A variety of candy to be chosen-Yixin Foods

What is called candy?This words you maybe be very familiar with it,but you will also feel it as a stranger.As for candy,it includes lollipop,chocolate,gum,jelly and so on.Please see as below brief introduction.
Hard Candy Lollipops
Lollipops are candies that you put a stick through. So their shape looks like a circle with a line through it. Usually in American or European countries, hand-made lollipops are bright coloured and disk-shaped. But a lot of the factory made ones are smaller and spherical.
Chocolate
Chocolates are perhaps the most classic and popular of all the candies. It is made from the ingredients cocoa, milk and sugar. It comes in all sorts of shapes and forms: blocks, bars, balls, toffee, ice cream etc. The reason it is popular (besides its splendid sweet taste) is the belief that by eating chocolate, you get a sensation of falling in love (which is why we receive it on Valentine's Day!).
 Fruity Chewing Gum
Chewing gums have a lot of flavours: peppermint, strawberry, lime, blueberry etc. And new sugar free ones have been roaming the market in recent years. Although dentists propose that chewing sugar-free gum is actually good for your teeth, a lot of public places (especially schools) still reject chewing gums mainly because it leaves a lot of mess if not thrown into the bin.
  Fruit Bubble gum
Bubble gums are much the same as the chewing gums mentioned above: they are both lollies that you keep in your mouth but do not swallow. But bubble gums are significantly less dense and usually come in larger pieces. This is so that you can make bubbles out of them. They are a great fun at parties.
Colorful Jelly beans
They are those colourful, pretty and sweet little beans that kids really love. Often different colour would signify a different flavous. Thus there is all sorts of discoveries that you can make in a packet of jelly beans.

Heat dissipation application of graphite powder in LED lamps

The features of graphite powder are soft, dark gray; oily feel that can contaminate the paper. In the isolated oxygen conditions, the melting point above 3000 ℃, is one of the most resistant minerals. At room temperature, the chemical properties of graphite powder are relatively stable, insoluble in water, dilute acid, dilute alkali and organic solvents; different high temperature reaction with oxygen to produce carbon dioxide or carbon monoxide. It only oxidizes with fluorine and simple carbon in the halogen. Graphite powder is easier to acid oxidation. Besides, it can also react with many metals to form metal carbide, which can be smelted at high temperature.
Graphite powder is the necessary raw materials for industrial production and application. The application of graphite powder has begun to move to the more high-end, which has launched a variety of applications, such as in electronics, new energy, high-end manufacturing, medical and other fields. LED lamps is the environmental protection and energy saving lamps recent years that LED lights cooling is the need to solve the problem of graphite powder.
LED lamps and lanterns of the poor heat can lead to damage to power, light failure accelerated, shortened life and other issues, LED lighting system performance is always the top priority, metal materials in the application of LED cooling difficult to process, energy consumption, density is too large, conductive, easy to deformation and difficult to recover waste and many other issues, and graphite powder material will not be such a problem, graphite powder plasticity is good, easy processing, and has excellent high temperature, thermal conductivity and other properties. Graphite powder can be processed into the graphite heat sink, the heat emitted by the lamp will be absorbed through the graphite heat sink, and even to the surrounding heat, graphite powder and plastic can also be made into a heat sink, cooling the cooling cup and cooling shell and so on.
There are many cooling performance in the application of LED lights, including LED chip packaging components, LED optical lens, light scattering components, efficient cooling components, light reflection and light diffusion board. Graphite powder of high-end products plays an important role in the solar transparent electrode, thermal materials and touch screen and other fields.

Recently, alloy lithium-containing negative electrode materials (including silicon, germanium, tin-based anode materials) with higher lithium capacity have become the most promising alternative materials for future graphite-based negative electrode materials. The structural design of these materials at the nanometer scale can effectively improve the electrochemical cycle and magnification performance of these materials, and fully demonstrate its promising application prospect in the next generation high performance lithium ion battery.
Germanium has a higher electrical conductivity and lithium ion diffusion than silicon, so germanium is a powerful candidate for high-power lithium-ion battery anode materials. At present, the researchers try to prepare a variety of germanium nano structured materials to improve their electrode performance. Korean scholar Park and so on to obtain zero-dimensional hollow germanium nanoparticles and three-dimensional porous germanium nanoparticles, showing better cycle performance.
Also, researchers at the University of Munich, Germany (TUM) and the University of Munich (LMU) have discovered a new method of making thin, solid, and porous semiconductor layers using nano structured germanium materials that are expected to be used to develop portable solar cells and batteries electrode.
This material is very suitable for small, lightweight and soft solar cells, or to improve the performance of rechargeable batteries electrode. Scientists by integrating the amount of organic polymers in the pores of germanium materials can be tailored to create the electrical properties of the symbiotic mixture. This design not only saves space, but also create a large interface surface, enhance the overall performance. In the porous porous germanium nanometer film filled with the right amount of organic polymer, making it a hybrid solar cell。
Manufacturers around the world are looking for light weight, sturdy materials, and portable solar cells. So far they are mainly used for organic compounds, which are sensitive and have a relatively short life span. Heat and light decomposition of the polymer and result in reduced performance. The thin but strong germanium mix provides a real choice.

How to choose the right optical module

With the rapid development of information technology, the application of optical communication has become more and more popular. With the advantages of large capacity and high-speed transmission, Fiber Optic Transceiver Modules is playing a more and more important role. Where there is fiber, the optical module is needed, and the selection and purchase of the optical module has become the focus of the front-line engineering technicians or purchasing personnel.
There are many types of optical transceivers on the market, often dazzling. So, how to choose the most suitable module in many different speed, different packaging, different functions of the Optical Transceiver Module? We will give you some tips.

◆ Choose the module based on your usage environment
How fast the speed of transmission you need? 155M, 1G, 10G or 100G? The higher transmission rate means higher cost investment. For example, the application environment of FTTH, it's enough to use about 1G speed products for current bandwidth. It's not necessary to choose 10G products with more money.


◆ Transmission distance
The common optical modules are divided into short distance (300M-2KM), middle distance (10KM-40KM), long distance (>40km), The farther the transmission distance, the higher the technical and technological requirements of the optical module.


◆ Compatibility
When purchasing optical modules, need to confirm whether it can be compatible with your devices. Common switch brands like CISCO, HUAWEI, H3C, Juniper, D-link, HP, IBM, dell, Mikrotik etc., modules need to be tested compatibility before shipment. Before purchasing, it is best to confirm that it can be perfectly compatible with the corresponding brand switch.



◆ Select the original one or compatible one according to the budget situation
The original module is reliable but the price is too high, compatible module is cost-effective, comparable to the original module. Different users need to make specific choices according to the budget.

◆ After-sale service
Although the optical module is a mature optical communication device, most manufacturers' products are stable and reliable. However, there may be some problems in the use after purchase, so choose the vendors who have after-sales service and technical support are more secure.

Auto Bumper Repair From Our Auto Bumper Factory

All of use love to have automobiles, but not everybody gets the possibility of having one. That is why when you get the chance to have one; you do every little thing to look after your vehicle by eliminating accidents as much as possible. However, there is still an excellent possibility that you have harmed the bumper on your vehicle at some point in your driving occupation. Your bumpers are the most discovered parts of your car. They are the most likely to be harmed and bringing them to our Auto Bumper Factory. There’s likewise an excellent possibility that something much even worse than getting your bumpers harmed has occurred to you. You most likely have paid too much by up to twice to get those bumpers fixed to specific auto service center. Really, body shops have 2 options to bumper repair – repaint the whole bumper or replace it (if the bumper has been cut, dented, or misshapen).
There’s one option that they nearly never think about – fix and repaint just the area that has been harmed. The body shops were more than pleased to toss bumpers that were 90 % brand new because they might mark up the expense of the new bumper to the customer. And they were just as happy to paint the whole bumper for small scrapes and scrapes covering just almost 20% of its surface area since the paint, guide, labor were all marked up also. In sum, the method of body shops is to make tasks as big as possible due to the fact that bigger tasks yield larger profits, and it’s not the client that’s forking over, it’s the insurance firm (don’t fall for that– you pay and then some in time when they increase your rates gradually). The typical bumper repaint is about $450. An upgraded replacement is generally $750 or more. There exists a sub-industry that vehicle dealers utilize but the general public is primarily oblivious of, the area repair business. Auto bumper repair in Rockford has area repair techs that focus on this kind of repairing work.
They can enhance the shape of, refill, recolor, and re-clear nearly any bumper that doesn’t have damages done to the tabs that attach it to the vehicle (that is around 80 % of bumper damage, FYI). In contrast to what auto body shops will inform you, bumpers can be fixed, and just the location that has been damaged can be painted. This does need some ability. The painter must know ways to appropriately scuff beyond the broken location, assimilate the paint, and use the clear coat so that the repair is undetected. What is the ordinary cost for a corner scrape, the most typical of all repairs? The fundamental expense is roughly $250 or more. The greatest perk on this kind is most spot repair techs are mobile. That means they concern your home or office. A bumper could be primed, painted, sanded and healed within an hour or maybe more. Consult your neighborhood automobile dealerships if they understand of a firm that does an auto bumper repair in Rockford. These men must be a lot of aid to you.
