Thousands of Transmissions on a Single Charge
This new battery is one application of organic radical battery technology, which uses a type of plastic known as organic radical polymer, first proposed by NEC in 2000. An organic radical polymer assumes an electrolyte-permeated gel state, which makes the battery extremely pliant, and with electrodes developed using thin-film technology, the battery is a paper-thin 0.3 mm.

The organic radical polymer has a fast electrochemical reaction that enables electrolytic ions to move freely through the material and reduces charge times to less than 30 seconds. Since it does not use any of the heavy metals common in conventional rechargeable batteries - such as lead and cadmium - this rechargeable battery is also very environmentally friendly. When used with radio frequency IC tags (small radio transmitter tags attached to products and other objects for the purposes of identification and tracking), the battery provides enough power from one charge to send out tens of thousands of transmissions.

These batteries can also be installed directly onto IC cards to power wireless communications that enable the cards to regularly transmit information from remote locations. One possible application could be for commuter passes. A commuter could leave a battery-powered, IC-equipped commuter pass in a pocket or wallet and pass through turnstiles of a station without touching the card.

Wearable PCs
With the increasing miniaturization of computers in recent years, the number of mobile phones, personal digital assistants (PDAs), portable game systems, portable music systems, and other devices that people carry on a regular basis - in addition to laptop computers - is increasing. In the not-to-distant future, computers may be worn like clothing and accessories, becoming as ubiquitous as glasses and wristwatches. This type of computer has been dubbed the wearable PC.

As computers have become smaller and lighter, providing power to run these devices has become a major issue. An ultra-thin flexible battery can be molded to the fine contours of the human body, which is a major breakthrough for wearable computers. The day is not far off when it will be possible to receive information anytime, anywhere - even while one is strolling casually down the street, hands in pockets. This battery has applications in intelligent paper and other thin electronic devices as well, and is expected to spur development in this field.

In a statement, NEC declared its determination to continue its research to improve battery energy density, extend the length of time each charge lasts, shorten charging time, and provide higher quality, more reliable rechargeable batteries.

Just because you have a website online doesn’t mean people will come visit it. This means that business will not be the best when you don’t make sure your website is optimized for the internet. Even if you have tired a destiny designing the perfect website, unless you use the right off page SEO, it will have no important number of visitors. This article will tell you about the right way to go about popularizing your website.

Broadband Internet access has changed the ways in which most people use the Internet. In the days of dialup, most people were limited in what they could do online. Simply downloading a picture could take quite some time. However, broadband Internet has revolutionized the world. Today, thanks to high-speed connections, people are able to watch movies, stream music, play online games and more. However, 4G technology promises to kick things up even further. What is this technology? What does it offer you? What benefits can you gain here?

You will find that 4G technology refers to 4th generation cellular broadcasting. As such, it can be measured to be related to 3G and even 2G in a sense. However, the “G” in the name is really the only similarity here. 2G is speedily being phased out over most urban and suburban areas, and even 3G has been replaced in quite a few regions. 4G is beginning to become the standard in the industry, and for good reason. It offers you the ability to connect wirelessly to the Internet from anywhere that you have signal. This includes your home, your car, a hotel, a hammock on the beach – you name it. If you have 4G signal, then you can access the Internet.

There are numerous benefits to be found with this technology, as well. For example, you will discover that it enables you to cut out your home phone bill if you like. As more people switch to using their cell phones for communication, landline phones are generally only needed for Internet access. However, you will still have to pay a fee for that landline, on top of the costs for your Internet connection. Fourth generation wireless technology allows you to ditch your phone line if you want. You will be able to connect wirelessly at any point in your home. If your computer, PDA, cell phone or netbook does not have the capabilities for this, a simple USB modem can get your connection up and running.

Another massive benefit found with 4G broadband technology is the fact that you can carry your Internet connection with you when you travel. In the past, this meant having to tether your phone to your laptop for work or play. Alternatively, it meant paying additional fees or attempting to navigate a difficult connection process when staying at a hotel. Some hotels didn’t even offer Internet access. In these cases, you had to go in search of a wireless hotspot. Fourth generation wireless connectivity ensures that you do not have to worry about these problems.

4G technology offers numerous, obvious benefits for both leisure users and those who need to remain connected for work. In addition, you will find that this technology allows you to save money through quite a few different methods. If you are no longer forced to pay for a landline you don’t need, or pay for an Internet connection at a hotel when you travel, you will realize important savings.

A new technique that uses a laser to vaporize materials like rocks and steel to consider their chemical composition is finding new applications from Mars to forensics.

Thanks to its moderately small size and low cost, laser-induced breakdown spectroscopy is emerging from the laboratory and turning into a precise tool for figuring out what something is made of. What had been a technique largely for scientists now can be transformed into a tough, small system that can be operated by a technician instead of a PhD.

“The same things that make it amenable to go to Mars also make it amenable to go out in the field,” said Jose Almirall, a chemist at Florida International University who has a grant from the Department of Justice to explore how crime labs can use the technology.

NASA will be deploying a LIBS system called the “ChemCam” on its new Mars rover, now named interest and scheduled to launch next year.

LIBS works by blasting a material with a high-energy laser pulses. The Mars interest rover will send an average of three pulses a second, each one 5 nanoseconds long. The power during that pulse is in the range of 10 megawatts.

That’s not enough to shoot a hole in your hand, but it’ll leave a mark.

“I’ve shot myself and you might see a little spot where you shot yourself, if it’s just one laser shot,” said Roger Wiens, a space scientist at Los Alamos National Laboratory, who developed the ChemCam for the Mars Curiosity mission.

In some cases, the ChemCam will be focused on rocks for more than 15 seconds. If you were to do that to your arm, “You’d be in pain,” Wiens said.

There are no plans to use the laser for anything but science, but there’s something science-fictionally satisfying about the next Mars rover coming prepared with a laser “gun.”

The laser shots vaporize a crater less than a millimeter across, turning its molecules into a 14,000-degree plasma. The atoms are shorn of their electrons, but as the plasma ball cools down, they return to a more normal state. The electrons drop into their orbits around the nucleus and as they do so, the little plasma ball emits light.

“You can see it with your eyes and it makes a little zapping sound when you do it,” said Wiens.

The specific color of the light tells scientists exactly what element they are looking at if they pass it through a spectrometer, which can precisely measure the wavelength of light.

Lasers have been used to create small clouds of atoms for spectral analysis in the past, but those systems require a separate torch that heats the atoms into a plasma. With LIBS, the same laser blast does both jobs. It’s this simplicity that could aid the technology’s spread. A 2006 Cambridge University Press book on LIBS declared the technique “perhaps the most versatile method yet developed for elemental analysis.”

On Earth, there are plenty of times when one might want to know the very precise composition of a substance. In late 2009, for the first time, a LIBS analysis was used in a court. It helped identify a would-be bank robber by the glass on his clothing in Maryland. After being locked in a vestibule by secret alarms, he shot his way out and sped away. After being detained, some pieces of glass were found on his clothes. When Almirall’s team compared the precise composition of that glass with the stuff from the bank, they came back with a probable match.

Glass made in different places and at different times is quite distinctive at the molecular level, Almirall said. In modern manufacturing processes, sodium carbonate and calcium oxide are usually added to the base silica. But tiny amounts of other elements such as strontium can act as a particular type of glass’ signature. The older a glass-manufacturing plant is, for example, the more zirconium leaches into the glass melt.

“The glass manufacturers don’t care if they have 10 or 20 or 30 parts per million of strontium,” said Almirall. “We’ll look at seven, eight, nine different elements in the raw material to detect differences.”

The level of accuracy that LIBS can offer may eventually help manufacturers do quality control on their products. Almirall is even thinking about how to use a briefcase LIBS system to test products for U.S. Customs to ensure their safety and provenance.

“If you were receiving some toys and want to immediately know if you have lead in these toys, LIBS could do that very quickly,” Almirall said. “Green light, no lead. Red light, there is lead.”

Several companies are trying to commercialize LIBS systems including Applied Spectra of Fremont, California, and Stellar Net of Tampa, Florida. Stellar Net’s PortaLibs is shown above. Clearly, the technology has gone a long way toward fulfilling the promise Wiens first saw in it 13 years ago.

“I was looking for other technologies to put into space and a colleague here [at Los Alamos Lab] took me to his laboratory and showed me a little laser the size of a cigar and a rock across the room and a little transistor battery,” Wiens recalled. “He had the laser hooked up to the 9-volt battery, charged up some capacitors for a few seconds, and then zap, across the room, there was a spark.”
