Dec. 11, 2012 ? Rose madder -- a natural plant dye once prized throughout the Old World to make fiery red textiles -- has found a second life as the basis for a new "green" battery.
Chemists from The City College of New York teamed with researchers from Rice University and the U.S. Army Research Laboratory to develop a non-toxic and sustainable lithium-ion battery powered by purpurin, a dye extracted from the roots of the madder plant (Rubia species).
More than 3,500 years ago, civilizations in Asia and the Middle East first boiled madder roots to color fabrics in vivid oranges, reds and pinks. In its latest technological incarnation, the climbing herb could lay the foundation for an eco-friendly alternative to traditional lithium-ion (Li-ion) batteries. These batteries charge everything from your mobile phone to electric vehicles, but carry with them risks to the environment during production, recycling and disposal.
"Purpurin," on the other hand, said team member and City College Professor of Chemistry George John, "comes from nature and it will go back to nature." The team reports their results in the journal Nature's online and open access publication, Scientific Reports, on December 11, 2012.
Most Li-ion batteries today rely on finite supplies of mined metal ores, such as cobalt. "Thirty percent of globally produced cobalt is fed into battery technology," noted Dr. Leela Reddy, lead author and a research scientist in Professor Pulickel Ajayan's lab in the Department of Mechanical Engineering and Materials Science at Rice University. The cobalt salt and lithium are combined at high temperatures to make a battery's cathode, the electrode through which the electric current flows.
Mining cobalt metal and transforming it, however, is expensive, Dr. Reddy explained. Fabricating and recycling standard Li-ion batteries demands high temperatures, guzzling costly energy, especially during recycling. "In 2010, almost 10 billion lithium-ion batteries had to be recycled," he said .
Production and recycling also pumps an estimated 72 kilograms of carbon dioxide -- a greenhouse gas -- into the atmosphere for every kilowatt-hour of energy in a Li-ion battery, he noted. These grim facts have fed a surging demand to develop green batteries, said Dr. Reddy.
Fortunately, biologically based color molecules, like purpurin and its relatives, seem pre-adapted to act as a battery's electrode. In the case of purpurin, the molecule's six-membered (aromatic) rings are festooned with carbonyl and hydroxyl groups adept at passing electrons back and forth, just as traditional electrodes do. "These aromatic systems are electron-rich molecules that easily coordinate with lithium," explained Professor John.
Moreover, growing madder or other biomass crops to make batteries would soak up carbon dioxide and eliminate the disposal problem -- without its toxic components, a lithium-ion battery could be thrown away.
Best of all, purpurin also turns out to be a no-fuss ingredient. "In the literature there are one or two other natural organic molecules in development for batteries, but the process to make them is much more tedious and complicated," noted Professor John.
Made and stored at room temperature, the purpurin electrode is made in just a few easy steps: dissolve the purpurin in an alcohol solvent and add lithium salt. When the salt's lithium ion binds with purpurin the solution turns from reddish yellow to pink. "The chemistry is quite simple," coauthor and City College postdoctoral researcher Dr. Subbiah Nagarajan explained.
The team estimates that a commercial green Li-ion battery may be only a few years away, counting the time needed to ramp up purpurin's efficiency or hunt down and synthesize similar molecules. "We can say it is definitely going to happen, and sometime soon, because in this case we are fully aware of the mechanism," said Professor John.
"When you can generate something new or unheard of, you think of chemistry in a different way," he added. "That a natural material or dye can be used for a battery, that is exciting, even for me."

?Yes, I?m frustrated,? he told me. ?If Romney was in the White House and Republicans had control of the Senate, I would have had a chance to advance positive ideas, so there would have been a very different scenario.? But that?s just not the case. DeMint explained that he believes ?it?s an important role in the Senate to be here and try to stop bad legislation when you?re in the minority,? but the election results made clear that conservatives face more urgent problems.
DeMint said many people were shocked that a U.S. senator would give up his seat. But given today?s political situation, he believes he will have greater influence ? not just on the public debate generally but specifically on the Senate ? from the outside. ?I won?t be taking votes, but I guarantee you I will affect more votes at the Heritage Foundation than I do in the Senate.?
DeMint?s move is an enormous break with tradition in his native South Carolina. Predecessors Strom Thurmond and Ernest Hollings served a total of 85 years in the Senate and retired at ages 100 and 83, respectively. DeMint is 61 and has served in the Senate just since January 2005. He is leaving two years into a six-year term; certainly some South Carolinians who voted for him are unhappy about that. ?People in South Carolina knew I wasn?t going to make this a career,? DeMint told me. ?A lot of them didn?t like it when I said I was going to leave the House after six years, and I announced after the last election that I wasn?t going to run again. I would not leave the Senate unless I thought I could serve South Carolina better at the Heritage Foundation.?
That?s the frustration again. Facing defeat after defeat in a situation in which the most he could do was stop some bad things from happening, DeMint didn?t see much conservative vigor among his colleagues. ?I just believed that Republicans have not been reliable partners of the conservative cause,? he said. ?I think there is a lack of vision and boldness that we need at the national level. I?m not pointing to anyone in particular, but it?s been a long time since I?ve been in a conservative conference where someone stood up and just inspired people with a message of what we really stand for and what America needs at this point.?

Jada Pinkett Smith Addresses The Problems Facing Today?s Women And Men In Relationships
Jada Pinkett Smith has obvious concerns about the state of relationships between men and women nowadays and has posted a long blog to her?Facebook page?to address them.? In her latest post, Jada talks about how the true inner beauty of a woman over time has taken a backseat to superficiality of ?weaves and?red bottom shoes,? while men use?money?as a status symbol and as a way of buying love. Jada also believes that?women today have no voice and have been reduced to being just pleasure toys. She states that our culture promotes women looking good without saying anything meaningful, and men have become so frustrated with insecurity that it often leads to domestic violence in?the home.? Jada also says if one person in the relationship is lost, then the entire union is doomed because the couple are supposed to balance each other out..
Step into her blog below:
The war on men through the degradation of woman.
How is man to recognize his full self, his full power through the eye?s of an incomplete woman? The woman who has been stripped of Goddess recognition and diminished to a big ass and full breast for physical comfort only. The woman who has been silenced so she may forget her spiritual essence because her words stir too much?thought outside of the pleasure space. The woman who has been diminished to covering all that rots inside of her with weaves and?red bottom shoes.
I am sure the men, who restructured our societies from cultures that honored woman, had no idea of the outcome. They had no idea that eventually, even men would render themselves empty and longing for meaning, depth and connection. There is a deep sadness when I witness a man that can?t recognize the emptiness he feels when he objectifies himself as a bank and truly believes he can buy love with things and status. It is painful to witness the betrayal when a woman takes him up on that offer. He doesn?t recognize that the create of a half woman has contributed to his repressed anger and frustration of feeling he is not enough. He then may love no woman or keep many half women as his prize. He doesn?t recognize that it?s his submersion in the imbalanced warrior culture, where violence is the means of getting respect and power, as the reason he can break the face of the woman who bore him four children.
When woman is lost, so is man. The truth is, woman is the window to a man?s heart and a man?s heart is the gateway to his soul.
Power and control will NEVER out weigh love.
May we all find our way.
J
Deep.

For all of the bluster, there was never really any doubt this would get done: the Dodgers signed Korean left-hander Hyun-Jin Ryu just before the Sunday afternoon deadline.
CBSSports.com?s Jon Heyman reports that it?s a six-year, $36 million contract that includes an opt out after five years if Ryu tops a certain number of innings.
The Dodgers bid $25.7 million for Ryu?s rights last month after he was posted by his team in Korea. He went 9-9 with a 2.66 ERA and 210 strikeouts in 182 2/3 innings for Hanwha last season.
The 25-year-old Ryu can?t necessarily be penciled into a rotation that?s set to include Clayton Kershaw, Zack Greinke and Josh Beckett, with Chad Billingsley and Ted Lilly coming back from injuries. The team also has Chris Capuano and Aaron Harang available as starters, but with a payroll set to come in around $250 million, those guys are expendable.
Ryu could open the year in the pen and then move into the rotation later, or it?s possible he?ll be needed right away if either Billingsley or Lilly requires additional rehab time. Given that Ryu hasn?t thrown 200 innings in a season since 2007, it might be for the best if he spends the first month or so working in relief.
Here?s some Korean footage of Ryu striking out 13 batters in a game:

KOLKATA: The task force on urban infrastructure that was set up by chief minister Mamata Banerjee recently to look into the problems of developers will hold its first meeting in the state assembly on Monday.
The chief secretary and ministers and secretaries of the finance, industries and urban development departments are members of the task force and will report to the state cabinet committee on infrastructure.
Representatives of the construction-builder community have also been invited to be a part of Monday?s meeting for chalking out plans to develop urban infrastructure.
Sources said the meeting could focus on the Urban Land Ceiling Act. Real estate firms have in fact been demanding that the act be abolished in the state, like in the entire country. The issue was raised at the Bengal Builds conclave and developers had said that it was acting as an obstacle to invest in real estate projects in Bengal.
Besides, the problem of syndicate raj may also come up for discussion at the meeting. Mamata had earlier expressed her displeasure over such syndicates. Hidco authorities had also held meetings with police to crack down on the operators of these syndicates. But the problem continues to plague developers, especially in areas like Rajarhat New Town.
In order to allow developers more built-up space, the state government is also planning to increase the floor area ratio (FAR). The issue of revising and increasing the FAR is under consideration in the state cabinet.
The task force on urban infrastructure, that was announced by chief minister Mamata Banerjee for looking into the problems faced by developers while inaugurating the Bengal Builds conclave recently is scheduled to hold its first meeting on Monday in the state assembly.
The ministers of finance, industries and urban development as well as the chief secretary and concerned department secretaries are members of the task force. Members of the construction-builder community are also being invited in the meeting to chalk out a plan for developing urban infrastructure. The task force would report to the state cabinet committee on infrastructure.
Highly placed officials said that discussion could take place on the urban land ceiling Act. Real estate firms have been demanding that the Act should be do away with, as it has been abolished in the entire country and that Bengal was the only state to still have the Act. Developers said that the Act was acting as a major obstacle to construct big real estate projects in the state. The issue was raised at the Bengal Builds conclave.
Also, discussions could be held on the syndicate raj that has been creating problems for developers, particularly in Rajarhat New Town. Recently, a syndicate trouble was again reported from the area. Chief minister Mamata Banerjee had earlier said that syndicate raj will not be tolerated by any means. Hidco authorities had earlier held a high level meeting with the police on the issue and the police had started operations to crackdown this syndicate raj, but the matter is still going on, particularly in Rajarhat where several multi storied buildingss are being constructed.
The state government is also planning to increase the floor area ratio (FAR) to allow developers to have more build up space. Several highrise buildings are coming up in Rajarhat New Town and also in places in the Kolkata mteropolitan area surrounding the city. The issue of revising and increasing the FAR for the entire state is under consideration in the state cabinet and the proposal may be passed very soon.
