Solar Cells Permanently New flagstones that cleans the air

oxide concentrations of nitrogen in the German cities often exceed the maximum permitted levels for this compound toxic. This situation may now be about to begin to change. Change will be installed as a novel flagstones that will help protect the environment. Coated with titanium dioxide nanoparticles, these unique stones reduce the amount of nitrogen oxide in the air.

In Germany, the air quality is not always as good as could be. Data from the Federal Ministry of the Environment are clear about that. In 2009, the quantities of toxic nitrogen oxides in the atmosphere exceeded the maximum permitted levels of not less than 55 percent of monitoring stations in urban areas. The ministry reported that motor vehicle traffic on the roads is one of the main sources of these emissions.

Following these events, the city of Fulda is currently the scene of a pilot program to test the effectiveness of this new way to combat air pollution. All along the street Petersburg, will be placed slabs of this special class that will hopefully clean the air pollution cited excessive nitrogen oxide. In the street, pollution levels recorded last year exceeded the annual average limit of 40 micrograms per cúbico.El titanium dioxide covering the slabs becomes nitrate nitrogen oxides and some other harmful substances. Titanium dioxide is a photocatalyst, using sunlight to accelerate a chemical reaction that occurs naturally in appropriate circumstances. The speed of this reaction increases as exposure of the material makes the light air cleaners solar.Las slabs were developed by the company Nüdling Betonelemente FC. Has verified its effectiveness in the Fraunhofer Institute for Molecular Biology and Applied Ecology in Schmallenberg, where investigators also found the risk of nitrates resulting to the environment.

Biochar ... Less Emissions of Greenhouse Gases? Regional Expociencia

To 12 percent of emissions of greenhouse gases caused by humans worldwide could be offset so sustainable through the production of biochar, a charcoal-like substance made of vegetables and other organic materials. This is more than could be offset if the same plants and materials to be burned for energy. This is indicated by results of a new study.

These calculations show that biochar can play an important role in the fight against global climate change. "Biochar offers one of the few ways to get energy while reducing carbon dioxide levels in the atmosphere. And improving food production in poorer regions the world by increasing soil fertility, "says one of the study's authors, Jim Amonette, a chemist specializing in soils, Pacific Northwest National Laboratory.

The study is the most thorough and comprehensive analysis conducted to date on the global potential of biochar. In 1993, the substance was first suggested as a way to counter climate change. Scientists and government authorities have paid increasing attention in recent years.The new study has been carried out by Dominic Woolf and Alayne Street-Perrott, University of Swansea in Wales, United Kingdom, Johannes Lehmann of Cornell University in Ithaca, New York, Stephen Joseph, University of New South Wales, Australia, and Amonette.

Biochar is produced by decomposing plant biomass, including wood and other organic materials, high temperature, in a process called pyrolysis lenta.En normal conditions, the biomass decomposes and releases its carbon into the atmosphere within a decade or two. But the biochar is more stable and can retain its carbon for hundreds or even thousands of years, delaying the release to the atmosphere of greenhouse gases like carbon dioxide.

Other benefits of biochar include: An improvement of the soil by increasing the ability of it to conserve water and nutrients, reducing emissions of nitrous oxide and methane from the soil, and during the slow pyrolysis process, the production of some biofuels may help offset greenhouse gas emissions from fossil fuels.

Rules Of Diaper Punishment

Movistar

As users of telecommunications services in general will agree that the remaining commitments usually a contract clause that generates big headache for many users.

In fact, if all was well and we did not have any problem, no more inconvenient would meet the happy stay, but just when a problem arises when comes out this clause.

For this reason there are many people looking for products that do not require to remain tied to the company in question for months and months in which we have to keep paying for a service that we are not comfortable.

Unfortunately, among the various deals offered by Movistar when ADSL service contract exists only a form that does not include long-term contract, and fair is the mode with the download limit.

is the Mini ADSL, which offers a download speed of 1Mbps but limits the maximum traffic that can be downloaded to your computer to 2GB. The additional traffic will be charged to our account at a rate of 5 € for each additional 2GB.
