Multiferroics: The Unique Combination of Electric and Magnetic!

The advent in technology field has been created many miracles, which it seems hard to be achieved in the past. By the way, have you ever heard about this stuff, “Multiferroics” before? No matter you’re hearing it for the very first time, or you’ve been involved with it, you got nothing to lose to know it better here, isn’t it? For your information, multiferroics are the unique combinations of electric and magnetic properties, where can constantly coexist. They are potential cornerstones in future magnetic data storage and spintronic devices. It provides a simple yet faster way to turn their electric and magnetic properties on and off simultaneously. Ramamoorthy Ramesh, one of the renowned professors in the Department of Materials Science and Engineering and the Department of Physics at UC Berkeley have successfully demonstrated that by just using a simple electric fields, we are able to create, erase or even invert p-n junctions in a calcium-doped bismuth ferrite film! He claimed that the next generation of computers is going to be smaller, faster and more versatile than today’s devices. It can be easily achieved, especially if the manufacturers applying the multiferroics method into the computer field! [sciencedaily]

New Broadband Cloaking Technology

Vladimir Shalaev, Robert Burnett and Anne Burnett are the amazing trio from Purdue University who created a new type of invisibility cloak. It claimed much simpler than previous design and works for all colors of the visible spectrum, which making it possible to cloak larger objects than before. According to Shalaev, the new broadband design is a simpler device that based on a “tapered optical waveguide”. By the way, waveguide is representing established technology, including fiber optics that being used in communications and other commercial applications. Since the new technology enabled the researchers increase the cloaked are of broadband, thus it offers a brighter hope of cloaking larger objects in the near future! Shalaev and the research group promised that there would be a more advent broadband cloaking technology before the end of this year. So, let’s crossed our fingers and wait for the good news.

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.
