Making Home ? Must Have Electrical Fitting Components

The fitting of electrical devices comes on the top of the priority table, while making a home, once the brick work is over. As the Christmas is nearing by and you can't afford to wait entering your newly made abode.

Thus you need to be well planned because you have less than one month in your hands and you want to see one of the best electrical devices being installed in your home.

So to avoid any mishap which may cause unaffordable delay, you must make a trip to the electrical fitting components store nearby and come back with a bagful of following stuffs :


Bolts : While fitting some electrical devices, you need these look-like-rod-in-shape components. They come with external threads which help other components with internal threads to make a support.

Buy a set of bolts consulting the electrician. The set must include bolts of all types such as fully or partially threaded, long and short ones. Also buy a variety of bolts on the basis of their varying thickness.

Clips : When fitting certain things like cables and wires, lead-acid batteries, fuses etc, you need them to give them a sufficient support system which can hold them tightly. Thus don't forget to buy clips, These are available in a wide range as per their usage.

Conduit Fittings : Your electrical wiring needs electrical pipes for a sustainable protection. And in the same way these pipes are needed to be given a support base to avoid any breakage in future.

Also these pipes need extra care so they don't fall down. Thus not buying conduit fittings seems impossible. Buy a set of all the types of conduit fittings such as; electrical boxes, expansion fittings, sealing fittings etc.

Electrical Fasteners : While your wiring goes on, you need to join a number of electrical circuits and and connect various electrical objects together. For this purpose, the electrical fasteners are used.

Moreover, they help you to give proper alignment to the objects. Have a detailed look on your needs and buy electrical fasteners as per need. A lot of varieties as per their usage, design, shape and size and the metals used are available.

Electrical holders : To fix certain things like light bulbs, batteries, lamps etc and to provide them power supply, the electrical holder is an urgent thing. These are available in various shapes and designs which may make the wiring process much exciting.

However, I must say that this list doesn't include all the electrical fitting components you may require during the wiring. But the list include all major and important ones. Some other stuffs you may need are; electrical terminals, electrical mounts and rails, wire nuts etc.

Chemical Sensor That Runs Without Battery

A chemical sensor, the latest in the line of advanced chemical sensors, is claimed to run without battery, under the variable conditions, making the detection of the concentration of various chemicals much cheaper and easier.

This was confirmed by Radislav Potyrailoat, a scientist at GE Global Research. He also headed the multidisciplinary wireless sensing development team, comprising polymer scientists, analytical chemists etc, which developed the sensor system.

“Without the need for batteries, we can make sensors that are much smaller in size and at substantially reduced costs. Because of that, he said. They also can be made for one-time use.”

This product, a testing and measuring equipment, is a brainchild of GE Global Research. Only last month, the researchers, engaged to the development of technological aspects, came up with this fascinating innovation.

There are great similarities of mechanism between any conventional radio-frequency-identification tag(RFID tag) and this innovative radio-frequency-identification sensor. However, the prominent difference between them is that the RFID sensor has a coating of chemically or biologically sensitive film.

This ultra sensitive film helps in the detection and measurement of various chemicals. It detects chemicals with equal precision whether in different mixtures or in all variable conditions.

As a matter of fact, this sensor is helpful in the detection of trace concentration of toxic gases such as toxic industrial chemicals. The same can be done with all volatile organic compounds and chemicals in liquids.

Then how this chemical sensor works without batteries? It has got a sensor reader for this purpose which provides it the required energy. The radio reader does so by activating the RFID chip and a sensor antenna.

Main Feature :

The unique selectivity is being regarded as the sensor's best feature. This selectivity helps to assess things better as it minimizes or removes completely the chances of inviting faults and flaws. The accuracy in the detection chemicals helps to come up with good products. It detects contamination in water and food, concentration of toxic elements etc of any amount. This invention is going to raise the standard of the services in the fields like food packaging, water supply etc and will help to curb air pollution.

Inducing Superconductivity In Insulators

Trying to maximize the density of charge in semiconductor devices is always exciting and has remained a challenge. The continuous trials and researches in this regard seemed to have come up with some satisfying results.

Now the scientists have found out certain dielectric materials which can help increase the density of charge in insulators to almost twice in intensity.

There are two ways to maximize the density of charge; using impurity atoms and using external electric fields. The former is popularly known as “doping.”

However, the things like FET( field-effect transistors) not welcome the induction of superconductivity wholeheartedly. Thus this brings a halt to this process. It all happens because of their insulating layers made of oxide.

But according to recent researches in Japan, a superconductive insulator, made of organic current-carrying material, having salt mixed polymer, is a possibility. It will work efficiently in all the FET structures.

To make a super-thin superconductive insulator, they used things like; an insulator, a platinum electrode, strontium titanate, an electrolyte and a mineral for the purpose of layering. For the purpose of electric leads and contacts, they used two gold islands on the surface of SrTiO₃ .

Then came the time of its real test. As soon as the scientists made a voltage pass through the golden islands on the platinum layer, the density of the charge was doubled up. It was equal to the job done by a double-layer capacitor.

The electrolyte works as an dielectric. When the voltage passes through the surface, the positive and negative ions get charged up and start splitting. Thus we see them flowing towards opposite directions. The positives go downwards while the negatives head upwards.

Thus on the SrTiO₃ surface, between the golden islands, we see a huge concentration of negative charges. This happens to form a conduction path. Thus doubling up the workability.
