New Tool for MOCVD Carrier Characterization

k-Space Associates introduced the kSA Emissometer, its newest addition to an extensive line of in-situ, in-line, and ex-situ thin-film analysis tools for semiconductor, surface sciences, and photovoltaic industries. The new tool provides MOCVD fabs with essential wafer carrier characterization, such as emissivity uniformity and defect identification.

MOCVD fabs usually rely on subjective human tests to inspect the quality of wafer carriers. The kSA Emissometer has the advantage of high resolution carrier emissivity mapping and detection of defects and microcracks that aren’t visible to the human eye. This tool provides full quantitative carrier maps in 10 minutes.

The kSA Emissometer also provides fabs with systematic carrier data that can be integrated into their quality control processes as well as a go-no-go decision on carrier use and quantitative determination of the carrier emissivity, allowing for temperature set-point adjustments for individual carriers.

First International Airport in the World Uses Solar Panels

First International Airport in the World Uses Solar Panels

Awareness of environmentally friendly energy use today is increasingly flourishing. Accompanied with the low price of renewable energy sources such as solar panels one of which also contribute to the renewable energy campaign. Example one concrete step movement use of renewable energy sources conducted by Cochin International Airport in southern India. Seventh busiest airport in India was crowned as the first international airport which is 100% of its electricity needs met by solar panels.

To meet the electricity needs of the airport, the airport management pointed to a German company, Bosch, to build a solar power plant on vacant land measuring 45 acres located near the international cargo terminal of the airport. With a total of approximately 10,000 solar panels are used, this self-contained power plant capable of supplying 48,000 to 50,000 kilowatts of electricity to meet the electricity needs of the airport each day. Even the amount of energy is still surplus and still able to support the needs of the electricity network in the area around the airport.

Construction of solar power plants this independent cost US $ 9.3 million, equivalent to 121 billion rupiah. With the cost of the airport management hoped would never buy electricity from its India up to six years into the future. In addition, the solar power plants contributed to reducing carbon dioxide emissions of 300,000 metric tons of coal-fired power plants of up to twenty-five years into the future.

Recent discovery dwarf planet in orbit farthest So Far

Recent discovery dwarf planet in orbit farthest So Far

Since Pluto is no longer acknowledges the real planet, has several times found “dwarf planet” Pluto have similar orbits beyond Neptune. Dwarf planet is a term for a planet that does not meet the third criterion of three planets criteria set by the International Astronomical Union.

One interesting thing is that apparently in addition to the dwarf planet Pluto, beyond the orbit of the planet Neptune lies a giant orbit space contains many objects that scientists have nicknamed him the Kuiper Belt. The Kuiper Belt is an orbit of ice in which there are few objects of space that has been identified by scientists as a dwarf planet, like Eris, Haumea, Makemake, Sedna, Quaoar, 2007 OR10, and of course Pluto which has been first discovered in 1930 by Clyde W. Tombaugh. Even recently identified a new dwarf planet that orbits super far exceeds other dwarf planets that travel is about 700 Earth years. Planet is still named interim RR245 2015 is estimated to have a diameter of only 700 kilometers, there are still much smaller than the dwarf planet Pluto has a diameter of 2371 km.

The discovery of the dwarf planet 2015 RR245 which was first identified in February, is one of the results of surveys, titled Outer Space Solar System Origins Survey (Ossos). Ossos so far been detected at least 500 space objects in the Kuiper Belt Area. However new RR245 2015 are identified as a dwarf planet. Astronomers will continue to observe planets that orbit will reach its closest distance to the sun in the year 2096, in order to obtain data that is more accurate.

Nuclear Reactor Made From Water

Reaktor Nuklir Berbahan Baku Air

The good news for the provision of alternative energy sources in the world. Fusion energy is likely to be soon used in small-scale power generation. Fusion energy used is generated from a variety of chemical reactions involving water. This means that humans will get one more environmentally friendly energy sources and cheap. A study conducted at the University of Gothenburg is trying to produce generator-powered heaters and electric generator energy of nuclear fusion which involves water as basic materials.

Nuclear fusion energy is the energy that results from the union of two nuclei to form a larger nucleus. The unification of the two nuclei into one atomic nucleus releases a huge amount of energy called nuclear fusion energy. For those of you that had not been aware of the existence of nuclear fusion energy in the universe, the stars in the sky caused by the release of energy from nuclear fusion “star body”. Hydrogen bomb explosions also occurred due to the release of nuclear fusion energy. We know that the hydrogen bomb is one of the most powerful bomb ever made by man. This indicates that nuclear fusion energy has enormous power.

Research new types of nuclear fusion process is capable of producing nuclear fusion energy free neutron, and also capable of producing heavy electrons (muons) because this energy is produced from nuclear reactions taking place in the ultra-dense hydrogen atom (ultra-dense heavy hydrogen).

As described above, the heavy hydrogen is found in abundance in the water, both rivers and oceans. Heavy hydrogen can be extracted without the process is too complicated. For large-scale reactors may be required handling radioactive heavy hydrogen (tritium), but for small-scale reactors it is less needed. Process-based nuclear fusion of deuterium is also capable of producing very large electric energy in a short time. Reminded once again, this fusion process does not produce neutrons that are harmful to living organisms and can produce muons, heavy electrons, which have a rapid onset and can be instantly transformed into ordinary electron. This means that heavy electrons produced will soon re-cycle itself into ordinary electrons and does not produce a new particle that may be harmful to the environment. The most important thing is not a large-scale reactor is needed to facilitate this process of nuclear fusion.

Solar Panel Technology Revolution

Solar Panel Technology Revolution

A revolution in technology alternative back unsolved. A group of mechanical and Australian scientists who are members of the Victorian Organic Solar Cell Consortium has announced that they will soon be marketing a new technology in producing solar panels. The technology they create does not require a complicated way to produce solar panels, all they need is a printer! Yes, a printing machine that will quickly and cheaply can print solar panels onto the surface of any object, especially plastic! Naturally this innovation will decisively, sooner or later, push down the price of conventional solar panels are quite expensive because the manufacturing process is more complicated.

That this new technology can easily print solar panels directly on the sheet of plastic or other material. In fact, it can also be printed directly onto electronic equipment sorts of laptops and smartphones, so they get a renewable energy source at any time.

Print it out on a plastic sheet is approximately equal to the process of printing banknotes. Connect it with other electronic equipment as well as easy as installing the battery. It’s very cheap! The interface is also quite different from the conventional silicon solar panels. More detailed printout solar panels that will appear transparent, thus making it very suitable to be applied to building homes and buildings.

The next task is to improve the efficiency of the panel. We should be able to create a ‘printing ink’ which is able to absorb more solar energy. We are sure to be able to do in the next few years.

Hydrogen Cooling Systems in Power Generator

Hydrogen Cooling Systems in Power Generator

It is undeniable that an electric generator is required to have an excellent cooling system to remove heat created therein. If the heat in the generator is not immediately removed, he will directly damage the generator itself. Excessive heat can damage the coils in the extreme rotor, stator, it will even burn components of the generator.

Hydrogen gas is the best choice to replace the air as the cooling medium generator primarily on large-sized generators. Hydrogen chosen because its characteristics were excellent when used as a coolant, call it a high thermal conductivity (0.168 W / m · K), its density is very light, and also a high specific heat. With these characteristics, making hydrogen 7-10 times better than air conditioning if used. This can be likened to generate the same electrical power, air-cooled generator will be sized 7-10 times greater than the hydrogen-cooled generator. Therefore, for large-sized generators, hydrogen cooling systems will become more economical than using the air conditioning. Actually, helium gas has good thermal conductivity as well (0.142 W / m · K), but because the price is much more expensive than hydrogen, then it is not used.

Generators are formed from millions of winding wire arranged in a coil on the two sides of the different sectors the rotor and stator. The coils will generate very high heat during generator operation. Hydrogen as a coolant to flow generator will envelop these coils, absorbing heat, and throw it in the cooling heat exchanger. There are two types of hydrogen in the generator cooling system commonly used is hydrogen cools the generator rotor stator at the same time, and generator with hydrogen cooling for the water on the rotor and stator side. Generators that use hydrogen coolant in the water on the rotor and stator usually large and Megawatt electricity generating over 500 MW. Read more

Innovations from General Electric

Innovations from General Electric

A quite revolutionary innovation made by electricity giant General Electric, known as GE. GE is currently conducting research to build a mini power plant the size of a desk, but was able to support at least 10,000 households. Mini turbine is mentioned only a size ten times smaller than the steam turbine with the same energy output capabilities.

A unique feature of this turbine is the driving fluid are not uncommon. Not water vapor, not wind nor water! The turbine uses the fluid carbon dioxide as an energy transfer medium. Carbon dioxide is heated to 700 ° C at very high pressure to supercritical prior to entry into the turbine. Carbon dioxide out of the turbine is cooled and the pressure is increased again before going back past the same cycle.

Technology use of carbon dioxide into various key advantages of this turbine. First advantage is their small size, outsize steam turbines up to ten times smaller. From these advantages alone deliver the turbine further advantage to the startup much faster than the steam turbine. Turbine CO2 only takes one to two minutes to reach full rotational speed, compared with the steam turbine which takes up to half an hour to turn it on. In terms of efficiency, this new type of turbine is able to achieve up to 50% thermal efficiency, which is certainly far enough steam leaving the turbine efficiency is only able to achieve 45% only.

To date, still building a small-scale CO2 turbines capable of generating power up to 10 Megawatt. But planned to be built turbines with power up to 33 Megawatt, power highly enough to support approximately 10,000 households or practically equivalent to a fairly large city. Explained that the main thermal energy sources that will be used later is solar thermal, nuclear or even burning. Technology uses molten salt heat storage will also be used so that the heat from the source can be stored for use at a difficult time as a heat source in winter.
