New organic nano-wires may help replace silicon in computer chips

Organic nano-scale wires may serve as an alternative to silicon in computer chips, according to a collaborative team of Chinese and Danish researchers.

Nanochemists from the Chinese Academy of Sciences and the Nano-Science Center, Department of Chemistry at the University of Copenhagen, say that they have created nanoscale electric contacts out of organic and inorganic nanowires.

The researchers say that they have crossed the wires like Mikado sticks in the contact, and coupled several contacts together in an electric circuit.

They say that doing so has enabled them to produce prototype computer electronics on the nanoscale.

Presently, the foundation of our computers, mobile phones and other electronic apparatus is silicon transistors.

A transistor is in principal an on- and off- contact, and there are millions of tiny transistors on every computer chip.

Thomas Bjornholm, Director of the Nano-Science Center, Department of Chemistry at University of Copenhagen said: "We have succeeded in placing several transistors consisting of nano-wires together on a nano device. It is a first step towards realisation of future electronic circuitry based on organic materials - a possible substitute for today's silicon-based technologies. This offers the possibility of making computers in different ways in the future."

The researchers have revealed that the material developed by them has a low operational current, high mobility and good stability, the qualities that can enable it to compete with silicon.

Excited over the results, Professor Wenping Hu, of Chinese Academy of Sciences, said: "This work is the first significant result of our collaboration with the researchers from the Nano-Science Center. It is a good starting point for our new Danish-Chinese research centre for molecular nano-electronics and it underlines the fact that we can complement each other and that together we can achieve exciting and important results."

A research article describing the study has been published in the journal Advanced Materials.

ROTI, KAPDA, MAKAAN & MOBILE.....

As part of her Garibi Hatao campaign for the 1971 Lok Sabha polls, Mrs Gandhi had promised roti, kapda and makaan to every poor Indian, a slogan that won her a famous election victory but this slogan needs a change in modern India, it should be Roti, kapda, makaan & mobile. Apart from basic needs like roti kapada and makaan, mobile became essential and basic need in every once life. Every one from house maid, rickshaw puller, taxi drivers, office boys etc, from common man to elite people are using mobile phone for communication. The cost of mobile starts from modest Rs 3000 to billions (platinum and diamondstudded).

Communication among people is most important. With the invention of telephone, people used to talk and communicate to long distances. With advent of mobile phone the entire concept of communication is completely changed. The world became one. Earlier mobile phone was luxury and now it is necessity. According to survey nearly 30 crores of people are using mobile phone. It is estimated by 2010 nearly 25 crores of people use mobile phones having internet and camera facility. The largest mobile users in the world is China, next comes to India. The market share of Nokia is 52.8%, followed by 10.2% LG and 8.3 % Samsung.

According to Ravindra H Dholakia “Things started changing rapidly from the eighties with decontrol and deregulation of the economy. Indian consumers started realizing more and more value for their money as economic reforms progressed and goods and services of greater variety and better quality became available in the market. Freer and newer markets established consumer sovereignty; incomes and production started rising rapidly and absolute poverty began to decline. Consumer spending on basics fell to 73% in 1991, 62% in 2001, and 55% in 2008, making more room for spending on comforts and luxuries. Transport, communication, education, recreation, and personal and business services that accounted for 15% of consumer spending in 1981 rose sharply to more than 35% in 2008. This shows the rise in the value for consumers' money in effective terms. Moreover, household savings in GDP also sharply rose to about 12% in 2008, while basic necessities accounted for only 30%. Financial assets like net deposits, shares, debentures, life insurance, and provident and pension funds that constituted hardly 11% of household savings in 1951 now account for more than 43% in 2008. Concern and provision for future consumption is also showing a sharp increase”

Country will have 3000 million mobiles by 2010. Every individual is having more purchasing power and spending more money on mobiles and other consumable items. The consumer is adding lot of E- waste to the planet. Consumerism is harming environment. Mobile became essential part of life like roti kapada, and makaan.

The new slogan ROTI KAPADA, MAKAAN AND MOBILE is appropriate to modern man.

POP KING MICHAEL JACKSON IS EVER GREEN HERO

The pop king Michael Joseph Jackson is no more. He has made impact with his pop music in all age groups of people all over world. For his legions of fans, he was the peter pan of pop. In the early 1980s, he became a dominant figure in popular music and the first African American entertainer to amass a strong crossover following on MTV. The popularity of his music videos airing on MTV, such as "Beat It", "Billie Jean" and "Thriller—widely credited with transforming the music video from a promotional tool into an art form—helped bring the relatively new channel to fame. Videos such as "Black or White" and "Scream" made Jackson an enduring staple on MTV in the 1990s. With stage performances and music videos, Jackson popularized a number of physically complicated dance techniques, such as the robot and the moonwalk. His distinctive musical sound and vocal style influenced many hip hop, pop and contemporary R&B artists. Michael Joseph Jackson (August 29, 1958 – June 25, 2009) was an American recording artist and entertainer. The seventh child of the Jackson family, he made his début onto the professional music scene at the age of 11 as a member of The Jackson 5 in 1969, and began a solo career in 1971 while still a member of the group. Jackson was referred to as the "King of Pop"in subsequent years; his 1982 album Thriller is the world's best-selling record of all time and four other solo studio albums are also among the world's best-selling records: Off the Wall (1979), Bad (1987), Dangerous (1991) and History (1995). Jackson donated and raised millions of dollars for beneficial causes through his foundation, charity singles and support of 39 charities. Other aspects of his personal life, including his changing appearance and behavior, generated significant controversy, damaging his public image. Though he was accused of child sexual abuse in 1993, the criminal investigation was closed due to lack of evidence and Jackson was not charged. The singer had experienced health concerns since the early 1990s and conflicting reports regarding the state of his finances since the late 1990s. Jackson married twice and fathered three children, all of which caused further controversy. In 2005, Jackson was tried and acquitted of further sexual abuse allegations and several other charges. One of the few artists to have been inducted into the Rock and Roll Hall of Fame twice, his other achievements include multiple Guinness World Records—including one for "Most Successful Entertainer of All Time"—13 Grammy Awards, 13 number one singles in his solo career, and the sale of 750 million records worldwide. Jackson's highly publicized personal life, coupled with his successful career, made him a part of popular culture for almost four decades. Michael Jackson died on June 25, 2009, aged 50. Before his death, Jackson had announced a 50-date sell-out This Is It comeback tour, in London, England. Even though he is no more, he lives in every heart of his fans. The pop king Michael Joseph Jackson is ever green hero.

VALENTINE DAY: MUCH ADO ABOUT NOTHING.

Valentine's Day started in the time of the Roman Empire. In ancient Rome, February 14th was a holiday to honour Juno. Juno was the Queen of the Roman Gods and Goddesses. The Romans also knew her as the Goddess of women and marriage. There are varying opinions as to the origin of Valentine's Day. Some experts state that it originated from St. Valentine, a Roman who was martyred for refusing to give up Christianity. He died on February 14, 269 A.D., the same day that had been devoted to love lotteries. Legend also says that St. Valentine left a farewell note for the jailer's daughter, who had become his friend, and signed it "From Your Valentine". Other aspects of the story say that Saint Valentine served as a priest at the temple during the reign of Emperor Claudius. Claudius then had Valentine jailed for defying him. In 496 A.D. Pope Gelasius set aside February 14 to honour St. Valentine. The lives of young boys and girls were strictly separate. However, one of the customs of the young people was name drawing. On the eve of the festival of Lupercalia the names of Roman girls were written on slips of paper and placed into jars. Each young man would draw a girl's name from the jar and would then be partners for the duration of the festival with the girl whom he chose. Sometimes the pairing of the children lasted an entire year, and often, they would fall in love and would later marry. Gradually, February 14 became the date for exchanging love messages and St. Valentine became the patron saint of lovers.

The date was marked by sending poems and simple gifts such as flowers. There was often a social gathering or a ball. Many view this day as harmless fun, an opportunity to show love and affections towards spouses and partners by exchanging cards, giving flowers and having candle lit dinners etc. The old tradition of love on Valentine ’s Day became multibillion dollar business. With modernity young people celebrate this festival. The greeting shops like Archies will make big business. The tradition of valentine day which symbolises love became controversy in India and abroad. Some Hindu and some Muslim religious groups openly opposing the valentine day saying that this not the culture of the country.

I feel that, with change of time there will changes in culture of any country. Modern days one has to accept things as long as valentine day is celebrated with dignity and decent way of showing love towards partner. These things should not be treated by religious groups as bad things. Every religion has taught love towards partner. How can one say that celebrating festival of love is uncultured? If anyone shows the vulgarity it should be questionable!!!! By any one.

OBAMA SETTING EXAMPLE TO THE WORLD.

Barack Obama ha taken over reins of USA. He has done campaign to “change America and bring Change in American administration and economy."Americans have sent a message to the world," "If there is anyone out there that still doubts that America is a place where all things are possible... who still questions the power of our democracy, tonight is your answer." What are the challenges to new president •His first task is to revive economy of USA, economy is in a grip of recession •Subprime crisis, every American wants a shelter and the prices housing sector should not fall any t more. •The greatest three trillion war with Iraq, which is the tax payer money America has spent on Iraq war. Withdrawing of troops from Iraq. •Energy crisis, USA is biggest consumer of energy and it has not signed Kyoto Protocol,(Climate Change) many American wants that USA should go to green technology and save the energy and sign the Kyoto protocol. •Control of terrorism is one more problem the new president may face. •Tackling of unemployment problem and out sourcing is some more big issues. •We have to see Americans who have elected an immigrant and half Muslim to the white house. Immediately after taking over office Obama has said he will give conditional aid to the Pakistan for controlling of terrorism and closing of Guatemala prison with in a year.The representatives have passed $819-billion stimulus package for helping the industry, individuals etc. He has taken policy decision on climate change “We will make it clear to the world that America is ready to lead, from being held hostage" to hostile regimes and the threat of global warming. To protect our climate and our collective security, we must call together a truly global coalition”. Obama has pulled American elite especially the wall street CEO for getting the hefty bonus when the companies are helped by the government on bailout package and he also pulled the citigroup for ordering jet plane when country is facing recession. He has said it is shameful and irresponsible. He is no doubt the peoples president. Obama should ask industry to set the salary structure so that the gap between rich and poor will not be wide.

He is setting standards to the world leaders that he means business and see the welfare of common American when USA is facing economic crisis.
