Shenzhen and CTIA Battery Certification in Asia first half the cost of laboratory tests
Asia's first mobile communications industry by the American Association (CTIA) certification formally approved battery officially designated laboratories located in Shenzhen last weekend. This means that the internationalization of Shenzhen in the battery and integrated services has taken an important step. In the future, Shenzhen and even the battery manufacturers in Asia or the cell phone manufacturers to export to the United States CTIA (and its affiliated operators), can be detected near the Deep, the move can save half the cost of testing vendors and testing time.
It is understood that the current global cell phone battery, especially when accidents occur, the world for the batteries are very concerned about security issues. The CTIA IEEE1725 ("IEEE" for the Electrical and Electronic Engineers abbreviation) battery system certification has become a telecommunications operator in North America the mandatory access requirements. The standard rechargeable lithium batteries for mobile phones developed mainly a series of testing and validation of specifications and methods, established the mobile phone battery design, manufacture and evaluation of the uniform requirements. The certification process includes product testing, design and manufacture of document review, the manufacturer declared and so on. This reporter learned that, after the certification lab located in Shenzhen, the country has been received from four or five mobile phone vendors for certification.
Luan Shu, general manager of Shenzhen Moore Laboratory, the new Shenzhen approved laboratory, will be mainly for export to the U.S. mobile industry association CTIA IEEE1725 battery authentication. It is the mobile communications industry associations in the United States approved the first battery in Asia certified laboratory. In addition to Asia, but now its only one in the United States outside the designated accredited laboratories in Europe.
Ohio University researchers said, when production on the Earth's environment-friendly solar energy, the pink may be a new "green color." Scientists have developed a new dye-sensitized solar cells (DSSCs). The red dye used in the battery and the white metal oxide powder mixture showing pink, can capture sunlight.
Allegedly, these new pink materials, photoelectric conversion is the best material, although the conversion efficiency is only in commercial applications, half of silicon solar cells, but its cost is only a quarter of silicon solar cells.
Pink is the dye-sensitized solar cells most typical color. Most contain a ruthenium dye, ruthenium red. Mixed with red dye pink metal oxide powder is the most commonly used titanium oxide or zinc oxide, these two metal oxides are white. But researchers at Ohio University created a more innovative materials does have color, they used the metal complex, exploring different particle shapes to enhance the photoelectric conversion efficiency.
This is the first time, researchers using non-single-oxide dye-sensitized solar cell manufacturing. Selected because of zinc stannate is zinc stannate series of complex oxides with tunable properties. This makes the next cut dye-sensitized solar cells possible.
Why dye-sensitized solar cell is pink, not the same as the blue silicon solar cells it? Traditional solar cells showing a blue anti-reflective coating because of the reason. These coatings improve the absorption of green light, green light is the solar energy spectrum, the strongest light. Ohio University researchers have not developed anti-reflective material coating materials.
Color determines the solar cell can capture the wavelength of light, so scientists can modify the color of the special characteristics of solar cell optimization. At present, the development of dye-sensitized solar cells, scientists have used ruthenium red dye to obtain the best results.
If you want to get the best efficiency, you need to take into account access to the voltage and current. Voltage is a potential material to provide energy; current is material to the amount of charge transfer. If you can absorb a very wide range of wavelengths, it will have to sacrifice voltage. If absorbed into the limit of very high energy, high voltage can be obtained, but they have to sacrifice current. Researchers are trying to find a balance.
60 years since the 20th century, since the silicon solar cells have emerged. Since the 20th century, scientists began developing the 90's dye-sensitized solar cells. In dye-sensitized solar cells, dye molecules cover the tiny metal oxide particles, and is stuffed with a thin film. Dye molecules capture light energy and release electrons, and metal oxide particles more like a wire, will be among the electronic transmission to the circuit, but the electronic transfer between the particles may be lost. This is the researchers are designing the merger will be tiny nanowires to transfer electrons directly to the circuit reasons.
They also explore the possibility of using nano-trees - like the shape of nanowires, like tree branches. Which absorb light and transfer the current structure is the best structure? Researchers believe that tree! Leaves provide a large surface area for capturing light, the branches will be transferred to the roots of nutrition. In their dye-sensitized solar cell design, dye particles will provide coverage of the surface area, nano-trees grow between the branches in these leaves, transfer electrons.
Therefore, dye-sensitized solar cells the future growth of a tiny pink will be the "tree", but other colors are also possible. Researchers are studying to work better in the new dyes and dye compounds.
China's solar panels will be restricted by the U.S. tariffs
Recently, news that China exports to the U.S. by solar panels will be up to $ 70,000,000 U.S. tariff "special attention."
The United States Tariff Act to be implemented, a time when the United States on the occasion of solar cell industry malaise. The implementation of this bill would likely harm not only to foreign manufacturers of solar panels, and the United States and abroad will also have solar panels have a great impact on dealers. More serious consequence is that this will further aggravate already tense Sino-US trade disputes if.
December 1 last year, the Spanish energy company in the United States branch of GES USA to the U.S. Customs officials sent a letter in the letter asked the company if you want to import solar panels from China, the United States which tariffs will be levied. Unexpectedly, a ripple, the situation has developed to the United States will impose a special tariff level.
January 9 this year, the U.S. Customs department responded to the letter, said the solar panels from China can not perform tax system. Instead, the panels included with the security and energy-related electronic components, will be levied as import generators and 2.5% of the tariff. 2.5% of the tariff is levied on imported products, the implementation of the standard normal tariffs than the United States a product intended to limit the punitive tariffs on imports is much lower. For example, three weeks ago, the Chinese tires safeguard, the United States to the taxation of tire imports from China up to 35% of the tariff.
However, the implementation of the tariff when the global downturn in the international solar cell industry. By the continued expansion of China and the global solar industry solar panels double impact of falling prices, a lot of solar panels produced a steady decline in corporate profits. Due to overcapacity, and now a way to raise prices to compensate for tariff losses caused by the price accepted by consumers is difficult, but since January this year the price of solar panels has gone down 5 times.
According to the U.S. Department of Commerce statistics show that in the first 7 months of this year, the U.S. import and export of solar panels is roughly equal to the total, of which 605 million of imports and exports 555 million.
By the United States and abroad to form the U.S. solar energy companies insist that the Solar Energy Industries Association, the U.S. government to impose special tariffs on solar panels will result in U.S. imports from other countries impose higher tariffs on similar products.
The U.S. Customs Department's decision into the U.S. solar energy industry in the United States importers and manufacturers of solar equipment in two parts. With China accounting for the increasing share of U.S. imports, the tariff will be the United States following the tires, automobiles, and chicken and then a rise to trade tensions between the sticking point.
American Solar Energy Industry Association, Xi Luoen? Royce Chi (Rhone Resch said the solar panels of some Chinese manufacturers are planning to move to the final assembly line in the United States, so one day to avoid the potential risk of additional duties.
The tariff will be widely applicable for the residential, commercial or industrial electronic systems provide power and energy, solar panels, and built-in solar panels, small light bulbs as a lighting device has been imposed tariffs of 3.9%.
U.S. criticism of the legal profession is not the early detection of solar panel industry, the import tariffs. U.S. Customs and International Trade Bar Association, former chairman of Dewey & Leboeuf is also a partner in Washington's Mel Schwechter said: "For an industry, the use of 8 months time to recognize a duty arising from it is some of the serious consequences of substandard routine. "
Once the U.S. Customs department ruled each company due to "false or false" solar panels imported materials which led to early detection is not already on the solar panels should be included in the non-tax provisions, importers are likely to bear over the past 5 years Import tariffs on solar panels to avoid legal liability.
Chi Rice said in court that the association plans to put solar panels on the list are classified in the generator question.
Lenovo ThinkPad X60 Laptop Review, via lenovo-batteries.com blog
IBM Thinkpad had a solid reputation as a reliable laptop, business-oriented. The X series of ultraportable ThinkPad line, which consists of a single pin design. The ThinkPad X60 is the current incarnation, and our model sports an Intel Core Duo T2400 1.83 GHz, Intel GMA950 graphics and a SATA hard drive 2.5 "(Note:. Is this a model different than the X60, while the light uses low voltage Core Duo L2300 CPU and has no fingerprint reader). It is three pounds lean (depending on configuration) and weighs an impressive claimed battery life is. A station optional docking, second battery or optical drive.
As any ThinkPad owner will confirm, the design is minimalist, a small square, and all black, no highlights or bright, vibrant colors of other models. I prefer this new look for the gray-white plastic on consumers and many businesses low-end laptop. The X60 is not overrated, look at a business meeting or out of small class and very professional.
The X60 has a reading of 12.1 "matte display 1024×768 (XGA), no other options in terms of resolution or brightness. The screen is bright inside and so is not reflected at every level of brightness, but the direct sunlight, in essentially unreadable screen, even at the highest brightness. The poor viewing angles are vertical, horizontal, even if they are acceptable. The screen has no dead pixels and there is little light leakage.
The speakers are always the ultimate test for the design of an ultra-portable designers put the speaker at the last possible point at the bottom in a miniature chamber. If you are deaf in his lap and the sound seems to leave the keyboard. Do not expect much of the sound system and I have what I expected.
The previous notebook had a LG XNote LS50 was with a Pentium M 1.5 GHz My desktop is a Pentium 4 2.66 GHz The X60 blows these two machines of water intended for desktop applications such as Internet, processor text, music and e-mail, not to mention things like virus scanning.
This notebook produces a good amount of heat, especially in the palm rest. The soil is warm, but not much. The X60 keyboard is probably its biggest selling point. The keyboard feels almost as good as the keyboard of thirteen, I’m still at the help desk - rock solid and stable, without hesitation, with a good trip. The fact that no internal optical drive, Lenovo X60 allows for a variety of equipment, including a whole bay have dedicated hard drive for easy removal. The X60 comes with an integrated Intel 3945ABG wireless adapter, it works quite well. My model also includes an IrDA port, although not used. You can build models with Bluetooth and EVDO X60/X60s well, but were not present on this ThinkPad. The X60 comes preloaded with Windows XP Professional SP2 and do not include these records. Instead, Lenovo created a separate partition to restore the computer (although you create recovery discs using a Lenovo utility).
Using the keyboard, the battery is incredible in this team and is a great advantage. I have not had the opportunity to run again, but estimates that it refuses to battery life in Windows 7:45 (in the 8-cell battery) with wireless mode and brightness when the office management applications (something you can actually see happen for the average worker). It is very impressive and is something I see every day by not the rope around (even if the adapter weighs only 0.7 lbs.) The X60 is probably more autonomy, but for those of us who are not required, this amount (which will probably remove a whole day of eight hours, the result of a plug), the battery on the X60 is quite acceptable.
China's development prospects of fuel cell vehicles A
The first round of the 2000 fuel cell vehicle test run after the climax, the world of investment in fuel cell vehicles, from model cars to return to strengthen the construction of basic research. Because scientists sober recognition that fuel cell vehicles to move towards commercialization, will be a need for profound knowledge of the "long-distance running."
August 17, 2006, is the process of development of fuel cell vehicles in a special day, from the CAS Dalian Institute of Chemical Physics and other independent research and development of two fuel cell vehicle demonstration tour, the Xinghai Square in Dalian into a bus has trial run, China's fuel cell vehicles and a significant step forward.
However, compared to a few years ago, "Beyond 2" fuel cell cars and other racing debut the scenes, the fuel cell vehicle in Dalian test run seems much deserted, no media coverage at great length, there is no cause ring experts and the printing of too many people in the discussion. Scientists have looked unusually sober mind: "This is a trial run in Dalian, one of the main purpose is to raise public awareness of fuel cell vehicles, a plain basic truth that, although there has been a global situation of high oil prices, but even a drop of gasoline on the future of the world are not, we can use hydrogen fuel cell car. This is the fuel cell industry for the future by preparing a public opinion. Another purpose is assessment of fuel cells life. "
"Is not a sprint, but a profound knowledge of the long-distance running"
"Hydrogen fuel cell vehicles toward commercialization is not to really sprint, but the profound knowledge of the long-distance running." Chinese Academy of Engineering, and Dalian Institute of Chemical Physics, chief engineer of fuel cell engineering center Yi Bao-lian, talking about the future direction of fuel cell vehicles said with emotion, this is the result of a series of experiments, trials concluded.
Fuel cell is an efficient, environmentally friendly power generation device, which can be stored directly in the fuel and oxidizer in the chemical energy into electrical energy. Bao-Lian Academician, the world's first fuel cell vehicle research and development a climax around 2000, when the United States, Europe and Japan's major automobile manufacturers, all are stepping up development of fuel cell technology, the business community, especially the major automobile manufacturers to see huge market potential of fuel cells, have invested heavily to form alliances and the related fuel cell vehicle research, testing and production. Major car companies, including Mercedes-Benz, General Motors, Toyota and so that the 2004 production of fuel cell vehicles will be able to achieve industrialization. Daimler - Chrysler and even declared, it is expected the price of fuel cell vehicles will be reduced to about $ 18,100 each. U.S. Energy Secretary Peiye accepted in 1998, "New York Times" interview, also make their own wishful projections: the fuel cell into the home, car and other areas of the pace much faster than people's imagination.
Study of fuel cell vehicles on the competition is very fierce. Long-term source of hydrogen fuel cell research in Chinese Academy of Sciences DICP, back in the early 90s of last century, began on the hydrogen proton exchange membrane fuel cell. End of 1996, the study by the National Science and Technology, Chinese Academy of Sciences, the National Natural Science Foundation of financial support, and in the national "Ninth Five-Year" Plan project. In 2000, DICP has developed the first proton exchange membrane fuel cell engine, and with the Chinese Academy of Sciences electrician, the steam group cooperation, assembled out of a fuel cell bus, carried out in 2001 and trial operation. Shortly thereafter, they assembled a 30 kW fuel cell bus. "At that time, many of us are optimistic that the fuel cell vehicle has come to the eve of industrialization." Apart from DICP, the year 2004, China in Beijing, Shanghai and other places, the fuel cell vehicle has been found in the test run, At that time many people also cherish the joy to meet the water broke the baby look like: fuel cell vehicles have been "close to the 'out of the laboratory, the implementation of mass production' of the door."
Dell Inspiron 1520 Laptop Review, via laptopsbattery.us blog
Dell Inspiron 1520 notebook for those who want a stylish and customizable notebook at cheap resource, but the basic features and price, a bit behind much of the competition. Dell also had some problems with the quality control process in some cases, the color system.
The update of the popular E1505 Dell Inspiron 1520 has generated great interest in the mobile community. It has offered a complete design update, the new Intel Santa Rosa platform and the best graphics card Dell never in a notebook of this size have. With this notebook, Dell made a solid entry into the market for 15 performances. Papers "The 1520 tangible advantages over other 15" has only offer the 8400M and 1280×800 resolution as the HP dv6500t, and tends to be cheaper than laptops in the spotlight like the Asus G1S.
Dell Inspiron 1520 Technical Specifications:
Processor: Intel Core 2 Duo T7300 (2.0 GHz/4MB L2 Cache)
Operating System: Microsoft Vista Home Premium
Hard drive: 160 GB SATA @ 5400 RPM
Display: 15.4 Widescreen WXGA (1680 x 1050)
Graphics: NVIDIA GeForce 8600M GT 256 MB
RAM: 2.0 GB DDR2 SDRAM @ 667 MHz (2 x 1 GB)
Optical Drive: 8x CD / DVD (DVD-RW) with Double Layer
Dimensions: 1.47 to 1.65 "(H) x 14.12 cm (W) x 10.59" (D)
Ports / Ports: 1 IEEE 1394 (FireWire), 4 Universal Serial Bus (USB 2.0), 8-in-1 card reader, VGA, S-Video, RJ-45 LAN Ethernet RJ-11 modem, ExpressCard 54 mm stereo output, headphone / speaker and two microphones, digital
The Inspiron 1520 weighs about six pounds and a half and is considered a consumer notebook in general. Equipment, particularly in the form of graphics, will result in 1520 and on all laptops on the market, with the exception of extremely expensive gaming machines that lack of concessions in the life of the battery size and cost. Though this notebook was sent by Dell for the purposes of research and purchased will not, I wanted to address the above issue, simply because there is something of an art to buying a Dell consumer notebook. There are many decisions to make, and like all decisions, they carry with them the potential for regret or satisfaction.
This is the first computer to simply enjoy playing. The finish of the cover is beautiful, almost tactile rubber surface. Dell term because "Micro Satin," and I agree with this description. My first concern was that the material from scratch, but after a sharp scratching with my thumbnail I was unable to produce a mark. Dell currently offers elegant Belkin bags in colors aspect of the new Inspiron party. Personally, I have not bought one because I do not use bags to the Dove / tarragon to match the color of my team.
The screen on 1520 is a color display very inflexible. I had the opportunity to produce a wave of LCD screen with a few decent rotation. WSXGA resolution is ideal for me, I have much room to work with text, but it seems too small. This particular screen looks a bit grainy, but. It is 1 / 4 "light leak is in the bottom of the screen, but I found no dead or stuck pixels.
In 1520, the speakers were moved to the front of the palm rests in the E1505 under the nose of the computer. I would have preferred that they are above the keyboard somewhere, but at least, where they now have less chance to block with his hands that were on the E1505. The speakers are surprisingly loud without distorting too much, and the sound quality is very good. The 1520 is the new Santa Rosa platform, integrating a 800 MHz front side bus features, improved graphics and new features integrated Wireless-N How many other Dell notebooks, the 1520 features MediaDirect boot that has enabled him to directly into MediaDirect without loading the operating system. The noise is average for a laptop. This is a soft hum, but nothing I found offensive. Even if the fan is running, it is actually stronger than background noise. The keyboard material seems to be the same as that used for the M1210 and has a good grip with it, not softer Inspiron keyboards of the previous generation.
Dell Inspiron 1520 Laptop Battery
Battery life will appear in force under the load of the CPU performance settings are about three hours with the 9 cell battery. You could probably extend the four hours or more by disabling wireless, lower screen brightness, and less intensive applications. 9-cell battery extends beyond 3 / 4 "from the back of the computer, but that does not seem particularly remarkable given the size already in the laptop.
Under fairly heavy usage, such as the activity of many hard drives, wireless and the screen goes to full brightness, the battery could run for almost three hours. Very easy to use and a poor display, but wireless is still ongoing, resulted in an extra hour or more. I expected a greater inequality, since my use of the two tests was at opposite ends of the spectrum, but I have used Bluetooth to test the light, and both times seemed fairly strong for a machine of this performance. With a little tweaking, I’m sure others could squeeze more battery life 9 cell.
Dell inspiron 1520 laptop battery is a high quality rechargeable replacement battery which can 100% compatible with the OEM inspiron 1520 battery which can works with a lot of dell notebook laptop computer. dell inspiron 1520 laptop batteries are warranted for a full year to ensure your complete satisfaction.
