NEW Li-ion BATTERY DESIGN BOOSTS ENERGY CAPACITY AND CHARGE RATE 10-FOLD

For years, battery designers have been looking for the next big thing in energy storage technology that could replace the lithium-ion batteries currently found in everything from laptops to smartphones to cars. It turns out they may have simply needed to rethink the existing li-ion battery. Northwestern University researchers have re-engineered a lithium-ion battery that can hold ten times the charge of current batteries on the market, and can charge ten times faster.

The trick: a redesigned anode that addresses the two main issues holding li-ion batteries back--charge capacity and charge rate. Li-ion batteries work via a chemical reaction in which lithium ions are swapped between two ends of a battery (known as the anode and the cathode). As energy is burned by a device, ions travel from where they are stored in the anode through an electrolyte to the cathode. In the process, electrical charge is passed to the device as the ions make the transition through the electrolyte. When the battery charges, the ions move in the opposite direction, from cathode to anode.

Current anode design is based on graphene sheets--one-atom-thick layers of carbon--that store the lithium ions. But these anodes can only store one lithium atom for every six carbon atoms, a rather low charge density. Designers have experimented with materials like silicon, which can hold four lithium atoms for every silicon atom, but silicon tends to expand and contract significantly during the charge process, causing it to fragment. This naturally reduces the lifetime of the anode. 

A graphene-based design also slows the charge rate. Because of the geometry of graphene sheets--very thin but very long--lithium ions have to make a long trip to the edges of the graphene sheets and then push their way inside. This causes a kind of ion bottleneck around the edges of the anode and slows the charge rate significantly.

The NU team sawed through these problems significantly by rethinking the anode and incorporating a hybrid graphene-silicon design that boosts capacity and charge rate at the same time. First, they sandwiched layers of silicon in between the graphene sheets, allowing greater numbers of lithium ions to come to rest there. The silicon still expands and contracts during charging and discharging, but the flexibility of the graphene still holds the anode together. The silicon can fragment but it still stays in place, allowing the anode to hold greater charge.

The team then used chemical oxidation to punch tiny holes in the graphene sheets--just 10 to 20 nanometers across--so the lithium ions can move through the graphene rather than having to go around to the edges of the anode (where the traffic jams were occurring). This shortcut allow lithium ions to pile into the anode quickly during the charge process, giving charge rates a 10-fold shot in the arm.

And that’s just the anode. The researchers next plan to rethink the cathode to further boost efficiency and effectiveness. The better li-ion battery could hit the marketplace in the next three to five years.

ECO-FRIENDLY BATTERY RUNS ON OLD NEWSPAPER

Paper-Powered Battery Sony

 

I'll start you guys off with a quote here: In talking about Sony's new battery technology, which uses old cellulose product like newspapers and cardboard to generate electricity, the BBC says: "Their work builds on a previous project in which they used fruit juice to power a Walkman music player." Thank you, crazy Sony recycling-engineers.

This new tech relies on turning cellulose products (including, lest we forget, the paper greeting cards all you Earth-hating monsters are exchanging this time of year) into glucose sugar. That's done by introducing the old paper products to a solution of water and cellulase, an enzyme found in nature, and, um, shaking it. The cellulase solution decomposes the cellulose to form that necessary glucose, which is in turn combined with oxygen and some other unnamed enzymes, producing electrons and hydrogen ions, the former of which is fed into batteries to charge them.

If you're wondering where in nature this wood-eating cellulase enzyme is found, look no further than the termite. Cellulase is naturally occurring in the wood-eating species, and in fact the Sony researchers involved in the project actually compared their technique to that of a termite.

As with all new battery tech, especially in the early stages like this one is, the battery isn't powerful enough to run high-demand gear. A portable music player, like the Walkman™, is about all it can handle at the moment. But as the byproducts are basically harmless (water and gluconolactone, a neutral product often used in anti-aging cosmetics), it's definitely a tech we'd like to see improve and become viable.

THE WORLDS' FIRST "NANO EAR"

The 'Nano-Ear' Courtesy: APS 

 

German researchers have turned an optical tweezer device into the world’s first “nano-ear” capable of detecting sounds six orders of magnitude below the threshold of human hearing. Using an optically trapped gold nanoparticle as their listening device, the team says they can now detect sounds made at the bacterial level or use their device to tune (or perhaps to test?) the minuscule MEMS machines of the future.

The nano-ear is pretty simple, considering that it relies on technology that has been laying around in the lab for decades now. Optical tweezers are laser devices that use light to trap or manipulate a small particle in a particular point in space by drawing the particle to the most intense point in the laser beam’s electric field. By trapping a gold nanoparticle in just such a optical trap and measuring the influence of various sound waves on that particle, the found that they can “listen” to very small vibrations.

That means sound analysis at extremely low levels. The gold nanoparticle itself is just 60 nanometers (that’s 60 billionths of a meter, or roughly a thousand times smaller than a human hair), which makes it pretty sensitive to very small forces. The researchers used both a “loud” source--a tungsten needle glued to a speaker that vibrates at roughly 300 Hz--and a second source made up of bunches of other gold nanoparticles heated by a second laser to vibrate at just 20 Hz. The nano-ear could hear them both loud and clear. The sound waves nudge the trapped gold nanoparticle in the same direction that the waves are propagating, allowing for precise measurement of the sound itself based on the particle’s motion. Experiments showed the nano-ear could detect vibrations down to about -60 decibels--or six orders of magnitude lower than human hears can. That means the device could be used to identify microorganisms or processes at the microscopic level by their sound signatures, or to help design and tune microelectrical mechanical system

GENERATING ELECTRICITY FROM SHOES'

Humans are not very efficient. When we walk, we waste close to 20 watts of energy per second. Instead of turning all calories into lift or forward motion, we turn most of them into heat that’s quickly dissipated. It is the way to harvest the wasted energy from human motion and convert it into about 10 watts of electricity.

The device is based on a physical phenomenon called electrowetting: If you apply electrical voltage to certain liquids, the liquid moves. This means you have converted electrical energy (the current) to mechanical energy (the liquid in motion). We reversed the process, forcing liquid to move over electrodes. In the shoe, you have two flexible plastic bladders, one under the heel and the other under the toe. The bladders are filled with a mixture of oil and water and connected by a thin, snaking tube. When you step down on your heel, you compress the rear bladder, and several milliliters of liquid travel through the tube to the front bladder. Step on the toe, and the process is reversed.

 

The tube is lined with a thin film of electrodes, and as the liquid slides back and forth, the electrodes charge—electrowetting in reverse. A small battery stores the energy, and you can access that energy by way of a micro-USB port on the heel of the shoe. The Inventer also invented a way, like Wi-Fi, to transfer power from shoe to cellphone battery. Military or police might like having a regular supply of power, but most people wouldn’t be happy dealing with wires connected to their footwear.

Games for football lovers on iPhone and Android

 

The big game is this weekend and most American's will tell you it's a lot more than just a football game.
Many people make an event out of the game with parties, barbeques, and betting pools, even if their favorite team isn't in the running. Even the commercials shown during the game are an event in themselves with advertisers spending huge amounts of money for 30 second and one minute spots.
While you wait for the Sunday's festivities to kick off, I've put together a collection of mobile games to get you excited for the main event. Most of the time I only write about iPhone apps in this space, but this special event calls for a special post.

Want 4.5GB of free Dropbox space? Be a guinea pig
