Seaweed could give lithium-ion batteries a green power boost ...

Seaweed isn't just good for wrapping delectable pieces of rice-padded fish; it’s also the missing ingredient researchers at the Georgia Institute of Technology and Clemson University have been looking for in order to make lithium-ion batteries more efficient. According to a paper published in the latest issue of Science, the rechargeable lithium-ion batteries found in many of today’s gadgets, may be improved thanks to the living cells from alginate, a material that’s extracted from the common and quick-growing brown algae. Currently, lithium-ion batteries include a non-active binder that's crucial to the battery's stability. The polymer binder is mixed with an electroactive <a href="http://www.ghdstraightenerscheapest.com/ghd-2010-new-blue-serenity-p-5726.html"><strong>ghd for hair</strong></a> graphite powder and the mixture is then spread on the metal foil that collects an electrical current when dried. The researchers found that if silicon particles are used as the base of the electroactive powder instead of graphite, the battery can hold more ions. However, the silicon-based binder seems to crack as the particles swell up to 4x their original size while the battery is charged. The researchers found that the solution to this problem is to use the algae-based binder that won't crack as the anode swells like the silicon version. This allows a silicon anode to be used with the alginate binder. Since seawater has such a high concentration of ions, researchers thought it might be the perfect natural binder. After some tests, they found that the alginate from the <a href="http://www.ghdstraighteners2011-cheap.com/ghd-iv-gold-styler-p-5725.html"><strong>cheapest ghd straighteners uk</strong></a> brown algae did in fact prove to be an effective binder for the silicon anode. The alginate can be extracted by boiling the kelp in soda water. Â*This left the researchers <a href="http://www.ghdstraighteners2011-cheap.com/2010-new-ghd-butterfly-pink-p-5740.html"><strong>ghdÂ*purpleÂ*Â*</strong></a> with a battery that's overall less expensive, can store more energy, and can last longer without having to use any of the toxic chemicals currently used in the battery’s manufacture. Alginate can be dissolved in water, which means you can manufacture it in a cleaner way than the current process. Gleb Yushin, an assistant professor in Georgia Tech’s School of Materials Science and Engineering, said making less expensive batteries that can store more energy and last longer, thanks to the alginate, could “provide a large and long-lasting impact on the community.” Of course, all this might be academic if the new, safe jelly-like polymer gel batteries turn out to be a suitable replacement for rigid lithium-ion units. via MIT Technology Review and Georgia Tech

Harvard Instructor comments: If companies get the help of financial capital, their ability to operate be doubled.
------------
know this method more than men, Viagra in short supply, and gradually to 2, 3 pigs for a Viagra.
Harvard Instructor Comments: This is inflation.
------------
when the price rose to 16 a pig,la gear originals, when Harvard Instructor comments: The man has entered the marginal cost, in addition to have confidence in their own ability and future beyond good intentions, the actual current flow is zero pigs.
but more and more for men and pigs, the decision to sell Viagra, expanding production capacity, introduce a sub-Viagra, if you lack a pig, as long as you promised to the woman one night room, can be borrowed, something submit them into the pig model, this method greatly facilitated Viagra sales.
Harvard Instructor Comments: This is the loan, so that enterprises can borrow based on future revenue options liquidity

Viagra stores later in a pig even if you have No, as long as you promise to the girls room for one night, can be borrowed, things are after the money pay pig.
Harvard Instructor Comments: This is financial innovation, so that people now spend future money, you're old anyway, so the money you spend the next fixed.

their bonds in order to prevent future losses, the company decided to give it to buy the insurance, bond sales so much easier, because once the bond problem You can also get the insurance company of the debts, wow, great erupted in bond sales, the insurance company was also a great income insurance for nothing.

male pig for too many long lines waiting, the woman can not afford, said his aging mother quit, I move, there are many a time with Viagra due to male pigs.
Harvard Instructor Comments: This is an individual phenomenon, belonging to normal market fluctuations will not affect the entire economy.
------------
result has been reluctant to move back to the woman. Part of the male pigs due to no income, but to repudiate the results for a large number of bonds is not due to eat pork, the bond company to look, a Viagra 16 pigs, which have played where, declared bankruptcy
Harvard Instructor Comments : This is the sub-prime crisis will not affect the entire financial industry.

where the company also knew the bond on the bond insurance, insurance companies, a look, where it can afford to lose, so also announced it would close down.
