This progress brought on detailed understanding of chemical processes will help us improve the catalyst , drugs and even aspects of the process of solar panels for sale .

Now, chemists around the world every day on the computer to design and conduct experiments . This scene was made possible , it has benefited from three scientists : Martin Karplus, Michael Levitt and Arieh Warshel in the 1970s began to work . They carefully examine the complex chemical processes each small step , but these details are usually difficult to detect visually .

A picture is worth a thousand words , but not all

In order to facilitate the general reader to understand the significance of this achievement , we are here to illustrate . Suppose now that you receive an experimental task : to create artificial photosynthesis. This occurred in the plant leaves into the magical chemistry let oxygen in the atmosphere is full , and this life on earth basis for survival . However, this perspective for environmental protection are equally important - if you can mimic photosynthesis mechanism , then we will be able to create a more efficient buy solar panels  When the water molecules are decomposed to produce oxygen will , but also can be used to produce the energy of hydrogen. Therefore, to carry out work in this area has great appeal and value. If you succeed, you will be able to help the world fight against the greenhouse effect.

First, you may need to go online to find proteins involved in photosynthesis dimensional fine structure , which in some large databases can be free. On your computer, you can freely be viewed from all angles . These huge protein molecules may contain hundreds of thousands of atoms. In which there is a very small area , called the reaction center . It is here that the water molecules are broken down .

New materials, titanium dioxide market research analysis operating conditions

A latest news, USTC reveal anatase titanium dioxide (commonly known as "Titanium") surface of the catalytic activity and the microscopic reaction mechanism, which is expected in the preparation of organic solar cell panel  solar energy into chemical energy environmental protection has made application. Titanium dioxide is not just the use of force end of this isolated cases. Overseas media have even pointed out: Multipurpose titanium dioxide will replace a wide range of applications of graphene has become "the world's most useful materials."

An agency who told reporters on zhengbao, titanium dioxide traditional downstream, such as paints, textiles, paper and other medium-term is difficult to see continued rapid growth, but environmental protection, new energy, high-end equipment, medical and other fields of new materials will become the titanium dioxide a transition from traditional to high-end shortcut.

Have been breakthroughs in the use of titanium dioxide

Recently, in the new energy, environmental protection, high-end equipment, medical and so on, almost every field of new materials breakthroughs, titanium dioxide can be found on the scene. Domestic institutions on the Shanghai Securities News reporter who said that the so-called overcapacity just encountered a bottleneck in the development of traditional areas, once the new technology, new materials breakthroughs, titanium dioxide limitless space for future development.

USTC latest scientific research team will be incorporated into the new energy development dioxide territory. USTC scientific team recently pointed out in the paper, titanium dioxide as an oxide semiconductor, solar energy conversion research is an important material system. Prepared in organic solar cell  the solar energy into chemical energy and other environmentally friendly aspects of the application is expected to achieve in the photocatalytic splitting of water and artificial photosynthesis and other aspects of hydrogen promising.

Recently the Australian National University supercapacitor study, titanium dioxide and then play a leading role. In the super capacitor manufacturing process, the Australian side found a way to store more energy, a smaller loss of insulating material - indium composite coating with niobium rutile (titanium dioxide). Rutile is a relatively pure titanium dioxide, rutile titanium dioxide production is the best material.

In the field of environmental protection, titanium dioxide is transformed into a multi-purpose flexible filter membrane. It is understood that this versatile flexible membrane filters can be used to improve battery life, water purification, manufacturing antimicrobial medical materials. The use of titanium dioxide in the field of environmental protection is also extended to the prevention and control of air pollution. In the Netherlands, scientists are studying the titanium dioxide mixed with asphalt or concrete, eliminating vehicle emissions, 25% to 45% of nitrogen oxides to reduce pollutants in the air.

Onto the roof, Journey Into Amazing Caves

In addition to expanding the use of the roof space, there is an advantage of abundant sunshine, do not worry about lighting issues. Thus, green roofs, rooftop solar controller is through the distance from the sun strengths to achieve people's environmental dreams. The popularity of the concept of green roofs, all the major international cities are popular since the hanging gardens.

Engaged in the cause of more than ten years green roof green roof Association Secretary-General Wang Xianmin world view, green roofs can cure many of the "modern urban disease" - the winter haze, summer urban waterlogging and lead to high temperature heat island effect, can be Green roofs relief, because green roofs help purify the air, rainwater harvesting, cooling insulation.

According to Wang Xianmin observation, Germany is the green roof of the "leader", as early as 1982 began this legislation. Later, Japan, Singapore, the United States, France, are followed, from legislation to encourage green roof. Today, Japan's rate of new construction of green roofs is 100%.

In the specific practices, the German legislation, reported that construction of new buildings must have green roofs, even in rural areas, too, tend to give developers and the government subsidy of 50% to 100% of the green roof construction fees. If there is no roof greening, the government have the means - to close the drainage fee. This is because there is conducive to establishing a green roof rainwater collection system, if the roof bare, will increase the pressure on urban pipeline.

About green roofs, although China is currently no legislation to be encouraged, but Yang Baojun said, as long waterproof, load problems can be resolved, in principle, is encouraged. And Wang Xianmin believes that developers should take up this responsibility, after all, "real estate construction costs greening costs account for only 1/1000", and the construction of a green roof waterproofing system, you can also extend the life of the house, "This is the sustainable development vision. "

In addition to direct green outside, the roof construction of solar energy projects, make full use of clean energy, but also the roof is a major contribution to environmental protection. Or in Germany, thanks to January 1999 from the implementation of "100,000 Solar Roofs Plan", residents have set up buy solar panels on the roof, the electricity in addition to their own use, the remaining can be sold to the grid company, and received power fees. According to 2010 data, relying on the rooftop power generation, some German families can earn 1,500 euros a year.

Photovoltaic Association criticized the French government cut the tax credit program

French Renewable Energy Association Syndicatdes Energies Renouvelables (SER) solar regulator branch SOLER criticize the French government in its 2014 budget plan to cancel residential PV systems 11% tax credit.

SOLER said that despite the beginning of a government assistance, but the first half of 2013, France's new PV installed capacity is only 207MW, the market still depressed from 12 months to recover.

According to the Commission on Sustainable Development data, due to lack of policy support, the first half of 2012 and the first half of 2013 fell between the new PV installed capacity by 78%. SOLER claimed that without government aid some of the china solar panel manufacturer may not be able to survive, resulting in the loss of hundreds of jobs. French residential market now accounts for a quarter of the domestic solar industry.

On Wednesday, the French government announced its 2014 Finance Act and the draft, in December before the need congressional approval before implementation. Finance Act detailed plan for the coming year in government spending. Government is facing tremendous pressure, will account for 2013 GDP4.1% budget deficit down to 3.6% of GDP next year, partly in order to reach the EU Commission requested the national debt.

This draft International Photovoltaic Research Conference on EUPVSEC released on the eve of the meeting will be held September 30 to October 4 was held in Paris, France. Government draft also includes polluting cars, activities and energy / petroleum products by imposing punitive taxes proposal.
