3D Printing Technologies

Posted on June 17, 2010 | 2 Comments

3D printing is used to come up with three dimensional objects and is a form of additive manufacturing. It is now easier and more affordable to come up with a prototype using the 3D technology. Before these technologies were introduced, it used to take several hours, skilled labor and tools to create a prototype.

One form of 3D printing technology is made up of inkjet printing systems. Fine powder layers made of resins, corn starch or plaster is bonded selectively on adhesives produced by the inkjet print heads. This kind of technology makes it possible to print a full color prototype and is considered to be one of the fastest methods. Continue reading →

Posted on May 25, 2010 | Leave a comment

The lab is a diverse area. There are many instruments set up in a laboratory. There is a lot of variation in the type of these instruments and technologies in a lab that we can see today. If we go thirty years back in time then we will come to see that the technologies that exist in the labs today are far much better than those that existed previously. It can hence be seen that with the lapse of time a lot of advancements are made in the science field which has lead to the improvement in the technologies that are used in the labs. A lab basically needs the best of instruments so that all the purposes and experiments that need to be carried out are done very efficiently and very easily. The types of instruments that are available in the labs today are the most developed and latest ones. It was not even imaginable to the people few years back that such instruments could also exist. But the answer is here as we can see that yes we have achieved the best ones in the recent years. The ones that we have today are much more easy to use and are far too much sophisticated than the ones that were used long time back.

Motion Powered Nano Devices

Posted on May 14, 2010 | 2 Comments

Nano devices have become very popular and famous these days. All this is due to the advancements being made in the field of science and technology. Nano devices are being made that are being powered by motion also. This is the latest advancement that has been seen lately. It has also made its use in the field of electricity. It has been seen that when 20 thousand nanowires were made to be crammed up so as to make a three centimeter square the very first power device can be created which will be powered on its own by the help of the piezoelectric materials and items. This was first done by the company known by the name of Georgia Tech. This material which is said to be piezoelectric has its own functionality. When it is pushed or pulled there is some sort of mild electric form charge generated. Hence we can see how it works. With more advancements it can also be seen that these piezoelectric nano wires can also be woven properly in form of any simple cotton shirt  or in any person’s shoe which would charge the battery of a cell phone by just simply walking. This is the most important and attractive feature of this which is also responsible for the popularity it has gained.

Molecular Transistors will make breakthrough in electronics

Posted on January 25, 2010 | Leave a comment

Nobody can doubt the effort of scientists when it comes to transistors and their importance in modern technological advancements. Over time, transistors have been in the market, designed from singular molecules. Electron flow in these transistors has been facilitated by the modulation of energy produced by molecular orbits or orbital. This behavior has greatly influenced the genesis of current and future molecular transistors and other devices. Since transistors (integration of circuit elements) work with the electric current flowing within the electrodes (drain and source electrodes), trying to improve voltage put to the 3rd electrode, normally referred to as gate electrode, the manufacture of these transistors takes time, money and energy.

Determination by scientists and researchers so far has bore fruit; they have made a breakthrough with the first molecular transistors being made. This brand of transistor is made from one molecule, has its benzene molecule bonded to the vibrant gold contacts and works or performs like the silicon transistors. The presence of varying energy degrees in the molecule can easily be manipulated by varying states of energy. Through this you can be able to assert yourself in controlling the passage of current via it. Continue reading →

Augmented reality in industry

Posted on January 22, 2010 | Leave a comment

Augmented reality also referred to as the AR is a concept that is used to view the corporal world either directly or indirectly. When viewing the world this way, the essentials are practically computer created imaginary things thus creating diverse certainty. The augmentation of the world is viewed in the actual time and in semantic situation with ecological basics like soccer scores on television in mind. AR (Augmented reality) works hand in hand with technology to make the physical world networked and technologically working. Among the augmented realities that are incorporated with technology includes computer image and entity identification. Any non-natural detail about the surrounding and the images are capable of being stored and thereafter recovered as information concerning the real world.

Augmented reality has continued to get impetus as the years and technology advances. The most recent use of the augmented reality was used in the testing of the United States Marine Corps on a resistant steeple. The system that was used was called ARMAR (Augmented Reality for Maintenance and Repair) was designed and made at the Columbia University’s Graphics and user Interface laboratory. A mobile phone was used to view and manage the graphics in conjunction with a head built display that assists its users in repairing it. The augmented reality in industry was designed to use 3D motion picture that assisted in the exhibition of the appropriate gadgets and methods in a variety of repairs. Up to date, this system is still being used by the military personnel and has proven to be very beneficial. Continue reading →

Nuclear Reactor Types – Are they really safe?

Posted on January 7, 2010 | 1 Comment

The nuclear power industry along with the reactor technology has been constantly developing for more than five decades now. Nuclear reactors can be classified based on their nuclear reaction, the moderator material used, generation of the reactor, fuel phase, fuel type, coolant used, etc. The fission nuclear reactors are mostly dealt with because the fusion reactors are still in the developing stages and the fission reactors are already being used for the past six decades.

  • Based on nuclear reaction

This type refers to the thermal (slow) reactors and the fast reactors based on the speed of neutrons. Thermal reactors are the most affordable and common as they use the natural and raw uranium; and the neutrons are decelerated from their natural speed when emitted from the broken atomic nuclei, and uses a moderating material in the process. The Fast reactors are very expensive that require more enriched fuel. Continue reading →

Full Body Scanners – How do they work?

Posted on January 5, 2010 | 6 Comments

The new full body security scanners might become a popular alternative to body searches with the increased alleged terror threats over the globe. The full body scanning system has taken the world with a surprise in the past recent months. It is the most advanced system of the whole-body imaging technology that involves scanning of the whole body through clothing revealing both metallic and non-metallic hidden objects, including weapons or plastic explosives.

The U.S. Transportation Security Agency (TSA) had already tried this concept of whole-body imaging at six airports in mid 2009 to look for threats that normal metal detectors could not find. The process to install these scanners at more airports in several of the U.S. cities is already heading rapidly, with the recent alleged unsuccessful terrorist attempt on a Christmas Day flight to Detroit. To combat this threatening problem and for the security of the people, the TSA has worked with two basic technologies to upgrade its passenger screening systems- the Millimeter-wave and the Backscatter X-ray.
