New high-power battery - leading to big hybrid vehicles by Blacklisted 4u & mohanraaj

| New Boom for smart phone technology,etc... |
A new type of high-power battery may help make larger hybrid vehicles a reality, according to a research paper published this week. A group of scientists at MIT have found a way to use carbon nanotubes to create a device that combines the strengths of batteries and capacitors, resulting in a battery than can both store a large amount of energy and put out a high rate of power. The ability to provide a better combination of high power and rapid discharge may help engineers tailor the batteries to a broader range of vehicles.
Batteries and capacitors have long occupied independent niches when it comes to storing electricity. Lithium batteries can store a significant amount of energy using chemical processes, but can only supply a low rate of power; capacitors can deliver a lot of power at once by eliminating the difference between two oppositely charged plates, but have low total energy storage.
Researchers have been trying to mitigate the shortcomings of both devices for some time, by either forcing higher rates of output from batteries or more storage from capacitors. They've achieved some success in increasing the rate of discharge from lithium batteries by shortening the distance that the ions diffuse to a few nanometers, but the output remained too low for many high-power applications. Similar efforts to adapt capacitors have yielded limited successes.
To get the functionality they were looking for, researchers needed a material that could quickly shuffle ions around the battery, but would also bond strongly to them, ensuring a higher release of energy when the ions are released. As is often the case in materials science, they needed to look no further than carbon nanotubes.
To construct an electrode for their new battery, the researchers created alternating layers of carbon nanotube sheets coated with carboxylic acid and amine functional groups—these can undergo charge transfer reactions with lithium ion charge carriers. Their addition also seems to roughen up the surface of the nanotubes, increasing the surface area available for reactions.
The researchers tested a battery that used the layered carbon nanotube electrode on the positive end, and a lithium electrode on the negative end. The power output of the batteries declined as the nanotube electrode's thickness increased, placing a ceiling on its numbers. But an electrode three micrometers thick could still deliver energies of 200 watt-hours per kilogram (a bit better than current-generation lithium batteries), and a power of 100 kilowatts per kilogram. They were able to match the energy of lithium ion batteries at lower power outputs, and at high power had better energy delivery than the nanoscale-diffusion lithium batteries.
While these numbers were impressive, batteries with pure lithium electrodes are not the norm. For a more realistic setup, researchers tried instead using a composite electrode made of lithium titanium oxide along with the carbon nanotube electrode. They found that these batteries had lower energy and power, but at 30 watt-hours per kilogram and 5 kilowatts per kilogram, their performance is several times better than the current generation of capacitors. The battery was also very resilient, showing no drop in performance even after 2,500 cycles.
The new battery doesn't best either capacitors or batteries at their respective strengths— it stores energy only about as well as any lithium ion battery, and supplies rushes of power as well as a capacitor. However, it may find use as a versatile middle-of-the-road device that has high storage and can supply bursts of power if needed.
Researchers hope that this new style of battery will eventually allow for larger hybrid vehicles that are less reliant on their gas engines to sustain a high power draw. Potential benefactors of the technology might include tractor trailers and buses.
The authors indicate that they plan to continue by verifying how the electrodes behave on larger scales, where "larger" means tens and hundred of micrometers. They also hope to develop ways to prevent some of the energy loss during charging and discharging. The new battery may also benefit from a new method of assembling multiwalled carbon nanotubes by spraying them on layer by layer, which may allow fine tuning of the voltage differences needed during charge and discharge.

New anti-rape female condom, Rape-axe, debuts at South Africa's World Cup

South African inventor Sonette Ehlers explains how her new anti-rape female condom works, at her house in Klaemond in South Africa. She is distributing 30,000 of the device at the World Cup. 
antirape.co.za
Rape-aXe is a device which latches itself to the skin of the attacker, causing immense discomfort, allowing the victim to escape. Dr. Sonnet Ehlers has invented Rape-axe, a female device with jagged hooks that latch onto a man's penis during penetration.
The doctor is distributing 30,000 of these condoms in South Africa during this year's World Cup.
"It hurts," Ehlers told CNN. "He cannot pee and walk when it's on. If he tries to remove it, it will clasp even tighter."
South Africa has one of the highest rape rates in the world, according to Human Rights Watch. It is also believed that 16 percent of the population is living with HIV.
Rape-axe is inserted like a tampon and when embedded to a man the device can only be removed by a doctor.
Some have accused Ehler of creating nothing more than a new-age chastity belt.
"It not only presents the victim with a false sense of security, but psychological trauma," said Victoria Kajja, from the Centers for Disease Control and Prevention in Uganda.
But Ehlers said that she had taken the proper research and development steps before launching the product.
"I consulted engineers, gynecologists and psychologists to help in the design and make sure it was safe," she said.
Ehlers also pointed out how women take extreme measures such as placing razor blades in their nether regions to prevent rape in South Africa.
"I believe something's got to be done," she said. "This will make some men rethink before they assault a woman."
Toy Story 3 Romps in $109M Debut Keeps Pixar's record of opening at No. 1 perfect
Movie fans have not outgrown the Toy Story 3 gang. The animated sequel leaped to the No. 1 spot with a $109 million opening weekend, according to studio estimates today, becoming the third animated film to top $100 million in the first weekend. The others were Shrek the Third with $121.6 million, and Shrek 2, with $108 million.
It was by far the best debut for a film from Disney's Pixar Animation, topping The Incredibles' $70.5 million, and maintaining Pixar's perfect record of all 11 of its films debuting in the No. 1 spot. Toy Story 3 took over the top slot from The Karate Kid, which pulled in $29 million to raise its 10-day total to $106.3 million. The weekend's other new wide release, Jonah Hex, bombed with just $5.1 million.

WHY WOMEN REJECT MEN...... ?
Most men have never learned to develop their "inner self confidence"... and become the kind of guy that is literally BULLET-PROOF.
Most men HATE the idea of "rejection".
The idea of walking up to a woman and having her REJECT you causes most men to instantly feel sick and literally feel a horrible combination of nervousness and
confusion.
The heart rate shoots up, breathing quickens, eyes dart back and forth, thoughts of rejection fill the mind, and eventually the pressure becomes too much to bare.
The temptation is great to just "walk away"
because of the intense nervousness, triggered by the moment one decides to ACT, it goes away when you decide to "forget about it and walk away".
Most of the time (and I'm talking about probably 99% of the time here) men just walk away. They give up before they've even started.
If I just think about it, I can remember MANY times in my past where I wanted to talk to a woman, but I just didn't do it.
In fact, many of them are so vivid that I can remember the exact setting, what the girl looked like, who else was there, etc... And I'm talking about situations that happened YEARS ago.
I've found that for me PERSONALLY, my FEAR of rejection is actually FAR, FAR more painful and difficult to deal with than ACTUAL rejection in the real world.
The main reason for this is that most of the time when a man starts talking to a woman, she is actually rather nice about the whole affair.
If a woman isn't interested, she usually just says "I have a boyfriend" or "No thank you"... or she'll just walk away without saying anything at all.
"How do you deal with rejection?”
The answer: Don't worry about it.
Really.
No big deal and it does n't happen that often.
You'll find yourself telling your friends about it, and laughing together. Rejection from a woman is about as painful as getting a "0" on a test.
It's just insignificant.
SO, WHY WOMEN REJECT MEN...
Here are the main ones:
1. the guy isn't paying attention, and he does
something stupid to begin with.
Some guys think it's appropriate to walk up to a woman, put their arm around her, and say, "Hey baby, you sure do look hot tonight".
2. The guy doesn't stop when he should.
If two women are sitting alone at a table in the corner, and one of them is obviously upset, and you walk over to them and say, "Hi, can I buy you a drink?"... and the upset one looks at you and says, "No thanks, we're in the middle of a conversation" (then looks away from you back at her friend)... and you say, "Aw, cummon, have a
drink. You need to lighten up and have some fun"... and she looks back at you and says firmly, "We're busy"... and you say, "What, are you in a bad mood or something? I'm just trying to buy you a drink"... and she says, "We don't want a drink"... and you say, "Well maybe your friend does"... and the friend says, "No, I don't want one either"...
If you ever do something like this, you are a dumb ass, and you deserve to be slapped and have 47 drinks thrown in your lap.
3. Making a woman nervous with your body
language.
4. Not understanding a woman's body language and
other communication.
When you start talking to a woman, she will let you know within a very short time if she's receptive to talking to you.
If you've been reading too many books that say "A woman will signal her availability and interest by flipping her hair, licking her lips, and cocking her head coyly at you", then get over it.
This stuff happens to Brad Pitt, not to YOU.

ARE WE LEFT ALONE???
To tell you…
I really busted hard to get to something that might really interest my readers…!
Ooph…. Like my previous, which made many babes run in to crazy … May be this time… it’s not that freaky...! Its something that everybody has to think of…may be at-least when you while through this…!
I always dreamed of these celestial bodies. What makes these entities appear like they way you see them? What makes it truly complicated that u find answer to some questions which itself makes you fall in to another like the waves in the sea? Where are we now? Where do we go? And indeed are we alone? May be this blog is to try finding the answer for the last question “ARE WE ALONE…?”
If big bang theory can be relied, we are quite sure that universe is expanding. There exists some extra terrestrial (E.T) creatures living somewhere in this universe. We can never take the right to say this place is ours. We lived here for long.
They (E.T) may or may not be evolved the same way as we did (all species in this earth). They may have a different past. But it is possible to say that there is every possibility for the existence of life other than ours. The planet we are searching is very well formed earlier than ours (If big bang is right). The E.T we one day find would not be an organism of minute form. May or may not be advanced, but you never be passive in accepting it as a minute organism (condition-if and only if the planet is formed earlier than us). The reason we still search for their very existence is the fact that they are very far from us.
My perspective tends that the alien (E.T.) we search don’t need water or some other compound that we require. They may be of different form, different origin. Now I should take-up my word of calling them “LIFE”. They should be called as something else. Since life is something, which involves respiration, metabolic activities etc., we cannot expect them to do the same things that we do.
Darwin’s “THEORY OF NATURAL SELECTION” states in the heading “survival of the fittest” that an organism which accustoms themselves to the surrounding can only survive in the world. Hence an organism that formed in the other world might be accustomed to that condition (condition of that planet). The organism that exist there will be unfit to live here. They may be of different species that live in different conditions and quite a different world. They may have evolved in accordance to there conditions and scenarios.
I believe there might be some other evolutionary process by which a cell can be formed. Urey and Miller proved in the laboratory by bringing up the past conditions thus forming a single cell in there own lab. But we should check out the possibility that “is there a process other than that by which a cell can be formed”. If it is found, I think we can make history. We can revolutionize all theories that exist at present. We can thus prove that there is something beyond our reach. We should find a theory that explains all extremities of this universe. Did there exist anything before “BIG BANG’’. Is there an end to this universe? If so what’s next to it?
If we think this universe as a small room, our technology has reached only a small area. There is vast to be expedited. With this we are incapable of reaching to our nearest space neighbour. Will we able to invent the tech to do so? If so when? This is not as simple as that. It will take a long time. Let’s wait…..!
