What is nanowire?
A nanowire is particularly thin wire with a diameter on the regulation of a few nanometers (nm) or less, where 1 nm = 10 -9 meters. Two activities in nanotechnology by which nanowires can be manufactured are suspension and deposition.

A strung up nanowire is held up by the ends in a removed chamber, and then is chemically engraved or impressed with high-speed atoms or molecules to trim down its diameter. Another method involves indenting the surface of a wire in the center of a suspended area, raising the temperature, and then fleshing out the wire while it is near its melting point. A deposited nanowire is fabricated on a surface consisting of some non-conducting material such as plastic or glass. The process is similar to that by which semiconductor chips are mature, except that the result is a linear (one-dimensional) structure rather than a flat (two-dimensional) or solid (three-dimensional) configuration.
Fields likely to benefit from nanotechnology include water purification, sanitation, agriculture, alternative energy (particularly photovoltaic’s), home and business construction, computer manufacturing, communications, and medicine.
A nanowire is a nanostructure with the diameter of the regulation of a nanometer (10-9 meters). It is also explained as the ration of the length to width being greater than 1000. On the other hand nonowire can be as structure that has a very thin thickness of diameter embarrassed to tens of nanometers or less and a “significant wire”. Many different type of wire available in market, including cheep and best insulation conducting material e.g. YBCL, Molecular and super semi conducting material.  
Generally nanowires demonstrate characteristic as (length to width ratio) 1000 or more. Nenowires are often referred to as one dimensional (1-D) materials and also have many physics that are not seen in aggregate of 3-D (3 dimensional) materials. So, the electrons in nenowires are major kept laterally and thus inhabit energy levels that are goes to defer from the traditional continuum of energy levels or brands found in bulk materials.
Atypical features of this major kept sported by certain nanowires clear themselves in discrete value of the electrical conductance. Such discrete values come up from a major mechanical restraint on the number of electrons that can flow through the wire at the nanometer scale. The said discrete value is formulated as:

There is opposite of the resistance unit h/e2, which is around equal to 25812.8 ohms, and concerned to as the von Klitzing constant Rk (after Klaus von Klitzing, the pioneer of exact quantization) since 1990, a fixed conservative value Rk-90 is accepted.
An example of nanowire includes not organic molecular nanowire (Mo6S9-xIx, Li2Mo6Se6)   which can have a diameter of 0.9nm and be hundred of micrometers long.      
There are many appliances where nanowires have an important role in electronic field, opto-electronic and other nano electrical mechanical appliances or devices, as supplements in the advanced compounds, for metallic interrelates in nanoscale quantum devices, as  field-emitters and as commands for biomolecular nanosensors.

Palm oil substitute of transformer oil


Palm Oil: Palm oil is also known as dende oil from continental as a fit for human consumption vegetable oil derived from the mesocarp (reddish pulp) of the fruit of the oil palms, mostly the African oil Palm Eaeis guineesis and to a minor extent from the American oil Palm Elaeis oleifera and the maripa palm Attalea maripa.

Palm oil is certainly pink in the color because of great beta carotene content. It is not perplex with palm kernel oil imitated from the kernel of the same fruit, or coconut oil imitated from the kernel oil of the coconut pal (Cocos nucifera). The differences are in the color (raw palm kernel oil lacks caotenoids and is not red) and in the flooded fat content. Palm mesocarp oil 41% flooded, while palm kernel oil and coconut oil are 81% and 86% flooded respectively.

In respect to transformer, oil is known as coolant and also as insulating oil. In present, the petroleum based oil is generally used in the transformer as it expedients the requirements to be the perfect insulation. Petroleum oil gives negative impact mostly to the environment as when explosion, tank burst or leakage arise, the oil may pollute soil surrounding and water stream badly. Also it is a fact that petroleum based oil will not be available for usage to future generation. For this reason, supplementary studies invented that biodegradable oil has highest potential to replace petroleum oil as liquid in transformer for manage the best performance of the insulation in the transformer, free moving water particles in the oil must be mostly in low level. Free water gratified that exist will affect the all performance of insulation, so mortifying the life time of a transformer. If the oil can take up water and reduce quantity of free water, it will help reducing changes of the full insulation breakdown when the oil is a high moisture condition. Here, Malaysian researcher’s effort to use palm oil as insulation liquid for transformers. The said discovery discovers about various palm oil humidity absorption levels and it is directly effect to Voltage breakdown for transformer insulation system application.   Palm oil such as RBPO oil and red palm oil (Carotina oil) are evaluated with marketed transformer oils, mineral oil as we as palm oil fatty acid ester (PFAE) in terms of their humidity absorption level and voltage breakdown.

The silicone oil is used for good and powerful characteristics in the transformer insulation but environmentally is not good. So, the new oil has been discovered for transformer insulation as palm kernel oil for strengthens characteristics and good in respect of environment pollution.

This research is being presented at the festival of Postgraduate Research on 16 June.

Research by a University of Leicester student has discovered an environmentally friend and substitute of oil for industrial use. Abdelghaffar Abdelmalik has detected a solution as Palm Kernel oil by which can be insulating the transformer part in electrical transformer.

The petroleum derived oil is used to provide the insulation in between components of transformer, but due to fossil oil it is not good for environment at the time of burst or leakage.

Abdelghaffar, who is studying for a PhD in the University’s department of Engineering, was is hiking the probability of using an imitative of Palm Kernel Oil which is environmentally good, non-toxic and has suitable characteristic such as low conductivity. This would increase the life of electrical transformer and greatly maintained the effects of leakage or burst.

Abdelghaffar’s research has already been accredited as significant by the Dielectrics and electrical insulation Society, part of the institute of Electrical and Electronics Engineers, which last year awarded him a $5,000 research grant to support his innovative work.

“The results of the innovation work done so far are encouraging,” said Abdelghaffar “There are indications that this research may fertile a supportable useful in fulfillment of requirements of electrical insulating fluid that would serve as an effective alternative to the mineral based insulating oil”,
