Description
N-Methylmorpholine N-oxide (more correctly 4-methylmorpholine 4-oxide), NMO or NMMO is an organic compound. This heterocyclic amine oxide and morpholine derivative is used in organic chemistry as a co-oxidant and sacrificial catalyst in oxidation reactions for instance in osmium tetroxide oxidations and the Sharpless asymmetric dihydroxylation or oxidations with TPAP. NMO is commercially supplied both as a monohydrate C5H11NO2·H2O and as the anhydrous compound. The monohydrate is used as a solvent for cellulose in the Lyocell process to produce cellulose fibers.

Description
N-Formylmorpholine is the organic compound with the formula O(C2H4)2NCHO. It is the formamide of morpholine (O(C2H4)2NH). A colorless compound, it is a useful high temperature solvent akin to dimethylformamide.

N-formylmorpholine is an important organic solvent and fine chemical raw material. It is a colorless, transparent liquid at room temperature. With the chemical nature of the amide, the aqueous solution is easily hydrolyzed into morpholine and formic acid in the presence of an acid or base, and the aqueous solution is weakly alkaline.Used for desulfurization of natural gas, synthesis gas, flue gas, natural gas condensate and gasoline, etc. It is the best extraction solvent for petroleum aromatics. It can recover aromatics by extractive distillation. It has good selectivity, thermal stability and chemical stability. Good, no poison, no corrosion. It is currently the most widely used recycled aromatic solvent.

Description
The MOSFET (Metal Oxide Semiconductor Field Effect Transistor) transistor is a semiconductor device which is widely used for switching and amplifying electronic signals in the electronic devices.  The MOSFET is a core of integrated circuit and it can be designed and fabricated in a single chip because of these very small sizes.  The MOSFET is a four terminal device with source(S), gate (G), drain (D) and body (B) terminals. The body of the MOSFET is frequently connected to the source terminal so making it a three terminal device like field effect transistor. The MOSFET is very far the most common transistor and can be used in both analog and digital circuits. We mainly focus on MV (40V to 250V) MOSFET in this report.

Description
Hydrodynamic Couplings, fluid coupling or hydraulic coupling is a hydrodynamic or 'hydrokinetic' device used to transmit rotating mechanical power. Fluid couplings are a type of hydraulic coupling that uses water or oil for the transmission of power/torque through shafts. These devices provide controlled start-up and reduce shock loads during the power transmission process. Fluid couplings are used by end-users such as oil and gas industry, metals and mining industry, chemical industry, and power plants.

Description
Super-junction MOSFETs are a key innovation in high-voltage MOSFET technology. They offer better features such as reduced gate capacitance, reduced on-resistant of the circuit [RDS(on)], and lower output charge with reduced die size. Super-junction MOSFETs have a significantly low gate and output capacitance. Super-junction MOSFETs are currently available in a variety of packages, with body diode characteristics and voltage ratings to meet different application requirements. Thus, they are increasingly being used in high-voltage switching convertors, allowing efficient switching at any given frequency.

High-voltage MOSFET is a type of MOSFET which operates at a voltage above 200 volts. MOSFETs are integrated into a system depending on the voltage at which they are operating, thus, the MOSFETs are selected on the same basis. High-voltage MOSFETs are used mainly for industrial applications and in the area which require high power amplification and switching.

Description
A flange coupling is a type of coupling device meant to bring two tube ends together in a flush, sealed manner. This two-piece coupling unit consists of a keyed receiving side for the flanged end to be fastened to, so it may be married to the opposing tube end, which also has a flanged end. Each flange has either a male or female coupler opening so that when the two ends are brought together, they are aligned without causing resistance or drag in the material being passed through them. This male/female coupling method also creates a stable connection that is resistant to shifting, keeping the flange coupling sturdily in place.

Flange couplings are typically used in pressurized piping systems where two pipe or tubing ends have to come together. The connecting methods for flange couplings are usually very strong because of either the pressure of the material or the sometimes hazardous nature of materials passed through many industrial piping systems. High thread count nut-and-bolt connections are used to secure the flange couplings in place. These nuts and bolts are usually made from tempered steel or alloys to provide enduring strength and the ability to be tightened to the utmost level to ensure the piping system doesn’t leak at any flanged junction. Most flange couplings utilize four, six, or up to 12 bolt assemblies.

Description
Dipropylheptyl Phthalate (DPHP), Di(2-propylheptyl) phthalate, Bis(2-propylheptyl) benzene-1,2-dicarboxylate or di(propylheptyl) orthophthalate, commonly abbreviated DPHP, is an organic compound with the formula C28H48O4. It is a phthalate and is the diester of phthalic acid and the 10-carbon branched-chain alcohol 2-propylheptanol. This colorless viscous liquid is used for softening PVC plastics and is a general purpose PVC plasticizer.

It is used as a main plasticizer in construction for the manufacture of covers as it provides extraordinary properties for weather resistance. In addition to this application the product is also used for the manufacture of cables as well as for other applications in the automotive industry.
