Conductive and Insulating Materials

Materials They can be classified in conductors or insulators, according to leading electricity with ease or not do so. This classification depends on how strongly are United electrons to its structures, as this is an indication of the energy required to give them mobility inside the material, i.e. to conduct electricity.

This differentiation is useful within certain limits. For example, quartz

melt is 10 quadrillion times better insulation than copper, which is why both tend to be regarded as excellent insulator and conductor, respectively. Metals and non-distilled water are considered to be good drivers, plastics and glass are good insulators.

Water in its chemically pure State is an insulating substance. However, in nature are found in solution with other substances that occur in its structure ions with relative freedom of movement. In such circumstances, these solutions are very good conductive of electricity.

A strategy used to avoid accidents caused by the accumulation of static electricity is to increase the surface conductivityby elevation of relative humidity. Many times it is installed for this purpose an integrated team humidification system

air conditioning. The moist air conducts electricity and prevents the surfaces are loaded.
This classification are currently added materials called semiconductors such as Silicon and germanium, which are good insulators when they are in pure crystalline state, but they conduct electricity when only some atoms of the Crystal are replaced with others, such as arsenic or boron, using the technique known as taken drugs of the material.

Semiconductors have extensive technological application, for example in the manufacture of transistors.
Some materials that are considered good drivers increase their conductivity virtually infinite when it cools them at temperatures close to absolute zero (- 273 K): are the so-called superconductors.
Currently, found some ceramic materials superconductors at temperatures of more than 100 k. Isabela great expectations with regard to the design of superconducting materials to higher temperatures that would enable significant energy savings.

In conductive materials, the burden is distributed on the surface, which is easily understandable if one takes into account the repulsion between the equal sign loads and relative mobility available in good conductivity materials.

The concentration of load depends on the curvature of the surface, and can be verified experimentally that the maximum concentration occurs in the értices or tips.

The human body can be considered as a good driver. When the relative humidity is low, you can accumulate loads fairly high, caused for example by the friction of shoes with soil insulation.
The friction of the garments of silk, wool or synthetic fibres, that when withdrawals result in often small sparks electric also audible and visible as a weak Crackle can also be observed. 

These considerations become significant importance as to avoid accidents for those people who work with highly flammable materials and also for which handled with sensitive electronic equipment, that they might suffer some damage by the action of this small Download.

Biosolar: Solar panels with ecological materials

The solar energy is one of the most important renewable energy sources in the world. And solar panels are one of the most effective applications of solar energy. A new development makes it possible that these solar panels can be built with ecological materials, and so obtain a doubly positive for the environment..

Solar panels are essentially devices that trap solar energy and turn it into direct current of electricity. The work of solar panels is based entirely on the photovoltaic effect, hence the called photovoltaic panels.

This brief introduction is to explain the photovoltaic effect required to occur in elements semiconductors. Semiconductor materials mainly used are single-crystal silicon and polycrystalline silicon, which is found in each of the solar cells and are covered by glass or other materials to waterproof.

All these layers comprising solar panels are placed on a substrate or bottom layer usually contains materials such as polyester or Tedlar (a type of thermoplastic).

Solar panels can become a "greener" device, when they are made with organic materials. This is the proposal of the new BioSolar Backsheet Solar Panels.

These solar panels have a substrate (backsheet) are not built with chemical based products?in materials such as polyester and Tedlar, the most common currently. Instead this lower layer of the panel is made with a material completely ecological, obtained from castor seeds.

In addition to its ecological advantage, new panels of BioSolar substrate material shows a better thermal performance than conventional materials. The operating temperature is lower, which is also one of the highlights of this type of solar panels.

In general, this type of solar panels provides a better performance in terms of mechanical strength, electromagnetic properties, durability of long-term and adaptability to the climatic conditions. Apart from that, recycling of solar panels proposed by the manufacturer also makes this solar panel advanced and according to the demand of the contemporary world.

The almost any dependency BioSolar Backsheet solar panels towards the products of petroleum makes it - not only more suitable for environmental security – but also more economical. Given that oil prices are increasing day by day, the greater stability of the value of its raw material and a lower cost of production also are points in favour.

One of the criticisms which this type ofecological solar panelsis that it requires a specific and precise monitoring in order to provide an optimum temperature of work during the process of generation of energy solar.
