Abu Bakarr Kanu
Abu Bakarr Kanu is a Sierra Leonean analytical chemist who is a professor at Winston-Salem State University. His research considers separation-type instrumentation for the rapid analysis of chemical and biological compounds. Kanu is also involved with education and outreach programmes, and works to bring hands-on chemistry lessons to young people in Sierra Leone. Early life and education Kanu was the first member of his family to attend university. He attended University of Sierra Leone, where he studied chemistry in Fourah Bay College. He was involved with track and field as an undergraduate student. Kanu was awarded a Commonwealth Scholarship, and moved from Sierra Leone to Manchester for his graduate studies. When he arrived at the University of Manchester Kanu started to work on gas chromatography–mass spectrometry. For his doctoral degree he developed miniaturised systems for environmental monitoring. His doctoral research formed the basis of two patents focussing on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Analytical Chemists
Analytical chemistry studies and uses instruments and methods to separate, identify, and quantify matter. In practice, separation, identification or quantification may constitute the entire analysis or be combined with another method. Separation isolates analytes. Qualitative analysis identifies analytes, while quantitative analysis determines the numerical amount or concentration. Analytical chemistry consists of classical, wet chemical methods and modern, instrumental methods. Classical qualitative methods use separations such as precipitation, extraction, and distillation. Identification may be based on differences in color, odor, melting point, boiling point, solubility, radioactivity or reactivity. Classical quantitative analysis uses mass or volume changes to quantify amount. Instrumental methods may be used to separate samples using chromatography, electrophoresis or field flow fractionation. Then qualitative and quantitative analysis can be performed, often with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Year Of Birth Missing (living People)
A year or annus is the orbital period of a planetary body, for example, the Earth, moving in its orbit around the Sun. Due to the Earth's axial tilt, the course of a year sees the passing of the seasons, marked by change in weather, the hours of daylight, and, consequently, vegetation and soil fertility. In temperate and subpolar regions around the planet, four seasons are generally recognized: spring, summer, autumn and winter. In tropical and subtropical regions, several geographical sectors do not present defined seasons; but in the seasonal tropics, the annual wet and dry seasons are recognized and tracked. A calendar year is an approximation of the number of days of the Earth's orbital period, as counted in a given calendar. The Gregorian calendar, or modern calendar, presents its calendar year to be either a common year of 365 days or a leap year of 366 days, as do the Julian calendars. For the Gregorian calendar, the average length of the calendar year (the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Green Chemistry
Green chemistry, also called sustainable chemistry, is an area of chemistry and chemical engineering focused on the design of products and processes that minimize or eliminate the use and generation of hazardous substances. While environmental chemistry focuses on the effects of polluting chemicals on nature, green chemistry focuses on the environmental impact of chemistry, including lowering consumption of nonrenewable resources and technological approaches for preventing pollution. The overarching goals of green chemistry—namely, more resource-efficient and inherently safer design of molecules, materials, products, and processes—can be pursued in a wide range of contexts. History Green chemistry emerged from a variety of existing ideas and research efforts (such as atom economy and catalysis) in the period leading up to the 1990s, in the context of increasing attention to problems of chemical pollution and resource depletion. The development of green chemistry in Europe a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sierra Leone Civil War
The Sierra Leone Civil War (1991–2002), or the Sierra Leonean Civil War, was a civil war in Sierra Leone that began on 23 March 1991 when the Revolutionary United Front (RUF), with support from the special forces of Liberia, Liberian dictator Charles Taylor (Liberian politician), Charles Taylor's National Patriotic Front of Liberia (NPFL), intervened in Sierra Leone in an attempt to overthrow the Joseph Momoh government. The resulting civil war lasted 11 years, enveloped the country, and left over 50,000 dead.Gberie, p. 6 During the first year of the war, the RUF took control of large swathes of territory in eastern and southern Sierra Leone, which were rich in alluvial diamonds. The government's ineffective response to the RUF, and the disruption in government diamond production, precipitated a military ''coup d'état'' in April 1992 by the National Provisional Ruling Council (NPRC).Gberie, p. 103 By the end of 1993, the Republic of Sierra Leone Armed Forces, Sierra Leone Ar ...

National Organization For The Professional Advancement Of Black Chemists And Chemical Engineers
The National Organization for the Professional Advancement of Black Chemists and Chemical Engineers or NOBCChE (pronounced No-be-shay) is a nonprofit, professional organization. NOBCChE's goal is to increase the number of minorities in science, technology, and engineering fields. The organization accomplishes this by creating bonds with professionals working at science-related companies and faculty at local school districts in order to get more minorities to pursue a career in science and engineering fields. NOBCChE focuses on establishing diversity programs for the professional development of young kids and to spread knowledge in science and engineering. NOBCChE chapters can be found nationwide. History NOBCChE was co-founded in 1972 by a group of chemists and chemical engineers. Initially, the organization was financially aided by the Haas Community Fund and Drexel University. After receiving positive feedback and interest from other black chemists and chemical engineers, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polydimethylsiloxane
Polydimethylsiloxane (PDMS), also known as dimethylpolysiloxane or dimethicone, belongs to a group of polymeric organosilicon compounds that are commonly referred to as silicones. PDMS is the most widely used silicon-based organic polymer, as its versatility and properties lead to many applications. It is particularly known for its unusual rheological (or flow) properties. PDMS is optically clear and, in general, inert, non-toxic, and non-flammable. It is one of several types of silicone oil (polymerized siloxane). Its applications range from contact lenses and medical devices to elastomers; it is also present in shampoos (as it makes hair shiny and slippery), food (antifoaming agent), caulk, lubricants and heat-resistant tiles. Structure The chemical formula of PDMS is , where ''n'' is the number of repeating monomer units.Mark, J. E.; Allcock, H. R.; West, R. “Inorganic Polymers” Prentice Hall, Englewood, NJ: 1992. . Industrial synthesis can begin from dimethyldichloro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
University Of Sierra Leone
The University of Sierra Leone is the name of the former unitary public university system in Sierra Leone. Established in February 1827, it is the oldest university in Africa. As of May 2005, the University of Sierra Leone was reconstituted into the individual colleges of Fourah Bay College and Njala University college. History It has its origins in the Fourah Bay College, which was established as an Anglican missionary school by the Church Missionary Society with support from Charles MacCarthy, the governor of Sierra Leone. Samuel Ajayi Crowther was the first student to enroll at Fouray Bay. Fourah Bay College soon became a magnet for Krio and other Africans seeking higher education in British West Africa. These included Nigerians, Ghanaians, Ivorians and many more, especially in the fields of theology and education. It was the first western-style university in West Africa. Under colonialism, Freetown was known as "the Athens Athens ( ; el, Αθήνα, Athína ; g ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
