Organic solar cellAn organic solar cell (OSC) or plastic solar cell is a type of photovoltaic that uses organic electronics, a branch of electronics that deals with conductive organic polymers or small organic molecules, for light absorption and charge transport to produce electricity from sunlight by the photovoltaic effect. Most organic photovoltaic cells are polymer solar cells. The molecules used in organic solar cells are solution-processable at high throughput and are cheap, resulting in low production costs to fabricate a large volume.
Molecular modellingMolecular modelling encompasses all methods, theoretical and computational, used to model or mimic the behaviour of molecules. The methods are used in the fields of computational chemistry, drug design, computational biology and materials science to study molecular systems ranging from small chemical systems to large biological molecules and material assemblies. The simplest calculations can be performed by hand, but inevitably computers are required to perform molecular modelling of any reasonably sized system.
Co-operative economicsCooperative (or co-operative) economics is a field of economics that incorporates cooperative studies and political economy toward the study and management of cooperatives. History of the cooperative movement Cooperative economics developed as both a theory and a concrete alternative to industrial capitalism in the late 1700s and early 1800s. As such, it was a form of stateless socialism. The term "socialism," in fact, was coined in The Cooperative Magazine in 1827.
Spontaneous orderSpontaneous order, also named self-organization in the hard sciences, is the spontaneous emergence of order out of seeming chaos. The term "self-organization" is more often used for physical changes and biological processes, while "spontaneous order" is typically used to describe the emergence of various kinds of social orders in human social networks from the behavior of a combination of self-interested individuals who are not intentionally trying to create order through planning.
Structural adjustmentStructural adjustment programs (SAPs) consist of loans (structural adjustment loans; SALs) provided by the International Monetary Fund (IMF) and the World Bank (WB) to countries that experience economic crises. Their stated purpose is to adjust the country's economic structure, improve international competitiveness, and restore its balance of payments. The IMF and World Bank (two Bretton Woods institutions) require borrowing countries to implement certain policies in order to obtain new loans (or to lower interest rates on existing ones).
Fluxional moleculeIn chemistry and molecular physics, fluxional (or non-rigid) molecules are molecules that undergo dynamics such that some or all of their atoms interchange between symmetry-equivalent positions. Because virtually all molecules are fluxional in some respects, e.g. bond rotations in most organic compounds, the term fluxional depends on the context and the method used to assess the dynamics. Often, a molecule is considered fluxional if its spectroscopic signature exhibits line-broadening (beyond that dictated by the Heisenberg uncertainty principle) due to chemical exchange.
EthylenediamineEthylenediamine (abbreviated as en when a ligand) is the organic compound with the formula C2H4(NH2)2. This colorless liquid with an ammonia-like odor is a basic amine. It is a widely used building block in chemical synthesis, with approximately 500,000 tonnes produced in 1998. Ethylenediamine is the first member of the so-called polyethylene amines. Ethylenediamine is produced industrially by treating 1,2-dichloroethane with ammonia under pressure at 180 °C in an aqueous medium: In this reaction hydrogen chloride is generated, which forms a salt with the amine.
Import substitution industrializationImport substitution industrialization (ISI) is a trade and economic policy that advocates replacing foreign imports with domestic production. It is based on the premise that a country should attempt to reduce its foreign dependency through the local production of industrialized products. The term primarily refers to 20th-century development economics policies, but it has been advocated since the 18th century by economists such as Friedrich List and Alexander Hamilton.
