University inventions to respond to visible light-based solar cells
Cigarette in a glass box the size of nano-materials coated with a layer of new, used two wires to connect it with a small electric fan dell laptop battery and then the "glass" on the sun, a small electric fan whir to immediately turn up. Held in Nanjing University of Science and Technology recently recommended by the outcome of the special meeting, "in response to visible light-based solar cells" appeared, it aroused great interest of many entrepreneurs.
According to experts, the annual solar energy reaching the Earth's surface is equivalent to the world's total annual energy consumption 10,000 times, and the entire visible solar energy accounted for about 50%. How to improve sunlight utilization of visible light, scientists are exploring is the hot. Nanjing Environmental Materials and Renewable Energy Research Center, Professor Zou Zhigang, director of the group lies with the Japanese Institute of Advanced Industrial Science and Technology Cooperation, the first in the world to successfully develop a visible light response type photocatalyst water full decomposition. Professor Zou Zhigang said that this new type of solar cell power generation plant simulation of the main principles of photosynthesis. Experts say the world's most widely used solar cells are crystalline silicon solar cells, high-purity polysilicon extremely scarce in China, mainly dependent on imports, resulting in solar cells, "two out", and 90% of the raw materials imported more than 90% of all export products. Professor Zou Zhigang and they developed "in response to visible light-based solar cells", materials of crystalline silicon solar cells is only one-tenth, not only low-cost technology is also very simple at the same time, Dell 1G222 Battery,suitable for large-scale production, is very optimistic about the prospects for industrialization. Professor Zou Zhigang said that the most suitable for this new type of material used in glass, so the household glass, glass curtain wall buildings can make a solar cell block. In other words, the future of each family can have a small-scale "solar power stations."
"This battery is also the biggest advantage of the sun can be used not only for power generation, indoor lighting can also be used." Professor Zou Zhigang said, "We are currently doing research in cell stability, Dell 312-0292 Battery Dell INSPIRON 2600 Battery, Dell INSPIRON 2650 Battery, Dell 1G222 Battery,and updated technology to further reduce costs, so that as soon as possible into the life of ordinary people. "
Russia developed a new type of mobile phone charger
The use of cell phones will always be people without power and unable to charge the anguish, the Russian National Science Center Kurchatov hydrogen plasma process and the researchers solved this problem. They developed a new type of mobile phone charger, and simply do not need alcohol to do the power of the charging device materials.Dell INSPIRON 2650 Battery, The results of scientific research in Moscow not long ago, "international hydrogen energy technology," the exhibition attract attention.
The researchers pointed out that the prototype of the new charger has been developed, and its working principle is simple: alcohol solution (ethanol or methanol) has become a power converter. Diluted with 100 grams of alcohol satellite l15 battery, toshiba satellite l20 battery, in 10 small period of time such devices can be obtained from the 3.2 volts. This power charger is very small, only 350 mW.
The researchers said that the current prototype of the size of 13 กม 13 กม 1.5 cm, is connected by the 8 component of the box. A special production by the St. Petersburg of the ion-exchange membrane to form the prototype of both the anode and cathode electrode. In the anodic decomposition of the alcohol and water after the formation of carbon dioxide and protons in the cathode to form hydrogen ions and oxygen in the air a chemical reaction occurred. The release of the two chemical reaction of the electronic charge is used for mobile phones and used. Response in these two catalysts used. This catalyst is a known vector of the plating on the carbon content of fine dispersion of metal,Dell 312-0292 Battery Dell INSPIRON 2600 Battery, Dell INSPIRON 2650 Battery, Dell 1G222 Battery, the anode from platinum, Dell INSPIRON 2600 Battery,ruthenium and tin composition, the composition of the cathode by the platinum.
The researchers believe that the appearance of the current prototype is not perfect and the use of, 700 grams weight. But in order to solve the problem of the appearance of relatively simple, can be done quickly.
Guangdong exports battery new EU barriers
From Guangzhou Customs was informed that the European Commission last month to the WTO Committee on Technical Barriers to Trade TBT notification (notification No.: G/TBT/N/EEC/98 ))--" on batteries and battery and battery and battery waste directive approved common position and revocation of directives 91/157/EEC ". Clause 4 of the introduction of a portable battery 1b cadmium content of 0.002% of the new restrictions.
The EU claimed that the Bill is to protect the environment, prevent the waste of urban refuse cadmium batteries pollution. Customs said that the new implementation of the provisions of the battery in Guangdong will have a certain impact on EU exports, Guangdong battery export enterprises should take timely measures to deal with.
It is reported that as early as in 2002, promulgated by the European Commission decision 2002/525/EC, with effect from January 1 this year, may not be sold from metal cadmium batteries for electric vehicles. In addition, since July 1 this year, the European Union "in the electrical and electronic equipment on the Prohibition of the Use of Certain Hazardous Substances Directive" (ROHS) started to invest in the market of new electronic and electrical equipment shall not contain lead, mercury, cadmium, hexavalent chromium,Dell 312-0292 Battery Dell INSPIRON 2600 Battery, Dell INSPIRON 2650 Battery, Dell 1G222 Battery, poly and poly PBDE PBB. According to the directive, some enterprises in Guangdong's exports to the EU battery products, also contain the provisions of the European Union of certain hazardous substances, such as home appliances such as a battery accessories export the European Union, will be facing the same "green barriers." Dell 312-0292 Battery The EU is the main export in Guangdong battery market, manufacturers how to make the products satellite l25 battery, toshiba satellite pro l10 battery, toshiba satellite pro l20 battery, toshiba tecra l2 battery meet the needs of the EU market, has become a pressing need to be addressed.
