Beijing, July 26, 2017: Chinese researchers have developed a user-interactive electronic skin that can change colour — an ability associated with animals such as chameleons, octopuses and squid. The changes are perceptible to the human eye without much strain.
Though science has been able to replicate these abilities with artificial skin, the colour changes are often only visible to the naked eye when the material is put under huge mechanical strain.
The research conducted by Tsinghua University in Beijing can have applications in robotics, prosthetics and wearable technology.
“This user-interactive e-skin should be promising for applications in wearable devices, robots and prosthetics in the future,” the study mentioned.
The researchers employed flexible electronics made from graphene, in the form of a highly-sensitive resistive strain sensor, combined with a stretchable organic electrochromic device.
“To obtain good performance with a simple process and reduced cost, we designed a modulus-gradient structure to use graphene as both the highly sensitive strain-sensing element and the insensitive stretchable electrode of the ECD layer,” said Tingting Yang from Tsinghua University, in a paper published in the journal 2D Materials.
The researchers found that subtle strain — between zero and 10 per cent — was enough to cause an obvious colour change, and the RGB value of the colour quantified the magnitude of the applied strain.
The study noted that the capability for interactive colour changes with such a small strain range has been rarely reported before. (IANS)
Jaipur, Jan 27, 2017: Population control, a vital goal for both China and India, can be better achieved by empowering women instead of coercive methods like Beijing’s “one-child” drive, says acclaimed journalist Mei Fong who has extensively studied the policy and its deleterious demographic and economic effects.
“Chinese and Indian societies, both of which are patriarchal, must realise that marriage and giving birth to babies (preferably male) is not the sole purpose of women, nor desirable early.
“Allowing women choice as to their education, jobs and methods of contraception is more viable for controlling population, rather than forced and ‘quick-fix’ methods like sterilisation, abortions and quotas,” the Pulitzer Prize-winning Malayasian Chinese-American journalist told IANS in an interview.

Fong, who covered China for the Wall Street Journal and has authored “One Child: The Past and Future of China’s Most Radical Experiment” (One World/Pan Macmillan, 2016), listed the several severe and unwelcome outcomes of the policy, begun in 1979 as China under Deng Xiaoping tried to accelerate economically.
“It has led to a severe gender imbalance… there are many ‘villages of bachelors’ across China, there is lack of care for the elderly, and a falling birth rate, which will impact on the workforce China needs to remain a low-cost global manufacturing hub,” said Fong, who addressed a session at the Jaipur Literature Festival 2017.
Then the “Little Emperors”, or boys who were born under the policy — with Chinese no less keen than Indians on a male child — have a different mindset, she said. “They have received so much adoration… this can stifle innovation and entrepreneurship.”
Their parents, keen to get them a good match, have got them apartments to increase their attraction, leading to an artificial high in urban estate prices throughout China, she added.
On the other hand, though the lesser number of women are eagerly sought after, this has not made a difference in their status.
“The laws of economics do not work in a patriarchal system… women are more valuable, but not valued. They have been commodified and this fuels sex trafficking.”

Though Chinese authorities had relaxed the policy as her book was getting ready in 2015 and now had a two-children norm, “women’s fertility was not a tap that could be turned off and on” and it was going to take long for the adverse effects to be mitigated, Fong told IANS.
It has led to a “strange role reversal” where the Chinese are going to America for babies, since it has better medical facilities and allows surrogate parenting.
She also cited the traumatic and bizarre circumstances that she had come across while researching the book, including a woman who was one of the “population police” reporting illicit pregnancies and involved in almost 1,500 forcible abortions including third in late stages of pregnancy, but herself having only a daughter and needing to adopt a son.
“This woman now lives abroad in hiding and her favourite pastime is giving candy to children,” she said.
She also recounted the case of a Chinese company once making furniture but now not finding it viable and switching to making full-size sex dolls. “They ship them out in coffin-like boxes… it is creepy,” she said.
Fong also told IANS that there were many other “explosive stories” of traumatic experiences of the one-child policy, which she faulted as being based on a “faulty mindset” of all men deciding a policy for women, and going on so long without a course correction.
“They thought women’s fertility was a machine that could be speeded up or down… whether more humane policies, though taking a little longer, but less coercive, would have achieved the same purpose with lesser side-effects,” she said, adding the worst is that is that it was not the policy, but relaxing of socialist controls, that led to China’s economic boom.
“Government social policies can work. The problem is when fast results are sought,” said Fong. (IANS)
Beijing, Jan 11, 2017: China will not sit quietly if India boosts military ties with Vietnam to counter Beijing, a Chinese newspaper warned on Wednesday.
An op-ed in Global Times also told New Delhi not to “stir up troubles” in Southeast Asia.
“If the Indian government genuinely treats its enhancement of military relations with Vietnam as a strategic arrangement or even revenge against Beijing, it will only create disturbances in the region and China will hardly sit with its arms crossed,” said the daily which is said to represent the views of the Chinese leadership.
According to reports, India is in talks with Vietnam to sell indigenous surface-to-air missile system.

“This was supposed to be a normal arms sale, yet was portrayed by the Indian media as a response ‘to counter the Chinese threat.'” the daily said.
It said it was natural for New Delhi to deepen its ties with Hanoi, which is a pillar of India’s Act East Policy.
It, however, cautioned that “such ties should be built for the sake of peace and stability in the region, rather than stirring up troubles or anxiety for others.
“However, when India and Vietnam are in talks about possible sales, New Delhi seems to keep taking a sneak peak at Beijing, as if the deal is stealthily aimed at China.”

During an official visit to Hanoi in September 2016, Prime Minister Narendra Modi announced $500 million defence credit line to Vietnam, which is dubbed as “principal protagonist,” in the South China Sea –claimed by Beijing.
It said Indian experts and media describing Vietnam as China’s backyard reflected “India’s outdated diplomatic mindset”.
The article said “due to geopolitical factors, some nations have been cosying up to India over the years, which to a large extent contributed to India’s fruitful development.
“New Delhi understands that the best strategy for itself is to continue its collaboration with all parties, instead of picking a side and turning hostile to one another.
“Otherwise, it might not only turn others’ troubles to its own puzzles, but also suffer enormous losses of development opportunities.
“India has a dream to grow into a great power. But under today’s international circumstances, it will be extraordinarily hard to achieve the goal on its own.
“What India needs is more pragmatic cooperation with other countries.”
The newspaper, run by the China’s Communist Party, hoped that India will join the Belt and Road project.

“This will help promote the country’s infrastructure construction, improve connectivity within the region and may even turn into a push to solve the India-Pakistan contradictions.”
India has been non-committal to China’s ambitious project. New Delhi has opposed the China Pakistan Economic Corridor, which passes through Pakistan-administered Kashmir claimed by India.
“It is hoped that the hype in the Indian media does not represent the country’s government. There are divergences between Beijing and New Delhi, yet there are more common interests that await the two to explore.” (IANS)
