot products. In should be noted here that generally, to manufacture quantum dots in large industrial level have difficulty due to cost issue. Therefore, quantum dot is currently used for only in the field of bio medical imaging with small quantity business. In this regard, we are chasing technology to manufacture quantum dot in large industrial level in order to make quantum dot products with cheaper price.

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.

Shape Memory Fasteners

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 replace devices.

Rapid release fasteners hold more weight than commercially available detachable fastener systems and attach and detach with less force. Optional color-change alerts users when the material is ready to be fastened or removed.

Shape Memory Fasteners

The interlocking fasteners are made of a SMP and are designed to support heavy loads such as armor panels in high-shock or high-vibration environments. In the field, where time and hold strength is critical, these fasteners provide solid support and rapid armor application.

Shape Memory Fasteners

Rapid release fasteners offer simple-to-use, integrated activation. Coupling increased hold with easy removal, this technology goes a step beyond conventional detachable fastening systems.

Silent Fasteners

Another version of SMP fasteners that came out of this research can be used without heat activation for applications requiring a quiet fastening solution. These fasteners are made with flexible, mushroom-shaped polyps that “snap” together silently. While conventional hook and loop fasteners make loud tearing noises when being removed, silent fasteners, make no noise at all. This is a huge advantage for military applications, especially for uniform insignia, uniform fasteners, and other attachment needs when silence is important to survival.

Benefits

• Low-force attachment/detachment
• High fastening strength to support heavy equipment or detachable signs
• Applies to any surface, even contours
• No extra tools required
• Corrosion resistant
• Aesthetically pleasing, hidden fastening
• Tamper-proof
• Repeatable process without damage to the substructure
• Low force required to detach
• No framing needed
• Low sensitivity to environmental conditions

Some Applications

Shape memory fastening technology shows promise for military, household, and commercial uses. The following industries would benefit from smart fastener technology:

Shape Memory Fasteners

• Adaptable storage
• Temporary shelter assembly
• Hatch enclosures
• Architectural detail fastening
• Noiseless insignia fastening
• Noiseless fastening for military clothing
• Sign assembly
• Home and garage storage
• Emergency vehicle equipment storage
• Underwater storage/equipment mounting (no corrosion)
• Plant floor dividers/storage
• RV storage

It has high melting (Tm), glass transition (Tg) and continuous service temperature. It can be processed by conventional methods such as injection molding, extrusion, compression molding and powder coating techniques. Therefore, PEEK and its composites have been reported for use in aerospace, automotive, structural, high temperature wiring, tribology and biomedical applications.

Polyether Ether Ketone

Utilization of fly ash (FA) as an additive component in polymer composites has received increased attention recently, particularly for high volume applications for effective disposal of the material and reducing the overall cost of the composites. Fly ash is a waste material, obtained in huge quantities from thermal power plant as by-product of the burning of pulverized coal. It is a fine and powdery material. A microscopic view would reveal that the particles are essentially spherical. Fly ash has been used as spherical filler for the production of lightweight high strength concrete.

Polyether Ether Ketone

Mica is a plate like crystalline alumino-silicate and has been widely used as reinforcing filler in polymeric matrices due to its excellent mechanical electrical and thermal properties. The commercial delamination of mica may be characterized as wet or dry according to whether the delamination is carried out in a dry state or water. Wet grinding preserves the natural luster and sheen of mica and is normally characterized by clean cut edges, high aspect ratios, smooth surface, and ability to disperse easily.

Polyether Ether Ketone: Properties

PEEK is a high strength alternative to fluoropolymers especially in tough environments. Unreinforced PEEK offers the highest elongation and endurance of all PEEK grades. PEEK is also available as a composite or with carbon fiber reinforcement /fiberglass. However, PEEK is very expensive to process; hence it is widely used in major industries such as nuclear and aerospace.

PEEK is basically manufactured and used in low tonnages. It is also very expensive, thus making recycling a necessity. The use of thermosetting polymers is only increasing and it is now important to find ways to dispose or recycle them without it becoming a major global concern.
There are different recycling treatments available. Incineration process is a treatment with considerable non-combustible residues. Another treatment is thermolysis process which causes decomposition of products and mechanical weakening. Mechanical recycling techniques are based on granulation and comminution, which cause specific size fractions that can be incorporated into new sheet molding compounds (SMC) parts in a thermoplastic matrix, or in concrete. Solvolysis is a recovery method of composite wastes. Chemical recycling process is a proven and effective recycling method for plastics. Further research is ongoing and PEEK is not being recycled extensively at present.

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 of nanoparticles, that roll between the contact surfaces, keeping their shape intact; for high load conditions, a coating, induced by the presence of nanoparticles, is deposited on the crests of surface roughness and it can reduce direct contact between the asperities, thus, minimize wear.

NanoTech Lubricants

Graphene in car engine’s oil benefits lubrication and reduces fuel consumption

Because of the nature (inorganic and refractory) of the nanoparticles generally used as filler, the optimal performances achieved by the nano-lubricant can also be maintained in the working conditions at high temperature, thus avoiding the typical degradation of the traditional organic additives.

A major challenge to face, in order to scale up the use of nanoparticles as filler for lubricants, is related to their dispersion within fluids, which is often not uniform. Their small size, in fact, causes the attractive forces to rule over the other types of forces. This phenomenon generally causes aggregation and precipitation of nanoparticles. This issue shows that nanoparticles in lubricants need to be dispersed with other methods in order to optimize their stability, most likely they need to be surface-functionalized with organic treatments.

lubricants

A lubricant is derived from mineral oils or synthetic hydrocarbon blends. However, in order to fulfill the requirements set by the Original Equipment Manufacturers (OEMs), they lack properties of their own. A common solution to this problem is to include relatively small but effective additives in the formulation of the base stock, which leads to remarkable improvements to the attribute of the lubricants, such as introducing anti-oxidation capability, tribological characteristics, and thermal properties. Nanotechnology offers the opportunity to improve the performance of lubricant oil via the utilization of nano-additives. The addition of nanoparticles to common base oils is a promising approach towards enhancing certain characteristics, such as friction and wear resistance. This communication overview works on nano-additives in the lubricant industry. It encompasses general base fluids and common oil additives, and more narrow focus such as the application of nano-scale particles. Finally, this communication will highlight the future prospects of nanoparticles in the context of the lubricant industry.

Numerous nanoparticles have recently been investigated for use as oil additives. Nano -powders of some metals and their compounds exert an especially effective influence on the characteristics of lubricants. The use of nanoparticles that include Cu, CuO, Fe, Ni, TiO2 and other metallic nanoparticles additives in lubricating oils provides good friction reduction and anti-wear behavior.

NanoTech Lubricants: Most lubricants are liquid oil-based materials:

• Fatty acids
• Mineral and synthetic oils (groups I, II, III, IV, and V)

Nanomaterials (inorganic layered materials)

• Molybdenum disulfide (MoS2)
• Tungsten disulfide (WS2)
• Sp-bonded carbon
• Graphite
• Fullerenes/nanotubes

Using ‘hybrid’ Nanolubricants additives in metalworking fluids (oil-based, vegetable oil, and water-based MWF) Advantages

• Improvement in surface roughness
• Increase in G-ratio
• Spontaneous heat transfer
• Reduction in grinding forces

Suspended nanoparticles in various base fluids can alter the fluid flow and heat transfer characteristics of the base fluids. These suspensions of nano sized particles in the base fluids are called nanofluids.

Nanofluids are suspensions of nanoparticles in a base fluid, typically water. The term nanoparticle comes from the Latin prefix “nano”. It prefix is used to denote the 10-9 part of a unit. Recent development of nanotechnology brings out a new heat transfer coolant called nanofluids. These fluids exhibit larger thermal properties than conventional coolants.

The much larger relative surface area of nanoparticles, compared to those of conventional particles, not only significantly improves heat transfer capabilities, but also increases the stability of the suspension.
