Nanotube Coating – The New Breakthrough Enables Novel Laser Power Meter!

As one of the countries that have the most advanced army weapons in the world, The U.S. military is always tried to invent and improve the army weapons into the highest level. Recently, the U.S. military had declared a new high-power laser system. This incredible technology can be used to defuse unexploded mines more quickly and easily, thanks to a novel nanotube-coated power measurement device. According to the news, the brand new Nanotube coating laser power meter is developed at the National Institute of Standards and Technology (NIST). Before that, the developers have done various experiments on it. Did you know that light focused from a 10kW laser is million times more intense than sunlight reaching the Earth? This device will be used to measure the light emitted by 10-kilowatt laser systems. The new power meter is extremely smaller compare with the previous ones. It’s only about the size of a crock pot! The new power meter is slightly different from other power meters, as laser light is absorbed in a cone-shaped copper cavity. A spinning mirror will be used to direct the light over a large area and distributes the heat. The coating absorbs light and converts it to…

Today's Biggest NASA Challenges

NASA with its several efforts in aerospace achievements has been constantly targeting several challenges before it and there are seven main and big challenges before them currently. There are several technical constraints which are acting as obstacles for execution of several successful projects. Let us see them one by one. Once such is the lunar Regolith excavation. It was held during the second and third of august in the campus of polytechnic state university in CA in San Luis Obispo. Let us see now what the challenge was exactly. The challenge was connected with the lifting of the lunar soil which is otherwise known to be lunar Regolith. Building an excavator which would help in the roving of and that could excavate as well as navigate and also help in the transferring of hundred and fifty kilograms of the simulated lunar Regolith in a bin that would be used as a collector within a time span of just thirty minutes. The need is that moving the lunar soil from one place to another will be very important in case of any construction on the moon. Even the processing of the resources would be requiring the transport of the Regolith. This…

What artificial intelligence can do these days?

Artificial Intelligence is part of computer science program which deals in making machines behave and perform operations which a human being can perform. People have been trying to make machines behave like human for a very long time and today with the help of advanced computing people are able to achieve it. Artificial Intelligence in short is termed as AI. There are various departments where Artificial Intelligence can be extensively used. Out of all departments defense is one area where artificial department has been widely used. Gaming is another department where artificial intelligence is getting used. Gaming is a very popular among youngsters and when these machines starts responding to human being’s request people get more exited. There is both advantage and disadvantage in Artificial Intelligence. One of the great advantages is that by using artificial intelligence technology we can make machines perform human being activities thus minimizing human labor. You can use machines to perform work which human being found difficult. Now a days human being can sit in their office and control their house computer. Not one researcher can invent an artificial intelligence systems, it takes years to build a proper and advanced artificial intelligence system.

Self-repairing materials – car self repair

The vast development in the field of Nanotechnology has made it possible to develop a material, which can help in the process of self-repair to any damage caused to the car. The damage might be in any form such as the scratch, which has been formed in the body of the car. This self-repair process is analogous to the self-healing mechanism, which is found in the human body, in which the biological organism assists in recovery of the damage, which is caused to the skin. The material, which has been developed to inhibit the characteristics of self-repair, is polyurethane polymer, which has this remarkable property to repair itself when it is exposed to the ultra violet light. Polyurethane polymer- self-repair material This is a naturally occurring material, which is found in the shells of the crabs.

Invisibility Technologies

Invisibility is often used in movies to express a magical feeling in the minds of the viewers. The word ‘invisible’ itself is magical and needs a lot of connotation. When something is invisible, it creates a magical effect and a questioning mind and this makes the viewers probe into the field of invisibility technology. Really is there something called invisibility cloaking? Fictional movies have used invisibility cloaking to make something disappear for some time and when the cloak is removed, the thing or the person appears again. In 2008, a physicist named Michio Kaku prophesied that a feasible invisibility device like the ones used in Star Trek can emerge from research laboratories. He also quoted David Smith of the Duke University who had used meta-material to bend light around an object and also he quoted that German scientists have found that a meta-material can make the red light go around the object. This has become true, and due to the advanced technologies and the developments in the scientific research, a real world cloaking device has been created which has the capacity to obscure things to no less than one wavelength of electro-magnetic emissions.

The Advance Snow Lab Can Predict More Accurate Avalanches

If you’re being offered to do some researches, by studying the nature of avalanches, would you mind to risk your life on it? Well, you might say, “Why should I do it?” Do you know, Ed Adams, a 58 years old civil engineering professor has traded in his dynamite for a more challenging approach! He has used a $2 million new snow lab, where it’s aimed at gaining a better understanding of how avalanches occur. The National Science Foundation and the Murdock Charitable Trust funded the snow lab, where it has been named as “Subzero Research Facility”. According to Adams, this lab will help the experts getting to know the avalanches and more importantly, the best and more accurate ways to predict them. Avalanches are difficult to understand and hard to predict comparing to earthquakes, as they can be suddenly happened without even an early warning on it. According to the New York Times, there are totally 31 winter ski resorts should be pay attention with, 16 in the United States and 15 in Canada. The new snow lab will allow Adams and his colleagues to set the artificial sun at varying conditions to form different structures of snow crystals.…

You Can Be Totally Invisible With This Invisibility Cloak!

If you a big fan of Harry Potter series, then you must be very familiar with his invisibility cloak, where he uses it to hide himself from being spotted by anyone else (Although Alastor Moody can easily penetrate it by using the magical charmed eye!) You might think that It is impossible to develop the invisibility cloak, as this stuff only exist in the magical world! Guess what, the scientists from Duke University explained how to hide objects from a dramatically extended range of wave lengths, and they informed that the invisibility cloaks for visible light could be done within the next six months! David Smith, the professor of Duke University said that the invisibility cloak will be accomplished within six months of time. This invisibility cloak has its own name, The Duke Cloak! According to the scientists from Duke University, if you want to manipulate light, the microscopic surface of a material must be smaller than the wave lengths of light that being used. If not, the invisibility cloak won’t work as it did. However, there’s still a limitation for this invisibility cloak, where it only works in two dimensions. The scientists have mentioned that they will gain up…
