Bengal Presidency
The Bengal Presidency, officially the Presidency of Fort William and later Bengal Province, was a subdivision of the British Empire in India. At the height of its territorial jurisdiction, it covered large parts of what is now South Asia and Southeast Asia. Bengal proper covered the ethno-linguistic region of Bengal (present-day Bangladesh and the Indian state of West Bengal). Calcutta, the city which grew around Fort William, was the capital of the Bengal Presidency. For many years, the Governor of Bengal was concurrently the Viceroy of India and Calcutta was the de facto capital of India until 1911. The Bengal Presidency emerged from trading posts established in Mughal Bengal during the reign of Emperor Jahangir in 1612. The East India Company (HEIC), a British monopoly with a Royal Charter, competed with other European companies to gain influence in Bengal. After the decisive overthrow of the Nawab of Bengal in 1757 and the Battle of Buxar in 1764, the HEIC expanded ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Diazine
In organic chemistry, diazines are a group of organic compounds having the molecular formula . Each contains a benzene ring in which two of the C-H fragments have been replaced by isolobal nitrogen. There are three structural isomers: * pyridazine (1,2-diazine) 55px * pyrimidine (1,3-diazine) 45px * pyrazine (1,4-diazine) 50px See also * 6-membered rings with one nitrogen atom: pyridines * 6-membered rings with three nitrogen atoms: triazines * 6-membered rings with four nitrogen atoms: tetrazines * 6-membered rings with five nitrogen atoms: pentazines * 6-membered rings with six nitrogen atoms: hexazine Hexazine (also known as hexaazabenzene) is a hypothetical allotrope of nitrogen composed of 6 nitrogen atoms arranged in a ring-like structure analogous to that of benzene. It would be the final member of the azabenzene (azine) series, in which al ...s References {{Reflist Simple aromatic rings ...

Exciton
An exciton is a bound state of an electron and an electron hole which are attracted to each other by the electrostatic Coulomb force. It is an electrically neutral quasiparticle that exists in insulators, semiconductors and some liquids. The exciton is regarded as an elementary excitation of condensed matter that can transport energy without transporting net electric charge. An exciton can form when a material absorbs a photon of higher energy than its bandgap. This excites an electron from the valence band into the conduction band. In turn, this leaves behind a positively charged electron hole (an abstraction for the location from which an electron was moved). The electron in the conduction band is then less attracted to this localized hole due to the repulsive Coulomb forces from large numbers of electrons surrounding the hole and excited electron. These repulsive forces provide a stabilizing energy balance. Consequently, the exciton has slightly less energy than the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
British India
The provinces of India, earlier presidencies of British India and still earlier, presidency towns, were the administrative divisions of British governance on the Indian subcontinent. Collectively, they have been called British India. In one form or another, they existed between 1612 and 1947, conventionally divided into three historical periods: *Between 1612 and 1757 the East India Company set up Factory (trading post), factories (trading posts) in several locations, mostly in coastal India, with the consent of the Mughal emperors, Maratha Empire or local rulers. Its rivals were the merchant trading companies of Portugal, Denmark, the Netherlands, and France. By the mid-18th century, three ''presidency towns'': Madras, Bombay and Calcutta, had grown in size. *During the period of Company rule in India (1757–1858), the company gradually acquired sovereignty over large parts of India, now called "presidencies". However, it also increasingly came under British government over ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

A presidency is an administration or the executive, the collective administrative and governmental entity that exists around an office of president of a state or nation. Although often the executive branch of government, and often personified by a single elected person who holds the office of "president", in practice, the presidency includes a much larger collective of people, such as chiefs of staff, advisers and other bureaucrats. Although often led by a single person, presidencies can also be of a collective nature, such as the presidency of the European Union is held on a rotating basis by the various national governments of the member states. Alternatively, the term presidency can also be applied to the governing authority of some churches, and may even refer to the holder of a non-governmental office of president in a corporation, business, charity, university, etc. or the institutional arrangement around them. For example, "the presidency of the Red Cross refused to support h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Physical Chemist
Physical chemistry is the study of macroscopic and microscopic phenomena in chemical systems in terms of the principles, practices, and concepts of physics such as motion, energy, force, time, thermodynamics, quantum chemistry, statistical mechanics, analytical dynamics and chemical equilibria. Physical chemistry, in contrast to chemical physics, is predominantly (but not always) a supra-molecular science, as the majority of the principles on which it was founded relate to the bulk rather than the molecular or atomic structure alone (for example, chemical equilibrium and colloids). Some of the relationships that physical chemistry strives to resolve include the effects of: # Intermolecular forces that act upon the physical properties of materials ( plasticity, tensile strength, surface tension in liquids). # Reaction kinetics on the rate of a reaction. # The identity of ions and the electrical conductivity of materials. # Surface science and electrochemistry of cell mem ...
