Chemistry
Chemistry is the science, scientific study of the properties and behavior of matter. It is a natural science that covers the Chemical element, elements that make up matter to the chemical compound, compounds made of atoms, molecules and ions: their composition, structure, properties, behavior and the changes they undergo during a Chemical reaction, reaction with other Chemical substance, substances. Chemistry also addresses the nature of chemical bonds in chemical compounds. In the scope of its subject, chemistry occupies an intermediate position between physics and biology. It is sometimes called the central science because it provides a foundation for understanding both Basic research, basic and Applied science, applied scientific disciplines at a fundamental level. For example, chemistry explains aspects of plant growth (botany), the formation of igneous rocks (geology), how atmospheric ozone is formed and how environmental pollutants are degraded (ecology), the properties ...

Convention On The Marking Of Plastic Explosives
The Convention on the Marking of Plastic Explosives for the Purpose of Detection is a multilateral anti-terrorism treaty that aims to prohibit and prevent the manufacture or storage of unmarked plastic explosives. Content A state that ratifies the Convention agrees to prohibit the manufacture, storage, transport, or entry of unmarked plastic explosives in its territory. Plastic explosives are not prohibited by the treaty, but it mandates that when they are produced they are marked with a chemical taggant (specified in the treaty's Technical Annex) which can facilitate future identification purposes. The Convention also establishes an International Explosives Technical Commission, which is composed of experts in the field of explosives manufacturing and explosives detection. The Commission can propose amendments to the Technical Annex of the treaty. Conclusion and ratifications The Convention was concluded at the ICAO International Conference on Air Law in Montreal on 1 March 1 ...

Canadian Chemists
Canadians (french: Canadiens) are people identified with the country of Canada. This connection may be residential, legal, historical or cultural. For most Canadians, many (or all) of these connections exist and are collectively the source of their being ''Canadian''. Canada is a multilingual and multicultural society home to people of groups of many different ethnic, religious, and national origins, with the majority of the population made up of Old World immigrants and their descendants. Following the initial period of French and then the much larger British colonization, different waves (or peaks) of immigration and settlement of non-indigenous peoples took place over the course of nearly two centuries and continue today. Elements of Indigenous, French, British, and more recent immigrant customs, languages, and religions have combined to form the culture of Canada, and thus a Canadian identity. Canada has also been strongly influenced by its linguistic, geographic, and e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Vapor Pressure
Vapor pressure (or vapour pressure in English-speaking countries other than the US; see spelling differences) or equilibrium vapor pressure is defined as the pressure exerted by a vapor in thermodynamic equilibrium with its condensed phases (solid or liquid) at a given temperature in a closed system. The equilibrium vapor pressure is an indication of a liquid's evaporation rate. It relates to the tendency of particles to escape from the liquid (or a solid). A substance with a high vapor pressure at normal temperatures is often referred to as '' volatile''. The pressure exhibited by vapor present above a liquid surface is known as vapor pressure. As the temperature of a liquid increases, the kinetic energy of its molecules also increases. As the kinetic energy of the molecules increases, the number of molecules transitioning into a vapor also increases, thereby increasing the vapor pressure. The vapor pressure of any substance increases non-linearly with temperature according ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mononitrotoluene
Mononitrotoluene or nitrotoluene (MNT or NT), is any of three organic compounds with the formula C6H4(CH3)(NO2). They can be viewed as nitro derivatives of toluene or as methylated derivatives of nitrobenzene. Mononitrotoluene comes in three isomers, differing by the relative position of the methyl and nitro groups. All are pale yellow with faint fragrances: * ''ortho''-nitrotoluene (ONT), ''o''-nitrotoluene, or 2-nitrotoluene. m.p. = -10.4 °C * ''meta''-nitrotoluene (MNT), ''m''-nitrotoluene, or 3-nitrotoluene. m.p. = 16 °C * ''para''-nitrotoluene (PNT), ''p''-nitrotoluene, or 4-nitrotoluene. m.p. = 44.5 °C Typical use of nitrotoluene is in production of pigments, antioxidants, agricultural chemicals, and photographic chemicals. ''Ortho''-mononitrotoluene and ''para''-mononitrotoluene can be also used as detection taggants for explosive detection.

Ethylene Glycol Dinitrate
Ethylene glycol dinitrate, abbreviated EGDN and NGC, also known as Nitroglycol, is a colorless, oily, explosive liquid obtained by nitration, nitrating ethylene glycol. It is similar to nitroglycerine in both manufacture and properties, though it is more volatile and less viscosity, viscous. Unlike nitroglycerine, the chemical has a perfect oxygen balance, meaning that its ideal exothermic decomposition would completely convert it to low energy carbon dioxide, water, and nitrogen gas, with no excess unreacted substances, without needing to react with anything else. History and production Pure EGDN was first produced by the Belgian chemist Louis Henry (1834–1913) in 1870 by dropping a small amount of ethylene glycol into a mixture of nitric acid, nitric and sulfuric acids cooled to 0 °C. The previous year, Friedrich August Kekulé von Stradonitz, August Kekulé had produced EGDN by the nitration of ethylene, but this was actually contaminated with beta-nitroethyl nitrate. ...
