SODIUM EMBEDDED CARBON INVENTED

07 Jan 17

The presence of a little sodium in carbon-based energy technology enhances the performance of electrodes by two-folds than that of the three-dimensional graphene which is currently in use. A new research conducted at Michigan Technological University by Yun Hang Hu, professor of materials science and engineering, and his team has developed a brand-new method of synthesizing sodium-embedded carbon nanowalls. This was recently published in the journal Nano Letters.

In case of metal-doped carbon, the metals simply adhere to the surface of the carbon and get oxidized easily. But, in sodium-embedded carbon, the carbon structure protects the sodium metal. This dream metal was created by a temperature-controlled process that resulted in a black carbon powder with trapped sodium atoms.

Further, in collaboration with the scientists at the University of Texas and University of Michigan, they established that the sodium was embedded inside the carbon structure, and not just adhered to it. They then tested their invention in several energy devices. It was found that it performed far better than graphene in super-capacitors and dye-sensitized solar cells.

Scientist Hu envisions sodium-embedded carbon to have a bright future as it offers improvements in batteries, solar tech, super-capacitors, and fuel cells.

Ever Heard of Laissez – Faire Leadership?

15 Dec 17

The Laissez – faire leadership is also known as delegate leadership style. It is a type of leadership style in which leaders do not interfere and allow group members to make decisions. Researchers have studied that this style of leadership leads to the lowest productivity among group members. Still, one has to understand both benefits and pitfalls of such leadership style.

This style works excellent when the team members have skills to succeed. The team members are able to deal with any issue through their expert skills. Laissez – Faire is a style which allows team members to feel free and stay satisfied with their work. Thus, independence is valued and followers have a high – level of passion and intrinsic motivation towards their work. The downsides of Laissez – Faire leadership can sometimes prove to be very dangerous. It is not ideal when group members lack knowledge or experience. It can lead to low accountability, passivity and avoidance. Therefore, use this kind of leadership wisely to ensure growth of anything.

Climate Migration Demands International Attention

14 Dec 17

Climate Change is a human rights issue. In 2016, extreme weather, climate conditions displaced approximately 45 people every minute. This issue is in immediate need of action. As a result, civil leaders from more than 100 countries across the world, have urged for an action on the displacement caused due to climate change at a summit in Suva, Fiji. They suggested the international community to defend the human rights of the victims of such displacement.

Climate change should be identified as a major cause for migration in the global compact due to be negotiated by countries in 2018, such as Oxfam Pacific, 350.org and Act Alliance. Certain instances of climate migration are (i) sea level rise in the pacific, making some island communities unviable; (ii) 2 kilometres inland movement of Vunidogoloa in Fiji, in 2014, leading to relocation of 30 villages. There are well framed international rules for giving asylum to victims of political persecution but no provision for people displaced by climate change. It has been seen that initiatives in this regard have been made by New Zealand, due to its longstanding relationship with a number of Pacific islands. It is planning to create world’s first humanitarian visas. These visas shall be employed towards people displaced due to climate changes. There is need for other countries also to enforce such actions. But in reality, only vulnerable countries are eager to discuss the subject during climate negotiations, others often focus on different priorities.

The Connection Between Our Inner Voice and Self Conversation

13 Dec 17

Our brain does a number of different functions at the same time. According to a new study talking to ourselves may be fundamentally the same as speaking our thoughts out loudly. The latest results found by the researchers may help us understanding and getting the reason why people with mental illnesses hear voices to themselves.

Earlier it was thought that auditory-verbal hallucinations arise due to abnormalities in inner speech that is our silent internal conversation. Past research suggested that when we are ready to speak out loudly, our brain develops an exact copy of the instructions. After that, in no time these instructions are sent to lips, mouth and vocal cords and the process is known as an efference-copy. It is sent to the region of the brain that processes sound to forecast what sound it is about to listen. Then the region allows the brain to differentiate between the predictable sounds and the less predictable sounds. The way our brain perceives sounds can be changed by People's own thoughts. As its effect when people imagine sounds, those sounds seemed quieter comparatively to the real one. This research is going to be helpful in understanding how inner speech might be different in people with psychotic illnesses such as schizophrenia. It will help doctors to cure those patients well.

India’s Critical Position in the Export Sectors

12 Dec 17

The 5-year foreign trade policy (FTP) (2015-20) was issued to provide a framework for generating employment and increasing value addition. It also aimed at increasing the exports of goods and services to $900 billion by 2020. The mid- term review of this policy by the government has provided a relief to the Indian exporters. During the review, the government declared liberal incentives of Rs. 8,450 crore ($1.3 billion).

It has been observed that the exports have declined from $468 billion to $437 billion between 2014-15 and 2016-17. The external trade performance of India has been critical. As a result, the current account deficit in the first quarter of the current fiscal year has reached a four year high of 2.6%. The most disturbing aspect is that this trend is still continuing. An important role in this is played by the unpredictability concerning the execution of the Good and Services Tax (GST). There are very less chances of any improvement in the situation because processing of refunds to exporters under GST has influenced trading activities. Therefore, the so called incentives provided in the mid term review should contribute in increasing of exports to an extent. There is a need for the Indian policy makers to understand that the trade challenges for India are structural. These cannot be repaired by quick solutions. The Government needs to deeply investigate the structural fragility of the trade policy before India loses its comparative advantage to world markets.
