Dopant
A dopant, also called a doping agent, is a trace of impurity element that is introduced into a chemical material to alter its original electrical or optical properties. The amount of dopant necessary to cause changes is typically very low. When doped into crystalline substances, the dopant's atoms get incorporated into its crystal lattice. The crystalline materials are frequently either crystals of a semiconductor such as silicon and germanium for use in solid-state electronics, or transparent crystals for use in the production of various laser types; however, in some cases of the latter, noncrystalline substances such as glass can also be doped with impurities. In solid-state electronics using the proper types and amounts of dopants in semiconductors is what produces the p-type semiconductors and n-type semiconductors that are essential for making transistors and diodes. Transparent crystals Lasing media The procedure of doping tiny amounts of the metals chromium (Cr), ...

Doping (semiconductor)
In semiconductor production, doping is the intentional introduction of impurities into an intrinsic semiconductor for the purpose of modulating its electrical, optical and structural properties. The doped material is referred to as an extrinsic semiconductor. Small numbers of dopant atoms can change the ability of a semiconductor to conduct electricity. When on the order of one dopant atom is added per 100 million atoms, the doping is said to be ''low'' or ''light''. When many more dopant atoms are added, on the order of one per ten thousand atoms, the doping is referred to as ''high'' or ''heavy''. This is often shown as ''n+'' for n-type doping or ''p+'' for p-type doping. (''See the article on semiconductors for a more detailed description of the doping mechanism.'') A semiconductor doped to such high levels that it acts more like a conductor than a semiconductor is referred to as a degenerate semiconductor. A semiconductor can be considered i-type semiconductor if it has ...

Aircraft Dope
Aircraft dope is a plasticised lacquer that is applied to fabric-covered aircraft. It tightens and stiffens fabric stretched over airframes, which renders them airtight and weatherproof, increasing their durability and lifespan.Crane, Dale: ''Dictionary of Aeronautical Terms, third edition'', page 170. Aviation Supplies & Academics, 1997. The technique has been commonly applied to both full-size and flying models of aircraft. Attributes Doping techniques have been employed in aircraft construction since the dawn of heavier-than-air flight; the fabric of the ground-breaking Wright Flyer had benefitted from doping, as did many of the aircraft that soon followed. Without the application of dope, fabric coverings lacked durability while being highly flammable, both factors rendering them far less viable. By the 1910s, a wide variety of doping agents had entered widespread use while entirely original formulas were being regularly introduced in the industry. Typical doping agents in ...

Doping In Sport
In competitive sports, doping is the use of banned athletic performance-enhancing drugs by athletic competitors as a way of cheating in sports. The term ''doping'' is widely used by organizations that regulate sporting competitions. The use of drugs to enhance performance is considered unethical, and therefore prohibited, by most international sports organizations, including the International Olympic Committee. Furthermore, athletes (or athletic programs) taking explicit measures to evade detection exacerbate the ethical violation with overt deception and cheating. The origins of doping in sports go back to the very creation of sport itself. From ancient usage of substances in chariot racing to more recent controversies in doping in baseball, doping in tennis, doping at the Olympic Games, and doping at the Tour de France, popular views among athletes have varied widely from country to country over the years. The general trend among authorities and sporting organizations over the ...

Abortion Doping
Abortion doping refers to the rumoured practice of purposely inducing pregnancy specifically for athletic performance-enhancing benefits, and then aborting the pregnancy. Rumours and allegations began during international sporting events in the mid-twentieth century, and a number of doctors and scientists have repeated claims about it, but it remains unproven, and is often regarded as a myth. Potential physical benefits Hormonal and other changes in pregnancy affect physical performance. In the first three months it is known that a woman's body produces a natural surplus of red blood cells, which are well supplied with oxygen-carrying hemoglobin, in order to support the growing fetus. Other potential advantages are obtained from the surge in hormones that pregnancy induces, predominantly progesterone and estrogen, but also testosterone, which could increase muscle strength. Increases in hormones like relaxin, which loosens the hip joints to prepare for childbirth, may have a perform ...

Blood Doping
Blood doping is a form of doping in which the number of red blood cells in the bloodstream is boosted in order to enhance athletic performance. Because such blood cells carry oxygen from the lungs to the muscles, a higher concentration in the blood can improve an athlete's aerobic capacity (VO2 max) and endurance. Blood doping can be achieved by making the body produce more red blood cells itself using drugs, giving blood transfusions either from another person or back to the same individual, or by using blood substitutes. Many methods of blood doping are illegal, particularly in professional sports where it is considered to give an artificial advantage to the competitor. Anti-doping agencies use tests to try to identify individuals who have been blood doping using a number of methods, typically by analysing blood samples from the competitors. History Blood doping is defined as the use of illicit products (e.g. erythropoietin (EPO), darbepoetin-alfa, hypoxia-inducible factor (H ...

Boosting (doping)
Boosting is a method of inducing autonomic dysreflexia with the intention of enhancing performance in sport. It can be used by an athlete with a spinal cord injury to increase their blood pressure and is performed by causing a painful stimulus in the lower part of the body. The International Paralympic Committee (IPC) banned the practice in 1994, but many competitors with spinal injuries are still thought to be using it as a performance enhancer. Method Athletes with spinal injuries can have difficulties with autonomic functions and their bodies may be unable to control blood pressure and heart rate. Because of this their bodies do not adapt to the increased demand of physical activity. Without these changes the athlete can become fatigued and suffer from a lower level of endurance. Boosting works by tricking the body into a state of high blood pressure and heart rate, with an increased utilization of oxygen improving the athlete's performance. Athletes who perform boosting befor ...

Gene Doping
Gene doping is the hypothetical non-therapeutic use of gene therapy by athletes in order to improve their performance in those sporting events which prohibit such applications of genetic modification technology, and for reasons other than the treatment of disease. , there is no evidence that gene doping has been used for athletic performance-enhancement in any sporting events. Gene doping would involve the use of gene transfer to increase or decrease gene expression and protein biosynthesis of a specific human protein; this could be done by directly injecting the gene carrier into the person, or by taking cells from the person, transfecting the cells, and administering the cells back to the person. The historical development of interest in gene doping by athletes and concern about the risks of gene doping and how to detect it moved in parallel with the development of the field of gene therapy, especially with the publication in 1998 of work on a transgenic mouse overexpressing insul ...

Stem Cell Doping
Stem cell doping is the postulated practice of enhancing athletic performance through various beneficial effects of stem cells injected into the bloodstream or otherwise introduced into the body. Currently there are no documented cases of stem cell doping, but there are suspicions that the practice may already be emerging.

Technology Doping
Technology doping is the practice of gaining a competitive advantage using sports equipment. The World Anti-Doping Agency (WADA) considers prohibiting technologies if they are "performance-enhancing" or "being against the spirit of the sport". In 2006, WADA initiated a consultation on technology doping which is now officially recognised as a threat, whilst the decision to allow or ban a new technology, specifically relating to sports equipment, is the responsibility of each sport’s own governing body. Gray area Since most sports require equipment of some sort, it can be tricky to determine what is technology doping and what is not. The governing authorities of different sports usually make judgment calls about the technological advances in their sport’s equipment. Technological advancements are often allowed unless the governing authorities feel they threaten the integrity of the sport. A report released immediately before the 2012 Summer Olympics quotes an extensive pub ...

Doping In China
China, officially the People's Republic of China (PRC), conducted a state-sanctioned doping programme on athletes in the 1980s and 1990s. The majority of revelations of Chinese doping have focused on swimmers and track and field athletes, such as Ma Junren's ''Ma Family Army'' (). More recently, three Chinese weightlifters have been stripped of their gold Olympic medals for doping at the 2008 Summer Olympics. China's doping has been attributed to a number of factors, such as the exchange of culture and technology with foreign countries. Some commentators have compared it to the doping programme in East Germany. Chinese swimming performances in the 1990s In 1992 the number of Chinese swimmers in the top 25 world rankings soared from a plateau of less than 30 to 98, with all but 4 of the 98 swimmers female. Their improvement rate was much better than could have been expected as a result of normal growth and development. China subsequently performed beyond expectations to win 1 ...
