Is this the deepest Hole in the world? Its depth is equivalent to the height of the Eiffel Tower

Scientists have found Chinese State claims Hungarian hole ground or giant, which has a depth range of approximately 300 feet or 987.

Kitingan was more than 4 meters height high Eiffel Tower in Paris, France.

From the website "the daily mail", Tuesday (26/07/2016), a hole that had given the title ' Dragon ' as the researchers found hole Friday in the South China Sea.

After measuring, Hungarian Hungarian researchers claimed the deepest in the world in the Bahamas who beat the depth reached 663 feet or 202 metres.

The daily mail wrote "underwater sinkhole located at 16.31 degrees northward and eastward 111.46 degrees below the surface of the South China Sea." In addition to find the Hungarian, a researcher in the country that there are 20 marine species that live inside them.

They also send divers to ensure species out there, but these divers gave up because the sea was too deep.

It is estimated that there are still other types in a giant SINKHOLE. Some have offered 200 metres reaches.

I tried to measure the depth of the sinkhole divers but reach 39 metres. And then it goes because the hole too deep.


There are potential new light harvest Bandgab narrow quantum limited mechanisms


Researchers have found the first time quantum confined bandgap narrowing mechanism so you can easily extend the UV absorption of quantum graph points and TiO2 nanoparticles within the visible light.

This may allow him to design a new class of composite materials for light harvesting and optoelectronics.

Dr Chen says Lee, Associate Professor in environmental engineering & Queensland micro and nano technology center, will apply real life high efficiency solar cells paintable and purify water using sunlight.

Says: "where there is an abundance of Sun we can brush on this nanomaterial to harvest solar energy create clean water."

"This mechanism can be very important to harvest light. What is most important to come up with an easy way to accomplish that, make UV absorption of visible light absorption becomes narrow bandgab. "

Visible light makes constitute 43 per cent of solar energy, compared to only 5 per cent owned by UV.

Substantial efforts have been made to improve absorption in Titania visible light or visible light sensitive materials in General.

Methods used in Titania, including doping metal ion, carbon and nitrogen doping doping and hydrogenation typically require strict conditions for the modified TiO2 like high temperature or high pressure.

Innovative paper published in chemical communications "," a "Royal Society for Chemistry, the researchers noted that when mixing TiO2 particles with quantum dots Graphene, the resulting compound absorbs visible light by quantum confined bandgap narrowing.

"We were really excited to discover this: when two UV absorption of quantum dots are seen Graphene and TiO2, were mixed together, they began to absorb in the visible range, and most importantly, can be tuned in bandgab quantum dots size Graphene," says Dr Lee.

"We named the phenomenon ' narrow bandgap ' limited quantity this mechanism can apply to all semiconductors, quantum points when combined with Graphene. Flexible adjustment of bandgab very desirable in semiconductor-based devices. "

This work has been selected feature in front inside cover of "chemical communications. Also has emerged a group travel from Graphene quantum dots recently in nanotechnology.


Two Planet Seems Like Eart Has Been Founded by Scientists, Was There Alive?


Santiago-recently, scientists discovered two ' world ' that can be inhabited, and the structure of the rock like Earth.

It makes the space researchers believe that opportunities to search for life on planets other than Earth.

Citing "the guardian", both planet Earth (21/07/2016) is said to be close to the solar system-yet light year 40-orbiting a star called ' small ' Monk-1.

The star looks reddish colored, infrared induced that appear in the lower part of the spectrum.

Second planet ' caught ' when transfer-rare occurrence-crossed paths at the same time in front of the stars.

Pair the planet clearly visible from the Hubble Space Telescope, in orbit.

"You only have 45 minutes to monitor on an ongoing basis. We are very fortunate to align the planet altogether, said a bystander at MIT, Juliette de wit.

After having found the planets in 2016, researchers noted that displacement would soon double in two weeks.

Then she makes a proposal rashly, in less than 24 hours. Just by looking, binigamatan agreed to proceed.

Then, using a telescope, systems experts were watching closely the movement of the planet.

They saw a flashing star light during the swoop, during his travels through the Earth's atmosphere.

If you enlarge a glancing blow, it will cause the impact of atmospheric gas composition, with great clouds of glowing revolves around the Earth.

On the other hand, assume a more versatile wavelength, then the atmosphere is more dense and thick-like Earth's atmosphere-will form.

"We should be able to see a big difference over the amount of light that is blocked by the atmosphere. Such a great atmosphere and spread on Jupiter or Neptune, said de wit.

The researchers said, "but we don't see much difference, it means opportunities are the same as the planets Mercury, Venus, Earth and Mars,".

Although the two planets ' Rocky ' aliens orbiting the star, have a stark difference from Earth and the other planets.

De wit said couples on the planet ' associated ' with each other. So facing the Sun, while others dwell in the shadows-like Moon and Earth one planet.

"It would have been ' world on the planet ' water, something that doesn't exist in the solar system. Or it could just be a climate dominated by oxygen, said de wit.

Each of these planets might be atmosphere like Venus, where carbon dioxide painted sky; Earth, with thick clouds and a mixture of nitrogen and oxygen; or Mars, the atmospheric mixing with the solar wind.

"With the help of tools that are more sophisticated, can make scientists describe the elements and molecules that dominate the Earth's atmosphere," explained de wit.

The research team hoped to be able to continue the search for three other planets in the system to a monk.

"I will examine some 70 stars and continue to search for other planets.

The research was conducted using a telescope monk in Atacama, Chile. Lesson design monk equipped with large object model and infrared (speculaas), which can be 500 star systems with a focus on light and small stars.

De wit said, using a new telescope-costs 400 thousand us dollars or $ 5.2 billion-can create detailed records of planets and stars.

So far, NASA scientists discovered more than 1.200 planet outside our solar system, including 500 Rocky planet.

The three planets that have been found in the past 18 months makes hope grow, scientists find planet Earth, which can be inhabited, not too close to the Sun, and has a surface of rock and water.
