A new method of manufacturing printed organic solar cells, ultimately brings the model has the advantages of low cost,solar panel 2012dab4c51ck cheap price of the flexible solar panel.
The job of leading the Alan Haig ( AlanHeeger ), he and Guillermo - Baz ( GuillermoBazan ) shared the Nobel Prize for chemistry in 2000, is because the development of the conductive polymer, is easy for manufacturing plastic solar cells and organic light-emitting diode. Haig and Bazan are California University at Santa Barbara ( UniversityofCalifornia, SantaBarbara ) Professor of chemistry.
A higher magnification of transmission electron microscopy images, display planes stacked small molecular solar material lattice fringe,
Polymer solar cells efficiency is less than that of silicon solar cells, but it is cheaper to preparation. Organic material either with the polymer, or by the so-called" small molecules", i.e. low molecular weight organic compound, can be made into ink, a large area of printing. They are light and flexible, is expected to carry some applications, such as a roof mounted or solar battery, charging for portable electronic devices.
Use Bazan to design a novel small molecule, Haig made of a solar cell, can put according to the upper6.7% of the energy of sunlight into electric energy. Bazan predicts, within a year to achieve 9% efficiency. Although laboratory testing efficiency often far higher than the production of battery efficiency, however, this will make these materials may be comparable to the best on the market of polymer solar cells.
Up to now, improving organic solar cell performance and cost,baby clothes wholesale ukogkewe25dwe the bulk of the work has focused on the development of new polymer materials.
Bazan is taken, combine theory and experiment, the development of new small molecule materials. He first to optimize its electrical performance, making this molecule can support required by the high current and voltage, have solar power. Particularly difficult is to create a small molecular material, made good films; while the polymer is very long, and twisted into a stable films, however, small molecule is not easy to produce the plane film preparation, is a solar battery is needed for film.
In experimental platform with many times before, the Bazan group proposed an appropriate small molecule and process, can be prepared by high efficiency small molecular solar cell. This work has been in the" natural" magazine introduction material. Bazan is expected to adjust the material design, further improve the performance of.
Haig says, in the past, he was not seriously small molecular solar energy materials, because the performance is very low. " Other people have been using small molecules, but the performance is far below the polymer, " he said.
However, in the energy market, it is difficult to make organic solar cells become real competitors, especially because the silicon cells become more cheap. " Performance and service life have yet to reach that step," Yang Yang ( YangYang ) said, he is the University of California at Los Angeles ( UniversityofCalifornia, LosAngeles ) Professor of materials science and engineering. Yang Yang is studying the polymer solar energy materials, in his company, Mel ( Solarmer ) is a solar energy company, he also in his academic laboratory study of small molecular solar cell; his goal is the laboratory made batteries reach15% efficiency. But, said Yang Yang, Santa Barbara's work is very important, examples of promising small molecular solar.
As these materials in the market operation, Haig said," is too early, it's hard to know," but he thinks, efficiency has reached a considerable level,personal computer remote 2012 and the solar energy materials promising. " Now, we should be taken seriously, " he said.

LED lighting in the second half of the year is getting better and better
This year China five one holiday TV sales than expected,Health Supplement dcb4a51kk causing LED industry to LED backlight market perception also tends to be conservative. The busy season is not doubt again, however, and adjusting mechanism of PIDA points out, this year is expected to be on LED lighting to boost the momentum, and estimated the overall Taiwan LED value would increase in the second half of the year, total production value of annual growth rate of10%, look reach NT nearly 200000000000 yuan period.

LED lighting demand of second half of the year off significantly, to be held in June in the Guangzhou Lighting Fair, to be about to join the LED manufacturer currently has also set a new record, the scale will also have the chance to exceed Hongkong Lighting Fair; in addition, the LED exhibitors in Taiwan photoelectric show warm degree was higher than that of the panel and solar photovoltaic.

It is understood, to participate in Taiwan photoelectric exhibition and foreign manufacturers including Nicha, Cree, Osram, lighting, Seoul semiconductor, Lite, Delta, this station, Edison, crystal, can a round, Thailand, industrial, and is different from the past, to LED own-brand exhibiting lamp factory has increasing trend.

According to PIDA LED points out,2011, total production value of industry of annual growth rate of3%, while the LED lighting market by domestic price change of LED lamps, increased demand, coupled with the digital TV broadcasting television drive dress up LED increased, while LED backlight module will drive GDP growth this year, the Taiwan LED overall value in the second half of amplification.

Fuji economic report points out, Japan since the nuclear disaster power supply tight, to accelerate the replacement of LED lighting, LED lighting in2012occupies the whole lights are type38%, and estimates of up to 244700000000yen, and the continuous promotion of the twelfth five-year plan to install street lighting installed, is expected in 2012a total of 1220000light, T8 LED lamp Taiwan 's domestic market, coping oil electric double up, economy of energy saving performance guarantee project ( ESCO ) model to promote Taiwan set LED street lamp project, is expected to dress up326000 lights above LED lights, drive the NT4481000000 yuan output value.

Vaccination, commonly known as Dafangyizhen, is to protect the child less or not by some infectious diseases is one of the effective measures. Now with the vaccination knowledge popularization, timely vaccination parents have been increasing,Yun Zhibut many people still have a superficial knowledge of knowledge of vaccine.

Some parents think that as long as the number of vaccinated, the baby will be less sick; also some thinking that the vaccine is bacterial, virus made, with a toxin, so less is more. Should should not let children vaccinated? Experts think, parents learn more vaccination information and knowledge, in order to give their children more protection.
In children in good health at the time of inoculation
Due to the use of vaccines, many have a serious threat to infants,wholesale baby clothes suppliers children and even adults the life and health of the infectious diseases have been substantially reduced or extinction. However, no vaccines may lead to adverse reactions. In many cases, adverse reactions are mild, a few days will disappear.

Gongshu District CDC deputy director of introduction to not fly, vaccination of children against parents must clear the child body is it right? Well, not to postpone vaccination. The day after inoculation, don't take a shower, don't let the child is too tired. Allergic constitution person, should be timely to reflect the doctor. Very few children after vaccination may be a high fever, the doctor may have a look, give symptomatic treatment.
The following is not in this period such as vaccination: children are have a fever, suffering from acute infectious diseases, asthma, rubella, eczema and other disease or heart disease, nephritis and hepatitis and other diseases, do not hit precautionary needle. A history of epilepsy and drug allergy history not to vaccinate children. Details in the community to parental vaccination notice are clearly shown, parents must be read carefully.

After inoculation, there is little children might have some mild local swelling and pain, if the baby high fever, can take anti-fever medicine, do physical cooling, eat some nutritious and easy to digest food, feed water and to observe the child's condition changes. Severe abnormalities in response to timely medical treatment.

People for some diseases and no effective antibodies, if not vaccinated,baby shoes wholesale not only can put themselves in danger of being infected, but also to the surrounding friends pose a threat to. " We can't because of concerns about side effects and do not give children vaccinated, it will give up eating for fear of choking, resulting in many disease stage a comeback, but have more serious consequences." I wish the director says, so parents need to do is, as far as possible in accordance with the provisions of national immunization program for vaccination, expanded immunization program vaccine according to actual condition chooses to children, protect children from infectious diseases.

The song is represented by IBM squatting type spring membrane keyboard, this time in286very active keyboard full name is buckling spring bend axis of the spring film type mechanical keyboard ( buckling, spring means the curved spring ) it and the mechanical switch keyboard, there's a big difference between.PC remote control Some say by typing it like in the piano music feeling, it is sturdy and durable, not easy to be damaged, let them even normal life has been to, but still be in circulation on the market.

Each layer of the double-layer structure is the key cap is spring,If I am rightspinach008 the 5 layer of the film sheet in the metal disk is composed of a switch circuit, an upper black piece is made of rubber used to protect film, in black rubber piece, is a layer of carbon membrane, the contact is a good print. There is another layer of the printed circuit and the contact, but if two piece placed directly, each of the contacts will be in long-term communication.

When you press the key for nearly 3/ 4 of travel time, spring reaches the limit of compression and bending moment and hitsblackcurrant the wall makes a click sound ( this and other mechanical switch keyboard switch contact sound completely different, really admire IBM guys creative ah ) at the same time as the angle changes make the following module through principle of lever pressing, exposure to the thin film switch circuit. To make this ingenious design is the key for realizing the internal structure of the angle ( no wonder people evaluate the small spring pool countless designers wisdom ).aprico

This keyboard is due to the high cost,date in order to control the PC overall cost, has now been discontinued, but due to its inability to replace the hand,bluetooth keyboard and excellent quality, so the market is still very much alive.
