Indian-origin physicist Madhu Menon, discovers material better than graphene
New York, (IANS) An Indian-origin scientist has developed a new one atom-thick flat material that could upstage the wonder material graphene for having properties allowing it to be used in advance digital technology.
Discovered by Madhu Menon, physicist at the University of Kentucky in the US, the new material is made up of silicon, boron and nitrogen – all light, inexpensive and abundant elements. The material is stable, a property many other graphene alternatives lack.
“We used simulations to see if the bonds would break or disintegrate – it didn’t happen. We heated the material up to 1,000 degree celsius and it still didn’t break,” said Menon, physicist in the centre for computational sciences. The discovery is reported in a paper in Physical Review B.
Using state-of-the-art theoretical computations, Menon and his collaborators demonstrated that by combining the three elements, it is possible to obtain a one atom-thick, truly 2D material with properties that can be fine-tuned to suit various applications beyond what is possible with graphene.
Menon’s colleagues were Ernst Richter from Daimler in Germany and Antonis Andriotis from Institute for Electronic Structure and Laser (IESL) in Greece.
While graphene is touted as being the world’s strongest material with many unique properties, it has one downside: it isn’t a semiconductor and therefore disappoints in the digital technology industry.
The three elements forming the new material all have different sizes; the bonds connecting the atoms are also different.
As a result, the sides of the hexagons formed by these atoms are unequal, unlike in graphene.
The new material is metallic but can be made semiconducting easily by attaching other elements on top of the silicon atoms.
“We know that silicon-based technology is reaching its limit because we are putting more and more components together and making electronic processors more and more compact,” Menon said adding “but we know that this cannot go on indefinitely; we need smarter materials.”
He said they were anxious for this to be made in the lab. “The ultimate test of any theory is experimental verification, so the sooner the better!” Menon added in a paper.
This discovery opens a new chapter in material science by offering new opportunities for researchers to explore functional flexibility and new properties for new applications.

Joint statement from the Greater Toronto Area & Hamilton Mayors and Chairs
We are united in fighting COVID-19 – protecting our residents and saving lives.
While the measures we have taken to stop the spread of the virus have made a difference, this virus has still taken far too many lives in our communities and continues to threaten the lives of our residents.
At the same time, there is no denying the devastating impact of COVID-19 on the economy. Jobs have been lost, many businesses have closed or are at risk of closure, and many families are worried about their financial future.
We’ve been hit hard but that’s why it is so important that we keep moving forward and come back as strong as possible.
Today, the GTHA Mayors and Chairs met to discuss the impacts of COVID-19 on the region and how our municipalities can work together on the economic restart and recovery.
We know the Toronto Census Metropolitan Area alone is projected to lose 355,000 jobs and 28% of GDP along with $894 million in lost wages and $3.7 billion in revenue losses for businesses. This will be felt right across the GTHA but it also threatens the provincial and national economies.
A strong recovery right here in the GTHA is crucial to healing the economic damage done by COVID-19 and helping the families and businesses all governments have been working to protect throughout this emergency.
Ontario’s economy and Canada’s economy need the GTHA to come back stronger than ever when the restart begins.
We are determined to deliver this recovery and we agreed today that the GTHA municipalities will be working together to successfully and smoothly reopen our vital regional economy when the time comes.
We also discussed how we can in a consistent way achieve significant, necessary financial support from the other governments to help mitigate the impact of COVID-19 and protect our ability to contribute to the recovery. A strong recovery needs strong cities and regional governments.
We have agreed we will work together to share information about our respective financial positions and explore together measures we can advocate to the other governments which will help to ensure the financial stability of local and regional governments in the GTHA.
Our child care and recreation programs help parents get back to work.
Our emergency services keep people safe.
Our transit systems get people to work and home safely.
Our major infrastructure projects – often built in conjunction with the other governments – will help kick-start the recovery and create countless jobs.
Our economic development activities attract jobs and investment.
We built a strong and vibrant GTHA and we know that we will need to come back even stronger and as quickly as we can in order to keep Canada’s economy going.
With the cooperation and support of the provincial and federal governments, we are ready to rise to this challenge.”

Justin Trudeau in India: Hug missing! Mounting pressure?
The much publicized and anticipated visit of Prime Minister Justin Trudeau to India was marred with questions. The questions were centered on the kind of welcome he would be given in the Sikh dominated state of Punjab. Also the famous hug by Indian Prime Minister Narendra Modi was being anticipated. Prime Minister Justin Trudeau finally made his much-touted visit to India. He landed on the Indira Gandhi Airport, New Delhi only to be received by Gajendra Singh Shekhawat not even a Cabinet Minister in Narendra Modi’s government.
He is presently the second rank Minister of State for Agriculture. That comes in complete contrast to the warmth that Prime Minister Narendra Modi and his NDA government has generally displayed towards the visiting dignitaries. Only a couple of weeks ago, when the heads of the 10 ASEAN states arrived in India, Prime Minister Narendra Modi didn’t receive Prime Minister Justin Trudeau at the airport, as he has previously done with many leaders including Barack Obama, Xi Jinping, Shinzo Abe, and Benjamin Netanyahu.
The fact that Prime Minister Narendra Modi didn’t join him is all surprising even when Prime Minister Trudeau visited Gujarat. This is unusual because the Indian Prime Minister has set a trend that he always accompanies head of the state when they visit his home state.
Even Chief Minister of Uttar Pradesh Yogi Adityanath did not show up, let alone accompany Prime Minister Trudeau to the Taj. However, during Israeli Prime Minister Netanyahu’s 15 January visit to the Taj Mahal at Agra, Yogi Adityanath had received Netanyahu and his wife and shown them around as well as hosted a lunch for them. For first three days, none from the executive or the elected representative held any meeting with the delegation.
Media in India is trying to spread a message that the cold treatment given by Prime Minister could be because two of the four Sikh members of Trudeau’s cabinet – Harjit Sajjan and Amarjeet Sohi – support the Khalistan movement. However, had that been the case his visit to Punjab would have got a similar response. However, the Punjab Government led by Captain Amarinder Singh rolled out a red carpet during his stay at Amritsar and even the two leaders held some fruitful discussions.
Thus putting an end to those criticisms that that Prime Minister Trudeau’s visit was devoid of any warmth. Chief Minister of Punjab Amarinder Singh, for instance who met Prime Minister Justin Trudeau setting aside his earlier prejudice that he exhibited during the visit of Defence Minister Harjeet Singh Sajjan.
In recent months, Gurudwaras (Sikh temples) in Canada, the United States and Australia have banned Indian officials from visiting gurudwaras and the moment started with Gurudwaras here in Toronto. Could that be the reason for Prime Minister Narendra Modi to not accord one of the warmest welcomes that he is known to provide? Or the use by Canada’s parliament of the term genocide to describe mass killings of Sikhs in India in 1984 has left the Indian Prime Minister disturbed? However, more than Prime Minister Modi, this could have left the Congress party in troubled waters, but that was also not the case as Amarinder Singh hails from the same party.
The lukewarm welcome to Prime Minister Trudeau can have its political ramifications too. Will it hamper the significant 2015 deal, in which Canada agreed to supply 3,000 metric tons of Uranium to power India’s atomic reactors?
Somewhere Prime Minister Modi has not taken the issue of non allowing entry of Indian officials to Gurudwaras and the statement on Genocide too lightly. Prime Minister Modi however has failed to understand that Canada cannot curtail the right of freedom of speech and expression of its citizen.
Two nations perhaps failed to resolve the matter before Prime Minister boarded the flight from Canada and not welcoming Prime Minister Trudeau could be a tactical decision to put pressure on him. With Prime Minister Modi preferring to meet him at the far end of the tour has conveyed a lot about the myopic approach of Prime Minister Modi.
