Concrete That Cleans The Air


 Tecky News : (  Latest Tecknology As Used To Concrete That Cleans The Air )

Emissions that are the result of burning regular fossil fuels (like the fuel in your car) are made up a massive amount of different compounds. Even if we are able to reduce the emission levels of one of these compounds it is a good thing and will help bring down the pollution created by driving. That is where the research done by researchers at Eindhoven’s University of Technology in the Netherlands will become a formidable method to reduce the global ecological damage caused by cars that are on the road. They have developed a concrete that strips nearly fifty percent of the nitrogen oxides from exhaust emissions.
 The concrete was developed in a laboratory and after extensive testing a one thousand square meter stretch of road was laid to test the concrete in a real test of its potential. The concrete works by stripping nitrogen oxides from the air and converting them into nitrate (a nontoxic compound) as the sunlight and concrete worked together to break it down. The nitrate is then carried away by rain and never seen again. So it not only turns a once toxic chemical into something benign – but using the forces of nature makes the problem virtually disappear.
It is assured by those who can supply the concrete that the cost incurred is not really much more than that of regular asphalt or concrete. In this regard it can be considered economically sound as well as ecologically. It can also be mixed with regular concrete and asphalt without jeopardizing the structural integrity of the latter materials. It may just be an easy way for roads to do something extra besides protect a vehicle from unnecessary wear – it will also help reduce the environmental effect of having many cars spewing forth noxious fumes from their tail pipes.

Web 2.0


Tecky News : (Latest Tecknology Used In Internet As Second Generation Name As Web 2.0)

Our online world has changed so much in last few years. Every day, we listen about some new events, new software or a new technology that keeps making our world a easier place to place. What we have now is, Web 2.0. If you are not aware of it then let me tell you, it is also considered as the ‘second generation’ of the Internet. Web 2.0 is a concept. Don’t go by its name and it is not something that can be purchased neither it is an updated version of any software. In other words, Web 2.0 is a way of doing thing on internet in a different way.
Let me explain you. Remember those old days of early 90s? We used to surf web, download software and use it. There were things like chat messenger, online forums etc. Now, what we have is much more than that. We are not just restricted to these mundane activities. We interact with internet. We use blogs and use social bookmarking. There are number of good social networking sites using which we interact with the rest of the world. We can now develop a website in a single day and have it up and running.
Web 2.0 has its core several new concepts and specific technologies. But the essence is interactivity. Sites catering to web 2.0 are becoming increasingly popular because people can interact with and through them. And how can we forget importance of video in this concept. Remember, Internet marketers are making full use of this concept. Of course, there is lots of money to be made. Now, all we are waiting for is Web 3.0. Who knows, what fortune that will bring to us!
