What is Thermal Runaway in Lithium-Ion Batteries?
Thermal runaway is a violent chain reaction of exothermic chemical reactions resulting in an uncontrollable increase in system temperature. Now, where does this reaction might unfold? Batteries and energy storage systems, which are integral parts of tech around us, are the main stage for this drama. They sometimes fall victim to thermal runaway, turning a peaceful power source into a potential ...

From economic theories to pollution permits
Permits to pollute have occupied too large a place in negotiations. Their originality has made it possible, sometimes without limit, to mobilise new theories maladapted to the problem, as their goal was elsewhere; the complexity of implementation they presuppose has mobilised much energy, the long-term consequences are unpredictable, focusing solely on the economic aspect of the problems, and ...

Universal equality of masses of nucleons and binding energy of the nucleus
There are two inherent observations: firstly, masses of nucleons are fundamental constants, i.e., they are the same universally (inside and outside the nucleus in all cases); and secondly, nuclei possess Binding Energy (BE) (Δmc?) owing to a mass defect. To explain these observations, in the case of the deuteron (BE = 2.2244 MeV), the mass defect of nucleons must be 0.002388 amu or about 0.118 ...

Treaty on the non-proliferation of nuclear weapons and its recent issues: a legal perspective
The treaty on the non-proliferation of nuclear weapons (NPT) is the cornerstone for a nuclear non-proliferation regime. Nuclear proliferation is a central global security issue and the most dangerous issue in the world of the coming era. After the failure of the NPT 2005 review conference, there is no doubt that the present crisis is the worst that the NPT has faced. There are many positive ...

INDO-US 123 agreement - a saga of controversies and compromises
The text of the Agreement for Cooperation between The Government of India and The Government of USA concerning Peaceful Uses of Nuclear Energy (123 Agreement) has been released for public scrutiny before final execution. It has faced unprecedented criticism in both countries and is, perhaps, one of the most difficult negotiations carried out in this field in recent times. The contents of the ...

Zinc batteries, back to sources
The alkaline primary battery is by far the most used electrochemical energy source in the world. But non rechargeable batteries are too expensive for many applications where rechargeable batteries are rather used. First came Ni-Cd batteries, then Ni-MH. These batteries deliver a relatively competitive energy source but they also have some drawbacks. They store at most two times less energy ...

Latin American commitment in support of the IAEA role on non-proliferation control
The Latin American and Caribbean countries' contribution to the implementation of worldwide nuclear non-proliferation is well demonstrated by the establishment of a nuclear weapons free-zone and by their permanent support of IAEA safeguards. The 'Treaty for the Prohibition of Nuclear Weapons in Latin America and the Caribbean', encompassing all region territories from Mexico to Argentina and ...

The reemergence of state-centred power sector reform: the case of South Africa
The power sector in South Africa is dominated by the state-owned, vertically integrated utility, Eskom. An Energy Policy White Paper and subsequent Cabinet decisions laid out a path of managed liberalisation. However, government still experiences ambivalence and doubts around restructuring. The "standard" model of power sector reform of the past decade – vertical and horizontal unbundling, ...

Optimal minimal maintenance of deteriorating system subject to exponential failures with maintenance and repair of general distributions
The article presents a model of multistage degraded system subject to minimal maintenance, random failures and partial repairs. Constant state dependent transition rates for the degradation failure processes are considered while the minimal maintenance and the partial repairs follow general distributions with square of coefficient of variation less than or equal to one and state dependent which ...

India and the International Atomic Energy Agency
India is one of the founder members of the International Atomic Energy Agency. The sustained growth of its nuclear programme has accorded a unique distinction to India of being a developing country with strong foundations in advanced nuclear technology. This perspective of being a technologically advanced developing country has guided many of India's interactions on the IAEA platform.Keywords: ...

The interlinkage of energy and poverty: evidence from India
Worldwide, some two billion people live without access to modern energy supply. About 1.6 billion people live without access to electricity. Alleviating this "energy poverty" is a factor in reaching most of the UN's millennium goals. In our contribution to the debate on how to achieve this aim, we discuss the nexus between energy and poverty in developing countries. In order to deal with all ...
