Printable Explosives Detector: Ammonia Plays Vital Role>>>>>>>>

 Here is a good news from Georgia Tech Research Institute (GTRI) where Dr. Krishna Naishadham and Judy Song (XiaoJuan), they have invented the first ink-jet printable ammonia sensor for affordable, practical explosives detection. This device which employs carbon nanotubes and is printed on paper or paper-like material, including the plastic base polyethylene terephthalate material using standard inkjet technology that was developed by scientists at the Georgia Institute of Technology.

It’s ink consists of silver nanoparticles that held in liquid emulsion that will get passed through an ink-jet printer’s 212 F (100 degree Celsius) temperature. And they say that this special ink with carbon nanotubes itself is treated with ultrasonic waves going through a process known as sonification which alters the viscosity and thus producing more homogenous ink for greater effectiveness.

These about 1/50,000^th width of human hair’s carbon nanotubes are then coated with a conductive polymer capable to attract ammonia for more effective explosives sensor in detecting trace amounts of ammonia as low as five parts per million. It uses different type of coatings so carbon nanotubes will be able to detect other chemical including gases. In this Ammonia is a key ingredient in the manufacture of many explosives.

The principal researcher Krishna Naishadham revealed that, “it incorporates a sensor and a communications device in a small, low-cost package that could operate almost anywhere.” Right now, the sensors made by using this method require some power in order to operate but scientists are already working on developing a sensor that runs passively without any power consumption at all.

The device is using both a sensor and a lightweight antenna, would allow what’s known as standoff detection, signaling the presence of trace explosive materials at a distance without endangering human lives. The printable explosives detector could deliver vitally needed, life-saving detectors that can be mass produced cheaply in any corner of the world.

E-Volo: First Manned Flight of an Electric Multicopter!!!

Do you ever heard about theElectric multicopter? Thomas Senkel has found the multicopter, he is a physicist and designer as well as the builder of the ‘multicopter’. To say about the multicopter, is a first one seat ‘multicopter’ prototype and it took off from the ground back in late October last month.

The first pilot to test that, was by Thomas Senkel e-volo, on an airstrip in the southwest of Germany, flew up on the air about one minute and 30 seconds. And piloted the aircraft from a center-mounted seat, using a handheld wireless control unit.

 It is a 16 blade multicopter which has successfully lifted a human for more than a minute. It uses multiple mini helicopters arranged in a square in sets of four configured to achieve lift. They say that the multicopter is simpler in construction and mechanics compare to a helicopter and safer and the multicopter could still land safely even with up to four of its motors failed or when the propellers experience some minor wear.

Multicopter has onboard computers that is designed with custom firmware that control and monitor the rotational speed of the propellers, dictating the attitude as well as the altitude and direction of the aircraft. The solo pilot could maneuver the multicopter within a fairly small area, no need for long and wide runway for conventional airplanes or helicopters.

 This multicopter is built with four propellers and it can be said that is similar to Parrot’s A. R. Drone Quadricopter, only this time, it lets a man to sit on top of the multicopter and fly it around. It will be ready within the next few years to come with the commercial version of the e-volo’s multicopter and it is also said that, it’s going to come with the option of gas/electric hybrid model for increase flight time to about an hour.

 

On Saturday 29^th Oct 2011, Thomas Senkel tested the flight that lasted one minute and 30 seconds; its characteristics are good natured. And it is also said that without any steering input it would just hover there on the spot. The pricing and the availability is still mystery but I think it’s going to be bit cheaper than a helicopter, anyhow this will also make us still expensive, you feel the same I think.

Fashionable Cufflinks- Polished Silver Wi-Fi Hotspot and USB Flash Drive!!!

When You look at the picture above you think this is a flash drive but it's not just a flash drive, it's a Wi-Fi Hotspot and USB flash drive cufflinks. Ravi Ratan, who the Luxury cufflink maker has introduced new type of cufflink with an geekier pair of fasteners, it doesn’t only link the cuffs it is a pair of 2GB flash drives that they can also act as Wi-Fi hotspots.

Only when we plug either of them to a computer that’s connected to the Internet before it can create a network. And it can be done for free with the software like Connectify which is already known. Instead of Wi-Fi, it would be awesome if they worked like the Mi-Fi and could turn a person into a walking wireless network.

It is a pair of Lighter Cufflinks and it is pretty sure, the sweetest pair of sleeve clasps which we’d ever seen. This is a Wi-Fi and 2GB Polished Silver Oval Cufflinks that keeps our documents just inches from our fingertips at all times. In addition, it offers a Wi-Fi hotspot when we plug them into our computer.

 It features,

·         Approximately 7/8” x ¾” inches

·         2GB storage capacity and Wi-Fi Hotspot Cufflink

·         Engravable whale backing

·         Rhodium plated base metal with silver finish

They are practical and fashionable cufflinks, the polished silver Wi-Fi hotspot and USB flash drive cufflinks and this is really suitable for us. Each cufflink features smooth oval appearance and rhodium plated base metal with silver finish in order to fasten the sides of the cuff on our dress in a fashionable way.

 The most important thing is each cufflink features unique function, one cufflink comes with a 2GB USB flash drive for our various documents while another has a built-in Wi-Fi hotspot. Just we’ve to do is downloading accompanying software and plugging the cufflink into our computer and we will get a wireless Internet connection for our smartphone, tablets and other wireless devices.

This polished silver Wi-Fi hotspot and USB flash drive cufflinks are priced at $250 USD. If you’re interested with this cufflinks, just go to this Cufflinks.com official site for more details

Solar USB Charger: Captures Maximum Amount of Sunlight!!!

Nowadays, teenagers use many gadgets like iPhones, Blackberries, iPads, Droids, iPods and so on and these devices are common with its battery, need to charge it when the battery is low. And we’ve to carry on our charger all time and search for the power to charge the devices. Now the new technology has been introduced by Quirky to charge our devices anywhere.

 Quirky revealed the Ray Solar Charger and it is also said the best solar charger we’ve ever seen. This has a compact battery with enough juice to charge a cell phone and it has a built in suction cup to attach the flat surface like to the window of the car or airplane that has built in Kickstand which conveniently holds our device’s USB cable.

 This Quirky Ray Solar Charger charges all our various portable gadgets on the go that can be quite the challenge. This solar powered charger looks to be pretty useful. This Ray Solar Charger isn’t the first solar charger on the market but it doesn’t mean the less it has the advantage of suction cup that can stick window and the suction cup is made up of the silicone.

But the only disadvantages is when sun is smiling in the sky we’ll smile, talk and enjoy but when sun doesn’t smile, the same thing to us. To charge our mobile devices, all we need is some sun. Power comes out through the USB port and the internal battery can store enough energy for a full phone charge.

 The original idea for Ray came by way of Mifflinburg, Pennsylvania’s Brandon Craven. It was then tweaked by 988 “influencers” on Quirky. They’ve developed suction cup that can be used on any glass surface such as house windows, or windows in cars and planes. In-car use while driving is a dubious idea anyhow they’ve given the prevalence of lighter-based car chargers.

 It has tilting kickstand that allows users to place the charger on flat surfaces and also serves as a place to store the USB cord. The Ray measures 2.5” x 2.5” x 3” and Quirky notes that it is subject to change during production. Quirky community had admitted that it is now available for pre-order and is priced at US $39.99. The production will not start until and unless 2,000 orders are placed.
