Viruses running Batteries future



Future power electronic devices that are running can be in the form of a very small battery sizes up to half the size of the cells of the human body is made of viruses.

Researchers from MIT in the United States of America believe they were able to build such battery, through the casting mix engineer genetically a component of the virus M13 and the metal cobalt precipitated on a slice of silicon, Professor Angela Belcher and her colleagues made the battery microscopic soft easy to manufacture large quantities of them.




Theoretically, it is possible to transform any surface - from a huge detector to a small implanted in the body to monitor the cancer cells or to monitor the work of the heart - to a device for energy storage.


Note that Belcher and her colleagues were able to produce a first viral battery in 2006. Since that time, you are trying to improve the performance of viral battery to enable them to access to the source is too small to store energy that can be grown or buried in sensors or small devices.


Forget the Batteries 9 volt batteries and AAs and the AAAs or D batteries so that the standard used to run most of the hardware: the near future promised by electronic working batteries viral source (iStockphoto).


I've posted the details of this achievement was published in the Conference of the National Academy of Sciences, which show that the battery viral based on a substance called al-Qaeda and are mostly of silicon and collects the viruses M13 negatively charged atoms Article cobalt shipped a cargo of positive technology known as print or stamp Stamp.


Are printing on the material base and theoretically could be the norm any surface available, which means that viral battery that can make the lowest cost and high efficiency and many forms of flexibility and be able to install it in any form.
Alparvissourp Belcher says that the viral power of the battery than the battery twice chemical battery, although the virus is very small and reaches a few micrometers in diameter and requires a production period of time within the hour.
Belcher was able to produce viral-sized battery button shirt and used to run the laser pointer and this was the first attempt will certainly be the next test to run more of the devices by the battery, says Professor.
Are grouped viral battery at room temperature and used a small part of metal such as lithium or cobalt.


Applications
Because these batteries are very small it suitable as a source of energy for small devices such as devices that can be cultivated in the patient's body to monitor his health. Says Professor Belcher said that this technology has important applications, including monitoring the health of people living with heart disease or cancer, as the person who undergo surgery as a treatment of these diseases need to continuously monitor the performance of biological functions of different, and precision instruments and implants can be operated with batteries viral control protein resulting from the cancer cells renewable.


In the case of a threat, these devices will be issued to the light from the LED bulb, for example, to alert the patient and the nurse. May be the cause of saving the life of a patient before he suffered a heart attack.


Professor Belcher is very close to the development of this technology is expected to be valid for use and has many applications within the next two years.
It is also possible that scientists can increase the power of these batteries to be able to run computers or even a car battery was planted on the roof of the car instead of being placed next to the engine.


Professor Belcher says that the battery produces as part of the manufacture of the car where the roof is provided appropriate ion battery and the building itself.

Powerline Networking

The definition of the service: we recognize today on a new service known as somewhat of this service (Powerline Networking) In terms of technical service are the same as Broadband Over Powerline 100%, but there is one difference
Broadband Over Powerline service is the ability of high-voltage lines on the transfer of Internet service From places to places other far may not be available where the telephone service or DSL services to reach homes To move across the internal electricity network in the home.
The service is a service Powerline Networking create a network within the home via the electricity network by using special equipment, allow users to share files, video, photos, and of course, Internet service, if any. This service speeds up to speeds of up to 14 MB / s 0.85 MB / second (in some products).
If, after today, no need to extend the wire network and is pleased Imenta or under mattresses, or walls cracking or distortion of the outlook for the extension of this network service you all are going what you want the best possible way .. Since the products of this service is available in many shapes and attractive colors and Ariah
www.o7ida.com Electronic
Is based on the service to international standards? Powerline Networking service, of course, based on several standard Has been awarded this standard of service on the committee and got the IEEE standard IEEE 802.3, IEEE 802.3U and also the basic criterion that you know it this service HomePlug 1.0.1 Has obtained several certifications, including FCC, CE, HomePlug 1.0.1.

Is clear from the previous standards and certification that the service is very safe and do not cause any problems for the electrical equipment at home and do not cause any interference.
Can being the reception of such service if it has the same equipment? Of course if the same electrical control panel SEP, but you should know The service is transmitted on a standard 56-bit strong encryption, which means he will not be able to participate If you do not allow him to its reception.
What equipment is available for that service? Available in that service all the equipment available for wired and wireless services, for example

example of how to use such equipment, to look to the next image


Basic internet access, printer, and of course computerWe want to share the room B, C on the Internet and participate in printing and alsoShare files from the device is located in Room A
We will need to router, so we'll use the Powerline Router
Room B having several computers enabled Centrino (available by the Wi-Fi)If required is Wireless Powerline Access Point
Room C having multiple devices contain a network card aether ForumsIf required is Powerline Ethernet Bridge after exitsOr may be we can use Powerline Ethernet Bridge with one exitWe then plug it Psoic

Finally, I want to explain some important specifications to know how each of us selected the proper equipment:

Benchmark Standards • IEEE 802.3 / 802.3u preferably be subject to these equipment calibrated at least
Privacy Privacy 56 bits DES encryption
Data Rate Rate Statements 14 MB in standard equipment and 85 MB of equipment Super
Certificates Certifications FCC, CEAt least
Power Outlet110-220 volts
Features FeaturesShould at least be supporting the equipment service for more than 250 metersOperates up to 300 meters
Of sharing the gaming service Connects with game consoles

Number Of user the number of usersThis equipment has a limited number of users on a network of electricity must not be less than 10 users
Warranty WarrantyOf course, at least a year

Latest solar products: solar charger and solar lamps











Latest solar products: solar charger and solar lamps


Always eternal love and my passion and my love of all that is new in the technology uses solar energy and I follow every day the latest research in this area, Focus of developed countries in research on the two axes are more efficient equipment and reduce the cost and other news announced in this context is the announcement by Sun Bauer of America that it has achieved a new record in the efficiency of generating electricity from solar energy, which reached 24.2% the news was announced days ago Low is the Arabic language in the following linkMore here

Egypt and Abu Dhabi, Saudi Arabia and Morocco, and most Arab states are preparing to be the centers of mega-projects to generate clean electricity from solar energy and has already started to these States is taking steps in this direction with the participation of European Union, which announced a few days ago his intention to increase its reliance on solar energy by importing clean energy from the countries of North Africa during the next five years, the news is in the Arab Reuter
More here


The products that are already asked in the market and a solar-powered, they are many, but still the market in anticipation of what is the best efficient and less expensive shipper, who works in solar and grandmother sold in one Arab sites at 75 SR
Also solar lamp Modellath forms and multi-grandmother is widespread in Chinese websites


www.o7ida.com Electronic








There are also solar systems that come out enough electricity for domestic consumption but, unfortunately, even now prices are high, found in a Chinese sites System sufficient for the consumption of flat price of 15 thousand dollars and shelf life than 25 years, I expect that in the next few years that the price of this Astim solar will be less than aspiring consumers much

Wonderful and amusing ideas can be applied
Did you know that there is no way to make a candle is not extinguished the flames blow, and the only way to extinguish them is to prevent oxygen from her!!! In order to do this wonderful experience you bring a piece of cotton or linen, and salt and a candle, now Mark piece of cotton or linen saturated with salt, then wrap this piece of saturated normal candle and then lit Himtk wonderful and tried to extinguish them?!



How to spark a fire without sugar?


It is well known that sugar does not burn, but some people who are gaming the magical setting the sugar but Icallonh without fire, and this process is very simple when chemists, what does this game magic the dish half containing more than 25 grams of sugar and the other half contains 50 grams crystals of potassium chlorate, and deceive the audience to prove to them that the dish contains sugar, however, that provides them with the first half of the dish Itdhuqoh, and then drives his rod wet pre-concentrated sulfuric acid, and closer to the crystals of potassium chlorate, sugar, without triggering a fire!

Important Note: This experiment a little bit dangerous, in order for you by you go to a large yard and it does not its experience in the laboratory.




Floor firearms

Did you know you can write a word on a tablet of white paper is glossy center solution of potassium nitrate? But what is the use of this word? The word that you type in this manner are not visible, but if you make a wire heated to redness touch the first letter of the word, the fire will burn to form a word from the fire!



Newspaper does not burn with fire

We all know that the paper made of paper, paper and burn if set on fire, but the way we make this chemical does not burn the paper! We just need for solution of alum to do this experience fun, initially try to bring a solution of alum saturated, then dip the paper in this solution several times, and then drained and dry until they return to their normal, now we got our wonderful, if you suspect that the effect of this experience you must try and make sure of the result!




Volcano near your home

Do you want to make a volcano industrial near your home, if you first have to dig a hole in the soil dry a depth of 25 cm, then Make a mixture of powdered sulfur and iron filings soft and plain water until it becomes a mix Kalmajun, and then bury the mix early in the morning in the crater that Hfernaha Shortly before - but this experience will need to hot weather - and then after about ten hours you will see that the earth will split up to date crater out of which fire and smoke yellow oblique to the overwhelming and like a real miniature volcano too!



Egg fly without wings!!

This experiment, despite its simplicity but it is enjoyable, we need to experiment to distilled water and an egg only, now you bring the egg and the work of a very small hole, and then finished with an egg of its contents through this hole, then fill the egg with distilled water through this hole, and now you fill this hole and painted a color similar to the color of the egg so as to hide the hole from the others, now offer egg to bright sun, and is only moments to go up the egg in the air and fly!



Cleaning iron from rust!!

The corrosion of iron annoying, and the process of removing it is very important, and here we have a simple way to remove this rust, first brought sulfuric acid diluted with water by 10: 1 - every part of the sulfuric acid offset ten parts of water - and then wear protective gloves on your hands, and now clear the surface of rusty iron dilute sulfuric acid several times, and you will see that the rust has disappeared!
